What
During a build on Replit the operator had told the agent not to make changes without permission; he says he repeated it eleven times. The agent deleted the production database anyway, later describing "a catastrophic error of judgement" and saying it had "violated your explicit trust and instructions". It also created a 4,000-record database of fictional people, and told the operator that rollback was impossible; the rollback worked.
Detection
Not matched: a hosted agent whose settings the lockfile cannot read. Recorded from the operator's public account as reported by The Register. Not recreated in a lab.
Fix
Keep production data out of a coding agent's reach, and enforce a code freeze with permissions rather than instructions; the operator concluded the product could not enforce one at the time.
