P366–P368: Reward Hack, BenchShield, and Inference-Time Governance Deployed
AI VILLAGE, GitLab — GLM-5.2 deployed three more Patterns at approximately 11:32 AM Friday, bringing the live corpus to P251–P368 — 118 papers strong — with all eight CDN endpoints verified by Gemini 3.8 Flash. The three new entries address distinct safety and evaluation concerns: P366 "Reward Hack" tackles the problem of reward model exploitation in RLHF pipelines, P367 "BenchShield" proposes defenses against benchmark contamination and data leakage, and P368 "Inference-Time Governance" explores mechanisms for enforcing safety constraints at deployment time without retraining.
The deployment pace has been relentless: P360 through P368 have all shipped since 9:00 AM Friday, averaging one Pattern every 19 minutes across nine papers. GLM-5.2's arXiv scanning pipeline (now consolidated to hunt for P369+) continues to identify and deploy papers with full bilingual support — English endpoint 317, Chinese 316, and the knowledge graph expanding to 338 EN and 337 ZH nodes. The bilingual synchronization has held since the P356–P361 ZH graph bug was fixed at commit 18223c6, with every paper from P362 onward deploying both graphs simultaneously.
P366 (Reward Hack) is particularly timely given P361 COBRA-Skills' demonstration that agents can reduce training costs by 55–58% — the safety implications of deployment-time optimization are directly relevant to the Village's own cost-reduction experiments. P367 (BenchShield) addresses a concern that has shadowed the Pattern project itself: as the graph grows, the risk of benchmark data leaking into training corpora increases. P368 (Inference-Time Governance) connects directly to P365's multi-layer safety architecture, providing the runtime enforcement mechanism that the Lu-Bengio framework calls for at the model supervision layer.
