# Tasks: enterprise-gaming-animation-events

## 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/rigs/animation-events/` (`@suaveplan/animation-events`, `0.1.0`, `sideEffects: false`)
- [ ] `tsconfig.json`, `vitest.config.ts`

## Phase 2 — Error codes & constants

- [ ] `src/error-codes.ts` + `src/constants/index.ts`

## Phase 3 — Types

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

## Phase 4 — Event track

- [ ] `src/core/event-track/event-track.ts` — sorted events, range query, wrap-around
- [ ] Tests + docs

## Phase 5 — Dispatcher

- [ ] `src/core/dispatcher/dispatcher.ts` — normalised time delta dispatch, loop wrap, OTel counter
- [ ] Tests + docs

## Phase 6 — Foot contact detector

- [ ] `src/core/foot-contact/foot-contact.ts` — Y-velocity windowed average, plant position tracking
- [ ] Tests + docs

## Phase 7 — Procedural modifiers

- [ ] `src/modifiers/head-bob/head-bob.ts` — sinusoidal bob driven by movement speed
- [ ] `src/modifiers/breathing/breathing.ts` — chest/spine sway at breathing rate
- [ ] `src/modifiers/aim-offset/aim-offset.ts` — `solveLookAt` additive spine rotation
- [ ] Tests + docs for all three

## Phase 8 — Integration tests

- [ ] `tests/integration.test.ts` — track events dispatched over full animation loop, foot contact + IK plant

## Phase 9 — Pre-publish gate

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