pub fn compact_volume_set(root: &Path, out_dir: &Path) -> Result<PathBuf>Expand description
Compact root into out_dir.
A logical volume-set root is rewritten through Q42RolloverPublisher
(or StreamingQ42VolumeWriter when every input may remain Permissive
Commons). A single-file volume is rewritten through the streaming writer
so the result carries PIDX + FIDX + BIDX. The new catalog is published
with the append temp+rename pattern.
