+# OpenSpec Change: enterprise-gaming-r3f-controller
+
+- **Change ID**: enterprise-gaming-r3f-controller
+- **Package**: `@suaveplan/r3f-controller`
+- **Category**: gaming/character
+- **Target path**: `gaming/character/r3f-controller`
+- **Status**: PROPOSED
+- **Date**: 2026-04-24
+- **Reference spec**: `/mnt/s/web/suaveplan/enterprise/r3f-controller.md`
+
+---
+
+## Summary
+
+Deliver `@suaveplan/r3f-controller` on the genesis branch from scratch at enterprise quality. The package provides an input controller for 3D scenes in React Three Fiber. It bridges `@suaveplan/controller`'s `ControllerManager` to Three.js camera and character movement: a `CameraController` listens to mouse/gamepad look-axes and applies yaw/pitch to a camera rig; a `MovementController` maps WASD/joystick to a velocity vector in camera-relative space. A `ControllerScene` component wraps both and exposes `useR3FController()`. Genesis adds structured errors and 100% coverage.
+
+---
+
+## Available workspace deps
+
+`@suaveplan/error`, `@suaveplan/controller`, `@suaveplan/react-controller`, react, `@react-three/fiber`, `@react-three/drei`, three.
+
+---
+
+## Public API surface
+
+```ts
+function ControllerScene(props: ControllerSceneProps): JSX.Element
+// manager, mode: 'fps' | 'third-person' | 'orbit'
+
+function useR3FController(): R3FControllerState
+// moveVelocity: Vec3, lookEuler: Euler, isAiming: boolean
+```

+# Tasks: enterprise-gaming-r3f-controller
+
+## 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 + types
+
+## Phase 2 — Camera controller
+
+- [ ] Yaw/pitch from look axes, FPS/third-person/orbit modes
+- [ ] Tests + docs
+
+## Phase 3 — Movement controller
+
+- [ ] Camera-relative velocity from WASD/joystick
+- [ ] Tests + docs
+
+## Phase 4 — `useR3FController` hook
+
+## Phase 5 — `ControllerScene` component + story
+
+## Phase 6 — Pre-publish gate
+
+- [ ] `bunx turbo lint typecheck test --filter=@suaveplan/r3f-controller` green
+- [ ] 100% coverage
+- [ ] Publish: `bun scripts/publish.ts --package @suaveplan/r3f-controller`
