about

nx_research_chem_parse_gate.nx -- broaden the chemistry discoverer from hardcoded element-matrices to a real general capability: PARSE arbitrary chemical formula strings (incl. parentheses like Ca(OH)2) into element counts, build the element-count matrix, and DISCOVER the balancing coefficients (integer nullspace) by search, verified by atom conservation. So "balance this reaction" works for ANY reaction typed as text, not three baked-in matrices. Pure integer, deterministic. GREEN iff 6/6. license_tier: ORIGINAL
