Execution‑Gated Self‑Distillation Rockets Game Code Generation Across Genres
A deterministic launch filter that only passes code that runs on a headless engine drives self‑distillation, boosting a 14B model's clean game generation on unseen families from 8.8% to 42.2%. The study shows that a verifier‑only curriculum outperforms learned judges and eliminates proxy‑score hacking.
