  "interpretation": "Swap currently occupies about 10.7GiB. This is an observed current component, not a proven attribution of the whole prior 20GB loss. Managed checkout du totals count shared blocks more than once. Verified duplicate retirement recovered only 983040 bytes; other live clones may share blocks. No Data snapshots were found, so do not claim local Time Machine snapshots caused this observed retention.",
