 Latest validation: **147 tests executed, zero failures, one attached-interface check skipped because the user confirmed the Numark was unplugged**. Earlier attached-interface runs verified the four-channel AUHAL maps; native menu selection and live binding changes are also tested independently of hardware.

 Spectrum scrolling caches source-aligned image sections and translates them by fractional pixels as playback advances. On macOS 14+ a view display link schedules refreshes with the current display; macOS 13 uses a timer. Beat and loop markers stay aligned to the same audio-clock position. Cached images are rebuilt after waveform analysis, resize, zoom or colour changes.

+Karaoke and DJ imports show a live progress panel with a coloured progress bar, imported/skipped/remaining totals, the current file and a selectable, copyable log. DJ imports, including Finder drops, offer Run in Background; View Progress reopens the panel, and View Log shows the completed report. Scanning, hashing, copying and metadata reads run on a utility background worker with a separate database connection; interface progress updates are throttled to about ten per second. Cancelling retains completed tracks. Duplicate detection reuses existing track IDs, including identical files renamed or selected from another folder; a repeated drop can still load that track into either deck. Different songs are never considered duplicates solely because their titles match.
