10.4. Cancellation and Recovery

Canceling discovery, analysis, metadata transfer, or generation is cooperative. The current unit of work may take a moment to stop cleanly.

Completed Library analysis is retained. An interrupted current track returns to the durable queue. Canceling Mix generation leaves the previous tracklist in place.

Mix documents are auto-saved and keep bounded revision history. If the current projection needs repair after an interrupted write, Harmonic DJ can recover it from the saved history manifest without placing that private history inside an exported .hdjmix file.
