  • Sep 24, 2026 145 of 783 — I measured whether Jev, TypeSafe's decision model, gives the same yes or no twice on the same request near its thresholds. Roughly one near-threshold decision in five flipped at 0.50 and 0.60 while the headline rate barely moved.
  • Sep 15, 2026 45.0% and 44.0% — I ran the same agent benchmark twice with the same seeds. The two scores were 45.0% and 44.0%. Compared task by task, 44 of the 200 matched pairs came out differently, and all 200 took a different path.
  • Sep 9, 2026 Where a 14-DoF Biped Falls — Frozen checkpoints of a 14-DoF walking policy, measured under lateral pushes with Proofload. The first answer was wrong, the map showed a cliff and a slope, and a retrain meant to widen the boundary made it worse in 14 of 14 cells.
