Siavash Sameni	5d8e743cbf	feat: Android engine + Kotlin API for direct 1:1 calling ... Rust engine: - start_signaling(): persistent _signal connection, presence registration - Signal recv loop: handles DirectCallOffer, CallRinging, CallSetup, Hangup - New CallState variants: Registered, Ringing, IncomingCall - Stats expose incoming_call_id, incoming_caller_fp, incoming_caller_alias, sas_code - New EngineCommands: PlaceCall, AnswerCall, RejectCall JNI bridge: - nativeStartSignaling(relay, seed, token, alias) - nativePlaceCall(targetFp) - nativeAnswerCall(callId, mode) Kotlin API (WzpEngine.kt): - startSignaling(relay, seed, token, alias) - placeCall(targetFingerprint) - answerCall(callId, mode) — 0=Reject, 1=AcceptTrusted, 2=AcceptGeneric Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>	2026-04-09 06:02:48 +04:00
Claude	26e9c55f1f	feat: Android VoIP client — Phase 1 (audio quality, network adaptation, crate skeleton) ... - New wzp-android crate with Oboe C++ backend, lock-free SPSC ring buffers, engine orchestrator, codec pipeline, and Android Gradle project structure - AEC (NLMS adaptive filter), AGC (two-stage with fast attack/slow release), windowed-sinc FIR resampler replacing linear interpolation (wzp-codec) - Opus encoder tuning: complexity 7 default, set_expected_loss support - Mobile jitter buffer: asymmetric EMA (fast up/slow down), handoff spike detection with 2s cooldown, configurable safety margin - Network-aware quality control: cellular-specific thresholds, faster downgrade on cellular, proactive tier drop on WiFi→cellular handoff, FEC ratio boost during network transitions - Handoff detection in PathMonitor via RTT jitter spike analysis Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>	2026-04-04 18:07:55 +00:00
