Boundary-Proximity Gating for Multiplier Selection in Safe RL: A Horizon-Limited Operating-Point Comparison — Public Companion Deposit (PGL)

Public companion data deposit for the manuscript 'Boundary-Proximity Gating for Multiplier Selection in Safe RL: A Horizon-Limited Operating-Point Comparison'. Contains the experimental results NPZ archive, publication-quality figures, analysis scripts, and CSV table exports. The deposit covers the main bootstrap non-dominance experiment (B4 vs. LAG frontier, 8 seeds × 150 steps), gate robustness sensitivity grid, and summary statistics. Development ablation results (B0–B4 conditions, transfer environments) are included in a companion NPZ and fully computed — no hardcoded values. Released under CC BY 4.0.
