Tasks: enterprise-gaming-r3f-npc

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/gameplay/r3f-npc/ (@suaveplan/r3f-npc, 0.1.0, sideEffects: false)

Phase 2 — Types + error codes

• src/types/common.ts + common.md
• src/error-codes.ts

Phase 3 — Components

• NpcMesh — composes r3f-character with NpcRegistry state
• BehaviorTreeDebug — floating tree panel with node status colors
• NpcNameplate — billboarded name + health bar + status icon
• DialogueTrigger — proximity interaction prompt wired to @suaveplan/dialogue
• NpcMarker — minimap dot with icon/color
• Tests + Storybook stories for each

Phase 4 — Integration tests

• tests/integration.test.ts — NPC state → mesh, dialogue trigger proximity

Phase 5 — Pre-publish gate

• bunx turbo lint typecheck test --filter=@suaveplan/r3f-npc green
• 100% coverage
• Publish: bun scripts/publish.ts --package @suaveplan/r3f-npc
