---

## 1. Scaffold

- [x] Create directory tree per `proposal.md`.
- [x] `package.json` at `0.1.0`, `"sideEffects": false`, exports `"."` + `adapter` subpath.
- [x] Deps: all workspace and catalog deps 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'`, `setupFiles: ['@suaveplan/testing/polyfills']`.
- [x] Scripts: `lint`, `typecheck`, `test`, `test:coverage`, `build`, `docs:check`.

## 2. Types and errors

- [x] Define `Libp2pServerOptions`, `Libp2pServerOptionsSchema` in `src/types/libp2p-server.types.ts`.
- [x] Write `libp2p-server.types.md` (≥200 words).
- [x] `src/error-codes.ts`: four codes with metadata; `registerLibp2pErrorCodes()`; eager call.

## 3. Adapter implementation

- [x] Implement `Libp2pServerAdapter` in `src/adapter/libp2p-server-adapter/libp2p-server-adapter.ts`:
  - Constructor builds `createLibp2p({...})` config from options — TCP + WS transports, Noise, Yamux, KadDHT (when `dhtEnabled`), GossipSub (when `gossipEnabled`).
  - `start()`: `await node.start()`; throw `NETWORK_LIBP2P_START_FAILED` on error; OTel span.
  - `stop()`: `await node.stop()`; unsubscribe all handlers; OTel span.
  - `peerId()` / `multiaddrs()` / `peers()`: delegate to libp2p node.
  - `dialPeer(multiaddr)`: retry up to `maxRetries` with `@suaveplan/retry`; throw `NETWORK_LIBP2P_DIAL_FAILED` on exhaustion; OTel span.
  - `subscribe(topic, handler)`: GossipSub topic subscription; return unsubscribe fn.
  - `publish(topic, data)`: GossipSub publish; throw `NETWORK_LIBP2P_PUBLISH_FAILED` on error.
  - OTel gauge `network_libp2p.peer_count`; counter `network_libp2p.messages_total`.
- [x] Write `libp2p-server-adapter.types.ts` with internal types.
- [x] Write `libp2p-server-adapter.test.ts` (≤500 lines): two in-process nodes; start/stop lifecycle; dial + subscribe + publish round-trip; peer count updates; `{ timeout: 30000 }`.
- [x] Write `libp2p-server-adapter.md` (≥200 words, simple + advanced, API reference).

## 4. Integration tests

- [x] `tests/integration.test.ts`: three-node mesh — each node subscribes same topic, one publishes, others receive; graceful stop propagates disconnect event; `{ timeout: 30000 }`.

## 5. OTel + docs

- [x] All OTel instrumentation per proposal.
- [x] Root `README.md`: quick-start two-node example, subscribe/publish example, bootstrap peers setup, API table.

## 6. Verify and publish

- [x] `bunx turbo lint --filter=@suaveplan/network-libp2p-server` — zero errors.
- [x] `bunx turbo typecheck --filter=@suaveplan/network-libp2p-server` — zero errors.
- [x] `bunx turbo test --filter=@suaveplan/network-libp2p-server` — all pass.
- [x] `bunx turbo test:coverage --filter=@suaveplan/network-libp2p-server` — 100%.
- [x] `bun scripts/publish.ts --package @suaveplan/network-libp2p-server`.
- [x] Update `CLAUDE.md`; archive to `openspec/archive/2026-04-24-enterprise-server-network-libp2p-server/`.
