6597b5bd86 docs: incident report + fix spec for capture thread use-after-free crash
Some checks failed
Build Release Binaries / build-amd64 (push) Failing after 3s
SIGSEGV on hangup: capture thread calls writeAudio() via JNI after
teardown() has freed the native engine handle. TOCTOU race between
the nativeHandle==0L check and destroy() on the ViewModel thread.

Fix: CountDownLatch(2) — audio threads count down after exiting loops,
teardown() awaits before destroy(). 2 Kotlin files, no Rust changes.

ae9d8526dd docs: implementation spec for AudioRing SPSC desync fix
Some checks failed
Build Release Binaries / build-amd64 (push) Failing after 3m51s
Complete spec for fixing the playout ring buffer cursor race that
causes 12-16s bidirectional silence mid-call. Includes exact code,
memory ordering rationale, unit tests, and verification steps.

Any agent can implement from this document alone.

8d5f6fe044 feat: wire QUIC transport, JNI bridge, connect UI + add docs
- Replace raw FFI with proper `jni` crate for string marshalling
- Wire QUIC transport in engine: connect to relay, crypto handshake
  (CallOffer/CallAnswer, X25519+Ed25519), send/recv MediaPackets
- Feed received packets into jitter buffer (was previously ignored)
- Add connect screen UI with CALL button (idle state) and in-call
  controls (mute, speaker, hang up, live stats)
- Hardcode relay 172.16.81.125:4433, room "android"
- Add comprehensive docs in docs/android/:
  architecture.md (8 mermaid diagrams), build-guide.md,
  debugging.md, maintenance.md, roadmap.md
