every sampled payload found an interior triple-splitting threshold with delta_c_estimate about 2.335 to 2.599, mostly at N=8192 and once at N=512 with a still-tight 0.0148 bracket. Last_split_fraction was 1.0 throughout, last_gap_ratio stayed well above the 3.0 criterion at about 6.22 to 41.66, and the middle-band width remained substantial at about 2.62 to 3.01 instead of collapsing into a nearly binary split.
