d424515542 feat: 5-tier quality classification, QualityDirective handling, debug tap stats
Some checks failed
Mirror to GitHub / mirror (push) Failing after 31s
Details
Build Release Binaries / build-amd64 (push) Failing after 3m49s
Details 
- Extend Tier enum from 3 to 6 levels: Studio64k/48k/32k + Good +
  Degraded + Catastrophic with asymmetric hysteresis (down:3, up:5,
  studio:10)
- Handle QualityDirective signals in both desktop and Android engines
  — relay-coordinated codec switching now works end-to-end
- Add periodic TAP STATS to debug tap: packets in/out, fan-out avg,
  seq gaps, codecs seen (every 5s)
- Mark task #2 done (ParticipantInfo in federation signals already
  implemented)

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

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)
