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"
