libmesh

libmesh is a QUIC-native peer reachability layer for Zig.

It provides:

• identity-bound peer discovery
• setup signaling between peers
• authenticated relay fallback

Stack Position

libself -> who is this peer?
libmesh -> where is this peer and how do I reach them?
libdice -> can I establish a direct path?
libfast -> run QUIC on the chosen path

libmesh depends directly on:

• libself
• libfast

libmesh does not directly depend on:

• libdice
• libflux
• liblink

Public API

lib/mesh.zig exposes high-level entry points:

• publishSelf(...)
• lookupPeer(...)
• lookupPeerAt(...)
• expirePeers(...)
• signalPeer(...)
• openRelayRoute(...)
• resolveRoutes(...)
• connectPeerViaDriver(...)
• connectPeerViaDriverDefault(...)

Route Boundary

• libmesh carries peer metadata, signaling, and relay fallback.
• libdice performs ICE/STUN/TURN direct path establishment externally.
• libfast runs QUIC over direct or relayed route.

Connection Policy

Default route policy is:

1. direct endpoint
2. signaling + external libdice when traversal is needed and available
3. relay fallback when direct path cannot be used
