+# Tasks: enterprise-server-network-hyperswarm
+
+**Change ID**: enterprise-server-network-hyperswarm
+**Package**: `@suaveplan/network-hyperswarm`
+**Target path**: `server/network/network-hyperswarm`
+**Prerequisites on Verdaccio**: `@suaveplan/error`, `@suaveplan/types`, `@suaveplan/events`, `@suaveplan/retry`, `@suaveplan/logger`
+
+---
+
+## 1. Scaffold
+
+- [x] Create directory tree per `proposal.md`.
+- [x] `package.json` at `0.1.0`, `"sideEffects": false`, exports `"."` + `adapter` subpath.
+- [x] Deps: `@suaveplan/error workspace:^`, `@suaveplan/types workspace:^`, `@suaveplan/events workspace:^`, `@suaveplan/retry workspace:^`, `@suaveplan/logger workspace:^`, `zod catalog:forms`, `@opentelemetry/api catalog:observability`, `hyperswarm catalog:network`, `tslib catalog:build`.
+- [x] DevDeps: `vitest catalog:testing`, `@vitest/coverage-istanbul catalog:testing`, `@suaveplan/testing workspace:^`.
+- [x] `tsconfig.json` extending `library-node.json`; `vitest.config.ts` with `createTestConfig()` and `pool: 'forks'`.
+- [x] Scripts: `lint`, `typecheck`, `test`, `test:coverage`, `build`, `docs:check`.
+
+## 2. Types and errors
+
+- [x] Define `HyperswarmOptions`, `HyperswarmOptionsSchema`, peer event handler types in `src/types/hyperswarm.types.ts`.
+- [x] Write `hyperswarm.types.md` (≥200 words).
+- [x] `src/error-codes.ts`: all four error codes with metadata; `registerHyperswarmErrorCodes()`; eager call.
+
+## 3. Adapter implementation
+
+- [x] Implement `HyperswarmAdapter` in `src/adapter/hyperswarm-adapter/hyperswarm-adapter.ts`:
+  - Constructor creates `new Hyperswarm({ keyPair, maxPeers, firewall })`; validates options via `HyperswarmOptionsSchema`; registers event listeners.
+  - `join(topic)`: `swarm.join(toBuffer(topic))` + `await swarm.flush()`; throws `NETWORK_HYPERSWARM_JOIN_FAILED` on error.
+  - `leave(topic)`: `swarm.leave(toBuffer(topic))`.
+  - `send(peerId, data)`: find connection in internal map; write `data`; throws `NETWORK_HYPERSWARM_PEER_NOT_FOUND` if not connected.
+  - `broadcast(topic, data)`: iterate all peers in topic; `send` to each.
+  - `onData` / `onPeerConnect` / `onPeerDisconnect`: register listeners via internal `EventEmitter`; return unsubscribe fn.
+  - `peers(topic?)`: return peer IDs for topic or all.
+  - `peerCount()`: total connected peers.
+  - `destroy()`: `await swarm.destroy()`.
+  - OTel gauge `network_hyperswarm.peer_count`; counter `network_hyperswarm.messages_total`; span per `join` / `send`.
+- [x] Export `createHyperswarmAdapter(options)`.
+- [x] Write `hyperswarm-adapter.types.ts` with internal connection-map types.
+- [x] Write `hyperswarm-adapter.test.ts` (≤500 lines): unit tests with real Hyperswarm instances on loopback (two adapters connecting to each other) — no mocks; send/receive round-trip, peer lifecycle events, destroy cleanup. Skip tests if `SKIP_NETWORK_TESTS=1`.
+- [x] Write `hyperswarm-adapter.md` (≥200 words, simple + advanced, API reference).
+
+## 4. Integration tests
+
+- [x] `tests/integration.test.ts`: multi-peer mesh test — three adapters join same topic, each sends to others, verify all receive; one adapter destroys, others emit disconnect; `{ timeout: 30000 }`.
+
+## 5. OTel + docs
+
+- [x] Gauge `network_hyperswarm.peer_count` updated on connect/disconnect.
+- [x] Counter `network_hyperswarm.messages_total` with `direction` (`sent`/`received`).
+- [x] Span `network_hyperswarm.join` and `network_hyperswarm.send`.
+- [x] Root `README.md`: quick-start, key-pair generation example, multi-peer mesh example, API table.
+
+## 6. Verify and publish
+
+- [x] `bunx turbo lint --filter=@suaveplan/network-hyperswarm` — zero errors.
+- [x] `bunx turbo typecheck --filter=@suaveplan/network-hyperswarm` — zero errors.
+- [x] `bunx turbo test --filter=@suaveplan/network-hyperswarm` — all pass.
+- [x] `bunx turbo test:coverage --filter=@suaveplan/network-hyperswarm` — 100%.
+- [x] `bun scripts/publish.ts --package @suaveplan/network-hyperswarm`.
+- [x] Update `CLAUDE.md`; archive to `openspec/archive/2026-04-24-enterprise-server-network-hyperswarm/`.
