+# Phase 3: First vertical slice — genres end to end Verification Report
+
+**Phase 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.
+**Verified:** 2026-09-17T18:49:25Z
+**Status:** passed
+**Re-verification:** No — initial verification
+
+Must-haves are the four ROADMAP success criteria (they override plan-level truths). Plan `must_haves` were checked as supporting evidence. The ROADMAP goal is an infrastructure/API outcome, not a user-story sentence; MVP user-flow coverage is mapped from Plan 01's objective below.
+
+`03-REVIEW.md` status is `issues` (7 warnings, 0 critical). Those findings do not break must-haves or the phase goal and are recorded as non-blocking notes. `03-SECURITY-REVIEW.md` reports `threats_open: 0`.
+
+## User Flow Coverage
+
+User story (Plan 01 objective): «As a Fonoteka user with a valid token, I want to request the seeded genre list from a real Postgres backed Go app, so that the first complete config → plugin → DB → auth → HTTP path exists.»
+
+| Step | Expected | Evidence | Status |
+|------|----------|----------|--------|
+| Present a valid HS256 JWT for a persisted user | Guard loads the user; missing/forged tokens never reach the handler | `bouncer/jwt.go` `Verify` + `Middleware`; app `TestGenreListBehindJWT`, `TestGenreSecurityBoundaries` | ✓ |
+| Request `GET /_fonoteka/api/v1/genres` | Named pipeline (`jwt.auth`, `inv.must-change-password`) on ServeMux | `plugins/golem15/fonoteka/plugin.go` `Routes`; `surf.Assemble` | ✓ |
+| See the global genre list | Dedicated DTO `id`/`name`/`slug`/`album_count` under `data`, empty list `[]` | `genre_handler.go` `GenreAggregate` / `GenreList`; tenant counts from GORM | ✓ |
+| Outcome | Recorded PHP fixture diffs green; 153 other routes stay pending | This session: `TestParityCorpus` `recorded 154/154 passing 1 failing 0 unrecorded 0 pending 153`; `GET /_fonoteka/api/v1/genres jwt` PASS 0.09s | ✓ |
+
+## Goal Achievement
+
+### Observable Truths
+
+| # | Truth | Status | Evidence |
+|---|-------|--------|----------|
+| 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 | ✓ VERIFIED | `lagoon.Open`/`Use` open `sql.Open("pgx", dsn)` then `gorm.Open(postgres.New({Conn: sqlDB}))` and fail if `gdb.DB() != sqlDB`. `Publish` stores both handles on backpack. Per-plugin history tables `summer_migrations_<id>`. `RollbackLast` calls `gormigrate.RollbackLast()` for one plugin. This session: `go test ./lagoon -count=1` ok 7.940s (`TestSharedSQLPoolUsedByGORMAndClosed`, `TestTwoPluginMigrationSetsIsolated`, `TestNoAutoMigrate`). App: `TestMigrateSeedsCanonicalGenres`, `TestRollbackLastIsolatesFonoteka`, `TestPluginMigrationsDoNotUseAutoMigrate`. River listener `pgxpool` is a documented Phase 11 seam in `lagoon/connection.go`, not created here. |
+| 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) | ✓ VERIFIED | `surf.compile` mounts `GET `+path on `http.NewServeMux` wrapped `recoverJSON(cors(...))`. `wrap` order: locale → named (`jwt.auth`, `inv.must-change-password`) → org slot → no-op rate limit → constraints → handler. Missing names fail Assemble with plugin ID + name. Typed params: `surf.IntParam` + `Where`/`WhereIn` compiled at registration; `examples/hello` `/items/{id}` 404s malformed and unknown IDs. This session: `go test ./surf ./examples/hello -count=1` ok (`TestPipelineOrderRecoverCORSLocaleAuthPasswordOrgRateHandler`, `TestTypedIDRouteReturns404`). |
