E0d — post-correction follow-ups

A. Splitting convergence (is the diffusion negative numerical?)

Equal total diffusion; fine = 8 Trotter steps. Curved toy, 20 seeds, corrected extractor.

n_gal	diff	completeness	Δ vs off (p)

2500	coarse	0.877 ± 0.030	-0.0196 (4.8e-05)
2500	fine	0.880 ± 0.027	-0.0169 (0.00021)

B. Sparsity limit (does the lift ever win honestly?)
