- [x] 0.3 Manifest count matches package set (unchanged — no new packages added).

## 1. Spec authoring

- [x] 1.1 Upstream files read: `GameEngine.ts`, `GameLoop.ts`, `PluginManager.ts`.

- [x] 3.3 `game-engine.test.ts` — covers every scenario in the spec (15 tests).
- [x] 3.4 Every `it(...)` carries `{ timeout: 5000 }`.

## 4. Documentation

- [x] 4.2 README updated — `## Modules` lists the new `.md` files.

## 5. Pre-archive verification

- [x] 5.1 `bunx turbo lint typecheck test --filter=@suaveplan/game-server` — green (82 tests).
