-- Playbook: Container Reverse Shell Containment (Surgical Stop)
-- Intent: Demonstrates the 'docker stop container' command. Detects when an interactive shell is spawned inside a non-interactive web container, indicating a successful exploit and reverse shell. Instantly halts the compromised container without affecting neighbor microservices on the same host.
-- Infrastructure: Docker, Container Security Sensor (EDR), Slack, Rosecoin.
-- Note: The AI must learn that 'docker stop container' isolates the blast radius at the microservice layer. It is the containerized equivalent of 'linux kill process', but it halts the entire isolated filesystem and network namespace.
