# @suaveplan/game-server - Universal game server framework: typed dependency-injection container, error registry and Zod-validated core types (game-config, session-metadata, player-info, move-validation-result) as foundation for the broader engine/session/state/matchmaking surface migrated from main

Universal game-server framework. Migrated from `@suaveplan/game-server` on
the reference branch `claude/review-game-engine-arch-Kaykr` (main repo
`packages/universal/game-server/`). The port lands in
dependency-ordered slices; this initial slice (`0.1.0`) ships the
foundations that every later slice will depend on:

- **`./errors`** — `GameServerError` + `GAME_SERVER_CODES` (`defineCodes` registry).
- **`./types`** — `GameConfig`, `SessionMetadata`, `PlayerInfo`,
  `MoveValidationResult`, `GameResult`, `SessionType`, `DeepReadonly`,
  plus Zod schemas and throwing/non-throwing validators for every boundary.
- **`./engine/di-container`** — typed singleton/transient service locator,
  ported with a typed `GAME_SERVER.SERVICE_NOT_REGISTERED` error and a
  cache-invalidating re-register semantic (improvement).

## Status of the upstream migration

| Surface area | Status |
|---|---|
| `core/types`, `errors`, `engine/di-container` | Shipped in this slice. |
| `core/{AbstractGameLogic, interfaces/*, events/*}` | Deferred (see spec change `enterprise-game-server-core`). |
| `engine/{GameEngine, GameLoop, PlayerManager, PluginManager, SessionLifecycle, SessionNode, SessionStore, SessionTree}` | Deferred — each requires kebab-case rename, 5-file layout, typed errors, OTel wiring, Zod boundaries, 100% test coverage. |
| `state/{DeltaCompressor, StateDiffer, StateManager, StateSync}` | Deferred. |
| `matchmaking/{MatchmakingEngine, QueueManager, SpectatorManager, skill-matcher, winner-stays-on}` | Deferred. |
| `network/{NetworkAdapter, ReconnectionManager, WebRTCTransport, WebSocketTransport}` | Blocked — missing dependencies `@suaveplan/network-webrtc`, `@suaveplan/network-websockets`. |
| `performance/*` → `telemetry/*` | Deferred (folds into engine slice). |
| `plugins/*` | Blocked — missing dependencies `@suaveplan/workflow`, `@suaveplan/keys`. |
| `enhanced/*` (73 files) | Priority 2 — separate change `enterprise-game-server-enhanced`. |
| `integrations/*` (game-lobby UI + enhanced-server) | Priority 3 — React-coupled, belongs in a `react-game-lobby` package. |

See the design proposal for the
full deferral table and rationale.
