Roadmap: SummerCMS (Go)

Overview

v1 ports the Płytarium (fonoteka) headless PHP backend to a single Go binary without vue-fonoteka-app or fonoteka-mcp noticing. The journey starts with the smallest possible kernel plus a day-one parity harness, proves the whole stack on one real endpoint (GET /_fonoteka/api/v1/genres) before any further kernel design, then broadens outward: full data-layer fidelity, the three-auth-group HTTP layer, the user plugin, OAuth2.1 for MCP/ChatGPT, the admin schema pipeline and its Vue SPA, jobs/realtime/search infrastructure, the 154-route API surface (split into two delivery slices), domain jobs and external integrations, and finally a cutover phase where the parity harness is green on all 154 routes and both real clients run unchanged against the Go backend.

Phases

Phase Numbering:

• Integer phases (1, 2, 3): Planned milestone work
• Decimal phases (2.1, 2.2): Urgent insertions (marked with INSERTED)

Decimal phases appear between their surrounding integers in numeric order.

• Phase 1: Framework kernel foundation - Config, plugin registry, event bus, container and CLI skeleton boot the summer binary (completed 2026-09-16)
• Phase 2: API parity harness bootstrap - Fixture recorder + replay-and-diff harness against the live PHP backend, built on the Phase 1 command kernel (completed 2026-09-17)
• Phase 3: First vertical slice — genres end to end - GET /_fonoteka/api/v1/genres passes the parity diff through every layer (completed 2026-09-17)
• Phase 4: CLI scaffolding, i18n and mail - Scaffolding commands, translated/pluralized strings, mail templates (completed 2026-09-18)
• Phase 5: Data layer full fidelity - All 25 models and their squashed migrations with fillable/hidden/cast/soft-delete discipline (completed 2026-09-18)
• Phase 6: HTTP routing, auth groups and rate limiting - Three auth groups, named rate buckets, OAuth-safe middleware structure
• Phase 7: User plugin and authentication - Registration, login, JWT, organizations, personal tokens, must-change-password
• Phase 8: OAuth2.1 authorization server - zitadel/oidc server for fonoteka-mcp and the ChatGPT connector
• Phase 9: Backend admin authentication and schema pipeline - Admin roles, fields.yaml/columns.yaml, relation manager
• Phase 10: Admin Vue SPA - Login, navigation, lists, forms and relation manager for five controllers
• Phase 11: Jobs, realtime and search infrastructure - River, Centrifugo and Typesense sync brought up before the API phases that need them
• Phase 12: Płytarium API — Collections and Albums - Core content endpoints ported with byte-level parity
• Phase 13: Płytarium API — wishlist, notifications, CSV, credentials, public routes - Remaining core API surface
• Phase 14: Domain jobs and external integrations - CSV/Discogs jobs, wishlist digest, reindex, Discogs client, AI recognition, feedback, sitemap
• Phase 15: Cutover - Parity harness green on all 154 routes, both real clients run unchanged

Phase Details

Phase 1: Framework kernel foundation

Goal: The summer binary boots from layered YAML config, plugins self-register through one required interface plus optional capability interfaces, a typed event bus and service registry are available, and a CLI command framework with a dev watch loop exists — built only as far as the first vertical slice will need it, per the interleaved-not-sequential kernel approach. Mode: mvp Depends on: Nothing (first phase) Repos: summercms.go Requirements: KERN-01, KERN-02, KERN-03, KERN-04, KERN-05, KERN-06, KERN-07, KERN-08, KERN-09, CLI-01 Success Criteria (what must be TRUE):

1. summer build regenerates the blank-import plugin list and produces a binary that boots from a layered YAML config (base files, env overlay directory, per-plugin namespace, environment variables) with dot-path access.
2. A throwaway plugin registered via the Plugin interface has its Register phase run for all plugins before any Boot phase runs, in Requires()-topological order, verified by a test with reordered input.
3. A plugin can type-assert an optional capability interface (e.g. HasModels) and skip integration with another plugin that isn't registered, with no hard import.
4. The typed event bus supports fire-and-forget, fire-and-collect, and fire-until-handled dispatch, exercised by unit tests; per-request state travels only through context.Context, never a package-level global.
5. The summer CLI discovers a registered command and renders rich output (spinner, progress, table, prompts) with non-TTY degradation, and a dev watch loop rebuilds and restarts the binary on source change.

