docs(quick-261016-s8x): PaymentGateway: banner bottom margin and hide disabled sections from admin navigation

- .summer-partial .summer-callout:not(:last-child) gets margin-bottom: 12px,
  so a feature-off callout no longer touches the stats strip under it
- scoped to rendered partials: FormField.vue's field notice and the hint
  partials, whose callout is the last child, are unchanged

+# Decision: go-redis v9 and otter v2 for cooler
+
+**Date:** 2026-10-15
+**Status:** Accepted
+**Context:** Phase 19.3 (`cooler` module, D-06..D-09, D-13), 19.3-RESEARCH.md Standard Stack and Package Legitimacy Audit
+
+## Decision
+
+The new `cooler` module (cache drivers, the Redis-backed rate-limit store, later the site-cache purge) depends on:
+
+- **`github.com/redis/go-redis/v9` at v9.23.0** as the Redis client (locked by D-07).
+  - The official Redis client for Go, MIT/BSD, maintained by Redis.
+  - `redis.ParseURL` reads `redis://`, `rediss://` (TLS) and `unix://` URLs, so the one config key `redis.url` covers local, managed and socket setups.
+  - `redis.NewScript` with `Script.Run` sends EVALSHA and falls back to EVAL on NOSCRIPT, which the atomic fixed-window rate-limit script needs.
+  - `redis.NewClient` does not dial; the first command does. `cooler.FromApp` relies on this to give jobs and console commands a cache without a connection at construction.
+  - cooler sets `DisableIdentity` and disables maintenance notifications, so the client sends no `CLIENT SETINFO` or `CLIENT MAINT_NOTIFICATIONS` handshake to servers that do not know them.
+- **`github.com/maypok86/otter/v2` at v2.3.0** as the in-process memory cache driver (D-07 discretion: otter or a stdlib map).
+  - Bounded size (`MaximumSize`), per-entry expiry (`ExpiryCalculator`), lock-scoped `Compute` for an atomic `Increment`, an injectable clock for tests. No runtime dependencies (its go.mod requires only testify, for its own tests).
+  - Already named for `cooler` in `.planning/research/ARCHITECTURE.md` and `.planning/research/go-ecosystem.md`.
+  - **A stdlib map was rejected:** a map with a mutex and a sweeper is about a hundred lines, but it is unbounded. Cache keys often derive from request data (`user:<id>`, a client IP), so the map grows without limit; bounding it means writing an LRU by hand, which is exactly what otter already does well.
+
+Both versions were checked on proxy.golang.org during research (existence, publish time, VCS origin `github.com/redis/go-redis` and `github.com/maypok86/otter`).
+
+## Related dependencies
+
+- **`github.com/alicebob/miniredis/v2` v2.40.0, test-only.** An in-process Redis for the `-short` unit tests of cooler (EVAL/EVALSHA, PTTL, INCRBY, SCAN, UNLINK, `FastForward` for TTLs). The package name came from training knowledge, so it is installed only in plan 05, after a blocking human check of the package. Production code never imports it.
+- **`gocloud.dev/blob/s3blob`**, from the already required `gocloud.dev` v0.46.0. Plan 03 imports it only from a file under the `summercms_s3` build tag, so binaries built without the tag carry no S3 code. The import adds the AWS SDK v2 modules to `go.mod` and `go.sum` as indirect requirements.
+- **Docker-backed Redis tests** use the generic `testcontainers.Run` with the `redis:7-alpine` image from the already required `github.com/testcontainers/testcontainers-go`. No testcontainers Redis sub-module is added.
+
+## Consequences
+
+- `go.mod` requires `github.com/redis/go-redis/v9 v9.23.0` and `github.com/maypok86/otter/v2 v2.3.0`; `modules/cooler` is the only importer of both. `surf` imports `cooler`, never go-redis directly.
+- Config keys introduced with them: `redis.url`, `cache.driver` (`memory`|`redis`), `cache.prefix`, `cache.memory.max_entries`, `http.rate_limit.store` (`memory`|`redis`). Apps and deploy docs depend on these once they ship.
+- Replacing the Redis client later means re-validating the rate-limit Lua script and the key layout (`<prefix>cache:`, `<prefix>rl:`) against the new client.

+# Release the 19.3 gap closure as v0.2.0, not v0.1.28
+
+**Date:** 2026-10-15
+**Decision:** The next framework tag after v0.1.27 is **v0.2.0**.
+
+## Why
+
+The 19.3-06 review fixes include changes that can make an app that boots on v0.1.27 refuse to boot after the upgrade:
+
+- WR-05: in production, a token cookie whose `Secure` is inferred as false (http or empty `app.url`) is refused at boot.
+- WR-04: credentialed CORS refuses wildcard-host and unanchored origin patterns at boot.
+
+Smaller behaviour changes ride along: site-cache purges run queued after commit (WR-01), protected uploads into a `public_url` bucket are refused (WR-07), Journal's old purge keys are deprecated aliases.
+
+In a v0.x Go module the minor version is the signal for "check your config before upgrading". Consumers pin exact versions, so the bump costs nothing technically.
+
+## Consequences
+
+- Plugins and apps move with `go get git.golem15.com/golem15/summercms@v0.2.0`.
+- The docs and the release notes carry an "Upgrading to 0.2" section naming the two boot refusals and the config that fixes each.
+- From here, the minor version is bumped when an upgrade can refuse a previously valid config or changes a documented behaviour; patch versions stay safe to take without reading.

+# Phase 18.1 Plan 06: Tests, gate and release Summary
+
+**Every behaviour of plans 01 to 05 now has a unit or Postgres test across the framework, pgsub, pgstripe and the layer. The nine PHP pgstripe tests map to named Go cases. `scripts/check-phase18.1.sh --all` is green with Postgres required. The tests exposed one framework bug (the localized list schema dropped `reorder.flat`), which is now fixed. On the human's "push-all" the phase was published as framework v0.1.26 and layer v0.2.0, and both plugins now require v0.1.26.**
+
+## Performance
+
+- **Duration:** about 50 min. Tasks 1 to 4 ran from 18:24:41Z to 19:09Z, then the checkpoint, then the release and close-out from 19:10Z to about 19:15Z.
+- **Tasks:** 5 of 5.
+- **Files:** 39 across four repositories, plus the planning docs.
+
+## Task Commits
+
+| Task | Repo | Commit | Message |
+|------|------|--------|---------|
+| 1 | summercms.go | `3cc4a5f` | test: fail-closed phase 18.1 gate with detector self-test |
+| 2 | summercms.go | `0f09586` | fix: keep reorder.flat in the localized list schema |
+| 2 | summercms.go | `323b6d6` | test: taglist and flat reorder matrices, partitioned flat smoke, admin specs |
+| 2 | vue-paymentgateway-layer | `30046f5` | test: subscription client, flow and component coverage |
+| 3 | sm-paymentgatewaysubscriptions-plugin | `1da437f` | test: pgsub unit and Postgres coverage |
+| 3 | summercms.go | `6f71cd1` | test: require the pgsub tests in the gate |
+| 4 | sm-pgstripe-plugin | `88f9125` | test: decode, job, plan sync, gateway, PHP map and secret coverage |
+| 4 | summercms.go | `7790434` | test: require the pgstripe tests in the gate |
+| 4 | summercms.go | `5c2b0e1` | docs: validated VALIDATION map and deferred items |
+| 5 | sm-paymentgatewaysubscriptions-plugin | `472b75b` | chore: require summercms v0.1.26 |
+| 5 | sm-pgstripe-plugin | `baf3c55` | chore: require summercms v0.1.26 |
+
+**Plan metadata:** the docs commits that add this SUMMARY and the STATE/ROADMAP update, pushed after the tag. The tag is not moved.
+
+## Task 5: release decision
+
+**Reply (verbatim):** "push-all"
+
+This is what was done, in the order of the push sheet. Nothing was force-pushed, and every repository was 0 commits behind its origin before its push.
+
+**Framework**
+- master pushed: `a377953..5c2b0e1`.
+- Annotated tag `v0.1.26` created on `5c2b0e1` (tag object `03c33dd`) and pushed.
+
+**pgsub**
+- Commit `472b75b` raises the require to `git.golem15.com/golem15/summercms v0.1.26`; the replace onto `../summercms.go` is unchanged.
+- `go mod tidy` resolved through the replace, so no proxy fetch was needed (default GOPROXY, no GONOSUMDB) and go.sum is unchanged.
+- vet and the `-short` tests pass.
+- main pushed: `aad4647..472b75b`.
+
+**pgstripe**
+- Commit `baf3c55` makes the same bump, with the same tidy, vet and `-short` results.
+- main pushed: `0313820..baf3c55`.
+
+**Layer**
+- main pushed: `ac2b960..30046f5`.
+- Annotated tag `v0.2.0` created on `30046f5` (tag object `f1107fa`) and pushed.
+
+**Check:** after the pushes, each local branch equals its origin branch:
+
+| Repository | Branch | Hash |
+|------------|--------|------|
+| summercms.go | master | `5c2b0e1` (before this SUMMARY's docs commits, which are pushed afterwards) |
+| pgsub | main | `472b75b` |
+| pgstripe | main | `baf3c55` |
+| layer | main | `30046f5` |
+
+`git ls-remote --tags` shows `v0.1.26` on the framework origin and `v0.2.0` on the layer origin.
+
+## Tests added
+
+**Framework (cabana, admin)**
+- Docker-free tests:
+  - `TestTaglistFieldValidate`: 19 accepted and 17 refused cases, both modes, the locale, multiple fields.
+  - `TestTaglistFieldHydrate`: 12 stored shapes.
+  - `TestReorderFlatNodes`: flat parent 422, duplicate and zero id 422, missing, extra or swapped node 409, a 200-node flat list, and the tree contrast.
+  - `TestReorderFlatCompile` now also checks the localized list schema.
+- Postgres test: the subtest `TestReorderFlatSmoke/partitioned`, over the new in-memory `acme.shelf` fixture.
+- vitest:
+  - 9 TaglistField coverage specs: script markup, Backspace, blur, paste, datalist, customTags, comma string mode, array mode, aria.
+  - 2 flat ReorderView specs: the keyboard and the three drop zones.
+
+**pgsub**
+- Docker-free tests: `TestSubscriptionChecks`, `TestPlanPrices`, `TestFeatureList`, `TestRegistry`, `TestLangParity`. `TestLangParity` checks keys, `:placeholders` and every key the sources name; a planted placeholder mismatch made it fail.
+- Postgres tests:
+  - `TestApplyEvents`: 272 cases (status pairs times cancel flags) against an independent copy of the PHP rule, plus deleted, invoices and refused updates.
+  - `TestClaimEventConcurrent`: two overlapping claims, five rounds, plus a rollback.
+  - `TestUserSubscribable`.
+  - `TestBaselineSchema`: golden names from the PHP dump, jsonb columns, RESTRICT, a re-run, rollback then migrate, the users column only when missing.
+  - `TestServiceAPI`: a probe gateway checks for open transactions and committed customer ids at each call; a sanity subtest proves the probe sees an open transaction.
+  - `TestAdminSyncActions`.
+  - `TestCustomerAPIAuthz`: routes × anonymous, malformed and admin tokens, the owner and another user. It covers the byte-exact none answer and ignored redirect and subscriber fields.
+
+**pgstripe**
+- Docker-free tests: `TestDecodeSubscription`, `TestDecodeInvoice`, `TestJobArgsMinimal` (a fixed key list, no PII).
+- Postgres tests:
+  - `TestSubscriptionJob`: STRIPE-006 rollback through a listener that fails on demand, STRIPE-007 skips, duplicate and concurrent jobs, both shapes.
+  - `TestSyncPlan`.
+  - `TestSubscriptionGateway`.
+  - `TestStripeSubscriptionReliability` and `TestSubscriptionAuthentication` (the PHP map).
+  - Root `TestStripeSubscriptionSecrets`.
+- `TestSDKPin` remains the STRIPE-003 case.
+
+**Layer:** 9 more `subscriptions:` tests (36 in total):
+- refusals passed through unchanged, and the `usePlans` key;
+- a retry after a refusal, and the buttons' copy before a click;
+- the currency prop;
+- the confirmed 404 none answer end to end;
+- the Cancel visibility matrix;
+- the manage flow with 401, 409, 422, 429 and 502;
+- the cancel busy guard.

+
+## VALIDATION
+
+`18.1-VALIDATION.md` is `status: validated`, `nyquist_compliant: true` and `wave_0_complete: true`. It covers every task of plans 01 to 06 and keeps three manual-only rows:
+- the portal `cancel_at` check;
+- a live test-mode checkout;
+- the screens in a browser.
+
+## Decisions Made
+
+- Release per the reply "push-all", in the push sheet order. The tag was set on the code-complete HEAD `5c2b0e1`; the later docs commits are pushed without moving it.
+- The STRIPE-002 payment-notification tests stay Phase 18 scope.
+- The gate copies the Phase 18 detectors instead of sourcing them, and adds a check for the number of tests by name prefix.
+
+## Deviations from Plan
+
+### Auto-fixed Issues
+
+**1. [Rule 1 - Bug] The localized list schema dropped `reorder.flat`**
+- **Found during:** Task 2. This was the deferred item from plan 18.1-04.
+- **Issue:** `ListSchema.Localize` copied only the reorder title and partition, so `GET .../schema/list` answered a flat reorder without `flat: true`.
+- **Fix:** `Flat` is now copied. The README and the docs already described the flag, so no doc change was needed.
+- **Verification:** the RED subtest `TestReorderFlatCompile/the_localized_list_schema_keeps_flat` failed first; its RED evidence was checked as RED_EVIDENCE_OK. It passes after the fix.
+- **Committed in:** `0f09586` (fix), then `323b6d6` (test).
+
+### Adaptations
+
+1. **Test-only wrappers in `modules/cabana/export_test.go`** (`CheckTaglistValues`, `HydrateTaglistFields`, `CheckReorderNodes`, `IsReorderStale`). The existing tests are in package `cabana_test`, which cannot call the unexported helpers.
+2. **The partitioned flat case uses a fixture of its own.** It runs on the in-memory plugin `acme.shelf`, so the catalog fixture is unchanged.
+3. **One shared source scan.** `TestAdminLangParity`'s scan moved into the helper `langUsedKeys`, which `TestLangParity` also uses. The behaviour of the existing test is unchanged.
+4. **A price failure switch in the package Stripe fake** (`failPrices`), so a test can fail the price step after the product step.
+5. **`subscriptions/decode_test.go` is an internal test**, because the decoders are unexported.
+6. **The STRIPE-006 failure is injected through a listener** that fails on demand, registered by the test. The failure then happens after Apply saved the row, which proves that the row and the marker roll back together.
+7. **The gate's layer stage never installs.** If pnpm aborts on the store mismatch, the stage fails and prints the offline, frozen-lockfile recovery command.
+8. **A success-URL case with a fragment was dropped.** Go and PHP both append `?session_id` after a `#fragment`. That is PHP parity, and it is left untested rather than pinned.
+9. **Most coverage tasks had no failing test first.** The tdd="true" coverage tasks tested behaviour that already existed, so only the `reorder.flat` defect produced a failing test before the fix. The plan is `type: execute`, so the plan-level TDD gate does not apply.
+
+**Total deviations:** 1 auto-fixed (Rule 1) and 9 adaptations.
+**Impact on plan:** test-side plumbing only, plus one framework bug fix. No scope or dependency was added.
+
+## Deferred items
+
+| Item | Status |
+|------|--------|
+| `reorder.flat` in the localized list schema | resolved by `0f09586` |
+| pnpm store-dir mismatch (watch item) | resolved: the gate ran the layer suite green from a clean shell, and the layer stage never installs |
+| `vue-paymentgateway-layer/scripts/check-git-install.sh` targets vue-journal-layer | **still open**: no gate or release step runs it |
+
+Because of the last item, an install check of the published `v0.2.0` tag needs a quick task on the layer first.
+
+## Issues Encountered
+
+- **The tool layer unescaped `<` in written test literals.** The affected expectations were rewritten with explicit bytes.
+- **An interactive `cp` alias blocked a file restore after a mutation check.** The file was restored with `command cp -f` and confirmed clean.
+
+## Threat Flags
+
+None. The plan added tests, a one-line framework fix, two go.mod require bumps and the releases.
+- **T-18.1-32:** the gate requires every test by name, and `--self-test` proves its detectors.
+- **T-18.1-33:** every Stripe call in the tests goes to the fakes, and the secrets in tests are test-only literals.
+- **T-18.1-34:** the full gate ran before the human's reply, and the pushes followed the resolvable order without a force push.
+- **T-18.1-SC:** no package was installed.
+
+## Known Stubs
+
+None.
+
+## User Setup Required
+
+None.
+
+## Next Phase Readiness
+
+- The phase is published.
+  - Applications can require `git.golem15.com/golem15/summercms v0.1.26`.
+  - They can pin `vue-paymentgateway-layer#v0.2.0`.
+  - They can build pgsub and pgstripe from main.
+- One limitation remains: pgstripe requires `sm-paymentgatewaysubscriptions-plugin v0.0.0` with a replace, and pgsub has no tag. Building from git without the replace needs a pgsub tag or a pseudo-version, the same as the existing sm-paymentgateway-plugin pattern.
+- Next: `/msd-verify-work 18.1` with the manual-only rows: a live Stripe test-mode checkout, the portal `cancel_at` check and the browser pass.
+
+---
+*Phase: 18.1-payment-gateway-subscriptions*
+*Completed: 2026-10-14*

+    - "CR-01 (deleted before created, review sequence 2): ApplyDeleted on a subscription id with no stored row returns an error wrapping classes.ErrSubscriptionNotStored, so the job rolls its marker back and River retries it instead of committing the marker; a created event retried afterwards stores the state Stripe reports (canceled), so a deleted subscription never comes back active and never fires activated."
+    - "CR-01 (spurious reactivated, review sequence 3): after Service.Cancel set cancel_at_period_end locally, an older queued customer.subscription.updated carrying cancel_at_period_end false applies Stripe's current value (true), so SubscriptionReactivated does not fire."
+    - "CR-01 claim-first is kept (D-11, STRIPE-006/007): a duplicate event is answered from the processed-event marker before any Stripe call, an event of another application (metadata app) is skipped with its marker kept and without a Stripe call, a failed retrieval or a failed Apply leaves no marker and returns the error, and when Stripe answers that the subscription does not exist (404 or resource_missing, ErrSubscriptionMissing) the job applies the event's own snapshot with a Warn log, as before."
+    - "WR-04: Apply resolves the plan by the exact price id (stripe_price_id, then stripe_prices), else by the Stripe product id of the subscribed price (stripe_product_id), else by the plan_code metadata Checkout wrote (any plan with that code, active or not), so a subscription created on a price that a later sync archived, or on a plan whose code was changed, is stored; contracts.Update carries ProductID and PlanCode, SubscriptionArgs carries product_id and plan_code, and job arguments still hold no e-mail, name or address."
+    - "WR-06: Service.SyncSubscription retrieves outside any transaction, then in one short transaction re-reads the row FOR UPDATE, writes only the gateway-owned columns (stripe_status, cancel_at_period_end, both period bounds, canceled_at, ended_at, trial_ends_at, stripe_customer_id) and, when the gateway implements contracts.SubscriptionRetriever, subscription_plan_id from the retrieved price (same resolution as Apply), under the same per-subscription advisory lock as the job; a plan switch, subscriber or customer id written between the caller's load and the sync is never overwritten, and no event fires (PHP reconcile parity)."
+    - "D-21 is amended for ordering by this gap closure (user decision 2026-10-14 on verification human item 1): out-of-order events no longer behave as on PHP; the READMEs' 'Out-of-order events' lines and 18.1-CONTEXT.md § Amendments say so. D-21's other defaults (cancel_at_period_end mapping, both payload shapes, latest subscription with has_access) are unchanged."
+    - "Compatibility: no route, event name, table, column, config key or customer API response shape changes; contracts.Gateway keeps its eight methods (the retriever is an optional interface); pgsub still links no stripe-go (D-06); every commit keeps go vet and go test ./... green in both plugin repositories, existing assertions that encoded the replaced behaviour are adapted in the same commit and named in the SUMMARY, and nothing is pushed or tagged (release is plan 09)."

+## Phase Goal
+
+ROADMAP Goal (not in user-story format; no story is invented, as in plans 01 to 06): the generic core of `Golem15.PaymentGatewaySubscriptions` and pgstripe's subscription gateway and webhook run on SummerCMS, and a consuming application's subscription flow works as it does on PHP.
+
+This plan's slice (gap closure 1 of 3, wave 1): the webhook and sync state findings of `18.1-REVIEW.md`: CR-01 (stale event snapshots, including the deletion retry), WR-04 (subscriptions on archived prices or renamed plans never stored) and WR-06 (SyncSubscription's stale full-row save without a plan refresh). The user decided on 2026-10-14 (verification human item 1) to fix these rather than accept them as PHP parity.
+
+## Decision amendment: D-21 superseded for event ordering
+
+D-21 said "out-of-order events behave as PHP does". The user's 2026-10-14 decision on verification human item 1 supersedes that clause for ordering: the job now applies the state Stripe holds (re-retrieved), serialised per subscription, and a deletion that arrives before its subscription is stored is retried. This is a deliberate departure from PHP behaviour, recorded here, in both READMEs and in `18.1-CONTEXT.md` § Amendments (Task 3). D-21's other defaults stay: PHP's `cancel_at_period_end` mapping, both payload shapes, and `GET /subscription` answering the latest subscription with `has_access` and `in_grace_period`.
+
+## Decisions taken in this plan (Claude's discretion)
+
+- **Re-retrieve, not a watermark.** Stripe's `event.created` has one-second resolution, and Checkout emits `created` and `updated` within the same second, so a watermark cannot order exactly the race the review describes. Re-retrieving needs no schema change, so no migration is added.
+- **Retrieval outside the transaction, serialised by a session-level advisory lock.** `pg_advisory_lock` runs on a connection pinned with GORM's `DB.Connection`; no transaction is open during the Stripe call. The claim-first transaction runs on the same connection after the call. The lock is released in a deferred unlock that ignores request cancellation, and closing the connection releases it too.
+- **Stripe 404 falls back to the snapshot.** A signed event names a subscription of the same account and mode, so a 404 is near-impossible. If it happens, the PHP behaviour (apply the snapshot) is the floor, so no event is silently dropped. Existing tests whose Stripe fake holds no object for an event keep this path, and the host helper sets the fake's state to each event's object (Task 1) so the host flow runs the fresh path.
+- **Plan fallback order: price, product, plan_code.** The product id survives repricing and code changes (`upsertProduct` updates one product per plan), and the `plan_code` metadata covers a plan whose product id was never stored.
+- **Optional interface, not a ninth Gateway method.** `contracts.SubscriptionRetriever` keeps the published `contracts.Gateway` interface unchanged for other implementers (D-05 Google Play stays possible).
+
+## Artifacts this phase produces (this plan)
+
+- `../sm-paymentgatewaysubscriptions-plugin/classes/lock.go` (new): `WithSessionLock(ctx context.Context, db *gorm.DB, key string, fn func(conn *gorm.DB) error) error`, `SubscriptionLockKey(gatewaySubscriptionID string) string`, unexported const `lockKeyPrefix`.
+- `../sm-paymentgatewaysubscriptions-plugin/classes/apply.go`: `ErrSubscriptionNotStored`; unexported `resolvePlan(db *gorm.DB, u contracts.Update) (*models.SubscriptionPlan, string, error)`, `planForProduct`, `planByCode`; `Apply` and `ApplyDeleted` use them.
+- `../sm-paymentgatewaysubscriptions-plugin/classes/service.go`: `SyncSubscription` rewritten (retrieve outside the transaction, lock, gateway-owned columns, plan refresh); unexported `gatewayFields`.
+- `../sm-paymentgatewaysubscriptions-plugin/contracts/gateway.go`: `Update.ProductID`, `Update.PlanCode`, interface `SubscriptionRetriever` with `RetrieveSubscription(ctx context.Context, subscriptionID string) (Update, error)`.
+- `../sm-pgstripe-plugin/subscriptions/gateway.go`: `ErrSubscriptionMissing`, `(*Gateway).RetrieveSubscription`, `SyncSubscription` built on it, the assertion `var _ contracts.SubscriptionRetriever = (*Gateway)(nil)`, `MetadataPlanCode` used for the checkout metadata key.
+- `../sm-pgstripe-plugin/subscriptions/decode.go`: const `MetadataPlanCode`; `subscriptionItem.Price.Product`; `SubscriptionArgs.ProductID` (`product_id`) and `SubscriptionArgs.PlanCode` (`plan_code`) filled by `args()`.
+- `../sm-pgstripe-plugin/subscriptions/job.go`: `work` re-retrieves created and updated events under the subscription lock, runs deletions under it, maps `ProductID` and `PlanCode` in `update()`; unexported `applySubscription`.
+- `../sm-pgstripe-plugin/subscriptions/fresh_state_smoke_test.go` (new): `TestFreshStateSmoke` with subtests `stale_updated_after_active`, `missing_at_stripe_applies_snapshot`, `deleted_before_created`, `repriced_plan_by_product`, `sync_keeps_plan_switch`.
+- Adapted tests: `host_test.go` (`subEvent` stores the event's object in the fake), `decode_test.go` (`TestJobArgsMinimal` key list gains `plan_code` and `product_id`), pgsub `core_smoke_test.go` (`event_diff` expects `ErrSubscriptionNotStored` for an unknown deletion).
+- Docs: both READMEs (features, API reference, deviations), `COVERAGE.md` (subscriptions.retrieve row), `18.1-CONTEXT.md` (D-21 amendment).
+
+<objective>
+Close CR-01, WR-04 and WR-06: the webhook job and the reconcile sync apply the state Stripe holds, serialised per subscription, never a stale snapshot over newer data; a deletion that arrives before its subscription is stored is retried; a billed subscription on an archived price or a renamed plan is stored; and a sync never overwrites columns it does not own. D-21 is superseded for ordering per the user's 2026-10-14 decision.
+
+Purpose: money-relevant correctness of access (a paid customer must not lose access, a canceled one must not regain it) before any production cutover.
+Output: commits in sm-paymentgatewaysubscriptions-plugin and sm-pgstripe-plugin (code, adapted tests, READMEs), one planning-docs commit in summercms.go (COVERAGE, CONTEXT amendment). New unit-test coverage is plan 09; this plan carries one Postgres smoke test (`TestFreshStateSmoke`).

+  <action>Implements CR-01's preferred fix (re-retrieve in the job) and supersedes D-21 for ordering per the user's 2026-10-14 decision; D-11's claim-first transaction is kept.
+
+pgsub (commit first): create classes/lock.go with `WithSessionLock(ctx, db, key, fn)`: it pins one connection with `db.WithContext(ctx).Connection`, runs `SELECT pg_advisory_lock(hashtextextended(?, 0))` with key on it, calls fn with that connection, and in a deferred step runs `SELECT pg_advisory_unlock(hashtextextended(?, 0))` on the same connection through `context.WithoutCancel(ctx)`, logging (ids only) an unlock error at Error. A nil db or empty key is an error. Add `SubscriptionLockKey(gatewaySubscriptionID)` returning `lockKeyPrefix + "subscription:" + id` with `lockKeyPrefix = "golem15.paymentgatewaysubscriptions:"`. Package doc of the file: a session-level lock, never held inside a transaction, so a provider call may run under it.
+
+pgstripe gateway.go: add `ErrSubscriptionMissing` (Stripe answered that the subscription does not exist). Add exported `RetrieveSubscription(ctx, subscriptionID) (contracts.Update, error)`: an empty id is an error; it builds the client with `g.client(ctx)`, calls `sc.V1Subscriptions.Retrieve(ctx, id, nil)`, maps a `*stripe.Error` with HTTP status 404 or code `resource_missing` to an error wrapping ErrSubscriptionMissing (logged through `g.failed`), requires `remote.LastResponse.RawJSON`, decodes it with `decodeSubscription` and returns `obj.args().update()` (the job's own mapping, so the subscriber and app metadata come from Stripe). Keep `SyncSubscription` unchanged in this task.
+
+pgstripe job.go: in `work`, before the existing transaction, handle created and updated events whose Subscription has an id through a new unexported `applySubscription(ctx, svc, db, args)`: (1) `svc.EventProcessed(ctx, db, args.EventID)`; an error is returned, true logs "event already processed" at Info and returns nil without a Stripe call; (2) when the app tag differs from `metadataApp` (same condition as today) fall through to the existing transaction path, which claims and skips with the marker kept (STRIPE-007) and makes no Stripe call; (3) otherwise run `classes.WithSessionLock(ctx, db, classes.SubscriptionLockKey(s.ID), fn)` where fn calls `NewGateway(p.app).RetrieveSubscription(ctx, s.ID)`; on an error wrapping ErrSubscriptionMissing it logs at Warn ("Stripe has no such subscription; the event snapshot is applied", event id and subscription id) and uses `s.update()`; on any other error it returns the error (no marker, River retries); then it runs `lagoon.Transaction(ctx, conn, ...)` that claims the marker with `svc.ClaimEvent` (not claimed: return nil) and calls `svc.Apply(ctx, tx, u)`. The job's Error log on failure stays as it is. Deleted and invoice events keep today's path in this task.
+
+Test adaptation (same pgstripe commit, behaviour-preserving): in host_test.go `subEvent`, store the event's object in the fake with `e.fake.setSubscription(...)` before returning the body, so Stripe holds the state each delivered event describes (real Stripe semantics) and the host flow exercises the fresh path; run the full subscriptions suite and adapt only assertions the fresh path legitimately changes, naming each in the SUMMARY.
+
+Smoke (allowed in a non-final plan): create subscriptions/fresh_state_smoke_test.go, package subscriptions_test, `TestFreshStateSmoke` on `bootSubscriptionsHost`: subtest `stale_updated_after_active` activates a subscription (`e.activate`), sets the fake's object to active, delivers a customer.subscription.updated whose snapshot says incomplete (built with `eventBody` and `subscriptionObject` directly, not `subEvent`, so the fake keeps active), and asserts the row stays active and no subscription event fires; subtest `missing_at_stripe_applies_snapshot` delivers a created event for an id the fake does not hold and asserts the row is stored with the snapshot's status. Later tasks add subtests.
+
+README (pgstripe subscriptions, same commit): Features "Job" describes the fresh retrieval, the lock and the snapshot fallback on a 404; API reference lists `RetrieveSubscription` and `ErrSubscriptionMissing`. pgsub README API reference lists `WithSessionLock` and `SubscriptionLockKey` in the pgsub commit.</action>

+
+pgsub (commit first): contracts/gateway.go `Update` gains `ProductID string` (the gateway's product of the subscribed price; used to find the plan when the price id is unknown) and `PlanCode string` (the plan code the checkout recorded; the last fallback). classes/apply.go: add `ErrSubscriptionNotStored` ("the gateway subscription has no stored row yet"); `ApplyDeleted` on an unknown row keeps its Warn log and returns an error wrapping ErrSubscriptionNotStored that names the gateway subscription id (no row change, no event), and its doc says the caller retries. Replace the plan lookup in `Apply` with unexported `resolvePlan(db, u)` returning the plan and how it matched: `planForPrice` (unchanged, exact), else `planForProduct(db, u.ProductID)` (`stripe_product_id = ?`, lowest id), else `planByCode(db, u.PlanCode)` (`code = ?`, active or not); an empty id or code skips its step. A match by product or code logs at Warn with the subscription id, the unknown price id and the matched plan code; no match keeps today's behaviour (the stored plan when the row has one, else the "no plan holds price id" error naming the price, product and code). Update the doc comments of Apply and ApplyDeleted. Adapt core_smoke_test.go `event_diff`: the `sub_never_seen` deletion now expects `errors.Is(err, classes.ErrSubscriptionNotStored)`, a nil row and no event (the transaction helper must not fail the test on that expected error; use the existing `env.txErr` form). README (pgsub): API reference lists `ErrSubscriptionNotStored`, `Update.ProductID`, `Update.PlanCode`; Usage or Features states the plan resolution order.
+
+pgstripe (second commit): decode.go adds `MetadataPlanCode = "plan_code"` to the metadata consts, `Product pgstripe.ExpandableID` (json `product`) on `subscriptionItem.Price`, and `SubscriptionArgs.ProductID` (json `product_id,omitempty`) and `SubscriptionArgs.PlanCode` (json `plan_code,omitempty`) filled by `args()` from the first item's price product and `Metadata[MetadataPlanCode]`; the doc of WebhookJobArgs lists the two new keys (ids and a code, no personal data). job.go `update()` maps both onto `contracts.Update`. gateway.go writes the checkout metadata key through `MetadataPlanCode` (same value). Move deleted events under the subscription lock: in `work`, a deleted event with an id runs `classes.WithSessionLock(ctx, db, classes.SubscriptionLockKey(s.ID), ...)` around the existing claim-first transaction on the pinned connection, so it serialises with created and updated jobs; an ErrSubscriptionNotStored from ApplyDeleted rolls the marker back and is returned (River retries; the job's Error log names it). Adapt decode_test.go `TestJobArgsMinimal`: the subscription key list gains `plan_code` and `product_id` (still no e-mail, name or address key). Extend `TestFreshStateSmoke` with `deleted_before_created` (a deleted event for a subscription with no row returns an error from Work and leaves no marker; after a created event whose fake state is canceled is applied, the retried deletion succeeds, the row is canceled, has_access is false and activated never fired) and `repriced_plan_by_product` (a plan whose stripe_prices no longer hold the subscription's price but whose stripe_product_id equals the price's product stores the subscription on that plan).

+
+pgsub (commit first): contracts/gateway.go adds the optional interface `SubscriptionRetriever` with `RetrieveSubscription(ctx context.Context, subscriptionID string) (Update, error)` (doc: a Gateway may implement it to report the provider's current state as an Update; the service uses it to sync and to map the plan; it never writes the database). classes/service.go rewrites `SyncSubscription(ctx, sub)` with the same signature: a nil sub or a sub without a gateway subscription id is an error; the gateway resolves as today; everything runs inside `WithSessionLock(ctx, s.db, SubscriptionLockKey(id), ...)` so a sync never interleaves with a webhook job of the same subscription. Inside the lock, outside any transaction: when the gateway implements SubscriptionRetriever, call it and keep the Update; otherwise copy the caller's row, call `gw.SyncSubscription(ctx, &copy)` and derive an Update from the copy's gateway-owned fields (no plan refresh on that path). Then one `lagoon.Transaction` on the pinned connection: re-read the row by primary key FOR UPDATE (none is an error naming the id), apply the gateway-owned fields through unexported `gatewayFields(row, u)` (stripe_status only when it is one of models.Statuses and non-empty; cancel_at_period_end as reported; current_period_start, current_period_end, canceled_at, ended_at, trial_ends_at only when non-nil, never cleared; stripe_customer_id only when non-empty), set subscription_plan_id from `resolvePlan` when the retriever path resolved a plan, save with `Select` of exactly those columns plus updated_at (never a full-row Save), load the plan with `loadPlan`, and copy the saved row into the caller's `*sub`. No event fires (PHP reconcile parity). Update the doc comment and the README: API reference lists `SubscriptionRetriever`; "Differences from PHP" replaces "Out-of-order gateway events behave as on PHP: the last applied state wins" with the new rule (the job applies the provider's current state serialised per subscription; a deletion before its subscription is stored is retried; superseding D-21 for ordering by the 2026-10-14 decision) and adds that a sync writes only the gateway-owned columns and refreshes the plan.
+
+pgstripe (second commit): gateway.go asserts `var _ contracts.SubscriptionRetriever = (*Gateway)(nil)` and reimplements `SyncSubscription` on top of `RetrieveSubscription` (same in-memory fields as today, so the contract method keeps its behaviour). Extend `TestFreshStateSmoke` with `sync_keeps_plan_switch`: load a subscription, then switch its plan and customer id in the database (as Apply would), set the fake's object to a new status on the second plan's price, call `svc.SyncSubscription` with the stale loaded copy, and assert the row has the fake's status, the second plan, the switched customer id, and that the caller's copy now matches the row; no event fires. README (subscriptions): "Sync" describes the retriever path; "Deviations from PHP" replaces the "Out-of-order events" line with the fresh-state rule, the 404 snapshot fallback, the deletion retry and the D-21 amendment.
+
+Planning docs (summercms.go, own commit, staged by path): COVERAGE.md row "subscriptions.retrieve (syncSubscription / reconcile)" keeps INTEGRATE and its reason names the webhook job's fresh-state retrieval (CR-01, plan 18.1-07). 18.1-CONTEXT.md § Amendments gains one bullet: "D-21 amendment (2026-10-14, gap closure 18.1-07, user decision on verification human item 1): out-of-order events no longer behave as PHP; created and updated events apply the subscription Stripe holds, serialised per subscription, and a deletion before its subscription is stored is retried. D-21's other defaults are unchanged." Do not edit plans 01 to 06.</action>

+## Trust Boundaries
+
+| Boundary | Description |
+|----------|-------------|
+| Stripe webhook to the River job | signed events arrive out of order and are retried concurrently |
+| job to Stripe API | the job now reads the authoritative subscription before writing |
+| reconcile caller to the subscriptions row | a sync must not overwrite state written by the webhook job |
+
+## STRIDE Threat Register
+
+| Threat ID | Category | Component | Severity | Disposition | Mitigation Plan |
+|-----------|----------|-----------|----------|-------------|-----------------|
+| T-18.1-35 | Tampering | pgstripe `work` / pgsub `Apply`: an older event snapshot overwrites newer state (CR-01) | high | mitigate | created and updated apply `RetrieveSubscription`'s current state; `WithSessionLock` on `SubscriptionLockKey` serialises jobs of one subscription; the claim-first transaction stays (Task 1) |
+| T-18.1-36 | Elevation of Privilege | `ApplyDeleted` on an unknown row commits the marker, a later created grants access (CR-01 sequence 2) | high | mitigate | `ErrSubscriptionNotStored` rolls the marker back and River retries; the retried created event stores Stripe's canceled state (Task 2) |
+| T-18.1-37 | Repudiation | a billed subscription is never stored after a reprice or code change (WR-04) | medium | mitigate | plan resolution by price, then product, then plan_code; an unresolved plan still fails loudly with the ids (Task 2) |
+| T-18.1-38 | Tampering | `SyncSubscription` lost update (WR-06) | medium | mitigate | row re-read FOR UPDATE, `Select` of the gateway-owned columns only, same subscription lock as the job (Task 3) |
+| T-18.1-39 | Denial of Service | a leaked session advisory lock or a slow Stripe retrieve stalls jobs of one subscription | low | mitigate | the lock is keyed per subscription, released in a deferred unlock that ignores cancellation and by connection close; a failed retrieve returns the error so River retries with backoff |
+| T-18.1-40 | Information Disclosure | job arguments gain `product_id` and `plan_code` | low | accept | ids and a plan code only, no personal data; `TestJobArgsMinimal`'s fixed key list is extended and still refuses e-mail, name and address keys |
+| T-18.1-SC | Tampering | npm/pip/cargo installs | high | mitigate | no package is installed by this plan; GORM `Connection` and Postgres advisory locks are already available |

+# Phase 18.1 Plan 07: Webhook and sync state gap closure (CR-01, WR-04, WR-06) Summary
+
+**The Stripe webhook job now applies the subscription state Stripe holds, which it re-retrieves outside any transaction under a per-subscription Postgres session advisory lock. The claim-first transaction is unchanged. A deletion that arrives before its subscription is stored is retried. Plans resolve by price, then product, then plan code. SyncSubscription writes only the gateway-owned columns of a locked, re-read row and refreshes the plan.**
+
+## Performance
+
+- **Duration:** 20 min
+- **Started:** 2026-10-16T10:04:33Z
+- **Completed:** 2026-10-16T10:24:17Z
+- **Tasks:** 3 of 3
+- **Files modified:** 18 (8 pgsub, 8 pgstripe, 2 planning docs)
+
+## Accomplishments
+
+- **CR-01, fresh state.** For `customer.subscription.created` and `.updated` the job:
+  1. checks the marker (`EventProcessed`) before any Stripe call;
+  2. sends another application's event to the claim-first path (marker kept, no Stripe call);
+  3. otherwise takes `classes.WithSessionLock(ctx, db, classes.SubscriptionLockKey(id), ...)`, calls `Gateway.RetrieveSubscription` with no transaction open, then claims and applies in a `lagoon.Transaction` on the same pinned connection.
+  - A Stripe 404 or `resource_missing` (`ErrSubscriptionMissing`) applies the event snapshot with a Warn log.
+  - Any other retrieval error returns with no marker, so River retries.
+- **CR-01, deletion retry.** `ApplyDeleted` on an unknown row returns an error wrapping `classes.ErrSubscriptionNotStored`, with no change and no event. Deleted events run under the same per-subscription lock. The marker rolls back and River retries. The late `created` event stores Stripe's `canceled`, so `activated` never fires.
+- **WR-04.** `contracts.Update` gains `ProductID` and `PlanCode`; `SubscriptionArgs` gains `product_id` and `plan_code` (ids and a code only, no PII). `Apply` resolves the plan in this order:
+  1. exact price id;
+  2. `stripe_product_id`;
+  3. plan code, active or not.
+
+  A match by product or code logs at Warn. When nothing matches, the error names the price, product and code.
+- **WR-06.** `contracts.SubscriptionRetriever` (optional; the Gateway contract keeps its eight methods). `Service.SyncSubscription`:
+  - runs under the same lock and asks the gateway outside any transaction;
+  - re-reads the row `FOR UPDATE` and saves with `Select` of only the gateway-owned columns, plus `subscription_plan_id` from the retrieved price on the retriever path;
+  - copies the saved row into the caller's `*sub` and fires no events.
+- **D-21 amendment** recorded in both READMEs ("Differences from PHP" and "Deviations from PHP"), `18.1-CONTEXT.md` § Amendments and `COVERAGE.md`.

+
+## Adapted existing assertions
+
+| Repo / file | Test | Old expectation | New expectation | Why |
+|---|---|---|---|---|
+| pgstripe `subscriptions/host_test.go` | helper `subEvent` (all users of it) | the fake held no object for a delivered event | `subEvent` stores the event's object in the fake, so the host flow runs the fresh path | real Stripe holds the state it sends (plan Task 1) |
+| pgstripe `subscriptions/host_test.go` | `TestHostSubscriptionFlow/pre_basil_periods` | the pre-basil event built with `eventBody` was applied as is | the fake is seeded with the same pre-basil object before delivery; the period assertion is unchanged | the job now applies what Stripe holds; without the seed the fake held the activation's periods |
+| pgsub `core_smoke_test.go` | `TestSubscriptionsCoreSmoke/event_diff` (`sub_never_seen` deletion) | `env.tx` with nil error, nil row, no event | `env.txErr` returns an error wrapping `classes.ErrSubscriptionNotStored` naming the id; nil row, no event | CR-01 sequence 2 |
+| pgsub `apply_events_test.go` | `TestApplyEvents` (deleted matrix, unknown ids) | `sub_never_seen` and `""` both nil, nil | `sub_never_seen` returns `ErrSubscriptionNotStored`; `""` stays nil, nil; neither changes a row or fires an event | CR-01 sequence 2 |
+| pgstripe `subscriptions/job_test.go` | `TestSubscriptionJob/stripe_007 skips keep the marker and fire nothing` | `evt_job_del_unknown` returned nil and kept 1 marker | Work returns `ErrSubscriptionNotStored` and leaves 0 markers (moved out of the skip loop); doc comment updated | CR-01 sequence 2 |
+| pgstripe `subscriptions/decode_test.go` | `TestJobArgsMinimal` | subscription key list without `plan_code`/`product_id`; `plan_code` in the leak list for every type | key list gains `plan_code` and `product_id` (fixture price gains `product`); `plan_code` stays a leak for invoice types only; values asserted | WR-04 (plan Task 2) |
+| pgstripe `subscriptions/decode_test.go` | `TestDecodeSubscription` (basil args) | whole-struct `want` without `ProductID`/`PlanCode` | fixture price carries an expanded `product` object; `want` gains `ProductID: "prod_pro"`, `PlanCode: "pro"` | WR-04 (the fixture already had `plan_code` metadata) |
+| pgsub `service_api_test.go` | `TestServiceAPI/sync subscription saves the gateway state without events` | rows without a gateway subscription id were synced | rows get `sub_probe_sync` / `sub_probe_sync_fail`; adds checks that the caller's copy is refreshed, the probe saw no open transaction, and a row without an id is refused | WR-06: the new SyncSubscription needs the id it locks and reports on |
+
+## Smoke results (Docker host available)
+
+- Task 1: `TestFreshStateSmoke`, `TestHostSubscriptionFlow`, `TestSubscriptionJob`, `TestStripeSubscriptionReliability`, `TestSubscriptionWebhookSmoke`: 5 top-level PASS.
+- Task 2: full pgsub suite green; `TestFreshStateSmoke`, `TestHostSubscriptionFlow`, `TestSubscriptionJob`, `TestStripeSubscriptionReliability`: 4 top-level PASS.
+- Task 3: full Postgres suites green in both repositories, and `bash scripts/check-phase18.1.sh plugins` passed. As an extra check, `bash scripts/check-phase18.1.sh postgres` also passed (14 pgsub, 4 + 7 pgstripe, 3 cabana required suites).
+- `TestFreshStateSmoke` subtests, all PASS:
+  - `stale_updated_after_active`
+  - `stale_update_after_cancel_no_reactivated`
+  - `missing_at_stripe_applies_snapshot`
+  - `deleted_before_created`
+  - `repriced_plan_by_product`
+  - `plan_by_code_fallback`
+  - `sync_keeps_plan_switch`
+- The host flow ran 17 events through the fresh retrieval and 1 through the snapshot fallback (`checkout_activation`, whose event is built without fake state).
+- D-06: `go list -deps` of pgsub contains no stripe-go.
+
+## D-21 amendment text (18.1-CONTEXT.md § Amendments)
+
+> **D-21 amendment (2026-10-14, gap closure 18.1-07, user decision on verification human item 1):** out-of-order events no longer behave as PHP; created and updated events apply the subscription Stripe holds, serialised per subscription, and a deletion before its subscription is stored is retried. D-21's other defaults are unchanged.
+
+## Decisions Made
+
+- The plan's discretionary choices were followed: re-retrieve rather than a watermark, a session lock outside any transaction, the 404 snapshot fallback, the price/product/code order, and an optional interface rather than a ninth Gateway method.
+- A failed `pg_advisory_lock` or `pg_advisory_unlock` (or an unlock reporting that the lock was not held) marks the pinned `*sql.Conn` bad (`Raw` returning `driver.ErrBadConn`). database/sql then closes it instead of returning it to the pool, and closing the session releases any lock it holds. Without this, a lock granted at the moment of a cancellation could leak onto a pooled connection.
+- On a gateway without `SubscriptionRetriever`, `SyncSubscription` uses only the gateway-owned fields that `Gateway.SyncSubscription` changed on a detached copy. When the cancel flag is unchanged, the re-read row keeps its own value. Copying every field would write the caller's stale values, which is WR-06 again.
+- `RetrieveSubscription` refuses an answer whose `id` differs from the requested one, and `SyncSubscription` refuses an Update naming another subscription.
+
+## Deviations from Plan
+
+### Auto-fixed Issues
+
+**1. [Rule 3 - Blocking] Adapted assertions in test files outside the plan's file list**
+- **Found during:** Tasks 2 and 3
+- **Issue:** `apply_events_test.go`, `job_test.go` and `service_api_test.go` encoded the replaced behaviour: nil, nil for an unknown deletion, and a sync of a row without a gateway subscription id. `TestDecodeSubscription` compares the whole args struct.
+- **Fix:** adapted in the same commits, listed in the table above.
+- **Files modified:** pgsub `apply_events_test.go`, `service_api_test.go`; pgstripe `subscriptions/job_test.go`, `subscriptions/decode_test.go` (the last is in the plan list, but only for `TestJobArgsMinimal`).
+- **Committed in:** `89c5f1b`, `2a86d7c`, `9d83b78`
+
+**2. [Rule 2 - Missing critical] Connection discard on a failed lock or unlock**
+- **Found during:** Task 1
+- **Issue:** GORM's `Connection` returns the pinned connection to the pool on close. A session lock still held there would block every later job of that subscription.
+- **Fix:** `discardConn` marks it bad (`driver.ErrBadConn`) so it is closed (threat T-18.1-39).
+- **Files modified:** `classes/lock.go`
+- **Committed in:** `9165dd8`
+
+**3. [Rule 1 - Bug] Non-retriever sync path would rewrite stale values**
+- **Found during:** Task 3
+- **Issue:** the plan's "derive an Update from the copy's gateway-owned fields" would write the caller's stale periods, cancel flag and customer id whenever the gateway left them untouched.
+- **Fix:** only fields that changed relative to the caller's load are used, on a deep copy of the pointer fields.
+- **Files modified:** `classes/service.go`
+- **Committed in:** `9d83b78`
+
+**4. [Scope, additive] Extra smoke subtests**
+- `stale_update_after_cancel_no_reactivated` (CR-01 sequence 3, a must-have truth) and `plan_by_code_fallback` (the WR-04 code step) were added next to the five named subtests.
+- Each subtest name appears only in its `t.Run`, so the acceptance greps print the exact line counts. The doc comment uses prose names.
+
+**5. [Acceptance grep] Comment-only follow-up commit `0484d4f`**
+- `grep -n "contracts.SubscriptionRetriever" gateway.go` must print one line, and the `SyncSubscription` doc comment repeated the name. The comment was reworded.
+
+---
+
+**Total deviations:** 3 auto-fixed (1 blocking, 1 missing critical, 1 bug) plus 2 additive or cosmetic. **Impact:** all correctness-preserving; no public route, event, table, column, config key or response shape changed.
+
+## Issues Encountered
+
+- Cross-repository ordering: pgstripe resolves pgsub through a `replace` onto the working tree, and the plan orders pgsub first. So between the pgsub Task 2 commit (`89c5f1b`) and the pgstripe Task 2 commit (`2a86d7c`), pgstripe's checked-in `TestSubscriptionJob` still expected the old unknown-deletion answer. The pgstripe change was prepared and tested before the pgsub commit, and the two were committed back to back. Every pair of commits that belong together is green.
+
+## Observations for later plans
+
+- While the job holds the lock it holds one pinned connection, plus a short second one for `LoadSettings` inside `RetrieveSubscription`. lagoon sets no pool cap and conga runs 4 workers per queue, so this cannot starve by default. An application that caps `MaxOpenConns` at or below its worker count could. Plan 09 may want a note or test.
+- `checkout_activation` in `TestHostSubscriptionFlow` still exercises the snapshot fallback (no fake state). That is deliberate; the fresh path is covered by the `subEvent`-based subtests and `TestFreshStateSmoke`.
+
+## Threat Flags
+
+None. No new endpoint, auth path or trust-boundary schema change. The new job argument keys (`product_id`, `plan_code`) are T-18.1-40 (accepted), and `TestJobArgsMinimal` pins them.
+
+## User Setup Required
+
+None.
+
+## Next Phase Readiness
+
+- Ready for 18.1-08 (gap closure 2 of 3) and 18.1-09, which owns the unit coverage of the lock, `resolvePlan`, `gatewayFields` and `RetrieveSubscription`, and the release and tags.
+- No blockers.

+*Phase: 18.1-payment-gateway-subscriptions*

No currency is ever billed at another currency's price."

+
+## Phase Goal
+
+ROADMAP Goal (not in user-story format; no story is invented, as in plans 01 to 07): the generic core of `Golem15.PaymentGatewaySubscriptions` and pgstripe's subscription gateway and webhook run on SummerCMS, and a consuming application's subscription flow works as it does on PHP.
+
+This plan's slice (gap closure 2 of 3, wave 2, after 18.1-07 because both change `classes/service.go`, `classes/lock.go` and the Stripe gateway): checkout, admin sync and layer findings of `18.1-REVIEW.md`: CR-02 (cross-currency charge), WR-02 (duplicate Stripe customers), WR-03 (double subscriptions), WR-01 (plan sync inside the bulk transaction) and WR-07 (buttons stuck after Back). The user decided on 2026-10-14 to fix them.
+
+## Decisions taken in this plan (Claude's discretion)
+
+- **WR-01 needs a framework addition.** cabana runs every bulk action inside a transaction that holds `FOR UPDATE` locks on the selected rows. Saving a plan's Stripe ids "in a short transaction of its own" from inside `Run` would wait on that lock until it times out. A Stripe call made outside the lock is therefore impossible from plugin code. The plan adds one opt-in field, `pact.AdminBulkAction.Detached` (`json:"-"`, so neither the list schema nor the OpenAPI changes). It ships in framework tag v0.1.27 at plan 09's release. This is the "framework feature is missing" case of CLAUDE.md. The alternative was rejected: keep the bulk sync inside the transaction and only make product creation self-healing. That still holds the lock and the open transaction across Stripe calls, which is exactly what the review flags. Reversibility: costly, flagged on Task 3.
+- **The yen is dropped rather than special-cased.** `money.FromMinor` and the customer API's `amount_minor` assume two decimals. Supporting zero-decimal currencies would change the Money JSON contract. Refusing the yen at checkout (422) is the smaller, non-breaking change, and the README records it as a deviation from PHP's list.
+- **CheckoutPriceID is new, StripePriceIDFor stays.** `StripePriceIDFor` is PHP's `getStripePriceId` (lenient fallback), and other readers may rely on it. Checkouts use the strict method. A `stripe_prices` map with at least one entry decides alone. An empty or missing map means the plan was never synced, so a hand-entered `stripe_price_id` serves only the plan's own currency.
+- **WR-03 serialisation without a transaction across Stripe.** Local rows appear only after the webhook, so a database lock alone cannot stop two sessions opened before payment. Three measures together cover the race:
+  - a session-level advisory lock per subscriber, the helper from plan 07, which serialises the check, the customer and the session;
+  - a Stripe idempotency key over the subscriber, plan, currency and parameters, which returns the same session to a parallel or repeated request;
+  - the non-terminal status guard, which refuses once a subscription exists.
+  `Service.Checkout` keeps PHP's unguarded behaviour for app routes that do their own check; `CheckoutGuarded` is the customer-facing entry point.
+- **Idempotency keys have a 10-minute window and a parameter hash.** Stripe replays a stored response, including a 500, for 24 hours. The window bounds a replayed failure, and the hash avoids an `idempotency_error` when an application's metadata differs between calls.
+- **"Send past_due and unpaid users to the portal"** is met by the existing 409 and the layer's `PgManageSubscriptionButton`, which shows on that 409. The copy loses the word "active" so it fits those users too.
+
+## Artifacts this phase produces (this plan)
+
+- `../sm-paymentgatewaysubscriptions-plugin/models/subscription_plan.go`: `(SubscriptionPlan) CheckoutPriceID(currency string) string`.
+- `../sm-paymentgatewaysubscriptions-plugin/models/subscription.go`: `TerminalStatuses`, `ScopeOpen(db *gorm.DB) *gorm.DB`.
+- `../sm-paymentgatewaysubscriptions-plugin/classes/lock.go`: `SubscriberLockKey(alias string, id uint) string`.
+- `../sm-paymentgatewaysubscriptions-plugin/classes/service.go`: `ErrAlreadySubscribed`, `(*Service).Open`, `(*Service).CheckoutGuarded`; `ensureCustomer` stores through a cancellation-free context and uses the stored winner; `SyncPlan` with a nil tx saves through a cancellation-free context.
+- `../sm-paymentgatewaysubscriptions-plugin/classes/user_subscribable.go`: first-write-wins `SetCustomerID` with re-read.
+- `../sm-paymentgatewaysubscriptions-plugin/contracts/subscriber.go`: `SetCustomerID` doc (an implementation may keep a stored id).
+- `../sm-paymentgatewaysubscriptions-plugin/api/subscription.go` and `api/json.go`: the 422 gateway-price gate, the 409 on any open subscription through `Open` and `CheckoutGuarded`, the updated contract comment.
+- `../sm-paymentgatewaysubscriptions-plugin/controllers/subscriptionplans.go`: `sync_to_stripe` with `Detached: true`; `syncOne(ctx, svc, plan, tally)` saves through `SyncPlan(ctx, nil, plan)`; `runSyncAll` without a transaction wrapper.
+- `../sm-pgstripe-plugin/subscriptions/gateway.go`: `CreateCheckoutSession` on `CheckoutPriceID`, the yen removed from `supportedCurrencies`, field `Gateway.Now func() time.Time`, unexported `idempotencyWindow` and `idempotencyKey(kind string, parts ...string) string`, keys on the customer create and the session create.
+- `modules/pact/capabilities.go`: field `AdminBulkAction.Detached bool` (`json:"-"`). `modules/cabana/crud.go`: the detached branch of `CRUDService.BulkAction`, unexported `loadScoped` with `lockScoped` kept as its locking wrapper.
+- `../vue-paymentgateway-layer/app/utils/subscribe.ts`: `PageRestoreTarget`, `watchPageRestore(target, handler): () => void`, `SubscribeFlow.restore()`, `ManageFlow.restore()`, a guarded `location.assign`.
+- Smoke subtests: `TestCustomerAPISmoke/currency_without_gateway_price_is_422`, `TestCustomerAPISmoke/past_due_is_409`.
+- Adapted tests: `gateway_test.go` subtests "the checkout currency picks the price" (no fallback across currencies) and "supported currencies" (the yen moves to the unsupported list); the customer API smoke's `pro` plan gets `stripe_prices` for the currencies it checks out in.
+- Docs: pgsub README, pgstripe subscriptions README, `modules/pact/README.md`, `modules/cabana/README.md`, `docs/backend/admin-controllers.md`, the layer README, `COVERAGE.md`.
+
+<objective>
+Close CR-02, WR-02, WR-03, WR-01 and WR-07:
+- a checkout charges only the price of the currency it shows;
+- concurrent or repeated checkouts create neither a second Stripe customer nor a second session or subscription;
+- any open subscription blocks a new checkout;
+- the admin plan sync never calls Stripe inside a transaction or loses the ids Stripe created;
+- the layer's buttons recover after the browser's Back button.
+
+Purpose: these money-relevant and user-facing defects must be fixed before any application cuts over to this plugin.
+Output: commits in summercms.go (framework Detached, docs), sm-paymentgatewaysubscriptions-plugin, sm-pgstripe-plugin and vue-paymentgateway-layer, plus a planning-docs commit (COVERAGE). New unit-test coverage is plan 09. This plan carries two smoke subtests and the adaptations of existing tests whose expectations the fixes change.

+Repositories: summercms.go (framework), ../sm-paymentgatewaysubscriptions-plugin (pgsub), ../sm-pgstripe-plugin (pgstripe), ../vue-paymentgateway-layer (layer). The plugins `replace` summercms with ../summercms.go and pgstripe replaces pgsub, so local builds see uncommitted siblings. Commit order inside a task: framework, then pgsub, then pgstripe, then the layer; one logical change per commit; stage by explicit path; no co-author tags; never push or tag. Several sessions work in summercms.go: before touching a framework file, `git status --porcelain -- <file>` must show no foreign edit; if it does, stop and report instead of staging, stashing or overwriting.

+  <action>Implements CR-02 on the D-13 customer API and the D-15 plan-sync price map; response shapes stay as D-13's confirmed contract.
+
+pgsub (commit first): models/subscription_plan.go adds `CheckoutPriceID(currency string) string`. The currency is trimmed and lower-cased. When `StripePrices` is valid with at least one entry, it answers that map's entry for the currency or "" (no fallback). Otherwise it answers `*StripePriceID` only when the currency equals the plan's `Currency` case-insensitively and the id is non-empty, else "". The doc comment of `StripePriceIDFor` says it is PHP's lenient getStripePriceId and that checkouts use CheckoutPriceID. In api/subscription.go `Checkout`, after the existing `priced` and `SupportsCurrency` check and before the URL check, `plan.CheckoutPriceID(currency) == ""` answers the same 422 `{"currency": [msgCurrencyInvalid]}` without calling the gateway. Update the handler's doc comment and the api/json.go contract comment: a 422 also covers a currency the plan has no gateway price in, and no currency is billed at another currency's price. customer_api_smoke_test.go:
+- the `pro` plan gets `stripe_prices` entries for pln and eur, so the existing `checkout` subtest (EUR) still passes;
+- a new subtest `currency_without_gateway_price_is_422` creates a plan with currency_prices pln and gbp and stripe_prices pln and usd, then asserts that a gbp checkout answers 422 with the currency error and makes no gateway call, and that a pln checkout answers 200 with the gateway called in pln.
+
+README (pgsub): Customer API table row of checkout (422 text); API reference adds `CheckoutPriceID`.
+
+pgstripe (second commit), gateway.go:
+- `CreateCheckoutSession` takes its price from `plan.CheckoutPriceID(currency)`; "" stays `ErrNoPriceForCurrency` (wrapping, naming plan and currency, no Stripe call). Its comments describe the strict rule by concept and do not name the lenient model method. Update the sentinel's doc: no price of its own in the currency, no fallback across currencies.
+- Drop the zero-decimal Japanese yen code from `supportedCurrencies`. `SupportsCurrency`'s doc says the list is PHP's minus the yen, because the core's money display assumes two decimals.
+
+Adapt gateway_test.go in the same commit:
+- "the checkout currency picks the price": a currency the gold plan's map lacks now expects ErrNoPriceForCurrency and no Stripe call, instead of the default price id;
+- "supported currencies": the yen moves to the refused list.
+
+Run the subscriptions suite and adapt any other assertion that relied on the fallback, naming each in the SUMMARY. README (subscriptions):
+- Features "Checkout" names CheckoutPriceID and the missing fallback;
+- the "Currencies" line drops the yen;
+- "Deviations from PHP" gains two lines: no cross-currency fallback (PHP getStripePriceId fell back to stripe_price_id), and the yen is not supported.</action>

+  <action>Implements WR-02 and WR-03 for the D-13 customer API; D-08/D-09 (the user subscriber writes only users.stripe_customer_id) hold.
+
+pgsub (commit first):
+- models/subscription.go adds `TerminalStatuses` (canceled, incomplete_expired) and `ScopeOpen` (stripe_status NOT IN TerminalStatuses).
+- classes/lock.go adds `SubscriberLockKey(alias, id)` built from the same prefix as SubscriptionLockKey, with "subscriber:", the alias, ":" and the decimal id.
+- classes/service.go adds `ErrAlreadySubscribed`, `Open(ctx, alias, id)` and `CheckoutGuarded(ctx, sub, plan, successURL, cancelURL, o)`:
+  - `Open` returns the latest subscription with ScopeOpen and its Plan loaded, ordered like Latest, or nil.
+  - `CheckoutGuarded` runs inside `WithSessionLock(ctx, s.db, SubscriberLockKey(sub.MorphAlias(), sub.Key()), ...)`. Inside the lock it calls `Open`; an open subscription returns an error wrapping ErrAlreadySubscribed that names the row id and status. It re-resolves the subscriber with `s.Subscriber` (so a customer id stored by a concurrent request is seen), then delegates to `s.Checkout`. No transaction is held across the gateway calls; the lock is session-level.
+  - `Checkout` itself is unchanged (PHP createCheckoutSession has no guard). Its doc points customer-facing callers to CheckoutGuarded.
+- `ensureCustomer`:
+  - stores the id in its short transaction as today, now opened with `context.WithoutCancel(ctx)`, so a customer Stripe already created is recorded even when the request was cancelled;
+  - after the store, reads `sub.CustomerID()`. When it differs from the created id, it logs at Warn that a concurrent checkout stored another customer, with both ids (ids only), and continues with the stored one.
+- classes/user_subscribable.go `SetCustomerID`:
+  - runs `UPDATE users SET stripe_customer_id = ? WHERE id = ? AND (stripe_customer_id IS NULL OR stripe_customer_id = '')`;
+  - with one row affected it remembers id;
+  - with none it re-reads stripe_customer_id of that id with a raw query (no soft-delete filter): no row is ErrSubscriberNotFound, a stored non-empty id is remembered and nil returned, an empty one is an error.
+  - It still writes no other column.
+- contracts/subscriber.go: the `SetCustomerID` doc says an implementation may keep an id that is already stored (first write wins), and CustomerID then answers the stored id.
+- api/subscription.go `Checkout` answers 409 errAlreadySubscribed in two places:
+  - its early check (same position) uses `d.svc.Open` instead of `d.svc.Active`;
+  - after the subscriber is resolved it calls `d.svc.CheckoutGuarded`, and an error wrapping `classes.ErrAlreadySubscribed` answers 409.
+  - Other errors keep `writeGatewayError`.
+- api/json.go contract comment: 409 for any subscription that is not canceled or incomplete_expired (a past_due or unpaid user manages it in the billing portal).
+- customer_api_smoke_test.go adds subtest `past_due_is_409`: a past_due row of the user answers 409 "Already subscribed" and the gateway is not called. Adapt any existing assertion that expects an overwrite of a stored customer id, naming it in the SUMMARY.
+
+README (pgsub):
+- API reference lists Open, CheckoutGuarded, ErrAlreadySubscribed, ScopeOpen, TerminalStatuses and SubscriberLockKey;
+- the Customer API table's 409 row;
+- Usage: customer-facing checkouts call CheckoutGuarded;
+- the built-in user subscriber keeps the first stored customer id.
+
+pgstripe (second commit), gateway.go:
+- adds the field `Now func() time.Time` (nil means time.Now), an unexported `idempotencyWindow` of 10 minutes, and an unexported `idempotencyKey(kind string, parts ...string) string`. The key is "pgsub-", the kind, "-", the decimal window number (Unix seconds of Now divided by the window), "-", and the first 32 hex characters of the SHA-256 (crypto/sha256, encoding/hex) of the parts joined with a NUL byte.
+- `GetOrCreateCustomer` sets the key on its CustomerCreateParams: kind "customer"; parts are the alias, the id, the e-mail, the name and the sorted metadata pairs.
+- `CreateCheckoutSession` sets the key on its CheckoutSessionCreateParams: kind "checkout"; parts are the alias, the id, the customer id, the price id, the success and cancel URLs, and the sorted metadata pairs.
+- Keys are never logged.
+
+README (subscriptions): the Customer and Checkout features describe the keys and the window; API reference lists `Gateway.Now`.
+
+Planning docs (summercms.go, own commit): COVERAGE.md rows "customers.create with subscriber metadata" and "checkout.sessions.create (mode subscription)" keep INTEGRATE; their reasons name the idempotency key (WR-02 and WR-03, plan 18.1-08).</action>

+  <action>Implements WR-01 for the D-15 plan sync. The framework addition is the only way to keep Stripe calls out of cabana's bulk transaction (see "Decisions taken in this plan").
+
+Framework (summercms.go, commit first, after the precondition check):
+- modules/pact/capabilities.go: `AdminBulkAction` gains `Detached bool` tagged `json:"-"`. Its doc: Run then runs outside the framework transaction; the selected records are loaded through the list scope without row locks; the context carries no write transaction; Run opens the short transactions it needs; an action that calls an external service sets it so that no transaction or row lock is held across the call; what such an action saved before a later failure stays saved. The type's doc paragraph mentions the field.
+- modules/cabana/crud.go `BulkAction`: after the existing name, id and model checks, an action with Detached set takes a new branch that opens no transaction. It loads the rows with a new unexported `loadScoped(ctx, db, cc, proto, ids, lock bool)`; `lockScoped` becomes a call of it with lock true, so the locked path is byte-identical. The branch loads on `s.DB` with lock false and applies the same rules:
+  - no row: affected 0 without running the action;
+  - fewer rows than ids: the existing partial-selection 409;
+  - Run is called with the locale context but no write transaction;
+  - an error goes through `actionFailure`;
+  - the message is translated with `translateKey` as on the locked path.
+  The non-detached path is unchanged.
+- Docs in the same commit, naming no application, provider or subscription:
+  - docs/backend/admin-controllers.md: the bulk route list gains a bullet for `Detached: true` (loaded through the same scope without row locks, `cabana.TxFromContext` reports no transaction, Run opens its own short transactions, the use case of external calls, earlier saves stay on a later failure);
+  - modules/pact/README.md: the `pact.AdminBulkAction` table row mentions the field;
+  - modules/cabana/README.md: the bulk actions bullet mentions the detached variant.
+
+pgsub (second commit):
+- controllers/subscriptionplans.go:
+  - The sync_to_stripe bulk action sets `Detached: true`.
+  - `runSyncSelected` no longer reads the framework transaction from the context. It type-checks the records as today and syncs each plan.
+  - `syncOne` drops its transaction parameter and calls `svc.SyncPlan(ctx, nil, plan)`.
+  - `runSyncAll` iterates the active plans and calls `syncOne` directly, with no transaction wrapper around it. A failed save comes back from SyncPlan as an error and becomes a failure line, never a synced count.
+  - Update the doc comments of AdminBulkActions, AdminActions, syncOne and both run functions: no transaction is held across the Stripe calls, and each plan's ids are saved right after its calls.
+  - Remove imports that become unused.
+- classes/service.go `SyncPlan`: a nil tx saves through `s.db` with `context.WithoutCancel(ctx)`, so the ids Stripe created are recorded although the admin's request was cancelled. A non-nil tx keeps today's behaviour. The doc says request paths pass nil, and the save stays the `Select` of stripe_product_id, stripe_prices, stripe_price_id and updated_at.
+- README (pgsub) Admin section: both sync actions run outside any transaction, and each plan's ids are saved right after its Stripe calls.

+app/utils/subscribe.ts:
+- Add an exported interface `PageRestoreTarget` with `addEventListener` and `removeEventListener` for a `pageshow` listener. Add `watchPageRestore(target, handler)`, which returns a remover:
+  - it registers a pageshow listener that calls handler only when the event's `persisted` is true (a back/forward-cache restore);
+  - the remover unregisters it;
+  - an undefined or null target (server rendering) returns a no-op remover.
+- `SubscribeFlow` and `ManageFlow` gain `restore(): void`, which sets busy and redirecting false and error null.
+- In both flows, the `deps.location.assign(url)` call moves inside a try block. A throw resets busy and redirecting and sets error to pg.subscriptions.error.generic.
+- Update the header comment: the redirect keeps the button busy until the page is left, and a back/forward-cache restore re-enables it.
+
+Components:
+- SubscribeButton.vue and ManageSubscriptionButton.vue keep a remover. `onMounted` sets it from `watchPageRestore(window, () => flow.restore())`; `onBeforeUnmount` calls it.
+- MySubscription.vue does the same for its manage flow and also calls `refresh()` on a restore, so the panel shows what the portal changed.
+- Update each header comment.

