Siavash Sameni	d27e85ecf2	feat: SAS (Short Authentication String) for call identity verification ... Derive a 4-digit code from the shared DH secret via HKDF with label "warzone-sas-code". Both peers compute the same code; a MITM relay produces a different one. Users compare verbally during the call. - CryptoSession::sas_code() -> Option<u32> on the trait - ChaChaSession stores and returns the SAS - HKDF derivation in WarzoneKeyExchange::derive_session() - Tests: both peers match, MITM produces different code Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>	2026-04-09 05:48:08 +04:00
Siavash Sameni	51e893590c	feat: WarzonePhone lossy VoIP protocol — Phase 1 complete ... Rust workspace with 7 crates implementing a custom VoIP protocol designed for extremely lossy connections (5-70% loss, 100-500kbps, 300-800ms RTT). 89 tests passing across all crates. Crates: - wzp-proto: Wire format, traits, adaptive quality controller, jitter buffer, session FSM - wzp-codec: Opus encoder/decoder (audiopus), Codec2 stubs, adaptive switching, resampling - wzp-fec: RaptorQ fountain codes, interleaving, block management (proven 30-70% loss recovery) - wzp-crypto: X25519+ChaCha20-Poly1305, Warzone identity compatible, anti-replay, rekeying - wzp-transport: QUIC via quinn with DATAGRAM frames, path monitoring, signaling streams - wzp-relay: Integration stub (Phase 2) - wzp-client: Integration stub (Phase 2) Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>	2026-03-27 12:45:07 +04:00
