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
