+-- How audio.wav stores its channels:
+--   NULL / 'summed' — mic summed into every loopback channel (all pre-2026-07-14
+--                     recordings and every import): one mixed mono-equivalent.
+--   'split'         — stereo, left = microphone ("You"), right = system/loopback
+--                     ("Speaker"), kept separate so diarization runs on the far
+--                     side alone. New mic-enabled recordings.
+-- Diarization, playback (downmix), and bundle export branch on this.
