+- **Category**: server/network
+- **Target path**: `server/network/network-libp2p-server`
+- **Status**: SUPERSEDED-BY-GENESIS-WAVE
+- **Date**: 2026-04-24

+## Summary
+
+Deliver `@suaveplan/network-libp2p-server` on the genesis branch from scratch at enterprise quality. The package provides a server-side libp2p node with TCP + WebSocket transports, noise encryption, yamux stream multiplexing, Kad-DHT peer discovery, GossipSub pub/sub, and a typed `Libp2pServerAdapter` facade. It exposes `start` / `stop`, `subscribe` / `publish` for topic-based messaging, `dialPeer`, and `peers` queries. Genesis adds Zod-validated options, `@suaveplan/error` codes, OTel spans/counters, retry on dial failures, and full integration tests using two in-process nodes.

+## Impact
+
+Downstream: platform network mesh features. Server-only — Node.js required.
+
+**Prerequisites on Verdaccio**: `@suaveplan/error`, `@suaveplan/types`, `@suaveplan/events`, `@suaveplan/retry`, `@suaveplan/logger`.
