Both participants go silent at the exact same moment. The QUIC transport, relay, Opus codec, and FEC are all healthy — the bug is in the lock-free ring buffer that transfers decoded PCM from the Rust recv task to the Kotlin AudioTrack playout thread. + +**Root cause:** `AudioRing::write()` modifies `read_pos` from the producer thread during overflow handling (lines 68-72 of `audio_ring.rs`). This violates the SPSC invariant — only the consumer should own `read_pos`. When both threads write to `read_pos`, a race corrupts the cursor state, causing the reader to see an empty or stale buffer for 12-16 seconds. + +**Full forensics:** `debug/INCIDENT-2026-04-06-playout-ring-desync.md` + +--- + +## Solution: Reader-Detects-Lap Architecture + +The writer NEVER touches `read_pos`.

However, the read-lock path is uncontended 99.99% of the time (write-lock only during destroy), so contention is negligible. + +### Approach B: Defer `destroy()` until audio threads have stopped + +Instead of calling `destroy()` in `teardown()`, set a flag and have the audio threads call `destroy()` after they exit the loop (before parking). + +**Pro:** No locks on hot path. +**Con:** Complex lifecycle — which thread calls destroy? What if both threads race to destroy? Need a `CountDownLatch` or similar. + +### Approach C: Make the JNI handle atomically invalidated + +Use `AtomicLong` for `nativeHandle` and use `compareAndExchange` in `destroy()` + `getAndCheck` pattern in audio calls. + +**Pro:** Lock-free. +**Con:** Still has a TOCTOU window — the thread can load the handle, then it gets CAS'd to 0, then the thread uses the stale handle. Doesn't fully solve the race without combining with a reference count or epoch. + +### Approach D: Introduce a destroy latch + +Add a `CountDownLatch(1)` that audio threads wait on before parking. `teardown()` sets `running=false`, then `await`s the latch (with timeout), then calls `destroy()`. Each audio thread counts down the latch after exiting the loop. + +Actually this needs a `CountDownLatch(2)` — one for each thread (capture + playout). + +**Pro:** Guarantees no in-flight JNI calls at destroy time. No locks on hot path. +**Con:** `teardown()` blocks for up to one frame duration (~20ms) waiting for threads to exit their loops. Acceptable for a hangup path. + +### Recommendation + +**Approach D (destroy latch)** is the cleanest. The 20ms worst-case wait is imperceptible on the hangup path, and it provides a hard guarantee that no JNI calls are in flight when `destroy()` runs. Combined with the existing `running` volatile flag, the audio threads exit their loops within one frame and count down the latch. + +If the latch times out (e.g., AudioRecord.read() is stuck), `destroy()` proceeds anyway — the `panic::catch_unwind` in the JNI bridge will catch the invalid access as a panic rather than a SIGSEGV (though this is best-effort; a true SIGSEGV from freed memory is not catchable). + +## Data Files + +The crash was captured from the Nothing A059 device at 13:05:42 on 2026-04-06.

The OSR stub references a code address (`0x225eb98`) that is no longer valid — likely because the GC moved the compiled code in memory during concurrent compaction. + +## Why This Happens + +Android 16 introduced a new **concurrent mark-compact GC** (CMC) that moves objects in memory while other threads are running. This is safe for normal Java code because ART uses read barriers. But our audio threads have specific properties that stress this: + +1. **`Thread.MAX_PRIORITY`** — audio threads run at the highest priority, starving the GC thread of CPU time. The GC may not complete its thread-flip before the audio thread resumes. + +2. **Tight JNI loops** — `runCapture()` and `runPlayout()` loop every 20ms calling `AudioRecord.read()` / `AudioTrack.write()` via JNI. Each JNI transition is a GC safepoint, but the thread spends most of its time in native code where the GC can't flip it. + +3. **Long-running JIT-compiled code** — the hot loop gets JIT-compiled and may undergo OSR. If the GC compacts memory while OSR is in progress, the stub can reference stale addresses. + +4. **Daemon threads that never exit** — our threads are parked with `Thread.sleep(Long.MAX_VALUE)` after the call ends (to avoid the libcrypto TLS destructor crash). These zombie threads accumulate GC root scan work. + +## Evidence This Is Not Our Bug + +| Component | Evidence | +|-----------|---------| +| **AudioRing** | Not in any backtrace. All crash frames are in `libart.so` (ART runtime) | +| **Rust native code** | `libwzp_android.so` not in any crash frame | +| **JNI bridge** | Crash happens during `ReleasePrimitiveArrayElements` (ART internal), not during our JNI calls | +| **Timing** | Crashes after 476s and mid-call — not during init or teardown | + +## Proposed Fix + +### Option A: Disable concurrent GC compaction for audio threads (recommended) + +Use `dalvik.vm.gctype` or per-thread GC pinning to prevent the mark-compact collector from moving objects referenced by audio threads. + +**Not directly controllable from app code.** But we can reduce GC pressure: + +### Option B: Reduce JNI transitions in audio threads + +Instead of calling `engine.writeAudio(pcm)` / `engine.readAudio(pcm)` via JNI on every 20ms frame, batch multiple frames or use `DirectByteBuffer` to share memory without JNI array copies. + +**Implementation:** +- Allocate a `DirectByteBuffer` in Kotlin, share the pointer with Rust via JNI +- Audio threads write/read directly to the buffer (no JNI call per frame) +- Rust reads/writes from the same memory region +- Reduces JNI transitions from 100/sec to 0/sec per audio direction + +### Option C: Use Android's Oboe (AAudio) natively from Rust + +Skip the Kotlin AudioRecord/AudioTrack entirely. Use Oboe (which we already have as a dependency in `wzp-android/Cargo.toml`) to create native audio streams directly from Rust. The audio callbacks run in native code with no JNI, no GC interaction, no ART. + +This is how the project was originally designed (see `audio_android.rs` with Oboe references) before switching to Kotlin AudioRecord for simplicity. + +**Pros:** Eliminates the entire JNI audio path. No GC interaction. Lower latency. +**Cons:** Requires rewriting `AudioPipeline.kt` into Rust. Oboe setup is more complex. + +### Option D: Pin audio thread objects to prevent GC movement + +Use JNI `GetPrimitiveArrayCritical` instead of `GetShortArrayRegion` to pin the array in memory during the operation. This prevents the GC from moving the array while we're using it. + +**Implementation:** Change `nativeWriteAudio` / `nativeReadAudio` JNI functions to use critical sections. + +### Recommendation + +**Short term: Option B** (DirectByteBuffer) — reduces JNI transitions without major refactoring. + +**Long term: Option C** (Oboe from Rust) — eliminates the problem entirely.

