## Title

    A selector is not a second propagation pipeline

## Body

    Observed symptom: A new mirror-to-canonical path can drift from the existing selector and create competing truth. The reusable problem is: A selector is not a second propagation pipeline. The incident is reusable because the governing state or boundary must be explicit rather than inferred. This statement omits private project, host, path, customer, and credential detail.
