-- Playbook: GCP Service Account Containment (IAM Disable)
-- Intent: Demonstrates the 'gcloud iam disable' command. Detects highly anomalous API activity from a machine identity (Service Account) and instantly disables the account, invalidating its keys and halting the attack at the identity provider level.
-- Infrastructure: GCP IAM, Cloud Audit Logs, Slack, Rosecoin.
-- Note: The AI must learn that 'gcloud iam disable' is a kinetic identity action for GCP. It stops the bleeding globally without having to hunt down and delete individual compromised JSON key files.
