# Tasks: enterprise-gaming-bone-mapping

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

## Phase 2 — Error codes & constants

- [ ] `src/error-codes.ts` + `src/constants/index.ts` — canonical human bone list, keyword weights

## Phase 3 — Types

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

## Phase 4 — Quaternion math utils

- [ ] `src/utils/quat-math.ts` — multiply, inverse, slerp, toMatrix, fromMatrix
- [ ] Tests + docs

## Phase 5 — Skeleton detection

- [ ] `src/core/detect/detect.ts` — fuzzy name matching against humanoid canonical list
- [ ] Tests + docs

## Phase 6 — Bone matching

- [ ] `src/core/match/match.ts` — Levenshtein + anatomical keyword boost, `minConfidence` filter
- [ ] Tests + docs

## Phase 7 — Retargeting

- [ ] `src/core/retarget/retarget.ts` — `buildRetargetMatrix`, `retargetPose`
- [ ] Tests + docs

## Phase 8 — Property tests

- [ ] `tests/property.test.ts` — retarget round-trip (source == target skeleton → identity), match symmetry

## Phase 9 — Pre-publish gate

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