Bluetooth: wire existing AudioRouteManager SCO support through both app
variants. Replace binary speaker toggle with 3-way route cycling
(Earpiece → Speaker → Bluetooth). Tauri side adds JNI bridge functions
(start/stop/query SCO, device availability) and Oboe stream restart.
Network awareness: integrate Android ConnectivityManager to detect
WiFi/cellular transitions and feed them to AdaptiveQualityController
via lock-free AtomicU8 signaling. Enables proactive quality downgrade
and FEC boost on network handoffs.
Build: add --arch flag to build-tauri-android.sh supporting arm64,
armv7, or all (separate per-arch APKs for smaller tester binaries).

Documents the feat/desktop-audio-rewrite branch story end-to-end:
- Purpose: shared codebase with android-rewrite via Tauri, platform-
specific audio backends via target-dep sections + feature flags
- Audio backend matrix: CPAL baseline + macOS VPIO + Windows WASAPI
AudioCategory_Communications
- Recent work: desktop direct calling feature with history dedup,
macOS VPIO integration, Windows cross-compile via cargo-xwin, the
libopus/clang-cl vendored audiopus_sys fix, icon.ico generation,
and the WASAPI communications capture backend (task #24)
- Build pipelines: native cargo on macOS/Linux, Docker on SepehrHomeserverdk
for Windows, Hetzner Cloud alternative
- Testing procedures for direct calling parity and Windows AEC A/B
- Known quirks: vendor path relative, cargo-xwin override.cmake clobber,
WebView2 runtime prerequisite, 2024 edition unsafe lint warnings
Also appends shared-doc sections (identical on both branches):
- ARCHITECTURE.md: "Audio Backend Architecture (Platform Matrix)"
- ADMINISTRATION.md: "Build Pipelines"
- USER_GUIDE.md: "Direct 1:1 Calling" and "Windows AEC Variants"