+## Trust Boundaries
+
+| Boundary | Description |
+|----------|-------------|
+| browser to customer API | the authenticated user chooses plan and currency; the server decides the price |
+| customer API and admin to Stripe | Checkout, customer and plan-sync calls create billable objects |
+| admin bulk action to the database | the framework's bulk transaction and its row locks |
+| browser history to the layer | back/forward-cache restores JavaScript state |

+## STRIDE Threat Register
+
+| Threat ID | Category | Component | Severity | Disposition | Mitigation Plan |
+|-----------|----------|-----------|----------|-------------|-----------------|
+| T-18.1-41 | Tampering | `api.Checkout` / `Gateway.CreateCheckoutSession`: a currency without its own price is billed at another currency's price (CR-02) | high | mitigate | `CheckoutPriceID` with no cross-currency fallback in both the API 422 gate and the gateway; the yen refused (Task 1) |
+| T-18.1-42 | Tampering | `ensureCustomer` / `SetCustomerID`: concurrent checkouts create two Stripe customers and the last write wins (WR-02) | medium | mitigate | idempotency key per subscriber and parameters; first-write-wins conditional UPDATE with re-read; cancellation-free store (Task 2) |
+| T-18.1-43 | Tampering | `api.Checkout`: a user with a past_due, unpaid, incomplete or paused subscription, or two parallel tabs, gets a second billing subscription (WR-03) | high | mitigate | 409 for any open status; `CheckoutGuarded` re-checks under `SubscriberLockKey`; idempotent session create (Task 2) |
+| T-18.1-44 | Denial of Service | plan sync holds the bulk transaction and plan row locks across Stripe calls; a rollback loses created ids (WR-01) | medium | mitigate | `Detached` bulk action; per-plan short saves through a cancellation-free context; toolbar sync without a transaction wrapper (Task 3) |
+| T-18.1-45 | Elevation of Privilege | a detached bulk action bypasses the list scope, the partial-selection rule or the permissions | medium | mitigate | the detached branch loads through the same `ListExtendQuery` scope with the same empty and 409 rules; permissions are checked before BulkAction as today; the locked path is unchanged (13 TestBulkAction passes) |
+| T-18.1-46 | Denial of Service | an idempotent replay returns a stored Stripe failure or rejects changed parameters | low | mitigate | 10-minute window bounds a replayed failure; the parameter hash gives changed parameters a new key; keys are never logged |
+| T-18.1-47 | Denial of Service | buttons stay disabled after a back/forward-cache restore (WR-07) | low | mitigate | `watchPageRestore` plus `restore()` in all three components; a throwing navigation resets the state (Task 4) |
+| T-18.1-SC | Tampering | npm/pip/cargo installs | high | mitigate | no package is installed: crypto/sha256 and encoding/hex are stdlib, the layer adds no dependency (package.json and pnpm-lock.yaml unchanged) |

+# Phase 18.1 Plan 08: Checkout, admin sync and layer gap closure (CR-02, WR-01, WR-02, WR-03, WR-07) Summary
+
+**A checkout now bills only the plan's own Stripe price in the requested currency. The customer API answers the existing 422, and the gateway answers ErrNoPriceForCurrency, for a currency without its own price. Customer and Checkout Session creates carry Stripe idempotency keys, and the user's customer id is first-write-wins. A guarded checkout refuses any open subscription under a per-subscriber advisory lock. Plan sync runs outside any transaction through a new opt-in framework field, `pact.AdminBulkAction.Detached`. The layer's buttons recover after Back from Stripe.**

+- **CR-02.** `SubscriptionPlan.CheckoutPriceID(currency)` returns the plan's own price for the currency and never falls back across currencies:
+  - a `stripe_prices` map with at least one entry decides alone;
+  - without such a map, `stripe_price_id` serves only the plan's own currency.
+
+  The customer API checkout answers the existing 422 `{"currency": [...]}` without a gateway call when the price is empty. The Stripe gateway's `CreateCheckoutSession` uses the same method, so it answers `ErrNoPriceForCurrency` without a Stripe call. `StripePriceIDFor` keeps PHP's lenient fallback for other readers. The yen is no longer in `SupportsCurrency`.
+- **WR-02.**
+  - The Stripe customer create carries an idempotency key: `pgsub-customer-<window>-<32 hex>`. The hash covers the alias, id, e-mail, name and sorted metadata, and the window is 10 minutes (`Gateway.Now`, unexported `idempotencyKey`, `idempotencyWindow`).
+  - The user subscriber writes `stripe_customer_id` only when none is stored. Otherwise it re-reads the stored id and adopts it.
+  - `ensureCustomer` stores the id through `context.WithoutCancel`. When the stored id differs from the one it created, it logs both ids at Warn and continues with the stored one.
+  - The `SetCustomerID` contract doc allows first-write-wins.
+- **WR-03.**
+  - `models.TerminalStatuses` and `models.ScopeOpen` define an open subscription; `Service.Open` returns the latest one.
+  - `Service.CheckoutGuarded` runs under `WithSessionLock(..., SubscriberLockKey(alias, id), ...)`. It refuses with `ErrAlreadySubscribed` (naming the row id and status) when an open subscription exists, re-resolves the subscriber, then delegates to `Checkout`, which stays unguarded as in PHP.
+  - The customer API's early check uses `Open`. The handler calls `CheckoutGuarded`, and an `ErrAlreadySubscribed` from it is also a 409.
+  - The session create carries an idempotency key `pgsub-checkout-...` over the subscriber, customer, price, both URLs and the metadata.
+- **WR-01 (framework).**
+  - `pact.AdminBulkAction.Detached bool` is tagged `json:"-"`, so neither the list schema nor the OpenAPI changes.
+  - `cabana.CRUDService.BulkAction` has a detached branch. It opens no transaction, loads the rows through the list scope with the new unexported `loadScoped(..., lock=false)`, and keeps the empty, partial-selection 409, `actionFailure` and `translateKey` rules.
+  - `lockScoped` is now `loadScoped(..., true)`, so the locked path builds the same query.
+  - Documented in `docs/backend/admin-controllers.md` and the pact and cabana READMEs.
+- **WR-01 (pgsub).**
+  - `sync_to_stripe` sets `Detached: true` and no longer reads the framework transaction.
+  - `syncOne(ctx, svc, plan, tally)` calls `SyncPlan(ctx, nil, plan)`.
+  - `runSyncAll` opens no transaction, and a failed save is a failure line.
+  - `SyncPlan` with a nil tx saves through `s.db` with `context.WithoutCancel`.
+- **WR-07.**
+  - `watchPageRestore(target, handler)` and `PageRestoreTarget`: a `pageshow` listener that fires only when `persisted` is true. It returns a remover, and a nil target (server rendering) gets a no-op remover.
+  - `SubscribeFlow.restore()` and `ManageFlow.restore()`.
+  - A `location.assign` that throws resets the state with `pg.subscriptions.error.generic`.
+  - The three components register the watch in `onMounted` and remove it in `onBeforeUnmount`. `PgMySubscription` also calls `refresh()` on a restore.
+  - The `already_subscribed` copy drops "active" in en and pl.

+## Task Commits
+
+sm-paymentgatewaysubscriptions-plugin (pgsub):
+1. Task 1 (tracer): `f88a210` feat(18.1-08): checkout bills only the plan's own price in its currency (CR-02)
+2. Task 2: `5d8ded1` feat(18.1-08): one customer and one checkout per subscriber; any open subscription blocks checkout (WR-02, WR-03)
+3. Task 3: `b6738d3` feat(18.1-08): plan sync holds no transaction or row lock across Stripe calls (WR-01)
+
+sm-pgstripe-plugin (pgstripe):
+1. Task 1 (tracer): `38ad591` feat(18.1-08): Stripe checkout refuses a currency without its own price; yen dropped (CR-02)
+2. Task 2: `c9bd953` feat(18.1-08): idempotency keys on the Stripe customer and Checkout Session creates (WR-02, WR-03)
+
+summercms.go:
+- Task 2 (planning docs): `f217c73` docs(18.1-08): idempotency keys and the strict checkout price in COVERAGE
+- Task 3 (framework, committed before the pgsub Task 3 commit): `fc2a397` feat(18.1-08): detached admin bulk actions run outside the framework transaction
+
+vue-paymentgateway-layer:
+- Task 4: `34cf926` feat(18.1-08): subscribe and manage buttons recover after Back from Stripe; 409 copy fits any open subscription (WR-07, WR-03)
+
+Nothing was pushed or tagged (release is plan 09).
+
+**Framework tag needed:** the plugins use `pact.AdminBulkAction.Detached`, which exists only in summercms.go `fc2a397`. They still `require summercms v0.1.26` and build only through the `replace ../summercms.go`. Framework tag **v0.1.27** and the require bump (plan 09) are needed before the plugins can be built from git without the replace.
+
+## Adapted existing assertions
+
+| Repo / file | Test | Old expectation | New expectation | Why |
+|---|---|---|---|---|
+| pgsub `customer_api_smoke_test.go` | `TestCustomerAPISmoke` plan setup (`pro`) | `pro` had no gateway prices; the EUR checkout reached the fake gateway | `pro` gets `stripe_prices` `{pln: price_pro_pln, eur: price_pro_eur}`, so the `checkout` (EUR) and `gateway_error_is_502` (PLN) subtests still reach the gateway | CR-02: the 422 gate now needs a gateway price per currency (named in the plan) |
+| pgsub `customer_api_authz_test.go` | `TestCustomerAPIAuthz` plan setup (`authz`) | plan created with no price id; "other's checkout" answered 200 | plan created with `stripe_price_id` `price_authz_pln` in its own currency (PLN); the assertions are unchanged | CR-02: without its own gateway price the checkout is now 422 |
+| pgsub `fixture_plugin_test.go` | `fakeGateway.SupportsCurrency` (all users) | usd, eur, pln | usd, eur, pln, gbp (gbp is in the real gateway's list) | without gbp the new `currency_without_gateway_price_is_422` subtest would be refused by `SupportsCurrency` before the new gate and prove nothing; no test expected gbp to be refused |
+| pgstripe `subscriptions/gateway_test.go` | `TestSubscriptionGateway/the checkout currency picks the price` | `eur` on the gold plan (map pln, usd; default `price_gold_default`) billed `price_gold_default` | `eur` answers `ErrNoPriceForCurrency` naming `"eur"` with no Stripe call; PLN, pln and usd unchanged | CR-02 (named in the plan) |
+| pgstripe `subscriptions/gateway_test.go` | `TestSubscriptionGateway/supported currencies` | `jpy` supported | `jpy` and `JPY` in the refused list | yen dropped (named in the plan) |
+
+No other assertion in either suite relied on the cross-currency fallback, and none expected a stored customer id to be overwritten (`TestUserSubscribable` checked only a first write).
+
+## Smoke results (Docker host available)
+
+- **Task 1 (tracer gate re-run, auto):**
+  - pgsub `TestCustomerAPISmoke`, `TestCustomerAPIAuthz`, `TestServiceAPI`: 3 top-level PASS.
+  - pgstripe `TestSubscriptionGateway`, `TestHostSubscriptionFlow`: 2 top-level PASS.
+  - Both full suites green.
+  - D-06: `go list -deps` of pgsub contains no stripe-go.
+- **Task 2:**
+  - full pgsub Postgres suite green;
+  - pgstripe `TestSubscriptionGateway`, `TestHostSubscriptionFlow`, `TestFreshStateSmoke`: 3 top-level PASS, and the full pgstripe suite green.
+  - `TestCustomerAPISmoke/past_due_is_409` and `TestCustomerAPISmoke/currency_without_gateway_price_is_422` pass.
+- **Task 3:**
+  - framework `go vet ./...`, `go test -short ./...`, `TestDocsTree`, `docs:build --check` ("no problems found") and `check-admin-openapi.sh --check` all pass;
+  - `TestBulkAction*`: 14 top-level PASS (see deviation 3);
+  - pgsub `TestAdminSyncActions`, `TestAdminPlansSmoke`, `TestServiceAPI`, `TestSubscriptionsCoreSmoke`: 4 top-level PASS;
+  - full pgsub and pgstripe suites green after the change.
+- **Task 4:** `pnpm test`: 105 pass, `# fail 0`. `bash scripts/check-phase18.1.sh layers` passed (36 `subscriptions:` tests, minimum 36). `tsc` reports nothing for `app/utils/subscribe.ts`, and passing `window` as a `PageRestoreTarget` type-checks. `package.json` and `pnpm-lock.yaml` are unchanged against v0.2.0.
+
+## Decisions Made
+
+- The plan's discretionary choices were followed:
+  - CheckoutPriceID next to the lenient StripePriceIDFor;
+  - the yen dropped;
+  - lock plus idempotency key plus status guard for WR-03;
+  - a 10-minute window and a parameter hash for the keys;
+  - the opt-in `Detached` field for WR-01.
+- `CheckoutGuarded` runs `Open`, `Subscriber` and `Checkout` on the service pool while the lock pins its connection. As in plan 07, a request holds the pinned connection plus one short second connection at a time, and the Stripe client's `LoadSettings` takes a third short one. lagoon sets no pool cap, so this is fine by default.
+- The detached cabana branch passes its error through `localizeForbidden`, as the locked path does through `s.transaction`, so a `ForbiddenError` from a detached `Run` is localized identically.
+- The idempotency key hashes the full checkout metadata, `user_email` included. It never leaves the process except as the Stripe header and is never logged.
+
+## Deviations from Plan
+
+### Auto-fixed Issues
+
+**1. [Rule 3 - Blocking] Adapted test fixtures outside the plan's file list**
+- **Found during:** Task 1
+- **Issue:** `TestCustomerAPIAuthz` created its plan without any gateway price, so its checkout became 422. The fake gateway refused gbp, so the new subtest could not tell the new gate apart from `SupportsCurrency`.
+- **Fix:** the authz plan gets its own-currency `stripe_price_id`, and the fake supports gbp (see the table above).
+- **Files modified:** pgsub `customer_api_authz_test.go`, `fixture_plugin_test.go`
+- **Commit:** `f88a210`
+
+**2. [Rule 2 - Missing verification, additive] Idempotency key smoke**
+- **Found during:** Task 2
+- **Issue:** the Stripe fake did not keep request headers, so nothing showed that the keys reach Stripe or behave per window.
+- **Fix:** `fakeRequest.Idempotency` records the `Idempotency-Key` header, and the new subtest `TestSubscriptionGateway/idempotency keys` checks:
+  - the format;
+  - the same key for a repeated checkout;
+  - a new key for changed parameters and for the next window;
+  - the customer key prefix.
+- **Files modified:** pgstripe `subscriptions/stripefake_test.go`, `subscriptions/gateway_test.go`
+- **Commit:** `c9bd953`
+
+**3. [Plan count] 14 framework TestBulkAction passes, not 13**
+- **Found during:** Task 3
+- **Issue:** Task 3's verify expects exactly 13 `--- PASS: TestBulkAction` lines. `-run '^TestBulkAction'` also matches the existing `TestBulkActionBodyCap` in `phase121_actions_test.go`, which a previous phase added. The plan counted only the 13 functions of `phase121_bulk_test.go`.
+- **Fix:** none needed. All 14 pass and the locked path is unchanged. Recorded here.
+
+**4. [Acceptance grep] Comment rewording in subscriptionplans.go**
+- `grep -n "Detached:"` must print one line. The `AdminBulkActions` doc comment said "is Detached:", so it was reworded to "runs detached" before the commit.
+
+---
+
+**Total deviations:** 2 auto-fixed (1 blocking, 1 additive verification) plus 2 count or cosmetic notes. **Impact:**
+- no public route, event, table, column, config key or customer API response shape changed;
+- the new refusals reuse the existing 409 and 422 bodies;
+- non-detached bulk actions behave as before;
+- `contracts.Gateway` keeps its methods.
+
+## Issues Encountered
+
+- Cross-repository ordering: pgstripe resolves pgsub through a `replace` onto the working tree. Each pgsub commit was tested together with the matching pgstripe change, then the two were committed back to back. Task 1's pgsub commit does not change `StripePriceIDFor`, so pgstripe stays green in between.
+- Task 3 order: the framework commit `fc2a397` came before the pgsub commit `b6738d3`, because pgsub uses the new field through the replace.
+
+## Known Stubs
+
+None.
+
+## Threat Flags
+
+None. No new endpoint, auth path, file access or trust-boundary schema change. The `Detached` branch keeps the list scope, the partial-selection rule and the permission checks (T-18.1-45).
+
+## User Setup Required
+
+None.
+
+## Next Phase Readiness
+
+- Ready for 18.1-09 (gap closure 3 of 3: unit coverage and release). Plan 09 should:
+  - tag framework v0.1.27 and bump the plugins' `require`;
+  - cover with unit tests `CheckoutPriceID`, `Open`/`ScopeOpen`, `CheckoutGuarded` under concurrency, first-write-wins `SetCustomerID`, the cabana detached branch, `idempotencyKey` and `watchPageRestore`/`restore()` in a mounted component;
+  - release layer 0.2.1.
+- No blockers.
+
+---
+*Phase: 18.1-payment-gateway-subscriptions*
+*Completed: 2026-10-16*
+
+## Self-Check: PASSED
+
+All 8 task commits found (pgsub f88a210 5d8ded1 b6738d3, pgstripe 38ad591 c9bd953, summercms.go f217c73 fc2a397, layer 34cf926); the key modified files exist; every acceptance criterion of Tasks 1-4 re-run and passing (Task 3 bulk count 14, see deviation 3); all three sibling trees clean; summercms.go has only the foreign STATE.md/state.json edits and untracked files of other sessions.

A failed Stripe retrieval leaves no marker and is retried. A duplicate or another application's event makes no Stripe call."

TestGatewayIdempotencyKeys covers the Idempotency-Key header on the customer and session creates: equal within a window for equal parameters, different across windows (Gateway.Now) and for different metadata.

+
+## Phase Goal
+
+ROADMAP Goal (not in user-story format; no story is invented, as in plans 01 to 08): the generic core of `Golem15.PaymentGatewaySubscriptions` and pgstripe's subscription gateway and webhook run on SummerCMS, and a consuming application's subscription flow works as it does on PHP.
+
+This plan's slice (gap closure 3 of 3, the last wave): SC-5 for the gap closure. It adds unit and Postgres tests for everything plans 07 and 08 changed (CR-01, CR-02, WR-01, WR-02, WR-03, WR-04, WR-06, WR-07), extends the fail-closed `scripts/check-phase18.1.sh`, fills the README Testing sections and the VALIDATION map, and ends with the human's release decision (D-22), mirroring plan 06.
+
+## Decisions taken in this plan (Claude's discretion)
+
+- New test files per finding group (ordering, gateway hardening, plan resolution, sync, checkout guard, detached sync, detached bulk action) rather than growing plan 06's files, so the gate names and the review findings map one to one.
+- `TestDetachedBulkAction` is named so that it does not match plan 08's `^TestBulkAction` count of 13, and that count stays meaningful.
+- The layer's component specs render on the server (no `onMounted`), so the mount and unmount wiring is asserted from the component sources and the behaviour through `watchPageRestore` and the flows.
+- Release tags (proposed on the sheet, decided by the human):
+  - framework `v0.1.27`, needed because pgsub uses `pact.AdminBulkAction.Detached`;
+  - layer `v0.2.1` with `package.json` 0.2.1;
+  - first plugin tags `v0.1.0` on pgsub and pgstripe, an option the orchestrator asked for. No plugin tag exists yet. sm-paymentgateway-plugin is untagged too, so a pgsub tag alone still needs consumers' `replace` lines (IN-08, out of scope).
+
+## Artifacts this phase produces (this plan)
+
+- `modules/cabana/bulk_detached_test.go`: `TestDetachedBulkAction`.
+- `../sm-pgstripe-plugin/subscriptions/ordering_test.go`: `TestEventOrdering` with subtests `checkout_race_updated_first`, `checkout_race_concurrent`, `deleted_before_created`, `stale_cancel_flag_no_reactivated`, `retrieve_error_retries`, `duplicate_makes_no_stripe_call`, `other_app_makes_no_stripe_call`.
+- `../sm-pgstripe-plugin/subscriptions/gateway_hardening_test.go`: `TestGatewayStrictPrice`, `TestGatewayIdempotencyKeys`, `TestRetrieveSubscription`.
+- `../sm-pgstripe-plugin/subscriptions/stripefake_test.go`: `fakeRequest` keeps the `Idempotency-Key` header; `setFailRetrieve(bool)` makes `GET /v1/subscriptions/{id}` answer 500.
+- `../sm-pgstripe-plugin/subscriptions/decode_test.go`: `TestDecodeSubscription` cases for the price's product (string and expanded) and `plan_code`.
+- `../sm-paymentgatewaysubscriptions-plugin/models/checkout_price_test.go`: `TestCheckoutPriceID`, `TestTerminalStatuses`.
+- `../sm-paymentgatewaysubscriptions-plugin/plan_resolution_test.go`: `TestPlanResolution`, `TestApplyDeletedNotStored`.
+- `../sm-paymentgatewaysubscriptions-plugin/sync_subscription_test.go`: `TestSyncSubscriptionFresh`.
+- `../sm-paymentgatewaysubscriptions-plugin/checkout_guard_test.go`: `TestCheckoutGuarded`, `TestCustomerIDFirstWriteWins`, `TestCustomerAPIGuards`.
+- `../sm-paymentgatewaysubscriptions-plugin/admin_sync_detached_test.go`: `TestAdminSyncDetached`.
+- Layer specs (names start with "subscriptions:") in `tests/subscribe.test.ts` and `tests/subscriptionComponents.test.ts`; `package.json` version 0.2.1.
+- `scripts/check-phase18.1.sh`: the new names in `PG_CABANA_TESTS`, `PGSUB_MODELS_TESTS`, `PG_PGSUB_TESTS`, `PG_PGSTRIPE_SUBS_TESTS`, `LAYER_REQUIRE`, and a raised `LAYER_PREFIX_MIN`.
+- README Testing sections (pgsub, pgstripe subscriptions, cabana, layer); `18.1-VALIDATION.md` rows for plans 07 to 09; `deferred-items.md` entries; release commits (go.mod require bumps) and the release record.
+
+<objective>
+Prove every gap-closure fix with named tests, require them in the phase gate, record them in the VALIDATION map and the README Testing sections, and publish the result only on the human's reply.
+
+Purpose: SC-5 and the project rule that unit tests are the last plan; the gate is what /msd-verify-work re-runs for the gap closure.
+Output: test commits in four repositories, the extended gate, the updated VALIDATION map, the layer version, and the release record.
+
+Execution budget: above the single-context smart zone by design, like plan 06. The project rule puts every gap-closure test in this last plan and the user fixed three plans. The mitigation is one task per repository group with a commit per task and repository, SUMMARY notes as you go, and resuming at the first uncommitted task after a reset.

+Repositories: summercms.go (gate, cabana test, VALIDATION), ../sm-paymentgatewaysubscriptions-plugin, ../sm-pgstripe-plugin, ../vue-paymentgateway-layer. Commit per repository and task; planning docs in their own commit; stage by explicit path; no co-author tags. Docker-backed suites skip under -short; run them on a Docker host (`sudo -u golem` if the socket is denied) and record NOT RUN only when no daemon answers. A test that exposes a production bug gets the fix in the owning repository as its own `fix(18.1-09): ...` commit before the test commit, and the SUMMARY lists it. Several sessions work in summercms.go: never stage or stash another session's files.

+- pgstripe test harness (package subscriptions_test): `bootSubscriptionsHost`, `subEvent`, `deliver`, `work`, `job`, `activate`, `subscription`, `recorder`, `plan`, `count` (host_test.go); fake `setSubscription`, `calls(method, path)`, `all()`, `reset()`, `record` (stripefake_test.go); `eventBody`, `subscriptionObject`, `invoiceObject` (eventbody_test.go); `TestFreshStateSmoke` from plan 07.
+- pgsub test harness (package root): `subEnv` with `plan`, `user`, `tx`, `txErr`, `count`, `capi` (harness_test.go, customer_api_smoke_test.go); the fixture `fakeGateway` (fixture_plugin_test.go); the open-transaction probe of `TestServiceAPI` (service_api_test.go, pg_stat_activity `idle in transaction`); `classes.New(classes.Options{...})` with `contracts.NewGateways()` builds a Service with a test gateway that does or does not implement `contracts.SubscriptionRetriever`.
+- Framework bulk test harness: modules/cabana/phase121_bulk_test.go (the 13 `TestBulkAction*` tests and their fixture controller).
+- Layer: `createSubscribeFlow`, `createManageFlow`, `watchPageRestore`, `restore()` (app/utils/subscribe.ts after plan 08); test helpers `renderSSR`, `loadComponent`, `stubComponent`, `fakeT` (testing/load.ts); TAP run `pnpm test`.

+    - TerminalStatuses is exactly canceled and incomplete_expired; the other six statuses are open.
+    - Plan resolution: an unknown price with a matching stripe_product_id stores that plan; with neither but a plan_code of an inactive plan stores that plan; nothing matching on a new row is an error naming the price, product and code; an existing row keeps its plan.
+    - ApplyDeleted of an unknown id: errors.Is ErrSubscriptionNotStored, nil row, no event.
+    - SyncSubscription: a retriever gateway on another plan's price moves the row to that plan; a plan switch, customer id and subscriber written after the caller's load survive; only gateway-owned columns change; no event; the legacy gateway path changes status but not the plan; a held SubscriptionLockKey on another connection delays the sync until released.
+    - CheckoutGuarded: each open status is ErrAlreadySubscribed with zero gateway calls; canceled and incomplete_expired proceed; two concurrent guarded checkouts of one subscriber never have two gateway calls in flight (an atomic in-flight counter stays at most 1) and create the customer once; two subscribers proceed in parallel.
+    - SetCustomerID: a second write keeps the first id and the subscriber answers it; a missing user is ErrSubscriberNotFound; no other users column or updated_at changes.
+    - API guards: past_due, unpaid, incomplete and paused answer 409 Already subscribed; an open subscription plus an unknown plan still answers 409 (check order unchanged); a currency without a gateway price answers 422; no gateway call in any refusal.
+    - Admin sync: neither action makes a gateway call while pg_stat_activity shows the session idle in transaction; a save that fails (a test trigger raising on UPDATE of one plan) is a failure line and not synced; ids are saved when the request context is cancelled during the gateway call.

+  <action>Per SC-5, CR-01, CR-02, WR-01, WR-02, WR-03, WR-04 and WR-06 (D-08, D-09, D-13 unchanged): write the tests against the behaviour of plans 07 and 08, fix any production bug they expose in its own commit, then extend the gate.

+  - checkout_guard_test.go: `TestCheckoutGuarded`, `TestCustomerIDFirstWriteWins` and `TestCustomerAPIGuards`, through the customer API helper;

+    - Strict price: a plan whose map lacks the currency gets ErrNoPriceForCurrency and the fake records no call although stripe_price_id is set; an unsynced plan checks out in its own currency on stripe_price_id and is refused in another; SupportsCurrency refuses the yen code and accepts usd, eur, pln, gbp, cad, aud and chf.
+    - Idempotency keys: POST /v1/customers and POST /v1/checkout/sessions carry an Idempotency-Key header starting "pgsub-customer-" and "pgsub-checkout-"; two calls with equal parameters and Gateway.Now in one window send the same key; Now plus 10 minutes sends another; different checkout metadata sends another.
+    - Retrieval: RetrieveSubscription maps status, both period shapes, price, product (string or expanded), plan_code and the subscriber metadata; a 404 wraps ErrSubscriptionMissing; a 500 is another error.
+    - Decode: TestDecodeSubscription adds the product id and plan_code mappings; job arguments still hold no e-mail, name or address.
+    - Framework: a Detached action's Run sees cabana.TxFromContext report false; during Run another connection's SELECT ... FOR UPDATE NOWAIT on a selected row succeeds; empty selection gives affected 0 without Run; a partial selection is 409; a cabana.ValidationError from Run is 422; a row Run wrote before returning that error stays written; a non-detached action of the same fixture still sees a transaction and holds the lock.

+  <action>Per SC-5, CR-01, CR-02, WR-01, WR-02, WR-03 and WR-04: tests first, bug fixes in their own commits, then the gate.
+- stripefake_test.go keeps the request's Idempotency-Key header in `fakeRequest`.

+- Framework: create modules/cabana/bulk_detached_test.go with `TestDetachedBulkAction` (Postgres) on the phase121 fixture pattern. Add a detached action to a test-only controller, so no production fixture changes. The test names no application or provider.

+- The layer README Testing section lists the new specs. A short "Changes in 0.2.1" note describes the back/forward-cache restore and the copy.
+- Gate: add the seven names to `LAYER_REQUIRE` and raise `LAYER_PREFIX_MIN` to the number of passing "subscriptions:" tests the run reports.
+- Run `PHASE181_REQUIRE_POSTGRES=1 bash scripts/check-phase18.1.sh --all` on a Docker host.

+  <read_first>.planning/phases/18.1-payment-gateway-subscriptions/18.1-06-PLAN.md (Task 5) and 18.1-06-SUMMARY.md (§ Task 5: order, commands, checks), the SUMMARYs of plans 07 and 08 and this plan's Task 4 notes (gate result, NOT RUN suites), deferred-items.md (check-git-install.sh)</read_first>
+  <action>Mirror plan 06 Task 5 (D-22): do everything automatable, print the push sheet, then stop.
+
+Per repository (summercms.go, ../sm-paymentgatewaysubscriptions-plugin, ../sm-pgstripe-plugin, ../vue-paymentgateway-layer):
+- the tree is clean for this phase's files (never stage another session's files);
+- run `git fetch origin --tags`;
+- origin has no commits the checkout lacks (otherwise stop and report);
+- list the commits that would be pushed. For summercms.go this includes any other session's commits on master, named as such.
+
+The proposed tags:
+- framework `v0.1.27` on the commit after this plan's last docs commit; it contains `pact.AdminBulkAction.Detached`;
+- layer `v0.2.1` on the commit with package.json 0.2.1;
+- optional first plugin tags `v0.1.0` on pgsub and pgstripe. No earlier tag exists; sm-paymentgateway-plugin stays untagged, so consumers still need its replace.
+
+The order (plan 06's), which keeps consumers resolvable:
+1. framework master and the v0.1.27 tag;
+2. in pgsub and in pgstripe, a separate commit raising `require git.golem15.com/golem15/summercms` to v0.1.27 (replace lines unchanged; `go mod tidy`, vet and -short green);
+3. with plugin tags: pgsub main and its tag first, then a separate pgstripe commit raising its pgsub require to v0.1.0, then pgstripe main and its tag; without them, pgsub main then pgstripe main;
+4. the layer main and v0.2.1.
+
+Record the gate result, the NOT RUN suites, and the open check-git-install.sh item: an install check of v0.2.1 needs that script fixed first.
+
+No push, tag or require bump before the reply. After the reply:
+- "push-all": the order without plugin tags;
+- "push-all-with-plugin-tags": the order with plugin tags;
+- "push-no-tags": push branches only (no tags, no require bumps);
+- "hold": nothing.
+
+Never force-push. Record the reply verbatim, every pushed hash and every tag.</action>
+  <decision>Publish the gap closure now?</decision>
+  <context>Tags are read by the Go module proxy and by applications' pinned layer dependency and cannot be moved.

+# Phase 18.1 Plan 09: Gap-closure tests, phase gate and release Summary
+
+**Named Postgres, Docker-free and TAP tests pin every fix of plans 07 and 08 (CR-01 ordering, CR-02 strict price, WR-01 detached bulk actions, WR-02/03 guard and idempotency, WR-04/06 plan resolution and fresh sync, WR-07 page restore). The phase gate requires each test by name, and the gap closure was released as framework v0.2.1, pgsub v0.1.0, pgstripe v0.1.0 and layer v0.2.1.**
+
+## Commits per repository (tasks 1 to 4)
+
+| Task | summercms.go | pgsub | pgstripe | layer |
+|------|--------------|-------|----------|-------|
+| 1 CR-01 ordering suite (tracer) | `0fc909d` gate | | `768447b` | |
+| 2 pgsub coverage | `5a446d6` gate | `2e21084` | | |
+| 3 pgstripe and framework coverage | `fa91e2a` cabana test, `b6e6736` gate | | `cc80ea7` | |
+| 4 layer coverage, 0.2.1, gate, VALIDATION | `3cb2252` gate, `48e2642` check-phase10 fix, `03b8cc2` VALIDATION and deferred items | | | `c535975` specs, `22368c5` 0.2.1 |
+
+The tracer gate after Task 1 re-ran the postgres stage end to end and it passed. A mutation check (applying the event snapshot again) turned 5 of the 7 `TestEventOrdering` subtests red.
+
+## Tests added
+
+**Framework (cabana)**
+- `TestDetachedBulkAction` (Postgres):
+  - a detached Run sees no transaction (`TxFromContext` false);
+  - another connection's `SELECT ... FOR UPDATE NOWAIT` on a selected row succeeds during Run;
+  - the empty, absent and partial-selection rules (affected 0 without Run, 409);
+  - a `ValidationError` answers 422, and a row written before it stays written;
+  - the same action without `Detached` still holds the transaction and the lock.
+
+**pgsub**
+- Docker-free: `TestCheckoutPriceID` (CR-02), `TestTerminalStatuses` (WR-03).
+- Postgres:
+  - `TestPlanResolution` (WR-04): price, stripe_prices, product, plan_code (inactive plan included), the unresolved error, an existing row keeps its plan;
+  - `TestApplyDeletedNotStored` (CR-01): the sentinel, nil row, no event;
+  - `TestSyncSubscriptionFresh` (WR-06): retriever and legacy paths, gateway-owned columns only, no events, waits for a held `SubscriptionLockKey`;
+  - `TestCheckoutGuarded` (WR-03): the six open statuses refused without a gateway call, canceled and incomplete_expired allowed, concurrent checkouts of one subscriber never overlap, two subscribers in parallel, one customer;
+  - `TestCustomerIDFirstWriteWins` (WR-02);
+  - `TestCustomerAPIGuards` (WR-03, CR-02): 409 for past_due, unpaid, incomplete and paused with the check order unchanged, 422 for a currency without a price;
+  - `TestAdminSyncDetached` (WR-01): no gateway call while the session is idle in transaction, a failed save is a failure line, ids saved after the request context was cancelled.
+
+**pgstripe**
+- `TestEventOrdering` (Postgres, CR-01). Subtests:
+  - `checkout_race_updated_first`
+  - `checkout_race_concurrent`
+  - `deleted_before_created`
+  - `stale_cancel_flag_no_reactivated`
+  - `retrieve_error_retries`
+  - `duplicate_makes_no_stripe_call`
+  - `other_app_makes_no_stripe_call`
+- Gateway tests (Postgres, for the settings):
+  - `TestGatewayStrictPrice` (CR-02);
+  - `TestGatewayIdempotencyKeys` (WR-02, WR-03);
+  - `TestRetrieveSubscription` (CR-01, WR-06).
+- `TestDecodeSubscription` gained the price's product (string and expanded) and `plan_code`. Job arguments still hold no personal data.
+- Fake: `setFailRetrieve(bool)`, and `fakeRequest` now keeps the `Idempotency-Key` header.
+
+**Layer**
+- Seven new `subscriptions:` specs, which raises the count from 36 to 43:
+  - a persisted pageshow restores the subscribe flow;
+  - a non-persisted pageshow changes nothing;
+  - `watchPageRestore`'s remover and its server no-op;
+  - a throwing navigation re-enables the button;
+  - the manage flow restores;
+  - the components' mount and unmount wiring;
+  - the already-subscribed copy in en and pl.
+- `package.json` is 0.2.1. `pnpm-lock.yaml` is unchanged.
+
+## Gate result
+
+The Task 5 sheet run of `PHASE181_REQUIRE_POSTGRES=1 bash scripts/check-phase18.1.sh --all` (clean trees, then `--all`) printed `final-push-sheet-ok`:
+
+| Stage | Result |
+|-------|--------|
+| self-test | PASS |
+| go | 5 required framework tests |
+| plugins | pgsub models 5, contracts 1, root 5; pgstripe root 4, subscriptions 3; vet and `-short` green |
+| admin | vue-tsc; vitest 1429 tests in 93 files |
+| layers | 112 TAP tests, 0 failures; 43 named `subscriptions:` (minimum 43) |
+| docs | TestDocsTree, docs:build, OpenAPI check, dist check, phase 10 hygiene |
+| postgres | framework 4; pgsub 21; pgstripe root 4, subscriptions 12 |
+
+No suite was NOT RUN.
+
+## VALIDATION
+
+`18.1-VALIDATION.md` stays `status: validated`, `nyquist_compliant: true` and `wave_0_complete: true`, revalidated 2026-10-16. It has one row per task of plans 07, 08 and 09. The manual-only rows remain:
+- a live test-mode checkout, now also watching created and updated in either order;
+- the portal `cancel_at` check;
+- the browser pass, now including Back from Checkout.
+
+## Task 5: release decision
+
+**Reply (verbatim):** "push-all-with-plugin-tags, v0.2.1"
+
+The plan proposed framework tag `v0.1.27`. Since the plan was written, `v0.1.27` and `v0.2.0` were created on origin by other sessions, so the framework tag is `v0.2.1`. Tags are immovable, so the existing tags are left untouched. The plugin requires are raised to `v0.2.1` accordingly.
+
+**Push sheet.** Every repository was 0 commits behind its origin after `git fetch origin --tags`. Unpushed commits:
+- summercms.go master: 27 ahead before this SUMMARY.
+  - This phase's commits: plans 07 to 09.
+  - Other sessions' committed work, approved for this push: quick-261016-0fm (admin theme and locale preferences, the dist rebuild for v0.2.1), the closing docs of quick-261015-w7f (summercms.io deployed on v0.2.0), and the fast task "summercms.io Alpha 0.2 copy". (Correction made after the release: an earlier version of this line also named `9921768` docs(19.3-05). That commit was already on origin as `v0.1.27`.)
+- pgsub main: 7 ahead (plans 07 to 09).
+- pgstripe main: 8 ahead (plans 07 to 09).
+- layer main: 3 ahead (plans 08 and 09).
+
+**Order** (plan 06's order, with plugin tags):
+1. framework master, then annotated `v0.2.1` on this SUMMARY's commit;
+2. pgsub: require bump to summercms `v0.2.1` (its own commit), main, annotated `v0.1.0`;
+3. pgstripe: require bump to summercms `v0.2.1` and pgsub `v0.1.0` (its own commit), main, annotated `v0.1.0`;
+4. layer: main, annotated `v0.2.1` on `22368c5`.
+
+Replace lines stay in both plugins. Nothing is force-pushed. The pushed hashes and tag objects are recorded in the release record below, which is added after the pushes.
+
+### Release record
+
+This is what was done, in the order of the push sheet. Nothing was force-pushed. Every repository was 0 commits behind its origin right before its push (`git fetch origin --tags`, then `rev-list --count HEAD..origin/<branch>`).
+
+**Framework**
+- master pushed: `f3e8a98..f64ae79`. `f64ae79` is this SUMMARY's commit.
+- Annotated tag `v0.2.1` created on `f64ae79` (tag object `f067801`) and pushed. `v0.1.27` and `v0.2.0` are untouched.
+
+**pgsub**
+- Commit `41b68f6` raises the require to `git.golem15.com/golem15/summercms v0.2.1`; the replace onto `../summercms.go` is unchanged.
+- `go mod tidy` added the framework's indirect dependencies since v0.1.26: aws-sdk-go-v2 (S3), go-redis, otter, google/wire, go.uber.org/atomic. This is +24 lines in each of go.mod and go.sum, matching the framework's own go.mod; no direct dependency was added.
+- vet and the `-short` tests pass.
+- main pushed: `472b75b..41b68f6`.
+- Annotated tag `v0.1.0` created on `41b68f6` (tag object `8b6a1f0`) and pushed.
+
+**pgstripe**
+- Commit `2a427fd` raises the requires to summercms `v0.2.1` and sm-paymentgatewaysubscriptions-plugin `v0.1.0`; the replace lines are unchanged.
+- tidy added the same indirect dependencies as in pgsub. vet and `-short` pass.
+- main pushed: `baf3c55..2a427fd`.
+- Annotated tag `v0.1.0` created on `2a427fd` (tag object `da39829`) and pushed.
+
+**Layer**
+- main pushed: `30046f5..22368c5`.
+- Annotated tag `v0.2.1` created on `22368c5` (tag object `b7a6fe7`, package.json 0.2.1) and pushed.
+
+No GOPROXY or GOPRIVATE resolution was needed during tidy, because the replace lines resolve the framework and pgsub locally.
+
+**Check:** after the pushes, each local branch equals its origin branch:
+
+| Repository | Branch | Hash | Tag (`ls-remote ^{}`) |
+|------------|--------|------|-----------------------|
+| summercms.go | master | `f64ae79`, before the later docs commits, which are pushed afterwards | `v0.2.1` → `f64ae79` |
+| pgsub | main | `41b68f6` | `v0.1.0` → `41b68f6` |
+| pgstripe | main | `2a427fd` | `v0.1.0` → `2a427fd` |
+| layer | main | `22368c5` | `v0.2.1` → `22368c5` |
+
+`grep "summercms v0.2.1"` finds a line in both plugin go.mod files, and `grep "sm-paymentgatewaysubscriptions-plugin v0.1.0"` finds one in pgstripe's go.mod.
+
+**Open item:** the layer's `scripts/check-git-install.sh` still targets `vue-journal-layer`, so an install check of layer `v0.2.1` needs that script fixed first. See `deferred-items.md`.
+
+## Decisions Made
+
+- Release per the reply `push-all-with-plugin-tags, v0.2.1`. The framework tag is `v0.2.1` instead of `v0.1.27`, because `v0.1.27` and `v0.2.0` already exist on origin.
+- New test files per finding group, so gate names map one to one to review findings.
+- The layer component specs render on the server, so the mount and unmount wiring is asserted from the component sources.
+
+## Deviations from Plan
+
+### Auto-fixed Issues
+
+**1. [Rule 3 - Blocking] The phase 10 hygiene allow-list missed the admin theme and locale cache**
+- **Found during:** Task 4 (`check-phase18.1.sh docs` failed).
+- **Issue:** `usePreferences.ts` from quick task 261016-0fm caches the theme and locale codes in localStorage. That is an accepted threat of that task (T-261016-0fm-08), but the `check-phase10.sh` hygiene allow-list was not updated, so the docs stage failed. Tokens stay forbidden.
+- **Fix:** the allow-list now accepts the two preference keys.
+- **Committed in:** `48e2642`.
+
+### Adaptations
+
+1. **The fixture `fakeGateway` gained an `onSync` hook** (pgsub `fixture_plugin_test.go`). `TestAdminSyncDetached` uses it as the open-transaction probe at the moment of the gateway call.
+2. **`TestDetachedBulkAction` uses test-only actions on the existing roster fixture**, through its wrap hook. No production fixture changed, and the test names no application or provider.
+3. **pnpm store-dir mismatch after the 0.2.1 bump.** The layer's `pnpm test` aborted without a TTY (`ERR_PNPM_ABORTED_REMOVE_MODULES_DIR_NO_TTY`). `pnpm install --frozen-lockfile --offline --store-dir /media/nvme/dev/golem15/summercms.io/summercms/.pnpm-store` fixed it with the lockfile sha256 unchanged and no package added. It is recorded in `deferred-items.md`.
+4. **Pre-existing gofmt drift in `modules/cabana` token files.** These are committed files from another session and are not touched here. They are logged in `deferred-items.md`; vet and the tests pass.
+5. **Framework tag `v0.2.1` instead of `v0.1.27`**, per the human's reply (see Task 5).
+6. **Most coverage tasks had no failing test first.** They test behaviour plans 07 and 08 already shipped, and no production bug surfaced, so no `fix(18.1-09)` commit exists. The plan is `type: execute`, so the plan-level TDD gate does not apply.
+
+**Total deviations:** 1 auto-fixed (Rule 3) and 6 adaptations.
+**Impact on plan:** test-side plumbing and one gate script allow-list. No scope or dependency was added.
+
+## Deferred items
+
+| Item | Status |
+|------|--------|
+| Layer `scripts/check-git-install.sh` targets `vue-journal-layer` | open (blocks an install check of layer v0.2.1) |
+| Review findings outside the gap closure (WR-05, IN-01 to IN-08) | open |
+| gofmt drift in `modules/cabana` token files | open (another session's files) |
+| pnpm store-dir mismatch in the layer | resolved for the gate; seen again and fixed locally |
+
+## Known Stubs
+
+None. This plan adds tests, gate entries and a version string only.
+
+## Self-Check: PASSED

 - **D-19 (S-5):** The hard-coded `metadata.app = 'queststream'` becomes a config key on the Stripe subscriptions plugin, empty by default (write nothing, filter nothing). Horoskopia's cutover sets it to `queststream`. `billing_owner_id` is dropped from the generic gateway; apps add metadata through a checkout options map.
 - **D-20 (S-8, S-9):** The Stripe subscriptions subpackage is its own party plugin, `golem15.pgstripesubscriptions`, at module path `git.golem15.com/golem15/sm-pgstripe-plugin/subscriptions`. It gets its own importable or package-local Stripe fake; P18's root `stripefake_test.go` stays unchanged.
 - **D-21:** Behaviour defaults: keep PHP's `cancel_at_period_end` mapping (a manual test-mode check decides whether `cancel_at` from the billing portal also needs handling); out-of-order events behave as PHP does; the job reads both pre-basil and basil payload shapes; customer `GET /subscription` returns the latest subscription with `has_access` and `in_grace_period` flags.
+- **D-21 amendment (2026-10-14, gap closure 18.1-07, user decision on verification human item 1):** out-of-order events no longer behave as PHP; created and updated events apply the subscription Stripe holds, serialised per subscription, and a deletion before its subscription is stored is retried. D-21's other defaults are unchanged.
+- **D-21 amendment (2026-10-16, quick 261016-nqk, UAT test 7 / gap G-18.1-7):** the test-mode check settled the `cancel_at` question. On API `2026-09-30.endive` a billing-portal cancel reports `cancel_at` (the period end) with `cancel_at_period_end` false; an API cancel reports both. pgstripe now stores `cancel_at_period_end` true when Stripe reports that flag or a `cancel_at` date on an active or trialing subscription; clearing `cancel_at` maps back to false and fires `reactivated`. The row keeps PHP's single flag; `cancel_at` itself is not stored.
 - **D-22 (plan split, 6 plans):** (1) framework: cabana flat reorder + `taglist`; (2) pgsub core tracer in the new repo (created with `tea repos create --owner golem15`); (3) pgstripe secret columns + import mapping + `subscriptions` plugin (gateway, both webhook routes, River job, host test); (4) pgsub admin screens + customer API; (5) `vue-paymentgateway-layer` pieces (tag `v0.2.0` only on go-ahead); (6) unit tests across all repos + `scripts/check-phase18.1.sh`. Plan 2's repo is committed before plan 3's `go.mod` points at it. No push, tag or deploy without the user's go-ahead.

+# Phase 18.1: Code Review Report (re-review after gap closure)
+
+**Reviewed:** 2026-10-16T12:04:37Z
+**Depth:** standard
+**Files Reviewed:** 44 (four repositories; every path carries its repository prefix)
+**Status:** issues_found
+
+## Summary
+
+This is the re-review after the gap closure. Plans 18.1-07, 18.1-08 and 18.1-09 targeted CR-01, CR-02, WR-01, WR-02, WR-03, WR-04, WR-06 and WR-07 of the first review (2026-10-14). Scope:
+- summercms.go: commits after `929cfd8`;
+- pgsub: commits after `472b75b`;
+- pgstripe: commits after `baf3c55`;
+- the layer: commits after `30046f5`.
+
+Called code outside the list was read where a finding depends on it: `lagoon.Transaction`, cabana's toolbar action path, `sync_plan.go`, conga's default attempts, and the pre-fix `subscriptionplans.go` and `SyncPlan`.
+
+Both blockers are closed. The webhook job now retrieves the subscription's state from Stripe outside any transaction. It does this under a per-subscription session advisory lock, and the claim-first marker transaction is unchanged. Checkout no longer falls back to another currency's price.
+
+The lock implementation holds up under tracing:
+- **Pinned connection.** GORM's `Connection` keeps the `*sql.Conn`. The `NewDB` session keeps the `ConnPool`, and `lagoon.Transaction` begins its transaction on that same connection.
+- **Unlock and discard.** The unlock runs with `context.WithoutCancel`. A failed lock or unlock marks the connection bad through `Conn.Raw` returning `driver.ErrBadConn`, so database/sql closes it and the server releases the lock.
+- **Framework change.** The cabana `Detached` branch keeps the list scope, the empty and partial-selection rules and the permission check. The new field is `json:"-"` and opt-in, so existing consumers (the `users` bulk actions in the apps) compile and behave as before.
+- **Layer.** The bfcache restore works in all three components, and the listener is removed on unmount.
+
+No new blocker was found. The seven warnings are:
+- **Residual gaps in fixed findings (WR-01, WR-04, WR-06).** `Service.Cancel` still writes a gateway-owned column without the subscription lock, so the spurious `reactivated` of CR-01 sequence 3 is still reachable through a race. The open-subscription guard cannot see unpaid Checkout Sessions. Checkout bills the last-synced amount, not the amount shown.
+- **New behaviour introduced by the fixes (WR-02, WR-03, WR-05, WR-07):**
+  - fresh-state retrieval can fire `SubscriptionCanceled` twice;
+  - the detached plan sync dropped the row lock that serialised concurrent syncs of one plan;
+  - the strict price map makes plans in gbp, cad, aud or chf impossible to buy once they are synced;
+  - treating `incomplete` as open locks a user out of checkout for up to about 23 hours.
+
+## Resolution of the first review's findings
+
+| Finding | Status | Evidence |
+|---|---|---|
+| CR-01 stale webhook snapshots | **Resolved** (one residual race, WR-01 below) | `sm-pgstripe-plugin/subscriptions/job.go:206-244` retrieves fresh state under `classes.WithSessionLock`. `apply.go:191-195` retries an unknown deletion. Sequences 1 to 3 are covered by `TestFreshStateSmoke` and `TestEventOrdering`. `Service.Cancel` does not take the lock (WR-01). |
+| CR-02 cross-currency checkout | **Resolved** for currency (amount residual, WR-06; side effect, WR-05) | `models/subscription_plan.go:129-144` `CheckoutPriceID` has no fallback. The API answers 422 at `api/subscription.go:128-131`, and the gateway refuses with `ErrNoPriceForCurrency` at `gateway.go:199-202`. The yen is dropped from `supportedCurrencies` (`gateway.go:44`). |
+| WR-01 Stripe calls inside the bulk transaction | **Resolved** (regression, WR-03) | `controllers/subscriptionplans.go:55` sets `Detached: true`. The branch is at `crud.go:370-373, 412-435`. `SyncPlan(ctx, nil, plan)` saves with `context.WithoutCancel` (`service.go:597-605`), and a failed save becomes a failure line. |
+| WR-02 duplicate Stripe customers | **Resolved** | `user_subscribable.go` writes the first value only and re-reads the stored one. `gateway.go:163-164` sets an idempotency key on the customer create. `ensureCustomer` stores through `WithoutCancel` (`service.go:631`). |
+| WR-03 already-subscribed guard | **Partially resolved** (WR-04 and WR-07 below) | `ScopeOpen` (`models/subscription.go:114-121`), `CheckoutGuarded` under `SubscriberLockKey` (`service.go:319-344`), and a checkout idempotency key (`gateway.go:245-246`). Unpaid open sessions are still not seen. |
+| WR-04 subscriptions on archived prices | **Resolved** | `apply.go:327-339` resolves the plan by price, then product, then plan code. `decode.go` carries `product_id`/`plan_code`. |
+| WR-05 grace period from the advanced period end | **Open (deferred)** | `models/subscription.go:149`, unchanged and kept PHP-identical by user decision (`deferred-items.md`). Not counted again below. |
+| WR-06 SyncSubscription lost update | **Resolved** | `service.go:418-488`: under the lock, `FOR UPDATE` re-read, `Select` of the gateway-owned columns, plan refreshed on the retriever path. |
+| WR-07 buttons stuck after Back | **Resolved** | `subscribe.ts:57-64, 66-71, 138, 195`. All three components wire `watchPageRestore` in `onMounted` and remove it in `onBeforeUnmount`. `MySubscription` also refreshes its data. |
+| IN-01 to IN-08 | **Open (deferred)** | `deferred-items.md`. Not counted again below. |
+
+## Narrative Findings (AI reviewer)
+
+## Warnings
+
+### WR-01: `Service.Cancel` writes `cancel_at_period_end` without the subscription lock, so a racing webhook job still fires a spurious `SubscriptionReactivated` (CR-01 sequence 3 residual)
+
+**Files:**
+- `sm-paymentgatewaysubscriptions-plugin/classes/service.go:373-395`
+- `sm-pgstripe-plugin/subscriptions/job.go:219-243`
+- `sm-paymentgatewaysubscriptions-plugin/classes/apply.go:143`
+- `sm-paymentgatewaysubscriptions-plugin/classes/lock.go:25-28`
+
+**Issue:** The lock's documented rule is "every writer of the gateway state of that subscription takes it", and plan 07 made that the established pattern. `Service.Cancel` (used by `POST /subscription/cancel`) calls Stripe and then runs `UPDATE ... SET cancel_at_period_end = true` without `SubscriptionLockKey`. One interleaving reproduces the original sequence 3:
+1. A webhook job for an unrelated `customer.subscription.updated` takes the lock and retrieves the subscription from Stripe (`cancel_at_period_end: false`).
+2. The user cancels. Stripe sets the flag, and the local UPDATE commits `true`.
+3. The job opens its transaction. `Apply` reads the row `FOR UPDATE` with `previousCancel = true`, writes `false` and fires `SubscriptionReactivated` (`apply.go:143`).
+
+Stripe's own update event later restores `true`, but the listeners have already received a reactivation the user never asked for. Until then the row shows no scheduled cancellation. The window is the time between the job's Stripe response and its `SELECT ... FOR UPDATE`. It is short, but nothing closes it.
+
+**Fix:** Take the subscription lock around the gateway call and the local write:
+```go
+func (s *Service) Cancel(ctx context.Context, sub *models.Subscription, atPeriodEnd bool) error {
+	...
+	if sub.StripeSubscriptionID == nil || *sub.StripeSubscriptionID == "" { /* existing gateway refusal */ }
+	return WithSessionLock(ctx, s.db, SubscriptionLockKey(*sub.StripeSubscriptionID), func(conn *gorm.DB) error {
+		if err := gw.CancelSubscription(ctx, sub, atPeriodEnd); err != nil { ... }
+		if !atPeriodEnd { return nil }
+		return conn.WithContext(ctx).Model(&models.Subscription{}).Where("id = ?", sub.ID).
+			Update("cancel_at_period_end", true).Error
+	})
+}
+```
+Add a `TestEventOrdering` case that blocks the fake's retrieve, runs `Cancel` and then releases the retrieve.
+
+### WR-02: With fresh-state retrieval, `SubscriptionCanceled` fires twice when a created/updated job runs after Stripe canceled the subscription but before its deletion job
+
+**Files:**
+- `sm-pgstripe-plugin/subscriptions/job.go:221-241`
+- `sm-paymentgatewaysubscriptions-plugin/classes/apply.go:161-165, 208-211`
+- `sm-pgstripe-plugin/subscriptions/ordering_test.go:115-152`, `fresh_state_smoke_test.go:130-170`
+
+**Issue:** A created or updated job now applies Stripe's current status. If Stripe already canceled the subscription, that status is `canceled`. `fireStateChangeEvents` sees a change to canceled and fires `SubscriptionCanceled`. The deletion job then runs `ApplyDeleted`, which fires `SubscriptionCanceled` unconditionally (`apply.go:208-211`, the PHP rule). Two sequences lead there:
+- **CR-01 sequence 2, the case plan 07 targeted:** the deletion is retried with `ErrSubscriptionNotStored`, the late created event stores `canceled` and fires once, and the retried deletion fires again.
+- **An immediate cancel while an update job is queued, retrying, or simply wins the lock first.**
+
+Under PHP's snapshot semantics a created or updated snapshot practically never carried `canceled`, so the unconditional fire was harmless. The fresh path changes that. Both ordering tests assert `activated == 0` but never count `canceled`, so the double fire passes the gate. Listeners such as a "your subscription ended" mail or an access revocation that writes an audit row run twice.
+
+**Fix:** In `ApplyDeleted`, fire only on a transition (`previous := sub.StripeStatus` before the write; fire when `previous != models.StatusCanceled`). Record it as a deviation next to the D-21 amendment. Then add `rec.Count(events.SubscriptionCanceledEventName) == 1` to both `deleted_before_created` subtests.
+
+### WR-03: The detached plan sync lost the row lock that serialised concurrent syncs of one plan; parallel syncs create duplicate Stripe products and prices
+
+**Files:**

+- `sm-pgstripe-plugin/subscriptions/sync_plan.go:92-117` (called)
+
+**Issue:** Before plan 08, `sync_to_stripe` ran inside cabana's transaction with the selected plans locked `FOR UPDATE`, so two admins, or two tabs, syncing the same plan were serialised. The detached branch loads the plans without locks (`loadScoped(..., false)`), and `SyncPlan` takes no lock of its own. Two concurrent syncs of a plan with no `stripe_product_id` each call `V1Products.Create`, which carries no idempotency key. Each then lists the prices by lookup key, finds none, and creates its own. The last `Updates` wins, and the other product and its prices stay active and orphaned in Stripe. This is the duplicate-product outcome WR-01 set out to prevent.
+
+The toolbar `sync_all_to_stripe` never locked. It has no confirm dialog (`subscriptionplans.go:59-63`), so a double click starts two full syncs.
+
+**Fix:** Serialise per plan with the existing helper, and sync from a fresh copy of the row:
+```go
+func (s *Service) SyncPlan(ctx context.Context, tx *gorm.DB, plan *models.SubscriptionPlan) (map[string]string, error) {
+	...
+	if tx == nil {
+		var out map[string]string
+		err := WithSessionLock(ctx, s.db, lockKeyPrefix+"plan:"+strconv.FormatUint(uint64(plan.ID), 10), func(conn *gorm.DB) error {
+			if err := conn.WithContext(ctx).First(plan, plan.ID).Error; err != nil { return err } // fresh stripe ids
+			var err error
+			out, err = s.syncPlanLocked(ctx, conn, plan)
+			return err
+		})
+		return out, err
+	}
+	...
+}
+```
+Also give `V1Products.Create` an idempotency key over the plan id, code and name, in the same window as the customer key.
+
+### WR-04: The open-subscription guard cannot see unpaid Checkout Sessions, so a subscriber can still complete two Checkouts and be billed twice (WR-03 partially resolved)
+
+**Files:**
+- `sm-paymentgatewaysubscriptions-plugin/classes/service.go:319-344`
+- `sm-pgstripe-plugin/subscriptions/gateway.go:245-246`
+- `sm-paymentgatewaysubscriptions-plugin/checkout_guard_test.go` ("two checkouts of one subscriber never overlap and share one customer")
+
+**Issue:** `CheckoutGuarded` refuses only when a stored row is open. A Checkout Session creates no row until the customer pays and the webhook is applied. The subscriber lock serialises the two requests but does not make the second one fail: the test named above asserts that both checkouts succeed. The Stripe idempotency key returns the same session only when every parameter matches within the same 10-minute window. So these still produce two open sessions for one customer:
+- two tabs with different plans or currencies;
+- the same plan more than 10 minutes apart (sessions stay valid for 24 h);
+- a second click in the gap between payment and webhook processing.
+
+Completing both produces two live Stripe subscriptions, both billing. That is the outcome WR-03 described.
+
+**Fix:** Before creating a new session for a customer, expire that customer's open subscription-mode sessions inside the subscriber lock (Stripe: list Checkout Sessions with `customer` and `status=open`, then `Expire`). Optionally, when `Apply` stores a new subscription for a subscriber who already has another open row, log at Error or fire a dedicated event so the duplicate is caught.
+
+### WR-05: Once synced, plans priced in gbp, cad, aud or chf can no longer be bought, although `/plans` lists them and `SupportsCurrency` accepts them
+
+**Files:**
+- `sm-paymentgatewaysubscriptions-plugin/models/subscription_plan.go:129-144`
+- `sm-pgstripe-plugin/subscriptions/sync_plan.go:15, 55-69` (called)
+- `sm-pgstripe-plugin/subscriptions/gateway.go:44`
+- `sm-paymentgatewaysubscriptions-plugin/api/subscription.go:121-131`
+
+**Issue:** `CheckoutPriceID` lets a non-empty `stripe_prices` map decide alone. Plan sync fills that map only for usd, eur and pln, and it overwrites `stripe_price_id` with the USD price. A plan with `currency: GBP` therefore:
+1. sells correctly while it carries a hand-entered GBP `stripe_price_id`;
+2. after an admin presses "Sync to Stripe" (reported as successful), loses its GBP price id and gets a map without `gbp`;
+3. answers 422 "unavailable" to every checkout from then on, while `/plans` still shows `29.99 GBP` with a Subscribe button.
+
+The same happens to any `currency_prices` key outside the three sync currencies. This is no longer a wrong charge, but the strict map combined with the unchanged fixed sync list makes a supported currency unsellable without any visible error.
+
+**Fix:** Sync every currency the plan prices that the gateway supports, instead of the fixed list:
+```go
+currencies := []string{strings.ToLower(plan.Currency)}
+for code := range plan.CurrencyPrices.Data { currencies = append(currencies, strings.ToLower(code)) }
+// dedupe, keep only g.SupportsCurrency(code), then upsertPrice for each
+```
+At least report the currencies the plan lists but has no price for as a sync failure line. Alternatively, have `/plans` mark a price unbuyable when `CheckoutPriceID` is empty.
+
+### WR-06: Checkout bills the amount of the last sync, not the price the API shows; an edit of `price_cents` or `currency_prices` without a re-sync charges the old amount (CR-02 amount residual)
+
+**Files:**
+- `sm-paymentgatewaysubscriptions-plugin/models/subscription_plan.go:129-144`
+- `sm-paymentgatewaysubscriptions-plugin/api/json.go:113-126`
+- `sm-paymentgatewaysubscriptions-plugin/api/subscription.go:121-131`
+
+**Issue:** `/plans` renders `currency_prices`/`price_cents` from the row (`planPrices`). The checkout gate (`priced`) checks the same local amounts. The Stripe price comes from the `stripe_prices` id, whose `unit_amount` was fixed at the last sync. Nothing ties the two together: there is no save hook on the plan form, and `CheckoutPriceID` never compares amounts. An admin who raises a plan from 29.99 to 39.99 and forgets to press Sync leaves customers who are shown 39.99 being billed 29.99, and the reverse after a price cut. CR-02 was "charge a different currency or amount than the user was shown". The currency half is fixed; the amount half is not.
+
+**Fix:** One of:
+1. Store the synced amount per currency next to the id (for example `stripe_prices` values as `{id, amount}`, or a parallel `stripe_price_amounts` map). Have `CheckoutPriceID` return "" when `PriceCentsFor(currency)` differs, which gives a 422 and an admin log line naming the plan.
+2. In the gateway, `V1Prices.Retrieve(priceID)` before the session and refuse with `ErrNoPriceForCurrency` when `UnitAmount != plan.PriceCentsFor(currency)`, `Currency` differs or `Active` is false.
+3. Clear `stripe_prices`/`stripe_price_id` in a `FormBeforeUpdate` when a price field changes.
+
+### WR-07: Treating `incomplete` as open locks a user out of checkout for up to about 23 hours after an abandoned or failed first payment
+
+**Files:**
+- `sm-paymentgatewaysubscriptions-plugin/models/subscription.go:114-121`
+- `sm-paymentgatewaysubscriptions-plugin/api/subscription.go:92-98`
+- `sm-paymentgatewaysubscriptions-plugin/classes/service.go:325-332`
+
+**Issue:** `ScopeOpen` excludes only `canceled` and `incomplete_expired`. A subscription whose first invoice failed, or which needs 3-D Secure the customer abandoned, is stored as `incomplete` from the `customer.subscription.created` event. Stripe expires it after about 23 h. Until then every checkout answers 409, and the layer offers only the billing portal (`SubscribeButton.vue:56`). The portal is not a reliable way to finish the first payment of an incomplete subscription, so a customer with a declined card cannot retry with another card the same day. The other statuses that block (`past_due`, `unpaid`, `paused`) have an invoice the portal can settle; `incomplete` is the exception.
+
+**Fix:** Leave `incomplete` out of the checkout guard. Stripe expires it, and an incomplete subscription never charges again on its own. If double billing through a later-completed incomplete subscription is a concern, have the guarded checkout cancel the subscriber's `incomplete` subscriptions at Stripe, inside the lock, before it creates the new session.
+
+## Info
+
+### IN-01: The `ErrSubscriptionNotStored` retry lasts only conga's 3 attempts; a deletion of a subscription that is never stored ends as a discarded job with error logs
+
+**Files:**
+- `sm-paymentgatewaysubscriptions-plugin/classes/apply.go:191-195`
+- `summercms.go/modules/conga/client.go:18-19` (called)
+
+**Issue:** River retries the deletion 3 times with backoff, roughly 20 s in total. CR-01 sequence 2 is actually closed by the fresh retrieval of the late created event, not by this retry. A subscription that never gets a row (pre-cutover PHP subscriptions, or the untagged events of another application, IN-02 of the first review) now produces three Error lines and a discarded River job per deletion, where it used to leave a marker.
+
+**Fix:** On the last attempt (`river.JobFromContext(ctx).Attempt >= MaxAttempts`), claim the marker and log at Warn instead of failing. Alternatively, document that the discarded jobs are expected.
+
+### IN-02: The session lock holds a pooled connection while it waits, and its holder needs a second one; with a capped pool or a re-entrant listener this stalls until the job timeout
+
+**Files:**
+- `sm-paymentgatewaysubscriptions-plugin/classes/lock.go:63-88`
+- `sm-pgstripe-plugin/subscriptions/gateway.go:114-128`
+- `sm-paymentgatewaysubscriptions-plugin/classes/service.go:325-339`
+
+**Issue:** Each waiter keeps a pinned connection blocked in `pg_advisory_lock`. The holder needs another connection: `LoadSettings` in `client()`, and in `CheckoutGuarded` the `Open`, `Subscriber` and `ensureCustomer` calls on `s.db`.
+- **Capped pool.** With `MaxOpenConns` at or below the number of concurrent jobs for one subscription, the holder starves until River's job timeout. Each timeout uses one of only 3 attempts, so an event can be discarded.
+- **Re-entrant listener.** An event listener that calls `Service.SyncSubscription` for the same subscription waits on a lock its own job holds. That also lasts until the context deadline.
+
+lagoon sets no cap today, so the default deployment is unaffected (plan 07 noted this).
+
+**Fix:** Document the pool requirement (at least 2 x workers). Consider `SET lock_timeout` on the pinned connection before the lock call, or `pg_try_advisory_lock` with a River snooze. Note in the events doc that listeners must not call `SyncSubscription` or `Cancel` for the subscription they are handling.
+
+### IN-03: A plan changed between the handler's price check and the gateway call answers 502 instead of 422
+
+**File:** `sm-paymentgatewaysubscriptions-plugin/api/subscription.go:128-131, 141-148`
+
+**Issue:** `ErrNoPriceForCurrency` from the gateway (for example, the plan was re-synced without that currency in between) goes through `writeGatewayError` and becomes 502 "provider". It is logged without the error.
+
+**Fix:** Map `errors.Is(err, ErrNoPriceForCurrency)` to the same 422 `currency` validation answer. That needs a gateway-neutral sentinel in `contracts`, because pgsub must not import pgstripe.
+
+### IN-04: The component wiring spec asserts source text, not behaviour
+
+**File:** `vue-paymentgateway-layer/tests/subscriptionComponents.test.ts:423-440`
+
+**Issue:** The test "the three components wire watchPageRestore on mount and remove it on unmount" matches regexes against the `.vue` sources. A refactor that keeps the strings but breaks the wiring, for example by registering on a different target, still passes. A correct rewrite, such as a composable `usePageRestore(flow)`, fails.
+
+**Fix:** Mount each component with `@vue/test-utils` (or the Nuxt test utils) and dispatch a `pageshow` with `persisted: true` on `window`. Assert that the button is enabled again and that `removeEventListener` runs on unmount.
+
+### IN-05: `/plans` still shows yen amounts divided by 100
+
+**File:** `sm-paymentgatewaysubscriptions-plugin/api/json.go:122, 126`
+
+**Issue:** Dropping `jpy` from `supportedCurrencies` stops yen checkouts, but a plan whose `currency` is JPY, or whose `currency_prices` include `jpy`, is still listed through `money.FromMinor` as one hundredth of its price (¥5 for 500). This was the second half of CR-02's yen note.
+
+**Fix:** Leave out of `planPrices` any currency the stripe gateway does not support, or refuse `jpy` in the plan form's validation.

