From a63f1e2c730fce491988279f5627497cf43cc1ff Mon Sep 17 00:00:00 2001 From: Claude Date: Thu, 11 Jun 2026 21:04:24 +0000 Subject: [PATCH 1/3] =?UTF-8?q?test:=20cross-boundary=20Phase=201=20contra?= =?UTF-8?q?ct=20gate=20=E2=80=94=20kill=20the=20silent-field-drop=20class?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The Phase 1 contract lives in three hand-maintained reconstructions (analyze.py output, _build_phase1 in server_phase1.py, parsePhase1Result in backendPhase1Client.ts) plus two declarative mirrors (JSON_SCHEMA.md, types/measurement.ts), and nothing executable defended the boundary — the 2026-05-30 full review traced the dropped reverbDetail/vocalDetail citation fields to exactly this gap (CLAUDE.md tripwires #3/#4). This makes the boundary executable end to end: Backend (tests/test_phase1_golden.py): - The golden snapshot now records a recursive structure-only `keyTree` (dicts recurse; lists of objects record the union of element keys; scalars reduce to type categories; nested null<->scalar flips are tolerated as runner noise, container-shape changes always bite). Regenerated golden arms it (+426 lines, purely additive). - New keytree gate compares every nested key the analyzer emits against the committed tree; goldens predating keyTree skip visibly, not silently. - New superset gate pins that _build_phase1 forwards every golden top-level key — the third reconstruction layer, previously unguarded. - KeyTreeMetaTests prove the comparator bites (and doesn't over-bite). Frontend (apps/ui): - tests/fixtures/phase1FullPayload.ts: the inline validPayload promoted to a shared, enriched envelope-shaped fixture covering all 66 golden top-level keys (9 were missing) with realistic nested values. - tests/services/phase1ContractParity.test.ts: five gates driven by the backend golden — A1 every golden key exists in the fixture; A2 reverse (fixture rot on backend deletions); A3 every nested keyTree path exists in the fixture (auto-arms off the golden); B the fixture survives the real parsePhase1Result with every non-null path intact (the silent-drop check); C the canonical run path strips exactly transcriptionDetail and nothing else. Server-side transforms (stereo hoist, spectral *Mean renames, staged strip) are a declared, cited map — an undeclared transform fails the gate. - Fix the live instance the gate caught on first run: parsePhase1Result silently dropped phase1Version (emitted by the server, declared in the type, never forwarded). Gate A3's arming also surfaced stale segmentLoudness/segmentSpectral fixture shapes — corrected to the real analyzer contract. Docs: tripwires #3/#4, JSON_SCHEMA.md, and apps/ui/AGENTS.md now point at the executable gates. Verified: apps/ui `npm run verify` green (756 unit incl. the 6 new gates active with zero skips, 49 smoke); backend test_phase1_golden (27), test_analyze + test_server (374) green in a fresh py3.11 venv; mutation checks observed red-then-green for a parser-side drop (preDelayMs), a fixture-side gap (vocalDetail), and the live phase1Version drop. https://claude.ai/code/session_014eU638tNAHuV3bXDZStuNU --- CLAUDE.md | 4 +- apps/backend/JSON_SCHEMA.md | 2 +- .../tests/fixtures/golden/phase1_default.json | 426 +++++++++++++ apps/backend/tests/test_phase1_golden.py | 324 ++++++++++ apps/ui/AGENTS.md | 1 + apps/ui/src/services/backendPhase1Client.ts | 1 + apps/ui/tests/fixtures/phase1FullPayload.ts | 576 ++++++++++++++++++ .../services/backendPhase1Client.test.ts | 301 +-------- .../services/phase1ContractParity.test.ts | 366 +++++++++++ 9 files changed, 1698 insertions(+), 303 deletions(-) create mode 100644 apps/ui/tests/fixtures/phase1FullPayload.ts create mode 100644 apps/ui/tests/services/phase1ContractParity.test.ts diff --git a/CLAUDE.md b/CLAUDE.md index bfac519d..09e5eb8e 100644 --- a/CLAUDE.md +++ b/CLAUDE.md @@ -400,8 +400,8 @@ Things that look like normal code changes but silently break the contract.

Service-layer tests are pure logic; if you need DOM, it's a Playwright test in `tests/smoke/` instead. 6. **Hard-coding `Path(...)` for artifacts in new code.** Artifact access must go through [artifact_storage.py](apps/backend/artifact_storage.py). Direct paths work in `local` profile and break silently in `hosted`. 7. **Editing `apps/ui/.env` and expecting `dev.sh` to honor it.** `dev.sh` reads `apps/ui/.env` but *overrides* `VITE_API_BASE_URL` for the spawned UI process so stale `.env` files don't break the stack. To point the UI at a non-canonical backend, edit `dev.sh` or run the UI directly with the env var on the command line. diff --git a/apps/backend/JSON_SCHEMA.md b/apps/backend/JSON_SCHEMA.md index b4f4a9ad..1d48af8b 100644 --- a/apps/backend/JSON_SCHEMA.md +++ b/apps/backend/JSON_SCHEMA.md @@ -17,7 +17,7 @@ Top-level keys: `phase1Version`, `bpm`, `bpmConfidence`, `bpmPercival`, `bpmAgreement`, `bpmDoubletime`, `bpmSource`, `bpmRawOriginal`, `key`, `keyConfidence`, `keyProfile`, `tuningFrequency`, `tuningCents`, `timeSignature`, `timeSignatureSource`, `timeSignatureConfidence`, `durationSeconds`, `sampleRate`, `lufsIntegrated`, `lufsRange`, `lufsMomentaryMax`, `lufsShortTermMax`, `lufsCurve`, `truePeak`, `crestFactor`, `dynamicSpread`, `monoCompatible`, `plr`, `dynamicCharacter`, `textureCharacter`, `stereoDetail`, `spectralBalance`, `spectralBalanceTimeSeries`, `spectralDetail`, `stemAnalysis`, `transientDensityDetail`, `saturationDetail`, `snareDetail`, `hihatDetail`, `rhythmDetail`, `melodyDetail`, `transcriptionDetail`, `pitchDetail`, `grooveDetail`, `beatsLoudness`, `rhythmTimeline`, `sidechainDetail`, `reverbDetail`, `vocalDetail`, `acidDetail`, `supersawDetail`, `bassDetail`, `kickDetail`, `genreDetail`, `effectsDetail`, `synthesisCharacter`, `danceability`, `structure`, `arrangementDetail`, `segmentLoudness`, `segmentSpectral`, `segmentStereo`, `segmentKey`, `chordDetail`, `perceptual`, `essentiaFeatures`. -**Shared (fast + full) vs full-only.** Fast-mode output is asserted byte-for-byte against the `EXPECTED_TOP_LEVEL_KEYS` set in [`tests/test_analyze.py`](tests/test_analyze.py).
