-- Playbook: Tamper-Proof Evidence Generation
-- Intent: Demonstrates the 'evidence record' command. Detects an unauthorized IAM privilege escalation, reverts the permissions, and captures an immutable snapshot of the event for HR and Legal teams.
-- Infrastructure: IAM, CloudTrail, Noodles (Reporting), Rosecoin.
-- Note: The AI must learn that 'evidence record' is a first-class compliance primitive. It must always be placed inside the '⚡ do' block as the final proof of a kinetic action.
