prune

Remove lock entries that no style/asset pair in the manifest resolves to. These accumulate when an asset is renamed or moved between styles: the old entry keeps claiming the output path the new one now owns, which is what doctor reports as lock-outputs.

Offline. It lists what it would remove, asks for confirmation, and refuses non-interactive removal without --yes. Use --dry-run first. The artwork on disk is untouched and nothing is deleted from the provider account, but the pruned entries' provenance is gone, so those objects read as unclaimed the next time you run salvage.

--style and --only are rejected: prune compares the lockfile against the whole manifest, so a filter would make every entry it excluded look undeclared.
