AudioRecorder captures system audio (ScreenCaptureKit) + mic (AVAudioEngine) on a single serial ioQueue, one shared monotonic t0, time-driven writers (pad gaps / trim overlaps) so tracks stay aligned, and an energy mic-VAD for 'self' spans. AudioMixer sums the aligned tracks into mixed_mono_16k.wav. SessionController drives a serialized start/stop state machine, writes the session folder + self_vad.json, exposes live level meters, and finalizes on quit. Hardening from review: ioQueue single-domain (no races), stop() never hangs (mic-first teardown + bounded stopCapture), layout-agnostic mic deep-copy, discard-only video output to keep SCStream alive, VAD lockstep on committed frames, stable signing team in project.yml, single-instance enforcement.
