@ -135,3 +135,24 @@ draw/move/resize notes, save/reopen and render them. The live MIDI target connec
only software clients and checks on/off, panic, disconnect, and saved-note
playback/seek. It needs an existing JACK-compatible server. No hardware routes
or system changes are made. MIDI recording/SMF and physical devices are deferred.
## Phase 8 verification
```sh
make all test gui debug test-gui test-gui-jack test-jack-audio test-jack-midi
make BUILD_DIR=build/nojack PKG_CONFIG=false all test gui test-gui
```
`test_mixer` covers stereo gain/pan, mute/solo, sample automation, block
independence, WAV and graph routing, v4 persistence failures and bounded history.
GUI tests add automation mouse edits, mixer keys, history rollback/branching and
save/reopen. The existing live MIDI test now uses two software capture ports and
checks hard-right saved-note playback and output meter snapshots; mono audio
record/play acceptance remains covered. A native Xvfb mouse smoke check confirms
sliders and automation drawing. See MIXER.md for capacities and deferred features.
The fresh Phase 8 verification build, no-JACK core/GUI suite and Clang
ASan/UBSan core/GUI suite passed without compiler warnings. GUI leak checking
retains only the existing fontconfig suppression. ThreadSanitizer also passed
the recorder concurrency and realtime publication tests. Physical devices and
long-running stereo performance remain unverified.
