Preserve audio and artwork while replacing conflicting Opus gain tags with R128 comments. Verify manual, download, and album writes, handle SAF failures, and refresh playback normalization after saving.
Carry the original display name through playback leases to format-aware metadata reads. Cache successful normalization results by source identity, bound the cache, and retry transient read failures.
Add regressions for descriptor hints, album gain fallback, and failed-read retries.