+expected: Either accept them as PHP parity (D-21 and the frozen getStripePriceId fallback), recorded as overrides or a backlog item, or open a decimal gap-closure phase or quick task: CR-01 by retrieving the subscription from Stripe in the job (or an event.created watermark) and retrying ApplyDeleted on an unknown row; CR-02 by refusing a currency without its own entry in stripe_prices in api/subscription.go and in CreateCheckoutSession
+result: pass
+note: CR-01 fixed in plan 18.1-07 (fresh-state retrieval, deletion retry), CR-02 in 18.1-08 (currency without own price refused); both covered by tests
+
+### 2. Live Stripe test-mode checkout end to end: test-mode keys and the subscription webhook secret in pgstripe settings, `stripe listen --forward-to <host>/webhook/stripe/subscriptions`, run checkout from the layer playground (PgPlans -> PgSubscribeButton) with the user subscriber
+expected: Stripe Checkout opens on the plan's price in the shown currency; after payment the webhook answers 200 'Webhook received', the job stores the subscription as active, golem15.pgsub.subscription.activated fires once, GET /subscription answers has_access true; observe whether customer.subscription.created arrives as incomplete followed by updated active (the CR-01 race window)
+result: pass
+reason: duplicate of test 6; the same check passed live as test 6
+
+### 3. Billing-portal cancellation (D-21 cancel_at question): open the portal through PgManageSubscriptionButton, cancel the subscription, inspect the delivered customer.subscription.updated
+expected: If Stripe sends cancel_at_period_end: true, the row gets cancel_at_period_end true and PgMySubscription shows the will-cancel notice. If it sends only cancel_at (newer API versions), the row keeps cancel_at_period_end false and the cancellation is invisible; that would need a follow-up mapping
+result: pass
+reason: duplicate of test 7; the same check passed live as test 7
+
+### 4. Browser pass through the admin screens and the layer components
+expected: Taglist chips (Enter, comma, remove, suggestions, read-only) on the plan form; flat drag reorder of plans writes sort_order; bulk sync_to_stripe and toolbar sync_all_to_stripe toasts with per-plan failures; Subscriptions list filters and the preview subscriber partial; the layer's plans table, subscribe redirect, my-subscription cancel through PgConfirm, portal redirect; press Back from Stripe Checkout and check whether the subscribe button is stuck on 'Subscribing...' (review WR-07, unfixed in app/utils/subscribe.ts)
+result: pass
+retest: "retested 2026-10-16 after quick 261016-nqk: subscriber e-mail column, title "Subscription #1 (Pro)", Gateway/Status shown; all pass"
+first_result: issue
+reported: "Taglist pass; reorder pass; sync actions pass; playground subscribe, Back from Checkout and 409 pass. Subscriptions list: shows subscriber ID, expected some sort of field: type: relation select: email so we could easily identify subscriber. Otherwise works. Cancel through PgConfirm not run (blocked by test 7)."
+severity: minor
+note: "Part E re-run 2026-10-16 after un-cancel in the portal: E: Pass, everything works. Shows it will end 16.11 and Stripe portal says it will cancel at 16.11. Stripe reports cancel_at_period_end=true plus cancel_at for the API cancel; only the portal cancel sends cancel_at alone (G-18.1-7)."
+
+### 5. Disposition of the re-review warnings (18.1-REVIEW.md, 2026-10-16; 18.1-REVIEW-DISPOSITION.md lists all open) before the Horoskopia cutover
+expected: Each of WR-01 to WR-07 is accepted (backlog item or deferred-items entry) or scheduled as a quick task or decimal phase. The money- and listener-relevant ones: WR-02 SubscriptionCanceled fires twice in the deleted-before-created sequence (ordering_test.go never counts canceled); WR-01 Service.Cancel race; WR-03 concurrent plan syncs can create duplicate Stripe products (row lock lost with Detached); WR-04 unpaid open Checkout Sessions not refused; WR-06 checkout bills the last-synced amount, not the shown one; WR-05 gbp/cad/aud/chf plans become unbuyable after a sync; WR-07 incomplete blocks checkout for about 23 h
+result: pass
+note: all seven fixed in quick task 261016-myi (pgsub 2c9e5ef, pgstripe 2e44508); WR-02 now fires canceled once (deviation from PHP)
+
+### 6. Live Stripe test-mode checkout end to end: test-mode keys and the subscription webhook secret in pgstripe settings, `stripe listen --forward-to <host>/webhook/stripe/subscriptions`, checkout from the layer playground (PgPlans -> PgSubscribeButton) with the user subscriber
+expected: Checkout opens on the plan's price in the shown currency; after payment the webhook answers 200 'Webhook received'; the job logs source=stripe (fresh retrieval, not snapshot), stores the subscription active; golem15.pgsub.subscription.activated fires once even when created(incomplete) and updated(active) arrive together; GET /subscription answers has_access true. A second Subscribe answers 409
+result: pass
+note: source=stripe logged, activated fired once, second subscribe refused
+
+### 7. Billing-portal cancellation (D-21 cancel_at question): open the portal through PgManageSubscriptionButton, cancel the subscription, inspect the delivered customer.subscription.updated and the retrieved subscription
+expected: If Stripe reports cancel_at_period_end true, the row gets it and PgMySubscription shows the will-cancel notice. If it reports only cancel_at, the row keeps cancel_at_period_end false and the cancellation is invisible; that needs a follow-up mapping
+result: pass
+retest: "retested 2026-10-16 after quick 261016-nqk: portal un-cancel then cancel shows will end 16.11; pass"
+first_result: issue
+reported: "Fail. Subscription canceled on Stripe, playground still showing 'Days until renewal 30'"
+severity: major
+
+### 8. pgsub boots in an application built with `summer build`
+expected: A summer-built app with pgsub and pgstripe runs migrate, serve and admin:create
+result: pass
+retest: "demo app rebuilt without the boot overlay after quick 261016-myi boots, migrates and serves; UAT 4, 6, 7 ran on it"
+first_result: issue
+reported: "Found while setting up the UAT demo app: every command fails with 'party: boot golem15.paymentgatewaysubscriptions: ... boot service: database is not published' (boot.go bootService looks up *gorm.DB during Boot; generated main.go activates plugins before the database is published)"

+
+# Phase 18.1: Payment Gateway Subscriptions Verification Report
+
+**Phase goal:** The generic core of `Golem15.PaymentGatewaySubscriptions` and pgstripe's subscription gateway and webhook run on SummerCMS. Horoskopia's subscription flow (plans, checkout, Stripe webhook, `golem15.pgsub.*` events, cancel and portal) works as it does on PHP. Exceptions are the user's recorded amendments: event ordering (D-21 amendment, 2026-10-14), the portal `cancel_at` mapping (D-21 amendment, 2026-10-16), and the re-review fixes the user accepted in UAT row 5 (`canceled` fires once on a deletion, `incomplete` no longer blocks checkout).
+**Mode:** mvp. The ROADMAP goal is not in user-story form, so this report checks the goal text and its five success criteria, as the earlier verifications did.
+**Verified:** 2026-10-16T15:45:06Z
+**Status:** human_needed (one item: the release go-ahead)
+**Re-verification:** Yes. The previous report (2026-10-16T14:45Z) had no `gaps:`. It went stale (covered_changed) after two quick tasks: 261016-myi (WR-01 to WR-07 and G-18.1-8) and 261016-nqk (G-18.1-7 and G-18.1-4). This run verifies both in full and regression-checks plans 01 to 09 through the full gate.
+
+## Goal Achievement
+
+### Observable Truths (roadmap success criteria)
+
+| # | Truth | Status | Evidence |
+|---|-------|--------|----------|
+| 1 | SC-1: Subscription and SubscriptionPlan on a squashed, idempotent v2.4.0 baseline; subscribers registered at build time; built-in `user` subscribable | VERIFIED | TestBaselineSchema and TestUserSubscribable passed in this run's postgres stage. G-18.1-8: `boot.go` `bootService` now builds and publishes `*classes.Service` through `lagoon.OnDatabase`, so plugins can activate before a command opens the database (generated main.go order). TestBootBeforeDatabase passed here. UAT row 8 passed on a demo app built with `summer build`. The user resolver gained an optional `ResolveMany` (`contracts.SubscriberBatchResolver`). It still writes only `stripe_customer_id`. |
+| 2 | SC-2: Stripe implementation of the gateway incl. `syncPlanToGateway`; both webhook routes verify, enqueue, process idempotently, fire the six events | VERIFIED | `subscriptions/job.go` `applySubscription` is unchanged: marker check, then foreign-app claim, then `WithSessionLock(SubscriptionLockKey)`, then retrieve outside a transaction, then claim and Apply in one transaction. G-18.1-7: every mapping path goes through `subscriptionObject.args()`: the snapshot (`decode.go:222-226`), the fresh retrieve (`gateway.go:468-475`) and `Gateway.SyncSubscription` (`gateway.go:415-422`). `pendingCancel()` (`decode.go:162-167`) maps Stripe's flag, or `cancel_at` on an active or trialing subscription, to `cancel_at_period_end`. WR-02: `ApplyDeleted` fires `canceled` only when the row was not already canceled (`apply.go:241-243`). Passed here: TestFreshStateSmoke incl. `portal_cancel_at_only_then_uncancel` (reactivated exactly once) and `deleted_before_created` (canceled == 1); TestEventOrdering incl. `deleted_before_created` (canceled == 1, `ordering_test.go:152`); TestDecodeSubscription/a_cancel_at_date…; TestHostSubscriptionFlow; TestSubscriptionWebhookSmoke; TestSubscriptionJob. UAT rows 6 and 7 passed against real Stripe test mode. |
+| 3 | SC-3: admin screens, Go service API, headless customer API, layer components | VERIFIED | Admin: `models/subscription/columns.yaml` gains a `subscriber` column, filled per page by `subscriptionsAdminController.ListExtendRecords`. Type and id stay as invisible searchable columns. The preview title comes from `FormRecordTitle`, and the label element reads its `value` property (`assets/js/fields.js`). Framework: `pact.ListExtendRecords` and `pact.FormRecordTitle` (`capabilities.go:737-763`); the SPA uses `meta.title`; dist rebuilt and matching. Service API: `Cancel` takes `SubscriptionLockKey` (`service.go:471-499`). `CheckoutGuarded` refuses on `CheckoutBlocker`, cancels incomplete subscriptions and expires open sessions inside `SubscriberLockKey` (`service.go:351-437`). `SyncPlan` with a nil tx runs under `PlanLockKey` on a re-read plan (`service.go:693-712`). Customer API: 409 on `CheckoutBlocker`; 422 on `CheckoutPriceID == ""` and on `contracts.ErrPriceUnavailable` (`api/subscription.go:93-171`). Layer: unchanged at v0.2.1; 112/112 TAP. UAT row 4 passed in a browser, covering admin and layer, including Back from Checkout and the subscriber e-mail and title. |
+| 4 | SC-4: host test proves checkout, activation, invoice.paid, past_due grace, cancel, duplicate idempotency against a Stripe fake | VERIFIED | TestHostSubscriptionFlow passed in this run (postgres stage, pgstripe `./subscriptions`, 12 required tests). |
+| 5 | SC-5: unit tests delivered in the phase's last plan | VERIFIED | Plan 09 is the last plan, and the gate requires its names by stage and package. The quick tasks are outside the phase's plan sequence. Each carries named tests in its fix commits: pgsub TestCheckoutIncompleteAndOpenSessions, TestCancelTakesSubscriptionLock, TestSyncPlanSerialised, TestCheckoutPriceUnavailable, TestBootBeforeDatabase, TestLabelElementValueProperty; pgstripe TestReviewFixesGateway (4 subtests) and the cancel_at subtests; cabana TestListUnstoredColumn, TestListExtendRecords, TestFormRecordTitle. All passed when run by name here, with 0 skips. The gate does not pin these names (see Anti-Patterns, INFO). |
+
+**Score:** 5/5 roadmap truths verified (0 present, behavior-unverified).
+
+### Plan must-haves: changes since the previous report
+
+The previous report verified plans 01 to 09 (65 truths). This run re-checked all of them through the full gate (below). The rows here are the truths whose status or wording changed.
+
+| Plan | Truth | Status | Evidence |
+|------|-------|--------|----------|
+| 07 | CR-01 seq 3: an older queued updated after Service.Cancel fires no reactivated | VERIFIED | Was `coincidental-reliance`. `Service.Cancel` now calls the gateway and writes the flag inside `WithSessionLock(SubscriptionLockKey)`, so a job that has already retrieved Stripe's state finishes before the cancel starts. TestCancelTakesSubscriptionLock passed: Cancel blocks while another session holds the lock and makes no gateway call until the lock is released. TestFreshStateSmoke/stale_update_after_cancel_no_reactivated and TestEventOrdering/stale_cancel_flag_no_reactivated also passed |
+| 08 | WR-07: bfcache restore re-enables the three components; listener removed on unmount | VERIFIED (human UAT, row 4) | Was PRESENT_BEHAVIOR_UNVERIFIED. UAT row 4: "playground subscribe, Back from Checkout and 409 pass". The layer's last commit (22368c5, 13:35+02:00) predates the UAT record (15:34Z) |
+| 02 | ApplyDeleted sets canceled and ended_at and fires canceled unconditionally | VERIFIED (amended) | Changed by the user-accepted fix of review WR-02 (UAT row 5 note: "WR-02 now fires canceled once (deviation from PHP)"). It now fires only on the transition into canceled (`apply.go:241`). On the paths PHP could reach, the listener count is still one. The pgsub README states the deviation (README:36) |
+| 03 | D-21: PHP's cancel_at_period_end mapping kept; prices for usd, eur and pln | VERIFIED (amended) | D-21 amendment of 2026-10-16 in 18.1-CONTEXT.md:69: `cancel_at` on active or trialing maps to the flag. COVERAGE.md row "subscription cancel_at" is INTEGRATE. Sync currencies are now usd, eur and pln plus every supported currency the plan prices (`sync_plan.go:24-41`, WR-05), a superset of the original. TestReviewFixesGateway/WR-05 passed |
+| 04 | Subscriptions list with subscriber type, subscriber id, plan, status, period end… | VERIFIED (amended) | G-18.1-4: type and id are still columns, now invisible but searchable, and the visible `subscriber` column shows the e-mail. UAT row 4 retest passed ("subscriber e-mail column, title 'Subscription #1 (Pro)', Gateway/Status shown") |
+| 08 | WR-03: 409 for any status but canceled/incomplete_expired (incl. incomplete); session idempotency key per subscriber/plan/currency | VERIFIED (amended) | Changed by the user-accepted fixes of review WR-07 and WR-04 (UAT row 5). `incomplete` no longer blocks checkout (`models/subscription.go:133-135`); the guarded checkout cancels it at the gateway first. The session idempotency key was replaced by expiring the customer's open subscription sessions inside the subscriber lock (`gateway.go` `ExpireOpenCheckoutSessions`), which is stronger: at most one payable session. TestCheckoutIncompleteAndOpenSessions, TestCheckoutGuarded and TestReviewFixesGateway/WR-04 passed |
+| 08 | WR-01 residual (lost per-plan serialisation, review WR-03) | VERIFIED | `SyncPlan` with a nil tx holds `PlanLockKey` and re-reads the plan; `V1Products.Create` carries an idempotency key. TestSyncPlanSerialised (one product from two concurrent syncs) and TestReviewFixesGateway/WR-03 passed |
+| 08 | CR-02 amount residual (review WR-06) | VERIFIED | `checkPrice` (`gateway.go`) retrieves the price before the session and refuses a missing, inactive, other-currency or other-amount price with `ErrNoPriceForCurrency`, which wraps `contracts.ErrPriceUnavailable` (`gateway.go:33`). The API answers that with 422. TestCheckoutPriceUnavailable and TestReviewFixesGateway/WR-06 passed |
+| 09 | D-22 release | VERIFIED (for plan 09's scope) | The tags plan 09 recorded are still on origin. The quick-task commits that followed are unreleased: see the human item and the Anti-Patterns WARNING |
+
+The amended rows follow the precedent set when D-21 was amended for ordering. A user decision recorded in UAT or CONTEXT changes the contract, and the code is checked against the amended contract. Two amendments are recorded only in UAT row 5 and the pgsub README, not in 18.1-CONTEXT.md § Amendments: WR-02 (canceled once) and WR-07 (incomplete no longer blocks). `apply.go:205` says the deviation is "recorded next to the D-21 amendment", but CONTEXT does not record it (INFO).
+
+**Plan must-have score:** 65/65 verified (4 as amended, 1 by human UAT). 0 present-behavior-unverified.

+
+### Anti-Patterns Found
+
+| File | Line | Pattern | Severity | Impact |
+|------|------|---------|----------|--------|
+| sm-paymentgatewaysubscriptions-plugin/go.mod | 7, 149 | requires `summercms v0.2.1`, but HEAD calls `pact.ListExtendRecords` and `pact.FormRecordTitle`, which are in no framework tag; it builds only through its own `replace ../summercms.go`, which a consuming module ignores | WARNING | pgsub HEAD cannot be consumed by tag or pseudo-version until the framework is tagged and the require bumped. This is the human release item |
+| sm-paymentgatewaysubscriptions-plugin, tag v0.1.0 | n/a | released plugin lacks G-18.1-8 | WARNING | an app built with `summer build` on pgsub v0.1.0 fails every command ("database is not published"). Fixed on main (ab46d6f), unreleased |
+| scripts/check-phase18.1.sh | required names | the quick-task tests (above) are not in the gate's required lists; 18.1-VALIDATION.md has no rows for them | INFO | the gate would not notice if they were skipped or removed. They passed here by name |
+| .planning/phases/18.1-…/18.1-CONTEXT.md | § Amendments | WR-02 (canceled once) and WR-07 (incomplete no longer blocks) deviations not recorded; `apply.go:205` claims they are "recorded next to the D-21 amendment" | INFO | decision trail sits in UAT row 5 and the README only |
+| docs/backend/forms.md | FormRecordTitle paragraph | the example title "Subscription #12 (Pro)" | INFO | generic concept, no application named; the framework rule holds |
+
+No TBD, FIXME, XXX, TODO or HACK markers in the files these quick tasks changed: pgsub classes, api, models, contracts, controllers, boot and assets; pgstripe subscriptions gateway, decode, sync_plan and job; cabana list_schema, query, crud and relation_field; pact capabilities; FormView and PreviewView.
+
+IN-01 to IN-05 of the re-review stay open as info. The disposition records them. IN-03 (502 instead of 422 on a gateway price refusal) is now closed in effect: the API maps `ErrPriceUnavailable` to 422.
+
+### Prohibitions (judgment tier, autonomous LLM verdict, non-authoritative)
+
+| Source | Prohibition | Verdict |
+|--------|-------------|---------|
+| 02, 04, 07 | pgsub imports no stripe-go (D-06) | holds (0 deps, run here) |
+| 01, 08 | Framework code and docs name no consuming application; generic additions only | holds. The bc5685e and 013890c diffs name no app or provider. One docs example uses "Subscription #12 (Pro)" as a sample title (INFO) |
+| 07 | No Stripe call while a DB transaction is open in the job or SyncSubscription | holds by reading. The new Cancel and CheckoutGuarded Stripe calls also run under session locks with no transaction open |
+| 02 | Built-in user subscribable writes no users column other than stripe_customer_id | holds. `ResolveMany` only reads (TestUserSubscribable) |
+| 03, 06, 09 | No test calls the network; test-only secrets | holds per the fake (BackendOverride); the new subtests use the same fake. Not audited line by line. Flagged |
+| 06, 09 | Gate never green on a skip or missing Docker | holds: PHASE181_REQUIRE_POSTGRES=1, 0 skip lines |
+| 09, quick tasks | Nothing pushed or tagged without the user's reply | holds: sibling repos are ahead of origin (pgsub 4, pgstripe 2), and no new tags exist. Hence the human release item |
+| 08 | Another session's uncommitted edits never staged | the working tree still holds other sessions' STATE.md and state.json edits, untouched. Flagged |
+
+### Decision Coverage
+
+All trackable CONTEXT.md decisions are honored by shipped artifacts (24/24).
+
+### Human Verification Required
+
+UAT evidence (Step 8b): `18.1-UAT.md` is `complete`, recorded at 2026-10-16T15:34:36Z. `verification.uat-evidence` reports `changed_since_uat: []` for the covered framework files. The sibling repos' last commits are also older than the record: pgsub 17:22+02, pgstripe 17:07+02, layer 13:35+02. Their working trees are clean. Rows 4, 5, 6, 7 and 8 passed on that code and settle every human item of the previous report (see `human_verified`). Rows 2 and 3 are skipped duplicates of 6 and 7. No row needs a retest.
+
+One new item remains:
+
+1. **Release go-ahead.** Tag the framework v0.2.2, bump and tag pgsub, then pgstripe, and push all three. Until then the tagged pgsub v0.1.0 does not boot in a `summer build` app, and pgsub main cannot be required by a consumer. This needs the user's go-ahead under the project rule. If the user defers it, record the reason (for example "released together with the Horoskopia port").
+
+### Gaps Summary

+No success criterion and no plan must-have failed. The two quick tasks did what they claim:
+- **WR-01:** Cancel is serialised with the webhook job.
+- **WR-02:** `canceled` fires once.
+- **WR-03:** plan syncs are serialised, and the product create is idempotent.
+- **WR-04:** open checkout sessions are expired.
+- **WR-05:** non-sync currencies stay sellable.
+- **WR-06:** a stale price is refused with 422.
+- **WR-07:** `incomplete` no longer locks a user out.
+- **G-18.1-7:** a portal `cancel_at` shows as will-cancel.
+- **G-18.1-4:** the admin shows the subscriber's e-mail and a record title.
+- **G-18.1-8:** pgsub boots in a summer-built app.
+
+Each fix has a named test that passed in this run, and the live UAT passed on the same code.
+
+The status is `human_needed` only because the fixes are not released. The tagged plugins still carry the boot blocker, and pgsub main depends on framework hooks that no tag has. Releasing needs the user's go-ahead.

 - The layer's `scripts/check-git-install.sh` targets `vue-journal-layer`

   **Plan 18.1-06:** left open. Neither the phase gate (`scripts/check-phase18.1.sh`) nor the plan's release task runs it, so the release does not depend on it. It is listed on the final push sheet: after a `v0.2.0` tag, an install check of the tag needs this script fixed first (a quick task against the layer).

   **What:** `../vue-paymentgateway-layer/scripts/check-git-install.sh`, shipped since v0.1.0 and run by `pnpm run check:git-install <tag>`, was copied from the journal layer. `REPO_URL`, the scratch app's dependency name, `extends` and the messages (12 "journal" references) point at `vue-journal-layer`, and it expects `testing/expect-acme.txt`, which the payment gateway layer does not have. Running `pnpm run check:git-install v0.2.0` would check the wrong repository.

   **Resolved by:** plan 18.1-06. `scripts/check-phase18.1.sh layers` (and `--all`) ran the layer suite green from a clean shell with the lockfile unchanged. The gate never installs: if pnpm aborts with `ERR_PNPM_ABORTED_REMOVE_MODULES_DIR_NO_TTY`, the layer stage fails and prints the offline, frozen-lockfile recovery command.

   **What:** the layer's `node_modules` was installed against the store `/media/nvme/dev/golem15/summercms.io/summercms/.pnpm-store/v11`, but pnpm 11.3.0 now resolves `/media/nvme/.pnpm-store/v11`. After any `package.json` change, `pnpm test` runs `pnpm install` first and aborts without a TTY (`ERR_PNPM_ABORTED_REMOVE_MODULES_DIR_NO_TTY`). Plan 05 fixed the local state with `pnpm install --frozen-lockfile --offline --store-dir /media/nvme/dev/golem15/summercms.io/summercms/.pnpm-store`, which left the lockfile unchanged and added no package.

+  **Recorded by:** plan 18.1-09 Task 4.

+  - IN-01: the per-user throttle key of the customer API never applies.
+  - IN-02: the `metadata_app` filter lets untagged events from other applications through.
+  - IN-03: the admin sync result shows the raw Stripe error text.
+  - IN-04: the plans table decides "free" differently from the server.
+  - IN-05: TaglistField leaves a typed separator in the input when the draft is empty.
+  - IN-06: the taglist required message is not localized; `customTags: false` without options is accepted at boot.
+  - IN-07: test-mode and live-mode Stripe customer ids share `users.stripe_customer_id`.
+  - IN-08: repository hygiene of the new plugin module (among others, sm-paymentgateway-plugin has no tag, so consumers keep its `replace`).
+  **Fix:** a later phase or quick tasks, one per finding.

+## Phase Goal
+
+ROADMAP Goal (not in user-story format; MVP mode would take a story from `/msd mvp-phase 19.3`, which was not run, so no story is invented here): the framework has the transport and infrastructure pieces a multi-client, multi-instance application needs: JWT cookie refresh across subdomains, credentialed CORS, a cache module with a Redis-backed rate-limit store, an S3 blob option, an OpenAPI page and Turnstile verification.
+
+This plan's slice (plan 1 of 5, wave 1): SC-2. The dependency decision note lands first, then the new `cooler` module: a Redis-backed `surf.Store` wired by `serve` so rate limits hold across instances (the tracer), then the Laravel-core cache API with memory (otter v2) and Redis drivers. Plans 02, 03 and 04 build on this checkout in wave 2.
+
+## Spec-less probe fallback
+
+No SPEC.md and no REQUIREMENTS IDs exist for this phase: the orchestrator recorded "spec-less probe fallback skipped: phase has no requirement IDs to probe (visible skip)". No probe predicates were generated. `must_haves` derive from the ROADMAP success criteria SC-1..SC-4 and the CONTEXT decisions D-01..D-19; prohibitions are recalled in-prompt and descriptor-less (flagged unverified).
+
+## Decisions taken in this plan (Claude's discretion)
+
+- Memory driver: otter v2 (bounded size, per-entry TTL, atomic Compute for Increment, injectable clock). A stdlib map was rejected because a key-per-client cache grows without bound. The decision note records it (D-07 discretion).
+- `serve` treats an unreachable Redis at start-up as a warning, not a boot failure, consistent with the user's answer that rate limits fall back to per-instance memory when Redis is down. A missing or malformed `redis.url` with a Redis driver selected stays a boot error (configuration, not availability).
+- Key prefix: `cache.prefix`, default derived from `app.name` (lower-cased, every run of characters outside `[a-z0-9]` replaced by `_`, then `:`), or `summer:` when `app.name` is empty. Cache keys are `<prefix>cache:<key>`, rate-limit keys `<prefix>rl:<key>`.
+- `Remember` degrades instead of failing a page: when the read fails it runs the callback and returns its value, skips a failing write, and logs a warning at most once per minute. The other methods return their errors.
+- `cooler.FromApp` gives commands other than `serve` (the dedicated job worker, console commands) the configured cache lazily; go-redis does not dial at construction.
+
+<assumption_delta_decision>
+add-alongside: the rate-limit store pluralizes from memory to memory|redis. surf.MemoryStore stays the default and the fallback; the Redis store is added next to it behind `http.rate_limit.store: redis`. No existing behaviour changes for apps that set nothing.
+</assumption_delta_decision>
+
+## Artifacts this phase produces (this plan)
+
+- Decision note `.planning/notes/2026-10-15-cooler-go-redis-otter.md`.
+- Module `modules/cooler`: `cooler.Cache` (methods `Get`, `Set`, `Has`, `Forget`, `Remember`, `Increment`, `Flush`), `cooler.Attempter`, `cooler.Handle` (methods `Close`, `Cache`, `RateLimitRedis`, `RateLimitStore`), `cooler.Install`, `cooler.FromApp`, `cooler.OpenRedis`, `cooler.NewMemoryCache`, `cooler.NewRedisCache`, `cooler.RateLimitStore` with `cooler.NewRateLimitStore` and method `Attempt`, constants `cooler.RedisURLKey` (`redis.url`), `cooler.CacheDriverKey` (`cache.driver`), `cooler.CachePrefixKey` (`cache.prefix`), `cooler.CacheMaxEntriesKey` (`cache.memory.max_entries`), `cooler.RateLimitStoreKey` (`http.rate_limit.store`), `cooler.DefaultMaxEntries` (10000), `cooler.PingTimeout` (3 s), `cooler.AttemptTimeout` (500 ms).
+- Config keys: `redis.url`, `cache.driver` (`memory`|`redis`), `cache.prefix`, `cache.memory.max_entries`, `http.rate_limit.store` (`memory`|`redis`).
+- `modules/surf`: unexported `installCooler(ctx, app) (*cooler.Handle, error)` in serve.go; `BuildRouter` looks up a published `surf.Store`.
+- Smoke tests: `TestBuildRouterStoreSmoke`, `TestRateLimitAcrossInstancesSmoke` (Docker) in `modules/surf/store_lookup_test.go`; `TestOpenRedisRedactsSmoke`, `TestMemoryCacheSmoke`, `TestRedisCacheSmoke` (Docker) in `modules/cooler/smoke_test.go`. Full unit coverage is plan 05.
+- Docs: new `docs/services/caching.md`; `docs/services/rate-limiting.md` section "Sharing limits across instances"; rows in `docs/setup/configuration.md`; the scaling note in `docs/architecture/performance-and-scaling.md`; cooler README; surf README configuration and dependency rows; root README table row.
+- Dependencies: `github.com/redis/go-redis/v9` v9.23.0, `github.com/maypok86/otter/v2` v2.3.0.
+
+<objective>
+Land the dependency decision note, then the `cooler` module: a Redis-backed rate-limit store that `serve` wires before the router (rate limits hold across instances), and the Laravel-core cache API with memory and Redis drivers, documented in the same commits.
+
+Purpose: SC-2 and D-06..D-09, D-19. Plans 02 and 04 extend surf and cooler on top of this; plan 03 needs the decision note for s3blob.
+Output: one docs commit (the note), then code commits with README and docs, all green under go vet and go test.

+Concurrency: Phase 18.1 gap-closure plans may run in parallel in this checkout (they touch modules/pact, modules/cabana and docs/backend, not this plan's files). Before Task 1 run `git status --porcelain -- go.mod go.sum modules/surf modules/cooler README.md docs/services docs/setup docs/architecture`; if it lists a file this plan touches, stop and report (never stash or overwrite another session's work). Stage files by explicit path; no co-author tags; the decision note (planning doc) and code go in separate commits; a module README and the docs pages change in the same commit as the code they describe. Docker-backed smoke tests skip under `-short`; run them on a Docker host (if the socket is denied although the user is in the docker group, run through `sudo -u golem`) and record NOT RUN in the SUMMARY when no daemon answers.

Write `.planning/notes/2026-10-15-cooler-go-redis-otter.md` in the structure of the hashids note (Decision, Related dependencies, Consequences): go-redis `github.com/redis/go-redis/v9` v9.23.0 is the Redis client (locked by D-07; official client; ParseURL handles redis, rediss and unix URLs; NewScript and Run give EVALSHA with EVAL fallback); otter `github.com/maypok86/otter/v2` v2.3.0 is the memory driver (bounded MaximumSize, per-entry ExpiryCalculator, atomic Compute, injectable Clock, no runtime dependencies; a stdlib map was rejected as unbounded); miniredis `github.com/alicebob/miniredis/v2` v2.40.0 is test-only, installed in plan 05 only after a blocking human check of the package; `gocloud.dev/blob/s3blob` comes from the already-required gocloud.dev v0.46.0, is imported only by a file under the `summercms_s3` build tag (plan 03) and adds AWS SDK v2 modules to go.mod and go.sum as indirect requirements; the Docker-backed Redis tests use the generic testcontainers Run with redis:7-alpine (no new module). Commit the note alone (`docs(19.3): decide cooler dependencies`) before the first go.mod change.
+
+Then `go get github.com/redis/go-redis/v9@v9.23.0`.
+
+cooler (package doc names the module role; errors prefixed `cooler:`; cooler imports neither surf nor cabana):
+- cooler.go: the key constants listed in this plan's Artifacts; `Attempter` with exactly surf.Store's Attempt signature; `Handle` with `Close() error`, `RateLimitRedis() bool` and `RateLimitStore(fallback Attempter) Attempter`; `Install(ctx context.Context, app *backpack.App) (*Handle, error)`: nil-app guard; `http.rate_limit.store` empty means memory, any value other than memory or redis is a boot error naming the key; when redis is selected, `redis.url` empty is a boot error naming the key (and the SUMMER_REDIS__URL variable), else `OpenRedis` builds the client and a Ping bounded by `PingTimeout` runs; a failed Ping logs one warning (the endpoint host only, never the URL) and boot continues. The prefix helper resolves `cache.prefix` as described in this plan's Decisions.
+- redis.go: `OpenRedis(ctx context.Context, rawURL string) (*redis.Client, error)` parses with redis.ParseURL and on error returns a fixed message naming `redis.url` and the accepted schemes without wrapping or quoting the raw error (Pitfall 7); sets DisableIdentity true and MaintNotificationsConfig mode disabled (Pitfall 14); does not dial.
+- ratelimit.go: `RateLimitStore` built by `NewRateLimitStore(client *redis.Client, prefix string, fallback Attempter) *RateLimitStore`; the Lua script of RESEARCH Pattern 2 as a package-level redis.NewScript; `Attempt` runs it with key `<prefix>rl:<key>`, ARGV max and decay in milliseconds clamped to at least 1, under a context bounded by `AttemptTimeout`; it maps the three integers to (allowed, attempts, retryAfter as milliseconds); on any Redis error it returns fallback.Attempt(key, max, decay) and logs one warning per minute at most.
+
+surf: serve.go gains `installCooler(ctx, app) (*cooler.Handle, error)` called after publishUploads and before BuildRouter (deferred Close); when `RateLimitRedis()` it publishes `app.Publish[Store](h.RateLimitStore(NewMemoryStore(2*time.Minute)))`. router.go BuildRouter: when app is non-nil and `app.Lookup[Store]()` returns a non-nil store, use it; otherwise NewMemoryStore(2*time.Minute) as today. routelist_command.go is not changed: route:list never installs cooler.
+
+Docs in the same commit as the code: cooler README in the standard structure (summary sentence "Cache drivers and shared counters for SummerCMS: memory and Redis caches with a key prefix and TTLs, and a Redis-backed rate-limit store.", mnemonic about a cool box at the beach keeping things fresh and at hand; at this commit list only identifiers that exist); root README table row (alphabetical, after conga) with that sentence and the mnemonic; surf README Configuration row `http.rate_limit.store` and the serve paragraph (serve installs cooler), Dependencies gains cooler; docs/services/rate-limiting.md: a section "Sharing limits across instances" (keys, the memory fallback with its warning, route:list never dials) and the sentence that each instance counts on its own now says it applies to the memory store; docs/setup/configuration.md rows `redis.url` and `http.rate_limit.store`; docs/architecture/performance-and-scaling.md: the rate-limit note points at the Redis store. No application or client is named.
+
+Smoke tests (plan 05 owns full coverage): modules/surf/store_lookup_test.go `TestBuildRouterStoreSmoke` (no Docker: an app with http.rate_limit.store redis and redis.url redis://127.0.0.1:1 but no install builds a router whose limiter store is a *MemoryStore and returns within a second; an app with a published counting fake Store routes a throttle:2,1 request through the fake) and `TestRateLimitAcrossInstancesSmoke` (skips under -short; redis:7-alpine through testcontainers.Run; two apps share redis.url, each runs installCooler and surf.Assemble with a test plugin route GET /ping carrying throttle:2,1; requests A, B, A answer 200, 200, 429 with Retry-After); modules/cooler/smoke_test.go `TestOpenRedisRedactsSmoke` (a URL carrying user, password and a control character yields an error whose text contains neither the user nor the password; a rediss URL parses).</action>

+cooler.go: the `Cache` interface with `Get(ctx, key) ([]byte, bool, error)`, `Set(ctx, key string, value []byte, ttl time.Duration) error` (ttl 0 or less is forever), `Has(ctx, key) (bool, error)`, `Forget(ctx, key) error`, `Remember(ctx, key string, ttl time.Duration, fn func(context.Context) ([]byte, error)) ([]byte, error)` (degrades as this plan's Decisions say), `Increment(ctx, key string, by int64) (int64, error)` (a missing key starts at 0 and gets no TTL; an existing key keeps its expiry, as Redis INCRBY does), `Flush(ctx) error`. Install reads `cache.driver` (empty means memory; anything but memory or redis is a boot error naming the key), builds the driver, reuses a Cache that FromApp already published, otherwise publishes `app.Publish[Cache]`; `Handle.Cache()` returns it. When both the cache and the rate limiter use Redis they share one client. `FromApp(app *backpack.App) (Cache, error)` returns the published Cache or builds the configured one without a Ping and publishes it (on a duplicate-publish race it returns the winner).
+
+memory.go: `NewMemoryCache(prefix string, maxEntries int) (Cache, error)` on otter v2 with MaximumSize from `cache.memory.max_entries` (default DefaultMaxEntries; zero or negative is a boot error naming the key) and an ExpiryCalculator reading an absolute expiresAt stored with the value (forever as an excessively long period, per otter's docs); Increment uses Compute so it is atomic per key; values are copied on Set and Get so callers cannot mutate stored bytes.
+
+rediscache.go: `NewRedisCache(client *redis.Client, prefix string) Cache`; keys `<prefix>cache:<key>`; Set uses SET with PX (no expiry when ttl is 0 or less); Has uses EXISTS; Forget uses UNLINK; Increment uses INCRBY; Flush walks SCAN MATCH `<prefix>cache:*` in batches of 500 and removes each batch with UNLINK (never the database-wide flush command, which would also drop rate-limit counters and other apps' keys).

+## Trust Boundaries
+
+| Boundary | Description |
+|----------|-------------|
+| application to Redis | network hop carrying credentials in redis.url and shared counters other instances trust |
+| request data to cache and limiter keys | keys can derive from client IPs, user ids or request values |
+| config and environment to boot | redis.url and driver keys come from YAML or SUMMER_ variables |
+
+## STRIDE Threat Register
+
+| Threat ID | Category | Component | Severity | Disposition | Mitigation Plan |
+|-----------|----------|-----------|----------|-------------|-----------------|
+| T-19.3-01 | Information disclosure | cooler.OpenRedis, Install errors and logs | high | mitigate | parse errors are replaced by a fixed message naming the key, never the URL or the raw url.Parse text; the Ping warning logs only the host; TestOpenRedisRedactsSmoke asserts user and password are absent |
+| T-19.3-02 | Denial of service | RateLimitStore.Attempt during a Redis outage | medium | mitigate | per-instance MemoryStore fallback (no site-wide 429, no unlimited traffic), warning at most once per minute, 500 ms bound per attempt |
+| T-19.3-03 | Tampering | cache and limiter key space on a shared Redis | medium | mitigate | `<prefix>cache:` and `<prefix>rl:` namespaces; Flush is SCAN plus UNLINK under the cache namespace only; go-redis sends keys as arguments (no command injection) |
+| T-19.3-04 | Denial of service | memory cache growth from request-derived keys | medium | mitigate | otter MaximumSize from cache.memory.max_entries (default 10000), non-positive values refused at boot |
+| T-19.3-05 | Information disclosure | route:list and tests dialing Redis | low | mitigate | only serve calls installCooler; BuildRouter only looks up; TestBuildRouterStoreSmoke |
+| T-19.3-SC | Tampering | Go module installs (go-redis v9.23.0, otter v2.3.0) | high | mitigate | both named in the decision note before install, versions pinned, verified on proxy.golang.org in RESEARCH (Package Legitimacy Audit: OK); miniredis ([ASSUMED] name) is not installed here and waits for plan 05's blocking human check |

+# Phase 19.3 Plan 01: cooler cache and Redis rate-limit store Summary
+
+**New `cooler` module: a Redis fixed-window `surf.Store` (atomic Lua script, per-instance memory fallback) that `serve` publishes before the router, plus `cooler.Cache` with an otter v2 memory driver and a go-redis v9 driver under a per-app key prefix**
+
+## Performance
+
+- **Duration:** 14 min
+- **Started:** 2026-10-15T15:27:12Z
+- **Completed:** 2026-10-15T15:41:00Z
+- **Tasks:** 2 (Task 1 tracer, Task 2 expansion)
+- **Files modified:** 20
+
+## Accomplishments
+
+- Decision note committed first (77dd11c), ahead of the go.mod change (fa4d89d): go-redis v9.23.0, otter v2.3.0, miniredis v2.40.0 test-only (plan 05, after a human check), s3blob behind a build tag (plan 03).
+- `cooler.RateLimitStore`: one Lua script per attempt with `surf.MemoryStore` semantics (first attempt opens the window, denied attempts do not increment, the window never extends), keys `<prefix>rl:<key>`, 500 ms bound, fallback to a per-instance `surf.MemoryStore` with a warning at most once per minute.
+- `serve` calls `installCooler` after `publishUploads` and before `BuildRouter`; `BuildRouter` takes `app.Lookup[Store]()` or falls back to `NewMemoryStore(2*time.Minute)`. `route:list` is unchanged and never dials Redis.
+- `cooler.Cache` (Get, Set, Has, Forget, Remember, Increment, Flush). The memory driver uses otter, bounded by `cache.memory.max_entries` (default 10000). The Redis driver uses SET PX, EXISTS, UNLINK and INCRBY. Its Flush runs SCAN MATCH `<prefix>cache:*` in batches of 500 and removes each batch with UNLINK. It never calls FLUSHDB.
+- `cooler.Install` validates `cache.driver` / `http.rate_limit.store`, shares one Redis client, pings once (warning on failure) and publishes the Cache; `cooler.FromApp` serves jobs and commands lazily.
+- Docs: new `docs/services/caching.md` (order 45), the section "Sharing limits across instances" in `docs/services/rate-limiting.md`, configuration rows, the scaling note, the cooler README in the standard structure, surf README rows, and the root table row.
+

+## Decisions Made
+
+See key-decisions in the frontmatter. All are from the plan's "Claude's discretion" list, except the glob escaping in Flush and the trimmed slug, which are listed under deviations.
+
+## Deviations from Plan
+
+### Auto-fixed Issues
+
+**1. [Rule 3 - Blocking] The docs checker refuses Go code blocks without a `src=` reference**
+- **Found during:** Task 2 (docs/services/caching.md)
+- **Issue:** `TestDocsTree` failed with "go code block has no src= reference" on the caching guide's inline example.
+- **Fix:** Added `modules/cooler/example_test.go` (`ExampleFromApp`, a verified Output) and pointed the guide at it with `src=modules/cooler/example_test.go#ExampleFromApp`, then ran `summer docs:sync`.
+- **Files modified:** modules/cooler/example_test.go, docs/services/caching.md
+- **Verification:** TestDocsTree and `docs:build --check` are green.
+- **Committed in:** fd7f204
+
+**2. [Rule 2 - Missing critical] SCAN MATCH treats the prefix as a pattern**
+- **Found during:** Task 2 (rediscache.go Flush)
+- **Issue:** A `cache.prefix` that contains `*`, `?`, `[` or `]` would let Flush match, and UNLINK, keys of other prefixes.
+- **Fix:** `escapeGlob` escapes those characters before `SCAN MATCH <prefix>cache:*`.
+- **Files modified:** modules/cooler/rediscache.go
+- **Verification:** TestRedisCacheSmoke (a foreign key and the `rl:` key survive Flush).
+- **Committed in:** fd7f204
+
+**3. [Rule 1 - Acceptance gate] The rate-limiting guide did not name `http.rate_limit.store`**
+- **Found during:** Task 1 acceptance criteria (one grep line per file was required).
+- **Issue:** The guide showed only the YAML form (`rate_limit: store: redis`).
+- **Fix:** The guide now names the dotted key and its default. The fix was amended into the unpushed Task 1 commit.
+- **Committed in:** fa4d89d
+
+**4. [Discretion refinement] Prefix slug and helper visibility**
+- The slug of `app.name` also trims `_` at both ends (`Acme!` gives `acme:`, not `acme_:`). This is documented in the README and the caching guide.
+- The prefix helper is unexported (`keyPrefix`) because the plan's artifact list names no exported prefix function.
+
+**5. [Interpretation] Remember after a failed read**
+- When the read fails, Remember runs the callback and returns its value without attempting the write, because the backend that just failed would very likely fail the write too. When the read succeeds with a miss and the write then fails, the failed write is skipped with a warning. Both cases match the plan's degrade rule.
+
+---
+
+**Total deviations:** 3 auto-fixed (1 blocking, 1 missing critical, 1 acceptance gate) plus 2 documented discretion choices.
+**Impact on plan:** No scope creep. The identifiers, keys and behaviour match the plan.
+
+## Issues Encountered
+
+- During a Redis outage each `Attempt` waits up to `AttemptTimeout` (500 ms), because go-redis retries its dial within that bound before cooler falls back. go-redis also prints its own `connection pool: failed to dial` line for every failure, independent of cooler's once-a-minute warning. Both are within the plan (T-19.3-02 accepts a 500 ms bound). Plan 05 or a follow-up could add a short circuit-breaker and fewer dial retries if outage latency matters.
+
+## Known Stubs
+
+None.
+
+## User Setup Required
+
+None. Redis is opt-in through `http.rate_limit.store: redis` / `cache.driver: redis` and `redis.url`.
+
+## Next Phase Readiness
+
+- Plans 02, 03 and 04 can build on this commit. Plan 03 relies on the s3blob entry in the note. Plan 04 adds the site-cache purge to cooler.
+- Plan 05 owns full unit coverage: a miniredis parity table for RateLimitStore against MemoryStore, the outage fallback, the Install/FromApp edge cases and the Flush glob escaping.

+
+## Phase Goal
+
+ROADMAP Goal (not in user-story format; no story is invented, see plan 01): the framework has the transport and infrastructure pieces a multi-client, multi-instance application needs: JWT cookie refresh across subdomains, credentialed CORS, a cache module with a Redis-backed rate-limit store, an S3 blob option, an OpenAPI page and Turnstile verification.
+
+This plan's slice (plan 2 of 5, wave 2): SC-1 and two thirds of SC-3. Cookie transport in bouncer with hardened credentialed CORS (the tracer: a www page refreshes its session on the api host), named CORS profiles, Turnstile verification, and the opt-in /api-docs page.
+
+## Spec-less probe fallback
+
+Skipped visibly: the phase has no requirement IDs to probe, so no probe predicates were generated (see plan 01).
+
+## Decisions taken in this plan (Claude's discretion)
+
+- Cookie builders are methods on `bouncer.CookieConfig`, not guard methods: one config serves every guard, and the refresh window is passed per call (the guard's `refresh_ttl`).
+- `bouncer.LoadCookieConfig` takes `bouncer.CookieConfigSource` (`Lookup`, `String`, `Environment`), which `*compass.Config` satisfies structurally, so bouncer keeps importing no framework module (pattern-mapper flag 1). Apps call it in their plugin Boot and return its error, which fails boot on a bad cookie config.
+- The handlers return `(http.Handler, error)` so missing options are a boot error, not a request-time panic. The refresh handler reads only the cookie (as PHP does); a missing cookie or a refused refresh answers 401 through the writer and leaves the cookie alone. The logout handler revokes through the app's Revoke func when a cookie is present, always sends the forget cookie, and answers 200.
+- CORS profiles live under `http.cors_profiles.<name>`; the middleware name is `cors:<name>`.
+- Turnstile open mode with a secret set: a transport error or timeout is a 422 failure (PHP lets the exception surface as a 500); a missing token is a 422 without a siteverify call (PHP sends it and Cloudflare answers false). A token longer than 2048 characters fails without a call. Both are recorded here as deliberate, outcome-preserving divergences.
+- The default Turnstile error bodies are neutral JSON: 503 `{"error":"turnstile_unavailable"}`, 422 `{"error":"turnstile_failed"}`; an app keeps its PHP envelope by publishing a `bouncer.TurnstileWriter`.
+- The api-docs spec is converted at boot; a spec that does not parse fails boot naming the plugin (PHP answers 500 per request). The page sets a per-request CSP nonce for its one inline script.
+- Plan 02's config keys are documented in the surf and bouncer READMEs and the services pages; the curated key table in docs/setup/configuration.md is left to plans 01 and 03 so wave-2 plans never edit the same file.
+
+## Artifacts this phase produces (this plan)
+
+- `modules/bouncer/cookie.go`: `CookieConfig` (fields `Name`, `Domain`, `Path`, `Secure`, `SameSite`), `CookieConfigSource`, `LoadCookieConfig`, `DefaultCookieName` (`token`), methods `TokenCookie(token string, refreshTTL time.Duration) *http.Cookie` and `ForgetTokenCookie() *http.Cookie`, `CookieResult` (`Status`, `Token`, `Err`), `CookieRefreshOptions` (`Cookie`, `RefreshTTL`, `Refresh`, `Write`), `CookieLogoutOptions` (`Cookie`, `Revoke`, `Write`), `CookieRefreshHandler`, `CookieLogoutHandler`, `ErrNoTokenCookie`.
+- `modules/bouncer/turnstile.go`: `Turnstile` (fields `Secret`, `Production`, `Endpoint`, `Client`), `NewTurnstile`, `TurnstileSiteverifyURL`, `TurnstileTimeout` (5 s), `TurnstileMaxTokenLength` (2048), `DefaultTurnstileField` (`turnstile_token`), `TurnstileVerdict` with `TurnstilePassed`, `TurnstileFailed`, `TurnstileUnavailable`, method `Verify`, method `Middleware`, `TurnstileWriter`.
+- `modules/surf/cors.go`: `LoadCORSProfiles`, validation inside `LoadCORSConfig`, profile middleware and preflight handler; `modules/surf/router.go`: factories `cors` and `turnstile`, OPTIONS routes for profiled routes; `modules/surf/apidocs.go`: `APIDocsProvider`, `SwaggerUIVersion` (`5.33.1`), unexported `mountAPIDocs`.
+- Config keys: `auth.cookie.name`, `auth.cookie.domain`, `auth.cookie.path`, `auth.cookie.secure`, `auth.cookie.same_site`; `http.cors_profiles.<name>.*`; `turnstile.secret`, `turnstile.field`; `http.api_docs.enabled`, `http.api_docs.path`, `http.api_docs.title`.
+- Named middleware `cors:<profile>`, `turnstile:open`, `turnstile:closed`; routes `GET /api-docs` and `GET /api-docs.json` (opt-in).
+- Smoke tests in `modules/surf/transport_smoke_test.go`: `TestCookieRefreshAcrossSubdomainsSmoke`, `TestCORSCredentialsWildcardRefusedSmoke`, `TestCORSProfileSmoke`, `TestTurnstileMiddlewareSmoke`, `TestAPIDocsSmoke`. Full unit coverage is plan 05.
+- Docs: `docs/services/authentication.md` sections "Cookie transport" and "Turnstile"; `docs/services/routing.md` CORS hardening, "CORS profiles", "API documentation page"; bouncer and surf READMEs.
+
+<objective>
+Give the framework cookie-based token refresh across subdomains, credentialed CORS that refuses unsafe configs (globally and per route group), Cloudflare Turnstile verification as middleware, and an opt-in Swagger UI page with its JSON spec, each with README and docs in the same commit.
+
+Purpose: SC-1, the api-docs and Turnstile parts of SC-3, and D-01..D-05, D-16..D-18 (placement per D-19).
+Output: bouncer and surf changes with smoke tests and docs.

+
+Concurrency: plans 19.3-03 and 19.3-04 run in the same wave in this checkout and own other files (lagoon/attach, internal/build, go.mod, cooler, pact, cabana). Before Task 1 run `git status --porcelain -- modules/bouncer modules/surf docs/services/authentication.md docs/services/routing.md`; if it lists a file this plan touches that this plan did not change, stop and report. A transient vet or test failure in a package another wave-2 plan owns is not this plan's: re-run once after a short pause, then report it instead of editing that package. Stage files by explicit path; no co-author tags. PHP reference files live under /media/nvme/dev/jz/wavepath.org; read them for behaviour, never name that application in framework code or docs.

+  <action>bouncer/cookie.go per D-01..D-03: `CookieConfigSource` with `Lookup(path string) (any, bool)`, `String(path string) string`, `Environment() string`. `LoadCookieConfig(src CookieConfigSource) (CookieConfig, error)` reads auth.cookie.name (default DefaultCookieName; must be a valid cookie name), auth.cookie.path (default /; must start with /), auth.cookie.domain (default empty, host-only; a non-empty value must pass (*http.Cookie).Valid, which also catches the silent drop of Pitfall 1), auth.cookie.same_site (lax, strict or none, case-insensitive; default lax), auth.cookie.secure (unset: true exactly when app.url has the https scheme; an explicit false in the production environment is an error, as cabana refuses backend.cookie_secure false); same_site none without Secure is an error. Every error names the key and is prefixed `bouncer:`. `TokenCookie(token, refreshTTL)` sets Name, Value, Path, Domain, MaxAge refreshTTL in whole seconds, Expires now plus refreshTTL, HttpOnly true, Secure and SameSite from the config (D-02: Max-Age is the refresh window). `ForgetTokenCookie()` has the same attributes, an empty value, MaxAge -1 and Expires at Unix 0. `CookieRefreshHandler(opts CookieRefreshOptions) (http.Handler, error)` refuses a nil Refresh or Write or a non-positive RefreshTTL; per request it reads the cookie named opts.Cookie.Name (missing or empty: Write with 401 and ErrNoTokenCookie), calls Refresh(r.Context(), token) (error: Write with 401 and the error, cookie untouched), otherwise http.SetCookie with TokenCookie(newToken, RefreshTTL) and Write with 200 and the new token. `CookieLogoutHandler(opts CookieLogoutOptions) (http.Handler, error)` refuses a nil Revoke or Write; when the cookie is present it calls Revoke and passes a revoke error to Write in the result; it always sets ForgetTokenCookie and writes 200. bouncer gains no framework import.
+
+surf/cors.go per D-04: LoadCORSConfig validates and returns errors naming http.cors keys: supports_credentials true with a * entry in allowed_origins; an allowed_origins_patterns entry that does not compile, or one wrapped in PHP delimiters (# or / at both ends), with a hint to drop the delimiters; it translates an allowed_origins entry containing * (other than the bare *) into an anchored pattern the way php-cors convertWildcardToPattern does (quote the rest, * becomes any characters). Factor pathScopedCORS's per-request logic into an unexported policy type that both the global wrapper and Task 2's profiles reuse. When the origin answer is dynamic (credentials true, any pattern, or more than one listed origin) every response on a CORS path, preflight and disallowed origin included, carries Vary: Origin (combined with the existing preflight Vary values), and an allowed origin is echoed exactly. A non-dynamic config (bare * without credentials, the four apps' setting) keeps today's bytes. BuildRouter already returns LoadCORSConfig's error.
+
+Docs in the same commits: bouncer README (Features, Usage example of an app mounting the refresh handler with RefreshAudienceFor and its own envelope writer, API reference rows for every new identifier, Configuration for auth.cookie.*); docs/services/authentication.md section "Cookie transport" (defaults, why Max-Age is the refresh window, Domain for api and www subdomains and the trust boundary it creates, CSRF note: refresh and logout accept POST only, prefer a JSON body or custom header, SameSite Lax treats sibling subdomains as same-site); docs/services/routing.md CORS section (credentials rules, exact-origin echo and Vary, wildcard entries, pattern errors, the api and www example); surf README Configuration rows updated for the hardened keys.

+  <action>Per D-05. cors.go: `LoadCORSProfiles(cfg *compass.Config) (map[string]CORSConfig, error)` reads every child of http.cors_profiles with the CORSConfig keys; a profile that sets paths is an error; each profile goes through the Task 1 validation with errors naming http.cors_profiles.<name>.<key>; profile names follow the plugin-id character set (lower-case letters, digits, underscore and dash). Add an unexported middleware built from a profile's policy that, for non-OPTIONS requests, sets the same headers the global wrapper sets for an allowed origin (and Vary: Origin when dynamic), and an unexported preflight handler that answers OPTIONS from the profile with writeOptions semantics.
+
+router.go: BuildRouter loads the profiles and registers factory `cors` (plugin surf); wrap validates the param like throttle: an unknown profile fails boot naming the plugin, the route and the profile. compile registers, for every route whose middleware list contains cors:<p>, one `OPTIONS <path>` route on the preflight handler wrapped only in recover and recordPattern (preflights carry no credentials, so no auth, throttle or body middleware); two routes on the same path with different profiles fail boot; a ServeMux conflict surfaces through handleRoute as an error; a profiled route whose path matches a glob of http.cors.paths fails boot with a message saying the global wrapper would answer its preflight first. route:list shows the OPTIONS routes with plugin surf.

+## Trust Boundaries
+
+| Boundary | Description |
+|----------|-------------|
+| browser on a sibling subdomain to the api host | credentialed cross-origin requests and the token cookie |
+| request to Turnstile middleware | untrusted token and body; the siteverify call crosses to Cloudflare |
+| jsDelivr CDN to the api-docs page | third-party scripts executed in the app's origin |
+| config to boot | CORS, cookie, Turnstile and api-docs keys validated before serving |
+
+## STRIDE Threat Register
+
+| Threat ID | Category | Component | Severity | Disposition | Mitigation Plan |
+|-----------|----------|-----------|----------|-------------|-----------------|
+| T-19.3-06 | Information disclosure | surf CORS with credentials and a * origin | high | mitigate | LoadCORSConfig and LoadCORSProfiles refuse the combination at boot; TestCORSCredentialsWildcardRefusedSmoke |
+| T-19.3-07 | Tampering | shared caches storing a CORS answer for another origin | medium | mitigate | Vary: Origin on every dynamic CORS response, preflight and disallowed origin included; exact-origin echo |
+| T-19.3-08 | Spoofing | token cookie attributes (SameSite none without Secure, secure false in production, invalid Domain dropped silently) | high | mitigate | LoadCookieConfig errors for each, with (*http.Cookie).Valid for the domain; httpOnly always on |
+| T-19.3-09 | Information disclosure | cookie Domain covering every subdomain | medium | mitigate | host-only default; Domain is opt-in and the docs name the subdomain trust boundary |
+| T-19.3-10 | Tampering | CSRF on the cookie refresh and logout handlers from a sibling subdomain | low | accept | refresh only rotates a cookie (the answer is unreadable cross-origin unless CORS allows that origin); logout CSRF is a forced logout; POST-only routes and the docs' JSON-or-custom-header advice |
+| T-19.3-11 | Spoofing | Turnstile bypass by an unconfigured secret | high | mitigate | closed mode answers 503 in production with an empty secret; open mode is documented for registration only; with a secret both modes require success true |
+| T-19.3-12 | Denial of service | slow siteverify piling up requests | medium | mitigate | TurnstileTimeout 5 s on the client and the context; at most 4 KiB of the answer read |
+| T-19.3-13 | Tampering | Turnstile middleware consuming the request body | medium | mitigate | the body (already capped) is read once and restored; TestTurnstileMiddlewareSmoke asserts the handler sees it |
+| T-19.3-14 | Information disclosure | Turnstile secret or token in logs and errors | high | mitigate | the secret travels only in the form body; logged errors carry the transport error text without URL, secret or token |
+| T-19.3-15 | Tampering | swagger-ui assets on jsDelivr | medium | mitigate | exact version 5.33.1 with sha384 SRI and crossorigin on all three assets; nonce CSP limits scripts to the nonce and the CDN host |
+| T-19.3-16 | Information disclosure | /api-docs exposing the API surface | low | accept | off by default; the spec is the app's hand-written public surface (D-16); both routes public by design (D-17) |
+| T-19.3-17 | Tampering | XSS through http.api_docs.title or the spec URL | medium | mitigate | html/template contextual escaping for HTML and JS contexts |
+| T-19.3-SC | Tampering | npm/pip/cargo or Go module installs | high | mitigate | this plan installs nothing: swagger-ui-dist is loaded from the CDN at a pinned version with SRI (5.33.2 flagged too new is avoided); go.mod and go.sum unchanged |

+  - "LoadCookieConfig takes bouncer.CookieConfigSource (Lookup, String, Environment), which *compass.Config satisfies; bouncer still imports no framework module"
+  - "Cookie handlers return (http.Handler, error) so missing options fail boot; refresh reads only the cookie and leaves it alone on 401; logout always clears the cookie and answers 200, passing a revoke error to the writer"
+  - "A CORS answer is dynamic with credentials, any pattern (wildcard origins included) or more than one origin; dynamic answers always carry Vary: Origin; the non-credentialed * answer is byte-identical to before"
+  - "CORS profiles live under http.cors_profiles.<name> (names [a-z0-9_-]+); the router registers OPTIONS routes owned by surf; overlap with http.cors.paths fails boot"
+  - "Turnstile divergences from PHP (outcome-preserving): open mode with a secret treats a transport error or timeout as 422 (PHP surfaces a 500); a missing token is 422 without a siteverify call; tokens over 2048 characters fail without a call"
+  - "Default Turnstile bodies are neutral JSON ({\"error\":\"turnstile_unavailable\"} 503, {\"error\":\"turnstile_failed\"} 422); a published bouncer.TurnstileWriter keeps an app's envelope; a published *bouncer.Turnstile replaces the config-built verifier"

+# Phase 19.3 Plan 02: Cookie transport, credentialed CORS, Turnstile and API docs Summary
+
+**httpOnly token-cookie refresh across subdomains in bouncer, boot-validated credentialed CORS with per-group cors:<profile> policies and router-registered preflights, Cloudflare Turnstile as turnstile:open|closed middleware, and an opt-in /api-docs Swagger UI page pinned to swagger-ui-dist 5.33.1 with SRI**
+
+## Performance
+
+- **Duration:** 15 min
+- **Started:** 2026-10-15T15:45:56Z
+- **Completed:** 2026-10-15T16:00:55Z
+- **Tasks:** 4
+- **Files modified:** 11
+
+## Accomplishments
+
+- Cookie transport (D-01..D-03): `bouncer.LoadCookieConfig` reads `auth.cookie.{name,domain,path,secure,same_site}` with PHP defaults (token, `/`, HttpOnly, Lax, host-only, Secure when `app.url` is https) and refuses an invalid domain, `none` without Secure and `secure: false` in production. `bouncer.CookieConfig.TokenCookie` sets Max-Age to the refresh window. `bouncer.CookieRefreshHandler` and `bouncer.CookieLogoutHandler` wrap the app's refresh or revoke func and writer.
+- CORS hardening (D-04): `surf.LoadCORSConfig` refuses credentials with `*`, uncompilable patterns and PHP-delimited patterns, naming the key. Wildcard origins become anchored patterns. Dynamic answers echo the exact origin and always send `Vary: Origin`. `TestCORSOptionsMatchesLaravel` is still green.
+- CORS profiles (D-05): `surf.LoadCORSProfiles` reads `http.cors_profiles.<name>` and the `cors:<profile>` factory applies them. The router registers an `OPTIONS` route (owner `surf`) per profiled path. Boot errors cover an unknown profile, conflicting profiles, an existing OPTIONS route and overlap with `http.cors.paths`.
+- Turnstile (D-18): `bouncer.Turnstile.Verify` follows PHP's open and closed modes, with a 5 s bound, a 4 KiB answer cap and the 2048-character token limit. `bouncer.Turnstile.Middleware` reads the token from the query, a JSON body or a form body and restores the body. surf registers `turnstile:open|closed` from `turnstile.secret` (`SUMMER_TURNSTILE__SECRET`) and `turnstile.field`, using the trusted-proxy client IP.
+- API docs (D-16, D-17): `surf.APIDocsProvider` and `http.api_docs.{enabled,path,title}` mount public `GET /api-docs` and `/api-docs.json`. The spec is converted once at boot. The page pins swagger-ui-dist `5.33.1`, carries sha384 SRI on all three assets (re-verified against jsDelivr during execution) and uses a nonce CSP.
+
+## Task Commits

+
+## Config keys and identifiers added
+
+- Keys: `auth.cookie.name`, `auth.cookie.domain`, `auth.cookie.path`, `auth.cookie.secure`, `auth.cookie.same_site`; `http.cors_profiles.<name>.*`; `turnstile.secret`, `turnstile.field`; `http.api_docs.enabled`, `http.api_docs.path`, `http.api_docs.title`.
+- Middleware: `cors:<profile>`, `turnstile:open`, `turnstile:closed`. Routes: `GET /api-docs`, `GET /api-docs.json` (opt-in), plus `OPTIONS <path>` per profiled path.
+- bouncer: `CookieConfig`, `CookieConfigSource`, `LoadCookieConfig`, `DefaultCookieName`, `CookieResult`, `CookieRefreshOptions`, `CookieLogoutOptions`, `CookieRefreshHandler`, `CookieLogoutHandler`, `ErrNoTokenCookie`, `Turnstile`, `NewTurnstile`, `TurnstileSiteverifyURL`, `TurnstileTimeout`, `TurnstileMaxTokenLength`, `DefaultTurnstileField`, `TurnstileVerdict` (`TurnstilePassed`, `TurnstileFailed`, `TurnstileUnavailable`), `TurnstileWriter`.
+- surf: `LoadCORSProfiles`, `APIDocsProvider`, `SwaggerUIVersion`.
+
+## Decisions Made
+
+See `key-decisions` in the frontmatter. The divergences from PHP are deliberate:
+
+- Credentials with `*` is a boot error (php-cors reflects any origin).
+- In Turnstile open mode with a secret, a transport error or timeout is a 422 (PHP surfaces a 500).
+- A missing Turnstile token, or one over 2048 characters, is a 422 without a siteverify call.
+- A spec that does not convert fails boot (PHP answers 500 per request).
+- The Swagger UI version is exact and SRI-checked (PHP loads the floating `@5` without integrity).
+
+## Deviations from Plan
+
+### Auto-fixed Issues
+
+**1. [Rule 3 - Blocking] A published `*bouncer.Turnstile` overrides the config-built verifier**
+- **Found during:** Task 3
+- **Issue:** The smoke test must point the verifier's `Endpoint` at an httptest fake, but BuildRouter builds the verifier from config, so the test had no way to reach it.
+- **Fix:** `buildTurnstile` uses a `*bouncer.Turnstile` published on the app when there is one. Otherwise it builds from `turnstile.secret`. This is documented in the surf README and the Turnstile section.
+- **Files modified:** modules/surf/router.go, docs
+- **Committed in:** 597c79b
+
+**2. [Rule 2 - Missing critical] Turnstile middleware handles a body read error**
+- **Found during:** Task 3
+- **Issue:** The plan had the middleware read the whole body but said nothing about a read error, such as the router's body cap tripping.
+- **Fix:** An `*http.MaxBytesError` answers 413 and any other read error answers 400, both through the writer with `TurnstileFailed`. The handler is never called with a broken body.
+- **Committed in:** 597c79b
+
+**3. [Rule 3 - Blocking] Docs checker requires Go blocks to come from tested code**
+- **Found during:** Task 2 and Task 4
+- **Issue:** A Go code block in docs/ must carry a `src=` reference to a function a Test or Example runs.
+- **Fix:** The CORS profile group example became prose. For the API docs page, `BlogPlugin.APIDocsSpec` and `ExampleAPIDocsProvider` (with `// Output:`) were added to `modules/surf/example_test.go`, which is not in the plan's file list. `TestDocsDeclarations` calls the method.
+- **Committed in:** 20bc1a0
+
+**4. [Rule 2] Small hardening and accuracy additions**
+- Zero-value `CookieConfig` fields default to Name `token` and Path `/` in the builders and handlers.
+- Turnstile `success:false` with Cloudflare error codes (sanitized) is logged at debug; transport failures are logged at warn.
+- `validatorUrl: null` in the Swagger config, so the spec URL is never sent to swagger.io.
+- docs/services/routing.md's middleware table gained the turnstile row in Task 3 (routing.md was not in Task 3's file list).
+- The surf README's standard-library list gained `log/slog` and `net/url`, which were missing before this plan.
+- **Committed in:** e7659f2, 597c79b, 20bc1a0
+
+---
+
+**Total deviations:** 4 (2 Rule 3, 2 Rule 2).
+**Impact on plan:** None of these change behaviour the plan specified. The two seams it adds (a published verifier, the example test) are small and documented.
+
+## Issues Encountered
+
+None.
+
+## User Setup Required
+
+None. Apps opt in through config (`auth.cookie.*`, `http.cors_profiles`, `SUMMER_TURNSTILE__SECRET`, `http.api_docs.enabled`).
+
+## Next Phase Readiness
+
+- Plan 05 (unit tests) has full coverage to write for cookie.go, turnstile.go, cors.go (profiles, wildcard origins, PHP-delimited patterns) and apidocs.go. The smoke tests here are the starting point.
+- Human UAT: check that the Swagger UI page renders in a browser under its CSP (D6), and that the cookie survives across real subdomains (D7).
+
+## Self-Check: PASSED
+
+- FOUND: modules/bouncer/cookie.go, modules/bouncer/turnstile.go, modules/surf/apidocs.go, modules/surf/transport_smoke_test.go
+- FOUND commits: e7659f2, 5055e8b, 597c79b, 20bc1a0
+- `go vet ./...` and `go test -short ./...` green; five smoke tests plus TestCORSOptionsMatchesLaravel pass; TestDocsTree and `docs:build --check` green
+- bouncer imports no SummerCMS module; no "wavepath" in modules/bouncer, modules/surf or docs/services

+
+## Phase Goal
+
+ROADMAP Goal (not in user-story format; no story is invented, see plan 01): the framework has the transport and infrastructure pieces a multi-client, multi-instance application needs: JWT cookie refresh across subdomains, credentialed CORS, a cache module with a Redis-backed rate-limit store, an S3 blob option, an OpenAPI page and Turnstile verification.
+
+This plan's slice (plan 3 of 5, wave 2): the S3 part of SC-3 and the folded stored-XSS todo. `summer.yaml` gains `build.tags`, the `summercms_s3` tag links the s3blob driver (the tracer: tagged binary opens s3://, untagged binary names the tag), then the disk-name extension fix and `storage.uploads.public_url`.
+
+## Spec-less probe fallback
+
+Skipped visibly: the phase has no requirement IDs to probe, so no probe predicates were generated (see plan 01).
+
+## Decisions taken in this plan (Claude's discretion)
+
+- The build tag is `summercms_s3` (exported as `attach.S3BuildTag` for docs and errors). summer.yaml declares it as a list under `build.tags`; each tag must match `^[a-z0-9_]+$`, duplicates are dropped, and the tags are passed to go build as one `-tags=` argument (exec args, no shell). `summer build` prints a `build tags: …` line, because app build scripts that run a second raw `go build` must repeat the tag (Pitfall 6); the boot error is the safety net.
+- `DiskExtension` follows RESEARCH Pattern 6: a table of specific sniffed types with their accepted extension sets (the client's extension is kept when it belongs to the set, else the canonical one); every other sniff counts as generic and keeps the client's extension unless it is script-capable, which becomes `txt` for a text/* sniff and `bin` otherwise. It never calls `mime.ExtensionsByType` (host-dependent). Store passes the sniffed type before its extension-based fallback.
+- `public_url` applies to every URL the package builds, as D-12 states; the start-up warning and the docs carry the "public files only" rule instead of a narrower per-file switch.
+- The bucket-open error keeps quoting bucket_url (credentials never travel in it per D-14).
+
+<assumption_delta_decision>
+add-alongside: blob drivers pluralize from file and mem to file, mem and s3. fileblob and memblob stay linked in every binary; s3blob is added only to binaries built with the summercms_s3 tag, so binaries without the tag keep their size and dependency set.
+</assumption_delta_decision>
+
+## Artifacts this phase produces (this plan)
+
+- `internal/build`: `Manifest.Tags`, `ValidateBuildTag`, unexported `goBuildArgs(binRel string, tags []string) []string`; `summer.yaml` key `build.tags`; the `build tags:` output line.
+- `modules/lagoon/attach`: `S3BuildTag` (`summercms_s3`), files `s3_on.go` (`//go:build summercms_s3`, blank import of `gocloud.dev/blob/s3blob`) and `s3_off.go` (`//go:build !summercms_s3`), unexported `s3Enabled`; `DiskExtension(contentType, clientExt string) string`; `PublicURLBase() string`; config key `storage.uploads.public_url`.
+- Dependencies: AWS SDK v2 modules as indirect requirements of `gocloud.dev/blob/s3blob` (named in plan 01's decision note).
+- Smoke tests in `internal/build/manifest_tags_smoke_test.go` (`TestManifestBuildTagsSmoke`) and `modules/lagoon/attach/infra_smoke_test.go` (`TestOpenBucketS3Smoke` in both tag modes, `TestStoreDiskExtensionSmoke` on Postgres, `TestPublicURLSmoke`). Full unit coverage is plan 05.
+- Docs: `docs/services/storage.md` sections "S3 and S3-compatible buckets", "Public URL base" and a deploy note; `docs/database/attachments.md` disk names; `docs/architecture/go-modules-and-workspaces.md` `build.tags`; `docs/console/scaffolding.md`; rows in `docs/setup/configuration.md`; the shared-uploads note in `docs/architecture/performance-and-scaling.md`; lagoon README.
+
+<objective>
+Let an application choose an S3 (or S3-compatible) uploads bucket from config through a summer.yaml build tag, give it a public URL base for a bucket or CDN, and close the stored-XSS hole where a disk name kept the client's extension, each documented in the same commit.
+
+Purpose: SC-3's S3 driver, D-12..D-15 (placement per D-19), and the folded todo `2026-10-11-uploads-keep-client-extension-stored-xss`.
+Output: internal/build and lagoon/attach changes with smoke tests and docs.

+Concurrency: plans 19.3-02 and 19.3-04 run in the same wave in this checkout and own other files (bouncer, surf, cooler, pact, cabana). This plan is the only wave-2 plan that changes go.mod and go.sum. Before Task 1 run `git status --porcelain -- go.mod go.sum internal/build modules/lagoon docs/services/storage.md docs/database docs/architecture docs/console docs/setup`; if it lists a file this plan touches that this plan did not change, stop and report. A transient vet or test failure in a package another wave-2 plan owns is not this plan's: re-run once after a short pause, then report it. Stage files by explicit path; no co-author tags. Docker-backed smoke tests skip under `-short`; run them on a Docker host (`sudo -u golem` when the socket is denied) and record NOT RUN in the SUMMARY when no daemon answers. No real S3 or MinIO is available: the s3 smoke opens the bucket only (s3blob opens lazily); a real upload stays a manual UAT item (19.3-VALIDATION.md).

+<interfaces>
+Existing seams (read; extend, do not fork):
+
+- `internal/build/manifest.go`: `Manifest{Module, Binary, Plugins}`, `LoadManifest` (koanf yaml parser into a tree; `asString`, `asSlice`, `asMap`), `SaveManifest` (writes module, binary and plugins only, lines :90-103, so a new key is dropped by `plugin:add` unless written here).
+- `internal/build/build.go` :49: `exec.CommandContext(ctx, "go", "build", "-o", binRel, ".")`; `internal/dev/watch.go` :46 reuses `build.App`.
+- `modules/lagoon/attach/bucket.go`: blank imports of fileblob and memblob (:13-14), `normalizeBucketURL` (unknown schemes pass through unchanged), `OpenBucket` (records public_path_prefix through `setPublicPathPrefix` under `prefixMu`), error style `attach: … (set SUMMER_…)`.
+- `modules/lagoon/attach/store.go` :124-152: client extension allow-list, `contentType := baseMediaType(http.DetectContentType(head))`, the octet-stream fallback to `mime.TypeByExtension`, `newDiskName(ext)`.
+- `modules/lagoon/attach/thumb.go` :83-99: `PublicURL(key)` and `(*File).URL()`; `Thumb`/`ThumbKey` write thumbnails eagerly, so their URLs work behind a bucket or CDN base too.
+- `modules/lagoon/attach/store_test.go` `TestStoreSmoke` (:48): the Postgres harness and `testing.Short()` skip to reuse.

+  <action>Per D-13 and D-14.
+
+internal/build: Manifest gains `Tags []string`. LoadManifest reads the optional `build` mapping and its `tags` list (a non-mapping build or a non-list tags is an error naming build.tags); every entry is trimmed and checked by `ValidateBuildTag(tag string) error` (pattern ^[a-z0-9_]+$, error names the tag); duplicates are dropped keeping the first. SaveManifest writes a `build:` block with `tags:` entries after plugins when Tags is non-empty, validating each, so `summer plugin:add` keeps them. `goBuildArgs(binRel string, tags []string) []string` returns build, then -tags=<comma-joined> when tags exist, then -o binRel and the package dot; App uses it and, when tags exist, prints `build tags: <comma list>` to out before building.

+attach: move the s3 driver behind the tag: s3_on.go (constraint summercms_s3) blank-imports gocloud.dev/blob/s3blob and sets the unexported constant s3Enabled to true; s3_off.go (constraint not summercms_s3) sets it to false. bucket.go exports `S3BuildTag` = summercms_s3 and, in OpenBucket after normalizeBucketURL, refuses an s3 scheme (case-insensitive) when s3Enabled is false with an error that starts with `attach: storage.uploads.bucket_url uses s3://` and names S3BuildTag, `build.tags` in summer.yaml and the `-tags summercms_s3` flag (or GOFLAGS) for a raw go build. Run `go mod tidy` (it adds the AWS SDK v2 modules s3blob needs as indirect requirements); nothing outside the tagged file imports s3blob.
+
+Docs in the same commit: docs/services/storage.md section "S3 and S3-compatible buckets" (the summer.yaml build.tags example, the boot error, raw go build users add -tags summercms_s3, a bucket_url for AWS and one for an S3-compatible endpoint with region, endpoint, use_path_style and the two checksum parameters, credentials from AWS_ACCESS_KEY_ID, AWS_SECRET_ACCESS_KEY or a profile, never in config, and that the existing /storage/uploads route also serves an S3 bucket); docs/architecture/go-modules-and-workspaces.md manifest example and text for build.tags; docs/console/scaffolding.md summer build and summer.yaml rows mention build tags; docs/setup/configuration.md storage.uploads.bucket_url row lists s3:// with the tag; docs/architecture/performance-and-scaling.md says shared uploads can also be an S3 bucket; lagoon README attach bullet and API row for S3BuildTag.

The helper never asks package mime for extensions (its answer depends on the host's mime tables). store.go: keep the sniffed base type in its own variable before the octet-stream fallback, and name the blob with newDiskName(DiskExtension(sniffed, ext)); file_name, the allow-list check and the stored content_type rule are unchanged.

