Tauri 2.x Mobile links the app as a cdylib loaded from a Java Activity, so all of the Builder/command code has to live in a library crate. Move the existing logic verbatim into src/lib.rs::run() and reduce src/main.rs to a two-line desktop entry point that calls into it. Cargo.toml gets a [lib] section (crate-types: staticlib + cdylib + rlib, named wzp_desktop_lib) and the wzp-client dependency — which pulls CPAL + VoiceProcessingIO — is moved behind cfg(not(target_os = "android")) so the Android cdylib doesn't need an audio backend yet. Engine-backed Tauri commands (connect/disconnect/toggle_mic/toggle_speaker/get_status) get Android stubs that return clear "not yet wired" errors. The signaling commands (register_signal/place_call/answer_call/get_signal_status/ ping_relay/get_identity) are platform-independent and unchanged. Also: get_identity / register_signal now auto-create the seed if missing instead of erroring with "connect to a room first", and the identity dir resolves to /data/data/com.wzp.phone/files/.wzp on Android (proper app-internal storage) vs \$HOME/.wzp on desktop. Side note: src/main.rs was previously untracked — desktop builds were working only because it existed in the local worktree. This commit fixes that too. Step 1 of the Android rewrite plan (tauri-mobile scaffold). No audio yet. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
WarzonePhone
Custom lossy VoIP protocol built in Rust. E2E encrypted, FEC-protected, adaptive quality, designed for hostile network conditions.
Quick Start
# Build
cargo build --release
# Run relay
./target/release/wzp-relay --listen 0.0.0.0:4433
# Send a test tone
./target/release/wzp-client --send-tone 5 relay-addr:4433
# Web bridge (browser calls)
./target/release/wzp-web --port 8080 --relay 127.0.0.1:4433 --tls
# Open https://localhost:8080/room-name in two browser tabs
Architecture
See docs/ARCHITECTURE.md for the full system architecture with Mermaid diagrams covering:
- System overview and data flow
- Crate dependency graph (8 crates)
- Wire formats (MediaHeader, MiniHeader, TrunkFrame, SignalMessage)
- Cryptographic handshake (X25519 + Ed25519 + ChaCha20-Poly1305)
- Identity model (BIP39 seed, featherChat compatible)
- Quality profiles (GOOD/DEGRADED/CATASTROPHIC)
- FEC protection (RaptorQ with interleaving)
- Adaptive jitter buffer (NetEq-inspired)
- Telemetry stack (Prometheus + Grafana)
- Deployment topology
Features
- 3 quality tiers: Opus 24k (28.8 kbps) / Opus 6k (9 kbps) / Codec2 1200 (2.4 kbps)
- RaptorQ FEC: Recovers from 20-100% packet loss depending on tier
- E2E encryption: ChaCha20-Poly1305 with X25519 key exchange
- Adaptive jitter buffer: EMA-based playout delay tracking
- Silence suppression: VAD + comfort noise (~50% bandwidth savings)
- ML noise removal: RNNoise (nnnoiseless pure Rust port)
- Mini-frames: 67% header compression for steady-state packets
- Trunking: Multiplex sessions into batched datagrams
- featherChat integration: Shared BIP39 identity, token auth, call signaling
- Prometheus metrics: Relay, web bridge, inter-relay probes
- Grafana dashboard: Pre-built JSON with 18 panels
