# Tasks — `@suaveplan/api-router-in-memory`

> Every checkbox MUST reflect work actually done in this change.

## 0. Pre-flight (non-negotiable)

- [ ] 0.1 Confirm clean working tree (`git status` reports nothing) and no in-flight worktrees with uncommitted work (`git worktree list` then `git status` in each)
- [ ] 0.2 If any worktrees exist under `.claude/worktrees/`, account for each one: still-active agent, work-pending-merge, or stale-and-prune. Stale worktrees MUST be removed (`git worktree remove`) before opening a new one — code that has been lost twice on main is the failure mode this guards against.
- [ ] 0.3 Confirm the package set in `MANIFEST.md` matches `find packages -maxdepth 3 -name package.json` count. Drift here means a prior change archived without regenerating the manifest.

## 1. Spec authoring

- [x] 1.1 Read design doc (§13.2, §13.4, §15 Stage 5)
- [x] 1.2 Read `openspec/changes/api-router/` and `openspec/changes/api-conformance-suites/` (this change set)
- [x] 1.3 Read `openspec/AGENTS.md` Sections 13 and 14
- [x] 1.4 Draft `proposal.md`
- [x] 1.5 Draft `specs/api-router-in-memory/spec.md`
- [x] 1.6 Every requirement carries `**Verified by:**`

## 2. Implementation

- [ ] 2.1 Scaffold `packages/api/api-router-in-memory/` (deps: api-router, api-types, error)
- [ ] 2.2 `src/options/in-memory-router-options.ts` — Zod schema
- [ ] 2.3 `src/factory/create-in-memory-router.ts` — direct surface
- [ ] 2.4 `src/fetch-shape/fetch-shape.ts` — `host.fetch(method, path, init?)` entry point
- [ ] 2.5 `src/recording/request-log.ts` — bounded history with `reset()`
- [ ] 2.6 `src/error-codes.ts` — `ROUTER_IN_MEMORY_*` codes via `defineCodes`
- [ ] 2.7 `src/index.ts` — explicit named re-exports
- [ ] 2.8 Register this adapter in `@suaveplan/api-host/testing`'s adapter table (in that package's change — cross-link only here)

## 3. Tests

- [ ] 3.1 `src/factory/create-in-memory-router.test.ts`
- [ ] 3.2 `src/factory/create-in-memory-router.spec-conformance.test.ts` — `runRouterConformance` direct
- [ ] 3.3 `src/fetch-shape/fetch-shape.test.ts`
- [ ] 3.4 `src/recording/request-log.test.ts`
- [ ] 3.5 `tests/integration/integration.test.ts` — via `createTestHost`
- [ ] 3.6 Every `it(...)` carries `{ timeout: 5000 }`

## 4. Documentation

- [ ] 4.1 Sibling `.md` per implementation `.ts`
- [ ] 4.2 README documents the `host.fetch` usage pattern from §13.2 verbatim
- [ ] 4.3 README states: "production-grade in-memory adapter, not a test double"

## 5. Pre-archive verification (5-gate triple)

- [ ] 5.1 `bun run check` — clean
- [ ] 5.2 `bunx turbo lint typecheck test --filter=@suaveplan/api-router-in-memory` — green
- [ ] 5.3 `bunx turbo test:coverage --filter=@suaveplan/api-router-in-memory` — 100/100/100/100
- [ ] 5.4 `bun scripts/openspec-conformance.ts @suaveplan/api-router-in-memory` — exit 0
- [ ] 5.5 `bunx turbo build --filter=@suaveplan/api-router-in-memory` — green

## 6. Pre-archive 7-row checklist

- [ ] 6.1 `expectTypeOf` asserts `host.fetch` matches the design doc's signature
- [ ] 6.2 Zod schema at options boundary
- [ ] 6.3 Every `ROUTER_IN_MEMORY_*` code thrown by at least one production path
- [ ] 6.4 Strict-mode (`trackRequests` on/off) tested both ways
- [ ] 6.5 OTel instruments emitted (same set as `api-router-hono`'s histogram + counter) asserted with in-memory `MeterProvider`
- [ ] 6.6 Route registration dedup tested (duplicate path throws `ROUTER_IN_MEMORY_DUPLICATE_ROUTE`)
- [ ] 6.7 No retroactive tick

## 7. Archive

- [ ] 7.1 Fold into `openspec/specs/api-router-in-memory/spec.md`
- [ ] 7.2 Move to `openspec/archive/<yyyy-mm-dd>-api-router-in-memory/`
- [ ] 7.3 Tick Stage 5 box in umbrella tasks
- [ ] 7.4 Refresh `MANIFEST.md`
