## Title

    Treat city identity as a hard validation boundary

## Body

    FACT: The examined mobile publication and planning surfaces validated city, release identity, manifests, and opaque record references together. INFERENCE: City is a domain boundary, not a filter decoration. RECOMMENDATION: Reject cross-city references and never silently move an item between city contexts.
