Map meaning: verified coordinate pins identify independently grounded public visitor/access reference points. Query-only records can be resolved on demand as temporary provider search matches; sensitive records use a deliberately broader agency/locality query. Temporary search matches are not stored as verified coordinates. No map mode is a property boundary, detecting zone, archaeological target, or permission boundary.
