feat(core): A.6 — supervisor reconnect with watchdog and event stream
Adds an end-to-end auto-reconnect path so a brief network outage no longer leaves the client wedged in a half-dead state. The flow has three layers, each motivated by a real failure mode observed on the Moto G live test: * `chanora_protocol::DisconnectReason` (`UserRequested` / `StreamEnded` / `Error(String)`) is reported on a `oneshot` when the per-connection task exits, so the supervisor can tell user intent apart from a real loss. * `chanora_core` spawns a supervisor task per `ChanoraSession`. It listens for the loss notifier AND runs a watchdog that issues `snapshot()` probes every 5s with a 4s timeout — three consecutive misses synthesise a `DisconnectReason::Error(...)` and trigger the reconnect path. The watchdog catches the "ghost connected" case where tsclientlib silently resets internal state but the event stream never errors. Backoff schedule: 1s, 2s, 5s, 15s, 30s, 60s (capped). On success the supervisor swaps the dead `ProtocolClient` for the new one in place and, if audio was running, restarts the audio engine bound to the new `voice_in`/`voice_out` channels. * `SessionEvent` (Connected / Lost / Reconnecting / Disconnected / AudioStarted / AudioStopped) is broadcast on a 64-slot channel. `chanora_bridge` re-exports it as `BridgeEvent` and exposes `events_stream(StreamSink)`; the Flutter side subscribes from `initState` and renders a reconnect banner with attempt count and delay. New `SnapshotProbe` exposes a clone-friendly snapshot path so the watchdog can probe without holding `&self` across awaits. Localization adds `statusReconnecting` and `statusConnectionLost` keys to `app_en.arb` and `app_zh.arb`. Verified on Moto G Stylus 5G (Android 14) against cn.teamspeak.app: killed Wi-Fi + cellular for ~70 s; watchdog declared loss at three misses, supervisor walked the backoff schedule, and the UI reconnected automatically once the radios came back. Snapshot tree re-rendered without user action. |

feat(alpha): wire connect→snapshot→disconnect end-to-end (v0.1.0-alpha.1)
First Internal Alpha build per DEC-001. Closes the milestone of
'Flutter UI calls Rust via the typed bridge, Rust connects to a
TeamSpeak-compatible server through tsclientlib, returns a typed
snapshot, and disconnects cleanly.' Audio remains Beta scope.
Promotions from PoC:
poc/tsclientlib-connect-spike → crates/chanora_protocol/
New product code:
crates/chanora_protocol/src/{dto.rs,adapter.rs} — typed boundary
over tsclientlib. Tokio task owns the Connection; public
handle communicates via mpsc/oneshot. No tsclientlib types
cross out of the crate (SAD-067 / SysDes-011 / SysDes-029).
core/chanora_core/src/lib.rs — ChanoraSession composes the
protocol crate, enforces the DEC-006 single-connection
invariant.
crates/chanora_bridge/src/{api.rs,frb_generated.rs} — FRB 2.12.0
bridge per DEC-014. cdylib + staticlib + rlib. Typed
BridgeSnapshot / BridgeChannel / BridgeClient / BridgeError
DTOs. Process-wide OnceLock<Runtime> + OnceLock<ChanoraSession>.
flutter_rust_bridge.yaml at repo root.
apps/chanora_flutter/lib/main.dart — Alpha UI: server form,
connect button, channel tree, disconnect.
apps/chanora_flutter/lib/l10n/app_{en,zh}.arb expanded with the
Alpha key set; ARB metadata reaffirms ADR-008 for
server-provided content.
Generated Dart bindings under apps/chanora_flutter/lib/src/rust/.
Empirical verification (2026-05-14):
Workspace: cargo check + cargo test clean
(workspace tests: all green).
Bridge cdylib: target/release/libchanora_bridge.so produced
(~15 MB).
Flutter: flutter analyze clean; flutter test runs 3/3 green
including the alpha_e2e_test that drives the full
Dart → FRB → chanora_bridge → chanora_core → chanora_protocol
→ tsclientlib → UDP → cn.teamspeak.app
path. The captured logcat/stdout shows the tsproto resender
transitioning Connected → Disconnecting → Disconnected on
clean teardown.
Architecture changes:
- Removed the chanora_core ↔ chanora_bridge cyclic dependency.
chanora_core no longer knows the bridge exists; the bridge
maps from CoreError.
- chanora_bridge crate's #![forbid(unsafe_code)] lint relaxed
because FRB-generated glue legitimately uses unsafe at the
FFI boundary. Hand-written code remains unsafe-free.
Open follow-ups (NOT in this Alpha):
- Audio capture/playback wiring into chanora_audio
(Beta scope per DEC-001).
- Identity persistence via chanora_storage
(currently regenerated on every connect).
- Per-message diagnostics + redaction
(chanora_diagnostics still scaffold).
- Reconnect / network-loss recovery.
- Mobile (Android) build of the bridge cdylib + UI verification.