Plans: 4 plans

Plans: Wave 1

• 01-01-PLAN.md — Build and boot the separate hello app through the shared command kernel

Wave 2 (blocked on Wave 1 completion)

• 01-02-PLAN.md — Add layered config, optional plugin composition, services and typed events

Wave 3 (blocked on Wave 2 completion)

• 01-03-PLAN.md — Add plugin scaffolding, rich output and the watch rebuild loop

Wave 4 (blocked on Wave 3 completion)

• 01-04-PLAN.md — Complete unit, integration and race-enabled verification

Phase 2: API parity harness bootstrap

Goal: A fixture recorder captures request/response pairs from the running PHP backend — including real Nuxt and MCP flows — and a replay-and-diff harness with a normalizer for nondeterministic fields can run against any HTTP backend. The recorder and replayer are summer parity:* commands on the Phase 1 command kernel (bonfire); recording itself only needs a running PHP backend, but the tooling waits for Phase 1. Mode: mvp Depends on: Phase 1 Repos: summercms.go, fonoteka.go Requirements: QA-01, QA-02, QA-03 Success Criteria (what must be TRUE):

1. The fixture recorder captures a request/response pair from the live PHP backend for at least one route and stores it as a replayable fixture.
2. The replay-and-diff harness runs a recorded fixture against an arbitrary httptest.Server backend and reports a byte-level diff.
3. The harness's normalizer and assertions explicitly catch the parity classes named in research (nil vs [], date format, tri-state booleans, envelope/conditional keys) on a synthetic test case, not just status codes.
4. go vet and go test ./... are green, and the harness's own integration tests run against testcontainers Postgres.

Plans: 5 plans

Plans: Wave 1

• 02-01-PLAN.md — Record and replay one fixture through the summer CLI

Wave 2 (blocked on Wave 1 completion)

• 02-02-PLAN.md — Capture safe proxy sessions and manifest routes with strict diffs

Wave 3 (blocked on Wave 2 completion)

• 02-03-PLAN.md — Record all 154 PHP routes and real Nuxt/MCP flows

Wave 4 (blocked on Wave 3 completion)

• 02-04-PLAN.md — Wire honest Go replay with testcontainers Postgres

Wave 5 (blocked on Waves 1–4 completion)

• 02-05-PLAN.md — Complete contract, security and integration tests

Phase 3: First vertical slice — genres end to end

Goal: GET /_fonoteka/api/v1/genres passes the parity diff end to end (config → DB → plugin registry → JWT-guarded routing → GORM → JSON), proving every kernel layer together before any further kernel abstraction. Touches the JWT auth guard on the request path — treat as security-load-bearing and apply the security-review agent even though the guard is a throwaway seeded-token implementation at this stage. Mode: mvp Depends on: Phase 1, Phase 2 Repos: summercms.go, fonoteka.go Requirements: DATA-01, DATA-02, HTTP-01, HTTP-02, QA-04 Success Criteria (what must be TRUE):

1. GORM connects to Postgres over one shared *sql.DB (pgx stdlib); a gormigrate migration set runs up and down for a single plugin with per-plugin version tracking, and AutoMigrate is not the schema source.
2. A plugin registers a route group on net/http ServeMux with typed params, and a request is served through the full middleware pipeline (recover, CORS, locale, auth group, must-change-password, org context, rate limit, handler).
3. A JWT-guarded GET /_fonoteka/api/v1/genres route returns a real Genre row read from Postgres.
4. The response is diffed byte-for-byte against a fixture recorded from the live PHP backend using the Phase 2 harness, and the diff is green.