+| 3 | A JWT-guarded `GET /_fonoteka/api/v1/genres` route returns a real `Genre` row read from Postgres | ✓ VERIFIED | `golem15.user` registers `jwt.auth` (`bouncer.Middleware`, HS256 pinned, `exp`+`sub`, persisted user). `golem15.fonoteka` `Requires()` `golem15.user` and mounts the route. Handler `Lookup[*gorm.DB]`, resolves active collection, left-joins tenant-scoped `COUNT(*)`. `TestGenreListBehindJWT` and `TestGenreCountsScopedToActiveCollection` hit real rows. Seed migration inserts 15 canonical genres. `TestParityCorpus/GET___fonoteka_api_v1_genres_jwt` PASS this session. |
+| 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 | ✓ VERIFIED | Fixture `parity/fixtures/routes/get_genres_jwt.yaml` last commits are Phase 2 (`8b5bd23`, `66ed0bb`) — unmodified in this phase. `newTarget` → `app.Handler` over TestMain SQL pool. `seedHooks["genres"]` mints test-only JWT + colliding IDs. `tide.ReplayFlow` against httptest. Coverage line this session: `recorded 154/154 passing 1 failing 0 unrecorded 0 pending 153`. `check_corpus.go --require-recorded --require-clients --check-secrets` printed `recorded 154/154`. Pending routes load fixtures only and never increment `Passing`. |
+
+**Score:** 4/4 truths verified
+
+Supporting plan truths (D-01…D-20, JWT matrix, seven-stage pipeline, isolated rollback, honest 1-of-154 corpus, security review `threats_open: 0`) all hold in code; they are not extra score rows.

+
+| Artifact | Data | Source | Produces real data | Status |

+## Requirements Coverage
+
+PLAN frontmatter IDs: DATA-01, DATA-02, HTTP-01, HTTP-02, QA-04 (union of 03-01…03-04). REQUIREMENTS.md maps the same five to Phase 3. No Phase 3 orphans. Every ID is accounted for.
+
+| Requirement | Source Plan | Description | Status | Evidence |
+|-------------|-------------|-------------|--------|----------|
+| DATA-01 | 01, 02, 04 | GORM on Postgres through one shared `*sql.DB` (pgx stdlib); River listener pool reserved | ✓ SATISFIED | Shared pool proven (`TestSharedSQLPoolUsedByGORMAndClosed`). Separate `pgxpool` for River LISTEN/NOTIFY is an explicit Phase 11 seam (`lagoon/connection.go`, CONTEXT deferred list). Phase 3 success criterion does not require creating that pool. |
+| DATA-02 | 01, 03, 04 | Per-plugin gormigrate up/down, dependency order, per-plugin version tracking; AutoMigrate never the schema source | ✓ SATISFIED | User then Fonoteka history tables; `RollbackLast` isolates Fonoteka; source scan + tests forbid `AutoMigrate` |
+| HTTP-01 | 01, 03, 04 | Plugins register route groups on ServeMux with typed params and regex constraints; unknown and malformed ids both 404 | ✓ SATISFIED | Fonoteka group `GET /_fonoteka/api/v1/genres`. Typed/constraint API exercised by `examples/hello` and `TestTypedIDRouteReturns404` (genres has no path param) |
+| HTTP-02 | 01, 02, 03, 04 | Named middleware referenced by other plugins; pipeline recover, CORS, locale, auth, must-change-password, org, rate limit, handler | ✓ VERIFIED | `jwt.auth` owned by user, `inv.must-change-password` owned by fonoteka; `TestPipelineOrderRecoverCORSLocaleAuthPasswordOrgRateHandler`; CORS preflight bypasses named auth |
+| QA-04 | 01–04 | First vertical slice `GET /_fonoteka/api/v1/genres` passes the parity diff end to end before further kernel abstraction | ✓ SATISFIED | This session: `recorded 154/154 passing 1 failing 0 unrecorded 0 pending 153`. Pending never counts as passing (`TestParityContract`) |
+
+**Coverage:** 5/5 requirements satisfied
+
+### Decision Coverage
+
+All trackable CONTEXT.md decisions are honored by shipped artifacts. `gsd-sdk query check.decision-coverage-verify`: **20/20 honored**, `not_honored: []`. Handler fidelity D-01–D-06, JWT D-07–D-11, pipeline/routing D-12–D-15, migrations/seed/parity D-16–D-20.
