Six-seed registered geometry figure regenerated from results/real/metrics_raw.csv, bias_threshold_geometry.csv, and sign_aware_retention.csv. It reports predominant sign inversion across Qwen and Llama (19/24 family-seed-direction runs, uniform in Qwen), while showing visible Llama exceptions including seed 1: prompted-to-locked is inverted (margin -2.145) but locked-to-prompted is aligned (margin 1.333).
