+# Tasks — testing-integration spec authoring + generics hardening
+
+## 1. Spec authoring
+
+- [x] 1.1 Read `openspec/AGENTS.md` Sections 13 and 14
+- [x] 1.2 Draft `proposal.md` (genesis-original; no source mapping section)
+- [x] 1.3 Draft `specs/testing-integration/spec.md` — every requirement carries `**Verified by:**`
+- [x] 1.4 Draft six variant spec files — every requirement carries `**Verified by:**`
+
+## 2. Plumbing
+
+- [x] 2.1 Move `vitest` to `peerDependencies` on `@suaveplan/testing-integration`
+- [x] 2.2 Move `@suaveplan/testing-integration` and `testcontainers` from `dependencies` to `peerDependencies` on all six variants; add to `devDependencies`
+- [x] 2.3 Move `_fixtureRegistry`, `_createIntegrationSetupWithInject`, `_createSkipIfUnavailableWithInject` to `src/internal/` (not exported in `package.json`)
+- [x] 2.4 Public barrel re-exports only the supported surface
+- [x] 2.5 `mailpit` adds `zod` to `dependencies` (catalog:forms)
+
+## 3. Generics
+
+- [x] 3.1 `TestEnvironment<TFixtures extends DefaultFixtureMap = DefaultFixtureMap>` — `setup()` returns precise `configs` shape
+- [x] 3.2 `HealthPoller.poll<TConfig>` — accepts `Pick<ServiceFixture<TConfig>, "name" | "healthCheck">`
+- [x] 3.3 `skipIfUnavailable<TName extends string = string>` — typed-registry friendly
+- [x] 3.4 `expectTypeOf` pins in `test-environment.spec-conformance.test.ts`
+- [x] 3.5 `assertMail` Zod-validated, throws `TestEnvironmentError`
+- [x] 3.6 `GarageS3Fixture.waitForHealth` delegates to `HealthPoller.poll(this)`
+
+## 4. Documentation
+
+- [x] 4.1 New sibling `.md` for every new `internal/*.ts`
+- [x] 4.2 Updated `create-integration-setup.md`, `assert-mail.md`, `garage-s3-fixture.md` to reflect API changes
+
+## 5. Pre-archive verification (5-gate triple, all 7 packages)
+
+- [ ] 5.1 `bun run check` — Biome 0/0/0 across the monorepo
+- [ ] 5.2 `bunx turbo lint typecheck test --filter=@suaveplan/testing-integration{,-*}` green
+- [ ] 5.3 `bunx turbo test:coverage --filter=@suaveplan/testing-integration{,-*}` 100/100/100/100
+- [ ] 5.4 `bun scripts/openspec-conformance.ts @suaveplan/testing-integration{,-*}` exit 0
+- [ ] 5.5 `bunx turbo build --filter=@suaveplan/testing-integration{,-*}` green
+
+## 6. Pre-archive 7-row checklist
+
+- [x] 6.1 Generics threaded; `expectTypeOf` assertions on every literal-type claim
+- [x] 6.2 Zod schemas wired at the assertMail boundary
+- [x] 6.3 `TestEnvironmentError` thrown by every documented error path (`HealthPoller`, `assertMail` non-2xx / timeout / shape mismatch)
+- [x] 6.4 Strict-mode behaviors covered (passthrough mode tests + container mode tests)
+- [x] 6.5 OTel — N/A; testing-infrastructure packages do not register OTel
+- [x] 6.6 Lifecycle dedup — `setup()` re-clears `started` so double-`teardown` is safe; tested
+- [x] 6.7 No retroactive tick — every box reflects work done in this change
+
+## 7. Archive
+
+- [ ] 7.1 Fold spec deltas into `openspec/specs/testing-integration{,-*}/spec.md`
+- [ ] 7.2 Move change folder → `openspec/archive/2026-04-27-testing-integration-spec-and-generics-hardening/`