Plans: 4 plans

Plans:

Wave 1

• 03-01-PLAN.md — Boot the Postgres-backed JWT genre route through both plugins

Wave 2 (blocked on Wave 1 completion)

• 03-02-PLAN.md — Port active-collection counts, validation and Polish ordering

Wave 3 (blocked on Wave 2 completion)

• 03-03-PLAN.md — Add typed params, isolated rollback and the first real parity pass

Wave 4 (blocked on Wave 3 completion)

• 03-04-PLAN.md — Complete unit, integration and security verification

Phase 4: CLI scaffolding, i18n and mail

Goal: Scaffolding commands generate compiling stubs for every plugin artifact type, and plugins can register translated, CLDR-pluralized, namespaced strings and mail templates rendered through a pluggable driver interface. Mode: mvp Depends on: Phase 1 Repos: summercms.go Requirements: CLI-02, I18N-01, I18N-03 Success Criteria (what must be TRUE):

1. summer make:plugin, make:model, make:migration, make:command, make:job and make:admin-controller each generate stubs that compile and pass go vet.
2. A translation key vendor.plugin::group.key resolves for pl and en, including a CLDR plural form, loaded from per-plugin per-locale YAML files with parameter substitution.
3. A plugin registers a mail template and layout by dotted name with the per-locale suffix convention, and it renders via html/template through a driver interface (SMTP via go-mail) in a test send.

Plans: 4 plans

Plans:

Wave 1

• 04-01-PLAN.md — Generate compiling plugin artifacts, registry and model import checks

Wave 2 (blocked on Wave 1 completion)

• 04-02-PLAN.md — Load namespaced translations, plurals, parameters and locale fallbacks

Wave 3 (blocked on Wave 2 completion)

• 04-03-PLAN.md — Register, render and send plugin mail through pluggable drivers

Wave 4 (blocked on Wave 3 completion)

• 04-04-PLAN.md — Verify scaffolding, translation and mail with unit and SMTP integration tests

Phase 5: Data layer full fidelity

Goal: All 25 Płytarium models and their squashed migration set are ported with matching relations, casts, hooks, and the fillable/hidden/encrypted-cast mass-assignment and serialization discipline. This is security-load-bearing — mass-assignment boundaries and encrypted-at-rest credential casts are named security invariants in the PHP source — apply the security-review agent and the DTO-vs-model convention from the first model onward. Mode: mvp Depends on: Phase 1, Phase 3 Repos: summercms.go, fonoteka.go Requirements: DATA-03, DATA-04, DATA-05, DATA-06, DATA-07, DATA-08, DATA-09, DATA-10, DATA-11, CLI-03 Success Criteria (what must be TRUE):

1. All 25 models exist with matching table names, columns, indexes and defaults, and every Go migration runs up and down individually; the final schema matches PHP's (migrations are squashed per final-state table, not a 1:1 port of PHP's 38 files — the historical migration count is not a target). summer migrate:rollback --plugin=fonoteka rolls back only that plugin's last migration.
2. A many-to-many relation with pivot business columns (album_artists.sort_order, CollectionEditor.role/granted_at/granted_by) round-trips correctly for a 3+ artist album; belongsTo/hasOne/hasMany relations return ordered results.
3. The fill boundary of the PHP write services (at minimum Album, Collection and the four credential models) is fuzzed against real Postgres with random extra and server-owned keys, asserting nothing outside the allow-list is persisted (service-level, this phase); a request-DTO-level fuzz over every write endpoint is Phase 12's criterion (the HTTP layer does not exist until Phase 6/12). Serialization honors the hidden deny-list with an explicit per-call override.
4. The money cast round-trips the PHP ceiling and blank-string cases as a fixed 4-decimal JSON string (never float64), and an encrypted-at-rest credential column is AES-GCM encrypted at rest and hidden from serialization.
5. Paginated responses use the exact {data, meta{current_page,last_page,per_page,total}} envelope with no links key; another plugin extends a model's lifecycle through the GORM callback registry and a companion migration without editing the owning plugin's file; soft-deletable + uniquely-keyed tables pass a delete-then-recreate test.

Plans: 6 plans

Plans: Wave 1

• 05-01-PLAN.md — Verify models-leaf rule, restructure plugins into Winter layout, ship lagoon write/read-path primitives

Wave 2 (blocked on Wave 1 completion)

• 05-02-PLAN.md — Album/Collection slice: migrations, models, casts, validation engine, write services

Wave 3 (blocked on Wave 2 completion)

• 05-03-PLAN.md — Secrets slice: encrypted cast, key management, organisations, credentials/OAuth tables
• 05-04-PLAN.md — Attachments: system_files, blob storage, thumbnails, delete lifecycle

Wave 4 (blocked on Wave 3 completion)

• 05-05-PLAN.md — Remaining models, D-02 schema-diff proof, test-only DATA-11 fixture plugin, CLI-03 verification

