# Phase 3 — Validation Strategy

## Test Infrastructure

| Property | Value |
|---|---|
| Framework | Go 1.27 `testing`, `httptest`; existing `../fonoteka.go/parity` testcontainers Postgres suite; framework `lagoon` tests now share the same STACK-named testcontainers modules |
| Config | Root `go.mod` plus app `../fonoteka.go/go.mod`; existing `go.work` only covers the framework and hello example |
| Quick run | `go vet ./... && go test ./...` in each of `summercms.go` and `../fonoteka.go` |
| Full suite | `bash scripts/check-phase3.sh` — root and app vet/test/race, focused real genres parity, genre security/tenant tests, corpus audit, Phase 2 Go/CLI harness regression (TestParitySynthetic + CLI record/replay smoke) |
| Repeatable gate | `scripts/check-phase3.sh`; Phase 2 PHP self-replay remains `scripts/check-phase2.sh --fresh-php` |
| Measured runtime | Successful `check-phase3.sh` run: **~21s** after cache warmup (2026-09-17). Focused `TestParityCorpus$` 5.115s; focused genre security 5.003s; `TestParitySynthetic` 4.951s; CLI smoke recorded + `replay matched`. |

## Sampling Rate

- After every implementation task commit: root `go vet ./... && go test ./...`; after app files exist, run the same commands in `../fonoteka.go`.
- After each plan wave: run the focused Postgres route/genre test and the ported parity subtest in the app, plus the quick checks.
- Before Phase 3 verification: `bash scripts/check-phase3.sh`. Docker unavailable is a failed gate; `testing.Short` remains a fast local option only.

## Per-Task Verification Map

The user confirmed four plans on 2026-09-17. Every task has an automated `<verify>` command and an observable acceptance criterion. Rows below are filled from plan summaries plus the 03-04 gate.

| Task ID | Wave | Requirement | Threat | Automated evidence | Status |
|---|---:|---|---|---|---|
| 03-01-01 | 1 | DATA-01, DATA-02 | T-03-01, T-03-SC | Root/app vet/test; Postgres 16 ICU migration smoke, 15 seeds, separate history | Pass — 03-01 SUMMARY (`d0d8450` / `55f110e`) |
| 03-01-02 | 1 | HTTP-01, HTTP-02, QA-04 | T-03-02, T-03-03 | Root/app vet/test; persisted-user JWT request reaches real genre row | Pass — 03-01 SUMMARY (`4ee4c4a` / `d7915a8`); 401/423 never reach handler |
| 03-02-01 | 2 | QA-04 | T-03-04 | Root/app vet/test; focused TestGenre nonzero/foreign/editor counts | Pass — 03-02 SUMMARY (`fc7d581`) |
| 03-02-02 | 2 | QA-04 | T-03-05 | Root/app vet/test; focused TestGenre `non_empty`, 422, 15-name order | Pass — 03-02 SUMMARY (`56be82f` / `f5adabc`) |
| 03-03-01 | 3 | DATA-02, HTTP-01 | T-03-01, T-03-07 | Root/app vet/test; rollback isolation and hello typed route | Pass — 03-03 SUMMARY (`8e3bf26` / `91e3df4`) |
| 03-03-02 | 3 | QA-04 | T-03-06 | Root/app vet/test; TestParityCorpus one real pass and 153 pending | Pass — 03-03 SUMMARY (`0cc1a4d`); fixture unmodified |
| 03-04-01 | 4 | DATA-01, DATA-02, HTTP-01, HTTP-02 | T-03-01 to T-03-03 | Root vet/test/race and app vet/test; adversarial auth/routing tests | Pass — `92255a46ed039f605231ad71eed243436c4a1fbc`; re-run green in 03-04 gate |
| 03-04-02 | 4 | QA-04, HTTP-02 | T-03-04 to T-03-07 | `bash scripts/check-phase3.sh`; app test/race, Go/CLI harness regression, security review | Pass — 2026-09-17, `phase3 check passed`; app `c6615683cbd5bb10cc141bee69f1938c46450ffe`; script `c2dfa7b62f3ba993dbfc50313f437c367770b3cb`; gate follow-up `fda61f0c1519e0756e966a64b868a8f92085fcb7` |

| Capability | Requirement | Threat | Test and evidence |
|---|---|---|---|
| Shared pgx/GORM connection and plugin migrations | DATA-01, DATA-02 | T-03-01 schema drift | `TestWrongICULocaleFailsOpen`, `TestTwoPluginMigrationSetsIsolated`, `TestNoAutoMigrate`, app `TestMigrateSeedsCanonicalGenres`, `TestRollbackLastIsolatesFonoteka`. ICU `pl-PL` required before GORM. Two plugin histories survive independent up/down/rollback. No `AutoMigrate`. |
| Named route and middleware pipeline | HTTP-01, HTTP-02 | T-03-02 auth bypass | `TestAssembleMissingMiddlewareFailsBoot`, `TestUnauthenticatedNamedGuardDoesNotReachHandler`, `TestPipelineOrderRecoverCORSLocaleAuthPasswordOrgRateHandler`, `TestCORSPreflightBypassesNamedAuth`, `TestTypedIDRouteReturns404`. Missing names fail boot with plugin+name; unauthenticated GET never sets handler `Cache-Control`. |
| JWT guard | HTTP-02, QA-04 | T-03-03 token forgery | `TestVerifyRejectsBadTokens`, `TestVerifyRejectsAlgNoneEmptySecretAndAbsentExp`, `TestVerifyAndMiddlewareOmitTokenAndSecret`, app `TestGenreSecurityBoundaries`, `TestEmptyJWTSecretFailsBoot`. HS256 pinned; empty secret fails Boot; 401 bodies omit token/secret. |
| Active collection and genre aggregate | QA-04 | T-03-04 cross-tenant data leak | `TestGenreCountsScopedToActiveCollection`, `TestGenreSecurityBoundaries/alice-counts-ignore-foreign`, `/bob-counts-ignore-alice`. Foreign albums stay at count 0. Invalid stored context falls back to lowest-ID accessible collection. |
| Polish order | QA-04 | T-03-05 sort drift | `TestOrderClauseAllowList`; integration 15-name order under ICU `pl-PL`; `TestGenreQueryFailsOnWrongLocale`. No COLLATE. Invalid `non_empty` returns PHP 422 envelope. |
| Recorded parity | QA-04 | T-03-06 false green | Unmodified `fixtures/routes/get_genres_jwt.yaml`; `TestParityCorpus` 154 recorded, 1 passing, 153 pending, 0 failing, 0 unrecorded; `TestParityContract/honest-counts` and `ported-mutated-response`. |