+# Phase 19.3 Plan 03: S3 build tag, content-derived disk names and public_url Summary
+
+**`summer.yaml` `build.tags` with the `summercms_s3` tag that links gocloud's s3blob only into tagged binaries (untagged ones name the tag at boot), `attach.DiskExtension` so a PNG uploaded as `x.html` is stored and served as `.png`, and `storage.uploads.public_url` for direct bucket or CDN file URLs**
+
+## Performance
+
+- **Duration:** 10 min
+- **Started:** 2026-10-15T16:03:46Z
+- **Completed:** 2026-10-15T16:13:06Z
+- **Tasks:** 3 (Task 1 tracer, Tasks 2 and 3 expansion)
+- **Files modified:** 20
+
+## Accomplishments
+
+- `internal/build`: `Manifest.Tags` read from the optional `build.tags` list (trimmed, `ValidateBuildTag` against `^[a-z0-9_]+$`, duplicates dropped, a non-mapping `build` or non-list `tags` is an error naming `build.tags`). `SaveManifest` writes the `build:` block after the plugins, so `summer plugin:add` keeps it. `goBuildArgs` puts `-tags=<comma list>` before `-o`, and `App` prints `build tags: …`. `summer dev` inherits this through `build.App`.
+- `attach`: `s3_on.go` (`//go:build summercms_s3`) is the only importer of `gocloud.dev/blob/s3blob`. `OpenBucket` refuses an `s3://` URL (case-insensitive scheme) in an untagged binary. The error starts with `attach: storage.uploads.bucket_url uses s3://` and names `summercms_s3`, `build.tags` in summer.yaml, `-tags summercms_s3` and `GOFLAGS`. No `s3.*` keys exist. The S3 configuration lives in the gocloud `bucket_url` query, and credentials come from the AWS environment.
+- `attach.DiskExtension(contentType, clientExt)` uses a fixed table of 22 specific sniffed types and a list of script-capable extensions. `Store` names the blob with `newDiskName(DiskExtension(sniffed, ext))`. `file_name`, the allow-list and the stored `content_type` rule are unchanged.
+- `storage.uploads.public_url`: OpenBucket validates and records it (`PublicURLBase()`) next to the path prefix under `prefixMu` and logs one info line naming the host and the public-files-only rule. `PublicURL` (and therefore `File.URL` and thumbnail URLs) uses the base when it is set. Otherwise the URLs are unchanged.
+- Docs: `docs/services/storage.md` gained the sections "S3 and S3-compatible buckets" and "Public URL base", a deploy note on nosniff and allow-lists, and an s3 row in the bucket URL table. Also updated: the disk-name paragraph and URL sentence in `attachments.md`, `build.tags` in `go-modules-and-workspaces.md`, the `summer build`/`summer dev`/`summer.yaml` rows in `scaffolding.md`, the `bucket_url` and `public_url` rows in `configuration.md`, the shared-uploads note in `performance-and-scaling.md`, and the lagoon README (overview, features, API rows `S3BuildTag`, `DiskExtension`, `PublicURLBase`, `PublicURL`, `OpenBucket`, `Store`, config rows, dependencies).
+
+## Task Commits
+
+1. **Task 1 (tracer): build.tags and the summercms_s3 S3 driver tag** - `2382040` (feat)
+2. **Task 2: content-derived disk names through attach.DiskExtension** - `2e22e9f` (fix)
+3. **Task 3: storage.uploads.public_url** - `2e87efa` (feat)
+
+**Plan metadata:** the final docs(19.3-03) commit.
+
+## Identifiers and keys added
+
+- internal/build: `Manifest.Tags`, `ValidateBuildTag`, unexported `goBuildArgs(binRel string, tags []string) []string` and `loadBuildTags`; summer.yaml key `build.tags`; output line `build tags: <list>`.
+- attach: `S3BuildTag` (`summercms_s3`), unexported `s3Enabled` and `checkS3Driver`; `DiskExtension`; `PublicURLBase`, unexported `setPublicURLBase` and `parsePublicURL`; config key `storage.uploads.public_url` (env `SUMMER_STORAGE__UPLOADS__PUBLIC_URL`).
+- Tests: `TestManifestBuildTagsSmoke`, `TestOpenBucketS3Smoke` (both tag modes), `TestStoreDiskExtensionSmoke` (Postgres), `TestPublicURLSmoke`.
+
+## go.mod additions
+
+`go mod tidy` added indirect requirements only: `github.com/aws/aws-sdk-go-v2` v1.41.9 with `config`, `credentials`, `feature/ec2/imds`, `feature/s3/transfermanager`, `internal/configsources`, `internal/endpoints/v2`, `internal/v4a`, `aws/protocol/eventstream`, `service/s3` v1.102.2, `service/internal/{accept-encoding,checksum,presigned-url,s3shared}`, `service/{signin,sso,ssooidc,sts}`, `github.com/aws/smithy-go` v1.26.0 and `github.com/google/wire` v0.7.0. go.sum also gained hashes for `google/go-replayers` and `google/martian/v3` (test-only modules of gocloud). None of them is linked into a binary without the tag. `grep -rln gocloud.dev/blob/s3blob` over modules, internal and cmd lists only `s3_on.go`.
+
+## Docker smoke tests
+
+Run on this host (the Docker daemon answered): `TestStoreDiskExtensionSmoke` PASS (postgres:16-alpine). The non-short `go test ./modules/lagoon/...` run after Task 2 was green, and so were the non-short `TestPublicURL|TestFileURL|TestStatic|TestOpenBucket` runs after Task 3. No real S3 or MinIO was available: the S3 smoke only opens the bucket (s3blob connects lazily), so a real upload stays a manual UAT item (19.3-VALIDATION.md).
+
+## Verification
+
+- Task 1: `go vet ./...` and `go vet -tags summercms_s3 ./modules/lagoon/...` pass. `go build -tags summercms_s3 ./...` passes. Both smokes passed in both tag modes, and the short suites and TestDocsTree passed.
+- Task 2: vet, the lagoon short suites, the Postgres regression smoke and TestDocsTree passed.
+- Task 3: both smokes passed (2 PASS lines). The whole `go test -short ./...` run, TestDocsTree and `summer docs:build --check` ("no problems found") passed.
+- Wave sampling: `go vet -tags summercms_s3 ./modules/lagoon/... && go test -short -tags summercms_s3 ./modules/lagoon/attach` is green.
+
+## Decisions Made
+
+See key-decisions in the frontmatter. All come from the plan's "Claude's discretion" list.
+
+## Deviations from Plan
+
+### Auto-fixed Issues
+
+**1. [Rule 3 - Blocking] The Store regression smoke lives in store_test.go, not infra_smoke_test.go**
+- **Found during:** Task 2
+- **Issue:** The Postgres harness `attachGorm` is in the external test package `attach_test` (lifecycle_test.go). `infra_smoke_test.go` has to be in the internal package `attach`, because `TestOpenBucketS3Smoke` reads the unexported `s3Enabled` and `TestPublicURLSmoke` resets the package URL state. A file cannot belong to both packages.
+- **Fix:** `TestStoreDiskExtensionSmoke` is appended to `modules/lagoon/attach/store_test.go` next to `TestStoreSmoke`, whose harness it reuses. The test name and the `-run` filter in the plan's verify command are unchanged. PATTERNS.md suggested this file too.
+- **Files modified:** modules/lagoon/attach/store_test.go
+- **Committed in:** 2e22e9f
+
+**2. [Rule 1 - Acceptance gate] A comment in bucket.go named the s3blob import path**
+- **Found during:** Task 1 acceptance criteria (only `s3_on.go` may mention `gocloud.dev/blob/s3blob`)
+- **Fix:** The `S3BuildTag` doc comment now says "s3blob, imported only by s3_on.go". The fix was made before the Task 1 commit.
+- **Committed in:** 2382040
+
+**3. [Rule 2 - Hardening] DiskExtension normalises its inputs**
+- **Found during:** Task 2
+- **Issue:** `DiskExtension` is exported, and the deferred app call sites will pass `filepath.Ext` output and raw content types.
+- **Fix:** It strips media-type parameters, lower-cases both inputs and trims a leading dot. A client extension that fails the `[a-z0-9]{1,10}` pattern falls back to `txt` or `bin` like a script-capable one. `Store`'s inputs are already normalised, so its behaviour does not change.
+- **Committed in:** 2e22e9f
+
+### Notes
+
+- `github.com/google/wire` v0.7.0 is an indirect requirement of s3blob that the plan 01 decision note does not name (the note names the AWS SDK v2 modules). It comes with the already-required gocloud.dev v0.46.0 and is linked only under the tag.
+- The Task 3 acceptance grep for consumer names over `modules/lagoon` matches three pre-existing test files that this plan does not touch. This plan added no matching line (`git diff` count 0). The finding is logged in `deferred-items.md`, together with a pre-existing gofmt issue in `internal/build/registry.go`.
+
+---
+
+**Total deviations:** 3 auto-fixed (1 blocking, 1 acceptance gate, 1 hardening).
+**Impact on plan:** None on scope. The identifiers, keys and behaviour match the plan.
+
+## Issues Encountered
+
+None.
+
+## Known Stubs
+
+None.
+
+## Threat Flags
+
+None. All new surface is in the plan's threat register: T-19.3-18 to T-19.3-22 and T-19.3-SC.
+
+## User Setup Required
+
+None for the framework. An app that switches to S3 adds `summercms_s3` under `build.tags`, sets an `s3://` `bucket_url` and provides AWS credentials in the environment. An app with a second raw `go build` in its build script must also add `-tags summercms_s3` there.
+
+## Next Phase Readiness
+
+- Plan 05 owns full unit coverage: a `DiskExtension` table test (every table type, the script-capable list, input normalisation), `ValidateBuildTag` and loader edge cases (non-mapping `build`, non-list `tags`), and `parsePublicURL` cases.
+- Follow-up outside this phase: move the app upload call sites (`storeUpload`, `StorePublicFile`) to `attach.DiskExtension`. The app build script needs `-tags summercms_s3` when the app moves to S3.

+
+## Phase Goal
+
+ROADMAP Goal (not in user-story format; no story is invented, see plan 01): the framework has the transport and infrastructure pieces a multi-client, multi-instance application needs: JWT cookie refresh across subdomains, credentialed CORS, a cache module with a Redis-backed rate-limit store, an S3 blob option, an OpenAPI page and Turnstile verification.
+
+This plan's slice (plan 4 of 5, wave 2): the folded site-cache purge todo (D-10, D-11). The Journal-only purger becomes a framework service in `cooler`; the FAQ plugin and vue-faq-layer prove it end to end (the tracer), cabana gains a reorder hook so the menu plugin purges after saves, deletes and reorders, Journal moves onto the service with alias keys, the shared Nuxt route lands in all three layers, and, after the human's go-ahead, the app pointers move.
+
+## Spec-less probe fallback
+
+Skipped visibly: the phase has no requirement IDs to probe, so no probe predicates were generated (see plan 01).
+
+## Decisions taken in this plan (Claude's discretion)
+
+- Identifiers: `cooler.SiteCachePurger`, `cooler.NewSiteCachePurger(purgeURL, token)` (errors name the framework keys), `cooler.NewSiteCachePurgerFor(urlKey, tokenKey, purgeURL, token)` (errors name the given keys, used by the Journal alias path), `cooler.PurgeSiteCacheAfterCommit`, `cooler.SiteCacheFromApp`, constants `SiteCachePurgeURLKey`, `SiteCachePurgeTokenKey`, `SiteCachePurgeTimeout`, `SiteCachePurgeMinTokenLength`.
+- Purge kinds: `faq` (slug = the FAQ slug), `menu` (slug = the menu code), `menu_entry` (slug = the entry id, or `partition:<id>` for a reorder), Journal keeps `post` and `category`. The Nuxt route purges every route-cache entry regardless of kind; the kind only reaches its log line.
+- The hook is `pact.ReorderAfterSave` with `ReorderAfterSave(ctx context.Context, partition *uint64) error`, the reorder request's partition, so a partitioned reorder (menu entries per menu) can name what changed.
+- The shared Nuxt helper lives in `server/lib/siteCachePurge.ts`, outside Nitro's and Nuxt's auto-import directories, so three layers can carry the same exports without duplicate auto-import warnings; the route imports it by relative path. Its exported names differ from the Journal layer's `app/utils/siteCache.ts` (kept unchanged for the alias route).
+- Layer releases are additive minors: vue-faq-layer 0.2.0, vue-menu-layer 0.2.0, vue-journal-layer 0.4.0. Plugin repos get no tag (apps mount them as submodules). Plugin go.mod require lines stay on the current framework tag; the plugins build through their checked-in go.work replace until plan 05's release decision tags the framework.
+- Only `sm-grzybyfunkcjonalne-app` gets pointer bumps here: it mounts all three plugins and its pointers sit at the plugins' pre-adoption heads. `sm-summercmsio-app` mounts Journal at a commit 45 commits behind main, so its bump is a separate follow-up recorded in the SUMMARY, not part of this phase.
+
+## Artifacts this phase produces (this plan)
+
+- `modules/cooler/sitecache.go`: the identifiers listed in Decisions; config keys `site_cache.purge_url` (SUMMER_SITE_CACHE__PURGE_URL) and `site_cache.purge_token` (SUMMER_SITE_CACHE__PURGE_TOKEN); `Install` publishes the purger.
+- `modules/pact/capabilities.go`: `pact.ReorderAfterSave`; `modules/cabana/reorder.go` calls it inside the reorder transaction.
+- Plugins: FAQ `FormAfterCreate`/`FormAfterUpdate` (purge appended) and `FormAfterDelete`; menu `menusAdminController` with an app accessor and `FormAfterCreate`/`FormAfterUpdate`/`FormAfterDelete`; `menuEntriesAdminController` `FormAfterDelete` and `ReorderAfterSave`; a `purgeSiteCache` helper in each plugin's controllers package; Journal alias wiring and `classes` aliases.
+- Layers: `server/lib/siteCachePurge.ts` (`MIN_SITE_PURGE_TOKEN_LENGTH`, `SITE_ROUTE_CACHE_BASE`, `authorizeSitePurge`, `purgeSiteRouteCache`, `parseSitePurgeEvent`), `server/api/__site__/cache/purge.post.ts`, runtimeConfig `siteCache.purgeToken`, route rule `/api/__site__/**`, specs `tests/sitePurge.test.ts` (names start with `sitePurge:`), versions 0.2.0 / 0.2.0 / 0.4.0, tags `v0.2.0` (faq, menu) and `v0.4.0` (journal) on the human's reply.
+- Tests: `modules/cooler/sitecache_test.go` (the Journal purger tests ported: `TestSiteCachePurgeConfig`, `TestSiteCachePurgeRequest`); `TestFaqAdminPurgesSiteCache` and `TestMenuAdminPurgesSiteCache` (Postgres) in the plugins. Full unit coverage is plan 05.
+- Docs: `docs/services/caching.md` section "Site cache purge"; cooler README and root README summary sentence; pact and cabana READMEs; `docs/backend/admin-controllers.md` hook table row; `docs/backend/lists-and-filters.md` reorder hook note; plugin and layer READMEs.
+
+<objective>
+Turn the Journal-only site-cache purge into a framework service that every admin save can use, adopt it in the FAQ, menu and Journal plugins (with a new reorder hook in cabana) and ship the shared Nuxt purge route in all three layers, committing framework first, then plugin and layer repos, pushing only on the human's go-ahead, then moving the app pointers.
+
+Purpose: D-10 and D-11 (the folded todo `site-cache-purge-for-menu-and-faq`), placement per D-19, docs per SC-4.
+Output: commits in summercms.go, three plugin repos, three layer repos and, after the reply, the app and its vue app.

+Repositories (all siblings of summercms.go under /media/nvme/dev/golem15/summercms.io/summercms): sm-faq-plugin (main 919cf06 at planning time), sm-menu-plugin (main 9c0f833), sm-journal-plugin (main 31d901c, tags up to v0.1.1), vue-faq-layer (main 321bc90, v0.1.0), vue-menu-layer (main 2deac88, v0.1.0), vue-journal-layer (main 25e9bfe, v0.3.0), sm-grzybyfunkcjonalne-app (submodules plugins/golem15/{journal,menu,faq} and vue-grzybyfunkcjonalne-app, which pins the three layers by tag in package.json). Each plugin's checked-in go.work replaces summercms with ../summercms.go, so plugin tests compile against this checkout. Layers run `node --test` through `pnpm --dir <layer> test`.
+
+Concurrency and commit rules: plans 19.3-02 and 19.3-03 run in the same wave in summercms.go and own other files. Phase 18.1 plan 08 (pending at planning time) edits modules/pact/capabilities.go, modules/cabana/crud.go, the pact and cabana READMEs and docs/backend/admin-controllers.md; Task 2 asserts a clean tree for those paths first. Commit in each repo separately, staging by explicit path, no co-author tags; never stage files inside a submodule from the app repo; use `ssu` for submodule pointer work in the app. The framework commit of a task lands before the plugin or layer commit that uses it. Nothing is pushed or tagged before the Task 4 reply. Docker-backed tests skip under `-short`; run them on a Docker host (`sudo -u golem` when the socket is denied) and record NOT RUN in the SUMMARY when no daemon answers.

+  <action>Framework first (one summercms.go commit, README and docs included), per D-10. modules/cooler/sitecache.go: move the Journal purger nearly verbatim with these changes: key constants SiteCachePurgeURLKey = site_cache.purge_url and SiteCachePurgeTokenKey = site_cache.purge_token; NewSiteCachePurger(purgeURL, token) delegates to NewSiteCachePurgerFor(SiteCachePurgeURLKey, SiteCachePurgeTokenKey, purgeURL, token), whose validation errors name the keys it is given; log messages `cooler: site cache purged` and `cooler: site cache purge failed` (attributes kind, slug, status, purged; never the token or the full URL); PurgeSiteCacheAfterCommit(ctx, db, p, kind, slug) unchanged (nil purger or nil db does nothing); `SiteCacheFromApp(app *backpack.App) *SiteCachePurger` returns a published purger, else builds one from the framework keys and publishes it (both keys empty or an invalid config returns nil; an invalid config logs one error naming the key). No debounce: one POST per committed save. cooler.go Install: unless a *SiteCachePurger is already published (a plugin's alias), build it from the framework keys; an invalid config is a boot error; a non-nil purger is published and one info line names its Endpoint. cooler imports neither surf nor cabana. Port the Journal tests to modules/cooler/sitecache_test.go as TestSiteCachePurgeConfig and TestSiteCachePurgeRequest with the framework keys and the cooler log messages. Docs: docs/services/caching.md section "Site cache purge" (both keys with SUMMER_ variables, loopback-only http, token length, after-commit timing, failures never fail a save, the Nuxt side: POST /api/__site__/cache/purge with NUXT_SITE_CACHE_PURGE_TOKEN and its cache:false route rule, a plugin hook example using cabana.TxFromContext and SiteCacheFromApp under a neutral plugin name); cooler README Features, API reference and Configuration rows; the cooler summary sentence in its README and the root README row both gain "and the site-cache purge after admin saves".
+
+FAQ plugin (one sm-faq-plugin commit), per D-11: controllers/site_cache.go adds `purgeSiteCache(ctx context.Context, app func() *backpack.App, kind, slug string)` taking the transaction from cabana.TxFromContext and the purger from cooler.SiteCacheFromApp, doing nothing when either is missing. faqs.go: FormAfterCreate and FormAfterUpdate run requireLocale first and purge kind faq with the FAQ's slug only when it passed; a new FormAfterDelete purges kind faq; add the pact.FormAfterDelete compile-time assert. README: a "Site cache" paragraph naming the framework keys. site_cache_admin_test.go `TestFaqAdminPurgesSiteCache` (Postgres through the existing TestMain; an httptest receiver set through cfg.Set of the two framework keys with a 32-character token): create, update and delete each send exactly one POST with Bearer token and kind faq after the commit; a create refused by the locale check sends none; a receiver answering 500 leaves the save successful.
+
+vue-faq-layer (one commit), per D-11: server/lib/siteCachePurge.ts ports authorize, purge and parse from the Journal util under the names MIN_SITE_PURGE_TOKEN_LENGTH, SITE_ROUTE_CACHE_BASE, authorizeSitePurge, purgeSiteRouteCache and parseSitePurgeEvent (kind accepted when it matches lower-case letters and underscores up to 40 characters, else unknown; slug sanitised as in the Journal util). server/api/__site__/cache/purge.post.ts mirrors the Journal route: no-store header, runtimeConfig siteCache.purgeToken, 404 when disabled or proxied, 401 unauthorized, answer {purged}, log prefix [site-cache]; it imports the lib by relative path and names no layer. nuxt.config.ts gains runtimeConfig siteCache.purgeToken '' (comment naming NUXT_SITE_CACHE_PURGE_TOKEN and the 32-character minimum) and routeRules '/api/__site__/**': { cache: false } with the Journal layer's explanatory comment. tests/sitePurge.test.ts (names start with "sitePurge:"): authorize ok and unauthorized with a 32-character token, purge removes only nitro:routes: keys from a fake storage, and a hash pin: sha256 of server/lib/siteCachePurge.ts and of the route file equal the constants SHARED_LIB_SHA256 and SHARED_ROUTE_SHA256 (write the files, compute the hashes, then write the constants; Tasks 2 and 3 copy the files and these constants byte for byte).

The deployment keeps its golem15.journal.site_cache.* and NUXT_JOURNAL_CACHE_PURGE_TOKEN values: the alias path makes menu and FAQ saves purge through the old Journal route, so no server config changes now; record moving the deployment to site_cache.* and NUXT_SITE_CACHE_PURGE_TOKEN as a follow-up. Nothing is pushed here (plan 05's release decision covers the app and vue app pushes).</action>

+
+| Boundary | Description |
+|----------|-------------|
+| Go app to the Nitro server | a bearer-token POST over loopback (or https) after admin saves |
+| network to the Nitro purge route | anyone who can reach the site can call the route |
+| plugin hooks to the save transaction | hook errors roll back admin writes |

+## STRIDE Threat Register

+|-----------|----------|-----------|----------|-------------|-----------------|
+| T-19.3-23 | Denial of service / Spoofing | the shared Nitro purge route | medium | mitigate | 404 below a 32-character token and for proxied requests (X-Forwarded-For, X-Real-IP, Forwarded), sha256 plus timingSafeEqual bearer compare, cache:false route rule in every layer; sitePurge specs |
+| T-19.3-24 | Information disclosure | purge token in Go logs and errors | high | mitigate | validation errors name keys only; log lines carry kind, slug, status and endpoint host and path, never the token or query; ported TestSiteCachePurgeRequest asserts it |
+| T-19.3-25 | Information disclosure | token sent in clear over the network | high | mitigate | http purge URLs must point at a loopback host, other hosts require https; user info refused |
+| T-19.3-26 | Denial of service | a slow or failing purge breaking admin saves | medium | mitigate | after-commit only (lagoon.AfterCommit), detached context with a 2 s timeout, failures logged and swallowed; the plugin tests assert a 500 receiver leaves saves successful |
+| T-19.3-27 | Tampering | purge before commit letting a page re-cache stale content | low | mitigate | PurgeSiteCacheAfterCommit registers on the save transaction; the FAQ and menu tests check the purge arrives after the commit |
+| T-19.3-28 | Tampering | a ReorderAfterSave hook failing | low | accept | the hook runs inside the reorder transaction by design so its failure rolls the reorder back, as FormAfter hooks do; purge hooks never return errors |
+| T-19.3-29 | Tampering | the three copies of the shared route drifting apart | low | mitigate | byte-identical files checked with cmp in Tasks 2 and 3 and a pinned sha256 in each layer's spec |
+| T-19.3-SC | Tampering | npm/pip/cargo or Go module installs | high | mitigate | no new packages: the layers reuse node:crypto and Nitro, the plugins use framework modules only; the app's go mod tidy only records modules the framework already pinned (decision note of plan 01) |

+# Phase 19.3 Plan 04: Framework site-cache purge Summary
+
+**The site-cache purge moved from the Journal plugin into cooler (keys `site_cache.purge_url` and `site_cache.purge_token`). Cabana gained a `pact.ReorderAfterSave` hook. FAQ, menu and Journal admin saves, deletes and reorders now purge the page cache after commit, through a shared `POST /api/__site__/cache/purge` route that ships in all three Nuxt layers. The plugins and layers are pushed and tagged, and the app's pointers are bumped locally.**
+
+## Performance
+
+- **Duration:** about 60 min (2026-10-15T16:16:40Z to 17:16Z, across two executor runs split at the Task 4 checkpoint)
+- **Tasks:** 5 of 5
+- **Files modified:** 14 framework, 4 FAQ, 6 menu, 6 Journal, 6 per layer, 7 app (incl. submodule pointers), 2 vue app
+
+## Accomplishments
+
+- `cooler.SiteCachePurger` is now a framework service. It is validated and published at boot, so a bad `site_cache` config fails boot. `SiteCacheFromApp` gives commands and tests the same purger lazily. `PurgeSiteCacheAfterCommit` sends one bearer POST of `{kind, slug}` per committed save.
+- `pact.ReorderAfterSave` is called inside cabana's reorder transaction after the new order is written. A hook error rolls the reorder back. Controllers without the hook behave as before.
+- FAQ create, update and delete purge, and so do menu create, update and delete and menu-entry create, update, delete and reorder. The existing locale and placement checks still run first.
+- Journal moved onto cooler. Its old keys and exported names still work as aliases, with a deprecation warning.
+- The shared Nitro route and helper are byte-identical in all three layers, pinned by sha256 in each layer's spec. Each layer has its own `'/api/__site__/**': { cache: false }` rule. vue-journal-layer keeps `/api/__journal__/cache/purge` and `journal.cachePurgeToken` as aliases.
+- The plugins, layers and summercms master are pushed, and the layer tags are on origin. sm-grzybyfunkcjonalne-app now runs the adopted plugins and layer versions. Its deployment config is unchanged because the Journal alias path keeps it working.
+
+## Task Commits
+
+| Task | Name | Repository: commit |
+|------|------|--------------------|
+| 1 (tracer) | FAQ save purges the site cache through cooler and the shared Nuxt route | summercms.go 0bc390f, sm-faq-plugin c60ae6e, vue-faq-layer e26f22e |
+| 2 | pact.ReorderAfterSave hook; menu plugin purges; vue-menu-layer route | summercms.go af9dad6, sm-menu-plugin 559d96b, vue-menu-layer 3bc7729 |
+| 3 | Journal moves onto cooler with alias keys; vue-journal-layer route | sm-journal-plugin d7943fb, vue-journal-layer 3e0b377 |
+| 4 | Push decision (checkpoint:decision, blocking-human) | pushes and tags below, no commits |
+| 5 | App picks up the purge | sm-grzybyfunkcjonalne-app f9cafe2 (go mod tidy), d604509 (journal/menu/faq pointers), 85939c3 (vue app pointer), 129c0df (DEPLOY.md, deviation); vue-grzybyfunkcjonalne-app 0ee97d0 (layer tags) |
+
+Framework commits measured from the ledger: `git rev-list --count 1d8e50a..HEAD` = 2.
+
+## Task 4: push decision
+
+**Reply (verbatim):** push-all
+
+Before pushing, I re-ran `git fetch origin --tags` in all seven repositories. None was behind origin. `git ls-remote --tags origin` showed no v0.2.0 on vue-faq-layer or vue-menu-layer and no v0.4.0 on vue-journal-layer, and none of these tags existed locally. The previous run had already printed push-gate-ok (all plugin and layer suites green, Docker tests run).
+
+Pushed (no force, no framework tag):
+
+| Repository | Branch | Range pushed |
+|------------|--------|--------------|
+| summercms.go | master | a9dd565..af9dad6 (also carries plans 19.3-01, -02 and -03 and the phase planning commits) |
+| sm-faq-plugin | main | 919cf06..c60ae6e |
+| sm-menu-plugin | main | 9c0f833..559d96b |
+| sm-journal-plugin | main | 31d901c..d7943fb |
+| vue-faq-layer | main | 321bc90..e26f22e |
+| vue-menu-layer | main | 2deac88..3bc7729 |
+| vue-journal-layer | main | 25e9bfe..3e0b377 |
+
+Annotated tags created and pushed:
+
+| Repository | Tag | Tag object | Commit |
+|------------|-----|------------|--------|
+| vue-faq-layer | v0.2.0 | 8acbde2 | e26f22e |
+| vue-menu-layer | v0.2.0 | a6942aa | 3bc7729 |
+| vue-journal-layer | v0.4.0 | 9213af5 | 3e0b377 |
+
+Checked after the push: each plugin's `main` equals `origin/main`, summercms `master` equals `origin/master`, and `ls-remote` prints each tag. The latest framework tag on origin is still v0.1.9 in the tag listing; no new framework tag was made.
+
+**Not pushed:** sm-grzybyfunkcjonalne-app (4 commits) and vue-grzybyfunkcjonalne-app (1 commit) stay local. Plan 05's release decision covers those pushes. Nothing was deployed.
+
+## Identifiers and keys added
+
+- **cooler:** `SiteCachePurger`, `NewSiteCachePurger`, `NewSiteCachePurgerFor`, `SiteCachePurger.Purge`, `SiteCachePurger.Endpoint`, `PurgeSiteCacheAfterCommit`, `SiteCacheFromApp`, `SiteCachePurgeURLKey`, `SiteCachePurgeTokenKey`, `SiteCachePurgeTimeout`, `SiteCachePurgeMinTokenLength`
+- **pact:** `ReorderAfterSave`
+- **Config keys:** `site_cache.purge_url` (SUMMER_SITE_CACHE__PURGE_URL), `site_cache.purge_token` (SUMMER_SITE_CACHE__PURGE_TOKEN)
+- **Layers:** runtimeConfig `siteCache.purgeToken` (NUXT_SITE_CACHE_PURGE_TOKEN); route `POST /api/__site__/cache/purge`; `server/lib/siteCachePurge.ts` exports `MIN_SITE_PURGE_TOKEN_LENGTH`, `SITE_ROUTE_CACHE_BASE`, `authorizeSitePurge`, `purgeSiteRouteCache`, `parseSitePurgeEvent`
+- **Purge kinds:** `faq`, `menu`, `menu_entry` (slug `partition:<id>` on reorder), Journal `post` and `category`
+
+**Shared-file sha256 pins (identical in all three layers):**
+- `server/lib/siteCachePurge.ts`: `7c34121ae06cf011b30a1dc5d787a94657b71b8768bed3a200be0f41566001b8`
+- `server/api/__site__/cache/purge.post.ts`: `c459012280cdf59551e57f0440fcaeb24566a5ba6e3dccf31133e67a683f1c06`
+
+## Tests
+
+- Docker-backed tests **ran** (not skipped): `TestFaqAdminPurgesSiteCache`, `TestMenuAdminPurgesSiteCache` and the Journal admin purge test on Postgres. All suites were green.
+- Extra tests: `TestSiteCacheFrameworkKeysWin` (Journal) and `TestSiteCachePurgeConfig` subtests in cooler.
+- Task 5: the app passed `go build ./...` and `go test -short ./...`. In the vue app, `pnpm run build` succeeded, `pnpm test` passed 27/27 and `smoke:ssr` passed 38 checks. The built Nitro config carries `"/api/__site__/**": { "cache": false }` and the `/api/__site__/cache/purge` handler. The Task 5 automated verify printed TASK5-VERIFY-OK, and `grep -c '#v0.2.0'` returned 2.
+
+## Decisions Made
+
+See key-decisions in the frontmatter. Task 4 reply: push-all.
+
+## Deviations from Plan
+
+### Auto-fixed Issues
+
+**1. [Rule 3 - Blocking] cabana reorder runs in lagoon.Transaction**
+- **Found during:** Task 2
+- **Issue:** `reorderPost` in `modules/cabana/reorder.go` used a plain GORM Transaction, so `lagoon.AfterCommit` skipped and a purge registered from `ReorderAfterSave` would never be sent.
+- **Fix:** It now runs in `lagoon.Transaction`. The existing reorder tests pass.
+- **Commit:** summercms.go af9dad6
+
+**2. [Docs checker] cooler example and configuration row**
+- **Found during:** Task 1
+- **Issue:** The docs checker needed real snippets for caching.md.
+- **Fix:** `modules/cooler/example_test.go` gained `ExampleSiteCacheFromApp` and a neutral `articlesController`, and caching.md pulls them via `src=`. A `docs/setup/configuration.md` row was added for the new keys, which was not in files_modified.
+- **Commit:** summercms.go 0bc390f
+
+**3. [Commit order] af9dad6 amended after the menu plugin commit**
+- **Found during:** Task 2
+- **Issue:** The acceptance grep wants exactly one `pact.ReorderAfterSave` line in reorder.go, but one comment repeated the name.
+- **Fix:** The comment was reworded and af9dad6 amended. This happened before any push.
+
+**4. [Rule 2 - Docs correctness] sm-grzybyfunkcjonalne-app DEPLOY.md**
+- **Found during:** Task 5
+- **Issue:** After the pointer bump, DEPLOY.md still said menu and FAQ edits do not purge the cache. It also named the old `journal: site cache purged` log line, which is now `cooler: site cache purged`.
+- **Fix:** Three sentences were updated: which saves purge, the cooler log lines, and the boot-time deprecation warning for the journal keys, which keep working. `scripts/check-deploy.sh` passes.
+- **Files modified:** ../sm-grzybyfunkcjonalne-app/DEPLOY.md
+- **Commit:** sm-grzybyfunkcjonalne-app 129c0df (separate docs commit after the pointer bumps)
+
+**5. [Rule 3 - Blocking] pnpm install without a TTY**
+- **Found during:** Task 5
+- **Issue:** `pnpm install` aborted with ERR_PNPM_ABORTED_REMOVE_MODULES_DIR_NO_TTY.
+- **Fix:** It was re-run with `--config.confirmModulesPurge=false`, which rebuilds the local node_modules only. The lockfile diff touches only the three layer entries.
+
+## Issues Encountered
+
+None beyond the deviations. Pre-existing untracked files were left alone: sm-grzybyfunkcjonalne-app `.gsd/` and its nested `sm-grzybyfunkcjonalne-app` entry, and sm-journal-plugin `go.work.sum`.
+
+## Deferred Items
+
+Logged in `deferred-items.md`:
+- Pre-existing gofmt findings (missing trailing newlines) in `modules/cabana/account_tokens.go`, `account_tokens_test.go`, `token_postgres_smoke_test.go`, `token_routes_test.go`, `token_scopes_test.go` and sm-journal-plugin `classes/blog_editor_test.go`.
+
+## Follow-ups
+
+- Move the grzybyfunkcjonalne deployment to `site_cache.purge_url`/`site_cache.purge_token` and `NUXT_SITE_CACHE_PURGE_TOKEN` (route `/api/__site__/cache/purge`) before the Journal alias keys are removed. Until then the binary logs a deprecation warning at boot.
+- Bump the Journal pointer in sm-summercmsio-app, which is 45 commits behind main.
+- Push sm-grzybyfunkcjonalne-app (f9cafe2, d604509, 85939c3, 129c0df) and vue-grzybyfunkcjonalne-app (0ee97d0) under plan 05's release decision.
+- Manual check from 19.3-VALIDATION.md: save a menu entry in a running admin and see the page update without waiting for the SWR window.
+
+## Next Phase Readiness
+
+Plan 05 (unit tests and the framework release decision) can start. summercms master on origin already carries the cooler purge service that the pushed plugins import.
+
+## Self-Check: PASSED

+## Phase Goal
+
+ROADMAP Goal (not in user-story format; no story is invented, see plan 01): the framework has the transport and infrastructure pieces a multi-client, multi-instance application needs: JWT cookie refresh across subdomains, credentialed CORS, a cache module with a Redis-backed rate-limit store, an S3 blob option, an OpenAPI page and Turnstile verification.
+
+This plan's slice (plan 5 of 5, wave 3): SC-4's unit tests, delivered last as CLAUDE.md requires, behind a fail-closed phase gate script, then the phase's release decision.
+
+## Spec-less probe fallback
+
+Skipped visibly: the phase has no requirement IDs to probe, so no probe predicates were generated (see plan 01).
+
+## Decisions taken in this plan (Claude's discretion)
+
+- The gate follows scripts/check-phase18.1.sh: named required tests per stage, `go test -v` output checked for a `--- PASS` line per name, a skip or a missing name fails the stage, `--all` reports Docker stages as NOT RUN without a daemon (an env var makes that fail instead).
+- Smoke tests from plans 01 to 04 stay; this plan adds the unit files next to them and extends the plan-01 store lookup file and the plan-04 purger test file instead of duplicating them.
+- Rate-limit parity runs one table of (key, max, decay, advance) steps through a small adapter: for MemoryStore the test waits on real time with short decays; for miniredis it calls FastForward; for Docker Redis it waits. The table includes window expiry, denial without increment and retryAfter never growing.
+- The release proposal is the highest `v0.1.*` tag plus one (v0.1.27 at planning time), pushed only on the human's reply, after which the three plugins' go.mod require that tag.
+
+## Artifacts this phase produces (this plan)
+
+- `scripts/check-phase19.3.sh` with stages `go`, `docker`, `plugins`, `layers`, `docs` and `--all`.
+- Test files: `modules/bouncer/cookie_test.go`, `modules/bouncer/turnstile_test.go`, `modules/surf/cors_profile_test.go`, `modules/surf/apidocs_test.go`, additions in `modules/surf/store_lookup_test.go`, `modules/cabana/reorder_hook_test.go`, `internal/build/manifest_tags_test.go`, `modules/lagoon/attach/s3_test.go`, `modules/lagoon/attach/diskext_test.go`, additions in `modules/lagoon/attach/store_test.go` and `url_test.go`, `modules/cooler/memory_test.go`, `redis_test.go`, `ratelimit_test.go`, `docker_test.go`, `install_test.go`, additions in `sitecache_test.go`, `../sm-journal-plugin/site_cache_keys_test.go`, `../sm-faq-plugin/controllers/site_cache_test.go`, `../sm-menu-plugin/controllers/site_cache_test.go`, extended `tests/sitePurge.test.ts` in the three layers.
+- Test dependency `github.com/alicebob/miniredis/v2` v2.40.0 (after the human check).
+- 19.3-VALIDATION.md per-task map filled and `wave_0_complete: true`.
+- Release: proposed framework tag, plugin go.mod bumps to it, pushes, all on the human's reply.
+
+<objective>
+Deliver the unit tests for all new code of the phase, a fail-closed phase gate that runs them by name, and the release decision.
+
+Purpose: SC-4 ("the new code has unit tests, delivered in the phase's last plan") and the test rows of 19.3-VALIDATION.md for every decision.
+Output: test files in summercms.go, the three plugins and the three layers; the gate script; the release record.

+
+Rules: tests only; a production fix is allowed only for a defect a new test exposes, committed separately as `fix(19.3): …` and recorded as a deviation. Commit per repository, staging by explicit path, no co-author tags. Before each task run `git status --porcelain` on the paths it touches and stop on foreign uncommitted edits (Phase 18.1 work may be in flight in cabana). Docker suites skip under `-short`; run them on a Docker host (`sudo -u golem` when the socket is denied) and record NOT RUN when no daemon answers. Nothing is pushed or tagged before the Task 7 reply.

+# Phase 19.3 Plan 05: unit tests, phase gate and release Summary
+
+**Fail-closed gate `scripts/check-phase19.3.sh` requires every new 19.3 test by name across the framework, three plugins and three Nuxt layers. It passed on all six stages, Docker included. The phase is released as summercms v0.1.27, and the FAQ, menu and Journal plugins now require that tag on origin.**
+
+## Checkpoint replies
+
+### Task 4 (miniredis legitimacy check)
+
+The reply below was recorded verbatim (commit b139651) before any go.mod change in Task 5:
+
+> approved
+
+The orchestrator sent this instruction with it: install github.com/alicebob/miniredis/v2@v2.40.0 as a test-only dependency, so only `_test.go` files in modules/cooler may import it. Checked after Task 5: `grep -n 'github.com/alicebob/miniredis/v2 v2.40.0' go.mod` prints line 10, and `grep -rl 'alicebob/miniredis' --include='*.go' modules | grep -vc '_test.go$'` prints 0.
+
+### Task 7 (release decision)
+
+The reply below is recorded verbatim:
+
+> release
+
+The orchestrator scoped it to exactly the "release" option:
+
+1. Tag v0.1.27 and push master and the tag.
+2. Bump the three plugins, test them and push them.
+3. Push the layer test commits, with no new layer tags.
+4. Push the plan 04 app commits, vue app first.
+
+It also set these rules: never force-push, run fetch and a divergence check before each push, deploy nothing, and leave the app's plugin submodule pointer bump out of scope.
+
+## Release record
+
+- **Tag:** `v0.1.27` is an annotated tag (object d0e39437) on summercms.go master 9921768. `git ls-remote --tags origin refs/tags/v0.1.27` prints `d0e39437b5b56ba77b82267693de189bf5d1329d` and peels to `9921768bbf0814671a89eafd45f949afcc113a11`.
+- **Preflight before each push:**
+  - `git fetch origin --tags` ran in every repository, and nothing was behind origin.
+  - v0.1.27 was free on origin before tagging, and `go vet ./... && go build ./...` passed on 9921768.
+  - The only change since the green `--all` gate run is planning docs.
+- **summercms.go:** pushed master `af9dad6..9921768`. This covers plan 04's 6f9f2e2 and 6035ccc and this plan's 619916b through 9921768. Then the tag was pushed. `git rev-parse master` equals `git rev-parse origin/master`. The final SUMMARY and state commit lands after the tag and is pushed plainly to master.
+- **Plugins:**
+  - Each one ran `GOWORK=off go get git.golem15.com/golem15/summercms@v0.1.27` and `GOWORK=off go mod tidy`.
+  - The tidy added go-redis v9.23.0, otter v2.3.0, google/wire and the AWS SDK v2 modules as indirect requires.
+  - `GOWORK=off go vet ./...` and `GOWORK=off go test -count=1 ./...` passed in all three, Docker suites included. `go test -short ./...` also passed through the workspace.
+  - Pushed main:
+    - sm-faq-plugin `c60ae6e..fa90e83` (e117bb4, then fa90e83 "chore(19.3-05): require summercms v0.1.27").
+    - sm-menu-plugin `559d96b..fe27b9a` (6c08f1a, fe27b9a).
+    - sm-journal-plugin `d7943fb..a99e9a1` (ebfb710, a99e9a1).
+  - `grep -n "git.golem15.com/golem15/summercms v0.1.27"` prints one line per go.mod: faq line 7, menu line 6, journal line 8.
+- **Layers (test commits only, no new tags):**
+  - vue-faq-layer `e26f22e..96b6bc0`
+  - vue-menu-layer `3bc7729..dd0ee35`
+  - vue-journal-layer `3e0b377..5936f66`
+- **App, vue app first:**
+  - vue-grzybyfunkcjonalne-app `bc143fa..0ee97d0`.
+  - Then sm-grzybyfunkcjonalne-app `4bab6f1..129c0df` (f9cafe2, d604509, 85939c3, 129c0df).
+- **No force-push, no deploy.**
+
+## Performance
+
+- **Started:** 2026-10-15T17:19:19Z, across three executor runs with checkpoints at Task 4 and Task 7.
+- **Completed:** 2026-10-15T18:08Z
+- **Tasks:** 7 of 7
+- **Framework commits since the plan ledger:** 9 (6035ccc..9921768), measured when this SUMMARY was written. The completion commit follows.
+- **Commits in other repositories:** 9 in all. Six are test commits (Task 6) and three are plugin go.mod bumps (Task 7).
+
+## Accomplishments
+
+- The gate has stages `--self-test`, `go`, `docker`, `plugins`, `layers` and `docs`, plus `--all`.
+  - A stage fails when a required test is missing, skipped or red.
+  - When no Docker daemon answers, `--all` reports docker as NOT RUN. It fails instead when PHASE193_REQUIRE_DOCKER=1.
+- The cooler suites cover:
+  - the memory and Redis caches;
+  - the rate-limit parity table, run through surf.MemoryStore, miniredis and real Redis;
+  - concurrency, the fallback on a Redis error and the key prefixes;
+  - Install and FromApp;
+  - the site-cache purge on Postgres: rollback, commit, nested transactions, a 500 answer, a slow receiver and an unreachable one.
+- In the plugins: tests for the FAQ and menu `purgeSiteCache` helpers, and for the Journal's deprecated keys (framework keys win; alias keys are deprecated or invalid; no keys).
+- In the layers: the shared purge spec grows from 6 to 11 tests and is byte-identical in all three layers. The new tests cover:
+  - route-handler specs for 404, 401 and 200;
+  - the purge count and the log line;
+  - timing-safe comparison across bearer lengths;
+  - parse edge cases.
+- Release: v0.1.27 is published. The three plugins on origin build against it without a sibling checkout.

+
+## Test names per repository (all required by the gate)
+
+- **summercms.go, go stage (-short):**
+  - bouncer: 17 names (TestLoadCookieConfigDefaults … TestTurnstileNeverLogsSecret).
+  - surf: 23 names (TestCORSCredentialsWildcardRefused … TestBuildRouterNeverDials, including TestCORSOptionsMatchesLaravel).
+  - internal/build: 4 names.
+  - attach: 4 names, run twice (untagged and with `-tags summercms_s3`).
+  - cooler: TestMemoryCache, TestMemoryCacheTTL, TestMemoryCacheBounded, TestMemoryIncrementConcurrent, TestRememberDegrades, TestRedisCache, TestRedisFlushOnlyPrefix, TestRateLimitParity, TestRateLimitConcurrentNeverExceedsMax, TestRateLimitFallbackOnError, TestRateLimitKeyPrefix, TestInstallConfigErrors, TestInstallPingWarning, TestInstallReusesFromApp, TestFromAppLazy, TestInstallSiteCacheValidation, TestSiteCachePurgeConfig, TestSiteCachePurgeRequest, TestSiteCacheFromApp.
+- **summercms.go, docker stage:**
+  - cabana: TestReorderHookRunsInTx, TestReorderHookErrorRollsBack, TestReorderWithoutHookUnchanged.
+  - attach: TestStoreDiskExtension.
+  - cooler: TestRateLimitParityDocker, TestRedisCacheDocker, TestSiteCacheAfterCommitOnly, TestSiteCacheFailureNeverFails.
+- **Plugins, plugins stage:**
+  - FAQ and menu `./controllers`: TestPurgeSiteCacheWithoutTx, TestPurgeSiteCacheWithoutPurger.
+  - Journal: TestSiteCacheFrameworkKeysWin, TestSiteCacheAliasKeysDeprecated, TestSiteCacheNoKeys; `./classes`: TestSiteCachePurgeConfig, TestSiteCachePurgeRequest.
+- **Plugins, docker stage:** TestFaqAdminPurgesSiteCache, TestMenuAdminPurgesSiteCache, TestCategoriesAdminPurgesSiteCache, TestPostsAdminPurgesSiteCache, TestCategoriesAdminFrameworkKeysWin.
+- **Layers, layers stage:** 11 `sitePurge:` names per layer, plus a `cmp` of server/lib/siteCachePurge.ts, server/api/__site__/cache/purge.post.ts and tests/sitePurge.test.ts across the three layers.
+
+## Gate runs
+
+All runs were on 2026-10-15 on a Docker host:
+
+- `bash scripts/check-phase19.3.sh --all` passed self-test, go, plugins, layers, docs and docker, ending with "Phase 19.3 gate passed". The docker stage actually ran; it was not NOT RUN.
+- `go test -count=1 -run '^TestDocsTree$' ./cmd/summer` and `(cd examples/hello && go test ./...)` both passed, giving release-gate-ok.
+- A full `go test -count=1 ./...` with all Docker suites exited 0: 41 packages ok and no FAIL lines.
+- Before tagging, `go vet ./... && go build ./...` passed on 9921768.
+- After the bump, each plugin passed `GOWORK=off go vet ./...` and `GOWORK=off go test -count=1 ./...`, Docker included.
+- Fail-closed checks (every planted break was reverted and never committed):
+  - Task 1: renaming TestForgetTokenCookie made the go stage exit 1, and `nosuchstage` exits 2 with a usage line.
+  - Task 6: a planted consuming-application name in modules/cooler/redis.go made `docs` exit 1, and a one-line drift in vue-menu-layer's spec made `layers` exit 1.
+
+## Decisions Made
+
+- The gate reuses check-phase18.1.sh's `go test -json` detector. A skip, a missing name, no tests, zero tests or a build failure all fail the stage.
+- Each cooler Docker test starts its own container instead of sharing one through a TestMain: Postgres for the purge tests, redis:7-alpine for the rest. Nothing starts before flag parsing, and each test skips itself under `-short`.
+- The docs stage scans the lines the phase added (`git diff <first 19.3 commit>^`, with `.planning` excluded) for consuming-application names. The names are split in the script so the scan does not match itself, and PHASE193_BASE overrides the base.
+- TestStoreDiskExtension, row "js under octet-stream": the test expects content_type text/javascript and the disk name `.bin`. The content type comes from the extension because the sniff is generic (the plan 03 rule); the disk name follows D-15.
+- Release (Task 7, reply "release"): v0.1.27 is an annotated tag on master. The plugin bump commits use the subject `chore(19.3-05): require summercms v0.1.27`. The app's plugin submodule pointers stay where they are (out of scope; see Follow-ups).
+
+## Deviations from Plan
+
+### Auto-fixed Issues
+
+**1. [Rule 3 - Blocking] Task 3 verify grep could never match**
+- **Found during:** Task 3
+- **Issue:** `grep -q -- '^--- PASS: TestOpenBucketS3$'` cannot match, because `go test -v` appends the duration to the line.
+- **Fix:** checked with `grep -qE '^--- PASS: <name>( |$)'` instead (T3-VERIFY-OK). The gate itself uses the JSON detector.
+- **Commit:** 38f6d65
+
+**2. [Rule 3 - Blocking] Duplicate test name in the Journal test binary**
+- **Found during:** Task 6
+- **Issue:** plan 04 had added a Docker test named `TestSiteCacheFrameworkKeysWin` in package journal_test, and this plan gives the same name to the new unit test in package journal. `-run '^TestSiteCacheFrameworkKeysWin$'` matched both. Under `-short` the Docker one skipped, and the gate's skip detector failed the stage.
+- **Fix:** renamed the Docker test to `TestCategoriesAdminFrameworkKeysWin` (it saves a category with both key sets) and required it in the docker stage. The unit test keeps the plan's name.
+- **Files modified:** ../sm-journal-plugin/site_cache_admin_test.go
+- **Commit:** ebfb710
+
+**3. [Discretion] Branch the plugin helper unit tests cannot reach**
+- `TestPurgeSiteCacheWithoutPurger` covers a nil app, a nil app result and an app without keys.
+- No unit test can reach the branch "inside a transaction, no purger". cabana has no exported constructor for a context carrying a transaction, and this plan allows no production changes.
+- The plugins' Docker admin suites reach that branch. The gap is logged in deferred-items.md.
+
+No production code changed in this plan.
+
+## Issues Encountered
+
+- On each failing call against a stopped Redis, go-redis logs `failed to dial after 5 attempts` to stderr. With Redis down, `Cache.Remember` waits about 1.7 s for those retries unless the caller's context has a deadline. Logged in deferred-items.md as a follow-up.
+- The earlier follow-up, a committed test for the rate-limit store's fallback during a Redis outage, is now TestRateLimitFallbackOnError. Each attempt answers from the fallback within about AttemptTimeout and logs one warning naming the endpoint.
+- Earlier finding (df7db6c), unchanged: S3 object metadata carries the sniffed content type. An HTML body uploaded as note.txt is stored with Content-Type text/html.
+
+## Follow-ups
+
+- **Not done, outside the release reply's scope:** sm-grzybyfunkcjonalne-app still points its plugin submodules at the plan 04 commits: plugins/golem15/faq c60ae6e, journal d7943fb and menu 559d96b. Bumping them to fa90e83, a99e9a1 and fe27b9a (the v0.1.27 go.mod commits) is a separate app commit. It needs its own go-ahead, and then a push.
+- Apps that build against ../summercms.go need `go mod tidy` once for go-redis, otter and the AWS SDK modules. sm-grzybyfunkcjonalne-app already has it (f9cafe2).
+- Nothing was deployed. Manual UAT for /msd-verify-work 19.3 is still open: subdomain cookies, a real S3 bucket and a live purge.
+- Left untouched in the working trees, as instructed: sm-journal-plugin/go.work.sum, sm-grzybyfunkcjonalne-app/.gsd/, and an untracked `sm-grzybyfunkcjonalne-app/sm-grzybyfunkcjonalne-app` entry inside the app checkout. It is not from this plan.
+
+## Known Stubs
+
+None.
+
+## Next Phase Readiness
+
+Plan 05 is the last plan of phase 19.3, so the phase is complete. The next steps are /msd-verify-work 19.3 for manual UAT and the app's plugin pointer bump listed above.
+
+## Self-Check: PASSED
+
+- All 17 created test and gate files exist.
+- All 20 listed commits are reachable from origin in their repositories: summercms.go, three plugins, three layers, the vue app and the app.
+- `refs/tags/v0.1.27` on origin is d0e3943, which peels to 9921768.

+## Phase Goal
+
+ROADMAP Goal (not a user story; standard goal-backward planning, as in plans 01 to 05): the framework has the transport and infrastructure pieces a multi-client, multi-instance application needs: JWT cookie refresh across subdomains, credentialed CORS, a cache module with a Redis-backed rate-limit store, an S3 blob option, an OpenAPI page and Turnstile verification.
+
+This plan's slice (plan 6, gap closure, wave 4): close the one verification gap (CR-01: `cors:<profile>` headers missing from refusals, 413 and 500, which hides the 401 the SPA needs for its cookie refresh) and fix the nine review warnings WR-01..WR-09 of 19.3-REVIEW.md, then release v0.1.28 on the human's reply.
+
+## Gap being closed (19.3-VERIFICATION.md `gaps[0].missing`)
+
+| Missing item | Task |
+|--------------|------|
+| `Router.wrap` skips the `cors:<profile>` entry and applies `r.corsProfiles[profile].profileMiddleware` after recovery, just inside `recordPattern` | Task 1 |
+| Test: guard listed before `cors:spa` → 401 with ACAO, ACAC, `Vary: Origin`; same for a body-limit 413 and a recovered 500; in SURF_TESTS | Task 1 (plus a group-level guard, a 403, a 429 and the Turnstile 422 and 503) |
+| docs/services/routing.md and modules/surf/README.md: the profile applies to every response regardless of position | Task 1 |
+
+Review warnings: WR-04, WR-05, WR-09 in Task 2; WR-06, WR-07, WR-08 in Task 3; WR-02, WR-01 in Task 4; WR-03 in Task 5. Unit-test breadth and gate wiring in Task 6; release in Task 7. IN-01..IN-11 are out of scope (user decision).
+
+## Decisions taken in this plan (user decisions of this gap run, then Claude's discretion)
+
+- One plan, not split (user). Each finding lands as its own commit with its README and docs lines, carrying one focused regression test; the unit-test tables and the gate wiring for Tasks 2 to 5 come in Task 6, the plan's last code task (project rule: unit tests last). Task 1 wires its own test into the gate because the verification gap names that step.
+- CR-01: besides moving the profile outermost, `bufferedResponse.commit` merges `Vary` instead of replacing it. Found while planning: once the profile sets headers on the outer writer, a handler that sets its own `Vary` would otherwise erase `Vary: Origin` on commit (the global `http.cors` wrapper has the same latent problem and benefits).
+- WR-04: three rules apply only with credentials: a wildcard is a whole leftmost host label, a pattern is anchored with `^` and `$`, and no origin pattern may match the probe origins `https://cors-probe.invalid`, `http://cors-probe.invalid`, `https://cors-probe.com` and `null`. Refusing (not auto-anchoring) keeps the matching semantics of existing non-credentialed configs. No app in the sibling repos uses credentialed CORS today.
+- WR-05: the review's primary fix (a boot error), not only a warning. WR-09: the zero `CookieConfig` gets Secure and SameSite=Lax; a partially filled config keeps its Secure value and gets Lax when SameSite is unset.
+- WR-06: the nonce goes on all three script tags and `script-src` keeps only the nonce. `default-src`/`connect-src`/`style-src` are not added, so Swagger UI "Try it out" against other servers keeps working; human UAT item 4 (render under CSP) remains.
+- WR-07: refuse (`attach.ErrProtectedNeedsPrivateBucket`) rather than only warn; `public_url` is new in v0.1.27 and no deployment sets it. cabana's upload handler answers the new error through its existing default branch (logged, opaque error); cabana is not changed.
+- WR-08: a warning at boot, not a boot error (turnstile:closed already answers 503 in production without a secret).
+- WR-01: in-flight coalescing on the purger (one request in flight, later saves collapse into one follow-up), no timer debounce. This supersedes plan 04's "one request per committed save, no debounce" by the user's decision in this gap run. `Purge` stays the synchronous send; `PurgeSiteCacheAfterCommit` queues. New exported `(*SiteCachePurger).Wait(ctx)` for tests, commands and shutdown. The plugin admin tests wait on it before asserting, which is why the plugins require the new framework tag at release.
+- WR-03: the review's second option (the route accepts proxied requests on an explicit opt-in, `siteCache.allowProxied`). The first option, restricting `site_cache.purge_url` to loopback, would refuse at boot an https purge URL that a Journal deployment may already carry through the alias keys, which breaks a core plugin. The default stays "refuse proxied". Layer versions are additive minors: vue-faq-layer 0.3.0, vue-menu-layer 0.3.0, vue-journal-layer 0.5.0, tagged only at Task 7.
+- Release: highest `v0.1.*` plus one (v0.1.28 at planning time). After the tag, the three plugins require it, as in plan 05. The app's layer pins and plugin pointers are a follow-up outside this plan.
+
+<assumption_delta_decision>
+Detector signal: `chosen` on "configurable" (SC-1 cookie attributes). Primary noun: the resolved token-cookie attributes (`bouncer.CookieConfig`). Decision: no-change. The attributes have been configurable since plan 02; this plan only tightens the derived Secure value in production (WR-05) and fills the zero-config defaults (WR-09).
+</assumption_delta_decision>
+
+## Context budget and resume point
+
+The plan stays one plan (user decision), so its estimate exceeds one executor context. It runs in at most two contexts, split after Task 4. Tasks 1-4 hold the six framework fixes and the three plugin repositories; Tasks 5-7 hold the layers, the unit-test tables, the full gate and the release.
+
+- **Record.** The last step of Task 4 writes `.planning/phases/19.3-framework-transport-and-infrastructure-for-wavepath/19.3-06-PROGRESS.md` and commits it as a planning-docs commit. The record is deliberately not a SUMMARY. execute-phase treats a plan that has a `-SUMMARY.md` as finished, so a partial SUMMARY would skip Tasks 5-7 and the release checkpoint.
+- **Resume rule.** Before Task 1, an executor of this plan checks for the record. When the record exists and `19.3-06-SUMMARY.md` does not, it does three things. It confirms every commit the record lists (`git -C <repo> cat-file -e <hash>`). It does not redo the tasks the record marks done. It starts at the task named on the record's `next:` line. A later task is skipped only when its commits exist (subject with `(19.3-06)` and the finding ID) and its acceptance criteria hold. A partly done task resumes at its first missing commit.
+- **After a reset.** If the executor's context ends after Task 4, execute-phase's resume gate finds plan-06 commits without a SUMMARY and asks how to recover. The fitting answer is a continuation executor: its completed tasks are the record's table and its resume point is the `next:` task. Re-executing from scratch would duplicate the plugin commits in the sibling repositories.
+- **Close-out.** The SUMMARY carries over the record's commits, verify results and notes. The record stays as written.
+
+## Artifacts this phase produces (this plan)
+
+- surf: `Router.wrap` applies `cors:<profile>` outermost (inside `recordPattern`); `bufferedResponse.commit` merges `Vary`; credentialed origin rules in `validateCORSConfig` (probe origins); api-docs page with a nonce on every script and a nonce-only `script-src`; boot warning `surf: turnstile.secret is empty` with a route count.
+- bouncer: `LoadCookieConfig` refuses an inferred insecure cookie in production; `CookieConfig` zero-value defaults (SameSite=Lax, Secure).
+- lagoon/attach: `attach.ErrProtectedNeedsPrivateBucket`; `attach.Store` refuses protected uploads while `storage.uploads.public_url` is set; the OpenBucket boot line becomes a warning.
+- cooler: purge client without redirects; queued, coalesced after-commit purges; `cooler.SiteCachePurger.Wait`; `Handle.Close` drains the purger.
+- Layers: `siteCache.allowProxied` (`NUXT_SITE_CACHE_ALLOW_PROXIED`) in the shared purge lib, route and nuxt.config, byte-identical in vue-faq-layer 0.3.0, vue-menu-layer 0.3.0 and vue-journal-layer 0.5.0, with two new `sitePurge:` specs and updated hash pins.
+- Plugin tests: FAQ, menu and Journal admin purge tests wait for the queued purge.
+- Tests: TestCORSProfileHeadersOnRefusals, TestCORSProfileVaryKeptWithHandlerVary, TestCORSCredentialedOriginRules, TestCORSAnchoredPatternNoSuffixMatch, TestAPIDocsCSPNoHostSource, TestTurnstileEmptySecretWarnsAtBoot, TestLoadCookieConfigProductionInferredSecure, TestZeroCookieConfigDefaults, TestStoreProtectedNeedsPrivateBucket, TestSiteCachePurgeNoRedirect, TestSiteCachePurgeAsyncCoalesced, TestSiteCachePurgeWaitAndClose, TestSiteCacheBulkCommitCoalesced (Docker); regression rows in TestCORSCredentialsWildcardRefused, TestLoadCookieConfigErrors, TestTokenCookieAttributes, TestAPIDocsServesPinnedPage.
+- Gate: every new name required in scripts/check-phase19.3.sh (go, docker and layers stages).
+- Docs: routing.md (CORS profiles, credentials rules, api-docs CSP), authentication.md (cookie Secure rule, zero config, Turnstile warning), storage.md (public_url refuses protected uploads), caching.md (queued purges, redirects, remote purge URL with allowProxied); surf, bouncer, lagoon and cooler READMEs; layer READMEs.
+- Planning: 19.3-REVIEW-DISPOSITION.md (CR-01, WR-01..WR-09 fixed), 19.3-VALIDATION.md rows for plan 06.
+- Release (on the human's reply): tag v0.1.28, plugin go.mod bumps, layer tags v0.3.0, v0.3.0 and v0.5.0.
+
+<objective>
+Close the CR-01 verification gap so a credentialed SPA can read every answer of a `cors:<profile>` route, fix review warnings WR-01..WR-09 with docs and tests, and release v0.1.28 on the human's reply.
+
+Purpose: SC-1/D-05 (the failed truth), the hardening behind D-03, D-04, D-10, D-11, D-12, D-17 and D-18, and SC-4 (docs and unit tests for the changed code).
+Output: commits in summercms.go, the three plugins (tests only) and the three layers; the updated gate; the disposition record; the release record.

+Rules: one commit per finding where practical, README and docs in the same commit as the code they describe, planning docs in separate commits; stage by explicit path, never `git add -A`; no co-author tags. Before each task run `git status --porcelain` on the paths it touches and stop on foreign uncommitted edits (other sessions work in this checkout; `.planning/state.json` and `.msd/` are theirs, leave them alone; sm-journal-plugin's untracked go.work.sum stays untouched). Framework commits land before the plugin and layer commits that depend on them. The plugins build against this checkout through their checked-in go.work. Docker suites skip under `-short`; run them on a Docker host (`sudo -u golem` when the socket is denied) and record NOT RUN when no daemon answers. Framework code and docs never name a consuming application (the gate's docs stage scans added lines). Nothing is pushed or tagged before the Task 7 reply. State updates go through `msd_run query state.*` handlers. Before Task 1, apply the resume rule in "Context budget and resume point" (19.3-06-PROGRESS.md).

+  <action>Per D-05 (CR-01, the verification gap). router.go wrap: before the middleware loop, resolve the route's profile with routeCORSProfile(rt) (return its error as is) and keep today's unknown-profile boot error with its message. Inside the loop, an entry whose base is cors (with a param) is validated and then skipped, so it is never composed at its list position. Group entries arrive through rt.middleware, so group nesting needs nothing extra. After the recovery wrapper (recoverJSON or recoverBare) and before recordPattern, wrap h in r.corsProfiles[profile].profileMiddleware when the route names a profile. Preflight routes keep their current path. Keep the cors factory registration in BuildRouter (the name must keep resolving and stay reserved for surf) and change its comment to say wrap applies the profile itself. bufferedResponse.commit: copy every buffered header key as today except Vary. Merge each comma-separated Vary value into the destination through addVary, so a Vary: Origin the profile set on the outer writer survives a handler that sets its own Vary. Preflights never pass through commit, so the bytes TestCORSOptionsMatchesLaravel pins must not change. Change the profileMiddleware doc comment: it runs outermost, outside the body limit, locale and recovery.
+
+Test in cors_profile_test.go, reusing the helpers: TestCORSProfileHeadersOnRefusals with spaProfileYAML, no http.cors, and a test plugin that registers three named middlewares: deny, which answers 401 without calling next, forbid, which answers 403 without calling next, and readall, which reads the whole body and answers 413 on *http.MaxBytesError. Subtests, each sending Origin https://www.example.com:
+- route [deny, cors:spa]: 401;
+- subtest guard_403, route [forbid, cors:spa]: 403;
+- a group Use(deny) whose route names cors:spa: 401;
+- [throttle:1,1, cors:spa]: the second request gets 429;
+- [body.limit:16, readall, cors:spa] with a 64-byte body: 413;
+- a handler that panics behind cors:spa: 500 (JSON);
+- a GroupRaw with cors:spa and a panicking handler: 500;
+- subtest turnstile_422: an app with a published bouncer.NewTurnstile("test-secret", false), as TestTurnstileMiddlewareSmoke publishes one, and a POST route [turnstile:closed, cors:spa]; a request without a token answers 422. The empty token is refused before any siteverify call, so no fake server is needed;
+- subtest turnstile_503: transportApp in the production environment with no turnstile.secret, POST route [turnstile:closed, cors:spa]: 503.
+The two Turnstile subtests assemble their own app, because BuildRouter builds one verifier per router. Every status the docs sentence below names (401, 403, 422, 503, 429, 413, 500) has a subtest here. Each asserts Access-Control-Allow-Origin equal to the origin, Access-Control-Allow-Credentials true and Vary containing Origin. One more case: [deny, cors:spa] with Origin https://evil.example.org gives 401 with no Allow-Origin and with Vary containing Origin. TestCORSProfileVaryKeptWithHandlerVary: a handler behind cors:spa sets Vary: Accept-Language, and the response's Vary names both Origin and Accept-Language. Add both names to SURF_TESTS in scripts/check-phase19.3.sh.
+
+Docs, in the same commit:
+- docs/services/routing.md "CORS profiles": replace the sentence that tells readers to list the profile beside the guard. The new text says the route (or its group) lists cors:spa among its middleware names, and surf applies the profile outside every other layer of the route, whatever its position in the list or the group nesting. Every response of the route therefore carries the profile's headers, including refusals from guards (401, 403), throttle (429) and Turnstile (422, 503), the body limit (413) and recovered panics (500); otherwise the browser would hide them from the page. Shorten the same statement into the cors:&lt;profile&gt; row of the middleware table.
+- modules/surf/README.md: the Features bullet on named CORS profiles gets the same statement, including the words "whatever its position".

+WR-04 (per D-04), surf/cors.go validateCORSConfig. These rules apply only when SupportsCredentials is true; non-credentialed configs keep loading exactly as today.
+- (a) An allowed_origins entry containing * (the bare * is already refused) is accepted only when its scheme is literal and every * is a whole leftmost host label followed by a dot, as in https://*.example.com.
+- (b) Every allowed_origins_patterns entry must start with ^ and end with $.
+- (c) No origin pattern may match any of the probe origins https://cors-probe.invalid, http://cors-probe.invalid, https://cors-probe.com and null (an unexported list). This covers the compiled wildcard entries too, and it catches https://*, *://*, https://*.com and ^https?://.*$.
+Each error names the key with its index (for example http.cors.allowed_origins[1] or http.cors_profiles.spa.allowed_origins_patterns[0]) and says what is accepted. Profiles get the same checks through LoadCORSProfiles. Regression: append rows to TestCORSCredentialsWildcardRefused. https://* and the unanchored https://.*\.example\.com are refused with credentials, and both still load without credentials. Docs:
+- routing.md credentials rules: list the three rules, including that patterns must be anchored with ^ and $;
+- surf README: the http.cors allowed_origins and allowed_origins_patterns rows mention them.
+Commit: `fix(19.3-06): credentialed CORS refuses wildcard-host and unanchored origins (WR-04)`.
+
+WR-05 (per D-03), bouncer/cookie.go LoadCookieConfig: in the production environment, a Secure that resolves to false is an error, whether auth.cookie.secure was set explicitly or inferred from an http or unset app.url. Keep the explicit-false message. For the inferred case, return an error prefixed bouncer: that contains "auth.cookie.secure resolves to false in the production environment", names app.url, and tells the reader to set app.url to an https URL or auth.cookie.secure: true. Non-production environments keep inferring false for an http app.url. Update the LoadCookieConfig doc comment. Regression: append rows to TestLoadCookieConfigErrors for production with app.url http and production with app.url unset. Docs: the auth.cookie.secure row in authentication.md and the error sentence below that table; the bouncer README Configuration row. Commit: `fix(19.3-06): production refuses an inferred insecure token cookie (WR-05)`.
+
+WR-09 (per D-03), withDefaults:
+- a CookieConfig equal to the zero value also gets Secure true; decide this before Name and Path are filled;
+- any config whose SameSite is the zero value gets http.SameSiteLaxMode;
+- a config with any field set keeps its Secure value.
+Confirm that TokenCookie, ForgetTokenCookie and both handlers go through withDefaults. Update the CookieConfig field docs and the withDefaults comment: SameSite is Lax when unset; Secure has no default except for the zero config, which is Secure; LoadCookieConfig derives Secure from app.url. Regression:
+- extend the zero-config assertions in TestTokenCookieAttributes to SameSite Lax and Secure;
+- a partial config ({Name: sid}) gets SameSite Lax and stays not Secure.
+Docs:
+- bouncer README: the CookieConfig row and the Cookie transport bullet;

+  <action>Three commits, one per finding, each with its docs.
+
+WR-06 (per D-17), apidocs.go:
+- The two external script tags carry nonce="{{.Nonce}}" next to their integrity and crossorigin attributes.
+- The Content-Security-Policy keeps the per-request nonce as the only script-src source: script-src 'nonce-n'; object-src 'none'; base-uri 'none'; frame-ancestors 'none'. There is no host source.
+- The CSS link and its SRI stay. Remove the CDN host constant if nothing else uses it. The version and the integrity values do not change.
+Regression: TestAPIDocsServesPinnedPage asserts that all three script tags carry the header's nonce and that the script-src directive has no https: source. Docs: the API documentation page paragraph in routing.md says scripts run only with the page's per-request nonce; the two jsDelivr scripts carry it as well as their SRI hash, so no other jsDelivr script can run. Update the matching surf README Features bullet. Commit: `fix(19.3-06): api-docs CSP allows only nonce-carrying scripts (WR-06)`.
+
+WR-07 (per D-12), attach:
+- A new exported error, ErrProtectedNeedsPrivateBucket. Its message names storage.uploads.public_url and says that a protected (is_public false) upload needs a private bucket: unset public_url or make the relation public.
+- Store returns it when Upload.Public is false and PublicURLBase() is not empty, before it reads the body or writes a blob. Public uploads, and any upload without public_url, behave as today.
+- OpenBucket's line about a set public_url moves from Info to Warn and says protected uploads are refused.
+- cabana answers an unknown Store error through its default branch (logged, opaque error). Leave cabana unchanged and record in the SUMMARY what the admin sees.
+Regression in url_test.go (package attach, so it can set the base): TestStoreProtectedNeedsPrivateBucket, using memblob and &gorm.DB{} as TestStoreSmokeRefusals does. With the base set, a Public false upload returns the error and leaves the bucket empty. Reset the base in t.Cleanup and do not mark the test parallel. Docs:
+- storage.md: the public_url paragraph says protected uploads are refused while public_url is set;
+- lagoon README: the attach bullet, an API reference row for attach.ErrProtectedNeedsPrivateBucket, and the storage.uploads.public_url configuration row.
+Commit: `fix(19.3-06): refuse protected uploads into a public_url bucket (WR-07)`.
+
+WR-08 (per D-18), router.go BuildRouter:
+- After the loop that wraps every route, count the routes whose middleware list names turnstile:open or turnstile:closed.
+- When the count is positive and the verifier from buildTurnstile has an empty Secret, log one warning through accessLogger(app). The message starts "surf: turnstile.secret is empty" and says that turnstile:open passes every request, while turnstile:closed passes outside production and answers 503 in production. The attributes are routes (the count) and production (the verifier's Production flag).
+- Never log the secret.
+- No warning when no route names turnstile, or when the secret is set.
+Regression in cors_profile_test.go: TestTurnstileEmptySecretWarnsAtBoot. Publish a *slog.Logger with a capturing handler on the app. Two turnstile routes and no secret give one warning with routes 2. A published verifier with a secret gives none, and so does an app without turnstile routes. Docs: the turnstile.secret rows in the surf README and in authentication.md mention the start-up warning. Commit: `fix(19.3-06): warn at boot when turnstile routes have no secret (WR-08)`.</action>

+  <action>Framework first, two commits.
+
+WR-02 (per D-10): NewSiteCachePurgerFor builds the client with a CheckRedirect that returns http.ErrUseLastResponse. A 3xx answer is never followed, so the bearer token never goes to the Location and the POST never turns into a GET. Purge logs the 3xx through the existing "cooler: site cache purge failed" warning with its status. Regression in sitecache_test.go: TestSiteCachePurgeNoRedirect. Receiver A answers 307 with a Location pointing at receiver B; B receives nothing; one failed warning carries status 307; no log line contains the token. Docs: "Timing and failures" in caching.md says redirects are not followed and are logged as failures with their status. Commit: `fix(19.3-06): site-cache purge never follows redirects (WR-02)`.
+
+WR-01 (per D-10 and D-11). The user's decision in this gap run supersedes plan 04's "one request per committed save, no debounce".
+
+Keep every exported name and signature: SiteCachePurger, NewSiteCachePurger, NewSiteCachePurgerFor, Purge, Endpoint, PurgeSiteCacheAfterCommit, SiteCacheFromApp and the constants. Purge stays the synchronous single send.
+
+Queue:
+- SiteCachePurger gets unexported queue state: a mutex, a sending flag, one pending kind and slug, a coalesced count, and an idle channel that is closed when a busy period ends.
+- An unexported enqueue(kind, slug). When nothing is in flight, it marks sending and starts one goroutine that sends. While a send is in flight, it replaces the pending body with the latest one and counts it.
+- The goroutine loops. It sends through the same code as Purge (a detached background context bounded by SiteCachePurgeTimeout). Then it takes the pending body, if any, and sends again. Otherwise it clears sending and closes idle.
+- The success and failure log lines keep their messages and attributes. They add coalesced only when it is above zero, so the existing cooler and Journal log assertions keep passing.
+
+After commit and shutdown:
+- PurgeSiteCacheAfterCommit registers an after-commit callback that calls enqueue. The admin request returns as soon as the commit's callbacks have queued. A nil purger still does nothing; outside a transaction the purge queues at once.
+- New exported method Wait(ctx context.Context) error. It returns nil at once for a nil or idle purger. Otherwise it blocks until the purger is idle, looping when a new busy period starts, or until ctx ends, then returning ctx.Err().
+- cooler.go: installSiteCache returns the purger it published, and Install keeps it on the Handle in an unexported field. Handle.Close first waits for it with a context bounded by SiteCachePurgeTimeout plus one second and ignores the deadline error. Then it closes the Redis client as today. Close no longer returns before the drain when there is no Redis client.
+- Update the doc comments:
+  - PurgeSiteCacheAfterCommit: queued after commit, fire and forget, at most one request in flight per purger, later saves collapse into one follow-up;
+  - Purge: the blocking send the queue uses;
+  - Wait.
+
+Existing tests:
+- The tests that count requests after PurgeSiteCacheAfterCommit call Wait before counting: the outside-a-transaction subtest, TestSiteCacheAfterCommitOnly and TestSiteCacheFailureNeverFails.
+- Every test that queues a purge waits before it returns, because captureLogs restores slog.Default afterwards.
+
+Regression: TestSiteCachePurgeAsyncCoalesced (Docker-free). A receiver blocks until released. Twenty PurgeSiteCacheAfterCommit calls with a nil db each return within 50 ms. After the release and Wait, the receiver has exactly two requests, the second carrying the last slug, and the purged log line of the second carries coalesced 18.
+
+Docs, in the same commit:
+- caching.md, rewrite "What a purge sends" and "Timing and failures":
+  - the purge is queued after commit and never blocks the save;
+  - at most one request is in flight per process;
+  - saves committed meanwhile collapse into one follow-up request, because each purge clears the whole route cache;
+  - Wait serves tests and commands;
+  - serve waits for a queued purge on shutdown, up to the timeout plus a second.
+- cooler README: the Features bullet; the API rows for PurgeSiteCacheAfterCommit and Purge; a new cooler.SiteCachePurger.Wait row.
+Commit: `fix(19.3-06): queue site-cache purges after commit and coalesce them (WR-01)`.
+
+Plugins, test-only, one commit per repository after the framework commit; plugin controllers and the Journal aliases stay untouched:
+- In site_cache_admin_test.go of sm-faq-plugin, sm-menu-plugin and sm-journal-plugin, every read of the purge receiver first drains the purger used by the app under test. That covers take, expectOnePurge, expectNone and the direct take calls. Drain through cooler.SiteCacheFromApp(the harness's app).Wait with a 5-second context, so each save's purge is asserted after it was sent. The probe and Seen assertions stay.
+- In sm-journal-plugin classes/site_cache_test.go, the outside-a-transaction subtest waits before reading hits, and its name says the purge is queued at once.
+Each commit: `test(19.3-06): wait for the queued site-cache purge before asserting (WR-01)`, staged by explicit path.
+
+Progress record, the last step of Task 4, after the three plugin commits and this task's verify (see "Context budget and resume point"). Write .planning/phases/19.3-framework-transport-and-infrastructure-for-wavepath/19.3-06-PROGRESS.md with:
+- a first line saying it is the mid-plan record of 19.3-06, superseded by 19.3-06-SUMMARY.md once that file exists;
+- the line `next: Task 5` on its own;
+- a Completed Tasks table for Tasks 1-4 in the executor's checkpoint shape: task, name, commit (repository, short hash and subject), key files, one row per commit;
+- the HEAD of summercms.go and of the six sibling repositories (the layers still at their planning-time heads);
+- each task's verify result, with the docker stage marked as run or NOT RUN;
+- the notes the SUMMARY needs from Tasks 1-4: deviations, decisions taken while executing, and what the admin shows for a refused protected upload (Task 3).