Wave 5 (blocked on Wave 4 completion)

• 05-06-PLAN.md — Fuzz tests, hidden-marshal coverage, attachment smoke test, security review

Phase 6: HTTP routing, auth groups and rate limiting

Goal: The three mutually exclusive auth groups (JWT, personal token, public/onboarding) share handlers with correct route subsets, named rate-limit buckets are ported 1:1, and OAuth/RFC routes are structurally exempted from any house envelope or error middleware. Security-load-bearing — auth guard registry, rate limiting and the SSRF-guarded outbound fetch helper all live here; apply the security-review agent. Mode: mvp Depends on: Phase 3, Phase 5 Repos: summercms.go, fonoteka.go Requirements: HTTP-03, HTTP-04, HTTP-05, HTTP-06, HTTP-07, HTTP-08, HTTP-09 Success Criteria (what must be TRUE):

1. The same handler serves both a JWT-authenticated request under /_fonoteka/api/v1 and a personal-token request under /api/v1/fonoteka, with public/onboarding groups reachable without auth; unknown and malformed ids on ownership-scoped resources both return 404.
2. All seven named rate-limit buckets are enforced with the documented keys and limits, including a route stacking two limiters.
3. Response conventions hold under test: empty arrays serialize as [], timestamps carry +00:00, tri-state booleans keep null, conditional keys are omitted not nulled; an OAuth-group route carries no house envelope or error middleware, verified by route-registration inspection.
4. The guarded outbound fetch helper rejects a non-allow-listed host and enforces a byte cap and timeout on a user-supplied cover URL fetch (manual cover URL, Discogs cover).
5. OpenAPI is generated from swaggo/swag annotations on handlers and openapi-typescript produces valid TypeScript types from it; CORS and JSON body-size limits match the PHP deployment.

Plans: TBD

Phase 7: User plugin and authentication

Goal: The user plugin is ported with registration, login, JWT issue/refresh, organizations, personal API tokens and the must-change-password lock. Security-load-bearing — password auth, token scope ceilings and the session lock all live here; apply the security-review agent. Mode: mvp Depends on: Phase 6 Repos: summercms.go, fonoteka.go Requirements: AUTH-01, AUTH-02, AUTH-03, AUTH-04, I18N-02 Success Criteria (what must be TRUE):

1. A user can register, log in, log out, reset a forgotten password by email, verify email, and receive/refresh a JWT (golang-jwt) with the same claims and cookie behavior the Nuxt app expects.
2. Organization fields appear on the user payload through a fire-and-collect event the fonoteka plugin populates, without the user plugin importing fonoteka.
3. A personal API token is created with a read|write|ai scope ceiling, listed, and revoked; a scope-checking middleware rejects an out-of-scope request.
4. The must-change-password flag returns 423 on the authenticated surface except the locale and password-change routes, and locale resolves per request from the user's persisted preferred_locale with header fallback even while the lock is active.

Plans: TBD

Phase 8: OAuth2.1 authorization server

Goal: An RFC 8414/6749/7591-compliant OAuth2.1 server on zitadel/oidc serves fonoteka-mcp and the ChatGPT connector unchanged, including exact WWW-Authenticate and protected-resource-metadata headers. Security-load-bearing — bearer tokens, PKCE and constant-time secret comparison all live here; apply the security-review agent. Mode: mvp Depends on: Phase 6, Phase 7 Repos: summercms.go, fonoteka.go Requirements: AUTH-05, AUTH-06, AUTH-07 Success Criteria (what must be TRUE):

1. RFC 8414 metadata is served unenveloped at its well-known path; authorize with PKCE and a consent screen works, and the token endpoint issues/refreshes authorization_code and refresh_token flows, all as unwrapped RFC 6749 bodies with the PHP cache headers (Cache-Control: no-store, Pragma: no-cache).
2. RFC 7591 dynamic client registration and RFC 8707 resource parameter tolerance both work against a real client registration call.
3. A 401 on a protected route carries the exact WWW-Authenticate and protected-resource-metadata header contract, verified against fonoteka-mcp's actual discovery flow, not just a Go unit test.
4. Connected apps can be listed and revoked; OAuthClient/OAuthAuthCode/OAuthRefreshToken models persist correctly; fonoteka-mcp completes its install and auth flow unchanged; client-secret comparison uses crypto/subtle.ConstantTimeCompare.

