# Tasks: enterprise-server-network-trystero-server

**Change ID**: enterprise-server-network-trystero-server
**Package**: `@suaveplan/network-trystero-server`
**Target path**: `server/network/network-trystero-server`
**Prerequisites on Verdaccio**: `@suaveplan/error`, `@suaveplan/types`, `@suaveplan/events`, `@suaveplan/logger`

---

## 1. Scaffold

- [x] Create directory tree per `proposal.md`.
- [x] `package.json` at `0.1.0`, `"sideEffects": false`, exports `"."` + `adapter`.
- [x] Deps: workspace + catalog deps as listed in proposal.
- [x] DevDeps: `vitest catalog:testing`, `@vitest/coverage-istanbul catalog:testing`, `@suaveplan/testing workspace:^`.
- [x] `tsconfig.json` extending `library-node.json`; `vitest.config.ts` with `pool: 'forks'`.
- [x] Scripts: `lint`, `typecheck`, `test`, `test:coverage`, `build`, `docs:check`.

## 2. Types and errors

- [x] Define `TrysteroServerOptions`, `TrysteroServerOptionsSchema` in `src/types/trystero-server.types.ts`.
- [x] Write `trystero-server.types.md` (≥200 words).
- [x] `src/error-codes.ts`: four codes; `registerTrysteroErrorCodes()`; eager call.

## 3. Adapter implementation

- [x] Implement `TrysteroServerAdapter` in `src/adapter/trystero-server-adapter/trystero-server-adapter.ts`:
  - Maintain a `Map<roomId, { room: TrysteroRoom; channels: Map<channelName, DataChannel>; peers: Set<string> }>`.
  - `join(roomId)`: call Trystero `joinRoom(config, roomId)`; register `onPeerJoin` / `onPeerLeave` handlers; update peer set. Throw `NETWORK_TRYSTERO_JOIN_FAILED` on error.
  - `leave(roomId)`: call `room.leave()`; remove from map. Throw `NETWORK_TRYSTERO_LEAVE_FAILED` on error.
  - `send(roomId, channelName, data, peerId?)`: get or create data channel via `room.makeAction(channelName)`; call `send(data, peerId)`. Throw `NETWORK_TRYSTERO_SEND_FAILED` on missing room.
  - `onData(roomId, channelName, handler)`: register action handler; return unsubscribe fn.
  - `onPeerJoin` / `onPeerLeave`: register peer lifecycle handlers; return unsubscribe.
  - `peers(roomId)`: return `[...peerSet]` or `[]`.
  - `leaveAll()`: iterate all rooms, call `leave` on each.
  - OTel gauge `network_trystero.peer_count`; counter `network_trystero.messages_total`.
- [x] Write `trystero-server-adapter.types.ts`.
- [x] Write `trystero-server-adapter.test.ts` (≤500 lines): unit tests using a mocked Trystero `joinRoom` that returns a fake room object — verify all adapter state management, handler registration, unsubscribe. Use DI for Trystero factory to inject mock. Guard network integration tests with `SKIP_NETWORK_TESTS=1`.
- [x] Write `trystero-server-adapter.md` (≥200 words, simple + advanced, API reference).

## 4. Integration tests

- [x] `tests/integration.test.ts`: skip unless `RUN_TRYSTERO_INTEGRATION=1`. Two adapters join same room (torrent strategy); one sends, other receives via `onData`. `{ timeout: 30000 }`.

## 5. OTel + docs

- [x] All OTel instrumentation per proposal.
- [x] Root `README.md`: strategy comparison table, quick-start torrent example, API table.

## 6. Verify and publish

- [x] `bunx turbo lint --filter=@suaveplan/network-trystero-server` — zero errors.
- [x] `bunx turbo typecheck --filter=@suaveplan/network-trystero-server` — zero errors.
- [x] `bunx turbo test --filter=@suaveplan/network-trystero-server` — all pass.
- [x] `bunx turbo test:coverage --filter=@suaveplan/network-trystero-server` — 100%.
- [x] `bun scripts/publish.ts --package @suaveplan/network-trystero-server`.
- [x] Update `CLAUDE.md`; archive to `openspec/archive/2026-04-24-enterprise-server-network-trystero-server/`.
