SCP connects any LLM to any body without retraining. The muscle layer runs at 60fps. The brain wakes only when the muscle cannot handle something. A pattern store learns from every brain decision and replays them locally over time. Result: brain calls dropped from 27 to 0 across 5 adapters including MuJoCo real physics simulation. Pole balanced 64 loops. Brain went silent by loop 17. npm install scp-protocol
