Oboe fails silently to open the AAudio input stream without
android.permission.RECORD_AUDIO, so the call audio would never actually
flow even after phase 3's engine wiring.
- AndroidManifest.xml: declare RECORD_AUDIO and MODIFY_AUDIO_SETTINGS, and
android.hardware.microphone as a required feature. These files are the
cargo-tauri-generated scaffold — nothing in .gitignore excludes them, so
the intended Tauri 2 mobile workflow is to commit them once populated.
- MainActivity.kt: override onCreate to call ActivityCompat.requestPermissions
for the audio perms on first launch. The dialog shows exactly once; the
grant is persisted per-package. onRequestPermissionsResult logs the
outcome so we can spot failures in logcat.
A full native Tauri permission plugin integration is deferred to
Step 6 (polish) together with notifications, icon, and background service.
Spent 10+ builds chasing a __init_tcb+4 / pthread_create SIGSEGV after
adding the oboe audio backend. Every "fix" made things worse. Reverting
all Android-specific files to the state at 35642d1 (build #6), which
was the last commit where the Tauri Android app actually launched,
rendered the home screen, and successfully registered on a relay.
Reverted files (all back to their 35642d1 content):
- desktop/src-tauri/Cargo.toml (no build-dep cc, no tracing-android)
- desktop/src-tauri/build.rs (git hash only, no Oboe / cc build)
- desktop/src-tauri/src/lib.rs (engine cfg-gated on non-android)
- desktop/src-tauri/src/main.rs (two-line desktop entry)
- desktop/src-tauri/src/engine.rs (desktop-only audio setup)
- scripts/Dockerfile.android-builder (no android24→26 clang shim)
- scripts/build-tauri-android.sh (no linker env vars / manifest patch)
Deleted (were added between b314138 and e2e023d):
- desktop/src-tauri/cpp/getauxval_fix.c
- desktop/src-tauri/cpp/oboe_bridge.{h,cpp}
- desktop/src-tauri/cpp/oboe_stub.cpp
- desktop/src-tauri/src/oboe_audio.rs
Next: rebuild image on remote (to drop the baked-in clang shim), build
an APK, install on Pixel 6, verify the UI renders the same way build #6
did. From there we add features back ONE at a time so we can actually
bisect which one triggers the tao::ndk_glue crash. User's rule:
"if you want to change stack, change incrementally, so we can debug".

- New desktop/ directory with Tauri v2 + Vite + TypeScript
- Rust backend: CallEngine wrapping wzp-client audio + transport
- Web frontend: connect screen, in-call screen with participants,
mic/speaker mute, keyboard shortcuts (m/s/q)
- Dark theme UI, settings persistence via localStorage
- Platform-aware --os-aec: warns on Windows/Linux (not yet implemented)
- Workspace updated to include desktop/src-tauri
