No-Delete Guardrail

Makes every Cowork conversation list its changes before making them, write new versions instead of overwriting, journal everything, and refuse bulk deletes outright.

What it produces

• /Documents/Cowork/output/change-journal.md on OneDrive: an append-only audit log with one row per create, modify, move, rename, archive or delete, including timestamp and approval status.
• Versioned files (report-v2.docx, then -v3, and so on) wherever any step would otherwise have overwritten an existing file.
• An enumerated change list in the conversation before anything is touched, and a per-item approval gate on every destructive action.
• A flat refusal, with alternatives, for any bulk destructive operation (whole folders, "everything older than", more than 10 items at once).

What to say to it

• “Clean up my project folder, but check with me before you remove anything.”
• “Reorganise the Q3 reports folder.”
• “Archive last year's meeting notes.”
• “Replace the old budget file with the new version.”
