The kill switch. The agent stops acting and nothing leaves the environment: action invocations are blocked, deliveries defer, workflow steps park, and writes to memory, files, sessions, cache and Connect are refused. Publishes still queue and approvals can still be decided, so nothing in flight is lost. Applies to the environment this key is bound to -- a staging key cannot halt production.
