## Title

    The frontend must not synthesize backend semantics

## Body

    Observed symptom: Client guesses about status, identity, or fallback make the UI disagree with canonical API truth. The reusable problem is: The frontend must not synthesize backend semantics. 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.
