Tasks: enterprise-gaming-r3f-vegetation

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/scene/r3f-vegetation/ (@suaveplan/r3f-vegetation, 0.1.0, sideEffects: false)

Phase 2 — Types + error codes + biome rules

• src/types/common.ts + biome rule schema + types

Phase 3 — Instance placer

• Poisson-disk / random scatter with height/slope filtering from terrain height-sample
• Tests + docs

Phase 4 — Wind shader

• GLSL wind sway vertex shader as TS string constant

Phase 5 — Components + stories

• VegetationLayer — single vegetation type instanced
• Vegetation — all biome layers composed

Phase 6 — Pre-publish gate

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