+# OpenSpec Change: enterprise-gaming-r3f-environment
+
+- **Change ID**: enterprise-gaming-r3f-environment
+- **Package**: `@suaveplan/r3f-environment`
+- **Category**: gaming/scene
+- **Target path**: `gaming/scene/r3f-environment`
+- **Status**: PROPOSED
+- **Date**: 2026-04-24
+- **Reference spec**: `/mnt/s/web/suaveplan/enterprise/r3f-environment.md`
+
+---
+
+## Summary
+
+Deliver `@suaveplan/r3f-environment` on the genesis branch from scratch at enterprise quality. The package provides skybox, HDR environment maps, and lighting presets for React Three Fiber. An `Environment` component accepts a preset name or HDR URL and sets up `@react-three/drei`'s `Environment` with PMREM generation; a procedural `Sky` component renders sun disc and atmosphere scattering; a `LightingPreset` component configures ambient + directional lights from `@suaveplan/day-night`'s `LightKeyframe`. Genesis adds structured errors, and 100% coverage.
+

+
+## Available workspace deps
+
+`@suaveplan/error`, `@suaveplan/day-night`, react, `@react-three/fiber`, `@react-three/drei`, three.

+# Tasks: enterprise-gaming-r3f-environment
+
+## 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
+
+- [ ] Create `gaming/scene/r3f-environment/` + `src/types/common.ts`
+
+## Phase 2 — Presets
+
+- [ ] Named presets: day, dusk, night, overcast, sunrise, sunset
+
+## Phase 3 — Components + stories
+
+- [ ] `Sky` — drei Sky wrapper with configurable atmosphere params
+- [ ] `Environment` — HDRI/preset wrapper
+- [ ] `LightingPreset` — ambient + directional from LightKeyframe
+
+## Phase 4 — `useEnvironment` hook + docs
+
+## Phase 5 — Pre-publish gate
+
+- [ ] `bunx turbo lint typecheck test --filter=@suaveplan/r3f-environment` green
+- [ ] 100% coverage
+- [ ] Publish: `bun scripts/publish.ts --package @suaveplan/r3f-environment`