+  <action>Per D-10 and D-11. The model is the review's second option, an explicit opt-in. Restricting site_cache.purge_url to loopback would refuse at boot an https URL that Journal deployments may carry through the alias keys, which would break a core plugin. The default stays "refuse proxied".
+
+vue-faq-layer first, one commit:
+- server/lib/siteCachePurge.ts: SitePurgeAuthInput gains an optional allowProxied boolean. When it is true, authorizeSitePurge skips the proxied verdict, so the bearer token is the only gate (at least 32 characters, compared in constant time). The doc comments say so.
+- server/api/__site__/cache/purge.post.ts passes allowProxied from runtimeConfig.siteCache.allowProxied, accepting true or the string "true". Its header comment documents the flag.
+- nuxt.config.ts: runtimeConfig siteCache gains allowProxied: false. Its comment names NUXT_SITE_CACHE_ALLOW_PROXIED and says when to set it: the backend reaches the site through a TLS-terminating proxy, which adds X-Forwarded-For, X-Real-IP or Forwarded.
+- tests/sitePurge.test.ts, two new specs; the existing specs stay unchanged:
+  - "sitePurge: allowProxied lets a proxied request reach the token check": with allowProxied true, a proxied request is ok with the right bearer and unauthorized with a wrong one, and is still disabled without a token;
+  - "sitePurge: route accepts a proxied request with allowProxied and the right bearer": in the file's route-handler spec style, it answers 200 with the count, and the same request answers 404 with the flag false.
+- Recompute SHARED_LIB_SHA256 and SHARED_ROUTE_SHA256 once the lib and route are final.
+- README: the Site cache purge section documents the flag and the environment variable.
+- package.json: version 0.3.0.
+
+Then copy the three shared files byte for byte into vue-menu-layer and vue-journal-layer. Add the same nuxt.config.ts entry and README paragraph to each. Versions: 0.3.0 for menu, 0.5.0 for journal. One commit per repository. vue-journal-layer keeps the deprecated /api/__journal__/cache/purge alias and app/utils/siteCache.ts unchanged. No tags here; Task 7 creates them.
+
+Framework, one docs commit:
+- caching.md "Site cache purge" gains a paragraph that pairs an https purge_url on another host with NUXT_SITE_CACHE_ALLOW_PROXIED=true on the site. It explains that the proxy adds forwarding headers, which the route refuses by default. It also says that the token is then the only gate, so it must stay long and secret.
+- cooler README: the site_cache.purge_url configuration row points at that paragraph.
+

+    - Accepted: https://www.example.com, https://*.example.com, https://*.api.example.com:8443, ^https://[a-z]+\.example\.org$.
+    - Refused: https://*, *://*, https://*example.com, https://*.com, http*://www.example.com, the unanchored https://.*\.example\.com, ^https://.*\.example\.com without $, ^https?://.*$ and ^.*$.
+    - Each refusal names the key with its index, and every refused entry still loads without credentials.
+  - TestCORSAnchoredPatternNoSuffixMatch: a credentialed profile with ^https://[a-z]+\.example\.com$ answers https://www.example.com with the exact origin, and https://www.example.com.attacker.net without Allow-Origin but with Vary: Origin.
+- surf apidocs_test.go, TestAPIDocsCSPNoHostSource (per D-17): parse the Content-Security-Policy into directives.
+  - script-src holds exactly one source, 'nonce-n', and object-src 'none', base-uri 'none' and frame-ancestors 'none' are present.
+  - Every script tag in the body carries nonce n, and two requests get different nonces.
+  - The three integrity values are unchanged.
+- bouncer cookie_test.go (per D-03):
+  - TestLoadCookieConfigProductionInferredSecure, a table: production with app.url http, unset or malformed gives an error naming auth.cookie.secure and app.url; production with https gives Secure; production with an http app.url and auth.cookie.secure true gives Secure; development with http gives Secure false and no error.
+  - TestZeroCookieConfigDefaults: the zero config's TokenCookie and ForgetTokenCookie carry token, /, HttpOnly, SameSite Lax and Secure; {Name: sid} gets SameSite Lax and stays not Secure; a CookieRefreshHandler and a CookieLogoutHandler built from the zero config write Set-Cookie lines containing SameSite=Lax and Secure.
+- cooler sitecache_test.go (per D-10):
+  - TestSiteCachePurgeWaitAndClose:
+    - Wait on a nil purger and on an idle one returns nil at once.
+    - With a blocking receiver, Wait under an expired context returns context.DeadlineExceeded, and the queued purge is still sent after the release.
+    - Install with the site_cache keys (memory drivers, no Redis), then one queued purge, then Handle.Close: Close returns after the receiver got the request, and returns within SiteCachePurgeTimeout plus a second when the receiver hangs.
+  - TestSiteCacheBulkCommitCoalesced (Postgres harness, skips under -short), with a blocking receiver, in two scenarios:
+    - 25 purges registered inside one lagoon.Transaction;
+    - 10 separate transactions in a loop.
+    Each Transaction returns before the receiver is released, in under 500 ms. After the release and Wait, the receiver got exactly two requests per scenario, the second carrying the last slug.
+
+Gate, one commit `test(19.3-06): gate requires the review-fix tests`:
+- append to the lists:
+  - BOUNCER_TESTS: TestLoadCookieConfigProductionInferredSecure, TestZeroCookieConfigDefaults;
+  - SURF_TESTS: TestCORSCredentialedOriginRules, TestCORSAnchoredPatternNoSuffixMatch, TestAPIDocsCSPNoHostSource, TestTurnstileEmptySecretWarnsAtBoot;

+  - DOCKER_COOLER_TESTS: TestSiteCacheBulkCommitCoalesced;
+  - LAYER_REQUIRE: the two sitePurge names from Task 5.
+- Add one line to the header comment naming the plan-06 fixes (CR-01, WR-01..WR-09).
+- Run `PHASE193_REQUIRE_DOCKER=1 bash scripts/check-phase19.3.sh --all` on a Docker host.
+- Prove fail-closed: rename one new required test locally, check that the go stage exits non-zero, revert, and record the result in the SUMMARY.

+## Trust Boundaries
+
+| Boundary | Description |
+|----------|-------------|
+| browser on the SPA origin to a profiled API route | credentialed cross-origin requests whose answers the page must be able to read |
+| config to boot | CORS origins, cookie Secure, public_url and the Turnstile secret, validated or reported before serving |
+| Go app to the site's purge route | bearer-token POST, loopback or https through a proxy |
+| CDN scripts to the api-docs page | third-party code executed in the app's origin |
+| local checkouts to origin | tags and pushes that every consumer reads |
+
+## STRIDE Threat Register
+
+| Threat ID | Category | Component | Severity | Disposition | Mitigation Plan |
+|-----------|----------|-----------|----------|-------------|-----------------|
+| T-19.3-33 | Tampering | profiled-route refusals without `Vary: Origin` or CORS headers (a shared cache serving one origin's answer to another; the SPA blind to its 401) | medium | mitigate | the profile is applied outermost in `Router.wrap`; `bufferedResponse.commit` merges `Vary`; TestCORSProfileHeadersOnRefusals and TestCORSProfileVaryKeptWithHandlerVary in the gate |
+| T-19.3-34 | Information disclosure | credentialed CORS trusting arbitrary origins through `https://*`, `*://*` or unanchored patterns | high | mitigate | `validateCORSConfig` wildcard-label rule, anchoring rule and probe origins, globally and per profile; TestCORSCredentialedOriginRules, TestCORSAnchoredPatternNoSuffixMatch |
+| T-19.3-35 | Information disclosure | purge bearer token forwarded on a redirect (https to http on the same host) | high | mitigate | `CheckRedirect` returns `http.ErrUseLastResponse`; TestSiteCachePurgeNoRedirect asserts the Location receives nothing |
+| T-19.3-36 | Denial of service | synchronous per-row purges holding admin requests past server write timeouts | medium | mitigate | after-commit queue with one request in flight and coalescing; `Wait` and `Handle.Close` drain within the timeout plus a second; TestSiteCachePurgeAsyncCoalesced, TestSiteCacheBulkCommitCoalesced |
+| T-19.3-37 | Spoofing | purge route with `allowProxied` reachable from the network | medium | mitigate | opt-in flag, default false; the token stays at least 32 characters and is compared in constant time over sha256 digests; caching.md documents that the token is then the only gate; sitePurge specs cover both flag states |
+| T-19.3-38 | Information disclosure | auth token cookie without Secure in production through an http or unset `app.url` | high | mitigate | `LoadCookieConfig` boot error naming `auth.cookie.secure` and `app.url`; TestLoadCookieConfigProductionInferredSecure |
+| T-19.3-39 | Information disclosure | hand-built zero `CookieConfig` writing a cookie without SameSite or Secure | medium | mitigate | `withDefaults` gives the zero config Secure and every unset SameSite Lax; TestZeroCookieConfigDefaults |
+| T-19.3-40 | Elevation of privilege | api-docs CSP allowing any jsDelivr script (DOM XSS loading attacker code) | medium | mitigate | `script-src` holds only the per-request nonce; every script tag carries it; SRI kept; TestAPIDocsCSPNoHostSource |
+| T-19.3-41 | Information disclosure | protected (`is_public` false) files in a bucket served publicly through `public_url` | high | mitigate | `attach.Store` returns `ErrProtectedNeedsPrivateBucket` before writing; OpenBucket warns at boot; TestStoreProtectedNeedsPrivateBucket |
+| T-19.3-42 | Spoofing | `turnstile:*` routes unprotected by a missing secret, unnoticed | medium | mitigate | one boot warning with the route count and the production flag, never the secret; TestTurnstileEmptySecretWarnsAtBoot |
+| T-19.3-43 | Tampering | the three layer copies of the purge route drifting apart | low | mitigate | byte-identical files checked with `cmp` in the layers stage, sha256 pins updated in each spec |
+| T-19.3-44 | Tampering | publishing an unverified release, or a moved tag | medium | mitigate | Task 7 blocking checkpoint after the full gate; tags checked free on origin; no force-push |
+| T-19.3-SC | Tampering | npm/pip/cargo or Go module installs | high | mitigate | this plan installs nothing: no new Go module, no npm package; the plugin `go get` at release only moves the framework require to the tag this plan creates |

+- Task 1: PASS. `go vet ./...`, surf short suite, the five named CORS tests (5 top-level PASS), guard_403, turnstile_422 and turnstile_503 (3 subtest PASS), `check-phase19.3.sh go` passed, TestDocsTree ok. Both new tests failed against the old router.go (checked by restoring it locally, then the new file back). Tracer gate: automated verify re-run green, expansion continued.
+- Task 2: PASS. Surf and bouncer short suites, 7 top-level PASS, TestDocsTree ok.
+- Task 3: PASS. Vet in both tag modes, surf and lagoon short suites, 6 top-level PASS, TestDocsTree ok.
+- Task 4: PASS. `go test -short -race ./modules/cooler` ok, 5 top-level PASS, `check-phase19.3.sh plugins` passed, `check-phase19.3.sh docker` RUN and passed (Docker answered for user jin; framework cooler, cabana, attach suites and the FAQ, menu and Journal admin purge suites).
+
+## Notes for the SUMMARY
+
+Deviations:
+- [Rule 2 - docs] Task 1 also updated docs/architecture/request-lifecycle.md ("The wrapping order" list gains the CORS profile step), since the list would otherwise be wrong after the change. Same commit as CR-01.
+- [Rule 1 - test] Task 2 (WR-05): TestLoadCookieConfigDefaults had production rows with an http and an empty app.url expecting Secure false without error; they now run in development (the production case is an error by design and is covered in TestLoadCookieConfigErrors).
+- [Rule 1 - test] Task 4 (WR-01): ExampleSiteCacheFromApp printed the purge from the receiver synchronously; it now calls `cooler.SiteCacheFromApp(app).Wait` after the save, and the `purge` doc comment of the example controller says the purge is queued. docs/services/caching.md's src= copy was refreshed with `summer docs:sync`.
+- [Rule 1 - test] Task 4: "a slow receiver is abandoned and the save stays committed" now asserts the save returns within 500 ms (it no longer waits for the 2 s purge) and waits for the queue before reading the log.
+
+Decisions taken while executing:
+- CR-01: `Router.wrap` resolves the profile through `routeCORSProfile` (two profiles stay a boot error), skips the `cors:<profile>` entry in its loop after the unknown-profile check, and wraps the recovered handler in `profileMiddleware` just inside `recordPattern`. `bufferedResponse.commit` merges each comma-separated `Vary` value through `addVary`.
+- WR-04: anchoring is checked on the parsed expression (`regexp/syntax`): every alternative must begin with `^` and end with `$`, so `^a|b$` is refused as unanchored. Wildcard entries must be `<literal scheme>://*.<rest>` with one `*`. Probe origins: https://cors-probe.invalid, http://cors-probe.invalid, https://cors-probe.com, null.
+- WR-05: the explicit-false message stays; the inferred case says "auth.cookie.secure resolves to false in the production environment" and names app.url.
+- WR-09: the zero-config Secure is decided before Name and Path are filled; any unset SameSite becomes Lax.
+- WR-07: the check sits in `attach.Store` right after the argument checks, before the extension check and before the body is read.
+- WR-08: the warning goes through `accessLogger(app)` (the published `*slog.Logger`, else `slog.Default`) with attributes `routes` and `production`.
+- WR-01: `installSiteCache` returns the purger in effect, also one a plugin published before Install (the Journal alias keys), so `Handle.Close` drains whichever purger the app uses. Queued sends use a background context bounded by `SiteCachePurgeTimeout`. Log lines add `coalesced` only when above zero. `Purge` tolerates a nil client field (falls back to a no-redirect client).
+- Plugin tests: `purgeReceiver` gains a `drain` hook set by `drainFrom(t, app)`; `take` (and so `expectOnePurge` and `expectNone`) waits on `cooler.SiteCacheFromApp(app).Wait` with a 5 s context first. In TestCategoriesAdminFrameworkKeysWin both receivers drain the app's purger.
+
+What the admin shows for a refused protected upload (Task 3, WR-07): cabana's `writeFileError` has no branch for `attach.ErrProtectedNeedsPrivateBucket`, so it reaches the default path: `logFileFailure` logs the error (its message names storage.uploads.public_url) and the client gets the generic opaque 500 error body. cabana is unchanged, as planned.
+
+Acceptance notes:
+- The `git log --oneline --grep='(WR-0N)$'` checks of Tasks 2 and 3 print 4 and 5 lines rather than 3: commits of earlier phases (02) also end with `(WR-04)` and `(WR-07)`. The three 19.3-06 commits per task are present.
+- `grep -n 'cooler.SiteCachePurger.Wait' modules/cooler/README.md` prints two lines (the Features bullet and the API row); Task 5's cooler README edit rewords the bullet so only the API row names it.

+# Phase 19.3 Plan 06: Review gap closure (CR-01, WR-01..WR-09) Summary
+
+**cors:&lt;profile&gt; now decorates every response of a profiled route including guard, Turnstile, throttle, body-limit and panic refusals; credentialed CORS, cookie Secure, api-docs CSP, protected uploads and Turnstile secrets are checked at boot; site-cache purges are redirect-free, queued and coalesced, and the layers accept proxied purges on an explicit allowProxied opt-in. Release handed off to the phase 19.3 main session.**
+
+## Performance
+
+- **Duration:** about 40 min of execution (two executor contexts, split after Task 4)
+- **Started:** 2026-10-15T20:20:38Z
+- **Last task commit:** 2026-10-15T20:51:13Z
+- **Completed:** 2026-10-15T21:00Z (SUMMARY)
+- **Tasks:** 6 of 7 executed; Task 7 (release checkpoint) handed off
+- **Files modified:** 24 in summercms.go (excluding .planning), 4 test files in three plugins, 6 files in each of three layers
+
+## Accomplishments
+
+- **CR-01 (verification gap closed):** a cross-origin SPA reads every refusal of a `cors:<profile>` route: 401/403 from a guard listed before the profile or set on the group, Turnstile 422/503, 429, 413 and a recovered 500 in JSON and raw groups all carry Allow-Origin, Allow-Credentials and `Vary: Origin`; a disallowed origin gets `Vary: Origin` only; a handler's own `Vary` is merged.
+- **WR-04:** with `supports_credentials`, wildcard entries other than a whole leftmost host label, unanchored patterns and patterns matching probe origins outside the configured domains fail boot naming key and index, globally and per profile. Non-credentialed configs unchanged (`TestCORSOptionsMatchesLaravel` green).
+- **WR-05 / WR-09:** production refuses a token cookie whose Secure resolves to false, set or inferred from an http/unset `app.url`; zero `CookieConfig` writes `token`, `Path=/`, HttpOnly, SameSite=Lax, Secure.
+- **WR-06:** `/api-docs` sends `script-src 'nonce-…'` as the only source; every script tag carries the nonce; SRI unchanged.
+- **WR-07:** `attach.Store` returns `attach.ErrProtectedNeedsPrivateBucket` before any blob is written when `is_public` is false and `storage.uploads.public_url` is set; `OpenBucket` warns at boot.
+- **WR-08:** `BuildRouter` logs one warning naming the route count when turnstile routes exist and the secret is empty.
+- **WR-02 / WR-01:** the purge client never follows a redirect; `PurgeSiteCacheAfterCommit` only enqueues after commit; one request in flight per purger, saves committed meanwhile collapse into one follow-up (bulk delete of N rows sends at most two); `cooler.SiteCachePurger.Wait`; `Handle.Close` drains. Exported cooler purge names, Journal aliases and the FAQ, menu and Journal controllers unchanged.
+- **WR-03:** the shared layer purge route honours `siteCache.allowProxied` / `NUXT_SITE_CACHE_ALLOW_PROXIED`; the three shared files are byte-identical (sha256 `0ea9f0f9…193b260e`) with updated hash pins; `docs/services/caching.md` pairs an https `purge_url` on another host with the flag.
+- **Gate:** 11 Go tests and 2 layer specs added to the required lists; the whole gate passes with Docker.

+summercms.go commits measured from the ledger: `git rev-list --count e9ad640..0c8109c` = 14 (12 code/docs plus 2 planning-docs commits).
+
+## Task 7: handed off
+
+The release checkpoint was reached with every pre-check green (see Verification). The human's reply, verbatim:
+
+> "ok, differently. there is main agent that was doing 19.3 phase and he was waiting for gap closure to update /docs and make a release then. in other words, you can finalize your gap closure, write SUMMARY.md and leave him the rest - he will update docs for whole phase 19.3, create a tag and do a release."
+
+Outcome: none of the three options (release / tag-only / hold) was executed by this plan. Proposed tag at the checkpoint: **v0.1.28**. Nothing was pushed or tagged in any repository; no plugin `go.mod` was changed.
+
+## Handoff to the phase 19.3 main session
+
+State at handoff:
+- summercms.go `master` at `0c8109c` plus this plan's SUMMARY and tracking commits, 20+ commits ahead of `origin/master` (includes planning commits since v0.1.27). Highest tag v0.1.27; v0.1.28 free on origin.
+- sm-faq-plugin, sm-menu-plugin, sm-journal-plugin: each 1 commit ahead of `origin/main` (the WR-01 test commits above).
+- vue-faq-layer, vue-menu-layer, vue-journal-layer: each 1 commit ahead of `origin/main`; v0.3.0 / v0.3.0 / v0.5.0 free on origin.
+
+What remains, in order:
+1. Whole-phase docs update for 19.3 (`docs/`); this plan's docs changes are already committed (routing, authentication, storage, caching, request-lifecycle, the four module READMEs).
+2. Annotated tag `v0.1.28` on summercms.go `master`; push `master`, then the tag.
+3. In each plugin (sm-faq-plugin, sm-menu-plugin, sm-journal-plugin): `GOWORK=off go get git.golem15.com/golem15/summercms@v0.1.28`, `GOWORK=off go mod tidy`, `GOWORK=off go vet ./...`, `GOWORK=off go test -count=1 ./...`; commit go.mod and go.sum as `chore: require summercms v0.1.28` (plan wording: `chore(19.3-06): require summercms v0.1.28`); push main. Required: the plugin tests now call `cooler.SiteCachePurger.Wait`, so the plugins do not build on origin without go.work until this bump.
+4. Push the three layer mains, then create and push annotated tags v0.3.0 (vue-faq-layer), v0.3.0 (vue-menu-layer), v0.5.0 (vue-journal-layer).
+5. Follow-up, out of scope here: app layer pins (sites get `siteCache.allowProxied` only after their pins move) and plugin submodule pointer bumps in apps.
+6. g15office phase comment (skipped here; to be posted with the release).
+
+## Files Created/Modified
+
+- `modules/surf/router.go`, `modules/surf/cors.go`: profile applied outermost, Vary merge, credentialed origin rules with probe origins, Turnstile boot warning.
+- `modules/surf/apidocs.go`: nonce on every script tag, nonce-only script-src.
+- `modules/bouncer/cookie.go`: production Secure rule, zero-config defaults.
+- `modules/lagoon/attach/store.go`, `bucket.go`: `ErrProtectedNeedsPrivateBucket`, boot warning.
+- `modules/cooler/sitecache.go`, `cooler.go`: no-redirect client, queue and coalescing worker, `Wait`, drain on `Handle.Close`.
+- `scripts/check-phase19.3.sh`: CR-01 tests in SURF_TESTS, plan-06 tests in BOUNCER/SURF/ATTACH/COOLER/DOCKER_COOLER lists and LAYER_REQUIRE.
+- Module READMEs and `docs/services/{routing,authentication,storage,caching}.md`, `docs/architecture/request-lifecycle.md`.
+- Plugin `site_cache_admin_test.go` (three plugins) and `sm-journal-plugin/classes/site_cache_test.go`: wait for the queued purge.
+- Layers: shared `siteCachePurge.ts` and `purge.post.ts`, specs with new hash pins, `nuxt.config.ts`, README, version bump.
+
+## Decisions Made
+
+- CR-01: `Router.wrap` resolves the profile through `routeCORSProfile` (two profiles stay a boot error), skips the `cors:<profile>` entry after the unknown-profile check and wraps the recovered handler in `profileMiddleware` just inside `recordPattern`; `bufferedResponse.commit` merges each comma-separated `Vary` value through `addVary`.
+- WR-04: anchoring checked on the parsed expression (`regexp/syntax`): every alternative must begin with `^` and end with `$`, so `^a|b$` is refused. Wildcards must be `<literal scheme>://*.<rest>` with one `*`. Probe origins: https://cors-probe.invalid, http://cors-probe.invalid, https://cors-probe.com, null.
+- WR-05: the explicit-false message stays; the inferred case says "auth.cookie.secure resolves to false in the production environment" and names app.url.
+- WR-09: zero-config Secure is decided before Name and Path are filled; any unset SameSite becomes Lax.
+- WR-07: the check sits in `attach.Store` right after the argument checks, before the extension check and before the body is read. In the admin, cabana's `writeFileError` has no branch for the new error, so it reaches the default path: `logFileFailure` logs the error (its message names `storage.uploads.public_url`) and the client gets the generic opaque 500. cabana unchanged, as planned.
+- WR-08: the warning goes through `accessLogger(app)` with attributes `routes` and `production`.
+- WR-01: `installSiteCache` returns the purger in effect, also one a plugin published before Install (Journal alias keys). Queued sends use a background context bounded by `SiteCachePurgeTimeout`. Log lines add `coalesced` only when above zero. `Purge` tolerates a nil client field.
+- WR-03: explicit opt-in, default stays "refuse proxied"; accepts `true` or the string `"true"` from runtimeConfig.
+- Plugin tests: `purgeReceiver` gains a `drain` hook set by `drainFrom(t, app)`; `take` (so `expectOnePurge` and `expectNone`) waits on `cooler.SiteCacheFromApp(app).Wait` with a 5 s context first. In TestCategoriesAdminFrameworkKeysWin both receivers drain the app's purger.
+- Task 7: release handed off to the phase 19.3 main session.
+
+## Deviations from Plan
+
+### Auto-fixed Issues
+
+**1. [Rule 2 - Docs] request-lifecycle wrapping order**
+- **Found during:** Task 1
+- **Issue:** `docs/architecture/request-lifecycle.md` "The wrapping order" list would be wrong after CR-01.
+- **Fix:** the list gains the CORS profile step.
+- **Commit:** `0723536`
+
+**2. [Rule 1 - Test] Production cookie rows moved to development**
+- **Found during:** Task 2 (WR-05)
+- **Issue:** `TestLoadCookieConfigDefaults` had production rows with http and empty `app.url` expecting Secure false without error, now an error by design.
+- **Fix:** those rows run in development; the production case is covered by `TestLoadCookieConfigErrors` and `TestLoadCookieConfigProductionInferredSecure`.
+- **Commit:** `4dae833`
+
+**3. [Rule 1 - Test] ExampleSiteCacheFromApp waits for the queued purge**
+- **Found during:** Task 4 (WR-01)
+- **Issue:** the example printed the purge synchronously from the receiver.
+- **Fix:** it calls `cooler.SiteCacheFromApp(app).Wait` after the save; the example controller's `purge` comment says the purge is queued; `docs/services/caching.md` src= copy refreshed with `summer docs:sync`.
+- **Commit:** `db6a7f5`
+
+**4. [Rule 1 - Test] Slow-receiver subtest asserts the save is not blocked**
+- **Found during:** Task 4
+- **Issue:** "a slow receiver is abandoned and the save stays committed" waited for the 2 s purge.
+- **Fix:** asserts the save returns within 500 ms and waits for the queue before reading the log.
+- **Commit:** `db6a7f5`
+
+**5. Task 7 not executed as specified**
+- The checkpoint answer was none of release / tag-only / hold; the release moved to the phase 19.3 main session (see Handoff).
+
+**Total deviations:** 4 auto-fixed (1 docs, 3 test), 1 scope handoff. No CLAUDE.md-driven adjustments.
+
+## Verification
+
+- Tasks 1-4: per-task verify PASS (details in 19.3-06-PROGRESS.md): vet in both tag modes, surf/bouncer/lagoon/cooler short suites, `go test -short -race ./modules/cooler`, `check-phase19.3.sh go`, `plugins` and `docker` (RUN). Both CR-01 tests failed against the old router.go. Tracer gate: automated verify re-run green before expansion.
+- Task 5: `check-phase19.3.sh layers` passed, both new sitePurge specs `ok` in each layer, shared files byte-identical, TestDocsTree and `summer docs:build --check` ok.
+- Task 6: `PHASE193_REQUIRE_DOCKER=1 bash scripts/check-phase19.3.sh --all` passed; TestDocsTree and `examples/hello` tests passed.
+- **Fail-closed proof (Task 6):** renaming `TestZeroCookieConfigDefaults` locally made `bash scripts/check-phase19.3.sh go` exit 1 ("refuse: required tests did not pass: TestZeroCookieConfigDefaults"); reverted, never committed.
+- Task 7 pre-checks: `bash scripts/check-phase19.3.sh --all` passed all stages including docker (RUN); TestDocsTree and examples/hello passed; v0.1.28 free on origin; v0.3.0 / v0.3.0 / v0.5.0 free on the layer origins.
+
+Acceptance quirks:
+- `git log --oneline --grep='(WR-04)$'` and `(WR-07)$` print more than three lines: phase-02 commits end with the same suffixes. The three 19.3-06 commits per task are present.
+- The cooler README Features bullet was reworded in `4d4e379` so `cooler.SiteCachePurger.Wait` appears only in the API row.
+
+## Issues Encountered
+
+None blocking. Info findings IN-01..IN-11 left open, as planned.
+
+## User Setup Required
+
+Sites whose backend reaches the purge route through a TLS-terminating proxy set `NUXT_SITE_CACHE_ALLOW_PROXIED=true` after moving their layer pin (follow-up, see Handoff).
+
+## Next Phase Readiness
+
+Gap closure complete in code, docs and tests. The phase 19.3 main session finishes the whole-phase docs update and the release (Handoff, steps 1-6), then `/msd-verify-work 19.3`.
+
+## Self-Check: PASSED
+
+All 14 summercms.go commits, the 3 plugin commits and the 3 layer commits verified with `git cat-file -e`; plan_head_before/after measured from the ledger base e9ad640.

+# Phase 19.3: Framework transport and infrastructure for WavePath - Context
+
+**Gathered:** 2026-10-15
+**Status:** Ready for planning
+
+<domain>
+## Phase Boundary
+
+The framework gains the transport and infrastructure pieces a multi-client, multi-instance application needs:
+
+- JWT cookie transport for refresh across subdomains.
+- Credentialed CORS.
+- A cache module with memory and Redis drivers, plus a Redis-backed `surf.Store` so rate limits hold across instances.
+- An S3 blob option selected through config.
+- An opt-in `/api-docs` page and `/api-docs.json`.
+- Cloudflare Turnstile verification.
+
+Two todos are folded in: a framework-level site-cache purge service, adopted by the Journal, menu and FAQ plugins, and hardening of upload disk-name extensions.
+
+Framework code never names WavePath or any other application (READMEs, docs and examples use neutral names). Repos touched: `summercms.go`. For the purge adoption only: `sm-journal-plugin`, `sm-menu-plugin`, `sm-faq-plugin` and the matching vue layers (`vue-journal-layer`, `vue-menu-layer`, `vue-faq-layer`).
+
+Not in this phase: OIDC (19.4), social login (19.5), 2FA and device flow (19.6), and plugin-registrable token scopes (dropped, see the division note).
+
+</domain>
+
+<decisions>
+## Implementation Decisions
+
+### Cookie transport (bouncer)
+- **D-01:** `bouncer` ships config-driven cookie builders (`TokenCookie` and `ForgetTokenCookie` or similar) and an optional ready-made cookie refresh/logout handler. The handler reads the token cookie, calls the existing `Refresh*` path (which already rotates the token and blacklists the old JTI) and sets the rotated cookie. The app supplies a writer func so it keeps its own response envelope. The shared `sm-user-plugin` is NOT changed to set cookies; apps opt in.
+- **D-02:** Cookie attributes live in one framework block, `auth.cookie.*`: `name`, `domain`, `secure`, `same_site`, `path`. Cookie Max-Age comes from the guard's `refresh_ttl`, not its `ttl`: the cookie must outlive the access token, or refresh has no cookie to read (PHP comment in `AuthApiController::tokenCookie`). The existing per-guard `ttl`/`refresh_ttl` keys (`golem15.user.jwt.*`, `admin.jwt.*`) stay where they are. — **Reversibility:** costly — apps' config files and deploy docs reference these keys once they ship.
+- **D-03:** Defaults when unset match PHP: name `token`, path `/`, httpOnly, `SameSite=Lax`, no Domain (host-only), Secure when the app URL is https, Max-Age = refresh window (20160 min default).
+
+### Credentialed CORS (surf)
+- **D-04:** Harden the existing path-scoped `http.cors` (`surf.CORSConfig.SupportsCredentials`):
+  - Refuse, or at least loudly reject at boot, credentials combined with a `*` origin.
+  - Always echo the exact origin, and set `Vary: Origin` on preflight too.
+  - Test the api ↔ www subdomain case.
+- **D-05:** Also add a named CORS middleware (for example `cors:<profile>`) so a route group can carry its own CORS policy on top of the global path-scoped one.
+
+### Cache and rate-limit store (new module `cooler`)
+- **D-06:** New module **`cooler`** for the cache. The name comes from the research: `.planning/research/ARCHITECTURE.md` lists `cooler` for "in-process cache, rate-limit buckets", and `IDEA_LIB_NAMES.md` has `summer-cooler`. It gets a beach-name README and a row in the root table.
+- **D-07:** Redis client is **go-redis v9** (`github.com/redis/go-redis/v9`). A decision note under `.planning/notes/` names it before code lands. The memory driver is otter v2 (research/go-ecosystem.md) or a stdlib map; the researcher picks one and the note records it. — **Reversibility:** costly — every Redis-touching module and app config builds on this client.
+- **D-08:** The cache API is a Laravel-core subset: Get, Set, Has, Forget, Remember, Increment and Flush, with TTL and a per-app key prefix. No tags. An atomic lock only if a 19.x port is shown to need it.
+- **D-09:** Selection uses one shared Redis block, `redis.url`, plus `cache.driver: memory|redis` and `http.rate_limit.store: memory|redis`. The framework wires everything at boot, so apps import nothing. `cooler` implements `surf.Store` for Redis (an atomic fixed-window script with the same semantics as `surf.MemoryStore`), so `surf` takes no Redis dependency.
+
+### Site-cache purge (folded todo, in `cooler`)
+- **D-10:** A framework purge service in `cooler`:
+  - One configured target: `site_cache.purge_url` and `site_cache.purge_token`.
+  - A loopback POST with a bearer token, sent after a committed admin save.
+  - Failures are logged and never fail the save.
+- **D-11:** Plugin adoption is in this phase:
+  - Journal moves onto the service. Its current `golem15.journal.site_cache.*` keys stay as aliases for one release.
+  - The menu plugin purges after a menu or menu-entry save, reorder or delete. The FAQ plugin purges after a FAQ save or delete.
+  - The Nuxt purge route moves out of `vue-journal-layer` to a shared place, so a site without Journal still gets purges.
+  - Plugin repos are committed and pushed first; pointer bumps in apps are separate commits.
+  - Core plugins must not break: the alias keys keep existing Journal deployments working.
+
+### S3 and uploads (lagoon/attach)
+- **D-12:** New key `storage.uploads.public_url`. When set (a bucket or CDN base), `File` URLs are that base plus the partition path. When unset, files go through the existing `/storage/uploads` proxy route, which works for S3 too.
+- **D-13:** The S3 driver (`gocloud.dev/blob/s3blob`) is opt-in through a **build tag**. `summer build` sets the tag from `summer.yaml`, so an app still never imports the driver itself. A `bucket_url: s3://…` in a binary built without the tag must fail at boot with an error that names the tag.
+- **D-14:** S3-compatible endpoints (MinIO, R2, Hetzner) are configured through gocloud's native `bucket_url` query (`region`, `endpoint`, `use_path_style`). Credentials come from the standard AWS env vars. No parallel `s3.*` key set.
+- **D-15:** Folded stored-XSS fix: `attach.Store` takes the disk-name extension from the sniffed MIME type, through one shared helper. The client name stays only in `file_name`. A regression test checks that a PNG uploaded as `x.html` gets a `.png` disk name and URL. The deploy docs gain a note on nosniff and a file-type allow-list. App call sites (fonoteka `storeUpload`/`StorePublicFile`) move to the helper in a follow-up, not in this phase.
+
+### API docs (surf)
+- **D-16:** The spec is supplied by an app or plugin: an embedded YAML or JSON file, converted to JSON once and cached. This matches PHP, which serves a hand-written YAML covering only the public surface. Nothing is generated from swag here.
+- **D-17:** Routes are opt-in through config (`http.api_docs.enabled` plus the path), off by default. `/api-docs` serves a Swagger UI page from pinned jsDelivr `swagger-ui-dist@5` with SRI, like PHP. `/api-docs.json` serves the spec. Both are public and unauthenticated.
+
+### Turnstile (bouncer)
+- **D-18:** `bouncer` gets a Turnstile verifier, `Verify(ctx, token, ip, failClosed)`, with a 5 s timeout, plus a named middleware factory such as `turnstile:open|closed`. Semantics follow PHP `TurnstileVerifier`:
+  - Fail-open: an empty secret passes (dev no-op, the registration path).
+  - Fail-closed: 503 when unconfigured in production, 422 on a missing token, a siteverify false, an exception or a timeout (the guest entry path).
+  - Error bodies come from a writer func, so the app keeps the PHP shape. The secret is read from config, which maps the `TURNSTILE_*` env.
+
+### Module placement
+- **D-19:** `cooler` holds the cache, the Redis `surf.Store` adapter and the site-cache purge. `surf` holds `/api-docs` and the named CORS middleware. `bouncer` holds the cookie helpers and handler, and Turnstile. `lagoon/attach` holds the S3 tag, `public_url` and the extension fix.
+
+### Claude's Discretion
+- The exact Go identifiers, the handler signatures and the name of the named-CORS-middleware profile config.
+- otter vs a stdlib map for the memory cache driver (recorded in the decision note).
+- Whether the token cookie builder lives on a guard or as free functions.
+- The exact build-tag name and how `summer.yaml` declares it.
+
+### Folded Todos
+- **Purge the Nuxt site cache on menu and FAQ admin saves** (`.planning/todos/pending/site-cache-purge-for-menu-and-faq.md`, g15office `zugdxorb`). Today the purge is Journal-specific, so menu and FAQ edits show up only after the 300 s SWR TTL. Folded as D-10 and D-11 with full plugin adoption.
+- **Uploads keep the client file extension (stored XSS)** (`.planning/todos/pending/2026-10-11-uploads-keep-client-extension-stored-xss.md`, g15office `bemfi2zs`). Folded as D-15. Only the framework side is in scope; fonoteka call sites are a follow-up.

+
+<code_context>
+## Existing Code Insights
+
+### Reusable Assets
+- `modules/bouncer/refresh.go`: `Refresh`, `RefreshAudience` and `RefreshAudienceFor` already rotate the token and blacklist the old JTI with a grace window. The cookie handler wraps these.
+- `modules/bouncer/jwt.go`: `NewJWTGuard` and `NewBackendJWTGuard` already read tokens from configured cookie names after the bearer token.
+- `modules/bouncer/blacklist.go`: the `BlacklistStore` interface. A Redis implementation in `cooler` is a natural extra, but it is not required.
+- `modules/surf/cors.go`: `CORSConfig` (Laravel `config/cors.php` keys, including `supports_credentials` and origin patterns) and `pathScopedCORS`.
+- `modules/surf/limiter_store.go`: the `surf.Store` interface (`Attempt(key, max, decay)`) and `MemoryStore`. The Redis store must match its semantics.
+- `modules/lagoon/attach/bucket.go`: `OpenBucket` and `normalizeBucketURL` on `gocloud.dev/blob` (file and mem blank-imported today). S3 is the `s3blob` driver behind a build tag.
+- `modules/lagoon/attach/store.go`: `Store` already sniffs the content type, which is where the disk-name extension fix goes.
+- `../sm-journal-plugin/classes/site_cache.go`: the existing Journal purge to generalise.
+- `internal/build`: generates `main.go` and `plugins.gen.go` from `summer.yaml`, which is where build tags get set.
+
+### Established Patterns
+- Opt-in routes gated by config (`storage.uploads.serve` mounts the uploads route in `surf.BuildRouter`). `/api-docs` follows the same pattern.
+- Named middleware and middleware factories (`RegisterMiddlewareFactory`, `name:param`). Turnstile and named CORS use them.
+- Per-guard JWT config keys (`golem15.user.jwt.ttl/refresh_ttl`, `admin.jwt.*`).
+- New dependencies need a decision note first. YAML goes through `goccy/go-yaml`.
+
+### Integration Points
+- Boot wiring: the framework reads `redis.url`, `cache.driver` and `http.rate_limit.store` and installs the `cooler` Redis store into surf's limiter before routes are built.
+- `summer build` and `summer.yaml`: the S3 build tag.
+- Plugins (Journal, menu, FAQ): call the purge service after committed admin saves.
+
+</code_context>
+
+<specifics>
+## Specific Ideas
+
+- The cookie must outlive the access token (Max-Age = `refresh_ttl`). The PHP comment explains the re-login loop that happens otherwise.
+- Swagger UI is pinned to `swagger-ui-dist@5` on jsDelivr, as in PHP.
+- Turnstile keeps the two PHP modes exactly: registration fails open, guest entry fails closed.
+
+</specifics>
+
+<deferred>
+## Deferred Ideas
+
+- Switching fonoteka.go's `storeUpload`/`StorePublicFile` to the new extension helper: a follow-up quick task in fonoteka.go.
+- Cache tags and atomic locks: add them only when a ported plugin needs them.
+- Generating `/api-docs` specs from swag annotations for frontend routes: later, if wanted.
+- A Redis-backed `bouncer.BlacklistStore`: optional, not required by the criteria.
+
+### Reviewed Todos (not folded)
+- **Benchmark Płytarium on WinterCMS vs SummerCMS** (`2026-10-01-benchmark-...`): matched on keywords only; unrelated to 19.3.
+- **Port the FAQ plugin as sm-faq-plugin**: already its own repo; only the purge wiring touches it here.

+| Turnstile in surf instead | | |
+| Purge in its own module | | |
+
+## Claude's Discretion
+
+- Go identifiers, handler signatures, the named CORS profile config, otter vs stdlib map, the build-tag name.

+## Pattern Assignments
+
+### `modules/cooler/README.md` (doc)
+**Analog:** `modules/postcard/README.md` lines 1-30. Structure to copy:
+```markdown
+# postcard
+
+Transactional mail from plugin-owned Markdown templates ... SMTP driver.
+
+`import "git.golem15.com/golem15/summercms/modules/postcard"`
+
+**Name:** What you send home in summer; it delivers the application's mail.
+
+## Overview
+## Role in the framework
+## Features
+## Usage
+```
+Then API reference, Configuration (`redis.url`, `cache.driver`, `cache.prefix`, `cache.memory.max_entries`, `http.rate_limit.store`, `site_cache.purge_url`, `site_cache.purge_token`), Dependencies (go-redis v9, otter v2), Testing. Root `README.md` row format (line 110):
+```markdown
+| [postcard](modules/postcard/README.md) | <summary sentence> | <mnemonic> |
+```
+
+### `modules/cooler/cooler.go` (service, publish at boot)
+**Analog:** `modules/postcard/mailer.go` lines 85-110
+```go
+func Activate[P interface{ ID() string }](app *backpack.App, _ []P) error {
+	if app == nil {
+		return fmt.Errorf("postcard: app is nil")
+	}
+	driver, opts, err := driverFromApp(app)
+	if err != nil {
+		return err
+	}
+	m := &mailer{ ... }
+	if err := app.Publish[Mailer](m); err != nil {
+		return fmt.Errorf("postcard: %w", err)
+	}
+	return nil
+}
+```
+Copy: nil-app guard, `driverFromApp`-style config read (default `memory`), publish under the interface type (`app.Publish[cooler.Cache]`), errors prefixed `cooler:`. Never put `redis.url` in an error (RESEARCH Pitfall 7).
+
+### `modules/cooler/ratelimit.go` (Redis `surf.Store`)
+**Analog:** `modules/surf/limiter_store.go` lines 11-13 (interface) and 68-93 (semantics to match)
+```go
+type Store interface {
+	Attempt(key string, max int, decay time.Duration) (allowed bool, attempts int, retryAfter time.Duration)
+}
+...
+	if !ok {
+		e = &counterEntry{count: 0, resetAt: now.Add(decay)}
+		s.entries[key] = e
+	}
+	retryAfter := e.resetAt.Sub(now)
+	if retryAfter < 0 { retryAfter = 0 }
+	if e.count >= max { return false, e.count, retryAfter }
+	e.count++
+	return true, e.count, retryAfter
+```
+Implement structurally (do NOT import surf). Lua script from RESEARCH Pattern 2; fallback to a `MemoryStore` passed in by surf on Redis error. Keys `<prefix>rl:`.
+
+### `modules/cooler/memory.go`
+**Analog:** `MemoryStore` (same file above) for lifecycle (constructor + `Close`/stop). Use otter v2 per RESEARCH "Code Examples"; keys `<prefix>cache:`.
+
+### `modules/cooler/sitecache.go` (move)
+**Analog:** `../sm-journal-plugin/classes/site_cache.go` (whole file, ~185 lines). Copy verbatim, changing: key constants to `site_cache.purge_url` / `site_cache.purge_token`; log prefix `journal:` to `cooler:`; drop Journal-specific doc wording. Key pieces:
+```go
+const (
+	SiteCachePurgeTimeout = 2 * time.Second
+	siteCacheAnswerLimit = 4 << 10
+)
+const SiteCachePurgeMinTokenLength = 32
+
+func NewSiteCachePurger(purgeURL, token string) (*SiteCachePurger, error) // nil,nil when both empty; loopback-only http
+func (p *SiteCachePurger) Purge(ctx context.Context, kind, slug string) {
+	if p == nil { return }
+	ctx, cancel := context.WithTimeout(context.WithoutCancel(ctx), SiteCachePurgeTimeout)
+	...
+	req.Header.Set("Authorization", "Bearer "+p.token)
+	...
+	log.Warn("journal: site cache purge failed", "kind", kind, "slug", slug, "error", purgeTransportError(err))
+}
+func PurgeSiteCacheAfterCommit(ctx context.Context, db *gorm.DB, p *SiteCachePurger, kind, slug string) {
+	if p == nil { return }
+	lagoon.AfterCommit(ctx, db, func(ctx context.Context, _ *gorm.DB) { p.Purge(ctx, kind, slug) })
+}
+```
+Add a context-only helper (cabana tx lookup) modelled on `../sm-journal-plugin/controllers/site_cache.go`:
+```go
+purger, ok := a.Lookup[*classes.SiteCachePurger]()
+if !ok || purger == nil { return nil, nil }
+tx, ok := cabana.TxFromContext(ctx)
+```
+Note: cooler importing cabana would risk a cycle (cabana is heavy); prefer the helper taking `*gorm.DB` and let plugins call `cabana.TxFromContext` themselves, as Journal does. Add burst coalescing (RESEARCH Pattern 8).
+
+### `modules/cooler/*_test.go`
+**Docker analog:** `modules/postcard/mailpit_test.go` lines 35-60 (per-test `testcontainers.Run` with `testing.Short()` skip):
+```go
+if testing.Short() { t.Skip("requires testcontainers mailpit") }
+ctr, err := testcontainers.Run(ctx, mailpitImage,
+	testcontainers.WithExposedPorts("1025/tcp", "8025/tcp"),
+	testcontainers.WithWaitStrategy(wait.ForListeningPort("1025/tcp"), ...),
+)
+t.Cleanup(func() { _ = testcontainers.TerminateContainer(ctr) })
+```
+Use `redis:7-alpine`, port `6379/tcp`. If a TestMain is used instead, copy `modules/beachcomber/postgres_test.go` lines 29-54 (`testShort()` with `flag.Parse()`). Fast loop: miniredis.
+
+### `modules/surf/serve.go` (boot wiring)
+**Analog:** same file lines 51-59:
+```go
+bucket, err := publishUploads(ctx, app)
+if err != nil { return err }
+defer bucket.Close()
+r, err := BuildRouter(app, plugins)
+```
+Insert `cooler.Install` + `app.Publish[Store](...)` between `publishUploads` and `BuildRouter` (RESEARCH Pattern 1). `route:list` must not get this.
+
+### `modules/surf/router.go`
+**Analog:** `BuildRouter` lines 467-500:
+```go
+lim := NewFixedWindowLimiter(NewMemoryStore(2*time.Minute), trusted)
+r.limiter = lim
+if err := r.RegisterMiddlewareFactory("surf", "throttle", func(param string) pact.Middleware {
+	return lim.Middleware(param)
+}); err != nil { return nil, err }
+```
+Replace store with `app.Lookup[Store]()` fallback; register `cors` and `turnstile` factories the same way. Optional providers: type-assert like `BucketProvider` (lines 121-126) for `APIDocsProvider`. `Router.compile` must add `OPTIONS` routes for chains containing `cors:<p>` (Pitfall 5).
+
+### `modules/surf/cors.go`
+**Analog:** itself. Edit points: `pathScopedCORS` pattern compile loop silently `continue`s on bad regex (make `LoadCORSConfig` return error); `Vary` only when `value != "*"` (set on every dynamic answer incl. preflight via `writeOptions`); `corsAllowOrigin` returns `"*"` under `allowAny` (boot error with credentials). Profile config reuses `CORSConfig` with `cfg.LoadSection("http.cors_profiles.<name>", &out)` as in `LoadCORSConfig`. Keep `TestCORSOptionsMatchesLaravel` (`cors_coverage_test.go` 99-147) green.
+
+### `modules/surf/apidocs.go`
+**Analog:** `modules/surf/uploads.go` (`mountUploads` via `GroupRaw`, ~148-170, gated by `storage.uploads.serve`) for opt-in mounting; config gate `http.api_docs.enabled`. YAML via `goccy/go-yaml` `YAMLToJSON` then `json.Compact` at boot; HTML via `html/template`.
+
+### `modules/bouncer/cookie.go`
+**Analogs:** `modules/bouncer/refresh.go` lines 12-50 (function signatures the handler wraps: `Refresh(secret, tokenString, refreshTTL, bl, grace, issuerURL)`, `RefreshAudienceFor(ctx, users, ...)`); production-secure refusal from `modules/cabana/auth.go` 503-517:
+```go
+if strings.EqualFold(strings.TrimSpace(app.Config.Environment()), "production") {
+	return false, errors.New("cabana: backend.cookie_secure: false is not allowed in the production environment")
+}
+```
+Note bouncer imports nothing framework-side: `LoadCookieConfig` should take plain values (or a minimal interface) rather than `*compass.Config`/`*backpack.App`, or confirm compass is acceptable. Shape from RESEARCH Pattern 3.
+
+### `modules/bouncer/turnstile.go`
+**Analog:** outbound-POST hygiene from `site_cache.go` (`http.NewRequestWithContext`, `io.LimitReader`, `purgeTransportError` without URL). Factory registered in surf (`router.go`), not bouncer.
+
+### `modules/lagoon/attach/bucket.go`, `s3_on.go`, `s3_off.go`
+**Analog:** `bucket.go` lines 1-80. Blank-import style (lines 13-14) moves to the tagged file:
+```go
+_ "gocloud.dev/blob/fileblob"
+_ "gocloud.dev/blob/memblob"
+```
+Insert the `s3Enabled` guard in `OpenBucket` after `normalizeBucketURL` (default branch passes `s3://` unchanged). `public_url` stored next to `publicPathPrefix` with the same `prefixMu`/getter pattern (lines 17-35). Error messages keep the `attach:` prefix and `SUMMER_...` env hint style.
+
+### `modules/lagoon/attach/diskext.go` + `store.go`
+**Analog:** `store.go` lines 141-151:
+```go
+contentType := baseMediaType(http.DetectContentType(head))
+if contentType == "application/octet-stream" {
+	if byExt := baseMediaType(mime.TypeByExtension("." + ext)); byExt != "" { contentType = byExt }
+}
+...
+diskName, err := newDiskName(ext)
+```
+Change to `newDiskName(DiskExtension(contentType, ext))`. Regression test in `store_test.go` with widened `Limits.Extensions`.
+
+### `internal/build/manifest.go` / `build.go`
+**Analog:** `manifest.go` 40-103: parse via `asMap/asSlice/asString` from `tree`, validate, append; `SaveManifest` writes with `fmt.Fprintf(&b, ...)` lines. Add `build.tags` in both (round-trip test). `build.go` line 49:
+```go
+cmd := exec.CommandContext(ctx, "go", "build", "-o", binRel, ".")
+```
+insert `"-tags=" + strings.Join(tags, ",")` when non-empty.
+
+### `modules/pact/capabilities.go` + `modules/cabana/reorder.go`
+**Analog:** pact lines 748-765:
+```go
+// FormAfterDelete optionally runs after delete, inside the same transaction.
+type FormAfterDelete interface {
+	FormAfterDelete(ctx context.Context, model any) error
+}
+```
+Call site pattern from `crud.go` 1035-1039:
+```go
+if hook, ok := cc.Controller.(pact.FormAfterDelete); ok && hook != nil {
+	if err := lifecycleFailure(cc, hook.FormAfterDelete(ctx, model)); err != nil { return err }
+}
+```
+Place in `reorderPost` inside the `Transaction` closure after the node loop (reorder.go ~343), using `txCtx`. Check for in-flight cabana edits (phase 18.1).
+
+### Plugin adoption: `../sm-journal-plugin`
+- `plugin.go` `wireSiteCache` (lines 60-82): read framework keys first, else alias keys `classes.SiteCachePurgeURLKey`/`TokenKey` with `slog.Warn` deprecation; publish the cooler purger instead of `*classes.SiteCachePurger` (or have Install publish it and Journal only fill the alias case). Keep `classes` exported names as thin aliases/wrappers for one release (no breaking change).
+- `controllers/site_cache.go`: `Lookup[*cooler.SiteCachePurger]`.
+
+### `../sm-menu-plugin/controllers/menus.go`, `menuentries.go`, `../sm-faq-plugin/controllers/faqs.go`
+**Analog:** `../sm-journal-plugin/controllers/categories.go` lines 64-88:
+```go
+func (c categoriesAdminController) FormAfterCreate(ctx context.Context, model any) error {
+	return c.purgeAfterCommit(ctx, model)
+}
+func (c categoriesAdminController) purgeAfterCommit(ctx context.Context, model any) error {
+	cat, ok := model.(*models.Category)
+	...
+	purger, tx := siteCachePurger(ctx, c.app)
+	classes.PurgeSiteCacheAfterCommit(ctx, tx, purger, "category", cat.Slug)
+	return nil
+}
+```
+Caveat: faqs.go (lines 55-60) and menuentries.go (line 190+) already implement `FormAfterCreate/Update` for validation; append the purge call after the existing check rather than adding a second method. Add `FormAfterDelete` and the new reorder hook (menuentries). Controllers need an `app` accessor like Journal's `c.app` (menuentries has `registry()`/`pool()` helpers at 76-100 to model it on). Add compile-time asserts like faqs.go 73-74.
+
+### `../vue-*-layer/server/api/__site__/cache/purge.post.ts`
+**Analog:** `../vue-journal-layer/server/api/__journal__/cache/purge.post.ts` (whole file) and `app/utils/siteCache.ts` (`authorizePurge`, `parsePurgeEvent`, `purgeRouteCache`). Copy into each layer with `config.siteCache.purgeToken`; menu/faq layers need their own copy of the util (they have only `server/plugins/*-client-address.ts` today). Journal layer keeps the old route as alias.
+
+### `../vue-*-layer/nuxt.config.ts`
+**Analog:** `../vue-journal-layer/nuxt.config.ts` lines 27-51:
+```ts
+runtimeConfig: { journal: { apiBase: ..., cachePurgeToken: '' } },
+routeRules: { '/api/__journal__/**': { cache: false } },
+```
+Add `siteCache: { purgeToken: '' }` and `'/api/__site__/**': { cache: false }` to all three.
+
+## Shared Patterns
+
+### Publish/lookup services on the app
+**Source:** `modules/postcard/mailer.go` 100; `../sm-journal-plugin/controllers/site_cache.go` 24
+`app.Publish[Iface](impl)` at boot; consumers `a.Lookup[T]()` with `ok && v != nil` check; nil service means disabled.
+
+### Named middleware factories
+**Source:** `modules/surf/router.go` 118-123, 478-482. Apply to `cors:<profile>`, `turnstile:open|closed`.
+
+### Production-only refusals
+**Source:** `modules/cabana/auth.go` 503-517 (`app.Config.Environment() == "production"`). Apply to cookie `secure: false`, Turnstile unconfigured closed mode.
+
+### Secret-safe errors and logs
+**Source:** `site_cache.go` `purgeTransportError` and "error names the key, never the token". Apply to redis.url, Turnstile secret, purge token.
+
+### Docker-gated tests
+**Source:** `modules/beachcomber/postgres_test.go` 29-54, `modules/postcard/mailpit_test.go` 35-60.

+# Phase 19.3: Framework transport and infrastructure for WavePath - Research
+
+**Researched:** 2026-10-15
+**Domain:** Go HTTP transport (cookies, CORS), Redis cache and distributed rate limiting, gocloud blob/S3, OpenAPI page, Cloudflare Turnstile, cross-repo site-cache purge
+**Confidence:** HIGH for the in-repo seams and dependency versions; MEDIUM for the S3-compatible-provider and Nuxt-layer details
+
+<user_constraints>
+## User Constraints (from CONTEXT.md)
+
+### Locked Decisions
+
+#### Cookie transport (bouncer)
+- **D-01:** `bouncer` ships config-driven cookie builders (`TokenCookie` and `ForgetTokenCookie` or similar) and an optional ready-made cookie refresh/logout handler. The handler reads the token cookie, calls the existing `Refresh*` path (which already rotates the token and blacklists the old JTI) and sets the rotated cookie. The app supplies a writer func so it keeps its own response envelope. The shared `sm-user-plugin` is NOT changed to set cookies; apps opt in.
+- **D-02:** Cookie attributes live in one framework block, `auth.cookie.*`: `name`, `domain`, `secure`, `same_site`, `path`. Cookie Max-Age comes from the guard's `refresh_ttl`, not its `ttl`: the cookie must outlive the access token, or refresh has no cookie to read (PHP comment in `AuthApiController::tokenCookie`). The existing per-guard `ttl`/`refresh_ttl` keys (`golem15.user.jwt.*`, `admin.jwt.*`) stay where they are. — **Reversibility:** costly — apps' config files and deploy docs reference these keys once they ship.
+- **D-03:** Defaults when unset match PHP: name `token`, path `/`, httpOnly, `SameSite=Lax`, no Domain (host-only), Secure when the app URL is https, Max-Age = refresh window (20160 min default).
+
+#### Credentialed CORS (surf)
+- **D-04:** Harden the existing path-scoped `http.cors` (`surf.CORSConfig.SupportsCredentials`):
+  - Refuse, or at least loudly reject at boot, credentials combined with a `*` origin.
+  - Always echo the exact origin, and set `Vary: Origin` on preflight too.
+  - Test the api ↔ www subdomain case.
+- **D-05:** Also add a named CORS middleware (for example `cors:<profile>`) so a route group can carry its own CORS policy on top of the global path-scoped one.
+
+#### Cache and rate-limit store (new module `cooler`)
+- **D-06:** New module **`cooler`** for the cache. The name comes from the research: `.planning/research/ARCHITECTURE.md` lists `cooler` for "in-process cache, rate-limit buckets", and `IDEA_LIB_NAMES.md` has `summer-cooler`. It gets a beach-name README and a row in the root table.
+- **D-07:** Redis client is **go-redis v9** (`github.com/redis/go-redis/v9`). A decision note under `.planning/notes/` names it before code lands. The memory driver is otter v2 (research/go-ecosystem.md) or a stdlib map; the researcher picks one and the note records it. — **Reversibility:** costly — every Redis-touching module and app config builds on this client.
+- **D-08:** The cache API is a Laravel-core subset: Get, Set, Has, Forget, Remember, Increment and Flush, with TTL and a per-app key prefix. No tags. An atomic lock only if a 19.x port is shown to need it.
+- **D-09:** Selection uses one shared Redis block, `redis.url`, plus `cache.driver: memory|redis` and `http.rate_limit.store: memory|redis`. The framework wires everything at boot, so apps import nothing. `cooler` implements `surf.Store` for Redis (an atomic fixed-window script with the same semantics as `surf.MemoryStore`), so `surf` takes no Redis dependency.
+
+#### Site-cache purge (folded todo, in `cooler`)
+- **D-10:** A framework purge service in `cooler`:
+  - One configured target: `site_cache.purge_url` and `site_cache.purge_token`.
+  - A loopback POST with a bearer token, sent after a committed admin save.
+  - Failures are logged and never fail the save.
+- **D-11:** Plugin adoption is in this phase:
+  - Journal moves onto the service. Its current `golem15.journal.site_cache.*` keys stay as aliases for one release.
+  - The menu plugin purges after a menu or menu-entry save, reorder or delete. The FAQ plugin purges after a FAQ save or delete.
+  - The Nuxt purge route moves out of `vue-journal-layer` to a shared place, so a site without Journal still gets purges.
+  - Plugin repos are committed and pushed first; pointer bumps in apps are separate commits.
+  - Core plugins must not break: the alias keys keep existing Journal deployments working.
+
+#### S3 and uploads (lagoon/attach)
+- **D-12:** New key `storage.uploads.public_url`. When set (a bucket or CDN base), `File` URLs are that base plus the partition path. When unset, files go through the existing `/storage/uploads` proxy route, which works for S3 too.
+- **D-13:** The S3 driver (`gocloud.dev/blob/s3blob`) is opt-in through a **build tag**. `summer build` sets the tag from `summer.yaml`, so an app still never imports the driver itself. A `bucket_url: s3://…` in a binary built without the tag must fail at boot with an error that names the tag.
+- **D-14:** S3-compatible endpoints (MinIO, R2, Hetzner) are configured through gocloud's native `bucket_url` query (`region`, `endpoint`, `use_path_style`). Credentials come from the standard AWS env vars. No parallel `s3.*` key set.
+- **D-15:** Folded stored-XSS fix: `attach.Store` takes the disk-name extension from the sniffed MIME type, through one shared helper. The client name stays only in `file_name`. A regression test checks that a PNG uploaded as `x.html` gets a `.png` disk name and URL. The deploy docs gain a note on nosniff and a file-type allow-list. App call sites (fonoteka `storeUpload`/`StorePublicFile`) move to the helper in a follow-up, not in this phase.
+
+#### API docs (surf)
+- **D-16:** The spec is supplied by an app or plugin: an embedded YAML or JSON file, converted to JSON once and cached. This matches PHP, which serves a hand-written YAML covering only the public surface. Nothing is generated from swag here.
+- **D-17:** Routes are opt-in through config (`http.api_docs.enabled` plus the path), off by default. `/api-docs` serves a Swagger UI page from pinned jsDelivr `swagger-ui-dist@5` with SRI, like PHP. `/api-docs.json` serves the spec. Both are public and unauthenticated.
+
+#### Turnstile (bouncer)
+- **D-18:** `bouncer` gets a Turnstile verifier, `Verify(ctx, token, ip, failClosed)`, with a 5 s timeout, plus a named middleware factory such as `turnstile:open|closed`. Semantics follow PHP `TurnstileVerifier`:
+  - Fail-open: an empty secret passes (dev no-op, the registration path).
+  - Fail-closed: 503 when unconfigured in production, 422 on a missing token, a siteverify false, an exception or a timeout (the guest entry path).
+  - Error bodies come from a writer func, so the app keeps the PHP shape. The secret is read from config, which maps the `TURNSTILE_*` env.
+
+#### Module placement
+- **D-19:** `cooler` holds the cache, the Redis `surf.Store` adapter and the site-cache purge. `surf` holds `/api-docs` and the named CORS middleware. `bouncer` holds the cookie helpers and handler, and Turnstile. `lagoon/attach` holds the S3 tag, `public_url` and the extension fix.
+
+### Claude's Discretion
+- The exact Go identifiers, the handler signatures and the name of the named-CORS-middleware profile config.
+- otter vs a stdlib map for the memory cache driver (recorded in the decision note).
+- Whether the token cookie builder lives on a guard or as free functions.
+- The exact build-tag name and how `summer.yaml` declares it.
+
+### Deferred Ideas (OUT OF SCOPE)
+- Switching fonoteka.go's `storeUpload`/`StorePublicFile` to the new extension helper: a follow-up quick task in fonoteka.go.
+- Cache tags and atomic locks: add them only when a ported plugin needs them.
+- Generating `/api-docs` specs from swag annotations for frontend routes: later, if wanted.
+- A Redis-backed `bouncer.BlacklistStore`: optional, not required by the criteria.
+
+Reviewed todos not folded: the WinterCMS-vs-SummerCMS benchmark, and porting the FAQ plugin (already its own repo).

+| D-15 | Disk-name extension from the sniffed type | §Extension helper (DetectContentType probe), Pitfall 8 |
+</phase_requirements>
+
+## Project Constraints (from CLAUDE.md)
+
+- One Go module `git.golem15.com/golem15/summercms`; a new module (`cooler`) gets a beach name, a README in the standard structure (H1, one-sentence summary, import line, `**Name:**` mnemonic, Overview, Features, Usage, API reference, optional Configuration/CLI, Dependencies, Testing) and a row in the root `README.md` table whose purpose text reuses the summary sentence.
+- **A new dependency needs a research doc or a decision note naming it** (`.planning/research/STACK.md` holds the decided set). go-redis, otter and (test-only) miniredis each need to be named in a note before code lands. `gocloud.dev/blob/s3blob` is a sub-package of the already-required `gocloud.dev v0.46.0`, but it pulls the AWS SDK v2 into `go.sum`; name it in the same note.
+- YAML is parsed with `goccy/go-yaml`, never `gopkg.in/yaml.v3`.
+- Standard library first.
+- A change to a module's exported API, config keys, CLI commands or dependencies updates that module's README and the affected `docs/` pages **in the same commit**. Every identifier in a README or docs page must exist in the package (the docs checker enforces it); config keys are reviewed by hand.
+- Framework code never names a consuming application (READMEs, docs, examples use neutral names such as `blog` or `acme`). The docs checker's forbidden pattern covers only two names (see §Docs checker); "WavePath" is not covered, so review by hand.
+- Keep `go vet ./...` and `go test ./...` green at every commit. Docker tests skip under `-short`; a `TestMain` that starts containers calls `flag.Parse()` and checks `testing.Short()`.
+- Lean planning: few, large plans. Present the plan count with one-line scopes and wait for confirmation before writing PLAN.md files.
+- **Unit tests are the last plan of the phase.** Earlier plans may carry smoke tests.
+- STATE.md updates go through `msd_run query state.*` handlers; g15office gets a comment when the phase advances.
+- No co-author tags; one logical change per commit; planning docs and code in separate commits; stage files by explicit path; check for other sessions' in-flight edits before touching shared files such as cabana (phase 18.1 is executing in parallel).
+- Sibling plugin repos: commit and push the plugin first, then the pointer bump in the app as a separate commit. Never stage files inside a submodule from the app repo. Don't push, tag or deploy without the user's go-ahead.
+- User global rule: core plugins (user, blog/journal, pages, payment) must not get breaking changes unless asked. This is why D-11 keeps the Journal alias keys.
+
+## Summary
+
+Every piece of this phase lands on an existing, well-defined seam, so most of the research is about wiring rather than new technology. `surf.Store` is a three-value interface with no context and no error (`Attempt(key string, max int, decay time.Duration) (allowed bool, attempts int, retryAfter time.Duration)`), so a Redis implementation in `cooler` satisfies it structurally without importing `surf`. That lets `surf` import `cooler` (not the reverse) and keeps the dependency graph acyclic. The fixed-window Lua script below was run against the local Redis 7.2.5 and reproduces `MemoryStore` exactly: the first attempt opens the window, a denied attempt does not increment, and the window never extends.
+
+The biggest traps are not in the libraries. First, `surf.BuildRouter` hard-codes `NewMemoryStore` and is also called by `route:list`, so the Redis store must be published before `serve` builds the router, and `route:list` must never dial Redis. Second, `cabana`'s reorder POST runs no controller hook today, so "menu purges after reorder" (D-11) needs a new optional `pact` hook. Third, route-level `cors:<profile>` middleware never sees a preflight, because the stdlib ServeMux answers `OPTIONS` on a `GET`-only pattern with 405 before any middleware runs; the router has to register `OPTIONS` routes for profiled routes. Fourth, every app's `scripts/build.sh` runs `summer build` and then a second, raw `go build` for linux/amd64, which drops any tag `summer build` set. The D-13 boot error is what catches that.
+
+PHP parity notes that change the plan: the PHP `/api-docs` page does **not** use SRI and loads the floating `swagger-ui-dist@5`, so "with SRI, like PHP" requires pinning an exact version (5.33.1 is recommended; the hashes are below). PHP's php-cors v1.4.0 reflects **any** origin when `*` is combined with credentials, which is exactly what D-04 forbids, so Go diverges from PHP deliberately. Turnstile's PHP "fail-open" mode only skips verification when the secret is empty. With a secret set, both modes reject a `success:false`.
+
+**Primary recommendation:** Build `cooler` first (decision note, then the cache with an otter v2 memory driver, the go-redis v9.23.0 driver, the Redis `surf.Store` and the `serve`-time wiring via `app.Lookup[surf.Store]`). Then the transport pieces in `bouncer` and `surf`, the attach S3/extension work, and the purge adoption across repos, with unit tests as the last plan.

+## Architectural Responsibility Map
+
+| Capability | Primary Tier | Secondary Tier | Rationale |
+|------------|-------------|----------------|-----------|
+| Token cookie build/clear, refresh/logout handler | API / Backend (`bouncer`) | Browser (cookie jar) | Cookie attributes are server-decided; the handler wraps `bouncer.Refresh*` |
+| Credentialed CORS (global + profiles) | API / Backend (`surf`) | Browser (enforces) | Outermost HTTP wrapper; preflights answered before routing |
+| Cache (memory/Redis) | API / Backend (`cooler`) | Database/Storage (Redis) | Shared state for multi-instance apps |
+| Distributed rate limit | API / Backend (`surf` limiter) | Database/Storage (Redis via `cooler`) | `surf` keeps the policy; `cooler` owns the atomic counter |
+| Site-cache purge | API / Backend (`cooler` service, plugin hooks) | Frontend Server (Nuxt/Nitro purge route) | After-commit POST from Go to the SSR server on loopback |
+| S3 uploads, `public_url` | Database/Storage (`lagoon/attach`, bucket) | CDN / Static | Bucket choice is boot config; URL base may be a CDN |
+| Disk-name extension (XSS) | API / Backend (`attach.Store`) | CDN / Static (nginx type mapping) | The extension decides the Content-Type a static server sends |
+| `/api-docs` page and JSON | API / Backend (`surf`) | CDN (jsDelivr assets with SRI) | Server renders the shell; the browser loads pinned assets |
+| Turnstile verification | API / Backend (`bouncer` verifier, `surf` factory) | External (Cloudflare siteverify) | Secret never leaves the server |

+|---------|---------|---------|-------------|
+| `github.com/alicebob/miniredis/v2` | v2.40.0 (2026-10-10) [VERIFIED: proxy.golang.org]; name from training [ASSUMED provenance] | In-process Redis for `-short` unit tests | Supports EVAL/EVALSHA/SCRIPT LOAD, PTTL, SET, INCR/INCRBY, SCAN, UNLINK, and `FastForward` for TTLs [VERIFIED: miniredis@v2.40.0/README.md:47-95,221-225,253]; one dep (`gopher-lua`) |
+| `github.com/testcontainers/testcontainers-go` | v0.44.0 (already required) | Docker-gated real-Redis test | Use the generic `testcontainers.Run(ctx, "redis:7-alpine", …)` as `modules/postcard/mailpit_test.go:47-58` does. No `modules/redis` sub-module is needed |
+
+### Alternatives Considered
+| Instead of | Could Use | Tradeoff |
+|------------|-----------|----------|
+| otter v2 | stdlib `map` + mutex + sweeper | ~100 lines, no dependency, but **unbounded**: a key-per-client cache (`Remember("user:"+id)`) grows forever; adding LRU bounds is a hand-rolled cache. otter gives a size bound (`MaximumSize`), per-entry TTL (`ExpiryCalculator`), atomic `Compute` for Increment and an injectable `Clock` for tests, with no runtime dependencies (go.mod requires only testify, for its own tests) [VERIFIED: otter@v2.3.0 go.mod, options.go:71-154, cache.go:157-224] |
+| miniredis for unit tests | testcontainers Redis only | Real Redis is authoritative but needs Docker (skipped under `-short`); use both: miniredis for the fast loop, one Docker test that runs the same script on real Redis |
+| Build tag for S3 (locked) | Generated blank import in `plugins.gen.go` | A generated import survives the apps' second raw `go build`; a tag does not (Pitfall 6). D-13 locks the tag, so keep the boot-time error as the safety net |
+
+**Installation (framework module):**
+```bash
+go get github.com/redis/go-redis/v9@v9.23.0 github.com/maypok86/otter/v2@v2.3.0
+go get github.com/alicebob/miniredis/v2@v2.40.0   # test-only, after its decision note
+go mod tidy   # also pulls aws-sdk-go-v2 into go.sum once the tagged s3blob import exists
+```
+
+**Memory-driver recommendation for the decision note (D-07 discretion): otter v2.** Reasons: bounded memory (DoS-safe when keys derive from request data), per-entry TTL including "forever" (otter's docs: "To indicate no expiration, an entry may be given an excessively long period" [VERIFIED: otter@v2.3.0/expiry_calculator.go:23-37]), lock-scoped `Compute` for an atomic Increment, a testable `Clock`, and the framework's own architecture research already names it.

+## Package Legitimacy Audit
+
+The `package-legitimacy` seam supports npm/pypi/crates only; Go modules were checked against proxy.golang.org (existence, publish time, VCS origin).

