Module chat_mesh 

Chat over the SocialWebNet mesh — bridge the chat-graph engine to peer tunnels.

Chat already has a serializable message (RelayEnvelope), a signer, and a transport-agnostic apply path (apply_incoming_envelope). Today those ride the HTTP relay; this module routes them over the mesh instead — peer-to-peer, no relay server.

It composes two lower layers:

• crate::mesh_channel::ReliableEndpoint — per-peer at-least-once delivery + dedup over the (lossy) datagram transport.
• CBOR-encoded RelayEnvelope as the CHAT-port payload.

Like mesh_channel, ChatMeshBridge is a pure state machine: it produces frames to send and envelopes delivered, but performs no socket I/O and touches no storage. The caller moves the frames with SocialWebNet::send_datagram(peer, ports::CHAT, ports::CHAT, frame) and applies each delivered envelope with crate::chat_relay::apply_incoming_envelope. This keeps the routing logic deterministically testable (two bridges exchanging a real envelope, with loss) and decoupled from the live mesh runtime, which lives in qualia-core-db.

Structs

ChatMeshBridge

Per-peer reliable chat routing over the mesh. One bridge per node; it holds a ReliableEndpoint per peer DID.

InboundChat

The result of feeding one inbound frame to the bridge.

OutFrame

A reliable-channel frame destined for a specific peer. The caller frames it as a mesh datagram on ports::CHAT and sends it to peer_did.

Functions

decode_envelope

Decode a CHAT-port payload back into a chat envelope. None if it is not a valid CBOR envelope.

encode_envelope

CBOR-encode a chat envelope for the CHAT-port payload.