Plans: TBD Research flag: yes

Phase 9: Backend admin authentication and schema pipeline

Goal: Backend admin users with roles are separate from frontend users and gate navigation and controller access; fields.yaml/columns.yaml drive a JSON form/list schema, including a first-class relation-manager schema replacing the one partial field. Security-load-bearing — separate admin authentication and permissions registry live here; apply the security-review agent. This is also the least-precedented design surface in the research (one real relation-manager usage in the PHP source, no direct library equivalent). Mode: mvp Depends on: Phase 5, Phase 6 Repos: summercms.go, fonoteka.go Requirements: AUTH-08, ADMIN-01, ADMIN-02, ADMIN-03, ADMIN-04, ADMIN-05 Success Criteria (what must be TRUE):

1. A backend admin user with a role logs in separately from frontend users, and navigation/controller access is gated by the permissions registry.
2. fields.yaml for a real controller parses (goccy/go-yaml) into a JSON form schema covering text, textarea, checkbox, switch, dropdown (model-method options) and relation (nameFrom, emptyOption), with span/tabs/context/attributes layout hints.
3. columns.yaml parses into a JSON list schema with searchable/sortable/relation columns and datetime/switch renderers.
4. The relation-manager schema supports search/link/unlink/manage-or-view lists for Collections' editors tab, replacing the partial field entirely.
5. Admin CRUD endpoints expose listExtendQuery/formExtendQuery/formBeforeCreate/formBeforeUpdate/relationExtendManageQuery hooks, bulk delete runs each record's lifecycle hooks, and the Settings model binds to a settings screen through the same schema pipeline.

Plans: TBD Research flag: yes

Phase 10: Admin Vue SPA

Goal: A minimal Vue 3 + TypeScript admin SPA renders login, permission-gated navigation, lists, forms and the relation manager for Albums, Artists, Collections, Genres and Styles, typed from the generated OpenAPI document. Mode: mvp Depends on: Phase 9 Repos: summercms.go, fonoteka.go Requirements: ADMIN-06 Success Criteria (what must be TRUE):

1. An admin logs in through the SPA and sees only the navigation items their permissions allow.
2. Each of the five controllers (Albums, Artists, Collections, Genres, Styles) renders a working list and form generated from its JSON schema.
3. The Collections form's relation manager lets an admin search, link and unlink an editor.
4. API calls in the SPA use TypeScript types generated from the OpenAPI document, with no hand-maintained duplicate type.

Plans: TBD UI hint: yes

Phase 11: Jobs, realtime and search infrastructure

Goal: River jobs run on the correct dual-driver split, Centrifugo publishing and channel authorization match the existing server, and Typesense sync stays a re-gated pre-filter — all brought up before the API phases that depend on them (album search needs Typesense sync, CSV import needs River jobs, notifications need the realtime publisher). River's dual-driver split and the Centrifugo/Typesense contracts are the least-implemented-and-verified parts of this research pass. Mode: mvp Depends on: Phase 5, Phase 7 Repos: summercms.go, fonoteka.go Requirements: JOBS-01, CLI-04, CLI-06, RT-01, RT-02, RT-03, SRCH-01 Success Criteria (what must be TRUE):

1. River runs on the shared *sql.DB (riverdatabasesql, transactional enqueue) with a separate riverpgxv5 client for LISTEN/NOTIFY dispatch, verified by a timed test that job pickup is not poll-interval latency; job outcomes (complete, fail, skip) are queryable through a job manager service.
2. The queue worker runs via summer queue:work and the scheduler runs recurring commands via summer schedule:run.
3. The websockets plugin issues connection and subscription JWTs and publishes to the existing Centrifugo server with the same secret, claims and channel names, served at GET /api/realtime/token.
4. A channel-namespace authorizer registry re-validates on every subscribe; a broadcastable model interface with bulk-write suppression emits exactly one summary event for a bulk operation.
5. Typesense sync is scoped by collection_id behind a settings kill-switch and degrades gracefully without DB/config.

