    The detect mode logs injection attempts as audit events without

    a gain in visibility. Operators opt into stricter ``block`` mode per
    workspace. To disable compliance entirely (not recommended), set
    ``mode: ""`` in config.yaml.

    Before 2026-04-24, the default was ``mode: ""`` (fully off). A
