@ -199,6 +199,18 @@ explicit; physical-device listening and endurance remain unqualified.
- Listening tests cover transitions, start/stop behavior, and representative projects.
- Known limitations involving latency and synchronization are documented.
Implemented: documented constant-tempo/fixed-4/4 snapshot policy; absolute timing
and sample-offset regression matrix; configurable audio/scheduled-note boundary
fades; single-owner gain ramps; GUI 5 ms start and asynchronous Pause/Stop fades
with control-thread acknowledgement/deactivation; finite/subnormal output policy;
exact endpoint, block-size, stereo, overload and failure/retry tests. Latency and
synchronization limits are documented in AUDIO_QUALITY.md. Normal/no-JACK,
sanitizer/static-analysis, TSan, GUI/workflow/live JACK and install checks pass.
`make quality-preview` generates matched listening WAVs. Human listening and
physical-device acceptance remain pending; immediate safety/recording/seek paths
and live graph swaps may still click. No tempo/meter map, latency compensation,
limiter or project-format change is claimed.
## Phase 13 — Recording and Recovery
**Goal:** Protect recorded material and handle recording failures predictably.
