- config moves into oakcommon as ConfigStore + oakcommon_config_* C
API (INI storage, typed entries, error-handler injection); node and
render call sites keep OAK_CONFIG() macro shape via a local shim
that forwards to the C API; transition config stubs removed
- oakaudio: de-Qt all six classes, C ABI in include/audio with
refcounted handles (processor/manager/waveform/levelmeter/sync,
48 functions); PreviewAudioDevice moved in from render; recording
goes through oakcodec encoder; waveform extract uses probe +
ffmpeg_bridge decode (decode_audio needs M8 task system)
- fix re_sum_samples min/max init bug (values clamped to 0 for
same-sign ranges)
- every C API function has positive + error-path tests; suites:
oakcommon 193, oakaudio 36, oaknode 96, oakrender 42, oakcodec 18