+
+## Behavioral Verification
+
+| Check | Result | Detail |
+|-------|--------|--------|
+| Root `go vet ./... && go test ./...` | ✓ | All packages ok (this session; cached packages plus forced `lagoon`/`bouncer`/`surf`/`pact`/`examples/hello`) |
+| `go test ./lagoon ./bouncer ./surf ./pact ./examples/hello -count=1` | ✓ | lagoon 7.940s (testcontainers); others <3s |
+| App `go vet ./... && go test ./... -count=1` | ✓ | `ok git.golem15.com/golem15/fonoteka/parity` 8.065s |
+| `TestParityCorpus$` | ✓ | `recorded 154/154 passing 1 failing 0 unrecorded 0 pending 153`; `GET /_fonoteka/api/v1/genres jwt` PASS 0.09s |
+| `check_corpus.go --require-recorded --require-clients --check-secrets` | ✓ | `recorded 154/154` |
+| Focused genre/security/migrate tests | ✓ | Included in app `go test ./...` this session |
+| Full `scripts/check-phase3.sh` (includes `-race`) | ℹ not re-run | VALIDATION.md 2026-09-17: ~21s after warmup, `phase3 check passed`. Spot-checks above confirm the same vet/test/corpus/parity path. Race was not re-executed this session. |
+
+## Anti-Patterns Found
+
+No `TODO` / `FIXME` / `XXX` / `TBD` / `HACK` / `coming soon` / `not implemented` in `lagoon`, `surf`, `bouncer`, fonoteka plugins, or `app`. No `AutoMigrate` in production or plugin sources.
+
+| File | Line | Pattern | Severity | Impact |
+|------|------|---------|----------|--------|
+| `surf/serve.go` | ~49 | `http.Server` timeouts left at zero | ⚠️ Warning | Advisory WR-01 from `03-REVIEW.md`. Slowloris hold-open on production `serve`. Does not affect httptest parity path or must-haves. Phase 6 owns HTTP hardening depth; timeouts are serve-command hardening. |
+| `surf/router.go` | 290–300 | `recoverJSON` may append a 500 body after headers committed | ⚠️ Warning | Advisory WR-02. Panic-after-write is untested; genre handler does not panic after write on the passing path. |
+| `cmd/summer/runtime.go` | 15–25 | `summer serve` delegate has no `--addr` flag | ⚠️ Warning | Advisory WR-03. Operators use `./bin/fonoteka serve` or default `:8080`. Not a slice blocker. |
+| `../fonoteka.go/main.go` vs `app/app.go` | 31–37 / 31–43 | Production `Activate` before DB publish; tests Publish then Activate | ⚠️ Warning | Advisory WR-04. Current `Boot` only checks JWT secret, so both paths work. Later plugins that `Lookup[*gorm.DB]()` in `Boot` need this aligned (Phase 5/7). |
+| `../fonoteka.go/parity/synthetic_test.go` | 110 | `t.Skip` under `-short` | ℹ️ Info | Phase 2 fast loop; TestMain still fails closed without Docker when not `-short`. Phase 3 gate runs without `-short`. |
+| `lagoon/postgres_test.go` | 94 | `t.Skip` under `-short` | ℹ️ Info | Same fast-loop pattern for framework ICU Postgres. |
+
+**Anti-patterns:** 6 found (0 blockers, 4 warnings, 2 info)
+
+Code-review advisories WR-05…WR-07 (JWT lookup errors mapped to 401 vs PHP 500; typed-param 404 HTML page; similar) likewise do not fail the genres goal. Security review closed the JWT/tenant threats the slice owns.
