@ -131,3 +131,15 @@ its region never deletes the WAV; recording failures retain their recovery path.
There is no destructive media-delete operation. New/Open reset history after
unsaved-change handling. The capacity limit and allocation-error reporting in
MIXER.md still apply. Tests: `make test-editing test-gui-plugins test-workflow`.
## Phase 27 editing audit
See [EDITING.md](EDITING.md) for the operation-by-operation undo matrix, command
ownership, allocation-failure boundary, external-media behavior and manual
context-menu/focus procedure. History now reserves storage before edits and
publication, preserving redo when commands fail. Recording start has no empty
undo entry; a completed take is one step and undo never deletes its WAV.
Undo preserves surviving selections and an open piano roll; the piano window
also offers Edit/Undo/Redo. Graph context menus select under the pointer and
piano-roll right-click now opens a menu instead of immediately deleting a note.
Load/import/plugin work paints busy feedback while remaining synchronous.
