d1c96cd71f feat: macOS VoiceProcessingIO for hardware AEC + delay-compensated NLMS
Some checks failed
Build Release Binaries / build-amd64 (push) Failing after 3m33s
Details 
- Add --os-aec flag: uses Apple VoiceProcessingIO audio unit for
  hardware echo cancellation (same engine as FaceTime)
- New vpio feature + audio_vpio.rs: combined capture+playback via VPIO
- Improved software AEC: delay-compensated leaky NLMS with Geigel DTD
  (60ms tail, 40ms delay, configurable via --aec-delay)
- Add --aec-delay flag for tuning software AEC delay compensation
- Add dev-fast Cargo profile (opt-level 2 with incremental compilation)

1b00b5e2a4 feat: improved AEC, keyboard shortcuts, dedup participants, dev-fast profile
Some checks failed
Build Release Binaries / build-amd64 (push) Failing after 3m40s
Details 
AEC improvements:
- Reduce echo tail from 100ms to 30ms (3.3x faster, suited for laptops)
- Add double-talk detection: freeze adaptation when near-end speaks
- Add residual echo suppression
- Disable AEC by default in --android mode (macOS has built-in AEC)

CLI features:
- Keyboard shortcuts: m=mic mute, s=speaker mute, q=quit (raw terminal mode)
- Dedup participants in RoomUpdate display (same fingerprint+alias shown once)
- Add dev-fast profile (opt-level 2 with incremental compilation)

39f6908478 feat: Prometheus metrics on relay + web bridge, client JSONL export (T5-S1/S3/S4) 
WZP-P2-T5-S1: Relay Prometheus /metrics
- RelayMetrics: active_sessions, active_rooms, packets/bytes_forwarded,
  auth_attempts (ok/fail), handshake_duration histogram
- --metrics-port flag spawns HTTP server
- Wired into auth, handshake, session, and packet forwarding paths
- 2 tests

WZP-P2-T5-S3: Web bridge Prometheus /metrics
- WebMetrics: active_connections, frames_bridged (up/down),
  auth_failures, handshake_latency histogram
- Added /metrics route to existing axum app
- Wired into WS connect/disconnect, auth, handshake, send/recv loops
- 2 tests

WZP-P2-T5-S4: Client --metrics-file JSONL
- ClientMetricsSnapshot with all telemetry fields
- MetricsWriter: writes one JSON line per second to file
- snapshot_from_stats() converts JitterStats to snapshot
- --metrics-file <path> flag
- 3 tests

223 tests passing across all crates.

ad16ddb903 feat: WZP-S-2 relay auth + WZP-S-3 featherChat signaling bridge 
WZP-S-2: Relay token authentication
- New --auth-url flag: relay calls POST {url} with bearer token
- Clients must send SignalMessage::AuthToken as first signal
- Relay validates against featherChat's /v1/auth/validate endpoint
- Rejects unauthenticated clients before they join rooms
- New auth.rs module with validate_token() + tests

WZP-S-3: featherChat signaling bridge
- New featherchat.rs module for CallSignal interop
- WzpCallPayload: wraps SignalMessage + relay_addr + room name
- encode_call_payload/decode_call_payload for JSON serialization
- CallSignalType enum mirrors featherChat's variant
- signal_to_call_type maps WZP signals to FC types

Protocol: Added SignalMessage::AuthToken { token } variant

129 tests passing across all crates.

df80ad5343 fix: make cpal/ALSA optional — headless Linux builds work without libasound 
- cpal is now behind an 'audio' feature flag (off by default)
- --live mode requires --features audio at build time
- --send-tone and --record work on headless servers without audio libs
- Linux build script no longer installs libasound2-dev

Build for headless: cargo build --release
Build with mic/speakers: cargo build --release --features audio

79f9ff1596 feat: Phase 3 — crypto handshake, codec2, benchmarks, audio I/O, relay forwarding 
E2E crypto handshake:
- Client/relay handshake via SignalMessage (CallOffer/CallAnswer)
- X25519 ephemeral key exchange with Ed25519 identity signatures
- Integration tests proving bidirectional encrypt/decrypt

Codec2 integration:
- Pure Rust codec2 crate (v0.3) — no C bindings needed
- MODE_3200 (160 samples/20ms, 8 bytes) and MODE_1200 (320 samples/40ms, 6 bytes)
- 11 new tests including encode/decode roundtrip and adaptive switching

Relay forwarding:
- Bidirectional client → remote forwarding with pipeline processing
- CLI args: --listen, --remote
- Periodic stats logging, clean shutdown via tokio::select!

Benchmark tool (wzp-bench):
- Codec roundtrip, FEC recovery, crypto throughput, full pipeline benchmarks
- Sine wave PCM generator for realistic testing

Audio I/O (cpal):
- AudioCapture (microphone) and AudioPlayback (speakers) at 48kHz mono
- CLI --live mode: mic → encode → send / recv → decode → speakers

120 tests passing, 0 failures.

43d7f70fe9 feat: Phase 2 — relay daemon and client library with integration pipelines 
wzp-relay:
- RelayPipeline: ingest → FEC decode → jitter buffer → FEC encode → send
- SessionManager: tracks active calls, idle expiry
- RelayConfig: TOML-based configuration
- Binary: accepts QUIC connections, receives media packets

wzp-client:
- CallEncoder: mic PCM → Opus encode → FEC → MediaPackets
- CallDecoder: MediaPackets → FEC decode → jitter → Opus decode → PCM
- CLI binary: connects to relay, sends test silence frames

99 tests passing across all 7 crates.
