1// nx_mediaimport_census.nx -- MEASURED benchmark: our polite media importer vs the SOTA image-acquisition tools, 2// grounded on the REAL docs banked by nx_mediaimport_research_fetch (knowledge/fetched/miport_*.raw) + the REAL 3// presence of our organs (ax_have opens the .nx). Grades each capability AHEAD/PARITY/BEHIND. Liar-kill: a pos 4// control (our importer exists) + neg control (bogus organ absent) + corpus-grounded (a raw opened).
