Phase 0 cherry-pick regenerated the lockfile from scratch via
`cargo generate-lockfile`, which bumped at least tokio (1.50.0 → 1.51.1)
and downgraded the lockfile format from version 4 → version 3. Many
other transitive deps may have shifted silently.
Symptoms that pointed here:
1. Direct-call media QUIC handshake silently stalls for exactly the
client-side 10s timeout, with no errors in the log. Classic tokio
runtime / async waker mismatch — tasks queued from one runtime
never run because the endpoint's I/O driver is on another runtime.
2. Every `place_call` gets an immediate `signal: Hangup reason=Normal`
back from the signal recv loop, as if it's consuming stale state.
3. Eventually hits `FORTIFY: pthread_mutex_lock called on a destroyed
mutex` and the process dies.
All three are consistent with a tokio async primitive being shared
across runtimes in a way that tokio 1.51.1 handles differently than
1.50.0 (which was the version on the user's known-good build). Rather
than chase the specific bisection, restore the exact base lockfile
and let cargo add only the three deps Phase 0 actually needs
(opusic-c, opusic-sys, bytemuck).
Verification:
- `git diff 8ceb6f4..HEAD -- Cargo.lock | grep -c '^[+-]version = '` → 0
(no version-line changes beyond what Cargo auto-pulls for new crates)
- tokio back to 1.50.0
- rustls, quinn, quinn-proto, quinn-udp all unchanged
- Lockfile version restored to 4
- cargo test -p wzp-codec --lib: 69 passing (unchanged)
- cargo test -p wzp-client --lib: 35 passing + 1 ignored (unchanged)
Does not fix the pre-existing relay-side advertised-IP bug
(CallSetup may still contain a relay address that the callee cannot
reach from its network), but that is an orthogonal issue that existed
on 8ceb6f4 too.

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
