Verification

• Local code-review fallback: APPROVED WITH UNITY SMOKE GAP. Nakama boundary, LLM safety, deterministic tests, and DTO/HUD scope reviewed locally. Unity compile/Play Mode remains pending because JOY is actively importing Ida Faber packages in the root Unity project.
• npm.cmd ci in backend/nakama: pass.
• npm.cmd run build in backend/nakama: pass.
