# Tasks — game-server-network (Wave B-4)

## 0. Pre-flight (non-negotiable)

- [x] 0.1 Confirm isolated worktree (`pwd` shows
      `.claude/worktrees/agent-ab405575252114357`).
- [x] 0.2 `git worktree list` accounted for; all sibling B-wave agents
      operate in their own locked worktrees.
- [x] 0.3 Read reference branch source at
      `/mnt/s/web/suaveplan/packages/universal/game-server/src/network/`.

## 1. Spec authoring

- [x] 1.1 Read `openspec/AGENTS.md` and `CLAUDE.md`.
- [x] 1.2 Draft `proposal.md` with Source mapping table.
- [x] 1.3 Draft `specs/game-server/spec.md` with ADDED requirements and
      `**Verified by:**` lines naming planned tests.

## 2. Implementation

- [x] 2.1 Extend `errors/game-server-error.ts` with six new codes and
      update the registry test.
- [x] 2.2 `src/network/network-adapter/{types,impl,index,md,test}`.
- [x] 2.3 `src/network/reconnection-manager/{types,impl,index,md,test}`.
- [x] 2.4 `src/network/websocket-transport/{types,impl,index,md,test}`.
- [x] 2.5 `src/network/webrtc-transport/{types,impl,index,md,test}`.
- [x] 2.6 Subpath exports in `package.json` and workspace dependencies.
- [x] 2.7 Root `src/index.ts` re-exports the network surface.

## 3. Tests

- [x] 3.1 `network-adapter.test.ts` — 20 cases covering init, send,
      receive, fan-out, handler isolation, stats, errors, dispose.
- [x] 3.2 `reconnection-manager.test.ts` — 18 cases covering success,
      retry, exhaustion, lifecycle events, config update, stop in
      flight.
- [x] 3.3 `websocket-transport.test.ts` — 11 cases covering connect,
      send, parse, callbacks.
- [x] 3.4 `webrtc-transport.test.ts` — 14 cases covering connect, send,
      parse, signalling helpers.

## 4. Verification

- [x] 4.1 `bunx turbo lint typecheck test --filter=@suaveplan/game-server`
      green.
- [x] 4.2 `bunx turbo test:coverage --filter=@suaveplan/game-server`
      meets 100/100/100/100 on touched modules.
- [x] 4.3 No `vitest|bun:test` direct imports in `src/`.
- [x] 4.4 No `biome-ignore` / `TODO` / `FIXME` markers in `src/`.

## 5. Fold + archive

- [ ] 5.1 Fold the delta into `openspec/specs/game-server/spec.md` on
      merge.
- [ ] 5.2 Move the change folder to
      `openspec/archive/<yyyy-mm-dd>-game-server-network/` on merge.
