PFC does not stop at blocking or allowing an action. When an action is allowed, the system can also prove exactly how that decision was derived.
See how PFC connects explored possibilities to the final execution decision with verifiable lineage.
If you want measured hosted evidence for this boundary, see what has been proven live under governed load, mixed allow and deny traffic, and replay freshness probes.
The execution boundary governs the action. Creative lineage verifies the recorded path from exploration to the bound governance decision.
