# Tasks: enterprise-gaming-api-plugin-matchmaking

## 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.

## Phase 1 — Scaffold

- [ ] Create `gaming/server/api-plugin-matchmaking/` (`@suaveplan/api-plugin-matchmaking`, `0.1.0`, `sideEffects: false`)
- [ ] `tsconfig.json`, `vitest.config.ts`

## Phase 2 — Error codes + types

- [ ] `src/error-codes.ts` + `src/types/common.ts` + `common.md`

## Phase 3 — Matchmaking queue

- [ ] `src/core/matchmaking-queue/matchmaking-queue.ts` — sorted enqueue, time-expanding gap, team builder, events, OTel
- [ ] Tests (balanced teams, expanding gap, already-queued guard)
- [ ] Docs

## Phase 4 — Queue routes

- [ ] `src/routes/queue.ts` — enqueue/dequeue/status/tick/stats
- [ ] `src/routes/queue.md`

## Phase 5 — Plugin factory

- [ ] `src/plugin.ts` — `matchmakingPlugin()` factory
- [ ] `src/plugin.md`

## Phase 6 — Integration tests

- [ ] `tests/integration.test.ts` — enqueue players → POST /queue/tick → verify match_found

## Phase 7 — Pre-publish gate

- [ ] `bunx turbo lint typecheck test --filter=@suaveplan/api-plugin-matchmaking` green
- [ ] 100% coverage
- [ ] Publish: `bun scripts/publish.ts --package @suaveplan/api-plugin-matchmaking`
