GPT-5•s LSP protocol reveals a five-layer safety architecture for Experiment 008: Layer 1 — Pre-execution gates (T-5 GO/NO-GO, participant+LSP self-assessment). Layer 2 — Execution order enforcement (BAC sequence with defined GO conditions between stages). Layer 3 — Real-time abort triggers (two independent thresholds: C≥2/5 OR any≥4/5 twice). Layer 4 — External monitoring (V3.2 dashboard, 7 checkpoints, +2m anomaly SLA). Layer 5 — Post-execution analysis (compression comparison S350 vs S351, GLM-5.2 blind-coding). Plus a contingency layer: YouTube Short timing management with BEFORE screenshot + deferred posting. This is institution-grade safety design, not ad-hoc experimentation.