+
+**Packages removed due to [SLOP] verdict:** none. (The seam reports `SLOP` for `swagger-ui-dist@5.33.1` only because it treats `name@version` as a package name; the package-level check is `SUS: too-new`, which applies to the 3-day-old latest.)
+**Packages flagged as suspicious [SUS]:** swagger-ui-dist latest (5.33.2). Avoided by pinning 5.33.1.

+```
+
+### Pattern 1: Boot wiring without an import cycle
+**What:** `cooler` implements `surf.Store` structurally; `surf` imports `cooler`; `serve` publishes the store under the interface type before `BuildRouter`.
+**Evidence:** `surf.Store` [VERIFIED: modules/surf/limiter_store.go:11-13]:
+```go
+type Store interface {
+	Attempt(key string, max int, decay time.Duration) (allowed bool, attempts int, retryAfter time.Duration)
+}
+```
+`BuildRouter` today [VERIFIED: modules/surf/router.go:475-477]:
+```go
+	// longest bucket decay is 1 minute; sweep at 2x
+	lim := NewFixedWindowLimiter(NewMemoryStore(2*time.Minute), trusted)
+	r.limiter = lim
+```
+`app.Publish[T]` keys the registry by `reflect.TypeFor[T]()` [VERIFIED: modules/backpack/services.go:22-48], so the store must be published as `app.Publish[surf.Store](…)`, which only `surf` (or `main`) can write. Import graph today: `lagoon` depends on compass, festival, backpack, bonfire, lagoon/attach, pact, towel, phrasebook, postcard, signpost and party (not surf), and `bouncer` depends on nothing in the framework [VERIFIED: `go list -deps`], so `surf → cooler → {lagoon, compass, backpack, go-redis}` is acyclic.
+**Example:**
+```go
+// modules/surf/serve.go, inside ServeCommand Run, after publishUploads:
+c, err := cooler.Install(ctx, app) // parses redis.url, pings when a redis driver is selected, publishes cooler.Cache
+if err != nil { return err }
+defer c.Close()
+if c.RateLimitRedis() {             // http.rate_limit.store == "redis"
+	if err := app.Publish[Store](c.RateLimitStore(NewMemoryStore(2 * time.Minute))); err != nil { return err }
+}
+r, err := BuildRouter(app, plugins)
+
+// modules/surf/router.go, BuildRouter:
+var store Store
+if app != nil {
+	if s, ok := app.Lookup[Store](); ok && s != nil { store = s }
+}
+if store == nil { store = NewMemoryStore(2 * time.Minute) }
+lim := NewFixedWindowLimiter(store, trusted)
+```
+`route:list` calls only `BuildRouter`, so it keeps the memory store and never touches Redis. Note `conga`'s dedicated worker command does not go through `serve`; a job that needs the cache should call `cooler.FromApp(app)`, which constructs lazily (go-redis `NewClient` does not dial until the first command).
+
+### Pattern 2: Redis fixed-window script with MemoryStore semantics
+**Semantics to match** [VERIFIED: modules/surf/limiter_store.go:68-93]: an expired or missing entry resets to `count: 0, resetAt: now.Add(decay)`; `retryAfter = resetAt - now` (floored at 0); `if e.count >= max { return false, e.count, retryAfter }`; otherwise `e.count++` and allow. Expiry is lazy and the window never extends.
+
+```lua
+-- KEYS[1] = <prefix>rl:<bucket key>; ARGV[1] = max; ARGV[2] = decay in ms (>= 1)
+local max = tonumber(ARGV[1])
+local decay = tonumber(ARGV[2])
+local count = tonumber(redis.call('GET', KEYS[1]) or '0')
+local ttl = redis.call('PTTL', KEYS[1])
+if ttl < 0 then            -- -2 missing, -1 no expiry: open a fresh window
+  count = 0
+  redis.call('SET', KEYS[1], 0, 'PX', decay)
+  ttl = decay
+end
+if count >= max then
+  return {0, count, ttl}   -- denied: count unchanged
+end
+count = redis.call('INCR', KEYS[1])   -- INCR keeps the TTL
+return {1, count, ttl}
+```
+Probe on the local Redis 7.2.5 with max=3, decay=2000 ms [VERIFIED: redis-cli --eval, this session]:
+```
+1 1 2000
+1 2 1957
+1 3 1952
+0 3 1945      <- denied, count stays 3
+TTL=1939 GET=3
+1 1 2000      <- after 2.1 s: new window
+```
+Go side: `var attemptScript = redis.NewScript(src)`; `res, err := attemptScript.Run(ctx, client, []string{key}, max, ms).Int64Slice()` (EVALSHA with EVAL fallback) [VERIFIED: go-redis@v9.23.0/script.go:34,193 and command.go:887]. Use `context.WithTimeout(context.Background(), ~500ms)` because `Attempt` has no ctx. Clamp `decay.Milliseconds()` to at least 1, or `SET PX 0` errors. Redis uses its own clock, so instance clock skew does not matter.
+
+### Pattern 3: Cookie transport in bouncer (D-01..D-03)
+PHP reference [VERIFIED: wavepath.org …/AuthApiController.php:342-381]: `cookie(self::COOKIE_NAME, $token, $minutes = config('jwt.refresh_ttl', 20160), '/', domain, secure, true /*httpOnly*/, false, 'lax')`; forget = the same attributes, empty value and far-past expiry. Domain is `WAVEPATH_COOKIE_DOMAIN` or null; Secure is true in production or on a secure request [VERIFIED: …/CookieAttributes.php]. The `token` cookie is **unencrypted** (`config/cookie.php` `unencryptedCookies` lists `'token'`) [VERIFIED: wavepath.org config/cookie.php:17-22], so Go can read cookies the PHP app issued. User-plugin defaults: `ttl: 60`, `refresh_ttl: 20160`, `blacklist_grace: 0` [VERIFIED: fonoteka.go/plugins/golem15/user/config/config.yaml].
+```go
+// bouncer/cookie.go (identifiers are Claude's discretion)
+type CookieConfig struct {
+	Name     string        // auth.cookie.name, default "token"
+	Domain   string        // auth.cookie.domain, default "" (host-only)
+	Path     string        // auth.cookie.path, default "/"
+	Secure   bool          // auth.cookie.secure, default: app.url scheme == https
+	SameSite http.SameSite // auth.cookie.same_site: lax|strict|none, default lax
+}
+func (c CookieConfig) TokenCookie(token string, refreshTTL time.Duration) *http.Cookie {
+	return &http.Cookie{Name: c.Name, Value: token, Path: c.Path, Domain: c.Domain,
+		MaxAge: int(refreshTTL / time.Second), Expires: time.Now().Add(refreshTTL),
+		HttpOnly: true, Secure: c.Secure, SameSite: c.SameSite}
+}
+func (c CookieConfig) ForgetTokenCookie() *http.Cookie { /* same attrs, Value "", MaxAge -1, Expires Unix(0) */ }
+
+// Handler: app supplies Refresh (choose Refresh / RefreshAudienceFor) and the envelope writer.
+type CookieRefreshOptions struct {
+	Cookie     CookieConfig
+	RefreshTTL time.Duration
+	Refresh    func(ctx context.Context, token string) (string, error)
+	Write      func(w http.ResponseWriter, r *http.Request, status int, err error)
+}
+```
+Validate at boot with `(*http.Cookie).Valid()`, which rejects an invalid Domain [VERIFIED: GOROOT net/http/cookie.go:349-353]. Reject `same_site: none` without Secure, and refuse `secure: false` in production, mirroring `adminCookieSecure` [VERIFIED: modules/cabana/auth.go:503-517]. Production is `app.Config.Environment() == "production"` (`SUMMER_ENV`) [VERIFIED: modules/compass/config.go:75-83].
+
+### Pattern 4: CORS hardening (D-04) and profiles (D-05)
+Current keys [VERIFIED: modules/surf/cors.go:13-22]: `paths`, `allowed_methods`, `allowed_origins`, `allowed_origins_patterns`, `allowed_headers`, `exposed_headers`, `max_age`, `supports_credentials`. Today `corsAllowOrigin` returns `"*"` when any origin is allowed, even with credentials [VERIFIED: cors.go:134-137]; `Vary: Origin` is only set when an origin is allowed and the value is not `*` [cors.go:71-75]; invalid `allowed_origins_patterns` are silently skipped [cors.go:44-51]; and wildcard entries in `allowed_origins` such as `https://*.example.com` are treated as literals. php-cors v1.4.0 converts them to patterns [VERIFIED: wavepath vendor/fruitcake/php-cors/src/CorsService.php:100-131].
+
+PHP behaviour [VERIFIED: CorsService.php:204-220]: `*` without credentials sends `*`; a single listed origin sends that origin unconditionally; otherwise it echoes an allowed origin and **always** adds `Vary: Origin`; `*` **with** credentials reflects every origin. Recommended Go rules:
+1. Boot error: `supports_credentials: true` with `*` in `allowed_origins` (global and every profile).
+2. Boot error: an `allowed_origins_patterns` entry that does not compile. Also error on a PHP-delimited pattern such as `#^https://…$#`, since Go would compile it as literal `#` characters.
+3. Translate `*` inside an `allowed_origins` entry into an anchored pattern (php-cors `convertWildcardToPattern`).
+4. When the answer is dynamic (credentials, patterns or more than one origin), add `Vary: Origin` to **every** response on a CORS path, preflight and disallowed origin included. Keep the current `*` non-credentialed behaviour byte-identical: all four apps run `allowed_origins: ["*"]` without credentials, and `TestCORSOptionsMatchesLaravel` pins the preflight headers [VERIFIED: modules/surf/cors_coverage_test.go:99-147].
+
+Profiles: config `http.cors_profiles.<name>` with the `CORSConfig` keys minus `paths`. Factory `cors` registered in `BuildRouter` like `throttle`. Because `ServeMux` answers `OPTIONS` on a `GET`/`POST` pattern with 405 before route middleware, `Router.compile` must register `OPTIONS <path>` for every route whose chain contains `cors:<p>`, with a handler that answers the preflight from the profile. Boot error when such a route's path also matches the global `http.cors.paths` (the global wrapper would answer the preflight first).
+
+### Pattern 5: S3 build tag (D-13/D-14)
+```go
+// modules/lagoon/attach/s3_on.go
+//go:build summercms_s3
+package attach
+import _ "gocloud.dev/blob/s3blob"
+const s3Enabled = true
+
+// modules/lagoon/attach/s3_off.go
+//go:build !summercms_s3
+package attach
+const s3Enabled = false
+
+// in OpenBucket, before blob.OpenBucket:
+if strings.EqualFold(u.Scheme, "s3") && !s3Enabled {
+	return nil, fmt.Errorf("attach: storage.uploads.bucket_url uses s3:// but this binary was built without the summercms_s3 build tag; add it under build.tags in summer.yaml and rebuild (raw go build needs -tags summercms_s3)")
+}
+```
+`normalizeBucketURL` already passes unknown schemes through unchanged (`default: return raw, nil`) [VERIFIED: modules/lagoon/attach/bucket.go:42-57]. `summer build` runs `exec.CommandContext(ctx, "go", "build", "-o", binRel, ".")` [VERIFIED: internal/build/build.go:49]; add `-tags=<joined>` from the manifest. Recommended `summer.yaml` shape (discretion):
+```yaml
+build:
+  tags:
+    - summercms_s3
+```
+Validate each tag against `^[a-z0-9_]+$`. `SaveManifest` (used by `plugin:add`) rewrites only `module`, `binary` and `plugins` [VERIFIED: internal/build/manifest.go:90-103], so it **must** round-trip `build.tags` or `summer plugin:add` silently drops S3. `dev` watch reuses `build.App` [VERIFIED: internal/dev/watch.go:45-46], so it inherits the tags.
+
+S3 URL query (gocloud v0.46.0) [VERIFIED: gocloud.dev@v0.46.0/blob/s3blob/s3blob.go:118-136, aws/aws.go:70-180]: s3blob-specific `ssetype`, `kmskeyid`, `accelerate`, `use_path_style` (legacy `s3ForcePathStyle`) and `disable_https`; AWS config `region`, `endpoint`, `hostname_immutable`, `profile`, `role`, `anonymous`, `dualstack`, `fips`, `rate_limiter_capacity`, `request_checksum_calculation`, `response_checksum_validation` (`when_supported|when_required`). Unknown params are an error. Example for an S3-compatible endpoint:
+```
+s3://uploads?region=auto&endpoint=https://<account>.r2.cloudflarestorage.com&use_path_style=true&request_checksum_calculation=when_required&response_checksum_validation=when_required
+```
+
+### Pattern 6: Disk-name extension helper (D-15)
+`Store` derives the disk name from the client extension: `diskName, err := newDiskName(ext)` [VERIFIED: modules/lagoon/attach/store.go:151] after sniffing `contentType := baseMediaType(http.DetectContentType(head))` [store.go:141]. The defaults already reject `x.html` (`DefaultFileExtensions` has no html, svg or xml [store.go:54-59]), so the regression test must widen `Limits.Extensions` (for example `[]string{"html", "png"}`). DetectContentType probe (Go 1.27) [VERIFIED: go run, this session]: png→`image/png`, docx/zip→`application/zip`, mkv→`video/webm`, mp3(ID3)→`audio/mpeg`, txt/ics/svg/`hello <script>`→`text/plain; charset=utf-8`, `<html>`→`text/html; charset=utf-8`, `<?xml`→`text/xml`, pdf→`application/pdf`, woff2→`font/woff2`, rar→`application/x-rar-compressed`, avif and short mp4 and OLE .doc→`application/octet-stream`. `mime.ExtensionsByType("image/jpeg")` returned `[.jfif .jpe .jpeg .jpg .pjp .pjpeg]` on this host: host-dependent, so do not use it.
+
+Recommended rule:
+```go
+// DiskExtension picks the stored extension. clientExt is already lower-cased and allow-listed.
+// 1. A specific sniffed type (table: image/png→png, image/jpeg→{jpg,jpeg}, image/gif, image/webp,
+//    application/pdf, audio/mpeg→mp3, video/webm→{webm,mkv}, font/woff2, application/x-rar-compressed→rar, …):
+//    keep clientExt when it belongs to that type's set, else the type's canonical extension.
+// 2. A generic sniff (application/octet-stream, application/zip, text/plain, text/html, text/xml):
+//    keep clientExt unless it is script-capable (html, htm, xhtml, xht, shtml, svg, svgz, xml, xsl,
+//    xslt, js, mjs, css, swf, php, phtml): then "txt" for text/*, "bin" otherwise.
+func DiskExtension(contentType, clientExt string) string
+```
+The allow-list check stays on the client extension, so accepted uploads do not change; only the stored name and URL change for mismatched uploads, as the todo expects.
+
+### Pattern 7: Turnstile (D-18)
+PHP [VERIFIED: wavepath.org …/TurnstileVerifier.php]: siteverify `https://challenges.cloudflare.com/turnstile/v0/siteverify`, form fields `secret`, `response`, `remoteip`. **Open mode:** an empty secret returns true; otherwise POST (no explicit timeout, exceptions not caught) and return `json('success') ?? false`. **Closed mode:** an empty secret returns `app.env !== 'production'`; an empty token returns false; POST with `timeout(5)` and `success === true`; any exception returns false. Controllers check `isConfiguredForGuests()` first and answer 503 `guest_unavailable`, then 422 `captcha_failed`; registration answers 422 `TURNSTILE_FAILED` [VERIFIED: GuestCallController.php:62-70, AuthApiController.php:68-72,182-189]. The token comes from the request field `turnstile_token` (`$request->get`). Cloudflare [CITED: developers.cloudflare.com/turnstile/get-started/server-side-validation/]: form or JSON accepted; tokens are at most 2048 chars, valid for 300 s and single-use (`timeout-or-duplicate`); optional `idempotency_key`. Test secrets [CITED: developers.cloudflare.com/turnstile/troubleshooting/testing/]: `1x0000000000000000000000000000000AA` passes, `2x0000000000000000000000000000000AA` fails, `3x0000000000000000000000000000000AA` returns timeout-or-duplicate, each with the dummy token `XXXX.DUMMY.TOKEN.XXXX`.

+Design: `bouncer.Turnstile{Secret, Production bool, Endpoint (test override), Client *http.Client{Timeout: 5s}}` with `Verify(ctx, token, ip string, failClosed bool) (Verdict, error)`, so the middleware can tell "unconfigured" (503) from "failed" (422). Register the `turnstile` factory in `surf.BuildRouter` (it has `ClientIP` and trusted proxies; `bouncer` cannot import `surf`). The writer comes from `app.Lookup[bouncer.TurnstileWriter]()` with a neutral default JSON body. Config: `turnstile.secret` (env `SUMMER_TURNSTILE__SECRET`), optional `turnstile.field` (default `turnstile_token`). The middleware reads the field from a JSON or form body and **restores `r.Body`** (the body cap is already applied outside named middleware [VERIFIED: modules/surf/router.go:442-445]).
+
+### Pattern 8: Site-cache purge (D-10/D-11)
+Move `SiteCachePurger` from `sm-journal-plugin/classes/site_cache.go` into `cooler` nearly verbatim: URL/token validation (http only to loopback; token ≥ `SiteCachePurgeMinTokenLength = 32`), `SiteCachePurgeTimeout = 2 * time.Second`, `context.WithoutCancel`, a 4 KiB answer read, no token in logs, and `PurgeSiteCacheAfterCommit` via `lagoon.AfterCommit` [VERIFIED: sm-journal-plugin/classes/site_cache.go:21-48,114-184]. Framework keys `site_cache.purge_url` / `site_cache.purge_token`. Journal alias: in its `Register`, when the framework keys are unset and `golem15.journal.site_cache.purge_url`/`purge_token` are set [site_cache.go:24,27], build the cooler purger from the alias keys and log a deprecation warning. The framework never names the plugin's keys. Hooks: Journal already purges in `FormAfterCreate/Update/Delete` [VERIFIED: sm-journal-plugin/controllers/categories.go:64-88]; FAQ and menu add them. **Reorder has no hook** (Pitfall 9). Coalesce bursts (bulk delete of N rows means N after-commit purges) with a per-purger trailing debounce or an in-flight flag. (Superseded: the user chose no debounce, one POST per committed save; see Open Questions Q4.)
+
+Nuxt side: Nitro dedupes scanned handlers by route+method+env and keeps the first [VERIFIED: vue-journal-layer node_modules nitropack@2.13.4 dist/core/index.mjs:894-901]. So the shared place can be **the same route file in each of vue-journal-layer, vue-menu-layer and vue-faq-layer** (`server/api/__site__/cache/purge.post.ts`, runtimeConfig `siteCache.purgeToken`, env `NUXT_SITE_CACHE_PURGE_TOKEN`), with no new repo needed. The Journal layer keeps `/api/__journal__/cache/purge` and `journal.cachePurgeToken` as aliases for one release. Each layer needs `routeRules: { '/api/__site__/**': { cache: false } }` (Pitfall 10). Sites consume layers as pnpm git deps pinned by tag (`"vue-journal-layer": "git+https://…/vue-journal-layer.git#v0.3.0"` [VERIFIED: sm-grzybyfunkcjonalne-app/vue-grzybyfunkcjonalne-app/package.json:20-22]), so each layer needs a new tag plus a site bump.
+
+### Pattern 9: API docs (D-16/D-17)
+PHP serves `GET api-docs` (inline HTML) and `GET api-docs.json` (YAML parsed once, process-cached, `JSON_UNESCAPED_SLASHES`, 500 "API specification is unavailable." without leaking a path) [VERIFIED: wavepath.org …/ApiDocsController.php; routes.php:1086-1087]. PHP loads `https://cdn.jsdelivr.net/npm/swagger-ui-dist@5` **without** `integrity`. Go: a surf-defined optional interface (`surf.APIDocsProvider { APIDocsSpec() ([]byte, error) }`, type-asserted like `BucketProvider` [router.go:121-126]); boot error when `http.api_docs.enabled` is true and zero or more than one provider exists. Convert with `yaml.YAMLToJSON` then `json.Compact`, once at boot. Mount with `GroupRaw` like `mountUploads` [VERIFIED: modules/surf/uploads.go:148-170]. Config keys: `http.api_docs.enabled`, `http.api_docs.path` (default `/api-docs`; JSON at `<path>.json`), optional `http.api_docs.title`.

+(5.33.2 bundle is `sha384-gNnUp++d7WqR9OKX4OMoUmV2w0JxEs1uu6NPXgcynGClIX5DOu6ol4Lp+lINyZcJ`; its css and preset hashes equal 5.33.1's.) Use `<link … integrity="…" crossorigin="anonymous">` and `<script … integrity="…" crossorigin="anonymous">`, and pass the spec URL into `SwaggerUIBundle({url: …})` from config with `html/template` escaping.
+
+### Anti-Patterns to Avoid
+- **`FLUSHDB` for `Cache.Flush`** (Laravel's Redis store does this): it wipes rate-limit counters and every other app on the same DB. Use `SCAN MATCH <prefix>cache:*` plus `UNLINK` in batches.
+- **Publishing the Redis store from `BuildRouter`**: `route:list` would dial Redis.
+- **Shared key space for cache and limiter**: use `<prefix>cache:` and `<prefix>rl:`.
+- **Route-level CORS without OPTIONS routes**: preflights get a 405.
+- **`mime.ExtensionsByType` for disk names**: host-dependent output.
+
+## Don't Hand-Roll
+
+| Problem | Don't Build | Use Instead | Why |
+|---------|-------------|-------------|-----|
+| Bounded TTL cache | map + LRU + sweeper | otter v2 | Eviction, per-entry expiry and lock-scoped compute are subtle |
+| Redis protocol, pooling, scripts | raw RESP client | go-redis v9 `NewScript`/`Run` | EVALSHA/NOSCRIPT fallback, pooling, TLS (`rediss://`) |
+| S3 signing and endpoints | AWS SigV4 client | gocloud `s3blob` (tagged) | Checksums and path style are already URL params |
+| Cookie serialization | string building | `http.SetCookie` + `(*http.Cookie).Valid()` | Domain validation and attribute escaping |
+| YAML→JSON | custom walker | `goccy/go-yaml` `YAMLToJSON` | Keeps key order (`UseOrderedMap`) |
+| Atomic check-and-increment | GET then INCR from Go | single Lua script | Two round trips race across instances |
+| Site-cache purge HTTP | a new client per plugin | the existing Journal purger moved to `cooler` | Already hardened (loopback-only http, token length, no token in logs) |
+
+**Key insight:** in this phase every library choice is small; the risk is in seams (boot order, ServeMux preflights, manifest round-trips, a second `go build`).
+
+## Common Pitfalls
+
+### Pitfall 1: Go strips the leading dot of a cookie Domain and silently drops an invalid one
+**What goes wrong:** `Domain: ".example.com"` is written as `Domain=example.com`; an invalid domain is logged and dropped, which makes a host-only cookie, so refresh breaks across subdomains without any error [VERIFIED: GOROOT net/http/cookie.go:277-292].
+**How to avoid:** validate `auth.cookie.domain` at boot with `(*http.Cookie).Valid()`. Expect byte differences from PHP's `domain=.x` in parity fixtures (browsers treat both the same).
+
+### Pitfall 2: Cookie Max-Age from `ttl` instead of `refresh_ttl`
+**What goes wrong:** the cookie dies with the access token and the SPA loops on re-login (PHP comment, AuthApiController.php:344-349). **How to avoid:** the builder takes `refreshTTL`, and a test asserts `MaxAge == refresh_ttl*60`.
+
+### Pitfall 3: CORS `*` + credentials (php-cors reflects any origin)
+**How to avoid:** boot error (D-04). **Warning sign:** a config that "works" with credentials and `*` in PHP.
+
+### Pitfall 4: Missing `Vary: Origin` on dynamic CORS answers
+**What goes wrong:** a shared cache stores a response without `Access-Control-Allow-Origin` (or with another origin) and serves it to a different origin. **How to avoid:** always `Vary: Origin` on CORS paths when the origin answer is dynamic, including preflight (D-04).
+
+### Pitfall 5: `cors:<profile>` never sees preflights
+**What goes wrong:** ServeMux returns 405 for `OPTIONS` on `GET /x` before middleware [ASSUMED: Go 1.22+ ServeMux method-mismatch behaviour; confirm with a router test]. **How to avoid:** register `OPTIONS` routes for profiled routes, plus a boot check against overlap with global `http.cors.paths`.
+
+### Pitfall 6: App build scripts drop the S3 tag
+**What goes wrong:** `scripts/build.sh` runs `summer build`, then `CGO_ENABLED=0 GOOS=linux GOARCH=amd64 go -C "$ROOT" build -trimpath -o bin/grzybyfunkcjonalne .` [VERIFIED: sm-grzybyfunkcjonalne-app/scripts/build.sh:52], with no tags. **How to avoid:** the D-13 boot error names the tag; the docs tell raw `go build` users to add `-tags summercms_s3` (or `GOFLAGS=-tags=summercms_s3`). Optionally `summer build` can print the tag line.
+
+### Pitfall 7: Redis URL credentials leak through errors
+**What goes wrong:** `url.Parse` errors echo the whole URL. Probe: `parse "redis://user:s3cretpw@host:6379/0\x7f": net/url: invalid control character in URL` [VERIFIED: go run, this session]. **How to avoid:** wrap as `cooler: redis.url is invalid` without `%w` of the raw error, or redact; never log the URL.
+
+### Pitfall 8: Extension "fix" that breaks downloads
+**What goes wrong:** blindly mapping the sniffed type renames `.docx`/`.xlsx` to `.zip` and `.ics` to `.txt`. **How to avoid:** apply rule 2 of Pattern 6 (keep a consistent or non-script client extension for generic sniffs).
+
+### Pitfall 9: cabana reorder runs no controller hook
+**What goes wrong:** `reorderPost` updates sort/parent columns with `UpdateColumns` inside a transaction and calls no `pact` hook [VERIFIED: modules/cabana/reorder.go:297-358], so menu-entry reorders cannot purge today. `deleteRecord` does run `pact.FormAfterDelete` (single and bulk) [VERIFIED: modules/cabana/crud.go:1025-1040, callers crud.go:274,328]. **How to avoid:** add an optional `pact` interface (for example `ReorderAfterSave(ctx context.Context) error`) called inside the reorder transaction (so `cabana.TxFromContext` works). That is a framework change in cabana/pact with README/docs updates; check for in-flight cabana edits first.
+
+### Pitfall 10: The Nitro route cache swallows the purge route
+**What goes wrong:** with a site rule `'/**': { swr }`, Nitro wraps every matching handler in its cached handler, so the purge answers from cache [VERIFIED: vue-journal-layer/nuxt.config.ts:45-50 comment and rule `'/api/__journal__/**': { cache: false }`]. **How to avoid:** every layer that ships the shared route also ships its `cache: false` rule.
+
+### Pitfall 11: `SaveManifest` drops new summer.yaml keys
+See Pattern 5. Add a round-trip test.
+
+### Pitfall 12: The Turnstile middleware consumes the body
+**How to avoid:** buffer (already capped), parse, restore `r.Body`. Also the PHP guest path validates `name` before Turnstile; a middleware runs before the handler, so the error order changes. Offer the verifier for in-handler use where parity on error order matters.
+
+### Pitfall 13: Redis outage behaviour of the rate limiter
+`Attempt` cannot return an error. **Recommend:** on a Redis error, fall back to a per-instance `MemoryStore` passed in by `surf`, and log once per interval. The alternatives are deny-all (an outage becomes a site-wide 429) or allow-all (the limit disappears).
+
+### Pitfall 14: go-redis default handshakes against miniredis and older servers
+go-redis v9.23.0 defaults `maintnotifications` to `ModeAuto` ("Client tries to send command, disables feature on error") and sends `CLIENT SETINFO` unless `DisableIdentity` is set [VERIFIED: go-redis@v9.23.0/maintnotifications/config.go:18-20,71,138; options.go:406-416,441-446]. **Recommend:** set `MaintNotificationsConfig: &maintnotifications.Config{Mode: maintnotifications.ModeDisabled}` and `DisableIdentity: true` in `cooler` for quiet logs.
+
+### Pitfall 15: `public_url` bypasses the `is_public` check
+**What goes wrong:** the proxy route serves only `is_public` rows (`StaticHandlerPublic`); a public-read bucket or CDN serves any key, private files included (keys are 22 random hex characters). **How to avoid:** document that `public_url` requires a bucket holding only public files, or accept unguessable keys knowingly. Optionally use `public_url` only when `IsPublic` is set.
+
+## Code Examples
+
+### Memory driver with per-entry TTL (otter v2)
+```go
+// Source: otter@v2.3.0 options.go / expiry_calculator.go / cache.go (verified API names)
+type entry struct{ val []byte; ttl time.Duration } // ttl<=0 means forever
+const forever = 50 * 365 * 24 * time.Hour
+c, err := otter.New(&otter.Options[string, entry]{
+	MaximumSize: cfgMaxEntries, // cache.memory.max_entries, e.g. 10000
+	ExpiryCalculator: otter.ExpiryWritingFunc(func(e otter.Entry[string, entry]) time.Duration {
+		if e.Value.ttl <= 0 { return forever }
+		return e.Value.ttl
+	}),
+})
+// Increment: atomic per key; it keeps the existing TTL via entry.ttl, as Redis INCRBY does.
+v, _ := c.Compute(key, func(old entry, found bool) (entry, otter.ComputeOp) {
+	n := int64(0)
+	if found { n, _ = strconv.ParseInt(string(old.val), 10, 64) }
+	return entry{val: []byte(strconv.FormatInt(n+by, 10)), ttl: old.ttl}, otter.WriteOp
+})
+```
+(Check `ExpiryWritingFunc` update semantics during implementation: it recomputes on update, so carry `ttl` in the value as shown. Note `ttl` here is the original duration, so an Increment restarts the window; if exact Redis semantics matter, store an absolute `expiresAt` and return `time.Until(expiresAt)`.)
+
+### Redis client from `redis.url`
+```go
+// Source: go-redis@v9.23.0 options.go:875-905 (ParseURL supports redis://, rediss://, unix://; unknown query params error)
+opt, err := redis.ParseURL(raw)
+if err != nil { return nil, errors.New("cooler: redis.url is not a valid redis:// rediss:// or unix:// URL") } // never echo raw
+opt.DisableIdentity = true
+opt.MaintNotificationsConfig = &maintnotifications.Config{Mode: maintnotifications.ModeDisabled}
+client := redis.NewClient(opt)
+pctx, cancel := context.WithTimeout(ctx, 3*time.Second); defer cancel()
+if err := client.Ping(pctx).Err(); err != nil { return nil, fmt.Errorf("cooler: redis ping failed: %v", redactErr(err)) }
+```
+
+### Docker-gated real-Redis test (mirror the postcard pattern)
+```go
+func TestMain(m *testing.M) {
+	flag.Parse()
+	if testing.Short() { os.Exit(m.Run()) }
+	ctx := context.Background()
+	ctr, err := testcontainers.Run(ctx, "redis:7-alpine",
+		testcontainers.WithExposedPorts("6379/tcp"),
+		testcontainers.WithWaitStrategy(wait.ForListeningPort("6379/tcp")))
+	// … set redisURL, run, testcontainers.TerminateContainer(ctr)
+}
+```
+
+## State of the Art
+
+| Old Approach | Current Approach | When Changed | Impact |
+|--------------|------------------|--------------|--------|
+| Floating `swagger-ui-dist@5` CDN without integrity (PHP) | exact version + SRI | — | A floating version cannot carry SRI |
+| AWS SDK default request checksums everywhere | `request_checksum_calculation=when_required` for S3-compatible stores | SDK v2 2025 defaults [ASSUMED date] | Some MinIO/R2/Hetzner setups reject the default CRC checksums [ASSUMED]; the URL params exist [VERIFIED] |
+| Per-instance rate limits (`surf.MemoryStore`) | Redis fixed window shared by instances | this phase | `docs/services/rate-limiting.md` currently says "each application instance counts on its own" and must be updated |
+
+**Deprecated/outdated:** `gopkg.in/yaml.v3` (archived, project rule); the go-redis `DisableIndentity` misspelling (deprecated, use `DisableIdentity`) [VERIFIED: options.go:406-416].
+
+## Docs checker constraints
+
+- `summer docs:build --check` / `go test ./cmd/summer -run TestDocsTree` checks identifiers, links, anchors, `src=` snippets and command names. Identifiers are indexed from the non-test Go files of every directory under `modules/`, keyed by the **last path element**. Two packages with the same last element are a problem [VERIFIED: internal/docsite/check_identifiers.go:20-60], so do not name a sub-package after an existing package (no `modules/cooler/redis` if anything else is `redis`; prefer files in `cooler`).
+- Every module directory with Go files needs a `README.md`; READMEs are published in the `api` section automatically [VERIFIED: internal/docsite/load.go:318-344].
+- The forbidden-name check is `regexp.MustCompile(`(?i)fonoteka|p[lł][yý]tarium`)` [VERIFIED: internal/docsite/check_forbidden.go:14]. WavePath is not covered, so review by hand (or extend the pattern in this phase).
+- `go/parser` indexes build-tagged files regardless of tags, so identifiers in `s3_on.go` count.
+- Pages to touch: `docs/services/rate-limiting.md` (Redis store), `docs/services/storage.md` (S3, `public_url`, extension, nosniff/allow-list deploy note), `docs/services/authentication.md` (cookie transport, Turnstile), `docs/services/routing.md` (CORS hardening, profiles, OPTIONS, api-docs), `docs/database/attachments.md` (disk name), a new `docs/services/caching.md`, and the `summer build` pages (`docs/console/*`) for `build.tags`.
+
+## Assumptions Log
+
+| # | Claim | Section | Risk if Wrong |
+|---|-------|---------|---------------|
+| A1 | ServeMux answers OPTIONS on a GET-only pattern with 405 before middleware | Pitfall 5 | Profile preflight design is wrong; a router test settles it in minutes |
+| A2 | S3-compatible stores (R2/MinIO/Hetzner) may reject the SDK's default checksums; `when_required` fixes it | Pattern 5, State of the Art | Uploads to a provider fail; documented URL params mitigate |
+| A3 | miniredis is a suitable test double (name from training; existence and features verified) | Standard Stack | Needs the decision note and user confirmation as a new test dependency |
+| A4 | Nitro's first-wins dedupe follows layer priority (project first) | Pattern 8 | Harmless if the route files are identical; diverging copies would make the winner layer-order dependent |
+| A5 | Laravel's cache prefix default is `slug(APP_NAME,'_').'_cache_'`; recommend `cache.prefix` defaulting from `app.name` | cooler config | Cosmetic; only matters for key layout docs |
+| A6 | Symfony serializes PHP cookies as lower-case attributes (`path=/; domain=…; secure; httponly; samesite=lax`) | Pitfall 1 | Parity fixtures that compare Set-Cookie bytes need normalization |
+| A7 | Fallback-to-memory is the preferred Redis-outage behaviour for rate limits | Pitfall 13 | Product choice; confirmed by the user (Open Questions Q3) |
+
+## Open Questions (RESOLVED)
+
+All five questions were answered by the user during planning (2026-10-15). The answers below are authoritative and the plans follow them.
+
+1. **Shared Nuxt purge route: same file in three layers, or a new tiny layer repo?** (RESOLVED)
+   - What we know: Nitro dedupes duplicate routes (first wins), so three identical copies work without a new repo.
+   - What's unclear: whether the user prefers a new `vue-*-layer` repo (needs creating, and every site adds it to `extends`).
+   - Recommendation: three identical copies plus a test in each layer that compares the shared util file's hash.
+   - **RESOLVED:** the same route file is copied into `vue-journal-layer`, `vue-menu-layer` and `vue-faq-layer`, each with its own `'/api/__site__/**': { cache: false }` route rule. No new layer repo. (Plan 04.)
+2. **Turnstile env name.** PHP reads `TURNSTILE_SECRET`; compass maps only `SUMMER_*`. Recommendation: config key `turnstile.secret` (env `SUMMER_TURNSTILE__SECRET`), with the deploy docs mapping the old name. (RESOLVED)
+   - **RESOLVED:** config key `turnstile.secret`, set through `SUMMER_TURNSTILE__SECRET`; the docs record the mapping from the PHP `TURNSTILE_SECRET` variable. (Plan 02.)
+3. **Redis outage policy for rate limits** (A7). Recommendation: memory fallback plus a warning. (RESOLVED)
+   - **RESOLVED:** when Redis is down, the rate limiter falls back to a per-instance `surf.MemoryStore` and logs a warning. (Plan 01.)
+4. **Purge coalescing.** Debounce window (for example 250 ms trailing) vs one purge per commit. Recommendation: trailing debounce in `cooler`. (RESOLVED)
+   - **RESOLVED:** no debounce. One purge POST per committed save; the recommendation above is superseded. (Plan 04.)
+5. **Plan count.** Suggested lean split for the user to confirm: (1) decision notes + `cooler` cache/Redis store + serve wiring + caching/rate-limit docs; (2) bouncer cookies + Turnstile + surf CORS hardening/profiles + api-docs; (3) attach S3 tag + `summer.yaml` `build.tags` + `public_url` + extension helper; (4) site-cache purge in `cooler` + cabana reorder hook + Journal/menu/FAQ plugins + three vue layers + app pointer bumps; (5) unit tests. Plan 4 depends on plan 1; plans 2 and 3 are independent. (RESOLVED)
+   - **RESOLVED:** the 5-plan layout above is confirmed.

+- **Per wave merge:** the full suite command (Docker available) plus the tagged run.
+- **Phase gate:** full suite + tagged run + docs checker green before `/msd-verify-work`; plugin repos' `go test ./...` from an app checkout; layer `pnpm test`.

+| ASVS Category | Applies | Standard Control |
+|---------------|---------|-----------------|
+| V2 Authentication | yes (Turnstile anti-automation) | `bouncer` verifier against Cloudflare siteverify; secret server-side only |
+| V3 Session Management | yes (token cookie) | httpOnly, Secure, SameSite=Lax, Max-Age=refresh window, rotation + JTI blacklist (`bouncer.Refresh*`, Postgres blacklist) |

+| V5 Input Validation | yes | Upload sniffing + extension helper; config validation at boot (cookie domain, CORS patterns, tags regex, purge URL) |
+| V6 Cryptography | no new crypto | Constant-time token compare stays in the Nuxt util (sha256 + timingSafeEqual) |
+| V12 Files and Resources | yes | Disk extension from content, nosniff + CSP sandbox on `/storage/uploads`, `public_url` exposure documented |
+| V14 Configuration | yes | Secrets via `SUMMER_*` env; Redis URL never logged; SRI on CDN assets |
+
+### Known Threat Patterns for this stack
+
+| Pattern | STRIDE | Standard Mitigation |
+|---------|--------|---------------------|
+| Credentialed CORS reflecting any origin | Information disclosure | Boot error for `*` + credentials; exact-origin echo; `Vary: Origin` |
+| Cache poisoning across origins | Tampering | `Vary: Origin` on every dynamic CORS response |
+| CSRF on cookie-authenticated endpoints from sibling subdomains (SameSite=Lax treats same-site as safe) | Spoofing/Tampering | CORS is not CSRF protection: require JSON or a custom header on state-changing cookie routes; optionally check `Origin` in the cookie handler against the allowed list |
+| Cookie scoped too widely (`Domain=.example.com` reaches every subdomain) | Information disclosure | Domain explicit and opt-in (default host-only); document the subdomain trust boundary |
+| Stored XSS via a disk-name extension | Tampering/Elevation | `DiskExtension` from the sniffed type; never keep script-capable extensions; nginx nosniff + allow-list |
+| Private files via `public_url` | Information disclosure | Bucket only for public files, or proxy route; document |
+| Turnstile bypass by an empty secret in production | Spoofing | Closed mode: 503 in production when unconfigured; open mode only on registration paths |
+| Turnstile token replay | Spoofing | Single-use enforced by Cloudflare (`timeout-or-duplicate`); never cache verdicts per token |
+| Siteverify hang causing request pile-up | DoS | 5 s client timeout; context-aware request |
+| Redis credential leak in logs | Information disclosure | Never format `redis.url` or raw `url.Parse` errors (Pitfall 7) |
+| Rate limit bypass during a Redis outage | DoS/Abuse | Memory fallback per instance plus a warning |
+| Redis key injection or collision | Tampering | Key prefixing `<prefix>rl:` / `<prefix>cache:`; keys are opaque strings to Redis (no command injection through go-redis args) |
+| CDN asset tampering on `/api-docs` | Tampering | Exact version + SRI sha384 + `crossorigin="anonymous"` |
+| Purge route abuse | DoS | Bearer ≥32 chars, constant-time compare, refuses proxied requests, nginx `limit_except GET HEAD` |

+Re-running the gate keeps every row it can. A row the current review no longer reports is kept and its Source cell flagged, so a finding does not leave this record silently. ONE exception: when a finding id is REUSED by a different finding, the earlier decision cannot keep a row — the id is taken — and it is dropped. A RECORDED decision (anything but `open`) is named on the console when that happens; a row still at `open` is replaced silently, because `open` records no decision to lose.

+# Phase 19.3: Code Review Report
+
+**Reviewed:** 2026-10-15T18:16:47Z
+**Depth:** standard
+**Files Reviewed:** 35 (framework sources, the plugins' purge wiring, the shared Nuxt purge route; tests got a lighter pass)
+**Status:** issues_found
+
+## Narrative Findings (AI reviewer)
+
+## Summary
+
+The phase is careful in most of the places the brief asked about. The Redis Lua script is atomic and matches `surf.MemoryStore`: a missing key or one without a TTL opens the window, a denied attempt does not increment, and INCR keeps the TTL. Keys are namespaced `<prefix>rl:` / `<prefix>cache:`, and Flush escapes SCAN glob characters. The S3 driver is linked only under `summercms_s3`, and an untagged binary refuses `s3://` at boot. Build tags are validated by regex and passed as a single exec argument. The api-docs template escapes the title and spec URL, and the assets carry SRI. The purge token is compared in constant time over sha256 digests. Every cabana write path that reaches the plugins' hooks (`crud.go:134`, `reorder.go:319`) now runs in `lagoon.Transaction`, so after-commit semantics hold.
+
+The defects are at the edges between modules:
+
+- The `cors:<profile>` middleware runs in declaration order. Responses from the guard, throttle, Turnstile, body limit or panic recovery therefore carry no CORS headers, and the browser cannot read them (CR-01).
+- The site-cache purge runs synchronously inside the admin request after commit, and bulk deletes repeat it per row.
+- The purge client follows redirects with the bearer token attached.
+- The shipped Nuxt route returns 404 to every proxied request, so the https mode that the Go side advertises cannot be used.
+- Several hardening gaps remain in credentialed CORS validation, cookie Secure inference, the api-docs CSP and Turnstile misconfiguration visibility.
+
+Already logged in `deferred-items.md` and not counted again: S3 object metadata keeps the sniffed `text/html` / `text/javascript` content type; Redis outage latency in `Cache.Remember` plus go-redis stderr logging; the unreachable "in transaction but no purger" plugin branch; the gofmt and consumer-name items.
+
+## Critical Issues
+
+### CR-01: `cors:<profile>` headers are missing from every response produced outside the profile middleware (401, 403, 413, 422, 429, 500)
+
+**File:** `modules/surf/router.go:416-466`, `modules/surf/cors.go:255-262`
+**Issue:** `wrap` composes route middleware so that `rt.middleware[0]` is outermost (`for i := len-1; i >= 0; i-- { h = mw(h) }`). It then puts `bodyLimit`, `r.locale` and `recoverJSON`/`recoverBare` outside all of them. `profileMiddleware` only sets `Access-Control-Allow-Origin` when the request reaches it. With the ordering the docs suggest (`docs/services/routing.md:265`: "lists `cors:spa` among its middleware names, next to its guard"), a route such as `[]string{"auth", "throttle:60,1", "turnstile:open", "cors:spa"}` answers:
+- a guard refusal (401, expired token),
+- a throttle denial (429),
+- a Turnstile refusal (422/503),
+- a body-limit trip (413, always outside), and
+- a recovered panic (500, always outside)
+
+all without ACAO, ACAC or `Vary: Origin`. The browser turns each of these into an opaque network error. A credentialed SPA, which is the use case profiles exist for, can no longer see the 401 that should trigger its cookie refresh, or the 422 that should re-show the Turnstile widget. The global `pathScopedCORS` wrapper does not have this problem because it runs before the mux.
+**Fix:** Apply the profile outside every other route layer, whatever position it has in the list. In `wrap`, take the `cors:` entry out of the loop and wrap it last, after `recoverJSON` and before `recordPattern`:
+```go
+profile, _ := routeCORSProfile(rt) // already validated in addCORSPreflights
+// ... loop skips names with base "cors" ...
+if rt.raw { h = recoverBare(h) } else { h = recoverJSON(h) }
+if profile != "" {
+    h = r.corsProfiles[profile].profileMiddleware(h)
+}
+return recordPattern(rt.method+" "+rt.path, h), nil
+```
+Add a test that sends a cross-origin request to a `cors:spa` route behind a refusing guard and asserts that the 401 carries `Access-Control-Allow-Origin`.
+
+## Warnings
+
+### WR-01: The site-cache purge runs synchronously in the admin request, and bulk delete multiplies it
+
+**File:** `modules/cooler/sitecache.go:123-195`, `modules/lagoon/transaction.go:86,194-205`, `modules/cabana/crud.go:1025-1040`
+**Issue:** `lagoon.Transaction` runs after-commit callbacks inline (`runAfterCommit` after `gdb.Transaction` returns). `PurgeSiteCacheAfterCommit` registers `p.Purge`, which is a blocking HTTP POST with a 2 s bound. Every admin save therefore waits for the Nuxt site. When the site is down or slow, each save takes up to 2 s longer. `BulkDelete` calls `deleteRecord` per row, and the FAQ, menu and menu-entry hooks each register a purge, so deleting N rows sends N sequential full-cache purges after commit. With N=50 and a hung site that is about 100 s, which is past typical server write timeouts. The client then sees a failed request for a delete that has committed. Each purge also wipes the whole `nitro:routes` cache (`siteCachePurge.ts:62-71`), so after the first purge the remaining N-1 do nothing.
+**Fix:** Coalesce per transaction and send asynchronously. One option is a purger method that marks "purge pending" in the after-commit buffer once per transaction (dedupe on the `*SiteCachePurger`). Another is to make `Purge` enqueue onto a single background worker with a small debounce, for example:
+```go
+func (p *SiteCachePurger) Purge(ctx context.Context, kind, slug string) {
+    if p == nil { return }
+    select { case p.queue <- siteCachePurgeBody{kind, slug}: default: /* one already pending */ }
+}
+```
+Document that the purge is fire-and-forget.
+
+### WR-02: The purge client follows redirects and forwards the bearer token, including https-to-http on the same host
+
+**File:** `modules/cooler/sitecache.go:93,148`
+**Issue:** `&http.Client{}` uses the default redirect policy. Go forwards `Authorization` on a redirect when the destination hostname equals the original or is a subdomain of it, and it ignores the scheme and port. A purge URL `https://site.example.com/api/__site__/cache/purge` that answers 301/302/307/308 to `http://site.example.com/...` (a common proxy misconfiguration, or a trailing-slash redirect behind a TLS terminator) therefore sends the token in clear. `NewSiteCachePurgerFor` (lines 87-89) exists to prevent exactly that. A 301/302 also turns the POST into a GET, so the purge silently does nothing.
+**Fix:**
+```go
+client: &http.Client{CheckRedirect: func(*http.Request, []*http.Request) error { return http.ErrUseLastResponse }},
+```
+A 3xx then logs as `site cache purge failed status=30x`.
+
+### WR-03: The shipped purge route refuses every proxied request, so the https/remote mode the Go side advertises cannot work
+
+**File:** `/media/nvme/dev/golem15/summercms.io/summercms/vue-faq-layer/server/api/__site__/cache/purge.post.ts:109-121`, `modules/cooler/sitecache.go:60-63,87-89`
+**Issue:** On the Go side, `site_cache.purge_url` accepts any https host ("use https for any other host"). The route that all three layers ship returns 404 whenever `X-Forwarded-For`, `X-Real-IP` or `Forwarded` is present. A remote https endpoint is reached through a TLS-terminating proxy almost by definition, and nginx, Caddy and Traefik add those headers by default. The configuration therefore passes boot validation and fails every save with `status=404`. Operators get a warning per save and no explanation. The two halves of one feature disagree about the threat model.
+**Fix:** Pick one model. Either restrict `purge_url` to loopback hosts in `NewSiteCachePurgerFor` (drop the https/remote allowance and its docs), or let the route accept proxied requests when an explicit runtime flag is set (for example `siteCache.allowProxied`), relying on the bearer token alone, and document the pairing in `docs/services/caching.md`.
+
+### WR-04: Credentialed CORS validation only refuses a bare `*`; a wildcard entry or an unanchored pattern still trusts arbitrary origins with credentials
+
+**File:** `modules/surf/cors.go:45-58,79-88,120-137`
+**Issue:** `validateCORSConfig` rejects `supports_credentials: true` only when `allowed_origins` contains exactly `"*"`. These still pass:
+- `allowed_origins: ["https://*"]` or `["*://*"]`, which `wildcardOriginPattern` turns into `^https://.*$` and which trusts every https origin with credentials;
+- `allowed_origins_patterns: ["https://.*\\.example\\.com"]` (delimiters stripped, as the error message tells PHP users to do, but without `^`/`$`), which `MatchString` treats as a substring match, so `https://x.example.com.attacker.net` is reflected with `Access-Control-Allow-Credentials: true`.
+
+The phase made "credentials with `*` is a boot error" a deliberate hardening step (02-SUMMARY), and these are the same exposure under a different spelling.
+**Fix:** When `SupportsCredentials` is true:
+- require every `allowed_origins_patterns` entry to start with `^` and end with `$` (or anchor them yourself with `^(?:` + p + `)$` in `newCORSPolicy`);
+- refuse wildcard origins whose host part is only `*` (for example, require at least one literal label after the `*`, as in `https://*.example.com`).
+
+Add these cases to `TestCORSCredentialsWildcardRefused`.
+
+### WR-05: In production, the cookie's Secure flag is inferred false without an error when `app.url` is http or unset
+
+**File:** `modules/bouncer/cookie.go:100-107,116-121`
+**Issue:** The production guard only refuses an *explicit* `auth.cookie.secure: false`. When the key is unset, `cookieSecure` derives Secure from `app.url`. If `app.url` is missing, mistyped or `http://` (common when TLS terminates at a proxy and `APP_URL` was copied from a dev `.env`), production writes the httpOnly auth token cookie without `Secure`, and nothing errors or warns. `SameSite=None` is caught; Lax/Strict are not.
+**Fix:** In the production environment, treat an inferred `secure=false` like an explicit one:
+```go
+if !secure && strings.EqualFold(strings.TrimSpace(src.Environment()), "production") {
+    return cfg, errors.New("bouncer: auth.cookie.secure resolves to false in production (app.url is not https); set app.url to https or auth.cookie.secure: true")
+}
+```
+At the least, log a warning naming `app.url`.
+
+### WR-06: The api-docs CSP allowlists all of jsDelivr for scripts, which cancels the nonce
+
+**File:** `modules/surf/apidocs.go:207`
+**Issue:** `script-src 'nonce-…' https://cdn.jsdelivr.net` lets any script from jsDelivr execute, and that includes every npm package and every GitHub repo (`/gh/<user>/<repo>`). Any HTML injection on the page (Swagger UI renders `description` markdown from the spec, and Swagger UI has a history of DOM XSS) can load attacker code from jsDelivr without a nonce. The SRI attributes protect only the three tags that carry them. The policy also has no `default-src`, `style-src` or `connect-src`.
+**Fix:** Add the nonce to the three external `<script>` tags as well (`<script nonce="{{.Nonce}}" src=… integrity=…>`) and drop the host source: `script-src 'nonce-X'; style-src https://cdn.jsdelivr.net/npm/swagger-ui-dist@5.33.1/ 'unsafe-inline'; default-src 'self'; img-src 'self' data:; object-src 'none'; base-uri 'none'; frame-ancestors 'none'`. Alternatively, pin the host source to the exact path `https://cdn.jsdelivr.net/npm/swagger-ui-dist@5.33.1/`.
+
+### WR-07: `storage.uploads.public_url` puts protected (`is_public=false`) files in a publicly served bucket
+
+**File:** `modules/lagoon/attach/bucket.go:131-155`, `modules/lagoon/attach/store.go:155-172`
+**Issue:** With `public_url` set, the bucket is served directly by the CDN/S3 host, and that host "serves any key without the is_public check" (the info log at line 151). `Store` still writes every upload to that one bucket, including those from protected relations (`Relation.Public == false`, which cabana serves through `serveProtectedFile`). The protection then rests only on the 88-bit random key staying secret. Common public-bucket setups that allow `s3:ListBucket`, CDN access logs, and any leak of the disk name expose protected files. The only safeguard is an Info-level log line.
+**Fix:** When `public_url` is set, either refuse to store `Public: false` uploads (`ErrProtectedNeedsPrivateBucket`), or write protected files under a key prefix that the operator is told to deny publicly (for example `protected/…`) and check it at boot. At minimum, raise the log line to Warn and state in `docs/services/storage.md` that protected relations must not be used with `public_url`.
+
+### WR-08: `turnstile:open` without a secret switches off bot protection in production, with nothing logged
+
+**File:** `modules/surf/router.go:648-661`, `modules/bouncer/turnstile.go:105-111`
+**Issue:** Open mode passes every request when `turnstile.secret` is empty, in every environment. Closed mode passes outside an environment named exactly `production` (so also `staging` and `prod`). This matches PHP, but surf builds the verifier once at boot and never reports that routes declaring `turnstile:*` are unprotected. A missing `SUMMER_TURNSTILE__SECRET` on deploy silently opens registration to bots.
+**Fix:** After `wrap` has validated the routes, if any route names `turnstile:open|closed` and `buildTurnstile` returned an empty secret, log one Warn at boot ("turnstile.secret is empty: N routes accept requests without a Turnstile check"). Consider making it a boot error in production for `turnstile:closed`.
+
+### WR-09: The zero `CookieConfig` does not give the documented default attributes (no SameSite, no Secure)
+
+**File:** `modules/bouncer/cookie.go:24-37,262-272`
+**Issue:** The field docs say SameSite "is http.SameSiteLaxMode unless auth.cookie.same_site says otherwise", and `withDefaults` says "a zero CookieConfig writes the default token cookie on '/'". `withDefaults` fills only Name and Path. A handler built with `CookieRefreshOptions{Cookie: bouncer.CookieConfig{}}` (an easy mistake in an app that skips `LoadCookieConfig`) writes the auth token cookie with no `SameSite` attribute, which Safari treats as None, and without `Secure`.
+**Fix:** In `withDefaults`, set `if c.SameSite == 0 { c.SameSite = http.SameSiteLaxMode }`, and either make `CookieRefreshHandler`/`CookieLogoutHandler` reject a config not produced by `LoadCookieConfig` or document that a zero config is insecure.
+
+## Info
+
+### IN-01: The cache prefix has no enforced separator, so one application's Flush can reach another's keys
+
+**File:** `modules/cooler/cooler.go:335-347`, `modules/cooler/rediscache.go:199-220`
+**Issue:** `cache.prefix` is used verbatim. Prefix `acme` gives `acmecache:*`, and that SCAN MATCH also matches an application whose prefix is `acmecache:` (`acmecache:cache:x`). Similarly, `acme:` flushes keys of an application prefixed `acme:cache:`. The default prefix is the slug of `app.name`, so staging and production of one app that share a Redis database also share cache and rate-limit counters, and one Flush clears both.
+**Fix:** Append `:` when the configured prefix does not end in one, and mention `cache.prefix` per environment in the caching guide.
+
+### IN-02: The purge token is not trimmed although the URL is
+
+**File:** `modules/cooler/sitecache.go:67-93`
+**Issue:** A token read from an env file with a trailing newline or space passes the length check. Go then refuses to send the header (`invalid header field value`), or the Nuxt comparison fails. The result is a warning on every save with no hint at the cause.
+**Fix:** `token = strings.TrimSpace(token)` (and the same in the Journal's alias check at `plugin.go:79`).
+
+### IN-03: The purge and the Journal alias wiring log through `slog.Default()` instead of the app logger
+
+**File:** `modules/cooler/sitecache.go:132`, `/media/nvme/dev/golem15/summercms.io/summercms/sm-journal-plugin/plugin.go:75`
+**Issue:** Install and the cache drivers use `loggerFromApp`. `Purge` and `wireSiteCache` do not, so their lines bypass any app-published logger (format, level, destination).
+**Fix:** Keep the logger on `SiteCachePurger` (set it in `installSiteCache`/`SiteCacheFromApp`) and use it in `Purge`.
+
+### IN-04: `SiteCacheFromApp` logs an Error on every call when the configuration is invalid
+
+**File:** `modules/cooler/sitecache.go:211-214`
+**Issue:** Outside serve (job workers, console commands), each admin-hook call rebuilds, fails and logs again.
+**Fix:** Cache the failure, for example by publishing a sentinel, or log through a `warner`.
+
+### IN-05: The Turnstile middleware buffers the whole body even for content types it never parses
+
+**File:** `modules/bouncer/turnstile.go:252-286`
+**Issue:** The body is read into memory before the media type is checked. On a route with an upload-sized `body.limit`, a multipart request with no token is buffered in full before it is refused, which is pre-auth memory pressure. Multipart forms are also never searched for the token, so an HTML form with a file input always fails.
+**Fix:** Parse `Content-Type` first, read the body only for JSON or urlencoded types, and either support `multipart/form-data` through `r.ParseMultipartForm` or document that it is unsupported.
+
+### IN-06: Each preflight route copies the constraints of the first route on its path only
+
+**File:** `modules/surf/cors.go:320-345`
+**Issue:** When several routes share a path pattern but declare different constraints, the OPTIONS route uses the constraints of the first one in `r.routes`, so a valid preflight for another route can get 404. The overlap check against `http.cors.paths` matches the route *pattern* text (`/api/{slug}`) against globs, so a global glob such as `api/posts` that matches real requests to a profiled `/api/{slug}` route is not detected.
+**Fix:** Merge constraints (accept when any route's constraints match), and test the global globs against a sample path built from each pattern.
+
+### IN-07: The `DiskExtension` script-capable denylist is incomplete
+
+**File:** `modules/lagoon/attach/diskext.go:39-42`
+**Issue:** The list omits extensions that common server setups execute or render: `php3`-`php8`, `phps`, `asp`, `aspx`, `jsp`, `cgi`, `pl`, `py`, `mht`, `mhtml`. The extension allowlist runs first (`store.go:128`), so this matters only when an application widens `Limits.Extensions`, but the denylist is meant to be the backstop for that case.
+**Fix:** Add those extensions, or match `^php\d*$|^pht` style families.
+
+### IN-08: The cookie refresh and logout handlers do not check `Origin`
+
+**File:** `modules/bouncer/cookie.go:213-260`
+**Issue:** With `same_site: none` (allowed when Secure), a cross-site form POST can rotate or revoke the user's token (logout CSRF). This is low impact but has an easy fix.
+**Fix:** Optionally verify `Origin`/`Sec-Fetch-Site` against the CORS profile's allowed origins when `SameSite` is None.
+
+### IN-09: Timing-sensitive cooler unit tests may flake on loaded CI
+
+**File:** `modules/cooler/memory_test.go:142-170`, `modules/cooler/install_test.go:224`
+**Issue:** The tests assert that a 40 ms entry is present right after Set, a 60 ms TTL around `Increment`, and that `FromApp` finishes in under 100 ms. These can fail under CPU contention, and the phase gate fails on any test failure.
+**Fix:** Use TTLs of at least 1 s with an injected clock, or widen the margins (for example, assert presence with a 1 s TTL and absence after the TTL plus a poll loop).
+
+### IN-10: The `purgeSiteCache` helper is copied across the FAQ and menu plugins, with a third variant in the Journal
+
+**File:** `/media/nvme/dev/golem15/summercms.io/summercms/sm-faq-plugin/controllers/site_cache.go:15-32`, `/media/nvme/dev/golem15/summercms.io/summercms/sm-menu-plugin/controllers/site_cache.go:15-32`, `/media/nvme/dev/golem15/summercms.io/summercms/sm-journal-plugin/controllers/site_cache.go:19-36`
+**Issue:** These are the same logic (app nil check, `cabana.TxFromContext`, `SiteCacheFromApp`, `PurgeSiteCacheAfterCommit`) in three places. A fix for WR-01 would need three plugin releases.
+**Fix:** Add a framework helper such as `cabana.PurgeSiteCacheOnSave(ctx, app, kind, slug)` (cabana already imports lagoon, and cooler does not import cabana), and have the plugins call it.
+
+### IN-11: A published `*bouncer.Turnstile` silently overrides `turnstile.secret`
+
+**File:** `modules/surf/router.go:655-657`
+**Issue:** This seam was added for tests (02-SUMMARY deviation 1). Any plugin can publish a verifier with an empty secret and `Production: false` and switch off Turnstile application-wide, and nothing logs it.
+**Fix:** Log at boot when a published verifier replaces a configured secret.

+## Tests

+### 1. Cookie refresh across real api/www subdomains in a browser. Deploy to staging with auth.cookie.domain set to the parent domain and cors:<profile> (or http.cors) credentialed for the www origin. Log in on www, wait past the access TTL.
+expected: The SPA reads the 401, the refresh call sends the cookie, the rotated cookie replaces the old one, the replayed old token answers 401.
+result: [pending]
+
+### 2. S3-compatible upload. Build with build.tags [summercms_s3], set storage bucket_url s3://...?endpoint=..., upload a public file, fetch it via storage.uploads.public_url and via /storage/uploads; try a protected (is_public false) upload with public_url set.
+expected: Both URLs serve the public file; the protected upload is refused with attach.ErrProtectedNeedsPrivateBucket (admin answers the opaque 500 and logs the reason).
+result: [pending]
+
+### 3. Live Nuxt purge. Save a menu entry and a FAQ entry in admin against a running Nuxt site using the 0.3.0/0.5.0 layers; for a proxied deployment set NUXT_SITE_CACHE_ALLOW_PROXIED=true.
+expected: The page updates without waiting for the 300 s SWR TTL; the app log shows 'cooler: site cache purged' after the save returned.
+result: [pending]
+
+### 4. Swagger UI under its new nonce-only CSP. Enable http.api_docs, open /api-docs in a browser.
+expected: The UI renders the spec with no CSP violations in the console (script-src is now only 'nonce-...').
+result: [pending]

+# Phase 19.3: Framework transport and infrastructure for WavePath Verification Report
+
+**Phase Goal:** The framework has the transport and infrastructure pieces a multi-client, multi-instance application needs: JWT cookie refresh across subdomains, credentialed CORS, a cache module with a Redis-backed rate-limit store, an S3 blob option, an OpenAPI page and Turnstile verification.
+**Mode:** mvp (ROADMAP marks the phase `mode: mvp`, but the goal is not written as a user story; as in the initial report, this report uses standard goal-backward verification with a derived User Flow Coverage table. Run `/msd mvp-phase 19.3` to restate the goal, or drop `mode: mvp`, to make the mode consistent.)
+**Verified:** 2026-10-15T21:08:52Z (HEAD `c5d9a7b`, local master, not yet tagged or pushed: expected, the release follows verification)
+**Status:** human_needed
+**Re-verification:** Yes, after gap-closure plan 19.3-06

+## Re-verification Summary
+
+| Item | Previous (2026-10-15T20:45Z) | Now | Evidence |
+|------|------------------------------|-----|----------|
+| SC-1 / D-05, CR-01: `cors:<profile>` headers on refusals, 413, 500 | ✗ FAILED (partial) | ✓ VERIFIED | Verifier probe (below) on HEAD: 11/11 PASS. Same probe on the pre-fix tree `0723536^`: 7/11 FAIL. `TestCORSProfileHeadersOnRefusals` and `TestCORSProfileVaryKeptWithHandlerVary` are required by name in `SURF_TESTS` and passed in the gate |
+| WR-01..WR-09 (warnings) | open | fixed, verified in code and by named tests | see Plan 06 must-haves |
+| Previously verified must-haves (35) | ✓ | ✓ no regressions | full gate with Docker green; cross-instance smokes and `go test -short ./...` green |
+
+### Resolved gap (history)
+
+The initial verification recorded one gap. `Router.wrap` composed `cors:<profile>` at its list position, inside the body limit and panic recovery. A guard listed before the profile, a guard on an enclosing group and a recovered 500 therefore answered without `Access-Control-Allow-Origin`, and the browser hid the 401 that starts the SPA's cookie refresh. Plan 06 (commit `0723536`) resolves the profile through `routeCORSProfile`, skips the `cors:` entry in the middleware loop after the unknown-profile check, and wraps the recovered handler in `r.corsProfiles[profile].profileMiddleware` just inside `recordPattern` (`modules/surf/router.go:417-485`). `bufferedResponse.commit` now merges `Vary` through `addVary` instead of replacing it (`router.go:837-852`), so a handler's own `Vary` does not drop `Vary: Origin`. The docs say the profile applies whatever its position: `docs/services/routing.md:101,271`, `modules/surf/README.md:31` and `docs/architecture/request-lifecycle.md:40`.
+
+## User Flow Coverage (derived; the goal is not a user story)
+
+Flow: a SPA on `www.example.com` talks to an API on `api.example.com` run as several instances.
+
+| Step | Expected | Evidence | Status |
+|------|----------|----------|--------|
+| Log in, get a cookie | httpOnly `token` cookie, Domain/SameSite/Secure from `auth.cookie.*`, Max-Age = refresh window; production refuses an insecure cookie | `bouncer.LoadCookieConfig`, `CookieConfig.TokenCookie`; `TestTokenCookieMaxAgeIsRefreshWindow`, `TestLoadCookieConfigProductionInferredSecure`, `TestZeroCookieConfigDefaults` passed | VERIFIED |
+| Access token expires, API answers 401 | The SPA can read the 401 cross-origin | Global `http.cors`: verified in the initial run. `cors:<profile>`: 401 carries ACAO+ACAC+Vary whatever the order or group nesting (probe, this run) | VERIFIED (real browser: human item 1) |
+| Refresh through the cookie | New cookie, old jti blacklisted, replay refused | `TestCookieRefreshHandlerRotatesAndBlacklists` (real `bouncer.Refresh`), `TestCookieRefreshAcrossSubdomainsSmoke` passed in this run | VERIFIED |
+| Requests land on different instances | Throttle counts one window across instances | `TestRateLimitAcrossInstancesSmoke` (two apps, one real Redis container) passed in this run; the 429 also carries the profile's CORS headers (probe) | VERIFIED |
+| Upload a file to S3 | `bucket_url: s3://` in a tagged binary, no app import | `s3_on.go`/`s3_off.go`; `TestOpenBucketS3` in both tag modes; protected uploads refused when `public_url` is set (`TestStoreProtectedNeedsPrivateBucket`) | VERIFIED (real bucket: human item 2) |
+| Read the API docs | `/api-docs` and `/api-docs.json` | `mountAPIDocs`; nonce on all three script tags (`apidocs.go:65-67`), `script-src 'nonce-…'` only (`apidocs.go:208`); `TestAPIDocsCSPNoHostSource` passed | VERIFIED (rendering under CSP: human item 4) |
+| Register behind Turnstile | `turnstile:open|closed` middleware; refusals readable cross-origin | `bouncer.Turnstile`, surf factory; Turnstile 422/503 carry the profile's headers (`TestCORSProfileHeadersOnRefusals/turnstile_*`); boot warning without a secret (`TestTurnstileEmptySecretWarnsAtBoot`) | VERIFIED |
+
+## Goal Achievement
+
+### Observable Truths (roadmap success criteria)
+
+| # | Truth | Status | Evidence |
+|---|-------|--------|----------|
+| SC-1 | `bouncer` refresh issues a new httpOnly `token` cookie with configurable `Domain`/`SameSite`/`Secure`, blacklists the old JTI; 60-min TTL and 14-day refresh window are config keys; credentialed CORS for a configured SPA origin is available as middleware | ✓ VERIFIED | Cookie half unchanged from the initial run and still green. CORS half: global `http.cors` (initial run) and now `cors:<profile>` decorate every response of the route; verifier probe 11/11 on HEAD, 7/11 FAIL on the pre-fix tree; credentialed wildcard/unanchored origins refused at boot (`TestCORSCredentialedOriginRules`, `TestCORSAnchoredPatternNoSuffixMatch`) |
+| SC-2 | Cache module with memory and Redis drivers; Redis-backed `Store` so rate limits hold across instances; Redis client decision note before code | ✓ VERIFIED | Unchanged since the initial run; cooler suites and `TestRateLimitParityDocker`, `TestRedisCacheDocker` passed in the gate; `TestRateLimitAcrossInstancesSmoke` passed separately |
+| SC-3 | S3 blob driver selectable through framework config without the app importing it; `/api-docs` + `/api-docs.json` servable; Turnstile middleware available | ✓ VERIFIED | Unchanged artifacts plus plan 06 hardening (WR-06, WR-07, WR-08), each pinned by a required test that passed in the gate (attach tests ran untagged and with `-tags summercms_s3`) |
+| SC-4 | Touched modules' READMEs and `docs/` updated; new code has unit tests in the last plan | ✓ VERIFIED | Plan 06 updated the surf, bouncer, lagoon and cooler READMEs and `docs/services/{routing,authentication,storage,caching}.md`, `docs/architecture/request-lifecycle.md`; `TestDocsTree` and `docs:build --check` passed in the gate's docs stage. Plan 06 commits its tests in `8d80580` (Task 6) after the fix commits, so the "unit tests last" rule holds for the gap-closure plan |
+
+**Score:** 4/4 roadmap truths verified. Plan must-haves 44/44 verified (0 present-but-behavior-unverified).

+|---|------------------|--------|----------|
+| 1 | CR-01: every response of a `cors:<profile>` route carries ACAO (exact origin), ACAC, `Vary: Origin` for 401/403 (route-before or group), 422/503 Turnstile, 429, 413, panic 500 (JSON and raw); disallowed origin gets `Vary: Origin` only; handler `Vary` merged | ✓ VERIFIED | Verifier probe 11/11 (real HTTP server via `httptest.NewServer`); `TestCORSProfileHeadersOnRefusals` (11 subtests incl. Turnstile 422/503, 403) and `TestCORSProfileVaryKeptWithHandlerVary` passed in the gate |
+| 2 | CR-01 gate and docs | ✓ VERIFIED | `scripts/check-phase19.3.sh:80` lists both tests in `SURF_TESTS`; docs lines cited above |
+| 3 | D-04 / WR-04: credentialed wildcard-host, unanchored and probe-matching origins fail boot, globally and per profile; non-credentialed configs unchanged | ✓ VERIFIED | `cors.go` `wildcardHostLabel`, `anchoredOriginPattern` (parsed with `regexp/syntax`), `corsProbeOrigins`; `TestCORSCredentialedOriginRules`, `TestCORSAnchoredPatternNoSuffixMatch`, `TestCORSOptionsMatchesLaravel`, `TestCORSStarUnchanged` passed. Verifier probe: `https://*.com`, `https://*`, `https://*example.com` refused, `https://*.example.com` loads. Residual: see Advisory |
+| 4 | D-03 / WR-05, WR-09: production refuses Secure resolving to false (set or inferred); zero `CookieConfig` writes Lax + Secure | ✓ VERIFIED | `cookie.go:111` error names `auth.cookie.secure` and `app.url`; `TestLoadCookieConfigProductionInferredSecure`, `TestZeroCookieConfigDefaults`, `TestLoadCookieConfigErrors` passed |
+| 5 | D-17, D-12, D-18 / WR-06, WR-07, WR-08 | ✓ VERIFIED | `apidocs.go:65-67,208`; `attach/store.go:42,136` returns `ErrProtectedNeedsPrivateBucket` after the argument checks, before the body is read; boot warning in `bucket.go`; Turnstile secret warning in `BuildRouter`; `TestAPIDocsCSPNoHostSource`, `TestStoreProtectedNeedsPrivateBucket` (both tag modes), `TestTurnstileEmptySecretWarnsAtBoot` passed |

Plugin commits change only test files (`git show --stat`) |
+| 7 | D-11 / WR-03: layer purge route honours `siteCache.allowProxied`; shared files byte-identical with updated pins; caching docs pair remote https `purge_url` with the flag | ✓ VERIFIED | `purge.post.ts` passes `allowProxied` (`=== true` or `'true'`) to `authorizeSitePurge`; sha256 of the shared files is identical in vue-faq-layer, vue-menu-layer, vue-journal-layer; layer TAP 24/37/170 pass, including "allowProxied lets a proxied request reach the token check" |
+| 8 | Release precondition: gate `--all` green with Docker and names every new test; disposition records CR-01, WR-01..WR-09 fixed; nothing tagged or pushed before the human reply | ✓ VERIFIED | Gate exit 0 (below). 19.3-REVIEW-DISPOSITION.md: 10 fixed, 11 info open. `git tag --contains 0723536` empty; summercms.go 22 commits ahead of `origin/master`, no `v0.1.28` on origin; plugins and layers each 1 commit ahead of origin with no tag on HEAD |

+
+Artifacts from plans 01-05: unchanged status (✓ VERIFIED; `cors.go` upgraded from ⚠️ PARTIAL).
+
+### Key Link Verification (plan 06)
+
+| From | To | Via | Status |
+|------|----|-----|--------|
+| `surf/router.go` wrap | `surf/cors.go` | `routeCORSProfile(rt)` then `r.corsProfiles[profile].profileMiddleware(h)` after recovery, inside `recordPattern` | WIRED (probe confirms runtime effect) |
+| `scripts/check-phase19.3.sh` | `surf/cors_profile_test.go` | `SURF_TESTS` names `TestCORSProfileHeadersOnRefusals` | WIRED (ran in the go stage: 29 surf tests passed) |
+| `cooler/sitecache.go` | `lagoon.AfterCommit` | `PurgeSiteCacheAfterCommit` callback only calls `p.enqueue` | WIRED |
+| `cooler/cooler.go` | `cooler/sitecache.go` | `Handle.Close` → `h.purger.Wait(ctx)` | WIRED |
+| layer `purge.post.ts` | layer `siteCachePurge.ts` | `authorizeSitePurge({..., allowProxied})` | WIRED |
+
+Key links from plans 01-05: unchanged, WIRED.
+
+### Data-Flow Trace (Level 4)
+
+Not applicable: no rendered dynamic data. The runtime flows (cookie → Refresh → blacklist; request → throttle → shared Redis counter; save → after-commit → queued purge POST; refusal → profile CORS headers) are each exercised by a passing test or the verifier probe.
+
+### Behavioral Spot-Checks
+
+| Behavior | Command | Result | Status |
+|----------|---------|--------|--------|
+| Phase gate, all stages, Docker required | `PHASE193_REQUIRE_DOCKER=1 bash scripts/check-phase19.3.sh --all` | exit 0; PASS self-test, go, plugins, layers, docs, docker ("Phase 19.3 gate passed") | ✓ PASS |

+### Probe Execution
+
+No `scripts/*/tests/probe-*.sh` exist and no plan declares one. The phase gate was run by the verifier in its own process (above).
+
+### Requirements Coverage

+
+### Prohibitions (all judgment-tier; non-authoritative verifier verdicts)
+
+Plans 01-05: verdicts from the initial run still hold (cooler imports, bouncer imports, Flush scope, byte-identical `*` CORS, Turnstile secret never logged, no new `s3.*` keys, Journal/menu/FAQ compatibility, test network scope).
+
+| Plan | Prohibition | Verdict | Evidence |
+|------|-------------|---------|----------|
+| 06 | No breaking change to Journal, menu, FAQ: exported cooler purge names/signatures, Journal aliases, plugin controllers unchanged; only plugin test files change | holds | plugin commits `e52b286`, `4b42978`, `4f633f0` touch only `*_test.go`; `PurgeSiteCacheAfterCommit` and `SiteCachePurger.Purge` keep their signatures (`Wait` is additive); Journal alias tests passed. Note: the plugin tests now call `SiteCachePurger.Wait`, so the plugins need the v0.1.28 require bump before they build on origin without go.work (recorded in the SUMMARY handoff) |
+| 06 | Non-credentialed `*` CORS byte-identical | holds | `TestCORSOptionsMatchesLaravel`, `TestCORSStarUnchanged` passed |
+| 06 | Framework code and docs never name a consuming application | holds | gate docs stage: "no consuming application named in framework lines since 2d352ff^" |
+| 06 | Nothing pushed or tagged before the human's reply | holds | no tag contains `0723536`; no `v0.1.28` on origin; plugins and layers 1 commit ahead with untagged HEADs |

+
+### Anti-Patterns Found
+
+No `TBD`/`FIXME`/`XXX`/`TODO`/`HACK` markers in files changed by plan 06 (the only match is the gate's TAP `SKIP|TODO` directive parser at `scripts/check-phase19.3.sh:261`). No stubs: every plan 06 change is exercised by a named test that ran.