Revert AudioPipeline to use the original ShortArray writeAudio/readAudio path. The DirectByteBuffer JNI functions remain in WzpEngine.kt and jni_bridge.rs for future use once the OSR issue is resolved. The original SIGBUS from ART GC is rare (~1 crash per 8 min call) and doesn't warrant the DirectByteBuffer approach until we can allocate the buffer as a class field outside the hot loop.

Also adds tls_fingerprint() helper (SHA-256 of DER cert, hex with colons) and prints it on startup. This is the prerequisite for relay federation (peers verify each other by TLS fingerprint).

FederationManager: connects to configured peers via QUIC with SNI "_federation", reconnects with exponential backoff (5s-300s), exchanges FederationRoomJoin signals, runs recv loops for both signals and media datagrams, creates virtual participants in rooms. 4.

Fixed the announce/recv flow: outbound link's announce_task sends FederationRoomJoin, peer's inbound signal_task receives it and creates virtual participant. Tested: two relays on localhost with mutual TOML config, client A sends tone via relay A, client B records via relay B — audio received through federation (0.1s/RMS 7291/PASS). Room announcement delay is ~1s (poll interval). The full pipeline: client join → room created → announce_task detects → sends signal → peer receives → creates virtual participant → SFU loop forwards media via room-hash-tagged datagrams → peer demuxes → local delivery.

charset=UTF-8 Content-Transfer-Encoding: 8bit Major rewrite of relay federation replacing virtual participants with a clean router model: 1. Global rooms: [[global_rooms]] in TOML config declares rooms that are bridged across federation. Each relay is a router + local SFU. 2. Room events: RoomManager emits LocalJoin/LocalLeave via broadcast channel when rooms transition between empty and non-empty. 3. GlobalRoomActive/Inactive signals: relays announce when they have local participants in global rooms. Peers track active state and forward media accordingly. Announcements propagate for multi-hop. 4. Media forwarding: separated from SFU loop. Local participant sends via mpsc channel → egress task → forward_to_peers() → room-hash tagged datagrams to active peer links. Inbound datagrams delivered to local participants + forwarded to other active peers (multi-hop). 5. Loop prevention: don't forward back to source relay. 6. Room name hashing: is_global_room() checks both plain name and hash (clients hash room names for SNI privacy). Removed: ParticipantSender::Federation, federated_participants, virtual participant join/leave, periodic room polling. Rooms now only contain local participants. Signaling tested: 3-relay chain (A→B←C) correctly propagates GlobalRoomActive through B to both A and C. Media forwarding plumbing in place but needs final debugging.

ADMINISTRATION.md (587 lines): relay deployment (binary/Docker/systemd), complete TOML config reference, CLI flags table, federation setup (peers/trusted/global_rooms), 3 example configs, Prometheus metrics, auth, identity persistence, 12-item troubleshooting guide. USER_GUIDE.md (459 lines): all clients — desktop (settings, quality slider, key warning, shortcuts), Android (8-level quality slider, server management, identity backup), CLI (flags table, 8 usage patterns). Identity system, quality profiles when-to-use guide.

