# Tasks — testing-spec-conformance

- [x] Tighten `scripts/openspec-conformance.ts` to match change folders by `**Package**:` frontmatter only (drop folder-name token regex). Drop active-change `specs/<cap>/` pull-ins for changes that don't name this package.
- [x] Re-run `bun scripts/openspec-conformance.ts @suaveplan/testing` and confirm req count drops from 226 → 35 → (after Verified-by folding) 0 errors.
- [x] Thread `<TBody = unknown>` through `TestRequest`, `TestResponse`, `RequestBuilderState`, `ResponseBuilderState`, `RequestBuilder`, `ResponseBuilder`. Default preserves `unknown` for zero-config callers.
- [x] Thread `T = unknown` through `MutableFixtureState` (internal but published in dist d.ts).
- [x] Replace `Date.now()` / `performance.now()` fallbacks in `measureTime` and `withObservability` with the injectable `Clock` substrate (`defaultClock` default).
- [x] Add `tests/spec-conformance.spec-conformance.test.ts` covering: generic threading via `expectTypeOf`, package.json `sideEffects: false`, every public surface has a subpath export, module-scope determinism scan, schema modules don't import siblings.
- [x] Add `**Verified by:**` lines under every `### Requirement:` block in `openspec/specs/testing/spec.md`. Citations name real `it(...)` titles.
- [x] Correct stale `packages/universal/testing/` references in the spec to `packages/dev/testing/`.
- [x] Verify `bunx vitest run` is green (295 + 7 new = 302 tests).
- [x] Verify `bunx turbo build --filter=@suaveplan/testing` regenerates dist with the new generics.
- [x] Verify `bun scripts/openspec-conformance.ts @suaveplan/testing` PASS, 0 errors.
- [x] Pre-publish gate: `bunx turbo lint typecheck test --filter=@suaveplan/testing`.
- [x] Coverage gate: `bunx turbo test:coverage --filter=@suaveplan/testing` (Istanbul ≥ 100/100/100/100 per project policy).
- [x] On archive: fold spec deltas into `openspec/specs/testing/spec.md` (already folded inline) and move this folder to `openspec/archive/<yyyy-mm-dd>-testing-spec-conformance/`.
