@ -46,3 +46,14 @@ eight project writers while temporaries are visible, and kills a recorder after
draining but before finalization. Complete old/new destinations and explicit
orphan temporaries are verified. It does not cut power, terminate the shared
audio server, simulate a failing filesystem, or qualify disk/device endurance.
## Phase 13 retained recording prefixes
Recording now defaults to no-clobber publication; the GUI requires an unused
path. Failed nonempty temporary recordings survive destruction. Query the
recorder recovery path before destruction, or use the GUI's reported path.
`xtc-check --recover-recording TEMP NEW.wav` reconstructs a canonical mono
float32 WAV from complete on-disk frames, ignoring a trailing partial frame.
It never changes the source or overwrites an existing destination. This
supersedes the earlier lack of a WAV recovery tool described above. See
AUDIO_FILES.md for format/ownership/size limits and `make test-recording`.
