An unavailable lookup result can be a persisted prerequisite failure

An unavailable lookup result can be a persisted prerequisite failure, even when the integration successfully returns booleans elsewhere. Trace the displayed reason back through the stored observation and source-bound input selection before treating the symptom as lost provider output. Keep unavailable distinct from false, and separate informational observations from verification decisions. This method identifies the blocked stage; it does not establish what the provider would return with different inputs.
