Compare duplicate owner/subject/revision declarations against every scientific frame pin. Bounded public or synthetic nonpersonal observation metadata only. No names, precise coordinates, sensitive species locations, taxonomy lookup, abundance inference, ecological causation, field instructions or conservation certification. Non-detection is not proven absence; hashes do not anonymize data. Input limit: 32 KiB. Result retention: 24 hours; minimal receipt metadata: 90 days.