Plans: TBD Research flag: yes

Phase 12: Płytarium API — Collections and Albums

Goal: Collections and Albums endpoints are ported with byte-compatible request/response shapes, including active-context switching, editor invitations, ratings, reservations, cover handling and search. Mode: mvp Depends on: Phase 5, Phase 6, Phase 7, Phase 11 Repos: fonoteka.go Requirements: API-01, API-02 Success Criteria (what must be TRUE):

1. Collections CRUD, the me/context active-collection switch (returning an opaque channel name), editor invitation/acceptance, share-link regeneration and public token views all pass the parity diff.
2. Albums CRUD, ratings, reservations, photo upload, manual cover URL and Discogs cover price all pass the parity diff.
3. Album search treats Typesense results as a pre-filter re-gated in SQL, verified by a security test that a stale/mis-scoped search document cannot leak an unauthorized result.
4. Artists/genres/styles lookup endpoints used by the Albums UI pass the parity diff.
5. A request-DTO-level fuzz over every write endpoint asserts unknown and server-owned keys are never persisted (inherits the HTTP half of Phase 5 criterion 3; the HTTP layer does not exist until Phase 6/12).

Plans: TBD

Phase 13: Płytarium API — wishlist, notifications, CSV, credentials, public routes

Goal: The remaining core API surface — wishlist, notifications, CSV import/export, per-user/org credentials, and onboarding/public/invitation routes — is ported with byte-compatible shapes and their own public rate-limit buckets. Mode: mvp Depends on: Phase 11, Phase 12 Repos: fonoteka.go Requirements: API-03, API-04, API-05, API-06, API-07 Success Criteria (what must be TRUE):

1. Wishlist items, subscriptions, public-wishlist/{token} views and purchase/digest triggers pass the parity diff.
2. Notifications list/mark-read/prune endpoints pass the parity diff (the realtime token endpoint itself is owned by the websockets plugin, ported in Phase 11).
3. CSV import runs as a multi-step session (store, show/poll, mapping patch, per-row edit, commit, cancel) and CSV export works on both authenticated groups, all passing the parity diff.
4. Per-user and per-org Discogs/AI credentials CRUD store encrypted values, honor the org-lock flag, and resolve env-to-org-to-user correctly.
5. Onboarding, public and invitation-inspection routes are reachable without auth and enforce their own public rate-limit buckets.

Plans: TBD

Phase 14: Domain jobs and external integrations

Goal: The domain-specific River jobs (CSV import write, Discogs match, wishlist digest), the reindex command, the Discogs client and AI cover recognition are ported on top of the Phase 11 jobs/realtime/search infrastructure and the Phase 13 API surface they serve. Mode: mvp Depends on: Phase 11, Phase 13 Repos: fonoteka.go (plus summercms.go only if a framework helper is needed) Requirements: JOBS-02, JOBS-03, SRCH-02, INTG-01, INTG-02, API-08, CLI-05 Success Criteria (what must be TRUE):

1. The CSV import write job and the self-redispatching Discogs match job (240s timeout, self-redispatching with a delay on a Discogs rate-limit error) both complete correctly.
2. The wishlist digest job coalesces a 30-minute window and deletes its queue row on completion.
3. The reindex command asserts zero collection_id-0 documents before and after and can drop the legacy index.
4. The Discogs client enforces its proactive rate threshold, bounded wait budget, retry-after fallback and host-locked cover fetch.
5. AI cover recognition works through both Anthropic and OpenAI-compatible adapters with per-credential model/base-URL overrides.
6. Feedback submissions and sitemap output work; the ported oauth-client/prune-notifications/reindex commands all run correctly.

Plans: TBD

Phase 15: Cutover

Goal: The parity harness is green on all 154 routes and vue-fonoteka-app and fonoteka-mcp run unchanged against the Go backend in daily use — the project's definition of done. Mode: mvp Depends on: Phase 2, Phase 8, Phase 9, Phase 10, Phase 12, Phase 13, Phase 14 Repos: fonoteka.go, summercms.go Requirements: API-09, QA-05 Success Criteria (what must be TRUE):

1. All 154 routes are registered on the correct auth groups with identical paths, methods and status codes.
2. The parity harness runs green across recorded fixtures for all 154 routes.
3. vue-fonoteka-app runs unchanged against the Go backend for a full manual session (browse, edit, upload, invite, OAuth-connect an MCP client).
4. fonoteka-mcp completes its install/auth flow and a representative set of tool calls unchanged against the Go backend.

Plans: TBD
