# Tasks: enterprise-gaming-chat

## 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.

- [ ] `src/error-codes.ts` + `src/constants/index.ts` — `DEFAULT_HISTORY_SIZE`, `DEFAULT_RATE_LIMIT`

## Phase 3 — Types

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

## Phase 4 — Rate limiter utility

- [ ] `src/utils/rate-limiter.ts` — sliding-window per-player counter

## Phase 5 — Profanity filter

- [ ] `src/utils/profanity-filter.ts` — blocklist trie, mask/block mode, whole-word detection

## Phase 6 — Chat channel

- [ ] `src/core/chat-channel/chat-channel.ts` — history ring buffer, subscribe/unsubscribe
- [ ] Tests + docs

## Phase 7 — Chat manager

- [ ] `src/core/chat-manager/chat-manager.ts` — sendMessage/whisper/mute/unmute/tick, rate + mute checks, OTel
- [ ] Tests + docs

## Phase 8 — Integration tests

- [ ] `tests/integration.test.ts` — channel message flow, rate limit, mute expiry, whisper

## Phase 9 — Pre-publish gate

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