* fix(diag): record bridge events in diagnostics page
Connection lost/reconnecting/disconnected and iOS audio interruption
events now appear in the diagnostics dialog alongside existing error
snackbar entries.
* fix(diag): reduce audio callback sample verbosity to debug
The render callback diagnostic sample logged every 100 callbacks
(~2s) at INFO level, flooding the 256-entry release log buffer and
pushing out useful events. Changed to DEBUG so it only appears in
debug builds with the larger 4096-entry buffer.
* fix(diag): add timestamps to Rust diagnostic log entries
* build: add silero-coreml as git submodule
Replaces sibling-directory local package with in-repo submodule.
Updates Xcode relative paths and CI checkout to fetch submodules.
* build: add silero-coreml submodule
Clarify ONNX Runtime guidance with direct-open install hints, restore desktop WebRTC VAD visibility, map mouse side buttons through focused PTT capture/runtime paths, and wait for server acks before showing chat sends as successful.
Constraint: Linux release UX must stay functional when ONNX Runtime is optional and GNOME portal availability varies
Rejected: Keep desktop VAD locked to Silero only | misleads users when ONNX Runtime is skipped
Confidence: medium
Scope-risk: moderate
Directive: Preserve the protocol send-ack wait path for chat so UI success always tracks real server acceptance
Tested: flutter analyze lib/main.dart lib/widgets/chat_views.dart lib/widgets/input_dialogs.dart lib/widgets/startup_dependency_screen.dart; flutter test test/widgets/input_dialogs_test.dart test/widgets/chat_views_test.dart test/services/startup_dependency_check_test.dart test/widgets/startup_dependency_screen_test.dart test/widgets/voice_settings_controls_test.dart test/widgets/audio_processing_config_state_test.dart; cargo test -p chanora_protocol --lib; cargo test -p chanora_audio ptt_backends --lib
Not-tested: Live manual GNOME portal rebind/global PTT on a real desktop session; observer-bot chat against a live server after the sender-name fallback change
Constraint: SRS-163 requires Android back to be handled by the shell/platform layer, and the Dart service existed but was not wired into the live app.
Rejected: Leave BackIntentService test-only and unwired | System back would bypass app policy on Android.
Confidence: medium
Scope-risk: narrow
Directive: Keep back-intent probe state in sync with every new dialog or pushed route added to the Flutter shell.
Tested: dart format apps/chanora_flutter/lib/main.dart; flutter analyze lib/main.dart test/services/back_intent_service_test.dart; flutter test test/services/back_intent_service_test.dart
Not-tested: Manual Android device back-navigation smoke test