The `wzp` ALPN protocol identifier distinguishes WZP traffic. - -The tradeoff is approximately 20-40 bytes of additional per-packet overhead compared to raw UDP (QUIC short header + DATAGRAM frame overhead). - -## Why ChaCha20-Poly1305 Over AES-GCM - -1. **Software performance**: ChaCha20-Poly1305 is faster than AES-GCM on hardware without AES-NI instructions. This matters for ARM devices (Android phones, Raspberry Pi relays, embedded systems) where AES hardware acceleration may be absent. - -2. **Constant-time by design**: ChaCha20 uses only add-rotate-XOR operations, making it inherently resistant to timing side-channel attacks. AES-GCM implementations without hardware support often require careful constant-time implementation. - -3. **Warzone messenger compatibility**: The existing Warzone messenger uses ChaCha20-Poly1305 for message encryption. Reusing the same primitive simplifies the security audit and allows key material to be shared across messaging and calling. - -4. **16-byte overhead**: Both ChaCha20-Poly1305 and AES-128-GCM produce a 16-byte authentication tag. There is no size advantage to AES-GCM. - -5. **AEAD with AAD**: The MediaHeader is used as Associated Authenticated Data (AAD), ensuring the header is authenticated but not encrypted.

The header is authenticated but not encrypted, allowing relays to read routing information (block ID, sequence number) without decrypting the payload. + +### Trust on First Use (TOFU) + +Clients remember the relay's TLS certificate fingerprint after first connection. If the fingerprint changes on a subsequent connection, the desktop client shows a "Server Key Changed" warning dialog. The relay derives its TLS certificate deterministically from its persisted identity seed, so the fingerprint is stable across restarts. + +## Relay Architecture + +### Room Mode (Default SFU) + +In room mode, the relay acts as a Selective Forwarding Unit. Clients join named rooms via the QUIC SNI (Server Name Indication) field. The relay forwards each participant's encrypted packets to all other participants in the room without decoding or re-encoding. + +```mermaid +graph TB + subgraph "Room Mode (SFU)" + C1[Client 1] -->|"QUIC SNI=room-hash"| RM[Room Manager] + C2[Client 2] -->|"QUIC SNI=room-hash"| RM + C3[Client 3] -->|"QUIC SNI=room-hash"| RM + RM --> R1[Room 'podcast'] + R1 -->|fan-out| C1 + R1 -->|fan-out| C2 + R1 -->|fan-out| C3 + end + + style RM fill:#ff9f43,color:#fff + style R1 fill:#fdcb6e +``` + +**SFU vs MCU trade-off**: SFU was chosen because it preserves end-to-end encryption (the relay never sees plaintext audio).

Full pipeline verified: - Room correctly identified as global (hash matching works) - Federation egress channel created and connected - GlobalRoomActive signals exchanged between peers - 300 packets (250 source + 50 FEC) forwarded via tagged datagrams - Client B on relay B received full 5-second tone from client A on relay A Added debug logging: is_global check, egress channel creation, per-peer forwarding with active_rooms diagnostic when no match found. Also logs egress packet count (first + every 250th). Multi-hop propagation: GlobalRoomActive signals forwarded to other peers so A→B→C chain knows about rooms across the full mesh.

But active_rooms tracks what PEERS announced (their rooms), not what WE announced. So our own GlobalRoomActive signal went out but our peer_links had empty active_rooms — media was dropped. Fix: for locally-originated media, send to ALL connected federation peers unconditionally. The receiving relay decides whether to deliver to local participants (if it has the room) or forward further. This is correct because federation peers are explicitly configured — if they're connected, they should receive global room media. Multi-hop forwarding (handle_datagram) still filters by active_rooms to prevent loops — only forwards to peers that announced the room.

Previously, each relay computed the hash from the client-provided room name, causing mismatches between relays with different client types. Fix: resolve_global_room() maps any room name (raw or hashed) to the canonical [[global_rooms]] name. global_room_hash() always uses the canonical name for federation hashing. handle_datagram uses both raw and canonical hash matching to find the local room. Also: run_participant now receives the pre-computed federation_room_hash so the egress uses the canonical hash, not the client-specific name.

CLI client now sends raw room names (no hash), matching Android JNI and Desktop Tauri. All three clients are now consistent. 2. When a client joins a global room, the relay merges federated remote participants into the initial RoomUpdate. Previously, clients that joined after the GlobalRoomActive signal only saw local participants. Now they see everyone immediately. 3. Added get_remote_participants() to FederationManager for querying cached remote participants from all peer links.

Room lookup in handle_datagram: hub relay (R2) has no local participants, so active_rooms() was empty and datagrams were silently dropped. Now also checks global_rooms config directly, allowing hub relays to forward without local clients. 2. Multi-hop forwarding: removed active_rooms filter — forward to ALL connected peers except source. The receiving peer decides whether to deliver or forward further. 3. Android relay_label: native RoomMember now includes relay_label from RoomUpdate signal. Kotlin UI reads it for relay grouping.
