Siavash Sameni	ec1bdf3cd5	feat(nat): hard NAT port allocation detection + prediction + HardNatProbe signal (#29) ... Phase A of hard NAT traversal (PRD-hard-nat.md): - PortAllocation enum: PortPreserving / Sequential{delta} / Random / Unknown - detect_port_allocation(): sequential STUN probes from single socket, analyzes port sequence for allocation pattern - classify_port_allocation(): pure function with jitter tolerance, wraparound handling, 60% threshold for noisy sequences - predict_ports(): generates target port range from last_port + delta - HardNatProbe signal message: carries port_sequence, allocation pattern, external_ip for peer coordination - Relay forwards HardNatProbe to call peer - Netcheck gains port_allocation field + format_report display 588 tests pass (17 new), 0 regressions.

Siavash Sameni	8fcf1be341	feat(nat): Tailscale-inspired STUN/ICE + port mapping + mid-call re-gathering (#28) ... Phase 8: 5 new modules bringing NAT traversal close to Tailscale's approach. - stun.rs: RFC 5389 STUN client — public server reflexive discovery, XOR-MAPPED-ADDRESS parsing, parallel probe with retry, STUN fallback in desktop try_reflect_own_addr() - portmap.rs: NAT-PMP (RFC 6886) + PCP (RFC 6887) + UPnP IGD port mapping — gateway discovery, acquire/release/refresh lifecycle, new PeerCandidates.mapped candidate type in dial order - ice_agent.rs: candidate lifecycle — gather(), re_gather(), apply_peer_update() with monotonic generation counter, CandidateUpdate signal message forwarded by relay - netcheck.rs: comprehensive diagnostic — NAT type, IPv4/v6, port mapping availability, relay latencies, CLI --netcheck - relay_map.rs: RTT-sorted relay map, preferred() selection, populate_from_ack() for RegisterPresenceAck.available_relays Relay: CallRegistry stores + cross-wires caller/callee_mapped_addr into CallSetup.peer_mapped_addr. Region config + available_relays populated from federation peers in RegisterPresenceAck. Desktop: place_call/answer_call call acquire_port_mapping() and fill caller/callee_mapped_addr. STUN+relay combined NAT detection. 571 tests pass (66 new), 0 regressions, 0 warnings. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>	2026-04-14 10:17:17 +04:00
