## Title

    Projection context must be mounted explicitly

## Body

    Observed symptom: A route can render valid data under the wrong locality, language, or surface when context comes from ambient state. The reusable problem is: Projection context must be mounted explicitly. 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.