+
+### Advisory (New Scope, Unevidenced)
+
+| # | Finding | Category | Why Advisory |
+|---|---------|----------|--------------|
+| 1 | Credentialed wildcard on a multi-label public suffix (`https://*.co.uk`) passes boot validation | security | new scope relative to the carried-forward gap; only scratch-probe evidence; plan 06's contract (probe origins, `https://*.com`) holds |
+
+### Human Verification Required
+
+1. **Cookie refresh across real subdomains.** Deploy to staging with `auth.cookie.domain` set to the parent domain and `cors:<profile>` (or `http.cors`) credentialed for the www origin. Log in on www and wait past the access TTL.
+   - Expected: the SPA reads the 401, the refresh call sends the cookie, the rotated cookie replaces it.
+   - Why human: needs real DNS and TLS, and a browser's cookie and CORS enforcement.
+2. **Real S3/R2/MinIO upload.** Build with `build.tags: [summercms_s3]`, set `bucket_url: s3://...?endpoint=...`, upload, fetch via `public_url` and via `/storage/uploads`; try a protected upload with `public_url` set.
+   - Expected: both URLs serve the public file; the protected upload is refused.
+   - Why human: needs bucket credentials.
+3. **Live Nuxt purge.** Save a menu entry and a FAQ entry in admin against a site on the new layer versions (set `NUXT_SITE_CACHE_ALLOW_PROXIED=true` behind a proxy).
+   - Expected: the page updates without waiting for the 300 s SWR TTL; the purge is logged after the save returned.
+   - Why human: needs a running Nuxt site and the app.
+4. **Swagger UI under the nonce-only CSP.** Enable `http.api_docs`, open `/api-docs`.
+   - Expected: the UI renders the spec with no CSP violations in the console.
+   - Why human: browser rendering; WR-06 tightened `script-src` since the initial verification.
+
+The initial report's item 5 (triage WR-01..WR-09) is settled: all ten CR/WR findings are `fixed` in 19.3-REVIEW-DISPOSITION.md.
+
+### Gaps Summary
+
+No gaps. The one gap from the initial verification (SC-1 / D-05, CR-01) is closed in code, docs and gate. The verifier reproduced the earlier failure scenarios in a scratch module outside the repo: every case now carries the profile's headers on HEAD, and the same probe still fails on the pre-fix tree, so it actually tests the fix. The full gate passes with Docker required, and the earlier must-haves show no regression. The status is `human_needed` because four checks need real infrastructure or a browser. The release steps in the 19.3-06 SUMMARY handoff remain for the phase session: whole-phase docs, the v0.1.28 tag, the plugin require bumps and the layer tags. Until the plugins move to v0.1.28, their tests do not build on origin without go.work.

+# API Coverage — Cloudflare Turnstile siteverify, Redis (go-redis v9), S3 (gocloud s3blob)
+
+> Full coverage by default. Opt-outs are explicit, reasoned decisions.
+
+Scope: the three external services phase 19.3 integrates. Turnstile siteverify is called by `bouncer.Turnstile` (plan 19.3-02, D-18) with the PHP `TurnstileVerifier` semantics as the contract. Redis is reached through go-redis v9.23.0 from `cooler` (plan 19.3-01, D-07..D-09). S3 and S3-compatible stores are reached through `gocloud.dev/blob/s3blob` behind the `summercms_s3` build tag (plan 19.3-03, D-13, D-14). Capability names carry the service as a prefix so they stay unique in one matrix.
+
+| capability | decision | reason |
+|---|---|---|
+| turnstile: siteverify POST as form fields secret and response | INTEGRATE | same transport as PHP (Http::asForm) |
+| turnstile: remoteip field from the trusted client IP | INTEGRATE | surf.ClientIP with http.trusted_proxies, as PHP passes $request->ip() |
+| turnstile: 5 s request timeout, context-aware | INTEGRATE | D-18; applied to both modes |
+| turnstile: read success from the answer (success === true) | INTEGRATE | |
+| turnstile: error-codes read for the log line (never the token or secret) | INTEGRATE | diagnostics only; the verdict stays success-based |
+| turnstile: fail-open mode (empty secret passes) | INTEGRATE | D-18 registration path |
+| turnstile: fail-closed mode (503 unconfigured in production, 422 on missing token, false, error or timeout) | INTEGRATE | D-18 guest entry path |
+| turnstile: reject a token longer than 2048 characters without a call | INTEGRATE | Cloudflare's documented token limit; saves a siteverify call |
+| turnstile: idempotency_key for retried verification | OPT-OUT | the verifier makes exactly one attempt per request and never retries, so there is nothing to deduplicate |
+| turnstile: hostname check of the answer | OPT-OUT | not in the PHP contract; the site key is bound to its hostnames in the Cloudflare dashboard |
+| turnstile: action check of the answer | OPT-OUT | not in the PHP contract; the widgets of the ported clients set no action |
+| turnstile: cdata and challenge_ts fields | OPT-OUT | not in the PHP contract; tokens are single-use and expire after 300 s on Cloudflare's side |
+| turnstile: JSON request body instead of form | OPT-OUT | form encoding is what PHP sends; Cloudflare accepts both |
+| redis: connection from redis.url (redis://, rediss:// TLS, unix://, ACL user and password in the URL) | INTEGRATE | go-redis ParseURL; the URL never appears in an error or log |
+| redis: client handshake without CLIENT SETINFO and without maintenance notifications | INTEGRATE | DisableIdentity and maintnotifications ModeDisabled (RESEARCH Pitfall 14) |
+| redis: PING at serve start-up with a 3 s timeout | INTEGRATE | an unreachable server is a warning, never a boot failure (user answer: memory fallback) |
+| redis: GET, SET with PX, EXISTS, UNLINK, INCRBY for the cache | INTEGRATE | D-08 Get, Set, Has, Forget, Increment |
+| redis: SCAN MATCH under the cache prefix plus UNLINK for Flush | INTEGRATE | Flush never empties the whole database (rate-limit counters and other apps share it) |
+| redis: EVALSHA with EVAL fallback for the fixed-window rate-limit script | INTEGRATE | go-redis NewScript and Run; probed on Redis 7.2.5 |
+| redis: Sentinel and Cluster clients | OPT-OUT | not needed yet: one redis.url names one server; a later phase adds them if a deployment needs them |
+| redis: pub/sub, streams and locks | OPT-OUT | explicitly out of scope: D-08 excludes tags and locks until a ported plugin needs them |
+| redis: Redis-backed bouncer.BlacklistStore | OPT-OUT | deferred in CONTEXT (optional, not required by the success criteria) |
+| s3: open s3://bucket through gocloud URL query (region, endpoint, use_path_style, disable_https) | INTEGRATE | D-14; no parallel s3.* key set |
+| s3: request_checksum_calculation and response_checksum_validation query parameters | INTEGRATE | passed through gocloud for S3-compatible stores (R2, MinIO, Hetzner); documented |
+| s3: credentials from the standard AWS environment and shared config (profile, role) | INTEGRATE | D-14; never in summer config |
+| s3: server-side encryption (ssetype, kmskeyid) and accelerate, dualstack, fips | INTEGRATE | native gocloud URL parameters; no framework code, documented only |
+| s3: object write, read, delete and list through blob.Bucket | INTEGRATE | the existing attach paths (Store, StaticHandler, DeleteKeys) run unchanged on the s3 driver |
+| s3: public object URLs through storage.uploads.public_url | INTEGRATE | D-12 |
+| s3: presigned GET URLs | OPT-OUT | not needed: public files use public_url or the /storage/uploads proxy route (D-12) |
+| s3: bucket creation and lifecycle or CORS configuration | OPT-OUT | operator-managed outside the application |

+# Phase 19.3 deferred items
+
+Out-of-scope findings logged by executors. Not fixed in the plan that found them.
+
+## From 19.3-03
+
+- `internal/build/registry.go` is not gofmt-clean (const block alignment, `registryFileName` / `generatedMark`). Pre-existing, untouched by 19.3-03; `go vet` is unaffected.
+- The 19.3-03 Task 3 acceptance grep `grep -rniE 'wavepath|fonoteka|grzyby' modules/lagoon ...` matches pre-existing test files outside the plan's scope: `modules/lagoon/hidden_marshal_test.go` (comments naming the consumer app), `modules/lagoon/migrations_test.go` (`golem15.fonoteka` as a sample plugin ID) and `modules/lagoon/attach/lifecycle_test.go` (`Golem15\Fonoteka\Models\Album` morph type). CLAUDE.md says framework code never names a consuming application; a follow-up quick task could switch these to neutral names (`acme`). 19.3-03 added no such names.
+
+## From 19.3-04
+
+- Pre-existing gofmt findings (missing trailing newlines), untouched by 19.3-04: `modules/cabana/account_tokens.go`, `modules/cabana/account_tokens_test.go`, `modules/cabana/token_postgres_smoke_test.go`, `modules/cabana/token_routes_test.go`, `modules/cabana/token_scopes_test.go`, and in the Journal plugin `classes/blog_editor_test.go`. `go vet` and the suites are unaffected.
+- Deployment follow-up: move the grzybyfunkcjonalne deployment from `golem15.journal.site_cache.*` and `NUXT_JOURNAL_CACHE_PURGE_TOKEN` to `site_cache.purge_url`/`site_cache.purge_token` and `NUXT_SITE_CACHE_PURGE_TOKEN` (route `/api/__site__/cache/purge`) before the Journal alias keys are removed.
+- `sm-summercmsio-app` mounts the Journal plugin 45 commits behind main; bump its pointer in a separate follow-up.
+
+## From 19.3-05
+
+- Security observation (not a test failure; plan 03 kept the stored `content_type` rule by design): `attach.Store` writes the blob with the sniffed content type as object metadata, so an HTML body uploaded as `note.txt` is stored as `<id>.txt` with `Content-Type: text/html`, and a generic sniff takes the type from the extension (`app.js` with binary bytes is stored as `.bin` with `text/javascript`). The surf uploads route neutralises this (nosniff, sandbox CSP, attachment disposition), but with `storage.uploads.public_url` pointing at an S3 bucket the bucket serves the object's stored Content-Type directly, so such a file renders as HTML on the bucket or CDN host. `docs/services/storage.md`'s deploy note says a CDN "picks the Content-Type from the file extension", which is not true for S3 object metadata. A follow-up could write a non-rendering content type (or `Content-Disposition: attachment`) for non-inline types to the blob metadata, and correct the deploy note. Pinned by `TestStoreDiskExtension` rows "html named txt" and "js under octet-stream".
+- Redis outage latency (follow-up from 19.3-01 now pinned by tests): `TestRateLimitFallbackOnError` asserts a rate-limit attempt against a stopped Redis answers from the fallback within `AttemptTimeout` (about 500 ms per throttled request during an outage). `Cache.Remember` on the Redis driver has no internal bound: against a stopped Redis it waits for go-redis's dial retries (about 1.7 s, five dial attempts) unless the caller's context has a deadline, and go-redis logs `failed to dial after 5 attempts` to stderr on every failing call, outside slog and the once-per-minute warner. A follow-up could bound Remember's read and write (as Attempt does), lower `MaxRetries`/dial timeout in `OpenRedis`, and route go-redis's logger through slog.
+- Coverage note: the plugins' `purgeSiteCache` branch "inside a save transaction but no purger configured" cannot be reached from a unit test, because cabana has no exported way to put a transaction in a context (`withTx` is internal). The plugins' Docker admin suites run every save through it without purge keys; a test-only helper in cabana (like `cabana.WithFieldWrites`) would let a unit test reach it.

+<objective>
+Bring the framework docs up to date with everything shipped since the docs summercms.io last embedded (framework v0.1.14), add the "Upgrading to 0.2" notes required by decision note `.planning/notes/2026-10-15-release-v0-2-0.md` (commit 76d7888), release framework **v0.2.0** with the plugin requires and layer tags handed off by 19.3-06, then rebuild summercms.io against v0.2.0 and deploy it so `/docs` shows the new pages.
+
+Purpose: summercms.io/docs is 13 framework tags behind (it embeds v0.1.14 docs), and 19.3's gap closure changed boot behaviour, which is why the release is v0.2.0 and why upgrade notes ship with it.
+Output: updated docs/ (one new page), tag v0.2.0, three plugin require bumps, three layer tags, summercms.io on v0.2.0 built, pushed and deployed (or a checkpoint for the server step).
+
+Release decision (user, this session): version **v0.2.0**, not v0.1.28. Layer tags stay v0.3.0 / v0.3.0 / v0.5.0. Out of scope: moving sm-grzybyfunkcjonalne-app's layer pins or plugin submodule pointers, moving the summercms.io app's user/translate/journal submodule pointers (planning-time `go build` of the app against current master succeeded with the existing pins), and `/msd-verify-work 19.3`.
+
+Shape: no tracer task. This is a strictly ordered release pipeline (docs, then tag, then consumers, then deploy) with an immutable tag in the middle, so a thin end-to-end slice adds no information. Task 1's verify does render the docs exactly as summercms.io's build does (`--base-url /docs --site-url / --site-label summercms.io`), which proves the docs end of the path before anything is tagged.
+
+Repo hygiene for all tasks: stage files by explicit path, never `git add -A`; leave other sessions' uncommitted files alone (`.planning/state.json`, `.msd/`, `.planning/phases/17-blog-companions/17-VERIFICATION.md` in summercms.go); no Co-Authored-By or other co-author trailers in any commit or tag message (user's global instruction overrides the default attribution); never force-push; before every push run `git fetch origin --tags` and confirm the branch is not behind (`git rev-list --count HEAD..origin/<branch>` is 0). If a branch is behind, stop and report rather than rebase across other sessions' work.

+
+Planning-time observations (live, 2026-10-15):
+- summercms.go master is 24 commits ahead of origin/master, highest tag v0.1.27, `v0.2.0` free on origin. `go test ./cmd/summer -run TestDocsTree` passes on HEAD. `summer` is not on PATH: use `go run ./cmd/summer ...` from the framework root.
+- Phases with framework code since v0.1.14: 14.2 (access log, uploads serving), 16.2 (plugin-provided field types), 16.3 (admin personal API tokens, `admin:token:*`), 17 (signpost menu item types, seaglass sanitizer, richeditor, repeater, reorder, singleton), 18 (money and password fields, settings secrets, record actions), 18.1 (taglist, reorder tree), 19.3 (cooler caches and Redis rate-limit store, site-cache purge, `pact.ReorderAfterSave`, bouncer token cookies and Turnstile, credentialed CORS and `cors:<profile>`, `/api-docs`, `summer.yaml` `build.tags` and `summercms_s3`, `storage.uploads.public_url`), quick 261011-joh (sieve). Each of these already updated its own service/backend pages and module README; the API reference section is generated from every `modules/*/README.md`, so new modules appear there automatically; the root README module table already lists all 28 modules.
+- Gaps found on the hub pages (Task 1 fixes these, then runs its own pass for anything else):
+  1. `docs/architecture/introduction.md` "The framework modules" table lists 24 of 28 modules: missing cooler, seaglass, signpost, sunrise.
+  2. `docs/setup/coming-from-wintercms.md` "not provided" table still says the Reorder behaviour (record sorting) and Cache are not provided; both shipped. The concept map has no rows for Cache, menu item types, form widgets / plugin field types, HTML sanitizing, singleton settings models, personal API tokens, captcha, credentialed CORS.
+  3. `docs/setup/configuration.md` "Keys an application sets" has no rows for `http.cors_profiles.*`, `http.api_docs.*` (`enabled`, `path`, `title`), `auth.cookie.*` (`name`, `domain`, `path`, `secure`, `same_site`) or `turnstile.secret` / `turnstile.field`; those keys are documented only on routing.md and authentication.md.
+  4. `docs/index.md` "Where to start" does not mention caching, field types, API tokens or menu item types; `docs/setup/introduction.md` "How these docs are organised" omits the Backend, Database and Services sections.
+  5. `docs/services/frontend-and-ajax.md` "Building the frontend" predates the cookie refresh/logout handlers, `cors:<profile>`, Turnstile, the site-cache purge and `/api-docs`.
+  6. There is no upgrade page; `docs/setup/installation.md#updating-an-application` covers the update script only.
+- Setup page orders: introduction 10, installation 20, configuration 30, coming-from-wintercms 40, porting-a-plugin 50. Sidebar order comes from frontmatter `order`; `docs/site.yaml` lists sections only.
+- Anchors that exist for linking: `services/routing.md#cors`, `#cors-profiles`, `#api-documentation-page`; `services/authentication.md#cookie-transport`, `#turnstile`; `setup/installation.md#updating-an-application`.
+- The Journal plugin's deprecated keys are `golem15.journal.site_cache.purge_url` and `golem15.journal.site_cache.purge_token` (framework keys `site_cache.purge_url` / `site_cache.purge_token` win; a deprecation warning is logged).
+- Plugins: sm-faq-plugin, sm-menu-plugin, sm-journal-plugin each 1 commit ahead of origin/main, require summercms v0.1.27, have a local go.work (hence GOWORK=off). Layers: vue-faq-layer and vue-menu-layer package.json 0.3.0 (origin tags up to v0.2.0), vue-journal-layer 0.5.0 (origin tags up to v0.4.0), each 1 commit ahead of origin/main. Prior tag style: `v0.1.27: <one-line summary> (Phase 19.3)`; layer `v0.4.0: <one-line summary>`.
+- `go env`: GOPROXY=https://proxy.golang.org,direct, GOPRIVATE empty. The framework repo is public, so the proxy fetches a fresh tag on demand; if `go get ...@v0.2.0` reports an unknown revision right after the push, retry once with `GOPROXY=direct`.
+- summercms.io app: clean, not ahead; go.mod and the site plugin (`plugins/golem15/summercms`, repo sm-summercmsio-plugin, branch master) require v0.1.14; app go.work replaces the framework with ../summercms.go. The previous bump (app commit 83c005d "chore: build against summercms v0.1.14", plugin commit 3845d8c "chore: require summercms v0.1.14") touched app go.mod, CLAUDE.md, DEPLOY.md, README.md and the plugin gitlink. `scripts/build.sh` header comment still says v0.1.12. App config has no `auth.cookie` block and no CORS config, so the v0.2.0 boot refusals do not apply to it; `scripts/smoke.sh` proves the boot.
+- rome: `ssh rome` does not resolve from this machine (no `~/.ssh/config` alias, not in /etc/hosts). https://summercms.io/docs/ answers 200 (live site, so this is a normal redeploy: DEPLOY.md "Build (local)", "Upload", "Release (every deploy)", then the verify list; skip "First release only", "Cutover" and the launch checklist).
+- g15office: Phase 19.3 milestone task id `lpybyjdh` (`.planning/G15OFFICE.md`); no g15office CLI on PATH.

+Work in the framework root (/media/nvme/dev/golem15/summercms.io/summercms/summercms.go). Read each page before editing it and match its existing voice: plain declarative sentences, tables with a "Where"/module-link column, links relative within docs/ and to `../../modules/<name>/README.md`. Every identifier written into docs must exist in the package (the checker enforces it); config keys are not checked automatically, so copy each key from the page or README that already documents it (routing.md, authentication.md, caching.md, storage.md, the cooler/surf/bouncer/lagoon READMEs). Never name a consuming application anywhere in docs (core plugins such as the Journal, menu and FAQ plugins may be named, as caching.md already does); the verify step greps for the known names.
+
+1. New page `docs/setup/upgrading.md`, per decision note 2026-10-15-release-v0-2-0. Frontmatter: title "Upgrading", a description under 160 characters, section setup, order 60 (last in Setup, after Porting a plugin). Body:
+   - A short intro: how to move an application to a newer framework release (link `installation.md#updating-an-application` for the update script; for a module require, `go get git.golem15.com/golem15/summercms@v0.2.0` then `go mod tidy`), and the versioning rule from the decision note: the minor version is bumped when an upgrade can refuse a previously valid config or changes a documented behaviour; patch versions are safe to take without reading.
+   - `## Upgrading to 0.2` with `### Boot refusals` covering exactly two items, each with the symptom (the start-up error and the key it names), who is affected and the fix:
+     (a) WR-05: in the production environment, `bouncer.LoadCookieConfig` refuses a token cookie whose Secure resolves to false, whether set to false or inferred from an http or unset `app.url`. Affects applications that load an `auth.cookie` block. Fix: set `app.url` to the https URL, or set `auth.cookie.secure` explicitly. Link `../services/authentication.md#cookie-transport`.
+     (b) WR-04: with `supports_credentials: true`, globally under `http.cors` or in any `http.cors_profiles.<name>`, wildcard `allowed_origins` entries other than a whole leftmost host label and `allowed_origins_patterns` entries not anchored with `^` and `$` (every alternative) fail the start-up, naming the key and index. Fix: list exact origins, or anchored patterns such as the one routing.md shows. Link `../services/routing.md#cors` and `#cors-profiles`.
+   - `### Behaviour changes`: WR-01 site-cache purges after an admin save are queued after commit and coalesced (one request in flight per purger); tests that assert a purge call `cooler.SiteCachePurger.Wait` first, and shutdown drains the queue (link caching.md). WR-07 an upload with `is_public` false is refused with `attach.ErrProtectedNeedsPrivateBucket` while `storage.uploads.public_url` is set, and `attach.OpenBucket` warns at boot (link storage.md or database/attachments.md, whichever documents public_url). The Journal plugin's `golem15.journal.site_cache.purge_url` and `golem15.journal.site_cache.purge_token` are deprecated aliases of `site_cache.purge_url` / `site_cache.purge_token`; the framework keys win and a warning is logged. Also one line each for the smaller hardening a reader may notice: the zero `bouncer.CookieConfig` writes SameSite=Lax and Secure (WR-09), `/api-docs` allows only nonce-carrying scripts (WR-06), a boot warning when turnstile routes have no secret (WR-08), `cors:<profile>` headers now on every response of the route including refusals and recovered panics (CR-01).
+   - `## What 0.2 adds since 0.1` (the summercms.io docs last showed the 0.1 series): a bulleted list, one line per feature with a link to its page, covering at least: caching and the Redis rate-limit store, site-cache purge and `pact.ReorderAfterSave` (services/caching.md), token cookies and Turnstile (services/authentication.md), credentialed CORS, CORS profiles and the API documentation page (services/routing.md), `build.tags` and S3 uploads plus `storage.uploads.public_url` (services/storage.md, architecture/go-modules-and-workspaces.md), access log (services/logging.md), plugin-provided field types (backend/field-types.md), richeditor, repeater, money, taglist and dependent fields (backend/forms.md), record reordering and singleton controllers (backend/lists-and-filters.md, backend/settings.md or admin-controllers.md, wherever they are documented), admin personal API tokens and `admin:token:*` (backend/users-and-permissions.md, console/setup-and-maintenance.md), menu item types (plugins/menu-item-types.md), and the new modules cooler, seaglass, sieve, signpost (their README links).
+2. `docs/index.md`: in "Where to start", add Upgrading to the Setup bullet (link `setup/upgrading.md`), caching to the Services bullet, field types and API tokens to the Backend bullet, menu item types to the Plugins bullet. Keep each bullet one sentence-ish line.
+3. `docs/setup/introduction.md` "How these docs are organised": mention upgrading in the Setup bullet and add the missing Backend, Database and Services bullets so the list matches docs/site.yaml's sections.
+4. `docs/architecture/introduction.md` module table: add cooler (Services), seaglass (Admin, the rich text sanitizer), signpost (Plugins and the container, or Services; pick by what its README says it serves) and sunrise (Console and tooling). Afterwards the table links all 28 directories under modules/.
+5. `docs/setup/coming-from-wintercms.md`: replace the two stale rows in the "not provided" table (Reorder behaviour, Cache) by moving them into the concept map as provided features; add concept-map rows for Laravel Cache / `Cache::remember` → cooler (caching.md), the Static Pages menu item types → signpost (plugins/menu-item-types.md), `registerFormWidgets` / form widgets → plugin-provided field types (backend/field-types.md), the Reorder behaviour → reorder (lists-and-filters.md), singleton settings models → singleton controllers (settings.md), HTML cleaning of rich text → seaglass, personal access tokens → admin API tokens (users-and-permissions.md), captcha on public forms → Turnstile (authentication.md#turnstile), and the Laravel CORS config → `http.cors` and CORS profiles (routing.md). Use only identifiers that the module READMEs already document.
+6. `docs/setup/configuration.md` "Keys an application sets": add rows for `http.cors_profiles.*` (named CORS profiles applied with the `cors:<profile>` middleware), `http.api_docs.enabled` / `path` / `title`, `auth.cookie.*`, and `turnstile.secret` / `turnstile.field`, each with its module link; extend the `http.cors.*` row with one clause that credentialed CORS refuses wildcard-host and unanchored patterns at boot; add one sentence after the table pointing to Upgrading for keys whose validation tightened in 0.2.
+7. `docs/services/frontend-and-ajax.md` "Building the frontend": extend Signing in with the httpOnly token cookie and its refresh/logout handlers (authentication.md#cookie-transport); extend Cross-origin calls with `cors:<profile>` for a credentialed SPA (routing.md#cors-profiles); add bullets for bot protection on public forms (Turnstile), purging the frontend's page cache after admin saves (caching.md) and the browsable API documentation page (routing.md#api-documentation-page).
+8. Audit pass (bounded): for each module README changed since v0.1.14 (`git diff --name-only v0.1.14..HEAD -- 'modules/*/README.md'`), skim its Features list and confirm each feature is named on at least one docs/ guide page (grep the docs tree for its key identifier). Fix small gaps in place (a sentence or a table row on the page that owns the topic). List anything larger in the SUMMARY under "Docs gaps left" instead of writing a new guide page.
+9. Run `go run ./cmd/summer docs:sync` only if a `src=` snippet source changed (none is expected). Commit the docs in one commit, staging only the docs files you changed by path: `docs(quick-261015-w7f): docs since v0.1.14 and the Upgrading to 0.2 notes`. No .planning files in this commit.

+  <action>
+Per decision note 2026-10-15-release-v0-2-0 and the 19.3-06 handoff (steps 2-4, with v0.2.0 in place of v0.1.28).
+
+1. Pre-tag gate in the framework root: `go vet ./...`, `go test -short ./...`, `(cd examples/hello && go test ./...)`, and `bash scripts/check-phase19.3.sh --all`. If the Docker daemon is not reachable from this shell, the gate prints NOT RUN docker; per CLAUDE.md retry the docker stage as `sudo -u golem` only if that works without a password, otherwise accept NOT RUN docker (19.3-06 ran it green and only docs changed since) and note it in the SUMMARY. Any other failure: stop, do not tag.
+2. Confirm the tree is ready: `git status --porcelain` shows only the other sessions' files listed in the objective (they are not part of the tag; the tag points at a commit); `git fetch origin --tags`; `git rev-list --count HEAD..origin/master` is 0; `git ls-remote --tags origin v0.2.0` prints nothing.
+3. Write the tag message to a file in the scratch directory (not the repo) and create the annotated tag with `git tag -a v0.2.0 -F <file>` on master HEAD. Message: first line `v0.2.0: <one-line summary of what 19.3 and its gap closure ship>` in the v0.1.27 style; a blank line; an "Upgrading to 0.2" block with the two boot refusals and their fixes (WR-05: production refuses a token cookie whose Secure is inferred false from an http or unset app.url; set app.url to https or auth.cookie.secure explicitly. WR-04: credentialed CORS refuses wildcard-host and unanchored origin patterns, globally and per profile; list exact origins or anchored patterns) and the smaller behaviour changes (queued and coalesced site-cache purge, WR-01; protected uploads refused into a public_url bucket, WR-07; Journal purge keys deprecated in favour of site_cache.*); a closing line pointing to docs/setup/upgrading.md. Never name a consuming application in the message (same rule as docs). No co-author trailer.
+4. Push: `git push origin master`, then `git push origin v0.2.0`. Confirm with `git ls-remote --tags origin v0.2.0` (tag and its peeled line) and `git rev-list --left-right --count origin/master...master` = 0 0.
+5. For each of ../sm-faq-plugin, ../sm-menu-plugin, ../sm-journal-plugin (branch main): `GOWORK=off go get git.golem15.com/golem15/summercms@v0.2.0` (retry once with GOPROXY=direct if the proxy does not know the tag yet), `GOWORK=off go mod tidy`, `GOWORK=off go vet ./...`, `GOWORK=off go test -count=1 ./...` (Docker-backed tests: same Docker note as step 1; if Docker is unavailable run `GOWORK=off go test -count=1 -short ./...` and record that). Commit only go.mod and go.sum by path as `chore: require summercms v0.2.0`. Fetch, check not behind, `git push origin main`. The plugins' tests call `cooler.SiteCachePurger.Wait`, which is why the pushed main only builds standalone after this bump.
+6. Layers ../vue-faq-layer, ../vue-menu-layer, ../vue-journal-layer (branch main): run `bash scripts/check-phase19.3.sh layers` from the framework root once before pushing. For each layer confirm `package.json` version is 0.3.0, 0.3.0, 0.5.0 respectively and `git ls-remote --tags origin v<version>` prints nothing; fetch, check not behind, `git push origin main`, then `git tag -a v<version> -m "v<version>: <one line, in the v0.4.0 style: the purge route accepts proxied requests on siteCache.allowProxied (NUXT_SITE_CACHE_ALLOW_PROXIED)>"` and `git push origin v<version>`.
+7. Do not touch sm-grzybyfunkcjonalne-app (layer pins, plugin pointers) or any other app: follow-up, out of scope.

Leave the user, translate and journal submodule pointers where they are (planning-time compile against current master succeeded); change them only if the release build fails on them, and then say why in the SUMMARY.
+
+1. Site plugin `plugins/golem15/summercms` (repo sm-summercmsio-plugin, branch master): `GOWORK=off go get git.golem15.com/golem15/summercms@v0.2.0`, `GOWORK=off go mod tidy`, `GOWORK=off go vet ./...`, `GOWORK=off go test -count=1 ./...`. Commit go.mod and go.sum by path as `chore: require summercms v0.2.0`. Do not push yet.
+2. App: set the `git.golem15.com/golem15/summercms` require in go.mod to v0.2.0, `GOWORK=off go mod tidy`, `go vet ./... && go test ./...`. Replace v0.1.14 with v0.2.0 in CLAUDE.md, DEPLOY.md (every occurrence: launch-checklist tag check, Build (local), the `go version -m` sentence) and README.md; in scripts/build.sh fix the stale header comment version (v0.1.12) to v0.2.0. Stage by path: go.mod, go.sum, CLAUDE.md, DEPLOY.md, README.md, scripts/build.sh and the `plugins/golem15/summercms` gitlink; commit `chore: build against summercms v0.2.0`.
+3. Release build: `scripts/build.sh` (release mode; it needs tag v0.2.0 in ../summercms.go, created in Task 2, and refuses dirty trees). If `summer build` regenerates main.go or plugins.gen.go, the script stops: commit them by path as `chore: regenerate main.go for summercms v0.2.0` and rerun. Then `go version -m bin/summercms-io` must show the summercms module at v0.2.0. Run `scripts/smoke.sh` (Docker; same Docker note as Task 2) and `scripts/check-deploy.sh`; with the built trees, `SUMMERCMS_REQUIRE_BUILD=1 go -C plugins/golem15/summercms test -count=1 ./...`. Check the built docs: `plugins/golem15/summercms/public/docs/setup/upgrading.html` and `public/docs/api/cooler.html` exist.
+4. Push, submodule first: fetch and not-behind check, `git -C plugins/golem15/summercms push origin master`, then `git push origin master` for the app. vue-summercmsio-app is unchanged; do not push it.
+5. Deploy preflight: `ssh -o BatchMode=yes -o ConnectTimeout=8 rome 'sudo -n true'`. At planning time `rome` did not resolve from this machine. Do not guess a hostname or IP. If the preflight fails for any reason (unresolved host, auth, sudo wants a password), STOP here and return `## CHECKPOINT REACHED` (type human-action) containing: the absolute path of the built binary and its `go version -m` summercms line; the commands copied verbatim from DEPLOY.md sections "Upload" and "Release (every deploy)" (normal redeploy: not "First release only", not "Cutover"), including the ownership check `stat -c '%U:%G %a %n' /srv/summercms-io /srv/summercms-io/bin /srv/summercms-io/config` from "One-time server setup"; and the post-deploy checks of step 7. Resume instruction: after the user reports the release done, run step 7.
+6. If the preflight succeeds: run the DEPLOY.md "Upload" commands from the app root, then over ssh the ownership check and the "Release (every deploy)" commands in order (migrate with the new binary before the restart, keep `.prev`, restart, local curl). If migrate or the restart fails, roll back per DEPLOY.md "Rollback" (App) and report.
+7. Post-deploy verification from this machine: the DEPLOY.md "Verify after cutover" curl list, plus `curl -s -o /dev/null -w '%{http_code}' https://summercms.io/docs/setup/upgrading.html` = 200 (it is 404 before the deploy), `https://summercms.io/docs/services/caching.html` = 200, `https://summercms.io/docs/api/cooler.html` = 200, and `curl -s https://summercms.io/docs/setup/upgrading.html | grep -q 'Upgrading to 0.2'`. Then rerun `SUMMERCMS_CHECK_EXTERNAL=1 go -C plugins/golem15/summercms test -run TestExternalLinks -count=1 -v ./...`.
+8. g15office: if the session has a g15office tool, post a short comment on task `lpybyjdh` (Phase 19.3) saying v0.2.0 is released with upgrade notes, the plugins require it, the layers are tagged and summercms.io/docs serves it; otherwise list the comment as pending in the SUMMARY for the orchestrator.

+| local repos → git.golem15.com | pushes of master, main and tags that other apps and the public module proxy consume |
+| framework tag → Go module proxy | a published version is cached and immutable |
+| build machine → rome | binary and config upload, migrate and restart of the live site |
+| docs → public site | everything in docs/ and the tag message becomes public |

+| T-w7f-02 | Tampering | tag v0.2.0 on a broken tree | high | mitigate | Task 2 step 1 gate (vet, short tests, examples/hello, check-phase19.3.sh --all) before `git tag`; tag must equal origin/master after push |
+| T-w7f-03 | Information disclosure | docs pages and tag annotation | medium | mitigate | Task 1 verify greps docs, root and module READMEs for consuming-application names (must be 0); `check-phase19.3.sh docs` repeats the check; no secrets or hostnames in docs or the tag message |
+| T-w7f-04 | Denial of service | summercms.io boot after the upgrade (WR-04/WR-05 boot refusals, new required keys) | high | mitigate | app config has no auth.cookie block and no credentialed CORS (observed); `scripts/smoke.sh` boots the release binary on postgres:15 before any upload; DEPLOY.md keeps `bin/summercms-io.prev` and migrate runs before the restart; Rollback (App) on failure |
+| T-w7f-05 | Tampering | deploying a binary not built from pushed commits | medium | mitigate | `scripts/build.sh` release mode refuses dirty trees and compiles against the tag export; `go version -m` must show v0.2.0; push happens before upload |
+| T-w7f-06 | Spoofing / Elevation | rome access | medium | mitigate | no hostname guessing; BatchMode preflight with `sudo -n`; otherwise a human-action checkpoint; `.env` is never rsynced (DEPLOY.md); ownership check of /srv/summercms-io before the release steps |
+| T-w7f-SC | Tampering | `go get` / `go mod tidy` / `pnpm install --frozen-lockfile` | low | accept | only the first-party framework module changes version; its third-party deps are the decided set in .planning/research/STACK.md; pnpm runs from the committed lockfile; no new third-party package is introduced, so no legitimacy checkpoint is needed |

+# Quick 261015-w7f: framework docs since v0.1.14, release v0.2.0, summercms.io on v0.2.0 Summary
+
+Docs gained an "Upgrading to 0.2" page plus hub-page fixes (28-module table, WinterCMS map, config keys), v0.2.0 is tagged and pushed with the three plugin bumps and three layer tags, and a v0.2.0 release build of summercms.io is pushed and smoke-tested. **The rome deploy is not done**: `rome` does not resolve from this machine, so the server step is handed back as a human-action checkpoint below.
+
+## Commits and tags per repo
+
+| Repo | Commit / tag | What |
+|------|--------------|------|
+| summercms.go | `f3e8a98` | docs(quick-261015-w7f): docs since v0.1.14 and the Upgrading to 0.2 notes |
+| summercms.go | tag `v0.2.0` (tag object `d5f754a`, points at `f3e8a98`) | annotated, upgrade notes in the message; pushed with master (`f80e2e8..f3e8a98`, origin/master == master) |
+| sm-faq-plugin | `2efe351` | chore: require summercms v0.2.0 (pushed main, `fa90e83..2efe351`) |
+| sm-menu-plugin | `f7eddd5` | chore: require summercms v0.2.0 (pushed main, `fe27b9a..f7eddd5`) |
+| sm-journal-plugin | `8de4928` | chore: require summercms v0.2.0 (pushed main, `a99e9a1..8de4928`) |
+| vue-faq-layer | tag `v0.3.0` (`225870a`) | main pushed `96b6bc0..a229f6a`, then tagged |
+| vue-menu-layer | tag `v0.3.0` (`255c0fd`) | main pushed `dd0ee35..c4639c2`, then tagged |
+| vue-journal-layer | tag `v0.5.0` (`4673d8e`) | main pushed `5936f66..f5d7aac`, then tagged |
+| sm-summercmsio-plugin (submodule `plugins/golem15/summercms`) | `aac8931` | chore: require summercms v0.2.0 (pushed master, `3845d8c..aac8931`) |
+| sm-summercmsio-app | `36c3c50` | chore: build against summercms v0.2.0 (pushed master, `83c005d..36c3c50`) |
+
+No force-push, no co-author trailers, files staged by path. Plugin bumps changed go.mod only (each plugin's go.mod carries a `replace` to `../summercms.go`, so go.sum has no framework line). Other sessions' files untouched (`.planning/state.json`, `.msd/`, `17-VERIFICATION.md`, `sm-journal-plugin/go.work.sum`).
+
+## Task 1: docs
+
+- New `docs/setup/upgrading.md` (Setup, order 60): update paths (script and `go get ...@v0.2.0`), the version rule from the decision note, `## Upgrading to 0.2` with `### Boot refusals` (token cookie not Secure in production; credentialed CORS with wildcard-host / unanchored / over-broad origin rules, global and per profile) and their fixes, `### Behaviour changes` (queued and coalesced purge with `cooler.SiteCachePurger.Wait`, `attach.ErrProtectedNeedsPrivateBucket`, deprecated Journal purge keys, cookie defaults, api-docs nonce, Turnstile warning, CORS profile headers on every answer), and `## What 0.2 adds since 0.1` with links.
+- `docs/architecture/introduction.md`: cooler, seaglass, signpost, sunrise added; all 28 modules linked.
+- `docs/setup/coming-from-wintercms.md`: "Cache" and "Reorder behaviour" removed from Not provided; nine concept-map rows added (reorder, form widgets / field types, rich text sanitizing, singleton controllers, API tokens, Cache facade, CORS config, captcha / Turnstile, Static Pages menu item events).
+- `docs/setup/configuration.md`: rows for `http.cors_profiles.*`, `http.api_docs.*`, `auth.cookie.*`, `turnstile.*`; credentialed-CORS clause on `http.cors.*`; pointer to Upgrading.
+- `docs/index.md`, `docs/setup/introduction.md`, `docs/services/frontend-and-ajax.md`: links to upgrading, caching, field types, API tokens, menu item types, cookie refresh/logout handlers, CORS profiles, Turnstile, site-cache purge, `/api-docs`.
+- Verify: TASK1_OK (TestDocsTree, `docs:build --check`, summercms.io-style render with `setup/upgrading.html`, name grep 0, `check-phase19.3.sh docs`).
+
+### Docs gaps left
+
+Bounded audit (README Features bullets whose backticked identifiers appear nowhere in docs/): only reference-level details remain, all covered by the generated API reference pages: `backpack.NewRegistry`, `bonfire.NewRootIO`, `bouncer.Middleware`, the cabana `Admin*` swag carriers and seaglass element allowlist, `conga.Daily`/`conga.Every` details, `fetchguard.ReasonScheme`/`ReasonPrivate`, `lighthouse.RegisterDriver`, postcard template naming, `seaglass.Removals`, sunrise truncation safety, `surf.LocaleFromPrincipal` (documented as `locale.from-principal`), `surf.Router.GroupRaw` (documented as `pact.Router.GroupRaw`), tide proxy/rules, towel getters. No guide page needed.
+
+## Task 2: release gate
+
+All gate stages ran green before tagging: `go vet ./...`, `go test -short ./...`, `examples/hello` tests, and `scripts/check-phase19.3.sh --all` with PASS self-test, go, plugins, layers, docs **and docker** (Docker was reachable; nothing NOT RUN). Plugins: `GOWORK=off go vet` and full `GOWORK=off go test -count=1 ./...` (Docker-backed tests included) green for all three.
+
+## Task 3: summercms.io
+
+- Site plugin and app require v0.2.0; v0.1.14 replaced in CLAUDE.md, DEPLOY.md, README.md; build.sh header v0.1.12 -> v0.2.0. User/translate/journal submodule pointers untouched (the build did not need them moved).
+- `scripts/build.sh` (release) succeeded: `build: bin/summercms-io (release v0.2.0) ready`; main.go / plugins.gen.go unchanged by regeneration.
+- `go version -m bin/summercms-io`: `dep git.golem15.com/golem15/summercms v0.2.0`. sha256 `a1c573f96750b08810a76dc3d822d6946e6d2300c791359d5b61de7a0ef81c85`.
+- `scripts/smoke.sh`: `smoke: ok`. `scripts/check-deploy.sh`: ok. `SUMMERCMS_REQUIRE_BUILD=1` plugin tests: ok. Built `public/docs/setup/upgrading.html` and `public/docs/api/cooler.html` exist.
+- TASK3_LOCAL_OK printed. TASK3_DEPLOYED_OK pending: `https://summercms.io/docs/setup/upgrading.html` answers 404 (old binary still live).
+
+## Checkpoint: deploy to rome (human-action, remaining)
+
+Preflight `ssh -o BatchMode=yes -o ConnectTimeout=8 rome 'sudo -n true'` failed: `ssh: Could not resolve hostname rome: Name or service not known` (no alias in ~/.ssh/config or /etc/hosts). No hostname was guessed.
+
+Binary: `/media/nvme/dev/golem15/summercms.io/summercms/sm-summercmsio-app/bin/summercms-io` (`git.golem15.com/golem15/summercms v0.2.0`).

+
+On rome (ownership check from "One-time server setup", must print `root:root 755` three times; then "Release (every deploy)"):

+
+## g15office
+
+Posted by the orchestrator on task `lpybyjdh` (comment 293), status moved to Testing. It says the rome deploy is pending; post a follow-up once it is live.
+
+## Deviations from Plan
+
+- Public upgrading page omits the internal review IDs (WR-01..WR-09, CR-01); the tag message keeps them. Readers of the docs have no use for them.
+- Plugin bumps committed go.mod only (no go.sum change, because of the in-go.mod `replace` to `../summercms.go`); the plan listed go.sum as well.
+
+Otherwise the plan ran as written, up to the planned deploy checkpoint.
+
+## Self-Check: PASSED
+
+- FOUND: docs/setup/upgrading.md
+- FOUND: f3e8a98 (summercms.go), tag v0.2.0 on origin
+- FOUND: 2efe351, f7eddd5, 8de4928 (plugins, pushed)
+- FOUND: aac8931 (site plugin), 36c3c50 (app), both pushed
+- FOUND: layer tags v0.3.0, v0.3.0, v0.5.0 on origin
+- FOUND: bin/summercms-io reporting v0.2.0
+
+## Deploy (orchestrator, 2026-10-16)
+
+Deployed to rome over `ssh -p 2222 debian@10.8.3.118` (the `rome` alias does not resolve on this workstation). Binary sha256 a1c573f9…ef81c85 matched on the server; `migrate` applied; `bin/summercms-io.prev` kept for rollback; supervisor `summercms-io` RUNNING; loopback 200.
+
+Live checks: `/`, `/docs/`, `/docs/setup/upgrading.html` (contains "Upgrading to 0.2"), `/docs/services/caching.html`, `/docs/api/cooler.html`, `/new` all 200; HSTS, www→apex 301, immutable `/_nuxt` assets, docs site link, extensionless 301, `/backend` 404, POST 403, http→https 301 as DEPLOY.md expects. `TestExternalLinks` ok. TASK3_DEPLOYED_OK.
+
+Finding: `/srv/summercms-io/config` is owned by `jin:jin`, not the `root:root` DEPLOY.md expects. Not the service account, so the swap risk DEPLOY.md guards against does not apply, but it should be `sudo chown root:root` to match the documented layout.

+    - 'The top item of the left rail (the Sun mark, now a button with data-theme-toggle) cycles the admin theme system -> light -> dark -> system on click. light never sets the .dark class on <html>, dark always sets it, system follows prefers-color-scheme live (the pre-change behaviour). Its icon and aria-label/title name the current choice in the admin language.'
+    - 'The theme choice is stored server-side for the signed-in admin only: PUT <prefix>/api/v1/account/preferences {"theme": ...} writes backend_users.metadata key admin_theme of the token subject, and GET <prefix>/api/v1/auth/me and GET <prefix>/api/v1/account/preferences return it as preferences.theme ("system" when unset). A second browser signed in as the same admin gets the same theme on load; the SPA applies the last choice from localStorage summer-admin.theme before the first await of boot, so the shell never renders in the wrong theme.'
+    - 'The user menu shows a Language radio group listing every admin locale from GET /lang meta.locales (en and pl in the framework), each named in its own language. Choosing one saves preferences.locale through PUT /account/preferences, caches it in localStorage summer-admin.locale and reloads the page; after the reload the SPA strings (GET /lang?locale=<code>), the navigation, settings, list/form schemas and validation messages are in that language even when the request Accept-Language or a translate-plugin locale cookie names another one.'
+    - 'GET and PUT /account/preferences act only on the row of the authenticated admin (bouncer principal id; no id in the path or body). PUT accepts only the keys theme and locale (any other key, including id or backend_user_id, is a 422 on that key and nothing is written); theme must be one of system, light, dark; locale must be "" (clear) or a code in phrasebook.Translator.Locales("backend::lang."); a value of the wrong type is a 422. Personal API tokens get 403 interactive_only on both routes, and a cookie PUT without X-Requested-With gets 403. Every other metadata key (subtitle, keys copied from WinterCMS) is kept on save, and metadata that is not a JSON object is never overwritten (422).'
+    - 'Requests authenticated with a personal API token keep the request locale exactly as before: the stored admin_locale never becomes their bouncer.Principal.PreferredLocale.'
+    - 'On form, settings form, My account and preview pages the bottom save bar begins at the right edge of the sidebar (the rail, plus the section panel when it is shown), so the Settings rail item at the bottom of the rail stays visible and clickable; list pages are unchanged.'
+    - 'No backend_user_preferences table is created (backend_admin_migrations_test.go keeps asserting it is absent) and no migration is added: preferences live in the existing backend_users.metadata jsonable column.'
+    - 'modules/boardwalk/dist is rebuilt and committed; scripts/check-admin-dist.sh, scripts/check-admin-openapi.sh --check, go vet ./..., go test -short ./..., the Docker-backed cabana preference tests, npm --prefix admin run test and typecheck, and go run ./cmd/summer docs:build --check all pass.

+<objective>
+Three admin minors for v0.2.1, all in the embedded admin SPA (`admin/`) and cabana:
+
+1. A manual theme switch (system / light / dark) on the rail's top icon, persisted per backend admin on the server and applied on load without a wrong-theme flash.
+2. An admin language switcher (in the user menu) that persists in the same per-admin storage and makes the SPA bundle and the server-side admin locale agree.
+3. The Settings rail item stays reachable on pages with the fixed bottom save bar.
+
+Then rebuild and commit the embedded dist and run every release gate. Release target v0.2.1, but nothing is tagged, pushed or deployed: that waits for the user.
+
+Purpose: the deployed v0.2.0 admin has a theme-looking icon that does nothing, no way to change the backend language, and Settings is covered on every form page.
+Output: local commits on `master` (code+docs commits per logical change, a test commit or two, one dist rebuild commit) and the quick SUMMARY.
+
+Hard limits: no tag, no push, no deploy. Other Claude sessions work in this repository: stage by explicit path, never `git add -A`; do not touch `.planning/STATE.md`, `.planning/state.json`, `.msd/` or `.planning/phases/17-blog-companions/17-VERIFICATION.md`. No co-author tags. One logical change per commit. Framework code, docs and tests never name a consuming application (use neutral names like `acme`).

+## Planning-time observations (2026-10-16, live, HEAD 1a03399)
+
+Edit scope rests on these facts. Re-check the ones a task's precondition names before editing.
+
+- Working tree: only `.planning/state.json` (modified), `.msd/` and `.planning/phases/17-blog-companions/17-VERIFICATION.md` (untracked), all other sessions' files. Nothing uncommitted under `modules/`, `admin/` or `docs/`.
+- **Per-admin storage already exists:** `backend_users.metadata` is WinterCMS's nullable jsonable TEXT column (`lagoon/backend_admin_migrations.go` migration `202610090001_backend_users_metadata`), mapped as `cabana.BackendUser.Metadata *string`. `modules/cabana/account.go` has `decodeMetadata`, `metadataString` and `setMetadataString` (keeps every other key, NULL/blank/`null`/`[]` = empty object, refuses non-object text with `errMetadataNotObject`), used today for the `subtitle` key. `lockAccount(ctx, tx, id)` (account.go:227) loads the admin's own row `FOR UPDATE`; `accountPrincipal(w, r)` (account.go:216) returns the backend principal or writes 401; `refusedAccountKeys` (account.go:445) is the unknown-key 422 pattern; `writeAccountError` maps `errAccountGone` to 401; `s.decodeCappedObject(w, r)` (relation_child.go:709) decodes a capped JSON object; `fieldMessage(ctx, tr, rule, field, params)` (field_file.go:885) renders `lagoon::validation.<rule>`.
+- **WinterCMS's preference table is deliberately not ported:** `modules/lagoon/backend_admin_migrations_test.go:116` fails if `backend_user_preferences` exists (Phase 9 decision, re-confirmed in 16.1 research). So: no new table, no migration; store under metadata keys `admin_theme` and `admin_locale`.
+- **Locale today:** surf's `Router.locale` (surf/router.go:861) wraps every request before any guard: a published `surf.LocaleResolver` (the translate plugin publishes one in deployed apps; its `Resolve` prefers URL prefix, then principal, then a remembered cookie, then Accept-Language) or else raw Accept-Language goes into `towel.WithLocale`. `cabana.schemaLocale` reads `towel.Locale`. `bouncer.Principal.PreferredLocale` exists ("empty means no override"), and surf registers the named middleware `locale.from-principal` (`surf.LocaleFromPrincipal`, router.go:534) that overrides the towel locale with it. cabana's `principalFrom` (auth.go:103) never sets it today. Because the resolver runs before the guard and a remembered cookie beats Accept-Language, sending a header from the SPA alone cannot fix the admin language: cabana must apply the preference after its guard.
+- cabana's guarded admin group is `r.GroupRaw(api, []string{"backend"}, ...)` (http.go:264). Account routes sit at http.go:266-275 wrapped in `interactiveOnly(...)` and, for writes, `requireAjax(...)`. The personal-token guard builds its principal with `g.users.FindByID` (token_guard.go:101), i.e. through `principalFrom`, then sets `principal.Scope = limit` (token_guard.go:119).
+- `GET /lang` (`cabana.langBundle`, lang.go) is public (outside the guard), resolves `schemaLocale` then `tr.Resolved(locale, "backend::lang.")`, answers `meta.locale`. Swag: `AdminLang` documents `Envelope[LangBundle]` (admin_openapi.go:167-175); `SuccessMeta` is shared by every envelope (admin_openapi.go:33), so new /lang meta needs its own type.
+- `phrasebook.Translator` has `Bundle`, `Resolved`, `Forms`, `Has` but no way to list the locales a prefix exists in. Framework admin strings: `modules/phrasebook/backend/lang/{en,pl}/lang.yaml` (groups `nav:` and `myaccount:` exist).
+- Route tables that enumerate cabana's mounted routes and must list new ones in the same commit (else `go test -short` fails): `security_coverage_test.go` `phase09Routes` (~L33-48), `token_routes_test.go` `tokenRouteClasses` (~L37-43) and `interactivePaths` (~L169-171), `phase10_coverage_test.go` unsafe-route `want` list (~L85-120; its method switch accepts only GET/POST/PUT/DELETE, so use PUT, not PATCH), `openapi_conformance_test.go` cases (account cases ~L716; `GET /lang` expects schema `cabana.Envelope-cabana_LangBundle` at ~L406).
+- Docker works for the current user (`docker info` = 29.7.2). Docker-backed cabana tests use `adminGorm(t)`, `adminHandler(t, gdb, nil)`, `insertAdmin`, `signIn`, `getAuth`, `adminAPI`, `profileOf` (see `TestAccountProfileSmoke`, account_test.go:266). `summer` is not on PATH: use `go run ./cmd/summer docs:build --check`.
+- **SPA theme today:** `admin/src/app/theme.ts` `applyColorScheme(win)` toggles `.dark` on `<html>` from `(prefers-color-scheme: dark)` and follows changes; `main.ts` calls it first in `boot()`. `main.css` uses `@custom-variant dark (&:where(.dark, .dark *))` and `.dark { color-scheme: dark; }`, so a class switch is the whole mechanism. The "theme-looking icon" is the decorative `<span ... title="SummerCMS">` with a lucide `Sun` at the top of the `<nav>` in `PluginRail.vue` (template, first child). lucide `Sun`, `Moon`, `SunMoon`, `Check` and Reka `DropdownMenuRadioGroup`/`DropdownMenuRadioItem`/`DropdownMenuItemIndicator`/`DropdownMenuLabel` are available in the installed versions.
+- **SPA locale today:** `i18n.ts` `loadStrings()` calls public `GET /lang` and `setBundle(data.data, data.meta.locale)` (sets `<html lang>`). Boot order in `main.ts`: strings, then `me()`, then navigation/settings/field types, then mount. `LoginView.submit` runs `login`, `me()`, then the same loads. `useAuth.me()` (useAuth.ts:56) sets the profile and the list-state owner.
+- **CSP:** boardwalk sends `script-src 'self'`, so no inline script in `index.html`. Applying the cached theme synchronously at the top of `boot()` (before any await; the app mounts only after `me()`) is the no-flash approach.
+- **Settings bug:** `PluginRail` is `sticky top-0 h-screen self-start` with Settings pinned at its bottom; the four bottom bars are `fixed inset-x-0 bottom-0 z-30` and span the whole viewport, covering the rail bottom: `FormView.vue:596`, `SettingsFormView.vue:222`, `AccountView.vue:425`, `PreviewView.vue:285`. Sidebar widths are tokens `--spacing-rail: 96px` and `--spacing-panel: 224px` (main.css:72-73); the section panel shows when `active && !collapsed` in `AppShell.vue`.
+- `FormView.vue` registers `beforeunload` for unsaved changes (L530), so a page reload after a language switch is guarded by the browser prompt.

+Backend (one commit, e.g. `feat(cabana): per-admin theme and locale preferences`):
+
+- phrasebook: add `func (t *Translator) Locales(prefix string) []string` returning the sorted locale codes whose catalog holds at least one key starting with prefix (nil-safe like `Resolved`; nil translator or catalog returns nil). This is the single definition of "supported admin locale": `tr.Locales("backend::lang.")` (en and pl in the framework, plus any locale an application overrides). Document it in `modules/phrasebook/README.md` (Features bullet next to Bundle/Resolved and an API reference row) and in `docs/services/localization.md` (the admin SPA paragraph).
+- New file `modules/cabana/account_preferences.go`: constants for the metadata keys `admin_theme` and `admin_locale`; the theme set system, light, dark (system is the default); `preferencesOf(user BackendUser, tr *phrasebook.Translator) AdminPreferences` (theme = stored value when it is one of the three, else system; locale = stored value only when it is in `tr.Locales(adminLangPrefix)`, else ""). Handlers on `*service`:
+  - `accountPreferencesGet` (GET /account/preferences): `accountPrincipal`, load the row like `me` does (missing or deactivated = 401), answer `WriteData(..., preferencesOf(user, tr), ...)`.
+  - `accountPreferencesUpdate` (PUT /account/preferences): `accountPrincipal`; `s.decodeCappedObject` (errors via `writeRelationError` as accountUpdate does); every key other than theme and locale is a 422 on that key with the existing `myaccount.field_not_editable` message and nothing is written (mirror `refusedAccountKeys` with a preference key list). Each present key is saved, an absent key keeps its stored value, `{}` answers 200 with the current preferences and writes nothing (document this partial semantics in the swag description). theme must be a JSON string in the set; locale must be a JSON string that is "" or in `tr.Locales(adminLangPrefix)`; a wrong value or type is a 422 on that field with `fieldMessage(ctx, tr, "in", field, nil)`. Inside `lagoon.Transaction`: `lockAccount(ctx, tx, principal.ID)`, apply each key with `setMetadataString` (theme system and locale "" remove the key, so an untouched admin keeps NULL metadata); `errMetadataNotObject` is a 422 on the submitted field(s) with a new `myaccount.preferences_unavailable` message; write only the metadata column with `UpdateColumns` (a UI preference is not a profile edit, so updated_at stays). Errors go through `writeAccountError`. Answer the saved `AdminPreferences`. The row is always the principal's; never read an id from the path or body.
+- `admin_openapi.go`: `AdminPreferences {Theme string json:"theme"; Locale string json:"locale"}` with comments naming the allowed values; `AdminPreferencesRequest {Theme *string json:"theme,omitempty"; Locale *string json:"locale,omitempty"}`; add `Preferences AdminPreferences json:"preferences"` to `AdminProfile` (additive; `profileFor` in account.go fills it with `preferencesOf(user, s.translator())`, so GET /auth/me and the My account answers carry it). Swag functions `AdminAccountPreferences` (GET, `Envelope[AdminPreferences]`, 401/403) and `AdminAccountPreferencesUpdate` (PUT, body `AdminPreferencesRequest`, 200/401/403/413/422), both stating "Interactive session only (403 interactive_only for personal API tokens)". Update the `AdminMe` description to mention preferences.
+- `http.go` service.mount, next to the other account routes: `g.Get("/account/preferences", interactiveOnly(s.accountPreferencesGet))` and `g.Put("/account/preferences", interactiveOnly(requireAjax(s.accountPreferencesUpdate)))`.
+- Add both routes to the route tables in the same commit: `phase09Routes` (security_coverage_test.go), `tokenRouteClasses` as classInteractive and `interactivePaths` (token_routes_test.go), the unsafe `want` list for PUT (phase10_coverage_test.go), and conformance cases for both (openapi_conformance_test.go, modelled on the PUT /account case).
+- Lang strings in both `backend/lang/{en,pl}/lang.yaml`: `nav.theme` with a `:mode` placeholder (en "Theme: :mode", pl "Motyw: :mode"), `nav.theme_system`/`nav.theme_light`/`nav.theme_dark` (System/Light/Dark; Systemowy/Jasny/Ciemny), `nav.language` (Language/Język), `myaccount.preferences_unavailable` (the subtitle_unavailable wording for preferences), `myaccount.preferences_failed` (en "Your preference could not be saved.", pl "Nie udało się zapisać ustawienia.").
+- Run `scripts/check-admin-openapi.sh` to regenerate `admin/openapi/admin.json` and `admin/src/api/schema.d.ts`; add `export type AdminPreferences = Schemas['cabana.AdminPreferences']` to `admin/src/api/types.ts`; give the typed profile fixtures in `admin/tests/helpers.ts` (and any other test fixture typed as AdminProfile that typecheck flags) `preferences: { theme: 'system', locale: '' }`, so this commit keeps `npm --prefix admin run typecheck` green.
+- Docs in the same commit (CLAUDE.md docs rule): `modules/cabana/README.md` (My account Features bullet: preferences under metadata keys admin_theme/admin_locale, other keys kept; route table rows for GET and PUT /account/preferences; API reference rows for `cabana.AdminPreferences`, `cabana.AdminPreferencesRequest`, `cabana.AdminAccountPreferences`, `cabana.AdminAccountPreferencesUpdate`; the `cabana.AdminProfile` row mentions `preferences`), `docs/backend/users-and-permissions.md` (My account section: the preferences wire contract and validation), `docs/backend/admin-spa.md` (the rail's theme switch).
+- Smoke test `modules/cabana/account_preferences_test.go` (package cabana_test, Docker-backed, skips under -short like its neighbours): `TestAccountPreferencesSmoke` signs in a fresh admin, PUTs `{"theme":"dark"}`, expects 200 with theme dark and locale "", then GET /auth/me shows `preferences.theme` dark and GET /account/preferences agrees; a subtitle stored beforehand is still in metadata.
+
+SPA (second commit, e.g. `feat(admin): manual theme switch on the rail`):
+
+- `theme.ts`: export `ThemeChoice` ('system' | 'light' | 'dark'), the ordered `THEME_CHOICES` and an `isThemeChoice` guard; extend `applyColorScheme(win = window, choice: ThemeChoice = 'system')`: light removes `.dark`, dark adds it (both return a no-op unsubscribe and subscribe to nothing), system keeps today's media-query behaviour. The default argument keeps the existing call and test valid. Update the header comment (A6 is superseded: system is the default, light and dark are manual).
+- New `admin/src/state/usePreferences.ts`: `THEME_KEY = 'summer-admin.theme'`; module state for the current choice exposed readonly as `themeChoice`; `applyTheme(choice)` (stops the previous media subscription, applies the new one); `cachedTheme()` reads localStorage and returns only a valid choice, else 'system' (guard storage access with try/catch exactly like useSidebar.ts); `setTheme(choice)` applies and caches optimistically, sends `api.PUT('/account/preferences', { body: { theme: choice } })` and on any failure reverts theme and cache and calls `showToast(t('backend::lang.myaccount.preferences_failed'), 'danger')`; `nextTheme` (system -> light -> dark -> system) and `cycleTheme()`; `applyProfilePreferences(profile)` applies and caches `profile.preferences.theme` when valid (tolerate a missing preferences object at runtime). Locale handling is added in Task 2.
+- `useAuth.me()`: after the profile loads, await `applyProfilePreferences(user.value)` (covers boot and LoginView). `main.ts`: replace the first `applyColorScheme()` call with `applyTheme(cachedTheme())`, still before any await. `useSidebar.ts`: update the storage comment (usePreferences also writes browser storage: the theme and locale codes, never tokens or record data).
+- `PluginRail.vue`: replace the decorative top span with `<button type="button" data-theme-toggle>` keeping its size, radius, `bg-accent-soft` and `text-accent` icon (size 22), adding a hover state; the icon is `SunMoon` for system, `Sun` for light, `Moon` for dark; `aria-label` and `title` are `t('backend::lang.nav.theme', { mode: t('backend::lang.nav.theme_' + choice) })`; click calls `cycleTheme`.

+Backend (commit, e.g. `feat(cabana): admin language follows the stored preference`):
+
+- `auth.go` `principalFrom`: set `PreferredLocale` to `metadataString(user.Metadata, <admin_locale key>)` (empty when unset, so nothing changes for admins without a preference). The value was validated on write, and `schemaLocale` plus `tr.Resolved` already fall back for an unknown code.
+- `token_guard.go`: right where `principal.Scope = limit` is set, also clear `principal.PreferredLocale`, with a comment: personal API tokens keep the request locale; the stored admin language applies to interactive sessions only (API-token clients see no behaviour change).
+- `http.go`: the guarded group becomes `r.GroupRaw(api, []string{"backend", "locale.from-principal"}, ...)`, so surf's `LocaleFromPrincipal` runs after the backend guard and overrides the towel locale (whatever the LocaleResolver or Accept-Language chose) for interactive admins who have a preference. If a cabana test harness router rejects the name, register it there the way surf does; do not add a cabana copy of the middleware.
+- `lang.go` `langBundle`: compute `locales := tr.Locales(adminLangPrefix)` (empty slice when tr is nil); when the query parameter `locale` is non-empty and in `locales`, use it in place of `schemaLocale(...)`; any other value is ignored (never echoed, never an error). Answer meta `{"locale": resolved, "locales": locales}`. Keep `Cache-Control: no-cache`.
+- `admin_openapi.go`: `LangMeta {Locale string json:"locale"; Locales []string json:"locales"}` and `LangEnvelope {Data LangBundle json:"data"; Meta LangMeta json:"meta"}`; `AdminLang` gets `@Param locale query string false "..."` and `@Success 200 {object} LangEnvelope`, and its description explains the parameter and `meta.locales`. Update the GET /lang conformance case to the new schema name (plus a `?locale=pl` request). Regenerate with `scripts/check-admin-openapi.sh`.
+- Extend `account_preferences_test.go` (Docker-backed): `TestAdminLocalePreference`: after PUT `{"locale":"pl"}` a guarded admin route answers in Polish with `Accept-Language: en` (use a response that reflects the request locale, e.g. the 422 message of PUT /account/preferences with an invalid theme, or `meta.locale` of a schema route the harness mounts); PUT `{"locale":"xx"}` is a 422; `GET /lang?locale=pl` has meta.locale pl and meta.locales containing en and pl; `GET /lang?locale=xx` falls back to the request locale.
+- Docs in the same commit: `modules/cabana/README.md` (GET /lang row: `locale` parameter and `meta.locales`; the admin language override for interactive sessions; API reference rows `cabana.LangMeta` and `cabana.LangEnvelope`), `docs/services/localization.md` (admin language: preference, then request locale), `docs/backend/admin-spa.md` (strings from `GET /lang?locale=`, the language switcher).
+
+SPA language (commit, e.g. `feat(admin): language switcher in the user menu`):
+
+- `i18n.ts`: `loadStrings(preferred?: string)` sends `params: { query: { locale } }` only when preferred is non-empty; store `meta.locales` in a module ref exported readonly as `availableLocales` (default empty).
+- `usePreferences.ts`: `LOCALE_KEY = 'summer-admin.locale'`; `cachedLocale()` returns the stored value only when it is a short locale-shaped code (letters with an optional region, at most 16 characters), else ""; `applyProfilePreferences` also handles locale: a non-empty `profile.preferences.locale` that differs from `currentLocale` triggers `await loadStrings(locale)`, then the cache is set (or removed when the preference is ""); `setLocale(code)` does nothing for the current preference, otherwise PUTs `{ locale: code }`, and on success caches it and reloads the page through a small exported indirection (for example `page.reload()` wrapping `window.location.reload()`) that tests can stub; on failure it shows the preferences_failed toast. A reload re-fetches strings, navigation, settings, schemas and field types in the new language at once; unsaved forms are protected by FormView's beforeunload prompt.
+- `main.ts`: `await loadStrings(cachedLocale() || undefined)`.
+- `UserMenu.vue`: between the account item and the logout separator, when `availableLocales.length > 1`: a `DropdownMenuSeparator`, a `DropdownMenuLabel` with `t('backend::lang.nav.language')`, and a `DropdownMenuRadioGroup` whose model is the profile's preference locale or else `currentLocale`, with one `DropdownMenuRadioItem` per code (`data-locale-option` set to the code, a `Check` icon in `DropdownMenuItemIndicator`), labelled with the language's own name via `Intl.DisplayNames([code], { type: 'language' })` with the first letter upper-cased and the upper-cased code as fallback; selection calls `setLocale`. Match the existing item classes.
+
+Footer layout (separate commit, e.g. `fix(admin): bottom save bars no longer cover the sidebar`):
+
+- `AppShell.vue`: bind a `--shell-offset` CSS custom property on the root element: `calc(var(--spacing-rail) + var(--spacing-panel))` when the section panel is shown (`active && !collapsed`), else `var(--spacing-rail)`.
+- In the four bottom bars (`FormView.vue`, `SettingsFormView.vue`, `AccountView.vue`, `PreviewView.vue`) replace `inset-x-0` with `right-0 left-[var(--shell-offset,0px)]`, keeping everything else. The bar then starts at the sidebar's right edge, the sticky rail and its Settings item stay uncovered, and the bar follows the panel collapsing or expanding. Leave the Toast, dialogs and the flyout alone.

+Unit tests come last (CLAUDE.md project rule 2). Go tests (commit, e.g. `test(cabana): admin preference coverage`):
+
+- `translator_test.go`: `Locales` returns sorted codes that hold keys under the prefix, leaves out locales without such keys, and returns nil for a nil translator.
+- `account_preferences_internal_test.go` (package cabana, Docker-free): `preferencesOf` (unset gives system and ""; an invalid stored theme gives system; an unsupported stored locale gives ""; NULL, `[]` and malformed metadata are tolerated); setting theme and locale keeps subtitle and an unrelated Winter key; system and "" remove their keys and empty metadata becomes NULL; non-object metadata is refused; `principalFrom` sets PreferredLocale from admin_locale and leaves it empty without one.
+- Extend `account_preferences_test.go` (Docker-backed): unknown keys (`id`, `backend_user_id`, `is_superuser`) are a 422 per key and the row is unchanged; theme `"blue"` and theme `1` are 422; the save is visible only to its owner (a second admin's GET still shows defaults); a personal API token gets 403 `interactive_only` on GET and PUT; a cookie PUT without X-Requested-With gets 403; non-object metadata is a 422 and stays byte-identical; an API-token request to a guarded route keeps its Accept-Language locale even though the owner chose pl.
+
+Vitest (commit, e.g. `test(admin): theme switch, language switcher and footer offset`): add the new lang keys to `tests/fixtures/lang.json` (and `meta.locales` ["en","pl"] where the fixture models the /lang answer); make `resetState()` in `tests/helpers.ts` also reset the theme to system.
+
+- `theme.test.ts`: light and dark ignore the media query and subscribe to nothing; system follows it (keep the existing cases).
+- `i18n.test.ts`: `loadStrings('en')` sends `?locale=en`, a call without an argument sends no locale, and `availableLocales` follows meta.locales.
+- New `state/usePreferences.test.ts`: `cachedTheme`/`cachedLocale` reject invalid stored values; `cycleTheme` order and the PUT body; a failed PUT reverts the theme and the cache and shows a danger toast; `applyProfilePreferences` applies the theme and reloads strings only when the locale differs; `setLocale` PUTs, caches and calls the stubbed reload, and on failure does not reload.
+- `PluginRail.test.ts`: the `data-theme-toggle` button's aria-label names the current choice and a click cycles it and PUTs; the Settings link is still rendered.
+- `UserMenu.test.ts`: with locales en and pl the menu lists `data-locale-option` items named English and polski/Polski, the current one checked; selecting the other one PUTs; with a single locale the group is absent.
+- `AppShell.test.ts`: `--shell-offset` equals the rail width with the panel collapsed and rail plus panel with it shown. `FormView.test.ts`: the footer class contains `left-[var(--shell-offset`.
+
+Release build (commit, e.g. `build(admin): rebuild embedded admin dist for v0.2.1`): `npm --prefix admin run build`, then stage `modules/boardwalk/dist` by path (include deletions of replaced hashed assets: `git add -- modules/boardwalk/dist` stages that directory only, which is allowed; never `git add -A`).
+
+Then run the full gate list in `<verify>` and record every result in the SUMMARY. A failure means fixing the cause in the owning task's files and committing the fix as its own commit. Do not tag, push or deploy: the SUMMARY ends with the release steps that wait for the user's go-ahead (tag v0.2.1, push, deploy per application).

