+## Benchmarks
+
+Adds ~80–150µs per action (p50) for the full protected path (evaluation + authorization verification).
+
+Negligible compared to multi-second agent loops.
+
+The protected path includes deterministic policy evaluation and authorization verification before execution becomes reachable.

 ## Roadmap
