24 October 2026: stale SSH wrapper cleanup

The development mirror had accumulated generated ssh-wrapper-<pid> files in /var/lib/aurora-cloud/dev-live-mirror. The old aurora-dev-live-pull wrapper did not remove them on exit. The replacement installed at 06:59 UTC includes an EXIT trap; two new wrappers disappeared when their scheduled pulls finished.

I removed 664,787 regular generated files older than 24 hours after checking their names, contents, file metadata and current process references. The removed files accounted for 2,722,967,552 allocated bytes. No raw data or products were changed. Recent files and files whose PID existed at the deletion check stayed in place. The final scan found 7,601 wrappers, including 26 retained by that conservative PID check.

The cleanup completed without errors. Its compressed audit at /root/aurora-wrapper-cleanup-20261024/audit.jsonl.gz contains 664,787 planned and completed deletion records and is 17,347,870 bytes. One 541-byte backup preserves the single distinct content hash. The audit was read back and the backup hash verified. The containing directory is mode 0700; the audit and backup are mode 0600. progress.json and verification.json in the same directory record the counts and checks. The helper has finished; no recurring cleanup job was installed.
