Phase 1 of the big refactor. Escape the Tauri Android __init_tcb+4 symbol leak (rust-lang/rust#104707) by making wzp-desktop's Android .so pure Rust — ZERO cc::Build, no cpp/ files, no C++ in the rustc link step. All future C++ (Oboe audio bridge) lives in a new standalone cdylib crate `wzp-native` which is built with cargo-ndk (the same path the legacy wzp-android crate uses successfully on the same phone + same NDK), copied into Tauri's gen/android/app/src/main/jniLibs at build time, and dlopened by wzp-desktop at runtime via libloading. Changes in this commit: - NEW crate crates/wzp-native/ with crate-type = ["cdylib"] only (no staticlib, no rlib — rust#104707 shows mixing staticlib with cdylib leaks non-exported symbols, which is the original bug source). Phase 1 scaffold has TWO extern "C" functions: wzp_native_version() -> i32 (returns 42) wzp_native_hello(buf, cap) -> usize (writes a string) So we can verify dlopen + dlsym + cross-.so FFI end-to-end before adding any real C++. - desktop/src-tauri/cpp/ directory DELETED (7 files gone). - desktop/src-tauri/build.rs reduced to just the git hash capture + tauri_build::build(). No more cc::Build of any kind. - desktop/src-tauri/Cargo.toml: drop cc from build-dependencies, add libloading = "0.8" as an Android-only runtime dep. - desktop/src-tauri/src/lib.rs Builder::setup() now (on Android only) dlopens libwzp_native.so, calls wzp_native_version() and wzp_native_hello(), and logs the result: "wzp-native dlopen OK: version=42 msg=\"hello from wzp-native\"" If this log appears in logcat when the app launches and the home screen still renders, the split-cdylib pipeline is validated and Phase 2 (port the Oboe bridge into wzp-native) can proceed. - scripts/build-tauri-android.sh: insert a `cargo ndk -t arm64-v8a build --release -p wzp-native` step before `cargo tauri android build`, with `-o desktop/src-tauri/gen/android/app/src/main/jniLibs` so the resulting libwzp_native.so lands in the place gradle will package into the final APK. - Workspace Cargo.toml: add crates/wzp-native to [workspace] members. Phase 2 (separate commit, only if Phase 1 works): - Copy cpp/oboe_bridge.{h,cpp} + getauxval_fix.c from the legacy wzp-android crate into crates/wzp-native/cpp/. - Add cc = "1" as a build-dependency on wzp-native (safe: it's a single-cdylib crate with no staticlib, so no symbol leak). - Add build.rs that compiles the Oboe C++ and the wzp-native Rust FFI exposes the audio start/stop/read/write functions. - wzp-desktop::engine.rs dlopens wzp-native at CallEngine::start, uses its audio functions instead of CPAL on Android.

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