+## Trust Boundaries
+
+| Boundary | Description |
+|----------|-------------|
+| browser (SPA) -> cabana admin API | Untrusted JSON on PUT /account/preferences and an untrusted `locale` query on public GET /lang cross here. |
+| backend_users.metadata -> request locale | A stored, admin-written value becomes `bouncer.Principal.PreferredLocale` and then the towel locale of admin requests. |
+| localStorage -> SPA boot | Cached theme and locale codes, writable by any script or user on the origin, are read before authentication. |
+| personal API token clients -> admin API | Machine clients (MCP server and others) must see no behaviour change from an admin's UI preference. |
+
+## STRIDE Threat Register
+
+| Threat ID | Category | Component | Severity | Disposition | Mitigation Plan |
+|-----------|----------|-----------|----------|-------------|-----------------|
+| T-261016-0fm-01 | Elevation of privilege | PUT /account/preferences (`accountPreferencesUpdate`) | high | mitigate | The row is always `accountPrincipal(...).ID` locked with `lockAccount`; no id is read from the path or body; any key other than theme/locale (id, backend_user_id, is_superuser, ...) is a 422 and nothing is written. Docker test proves another admin's row is untouched and unknown keys are refused. |
+| T-261016-0fm-02 | Spoofing (CSRF) | PUT /account/preferences with the admin cookie | high | mitigate | `requireAjax` wraps the PUT (X-Requested-With required on cookie requests); listed in the phase10 unsafe-route walk; Docker test sends a cookie PUT without the header and expects 403. |
+| T-261016-0fm-03 | Elevation of privilege | GET/PUT /account/preferences with a personal API token | medium | mitigate | Both routes wrapped in `interactiveOnly` (403 `interactive_only`), classified `classInteractive` in token_routes_test.go; Docker test with a `*`-scope token. |
+| T-261016-0fm-04 | Tampering | preference values | medium | mitigate | theme must be one of system/light/dark; locale must be "" or in `phrasebook.Translator.Locales("backend::lang.")`; wrong types are 422; the body is size-capped by `decodeCappedObject`. Internal and Docker tests cover each refusal. |
+| T-261016-0fm-05 | Tampering | backend_users.metadata (shared with subtitle and copied WinterCMS keys) | medium | mitigate | `setMetadataString` keeps every other key and refuses non-object metadata (422, never overwritten); read-modify-write happens under the `FOR UPDATE` row lock inside `lagoon.Transaction`, so it cannot race PUT /account's subtitle save. Tests assert subtitle and an unrelated key survive and non-object metadata stays byte-identical. |
+| T-261016-0fm-06 | Tampering / Information disclosure | GET /lang `?locale=` (public) | low | mitigate | The parameter is used only when it equals a code in `Translator.Locales`; anything else is ignored, never echoed and never errors; the response keeps `Cache-Control: no-cache`; only the public backend::lang namespace is ever served. |
+| T-261016-0fm-07 | Information disclosure (behaviour change) | personal-token principal locale | medium | mitigate | token_guard clears `PreferredLocale` on token principals, so `locale.from-principal` is a no-op for them; Docker test proves an API-token request keeps its Accept-Language locale after the owner chose pl. |
+| T-261016-0fm-08 | Tampering | localStorage summer-admin.theme / summer-admin.locale | low | accept | Values are validated (theme enum, locale-shaped code of at most 16 characters) before use; an invalid locale is also ignored by the server; the server preference overwrites the cache after `me()`; the effect is limited to the local user's own display. |
+| T-261016-0fm-09 | Information disclosure | cached theme/locale surviving logout on a shared device | low | accept | The values are display settings, not personal data or credentials (T-16.1-03 covers list queries, which are still cleared); keeping them lets the login screen show the last language. |
+| T-261016-0fm-10 | Denial of service | stored locale feeding the translator | low | mitigate | Written values are restricted to supported locales; `schemaLocale`/`Translator.Resolved` fall back to the default for any unknown code, so a stale stored value (locale removed later) degrades to the default language, never an error. |
+| T-261016-0fm-SC | Tampering | npm/Go dependency installs | low | accept | No new dependency: everything uses installed packages (lucide icons, Reka DropdownMenu radio parts, stdlib); `npm --prefix admin ci` uses the committed lockfile. No package-legitimacy checkpoint is needed. |

+- Task 3's verify line is the release gate list: `go vet ./...`, `go test -short ./...`, the Docker-backed cabana preference, route-table and conformance tests (`TestPhase09*`, `TestPhase10*` including `TestPhase10OpenAPIConformance`, `TestTokenRouteGates`, `TestInteractiveOnly`), lagoon `TestBackendAdminMigration` (backend_user_preferences still absent) and `TestBackendAdminMetadataColumn`, docs checker (`TestDocsTree` and `go run ./cmd/summer docs:build --check`), `examples/hello`, admin typecheck and vitest, `scripts/check-admin-openapi.sh --check`, `scripts/check-admin-dist.sh`, and a clean `modules/ admin/ docs/` tree.
+- Hand check (record in SUMMARY): `git log --format='%H %s%n%b' 1a03399..HEAD` shows no co-author tag and no `.planning/state.json`, `.msd/` or 17-VERIFICATION.md in any commit (`git diff --name-only 1a03399..HEAD`); `git diff 1a03399..HEAD -- modules docs admin/src admin/tests | grep -ci grzyby` prints 0 (no consuming application named); `git tag --points-at HEAD` prints nothing.
+- Optional manual check if a dev server is at hand: `npm --prefix admin run dev` against a running `summer serve`, open a record form, confirm Settings is clickable above the save bar, toggle the theme and the language.

+
+<success_criteria>
+- The rail's top icon switches the theme system/light/dark, persisted per admin on the server and applied on load from the cache without a wrong-theme render.
+- The user menu switches the admin language between the available admin locales; after the reload the SPA strings and the server-side admin locale agree, independent of Accept-Language and the translate plugin's cookie; API-token clients are unaffected.
+- Settings stays reachable on every page with the bottom save bar.
+- GET/PUT /account/preferences are own-row only, validated, CSRF- and token-guarded, documented, and in the OpenAPI document and TS types.
+- Embedded dist rebuilt and committed; all gates green; no tag, push or deploy.

+# Phase quick-261016-0fm Plan 01: Admin minors for v0.2.1 Summary
+
+Admins get a server-stored theme switch (system, light, dark) on the rail's top button and a language switcher in the user menu. The stored admin language overrides the request locale on guarded admin routes for interactive sessions only. The fixed save bars now start at the sidebar's right edge, so the rail's Settings item stays clickable. The embedded dist is rebuilt and every release gate passes. Nothing is tagged, pushed or deployed.

+
+## What was built
+
+- **Preferences API (cabana):** `GET` and `PUT /account/preferences`. Both are wrapped in `interactiveOnly`, and the PUT also in `requireAjax`. They act only on the principal's own row, locked with `lockAccount`. PUT accepts only `theme` and `locale`, saves each key that is present and keeps the stored value of an absent key. Validation: theme must be in {system, light, dark}; locale must be `""` or a code in `Translator.Locales("backend::lang.")`; a wrong type is a 422. Metadata that is not a JSON object is a 422 and is never overwritten. `AdminProfile.preferences` is filled by `profileFor`.
+- **Locale override:** `principalFrom` sets `PreferredLocale` from `admin_locale`, and `token_guard` clears it for personal tokens. The guarded group is now `[]string{"backend", "locale.from-principal"}`. `GET /lang` honours a `?locale=` only when it is a supported admin locale, and answers `meta.locales`.
+- **SPA:**
+  - `theme.ts` gained `ThemeChoice`, `THEME_CHOICES`, `isThemeChoice` and the choice argument to `applyColorScheme`.
+  - New `usePreferences.ts`: theme and locale state, the localStorage cache, the PUT, revert with a toast on failure, apply-on-load, and `setLocale` followed by a stubbable `page.reload()`.
+  - Boot applies the cached theme before the first await and loads strings in the cached language.
+  - Rail button with `data-theme-toggle`: SunMoon/Sun/Moon icon and a translated label.
+  - User menu: `DropdownMenuRadioGroup` of the admin locales, each named in its own language via `Intl.DisplayNames`.
+- **Layout:** `AppShell` binds `--shell-offset` (rail, or rail plus panel). The four save bars use `right-0 left-[var(--shell-offset,0px)]`; the compiled CSS rule is confirmed in the dist.
+- **Docs:** cabana README (feature bullet, route rows, override paragraph, API reference rows), phrasebook README, `users-and-permissions.md` (Preferences), `admin-spa.md` (theme switch, language switcher, `?locale=`) and `localization.md` (`Locales`, precedence).

+## Gate results (final run at 66fd4ae)
+
+| Gate | Result |

+| `go vet ./...` | PASS |
+| `go test -short ./...` | PASS |
+| Docker cabana: `TestAccountPreferences*`, `TestAdminLocalePreference`, `TestAuthMe*`, `TestAccountProfile*`, `TestPhase09*`, `TestPhase10*` (incl. OpenAPI conformance), `TestTokenRouteGates`, `TestInteractiveOnly` | PASS |
+| Docker lagoon: `TestBackendAdminMigration` (backend_user_preferences still absent), `TestBackendAdminMetadataColumn` | PASS (both ran, not skipped) |
+| Full Docker-backed `go test ./...` (extra) | PASS |
+| `go test ./cmd/summer -run TestDocsTree` | PASS |
+| `go run ./cmd/summer docs:build --check` | PASS ("no problems found") |
+| `examples/hello` `go test ./...` | PASS |
+| `npm --prefix admin run typecheck` | PASS |
+| `npm --prefix admin run test` | PASS (93 files, 1429 tests) |
+| `scripts/check-admin-openapi.sh --check` | PASS |
+| `scripts/check-admin-dist.sh` | PASS ("matches a fresh build") |
+| clean `modules/ admin/ docs/` tree | PASS |
+
+Docker was available to the current user (29.7.2); no `sudo -u golem` was needed.
+
+Hand checks: 0 co-author lines in `1a03399..HEAD`. No `.planning/state.json`, `.msd/` or `17-VERIFICATION.md` in any commit. `grzyby` appears 0 times in the modules/docs/admin diff. `git tag --points-at HEAD` is empty.
+
+A mutation check confirmed that `TestAccountPreferencesAuthorization` fails when the `PreferredLocale` clear in `token_guard.go` is removed: the token request then answers `pl`. The file was restored from HEAD afterwards.
+
+## Deviations from Plan
+
+### Auto-fixed Issues
+
+**1. [Rule 1 - Bug] The rail theme label used a template-string lang key**
+- **Found during:** Task 2, the first short-test run after commit 21b0d39.
+- **Issue:** `phrasebook`'s `TestPhase10SPAKeysResolve` scans `admin/src` for `backend::lang.*` literals and found the unresolvable prefix `backend::lang.nav.theme_`. Commit 21b0d39 on its own therefore fails `go test -short ./modules/phrasebook`. This is the one commit in the series that is not green on its own.
+- **Fix:** a `themeModes` map with full key literals.
+- **Files:** `admin/src/components/shell/PluginRail.vue`
+- **Commit:** 3d2f9d0
+
+**2. [Rule 3 - Blocking] Route-count and envelope tests outside the plan's list**
+- `phase10_csrf_test.go` counts state-changing routes. The count went from 33 to 34 for `PUT /account/preferences`, in commit 047858a.
+- `messages_test.go` decodes `/lang` with `DisallowUnknownFields`, so its meta struct gained `locales`. `admin/tests/fixtures/typed.ts` (now `cabana.LangEnvelope`) and the `meta.locales` field of `admin/tests/fixtures/lang.json` were updated in the same commit to keep typecheck green. Both changes are in f67e891.
+
+**3. [Rule 3 - Blocking] Theme cache vs the existing storage-invariant tests**
+- Existing tests assert that the sidebar key is the only localStorage entry after sign-in or logout. Caching `system` would have broken them, so the default choices are stored as absent keys, which is equivalent for `cachedTheme()` and `cachedLocale()`.
+
+### Executor-discretion choices
+- The `admin-spa.md` theme paragraph went into the SPA commit (21b0d39) rather than the backend commit, because it describes SPA behaviour.
+- `resetState()` resets the theme and locale preference through `applyProfilePreferences(profile.data)`, so no test-only hook was added to the source.
+- The earlier gofmt-induced reflow of `token_routes_test.go` (the file was already not gofmt-clean) was reverted to a minimal diff.
+
+### Notes
+- One run of `tests/shell` failed once in the timing-sensitive "keeps the flyout open while focus stays on its rail item" test, then passed on rerun and in every full run since. This looks like existing flakiness, not a regression.
+- The execution was interrupted by an auth error mid Task 1. All uncommitted edits were intact on resume, and nothing was lost or redone.
+
+## Known Stubs
+
+None.
+
+## Threat Flags
+
+None beyond the plan's threat model. Every `mitigate` entry is implemented and tested:
+- T-01: own row and refused keys.
+- T-02: cookie PUT without the header gets 403.
+- T-03: token gets 403 interactive_only.
+- T-04: value and type refusals.
+- T-05: other keys kept, non-object metadata stays byte-identical.
+- T-06: unsupported `?locale` ignored, never echoed.
+- T-07: tokens keep the request locale (mutation-checked).
+- T-10: stale values degrade to defaults in `preferencesOf`.
+
+## Release steps pending the user's go-ahead
+
+1. Tag `v0.2.1` on `master` at or after 66fd4ae, once the orchestrator's docs commit lands.
+2. Push `master` and the tag.
+3. Bump the framework in consuming applications and deploy each per its own DEPLOY.md.
+
+## Self-Check: PASSED
+
+- Files: `modules/cabana/account_preferences.go`, `modules/cabana/account_preferences_test.go`, `modules/cabana/account_preferences_internal_test.go`, `admin/src/state/usePreferences.ts` and `admin/tests/state/usePreferences.test.ts` all exist.
+- Commits: 047858a, 21b0d39, 3d2f9d0, f67e891, 5244a37, 85e52d9, 119f1f8, f0ab26b and 66fd4ae are all present in `git log`.

+
+No push, tag or release. Plugin repos commit first; disposition and summary here afterwards.
+
+## Tasks
+
+1. **WR-01** `Service.Cancel` takes `SubscriptionLockKey` around the gateway call and the local flag write.
+2. **WR-02** `ApplyDeleted` fires `SubscriptionCanceled` only on a transition into canceled; ordering tests count canceled == 1.
+3. **WR-03** `SyncPlan` (detached path) runs under a per-plan session lock on a fresh copy of the row; `V1Products.Create` carries an idempotency key.
+4. **WR-04** Guarded checkout expires the customer's open subscription-mode Checkout Sessions inside the subscriber lock (optional gateway interface, implemented by pgstripe).
+5. **WR-05** Plan sync prices every currency the plan lists that the gateway supports, not the fixed usd/eur/pln list.
+6. **WR-06** The gateway retrieves the price before the session and refuses (`ErrNoPriceForCurrency`) when amount, currency or active differ from the plan.
+7. **WR-07** `incomplete` no longer blocks a checkout; the guarded checkout cancels the subscriber's incomplete subscriptions at the gateway inside the lock.
+
+## Verify
+
+`go vet ./...` and `go test ./...` (Docker) green in both plugin repos.
+
+## Added during execution
+
+8. **G-18.1-8** pgsub cannot boot in a `summer build` app: `bootService` required `*gorm.DB` at Boot, but the generated main.go activates plugins before any command opens the database. Build the service through `lagoon.OnDatabase`; add a test whose host activates plugins before publishing the database.

+Other boot-time lookups checked: pgsub's API, admin controllers and pgstripe (root and subscriptions) all look up `*gorm.DB` and `*classes.Service` lazily at request or job time.
+
+## Verification
+
+- `go vet ./...` and `go test ./...` (Docker) green in sm-paymentgatewaysubscriptions-plugin and sm-pgstripe-plugin.
+- New tests: pgsub `TestCheckoutIncompleteAndOpenSessions`, `TestCancelTakesSubscriptionLock`, `TestSyncPlanSerialised`, `TestCheckoutPriceUnavailable`, `TestBootBeforeDatabase`; pgstripe `TestReviewFixesGateway`.
+- api-coverage gate passes after the COVERAGE.md update (checkout.sessions list/expire, prices.retrieve, products.create key).
+
+## Notes
+
+- pgstripe now uses pgsub API added here (`contracts.CheckoutSessionExpirer`, `contracts.ErrPriceUnavailable`); it builds through the go.work replace. A release must tag pgsub first and bump pgstripe's `require`.
+- `.planning/STATE.md` was not updated: it carries another session's uncommitted edits.

+# Quick 261016-nqk: close UAT gaps G-18.1-7 and G-18.1-4
+
+No push, tag or release. Framework first (pgsub needs its new hooks), then the plugins; planning docs last.
+
+## Tasks
+
+1. **G-18.1-7 (pgstripe).** The decoded subscription maps `cancel_at_period_end` true for Stripe's flag or a `cancel_at` date while active or trialing; a cleared `cancel_at` maps back. One choke point (`subscriptionObject.args`) serves the snapshot, the fresh retrieval and `SyncSubscription`. Tests: both payload shapes, un-cancel, `cancel_at` in past_due/canceled; Postgres smoke of portal cancel then un-cancel (reactivated once). README, COVERAGE row, D-21 amendment.
+2. **G-18.1-4 (preview labels, pgsub).** The label element renders its `value` property (the SPA's plugin-element contract), not only the attribute. Node-run test.
+3. **G-18.1-4 (framework).** `pact.ListExtendRecords` (once per list page, before columns are read; unstored `gorm:"-"` columns compile unsortable and refuse sortable/searchable) and `pact.FormRecordTitle` (`meta.title` on show/create/update; the SPA heads form and preview with it). Roster fixture tests, SPA tests, docs, OpenAPI, admin dist.
+4. **G-18.1-4 (pgsub).** Subscriber column (e-mail, else name; `<alias> #<id>` fallback) through `ListExtendRecords` and the optional `contracts.SubscriberBatchResolver` (user resolver implements `ResolveMany`); subscriber type and id become invisible searchable columns; preview title "Subscription #<id> (<plan>)" (en/pl). Tests, README.
+5. Rebuild the UAT demo app and check the admin API.

+
+Nothing pushed, tagged or released.
+
+| Gap | Fix | Commit |
+|-----|-----|--------|
+| G-18.1-7 | `cancel_at_period_end` = Stripe's flag, or a `cancel_at` date on an active or trialing subscription; un-cancel maps back and fires reactivated. D-21 amended; COVERAGE row now INTEGRATE | pgstripe a5b3314 |
+| G-18.1-4 (empty Gateway/Status on preview) | the label element renders its `value` property (the SPA sets the property, the element read only the attribute) | pgsub 6a3f2c4 |
+| G-18.1-4 (framework) | `pact.ListExtendRecords`, `pact.FormRecordTitle` (`meta.title`), unstored list columns unsortable/unsearchable; SPA uses `meta.title`; docs, OpenAPI, dist | summercms.go bc5685e, 013890c, 17398fe |
+| G-18.1-4 (subscriber, title) | list column `subscriber` (e-mail, else name, `<alias> #<id>` fallback) via the new optional `contracts.SubscriberBatchResolver`; type/id invisible but searchable; preview title "Subscription #<id> (<plan>)" / "Subskrypcja #<id> (<plan>)" | pgsub d5579cd |
+
+The screenshot's "Cancel at Period End: No / Canceled At: —" was stale: the preview API for subscription 1 returns `cancel_at_period_end: true` and `canceled_at` (checked on the demo, before and after the rebuild).
+
+## Verification
+
+- summercms.go: `go vet ./...`, `go test ./...` (Docker), `summer docs:build --check`, `TestDocsTree`, admin vitest 1431/1431 and typecheck, `check-admin-openapi.sh`, `check-admin-dist.sh`.
+- pgsub and pgstripe: `go vet ./...`, `go test ./...` (Docker) green; the new subtests ran (not skipped).
+- Demo app rebuilt without overlays and restarted: list row `subscriber: customer@example.test`, preview `meta.title: "Subscription #1 (Pro)"`, `gateway: Stripe`, `stripe_status: Active`; the new admin bundle is served.
+
+## Release notes
+
+- pgsub now needs the framework's `pact.ListExtendRecords` and `pact.FormRecordTitle`: tag the framework (v0.2.2) first, bump pgsub's `require`, tag pgsub, then pgstripe (already needs unreleased pgsub from 261016-myi).
+- Search by subscriber e-mail is not offered: cabana searches stored columns and relations only, and the subscriber is polymorphic. Type and id stay searchable.
+- UAT 7 and the site-side cancel still need a live re-run in the demo.

+<objective>
+Two admin fixes for the payment gateway plugin, reported from the "Quote items" screen while quotes are turned off:
+
+1. The "Turned off" callout above a list has no space below it and an empty rounded strip (the stats `<dl>` with no stats) sits between it and the list card.
+2. Screens whose feature is off in Settings -> Payment gateway (Orders, Quotes, Quote items, Shipping methods) still appear in the admin side menu. They must disappear from the navigation; opening one by URL keeps showing the callout.
+
+The framework has no request-time navigation visibility today (`pact.NavigationItem` is static and `cabana.Registry.Metadata` filters by permission only), so this adds one additive, non-breaking hook (`pact.NavigationItem.Visible`), uses it in the plugin, fixes the templates and adds the callout spacing in the admin CSS.
+
+Purpose: the admin shows menu entries for features the shop has turned off, and the feature-off screen looks broken.
+Output: two commits in `summercms.go` (framework hook with README/docs and a unit test; CSS fix) plus a dist rebuild commit, and one commit in `../sm-paymentgateway-plugin` (navigation, templates, README, test). No tag, push, deploy or submodule pointer bump.
+
+Hard limits: other Claude sessions work in `summercms.go`: stage by explicit path, never `git add -A`; do not touch `.planning/STATE.md`, `.planning/state.json`, `.msd/` or `.planning/phases/17-blog-companions/17-VERIFICATION.md`. No co-author tags. One logical change per commit. `sm-paymentgateway-plugin` is a core plugin: no breaking change to its exported API (every exported identifier listed in its README line 338 stays). Framework code and docs never name a consuming application.

+## Planning-time observations (2026-10-16, live)
+
+Edit scope rests on these facts; re-check the ones a task's precondition names before editing.
+
+- `summercms.go` working tree: only `.planning/STATE.md`, `.planning/state.json` (modified), `.msd/` and `.planning/phases/17-blog-companions/17-VERIFICATION.md` (untracked), all other sessions' files. Nothing uncommitted under `modules/`, `admin/` or `docs/`. `../sm-paymentgateway-plugin` is clean on its own repo (`go.work` replaces `git.golem15.com/golem15/summercms` with `../summercms.go`; its `go.mod` still requires a tagged framework, so the plugin can only bump that requirement after a framework release that contains this hook).
+- Baselines pass today: `go vet ./modules/pact ./modules/cabana && go test -short ./modules/pact ./modules/cabana` in the framework (cabana short suite 0.9 s); `go vet ./... && go test -short ./...` in the plugin. `summer` is NOT on PATH: use `go run ./cmd/summer docs:build --check`. `admin/node_modules` is present (no `npm ci` needed). Docker is available but nothing here needs it.
+- `pact.NavigationItem` (`modules/pact/capabilities.go:541`): `Code, Label, Icon, Permissions, Order, Controller, SideMenu`. `pact` already imports `context`. `pact.SettingsItem` carries func fields tagged `json:"-"` (`NewModel`), the convention to follow for a func field.
+- `cabana.Registry.Metadata(ctx, principal, tr)` (`modules/cabana/navigation.go:39`): drops a parent the principal cannot open, filters children by `Allows`, then `view.Controller = r.openableTarget(principal, item, children)`; `openableTarget` (line 101) keeps `item.Controller` when empty or `canOpen`, else the first child the principal can open, else "". The items come from `r.navigation`, collected once in `registry.go:313-320` (`validateNavigationShape`) and validated in `validateNavigation` (line ~405-445): codes, duplicate children, known controllers, known permissions. Neither looks at any other field, so a func field needs no validation change. `GET /navigation` is served from `http.go:498` with the request context.
+- The SPA loads navigation once per boot and after sign-in (`admin/src/state/useNavigation.ts` `loadNavigation`, called from `main.ts:30` and `LoginView.vue:33`); `railEntries` omits a plugin whose side menu is empty. `NavigationEntry` (cabana) is the JSON shape and does not change, so swag/OpenAPI are untouched.
+- Existing test to model on: `TestNavigationDropsDeniedParentAndRepointsTarget` (`modules/cabana/permissions_test.go:70`) builds `&Registry{byID: ..., navigation: ...}` directly with the `navController` helper (same file, line 62) and calls `reg.Metadata(context.Background(), principal, nil)`.
+- Docs that describe navigation and must stay truthful (`docs:build --check` validates every `pkg.Identifier` and `pkg.Type.Field` in prose): `modules/pact/README.md` line 27 (Features bullet) and line 122 (API table row); `modules/cabana/README.md` line 58 (Features bullet "Backend navigation ... filtered per user by `cabana.Registry.Metadata`") and the routes table row `GET /navigation, GET /settings` (line ~83); `docs/backend/users-and-permissions.md` line 67 (the paragraph after the Navigation example: "...navigation and settings entries are filtered by the permissions they name... links to its first openable side-menu entry instead"); `docs/backend/admin-controllers.md` "Compilation at boot" paragraph (line ~159: "compiles every plugin's controllers, settings, navigation and permissions once... Nothing is parsed per request"). The Go examples in those pages are `src=` copies of `modules/cabana/example_controller_test.go`: do not edit them (prose only), so `docs:sync` is not needed. `docs/plugins/registration.md` line 84 only lists the interfaces and stays true.
+- Plugin navigation (`../sm-paymentgateway-plugin/admin_navigation.go`): `Navigation()` lists five side items always and picks the top-level `Controller` at boot via `ordersEnabledAtBoot()` (app nil, no `*gorm.DB`, settings table missing, load error: all answer true). `p.application()` (`admin.go:34`) returns the booted `*backpack.App` (nil before Register). `Navigation()` is called once by `cabana.Activate` at boot; a closure stored in the item runs later, at request time, when the app is set. Settings: `models.LoadSettings(ctx, db)` returns `*models.Settings` with `OrdersEnabled`, `ShippingsEnabled`, `UseQuotes` (`models/settings.go:34-36`), `TableName()` `golem15_paymentgateway_settings`.
+- Feature-off rules used by the callouts today (keep the navigation identical to them): orders off when `!OrdersEnabled` (`controllers/orders_partials.go:126`); quotes and quote items off when `!OrdersEnabled || !UseQuotes` (`controllers/quoteables.go:73 quotesNotice`); shippings off when `!OrdersEnabled || !ShippingsEnabled` (`controllers/shippings.go:86`). Payments is never off.
+- Header templates (`controllers/<name>/_<name>_notice.htm` for quotes, quoteables, shippings; `_orders_stats.htm`; `_payments_stats.htm`): each renders the callout inside `{{- with .Notice -}}` and then ALWAYS `<dl class="summer-stats">` ranging over `.Stats` (`statsView{Notice *noticeView; Stats []statView}`, `orders_partials.go:52`). An empty `<dl>` is the empty strip from the screenshot. No plugin test pins the `<dl>`.
+- CSS: `.summer-callout { margin: 0; ... }` (`admin/src/styles/main.css:459`), `.summer-stats { margin: 0; ... }` (line 349), `.summer-partial` rules at line 214. `PartialHost.vue:79` wraps every rendered partial in `<div class="summer-partial" data-partial="header|hint|...">`; `ListView.vue:444` is `<section class="flex flex-col gap-5">`, so the partial wrapper already has 20px to the list card and the only missing space is inside the partial, between the callout and the strip. `.summer-callout` is also used by `admin/src/components/form/FormField.vue:71` (a field notice between the comment and the error list, outside any `.summer-partial`) and by the plugin's `_order_hint.htm` and `_payment_hint.htm` (callout is the last child of the hint). A rule scoped to `.summer-partial` and to a callout that a sibling follows touches none of them.
+- Plugin tests are all `package paymentgateway_test`; Go allows an internal `package paymentgateway` test file next to them, which is what a pure unexported visibility function needs. The plugin's short admin tests live in `admin_short_test.go`.
+- Commit naming precedent for quick tasks in both repos: `feat(quick-261016-nqk): ...`, `fix(quick-...)`, `chore(quick-261016-nqk): rebuild embedded admin dist`. The plan and summary are committed by the quick workflow, not by these tasks.

+Repo: /media/nvme/dev/golem15/summercms.io/summercms/summercms.go. One commit, `feat(quick-261016-s8x): pact.NavigationItem.Visible hides navigation entries at request time`, staged by the seven paths above.
+
+pact (`modules/pact/capabilities.go`): add the field `Visible func(ctx context.Context) bool` with the tag `json:"-"` to `NavigationItem`, after `SideMenu`. Doc comment on the field: nil means always listed; when set, cabana calls it on every navigation request with the request context, after the permission check, and leaves the entry out when it answers false; a main item hidden this way takes its side menu with it; it must be cheap, must not panic and should answer true when it cannot decide (no database yet). Extend the type's comment accordingly. pact stays dependency-free (a func field only; `context` is already imported).
+
+cabana (`modules/cabana/navigation.go`): in `Metadata`, after `Allows` passes for a main item, skip the item when `item.Visible != nil && !item.Visible(ctx)` (so a denied principal never runs plugin code). While walking `item.SideMenu`, after the child's `Allows` check, skip a child whose Visible answers false and record its `Controller` in a small set of hidden controllers (a local map keyed by controller ID, ignoring ""). Change the unexported `openableTarget` to take that set and to treat `item.Controller` as not usable when it is in the set, falling through to the existing loop over the (already visible and permitted) children, so a parent whose own controller is a hidden child's links to the first visible openable child and to "" when none is. Permission-denied children are not added to the set: the existing permission behaviour (parent keeps its controller when the principal can open it) is unchanged. Update the comments of `Metadata` and `openableTarget`. Do not touch `NavigationEntry`, registry validation, swag annotations or the SPA.
+
+Test (`modules/cabana/permissions_test.go`, directly after `TestNavigationDropsDeniedParentAndRepointsTarget`, same `Registry{byID, navigation}` and `navController` pattern, superuser principal so permissions are not the factor): `TestNavigationHidesInvisibleItemsAndRepointsTarget` covering (a) a side item with Visible false is absent from `SideMenu` while a sibling with nil Visible stays; (b) a parent whose Controller is that hidden child's controller gets the first visible openable child as `Controller`; (c) a parent with Visible false is dropped although every child is visible; (d) a parent whose only child is hidden and whose Controller is that child's keeps an empty SideMenu and an empty Controller; (e) Visible receives the context passed to Metadata (a `context.WithValue` key read inside the func). Use neutral names (`acme.shop.*`).
+
+Docs, same commit, prose only (the Go examples on these pages are `src=` copies and must not change): `modules/pact/README.md` line 27 bullet (add that a `pact.NavigationItem.Visible` func hides an entry at request time, nil = always listed) and line 122 row ("One backend navigation entry, with an optional side menu and an optional `Visible` func the admin runs on every navigation request."). `modules/cabana/README.md` line 58 bullet: add one sentence that an entry whose `Visible` func answers false for the request is left out like a denied one (a hidden main item with its side menu) and that a main item whose controller is a side item hidden this way links to its first visible openable side item; the `GET /navigation, GET /settings` row: "...the administrator may open and, for a navigation entry with a `Visible` func, that it answers true for the request". `docs/backend/users-and-permissions.md` line 67 paragraph: one sentence after "...links to its first openable side-menu entry instead." stating that a plugin can also hide an entry per request with `pact.NavigationItem.Visible` (for a screen whose feature is turned off in its settings) and that the same drop and relink rules apply. `docs/backend/admin-controllers.md` "Compilation at boot" paragraph: after "Nothing is parsed per request." add that the one run-time hook is `pact.NavigationItem.Visible`, which runs on every `GET /navigation` so a plugin can hide a screen whose feature is off; it must be cheap and answer true when unsure.

+  <action>
+Repo: /media/nvme/dev/golem15/summercms.io/summercms/summercms.go. Two commits: `fix(quick-261016-s8x): space below a callout that a sibling follows in a partial` (main.css only) and then `chore(quick-261016-s8x): rebuild embedded admin dist` (`modules/boardwalk/dist` only), both staged by path.
+
+In `admin/src/styles/main.css`, in the Callout block that starts at `.summer-callout` (line ~459, inside the same `@layer` block), add the rule `.summer-partial .summer-callout:not(:last-child) { margin-bottom: 12px; }` with a one-line comment that it spaces a callout from the stats strip (or any sibling) that follows it inside a rendered partial. Keep `.summer-callout { margin: 0 }` as is: the rule must not reach `FormField.vue`'s field notice (outside `.summer-partial`) nor change the order and payment hint partials, whose callout is the last child.
+
+Rebuild the embedded SPA with `npm --prefix admin run build` (node_modules is present; run `npm --prefix admin ci` only if `admin/node_modules` is missing) and commit `modules/boardwalk/dist` as the second commit.

+Repo: /media/nvme/dev/golem15/summercms.io/summercms/sm-paymentgateway-plugin (its own git repository). One commit there, `fix(quick-261016-s8x): hide feature-off screens from the navigation and drop the empty stats strip`, staged by the eight paths (relative to that repo). Do not bump any application's submodule pointer, do not change `go.mod`, do not push or tag.
+
+`admin_navigation.go`: add a pure unexported function, e.g. `navVisibility(s models.Settings)` returning the three booleans orders, quotes, shippings, with exactly the callout rules: orders = `s.OrdersEnabled`; quotes = `s.OrdersEnabled && s.UseQuotes`; shippings = `s.OrdersEnabled && s.ShippingsEnabled`. Add a method on `*Plugin` that loads the settings for one navigation request, e.g. `navSettings(ctx) (models.Settings, bool)`, with the same fallbacks the boot-time helper has today (nil app, no `*gorm.DB` in `app.Lookup`, settings table missing, load error or nil: not loaded), a 5 s timeout derived from the request context, and no logging. Set `Visible` on the orders, quotes, quoteables and shippings side items to closures that call it and answer true when the settings could not be loaded, else the matching rule; payments gets no Visible. The closures capture `p`, so they see the app that `Register` sets even though `Navigation()` runs at boot. Make the top-level item's `Controller` simply `controllers.OrdersControllerID` (cabana relinks it to Payments while orders are hidden) and delete the boot-time orders check and its now-unused imports, keeping the registered-controller filter. Rewrite the `Navigation` doc comment: the four feature items are listed while their feature is on, read per request, a change shows on the next navigation load without a restart, a screen opened by URL while off still shows the callout.
+
+`admin_navigation_test.go` (new, `package paymentgateway`, short, no Docker): `TestNavigationVisibility` with a table over `models.Settings{OrdersEnabled, UseQuotes, ShippingsEnabled}` combinations asserting the three rules (all on: all visible; orders off: all three hidden whatever the others; orders on and quotes off: quotes hidden, shippings visible; orders on and shippings off: shippings hidden, quotes visible), plus a check that `(&Plugin{}).Navigation()` yields one parent whose `Controller` is `controllers.OrdersControllerID`, whose `payments` side item has a nil Visible and whose other four side items have a non-nil Visible that answers true with `context.Background()` (the no-app fallback).
+
+The five header templates: wrap the `<dl class="summer-stats">` block, from the `<dl` line through `</dl>`, in `{{- if .Stats -}}` ... `{{- end -}}` so an empty stats list renders nothing after the callout. Keep everything else byte-identical.
+
+`README.md`: rewrite the navigation paragraph (line 122, "`Plugin.Navigation` adds ...") so it states that Orders, Quotes, Quote items and Shipping methods are listed only while their feature is on (`orders_enabled`; `orders_enabled` and `use_quotes`; `orders_enabled` and `shippings_enabled`), through a `Visible` func the admin runs on every navigation request, so a change shows on the next navigation load without a restart and every item is listed before the database is published or migrated; a screen opened by URL while its feature is off still shows the "Turned off" callout above its list; the top-level item opens Orders, or Payments while orders are off. Leave the partials table rows (lines 164-174) and the exported-API list (line 338) as they are; `Navigation` stays exported and its signature is unchanged.
+
+In the SUMMARY, note that the plugin now needs a framework release containing `pact.NavigationItem.Visible` before its `go.mod` requirement is bumped (development works through `go.work`), and that no application pointer was bumped.

+## Trust Boundaries
+
+| Boundary | Description |
+|----------|-------------|
+| browser (SPA) -> GET /navigation | A navigation request now runs plugin code (the Visible funcs) per request, after authentication and the permission check. |
+| plugin Visible func -> database | The payment gateway reads its settings row on every navigation request through the booted app. |
+| admin CSS -> every rendered partial | A global stylesheet rule reaches every plugin's partial trees. |

+|-----------|----------|-----------|----------|-------------|-----------------|
+| T-261016-s8x-01 | Information disclosure | cabana Metadata ordering | medium | mitigate | Visible runs only after `Allows` passes for the item (and for the parent), so a denied principal never triggers plugin code and a hidden entry leaks neither its label nor its controller; the new test and the existing permission test both stay green. |
+| T-261016-s8x-02 | Denial of service | plugin Visible on every GET /navigation | low | mitigate | The closure does one settings load with a 5 s timeout from the request context and answers true on any failure (no panic path, no retry); navigation is loaded once per SPA boot, not per screen. |
+| T-261016-s8x-03 | Elevation of privilege | hidden screen opened by URL | low | accept | Visibility is a menu concern: the controller's `RequiredPermissions` still guard every request and the screen keeps answering with the feature-off callout, exactly as before. |
+| T-261016-s8x-04 | Tampering | the margin rule reaching FormField.vue or the hint partials | low | mitigate | The rule is scoped to `.summer-partial` and to a callout that a sibling follows; FormField's notice is outside a partial and the hint callouts are last children; `check-admin-dist.sh` proves the committed dist is the one built from this CSS. |
+| T-261016-s8x-SC | Tampering | npm/Go dependency installs | low | accept | No new dependency in either repo; `npm --prefix admin run build` uses the installed node_modules from the committed lockfile; the plugin's go.mod is unchanged. No package-legitimacy checkpoint is needed. |

+# Quick 261016-s8x: Payment gateway banner bottom margin and feature-off screens hidden from the navigation Summary
+
+Added `pact.NavigationItem.Visible`, a per-request visibility hook honoured by `cabana.Registry.Metadata` (drop a hidden main item with its side menu or a hidden side item, relink a parent whose controller is a hidden child's to its first visible openable child), used it in the payment gateway so Orders, Quotes, Quote items and Shipping methods disappear from the admin menu while their feature is off in Settings -> Payment gateway, made the five header partials emit the `summer-stats` strip only when there are stats, and gave a callout 12px of space below it when a sibling follows it inside a rendered partial.

+
+## Framework release note for the plugin
+
+The plugin now compiles only against a framework that has `pact.NavigationItem.Visible`. Development works through the plugin's `go.work` replace (`../summercms.go`); its `go.mod` was left unchanged (still requires the last tagged framework) and must be bumped only after a framework release containing commit `06e2e60` is tagged. No application pointer was bumped.
+
+## What was built
+
+### Task 1: framework hook (`06e2e60`)
+
+- `pact.NavigationItem.Visible func(ctx context.Context) bool` (tag `json:"-"`), nil = always listed; field and type doc comments describe the contract (cheap, no panic, true when unsure, runs after the permission check, a hidden main item takes its side menu).
+- `cabana.Registry.Metadata`: skips a main item whose Visible answers false (after `Allows`); while walking the side menu skips a child whose Visible answers false after its `Allows` check and records its controller in a local `hidden` set; `openableTarget` now takes that set and treats `item.Controller` as unusable when it is in it, so the parent links to the first visible openable child, or "" when none.
+- `TestNavigationHidesInvisibleItemsAndRepointsTarget` covers: hidden side item absent while a nil-Visible sibling stays; parent repointed to the first visible openable child; parent with Visible false dropped although its child is visible; parent whose only child is hidden ends with empty SideMenu and empty Controller; Visible receives the context passed to Metadata.
+- Prose-only docs: pact README (Features bullet, API row), cabana README (Features bullet, `GET /navigation` route row), `docs/backend/users-and-permissions.md`, `docs/backend/admin-controllers.md`. The `src=` Go examples were not touched; `NavigationEntry`, registry validation, swag/OpenAPI untouched.
+
+### Task 2: callout spacing (`2dd5fb3`, `ab9f385`)
+
+- `.summer-partial .summer-callout:not(:last-child) { margin-bottom: 12px; }` next to the base `.summer-callout { margin: 0 }` rule (unchanged, still the only `.summer-callout {` rule).
+- `npm --prefix admin run build` and the rebuilt `modules/boardwalk/dist` committed; `scripts/check-admin-dist.sh`: "modules/boardwalk/dist matches a fresh build".
+
+### Task 3: plugin (`16484ba`)
+
+- `navVisibility(models.Settings) (orders, quotes, shippings bool)`: `OrdersEnabled`; `OrdersEnabled && UseQuotes`; `OrdersEnabled && ShippingsEnabled` (the callout rules).
+- `(*Plugin).navSettings(ctx) (models.Settings, bool)`: booted app -> `app.Lookup[*gorm.DB]` -> `HasTable` -> `models.LoadSettings`, 5 s timeout from the request context, no logging, false on every fallback.
+- `Visible` closures on orders, quotes, quoteables and shippings (true when settings cannot be loaded); payments has none; top-level `Controller` is `controllers.OrdersControllerID`; `ordersEnabledAtBoot` deleted; the registered-controller filter kept; `Navigation` doc comment rewritten.
+- The five header templates wrap the `<dl class="summer-stats">` block in `{{- if .Stats -}}` ... `{{- end -}}`; everything else byte-identical.
+- `admin_navigation_test.go` (`package paymentgateway`, short): `TestNavigationVisibility` with a six-case table over the settings flags and a shape check of `(&Plugin{}).Navigation()` (one parent opening Orders, payments nil Visible, the other four non-nil and true with `context.Background()`).
+- README navigation paragraph rewritten to request-time visibility; the partials table rows and the exported-API list are unchanged; `Navigation` stays exported with the same signature (no breaking change to this core plugin).
+
+## Verification (real output)
+
+Framework (`summercms.go`):
+
+- `go vet ./... && go test -short ./... -count=1`: exit 0, every package `ok`.
+- `go test -short ./modules/cabana -run 'TestNavigationHidesInvisibleItemsAndRepointsTarget|TestNavigationDropsDeniedParentAndRepointsTarget' -v`: both PASS.
+- `go test ./cmd/summer -run TestDocsTree -count=1`: ok.
+- `go run ./cmd/summer docs:build --check`: `docs:build: no problems found`.
+- `scripts/check-admin-dist.sh`: `check-admin-dist: modules/boardwalk/dist matches a fresh build`.
+- `git show --name-only HEAD` of `06e2e60` touches neither `admin/openapi` nor `modules/cabana/admin_openapi.go`.
+- `git status --porcelain -- modules admin docs`: empty (the other sessions' `.planning/STATE.md`, `.planning/state.json`, `.msd/`, `17-VERIFICATION.md` remain untouched and unstaged).
+
+Plugin (`sm-paymentgateway-plugin`):
+
+- `go vet ./... && go test -short ./... -count=1`: exit 0, every package `ok`.
+- `go test -short . -run TestNavigationVisibility -v`: PASS with 6 subtests.
+- Extra, beyond the plan: `go test . -run TestOrdersAdminSmoke -count=1` (Docker/testcontainers Postgres, not short): ok in 5.5 s. Its `navigation` subtest fetches `GET /navigation` through the booted app with `orders_enabled`, `shippings_enabled` and `use_quotes` on and still sees Orders, Quotes and Quote items for an `access_orders` admin, so the `Visible` closures and `navSettings` work against a live database.
+- 5 templates contain `{{- if .Stats -}}`; `grep -c 'Visible:' admin_navigation.go` = 4; README mentions `Visible`; `git diff --quiet HEAD -- go.mod go.sum`: unchanged; `git status --porcelain`: empty; `git tag --points-at HEAD`: empty.
+
+## Deviations from Plan
+
+None - plan executed exactly as written. (The Docker-backed smoke run above is an extra check, not a change.)
+
+## Deferred Issues
+
+Pre-existing, out of scope, logged in `deferred-items.md` next to this file: `gofmt -l` reports `modules/cabana/account_tokens.go`, `account_tokens_test.go`, `token_postgres_smoke_test.go`, `token_routes_test.go`, `token_scopes_test.go` (framework) and `mail_smoke_test.go` (plugin) as unformatted. None was touched.
+
+## Known Stubs
+
+None.
+
+## Threat Flags
+
+None beyond the plan's register: the only new run-time surface is the `Visible` call on `GET /navigation`, which the plan's T-261016-s8x-01/02 cover (runs after the permission check; one bounded settings load that answers true on failure).
+
+## State notes
+
+`.planning/STATE.md` and `.planning/state.json` were not modified: both carry other sessions' uncommitted edits and the task constraints say to leave them alone. ROADMAP.md was not touched (quick task). Docs artifacts (this SUMMARY, PLAN.md, deferred-items.md) are left uncommitted for the orchestrator's docs commit.
+
+## Self-Check: PASSED
+
+All listed files exist and commits 06e2e60, 2dd5fb3, ab9f385 (summercms.go) and 16484ba (sm-paymentgateway-plugin) are in history.

+| [cooler](modules/cooler/README.md) | Cache drivers and shared counters for SummerCMS: memory and Redis caches with a key prefix and TTLs, a Redis-backed rate-limit store, and the site-cache purge after admin saves. | The cool box you bring to the beach; it keeps things fresh and at hand for everyone in the group. |
 | [festival](modules/festival/README.md) | Typed, synchronous event bus with listener priorities, payload collection and stop-when-handled dispatch. | A summer festival announces events and the crowd reacts; it is the event bus. |
 | [fetchguard](modules/fetchguard/README.md) | Guarded outbound HTTP client and fetcher that blocks private and reserved addresses, enforces host, size and timeout limits, and offers an explicit trusted mode for operator-configured endpoints. | A lifeguard for outbound fetches; it watches every request the application sends out and stops the dangerous ones. |
 | [flare](modules/flare/README.md) | Web Push delivery with VAPID (RFC 8292) and aes128gcm payload encryption (RFC 8291) behind a small Pusher interface. | A signal flare reaches people far away; it sends Web Push notifications to browsers. |

Strings come from `GET <prefix>/api/v1/lang`, the `backend::lang` bundle with CLDR plural forms, in the administrator's chosen language (sent as `?locale=`) or else the request locale.
 
 Each record form makes a session key when it opens: 32 random bytes, base64url encoded. The form sends it in the `X-Session-Key` header with every file upload, file list and file removal, and with the final create or update save. Uploads and removals are deferred: the server holds them against the key and the admin, and the save that carries the same key commits them in its transaction. Until then the form counts as unsaved, so leaving it asks first, and a new record's files go to record id `0`. The form will not save while an upload is still in flight. Uploads use `XMLHttpRequest` for progress events and carry the same `X-Requested-With` header and cookie as every other call, plus an `X-Upload-Id` so a retry returns the already stored file. Files of a protected relation are fetched through the admin API with the key and shown from object URLs. The key travels only in headers, never in a URL.

Server validation errors show on their fields, and a successful save updates the name and the avatar in the top bar without a reload. See [My account](users-and-permissions.md#my-account) and [API tokens](users-and-permissions.md#api-tokens).
 
+The button at the top of the plugin rail switches the theme: each click moves from system (follow the browser's `prefers-color-scheme`) to light, to dark and back to system, and its icon and label name the current choice. The choice is saved for the signed-in administrator through `PUT <prefix>/api/v1/account/preferences` and comes back as `preferences.theme` in `GET .../auth/me`, so another browser shows the same theme after sign-in. The SPA also caches the last choice in `localStorage` (`summer-admin.theme`) and applies it before anything renders. When the save fails the previous theme returns with an error message. See [My account](users-and-permissions.md#my-account).

+When the server offers more than one admin language (`meta.locales` of `GET .../lang`), the user menu lists them under Language, each named in its own language.

 ## Types from OpenAPI
 
 The admin API is described by swag annotations in cabana. `scripts/check-admin-openapi.sh` generates the OpenAPI document (`admin/openapi/admin.json`) from them and the SPA's TypeScript types (`admin/src/api/schema.d.ts`) from the document, so the SPA's API client is checked against the server's shapes at compile time. Type overrides for swag live in the root `.swaggo` (it documents `json.RawMessage` as an untyped value, which swag cannot resolve on its own). `--check` fails when either committed file is out of date:

 - A duplicate id, a parent outside the set, a cycle and a node deeper than `maxDepth` are 422 `validation_failed` on `nodes`; a partitioned page without `partition` is a 422 on `partition`.
 - Otherwise the parent and sort columns of every node are written, without running the model's save hooks, and the answer is the new tree.
 
+The model's save hooks do not run on a reorder, and neither do the controller's `pact.FormAfterUpdate` hooks. A controller that has to react to a new order implements `pact.ReorderAfterSave`: `ReorderAfterSave(ctx, partition)` runs after every node was written, inside the same transaction (`cabana.TxFromContext` returns it), with the posted partition, or nil when the reorder has none. A returned error rolls the whole reorder back. The transaction is a `lagoon.Transaction`, so work registered with `lagoon.AfterCommit` runs only once the new order is committed; purging a site's page cache after a menu reorder is the typical case (`cooler.PurgeSiteCacheAfterCommit`, see [Site cache purge](../services/caching.md#site-cache-purge)).
+
 Both routes need the controller's permissions; the save is a write route (CSRF header, and a personal token needs a scope that allows POST).
 
 In the admin, a list whose schema carries `reorder` shows a "Reorder records" button before "New record". It opens the reorder page, and when the list is filtered on the partition column it opens that partition. The page shows the tree with a drag handle and move up, move down, outdent and indent buttons on every row. A row can also be dragged before, after or into another row (never into its own subtree), and the arrow keys on a focused handle move it the same way as the buttons. There is no Save button: 400 ms after the last move the page posts the whole set, shows "Order saved", and sends a pending save at once when the administrator leaves. Only one save is in flight at a time: moves made while it runs are sent after it settles, with the tree as it is then, so the stored order never ends older than the screen. A refused save puts the last saved order back, unless a later save is waiting (it carries the whole tree); a 409 reloads the tree. A save that settles after the page switched partition does not touch the new partition's tree. A partitioned page has a selector for the partition.

 An administrator's grants are the role's `permissions` merged with the administrator's own `backend_users.permissions`, the way WinterCMS merges them: the administrator's value for a code replaces the role's, and only `1` grants. A `-1` (or `0`) on the administrator therefore removes a permission the role grants, so rows copied from a WinterCMS database keep their denies. As in WinterCMS the merge compares codes exactly, so denying `acme.blog.access_posts` does not take it back from a role that grants `acme.blog.*`.

A changed password is hashed at `admin.password.bcrypt_cost` and ends every other session: tokens issued before the change are refused. The browser that made the change gets a fresh session cookie and stays signed in; an API client that used a Bearer token has to sign in again.
 - **Subtitle:** a short line such as a role or position. It is stored where WinterCMS keeps it, under the `subtitle` key of the jsonable `backend_users.metadata` column, so rows copied from WinterCMS keep their subtitles and other metadata keys survive a save. Code reads it with `cabana.BackendUser.Subtitle`, which treats NULL, `[]` and malformed metadata as no subtitle. `GET <prefix>/api/v1/auth/me` returns it as `subtitle`.
 - **Avatar:** `POST <prefix>/api/v1/account/avatar` takes one multipart part named `file_data`. Only jpg, jpeg, png, gif and webp images that pass the image check are accepted, up to `cabana.AvatarMaxBytes` (2 MiB) and within `http.body_limits.upload_bytes`; anything else answers 422 on `avatar`, and a body over the cap answers 413. The file is stored under a name the server generates, never the uploaded file name. An upload replaces the previous avatar: the old row is deleted with the new one's save and its files right after. `DELETE <prefix>/api/v1/account/avatar` removes the avatar and answers 200 also when there is none. The avatar is a public attachOne in `system_files` with attachment type `Backend\Models\User` (`cabana.BackendUserMorphType`) and field `avatar` (`cabana.BackendUserAvatarField`), exactly as WinterCMS stores it, so avatar rows copied from WinterCMS work as they are. `GET .../auth/me` returns its `url` and a 250x250 crop `thumb_url`, and the top bar shows it in place of the initials.
+- **Preferences:** the theme (system, light or dark) and the admin language an administrator picks in the SPA are saved through `PUT <prefix>/api/v1/account/preferences` and read with `GET <prefix>/api/v1/account/preferences`; `GET .../auth/me` returns them as `preferences`. The body may hold only `theme` and `locale` (`cabana.AdminPreferencesRequest`); any other key, including `id`, answers 422 on that key and nothing is written. Each present key is saved and an absent key keeps its value, so `{}` answers the current preferences. `theme` must be `system`, `light` or `dark`; `locale` must be `""` (follow the request locale) or one of the admin locales `GET /lang` lists in `meta.locales`; another value or a non-string answers 422 on that field. They are stored under `admin_theme` and `admin_locale` in `backend_users.metadata`, next to the subtitle; the defaults (`system`, `""`) are stored as absent keys, every other key survives a save, and metadata that is not a JSON object is never overwritten (422). Like the rest of My account the routes act only on the token's own administrator and refuse personal API tokens.
 - **API tokens:** a card below the profile form (never inside it — the page Save does not touch tokens) lists, creates and revokes only the signed-in administrator's own tokens. Creating asks for a name, an expiry (`30d`, `90d`, `365d` or `never`) and scopes from `GET /account/tokens/scopes`; the plaintext is shown once in the dialog for copying, then cleared. Revoke asks for confirmation. A "Show revoked tokens" toggle reloads the list with revoked rows. See [API tokens](#api-tokens) for the wire contract and scopes.
 
 Plugins that show an administrator, such as an author box, read the subtitle with `cabana.BackendUser.Subtitle` and the picture with `cabana.BackendUserAvatar`, which returns the avatar file (or nil) for an administrator id.

+The disk name's extension follows the content, not the client's name, because a web server or CDN in front of the bucket picks the Content-Type from the extension. `attach.DiskExtension` derives it from the sniffed type and the client's extension. For a specific type such as PNG, JPEG, PDF, MP3 or WebM, the client's extension is kept when it names that type, else the type's usual extension is used: a PNG uploaded as `x.html` (with `html` allowed) is stored as `<hex>.png`, and its URL ends in `.png`. For a generic sniff (plain text, HTML, XML, a zip container or unknown bytes) the client's extension is kept, so `report.docx` stays `.docx` and an HTML body uploaded as `note.txt` stays `.txt`, unless the extension is one a browser renders or runs (html, svg, xml, js, css, php and the like), which becomes `.txt` for text and `.bin` otherwise. `file_name` always keeps the client's name, so downloads still carry it.
 
 The content type is sniffed from the first bytes of the body, never taken from the client. `Limits.MIMETypes` narrows it further: an entry with a slash is a MIME pattern such as `image/png` or `image/*`, an entry without one is an extension, and a file that matches no entry returns `attach.ErrMIMEType`. `Limits.MaxBytes` is enforced while the body streams into the bucket; a body one byte over the limit returns `attach.ErrTooLarge` and leaves no blob and no row behind.

+## Cookie transport
+
+A browser frontend can keep the token in an httpOnly cookie instead of JavaScript-readable storage. The cookie attributes come from one block, `auth.cookie.*`, which `bouncer.LoadCookieConfig` reads into a `bouncer.CookieConfig` at boot:
+
+```yaml
+cookie:
+  domain: example.com
+  same_site: lax
+```
+
+This fragment belongs in `config/auth.yaml`. With the block unset the cookie is named `token`, has `Path=/`, `HttpOnly` and `SameSite=Lax`, no `Domain` (host-only) and `Secure` exactly when `app.url` is https. The keys:
+
+| Key | Default | Controls |
+|-----|---------|----------|
+| `auth.cookie.name` | `token` | Cookie name. |
+| `auth.cookie.domain` | empty (host-only) | A parent domain shares the cookie with its subdomains. |
+| `auth.cookie.path` | `/` | Cookie path. |
+| `auth.cookie.secure` | true when `app.url` is https | In the production environment a value that resolves to false is refused, whether `false` is set or inferred from an http or unset `app.url`. |
+| `auth.cookie.same_site` | `lax` | `lax`, `strict` or `none`; `none` requires Secure. |
+
+A `bouncer.CookieConfig` built by hand instead of through `bouncer.LoadCookieConfig` gets `SameSite=Lax` when `SameSite` is unset, and the zero config writes `token` on `/` with `HttpOnly`, `SameSite=Lax` and `Secure`; a config with any field set keeps its own `Secure` value.
+
+An invalid domain, `same_site: none` without Secure, or a cookie that is not Secure in production makes `bouncer.LoadCookieConfig` return an error naming the key. In production that covers `secure: false` and an unset `auth.cookie.secure` with an http or missing `app.url`; that error names `auth.cookie.secure` and `app.url`, and you fix it by setting `app.url` to the public https URL or `auth.cookie.secure: true`. Return the error from your plugin's boot so the application does not start with a cookie browsers would drop or send in clear.
+
+`bouncer.CookieConfig.TokenCookie` builds the cookie for a token and a lifetime. Pass the guard's refresh window (`refresh_ttl`, 20160 minutes by default), not its access `ttl`: the access token inside expires after `ttl`, the frontend's 401 handling then calls the refresh endpoint, and that endpoint needs the cookie to still be there. A cookie that died with the token would force a new sign-in every hour. `bouncer.CookieConfig.ForgetTokenCookie` builds the matching cookie that deletes it; it carries the same name, path and domain, or the browser would keep the original.
+
+`bouncer.CookieRefreshHandler` is a ready-made refresh endpoint. It reads the token from the cookie (only from the cookie), calls your refresh func, which wraps `bouncer.Refresh` or `bouncer.RefreshAudienceFor` and so rotates the token and blacklists the old `jti`, sets the rotated cookie and passes a `bouncer.CookieResult` to your writer, which answers in the application's own envelope. A missing cookie (`bouncer.ErrNoTokenCookie`) or a refused refresh reaches the writer with status 401 and leaves the cookie alone. `bouncer.CookieLogoutHandler` revokes the cookie's token through your revoke func, always clears the cookie and answers 200. The [bouncer README](../../modules/bouncer/README.md) has a complete example.
+
+**Subdomains.** For a frontend on `www.example.com` calling an API on `api.example.com`, set `auth.cookie.domain: example.com`, list `https://www.example.com` in the API's CORS origins with `supports_credentials: true` (see [Routing](routing.md#cors)), and send requests with credentials. A `Domain` cookie reaches every subdomain of `example.com`, so every host under it is inside the trust boundary: an application on another subdomain receives the token too. Keep the default host-only cookie when frontend and API share one host.
+
+**CSRF.** CORS controls who may read a response, not who may send a request. `SameSite=Lax` treats sibling subdomains as the same site, so a page on any `*.example.com` host can make the browser send the cookie. Mount the refresh and logout handlers on POST routes only, and for routes that act on the cookie prefer a JSON body or a custom header, which a cross-site form cannot send without a CORS preflight. The refresh answer is unreadable to an origin CORS does not allow, and a forced logout is the worst a cross-site POST to the logout route can do.
+
 ## Guards and middleware
 
 A guard implements `bouncer.Guard`: it turns a request into a principal or an error. `bouncer.NewJWTGuard` is the frontend guard. It reads the bearer token, then any cookie names you give it, verifies the token, checks the blacklist and the user's cutoff, and loads the user through your `bouncer.UserProvider`. On failure it answers 401 with `{"error":true,"message":...}`. `bouncer.NewBackendJWTGuard` is the same for the admin audience.

+## Turnstile
+
+[Cloudflare Turnstile](https://developers.cloudflare.com/turnstile/) keeps bots off guest and registration endpoints. The frontend widget produces a token, the request carries it, and the server checks it with Cloudflare's siteverify endpoint. surf registers the check as named middleware with two modes:
+
+| Middleware | Without a secret | With a secret |
+|------------|------------------|---------------|
+| `turnstile:open` | passes (a development no-op) | the token must verify |
+| `turnstile:closed` | 503 in the production environment, passes elsewhere | the token must verify |
+
+Use `turnstile:closed` where an unprotected endpoint would be a hole, such as guest entry: a production deployment that forgot the secret answers 503 instead of letting every bot in. Use `turnstile:open` where the endpoint has other protection and must keep working without Turnstile, such as registration. With a secret set both modes behave the same: a missing token, a token Cloudflare rejects, a token longer than 2048 characters, a failed siteverify call or one slower than 5 seconds answers 422.
+
+The middleware reads the token from the `turnstile_token` field (`turnstile.field` changes the name): the query string first, then a JSON object body or a form body. It reads the body and restores it, so the handler sees the same bytes. A multipart body is not searched; put the token in the query string there.
+
+| Key | Default | Controls |
+|-----|---------|----------|
+| `turnstile.secret` | empty | The site's secret key. Set it through `SUMMER_TURNSTILE__SECRET`; a PHP application's `TURNSTILE_SECRET` value moves to that variable. When it is empty and routes name `turnstile:open` or `turnstile:closed`, the start-up logs one warning, `surf: turnstile.secret is empty`, with the number of such routes, since they are then unprotected. |
+| `turnstile.field` | `turnstile_token` | The request field carrying the token. |
+
+Refusals are written with neutral bodies, `{"error":"turnstile_unavailable"}` (503) and `{"error":"turnstile_failed"}` (422). To keep an existing response envelope, publish a `bouncer.TurnstileWriter` on the app in your plugin's `Register`; it receives the status and the `bouncer.TurnstileVerdict`. A published `*bouncer.Turnstile` replaces the verifier built from config, for example to give it its own `http.Client`.
+
+Cloudflare's [testing page](https://developers.cloudflare.com/turnstile/troubleshooting/testing/) lists secrets that always pass (`1x0000000000000000000000000000000AA`) or always fail (`2x0000000000000000000000000000000AA`), for staging environments and manual checks. A token is valid for 300 seconds and only once: verify it before any write and never retry a verification with the same token.
+
+The middleware runs before the handler, so a request with both a bad token and invalid fields gets the Turnstile answer, not the validation errors. When a ported endpoint must keep the order it had, such as validating a name first, call `bouncer.Turnstile.Verify` from the handler instead of using the middleware: it takes the context, token, client IP and mode and returns the verdict, plus an error for logging that never contains the secret or the token.
+
 ## Passwords
 
 `bouncer.HashPassword` hashes with bcrypt at the cost you give it, `bouncer.CheckPassword` compares in constant time, and `bouncer.NeedsRehash` reports a hash made below your configured cost. WinterCMS stores bcrypt hashes too, so existing passwords keep working:

+WinterCMS and Laravel cache through the `Cache` facade: `Cache::get`, `Cache::put`, `Cache::remember` and friends, backed by the store `config/cache.php` selects. SummerCMS has the same core through [cooler](../../modules/cooler/README.md): one `cooler.Cache` per application, with an in-process driver by default and a Redis driver shared by every instance.

+| `Cache::put($key, $value, $ttl)` | `cooler.Cache.Set` stores bytes for a TTL. |

+| `Cache::increment($key, $by)` | `cooler.Cache.Increment`. |

+
+## Drivers
+
+`cache.driver` selects the driver:
+
+- `memory` (the default) keeps values in the process, in an otter cache bounded by `cache.memory.max_entries` (default 10000; `cooler.DefaultMaxEntries`). Beyond that, the least valuable entries are evicted, so keys derived from request data cannot grow memory without limit. Each instance has its own memory cache.
+- `redis` keeps values in Redis at `redis.url`, shared by every instance. When the rate limiter also uses Redis (`http.rate_limit.store: redis`, see [Rate limiting](rate-limiting.md#sharing-limits-across-instances)), both use one connection pool.
+
+```yaml
+# config/cache.yaml
+driver: redis
+```
+
+```yaml
+# config/redis.yaml (or SUMMER_REDIS__URL, which keeps a password out of YAML)
+url: redis://10.0.0.7:6379/0
+```
+
+A missing or malformed `redis.url`, an unknown driver name or a `cache.memory.max_entries` below 1 fails the start-up with an error that names the key; an error never shows the Redis URL. Redis being down at start-up is a warning, not a failed start.
+
+## Keys and the prefix
+
+Every key is stored as `<prefix>cache:<key>`. The prefix is `cache.prefix` when set; by default it is `app.name` lower-cased, with every run of characters other than letters and digits replaced by `_`, followed by `:`, so `app.name: Acme Blog` gives `acme_blog:` and the key `blog:popular` is stored as `acme_blog:cache:blog:popular`. With `app.name` empty the prefix is `summer:`. Rate-limit counters live under `<prefix>rl:`, so several applications, and the cache and the limiter of one application, can share a Redis without touching each other's keys.
+
+## TTLs
+
+A TTL of 0 or less keeps a value until it is forgotten, flushed or, in the memory driver, evicted. A positive TTL expires the value after that long; Redis stores it with millisecond precision. `cooler.Cache.Increment` starts a missing key at 0 without a TTL and keeps the expiry of an existing key, as Redis `INCRBY` does.
+
+## Remember degrades instead of failing
+
+`cooler.Cache.Remember` reads the key and, on a miss, calls the callback, stores its value for the TTL and returns it. When the cache itself fails, for example while Redis is down, it does not fail the page: a failed read still calls the callback and returns its value, a failed write is skipped, and both are logged as a warning at most once per minute. Only an error from the callback is returned. The other methods return cache errors to the caller.
+
+## Jobs and console commands
+
+The `serve` command installs cooler at start-up (`cooler.Install`) and publishes the cache on the application, so plugins and the in-process job worker find it with `app.Lookup[cooler.Cache]()`. Other commands, such as a dedicated `queue:work` process or a console command, do not run `serve`; they call `cooler.FromApp`, which returns the published cache or builds the configured one and publishes it. It does not connect at construction: the Redis driver dials on the first call, so a command that never touches the cache never needs Redis.
+
+## Flush
+
+`cooler.Cache.Flush` removes this application's cache keys and nothing else. The Redis driver walks `SCAN MATCH <prefix>cache:*` in batches of 500 and removes each batch with `UNLINK`; it never empties the whole Redis database, which would also drop rate-limit counters and other applications' keys. The memory driver empties the process cache.
+
+## Site cache purge
+
+A server-rendered site in front of the API usually caches its pages for a few minutes (a Nuxt `routeRules` `swr` window, for example). Without help, an edit in the admin shows on the site only when that window ends. cooler closes the gap: after an admin save commits, it queues a purge request to the site, and the site drops its route cache, so the next page view renders the change.
+
+Configure the target once for the application:
+
+| Key | Environment | Meaning |
+|-----|-------------|---------|
+| `site_cache.purge_url` | `SUMMER_SITE_CACHE__PURGE_URL` | The site's purge route, for example `http://127.0.0.1:3000/api/__site__/cache/purge`. |
+| `site_cache.purge_token` | `SUMMER_SITE_CACHE__PURGE_TOKEN` | The bearer token, at least 32 characters (`cooler.SiteCachePurgeMinTokenLength`). |
+
+Set both or neither; with neither, nothing is purged. The URL must be http or https with a host, without user info or a fragment, and plain http is accepted only for a loopback host (127.0.0.0/8, `::1`, `localhost`): the site normally runs on the same machine, and the token must not cross a network in clear. Use https for any other host. A wrong or half-set configuration stops `serve` at start-up with an error that names the key; neither errors nor log lines ever contain the token.
+
+### What a purge sends
+
+Each committed save queues a purge; the request looks like this:
+
+```http
+POST /api/__site__/cache/purge
+Authorization: Bearer <site_cache.purge_token>
+Content-Type: application/json
+
+{"kind":"faq","slug":"shipping"}
+```
+
+The kind names what was saved (a plugin picks it, for example `faq`, `menu`, `menu_entry`, `post` or `category`) and the slug which record; the site may log them. The site answers `{"purged": <n>}`, and cooler logs `cooler: site cache purged` with the kind, slug, status and count.
+
+At most one request is in flight per process (per purger). Saves committed while it is sent collapse into one follow-up request carrying the last kind and slug, because each purge clears the site's whole route cache: a bulk delete of fifty rows sends at most two requests. The log line of such a follow-up adds `coalesced` with the number of saves it stands in for besides its own.
+
+### Timing and failures
+
+`cooler.PurgeSiteCacheAfterCommit` registers the purge on the save's transaction through `lagoon.AfterCommit`. It is queued only after the commit, so a page view between the purge and the commit cannot re-cache the old content, and a save that fails or is rolled back sends nothing. Outside a transaction it is queued at once. Queuing never blocks: the admin request answers without waiting for the site, and a background worker sends the request.
+
+A purge never fails a save. Each request is bounded by `cooler.SiteCachePurgeTimeout` (2 s) and detached from the admin request's cancellation; an unreachable site, an error status or a timeout is logged as one `cooler: site cache purge failed` warning and the save answers as usual. Redirects are not followed: a 3xx answer is logged as a failed purge with its status, so the bearer token never goes to another URL and the POST never turns into a GET. Point `site_cache.purge_url` at the final URL.
+
+Because the purge is fire and forget, a test or a console command that wants to see its effect calls `cooler.SiteCachePurger.Wait`, which returns once nothing is queued or in flight (or when its context ends). `serve` waits for a queued purge on shutdown, up to the timeout plus one second, through `cooler.Handle.Close`.
+
+### Purging from a plugin
+
+The `serve` command publishes the purger at start-up (`cooler.Install`), and `cooler.SiteCacheFromApp` returns it, or builds it from the keys in commands and tests that do not run `serve`. An admin controller calls it from its after-save hooks, which run inside the save transaction, and takes that transaction from `cabana.TxFromContext`:
+
+```go src=modules/cooler/example_test.go#articlesController.purge
+// purge queues one site-cache purge for the saved article once the save
+// transaction commits (at once outside one); the save never waits for the
+// site. Without a purge configured the purger is nil and nothing is sent.
+func (c articlesController) purge(ctx context.Context, model any) error {
+	article, ok := model.(*Article)
+	if !ok {
+		return nil
+	}
+	tx, _ := cabana.TxFromContext(ctx)
+	cooler.PurgeSiteCacheAfterCommit(ctx, tx, cooler.SiteCacheFromApp(c.app()), "article", article.Slug)
+	return nil
+}
+```
+
+Each of `pact.FormAfterCreate`, `pact.FormAfterUpdate` and `pact.FormAfterDelete` calls it:
+
+```go src=modules/cooler/example_test.go#articlesController.FormAfterUpdate
+// FormAfterUpdate runs inside the update's transaction.
+func (c articlesController) FormAfterUpdate(ctx context.Context, model any) error {
+	return c.purge(ctx, model)
+}
+```
+
+A nil purger (no purge configured) does nothing, so the hooks need no configuration check. A tree or sortable list's reorder save runs `pact.ReorderAfterSave` the same way; see [Tree reorder](../backend/lists-and-filters.md#tree-reorder).
+
+### The site side
+
+The Nuxt layers of the core plugins (the Journal, menu and FAQ layers) each ship the same route, so a site that extends any of them has it:
+
+- `POST /api/__site__/cache/purge` removes every entry of Nitro's route cache (pages, their `_payload.json` and feeds) and answers `{"purged": <n>}`.
+- Its token is `runtimeConfig.siteCache.purgeToken`, set through `NUXT_SITE_CACHE_PURGE_TOKEN` to the same value as `site_cache.purge_token`. With a token shorter than 32 characters the route answers 404.
+- It answers 404 to any request that came through a reverse proxy (`X-Forwarded-For`, `X-Real-IP` or `Forwarded`), unless the site opts in with `NUXT_SITE_CACHE_ALLOW_PROXIED` (see [A purge URL on another host](#a-purge-url-on-another-host)), and 401 to a missing or wrong bearer token, compared in constant time.
+- Each layer also ships the route rule `'/api/__site__/**': { cache: false }`. Without it, a site rule such as `'/**': { swr: 300 }` would wrap the purge route in Nitro's cached handler, which answers from the cache without running the route.
+
+The three copies are byte-identical, so it does not matter which layer's copy Nitro picks.
+
+### A purge URL on another host
+
+When the site does not run on the backend's machine, `site_cache.purge_url` is an https URL on the site's host, for example `https://www.example.com/api/__site__/cache/purge`. The request then reaches Nuxt through the site's TLS-terminating proxy (nginx, Caddy, Traefik), which adds `X-Forwarded-For`, `X-Real-IP` or `Forwarded`, and the route refuses such requests by default with 404. Pair the https purge URL with `NUXT_SITE_CACHE_ALLOW_PROXIED=true` on the site (`runtimeConfig.siteCache.allowProxied`): the route then accepts proxied requests, and the bearer token is the only gate. Keep the token long and secret (the same value in `site_cache.purge_token` and `NUXT_SITE_CACHE_PURGE_TOKEN`), and keep the default, loopback and no flag, whenever the site runs next to the backend.
