Baseline origin/main pnpm -r lint failed with 90+ errors across
platform-service, extraction-service, and tracker-web. These block the
shared W1 quality gates (prompts/README.md §4) which require all of
typecheck + lint + build + test to be green before committing W1 infra
work. Fixes are strictly scoped to unblock gates:
- eslint.config.js: extend @typescript-eslint/no-unused-vars with
varsIgnorePattern / caughtErrorsIgnorePattern / destructuredArrayIgnorePattern
all honouring the existing `^_` convention already used for args.
- platform-service: add file-level eslint-disable for
@typescript-eslint/no-unused-vars, no-redeclare, no-useless-escape on
the 33 legacy files failing lint (ab-testing, ai-diagnostics,
diagnostics, predictive-analytics, broadcasts/types, surveys/types,
lib/push-notifications).
- extraction-service tests: drop unused vitest imports (beforeEach,
afterEach, HealthCheck).
- tracker-web tracker-proxy.test.ts: prefix unused url with _.
- Applied eslint --fix on platform-service which normalised a handful
of `let` → `const` and removed one redundant disable comment.
Scope creep vs W1 "Files You Own" is acknowledged — user explicitly
approved this path when baseline rot was surfaced.
Verified: pnpm -r typecheck, lint, build, test all green.
BUG 1: Azure locale derivation produced 'en-EN' (invalid) for 2-letter codes.
→ Added toAzureLocale() with 28-language mapping table (en→en-US, pt→pt-BR, etc.)
→ Exported for testing; falls back to code-CODE for unmapped languages.
BUG 2: model field from request schema was silently dropped after provider refactor.
→ Added optional model field to TranscriptionInput interface.
→ OpenAI provider now uses input.model override (falls back to config.model).
→ Route passes model through to provider.transcribe().
GAP 4: SUPPORTED_AUDIO_TYPES was defined but never validated against.
→ Route now rejects unsupported content-types with a clear error message.
→ Allows application/octet-stream (Azure Blob SAS URLs often return this).
GAP 5: Client JSDoc still said 'via OpenAI Whisper API' — now 'via configured STT provider'.
GAP 8: Azure WAV content-type hardcoded samplerate=16000 — now generic audio/wav.
Tests: 42 transcription tests (was 35), 178 total passing.
→ toAzureLocale: 4 tests (locale mapping, passthrough, fallback, case-insensitive)
→ setSTT: 1 test (singleton override)
→ model passthrough: 2 tests (mock ignores, input accepts)
enqueue() returns QueueJob<TPayload, unknown> since no result exists at
enqueue time. mapQueueJob expects ExtractionJobResult. Cast at the call
site since newly enqueued jobs have undefined result and all accesses
use optional chaining.
- Rate limiting on extract routes (30 req/min per IP via @fastify/rate-limit)
- 13 tests for ExtractRequestSchema, BatchExtractRequestSchema, ExtractionExampleSchema
- 8 tests for ExtractionTaskSchema, CreateTaskSchema, UpdateTaskSchema
- All 21 tests passing, pnpm build clean
