* shell: keep fs.mergeVolumes from reverting entries written during the merge The walk reads a page of entries and moves their chunks one at a time, then wrote each entry back unconditionally. A file overwritten in between got its old version back, and the filer deleted the new version's chunks as garbage, so an acknowledged write was lost without any error. The update now carries IF_ENTRY_EQUAL over the entry as the walk read it. When the filer refuses because the entry changed or was deleted, the copies made on the target volumes are deleted, their plan room is released, and the entry is skipped; the source needles stay where the filer still points.

The update now carries IF_ENTRY_EQUAL over the looked-up entry. When the filer refuses because the file changed or was deleted, the moved copies and any new manifest chunks are deleted and the command reports it. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * shell: keep s3.versions.audit -heal from clearing a pointer that just moved The heal cleared the latest-version pointer on the directory entry the walk read, unconditionally. A version written between the audit and the heal has already pointed the directory at a live file, and clearing that pointer hid it. The heal now carries IF_ENTRY_EQUAL over the audited entry and reports a refusal as a failed heal.

The update now carries IF_ENTRY_EQUAL over the entry as read, and a refused entry is skipped and reported.

When one run commits, the other's update is refused, and deleting its copies deleted the needle the committed entry now points at. A refused update now re-reads the entry, resolving its manifests, and deletes only the copies it no longer references. If the entry cannot be read, the copies are left for volume.fsck.

When its update is refused, the claim made every later sibling skip, so the shared chunks stayed on the source volume for the rest of the run. A refused update now releases the claim, and a sibling listed after the change retries the move against the entry as it is now.

They have freshly assigned fids, so they are now deleted with the cookie-checked delete the other orphan cleanups use.

Re-reading the entry before deleting a refused run's copies covers the run that already committed, but not one that commits after that read. With the lock, two applying runs can no longer overlap, as volume.fsck and volume.merge already require. A dry run still works without it.
