+# OpenSpec Change: enterprise-gaming-r3f-shaders
+
+- **Change ID**: enterprise-gaming-r3f-shaders
+- **Package**: `@suaveplan/r3f-shaders`
+- **Category**: gaming/effects
+- **Target path**: `gaming/effects/r3f-shaders`
+- **Status**: PROPOSED
+- **Date**: 2026-04-24
+
+---
+
+## Summary
+
+Deliver `@suaveplan/r3f-shaders` on the genesis branch from scratch at enterprise quality. The package provides a library of custom shader effects and materials for React Three Fiber: hologram, dissolve, outline, rim-light, toon, heat-distortion, and x-ray materials; GLSL utility functions (noise, rotation, gamma correction); a `ShaderMaterial` factory with hot-reload support in dev mode. Each shader is a typed React component that accepts uniform props. Genesis adds structured errors, and 100% coverage.
+

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

+# Tasks: enterprise-gaming-r3f-shaders
+
+## 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 + GLSL utils
+
+## Phase 2 — `createShaderMaterial` factory + tests
+
+## Phase 3 — Materials (each: component + GLSL + test + story)
+
+- [ ] Hologram, Dissolve, Outline, Toon, RimLight
+
+## Phase 4 — Pre-publish gate
+
+- [ ] `bunx turbo lint typecheck test --filter=@suaveplan/r3f-shaders` green
+- [ ] 100% coverage
+- [ ] Publish: `bun scripts/publish.ts --package @suaveplan/r3f-shaders`
