Concerns: pushword/core, pushword/flat
Cached Markdown and TOC fragments now expire after 30 days and are pruned daily during normal traffic. The first cache access clears legacy fragments that had no expiration. Nothing to do.
Creating var/app.db~… through pw:backup --create, pw:flat:sync --backup, or bulkContentEdit now keeps the ten newest backups and removes older copies. Nothing to do.
