Repair

Scan every album for truncated or partially-downloaded FLACs. Each file is matched to its exact Qobuz recording by ISRC, so a flagged file is genuinely short — not just a different master. You pick which albums to repair; broken files are backed up before being refilled.

Thorough by design: this is roughly one Qobuz API call per track (a gap scan is one call per artist). A 20,000-track library is on the order of a couple of hours, and Qobuz may rate-limit along the way. Run it when you have a known migration or a flaky download session to investigate — not as a recurring sweep.
