Replace the original raw-TCP peer connections and Blowfish/RSA-era design with the YAW/2 protocol stack: Transport - internal/mesh/peer.go: raw TCP + manual ECDH replaced with pion/webrtc DataChannels (ICE, DTLS, SCTP). Peers negotiate via sealed offer/answer/ candidate exchange rather than direct dialling. - internal/nat: deleted — ICE subsumes everything this package was going to do. Signaling - cmd/anchor: new WebSocket signaling server (replaces cmd/relay). Verifies Ed25519 challenge/join signatures, routes opaque nacl/box blobs, broadcasts peer-join/peer-leave events. Never sees plaintext signaling content. - internal/anchor: new anchor client. Manages PeerConnection lifecycle, decides offerer by peer-id comparison, seals/opens signaling payloads with nacl/box, implements mesh.Anchor. Crypto (internal/crypto) - PeerID encoding: base64url → lowercase hex (64 chars, YAW/2 §2). - Sign/Verify: hex signatures throughout. - Added CurvePublicKey/CurvePrivateKey: X25519 keys derived from Ed25519 identity via Montgomery conversion (filippo.io/edwards25519), matching libsodium's crypto_sign_ed25519_*_to_curve25519. - Added SignalingBox/SignalingOpen: nacl/box (XSalsa20-Poly1305) seal/open for signaling payloads. Wire types (internal/proto) - ChatMessage gains Mid (random 16-byte hex) for mesh deduplication (§8). - FileChunk removed from PeerMessage — chunks go on a separate binary DataChannel labelled "f:<xid>"; FileDone added. - New types: SignalingPayload, AnchorMessage, HelloMessage, HelloBindString. - PeerID.Short() now returns first 16 hex chars grouped in 4s. - IPC: CmdConnect removed; CmdJoinNetwork/CmdLeaveNetwork added; EvtSessionReady added (fires when DataChannel opens and hello is received). IPC (internal/ipc) - join_network/leave_network replace connect (direct TCP dial). - Network joins are context-scoped: leave_network or client disconnect cancels the anchor connection cleanly. README updated to reflect new project layout, getting-started commands, IPC protocol, and roadmap state. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