## Wave 0 Requirements

- [x] Existing `../fonoteka.go/parity/TestMain` starts a Postgres container and the recorded fixture exists. Plan 01 added real app boot and a focused route smoke test before Plan 03 moved `newTarget`.
- [x] Test helper for applying both plugin migration sets and seeding Alice's active collection lives in the app test package (`genres_seed_test.go`), not `tide`.
- [x] No additional test framework or watch mode was required. testcontainers-go v0.44.0 is the STACK-named dependency used by framework `lagoon` isolation tests.

## Manual-Only Verifications

| Behavior | Requirement | Why manual | Test instructions | Result |
|---|---|---|---|---|
| Database provisioning | QA-04 | Production Postgres lies outside the test suite | Use a fresh database created with `TEMPLATE template0`, `LOCALE_PROVIDER icu`, `ICU_LOCALE 'pl-PL'`, and UTF8 encoding; run the startup locale check before migrations. | **Documented in `../fonoteka.go/README.md`.** Testcontainers databases are created the same way in `lagoon/postgres_test.go` and app `TestMain`. Wrong-locale Open fails. |

## Phase 3 gate evidence (03-04-02)

Commands (no credentials):

```bash
go vet ./... && go test ./... && go test -race ./...          # summercms.go
(cd ../fonoteka.go && go vet ./... && go test ./... && go test -race ./...)
(cd ../fonoteka.go && go test ./parity -count=1 -run 'TestParityCorpus$')
(cd ../fonoteka.go && go test ./parity -count=1 -run 'TestGenreSecurityBoundaries|TestGenreCountsScopedToActiveCollection|TestGenreQueryFailsOnWrongLocale')
(cd ../fonoteka.go && go run ./parity/check_corpus.go \
  --manifest ../fonoteka.go/parity/manifest.yaml \
  --routes /media/nvme/dev/golem15/fonoteka/plugins/golem15/fonoteka/routes.php \
  --require-recorded --require-clients --check-secrets)
(cd ../fonoteka.go && go test ./parity -run TestParitySynthetic -count=1)
bash scripts/check-phase3.sh
```

Observed (2026-09-17, `bash scripts/check-phase3.sh` exit 0):

- Docker present; missing Docker is an explicit refuse, not a skip.
- Root vet/test/race: all packages `ok` (cached after first run).
- App vet/test/race: `ok git.golem15.com/golem15/fonoteka/parity`.
- Focused genres parity (`TestParityCorpus$`): `ok` in 5.115s — one real ported pass.
- Focused genre security/tenant: `ok` in 5.003s.
- Corpus audit: `recorded 154/154`.
- `TestParitySynthetic`: `ok` in 4.951s.
- CLI smoke: `parity:record` wrote a loopback fixture; `parity:replay` printed `replay matched`.
- Script printed `phase3 check passed`.

Corpus honesty (app `TestParityContract` / `TestParityCorpus`): **154 recorded, 1 passing, 153 pending, 0 failing, 0 unrecorded**. A deliberate `album_count` mutation fails `ReplayFlow`. The recorded PHP fixture is unchanged (`Bearer {{jwt:alice}}`, `"album_count":0`).

PHP `--fresh-php` (Phase 2 sign-off, not this gate): as of 2026-09-17 `scripts/check-phase2.sh --fresh-php` reports **150/154** on four wishlist `album_count` routes (expected 1, live 2). Phase 3 did not edit PHP, tide, or those fixtures. The Phase 3 script therefore re-runs the Phase 2 Go/CLI harness pieces and leaves PHP self-replay at `check-phase2.sh`.

Prior implementation commits (03-01 through 03-03, plus 03-04 Task 1) ran `go vet ./...` and `go test ./...` green in their summaries.

Security review: `03-SECURITY-REVIEW.md` maps T-03-01 through T-03-07 and T-03-SC to passing tests; `threats_open: 0`; no open high-severity JWT or cross-tenant issue.

## Validation Sign-Off

- [x] Plan IDs and per-task commands filled after plan-count checkpoint.
- [x] Every task has automated feedback; no three consecutive tasks without it.
- [x] Security threat model appears in each plan and the final plan tests its high severity mitigations.
- [x] Root and app quick checks, race checks, Postgres integration, and recorded parity are green.
- [x] Mark `nyquist_compliant: true` only after implementation evidence exists.

**Approval:** Phase 3 gate evidence recorded 2026-09-17. `nyquist_compliant: true`.