+
+## Test Quality Audit
+
+| Test File | Linked Req | Active | Skipped | Circular | Assertion Level | Verdict |
+|-----------|-----------|--------|---------|----------|----------------|---------|
+| `lagoon/connection_test.go` | DATA-01 | yes | `-short` on container helper | no | Behavioral (shared `*sql.DB` identity, ICU fail) | ✓ |
+| `lagoon/migrations_test.go` | DATA-02 | yes | no | no | Behavioral (two-plugin isolation, no AutoMigrate) | ✓ |
+| `bouncer/jwt_test.go` | HTTP-02 | yes | no | no | Value (PHP 401 strings) + Behavioral (alg:none, leak) | ✓ |
+| `surf/middleware_test.go` | HTTP-02 | yes | no | no | Behavioral (order, missing name, unauthenticated) | ✓ |
+| `surf/params_test.go` / `examples/hello/hello_test.go` | HTTP-01 | yes | no | no | Behavioral (malformed+unknown 404) | ✓ |
+| `../fonoteka.go/parity/genre_integration_test.go` | QA-04, D-01–D-06 | yes | no | no | Value (counts, 422 body, order) | ✓ |
+| `../fonoteka.go/parity/genre_security_test.go` | HTTP-02, QA-04 | yes | no | no | Behavioral (401/423/CORS/tenant) | ✓ |
+| `../fonoteka.go/parity/parity_test.go` | QA-04 | yes | no on ported path | no | Value (PHP fixture byte diff) | ✓ |
+| `../fonoteka.go/parity/parity_contract_test.go` | QA-04 | yes | no | no | Value (154/1/153; pending≠pass; mutation fails) | ✓ |
+| `../fonoteka.go/parity/migrate_test.go` | DATA-02 | yes | no | no | Behavioral (15 seeds, rollback isolation) | ✓ |
+
+**Disabled tests on requirements:** 0 blockers (`-short` skips are the documented fast loop, not the sign-off path).
+**Circular patterns detected:** 0. Expected genre JSON is the Phase 2 PHP recording (`get_genres_jwt.yaml`). The `genres` seed hook prepares Postgres + a test JWT so the Go handler can match that external oracle; it does not write the expected fixture from the SUT.
+**Insufficient assertions:** 0. Ported replay is value-level (`tide.ReplayFlow` body/status). Pending rows only load fixtures (honest: no Go handler).
+**Provenance:** VALID — expected body from the live PHP backend (Phase 2). Colliding `{{id:*}}` placeholders are restored from CanonicalGenres seed order (D-20), not from Go response capture.
+
+## Human Verification Required
+
+N/A — Infrastructure/API foundation phase with no user-facing product UI. Acceptance is Postgres + JWT-guarded HTTP + the Phase 2 parity harness. VALIDATION.md's production-DB locale checklist is documented in `../fonoteka.go/README.md` and enforced by `CheckLocale` in Open/Use (wrong locale fails boot); testcontainers create the same ICU `pl-PL` database.
+
+## Gaps Summary
+
+**No gaps found.** Phase goal achieved. All four ROADMAP success criteria hold in the codebase and were exercised this session (root/app vet/test, live `TestParityCorpus` one-of-154 pass, corpus audit). Advisory code-review warnings do not break must-haves.
+
+DATA-01's River listener pool remains a Phase 11 seam by design (CONTEXT deferred; ROADMAP Phase 11 SC1). Not a Phase 3 gap.
+
+## Recommended Fix Plans
+
+None — status is `passed`.
+
+## Verification Metadata
+
+**Verification approach:** Goal-backward from ROADMAP success criteria
+**Must-haves source:** ROADMAP.md success criteria (override PLAN.md frontmatter)
+**Automated checks:** 20 artifacts passed, 11 key links passed (manual; gsd-sdk filename-grep false negatives excluded), 4/4 truths, 5/5 requirements
+**Human checks required:** 0
+**Total verification time:** ~12 min
