Code/SboxSuperuser/Engine/Authority/HostPolicyService.Protection.cs
Part of HostPolicyService. Caches per-player target protection levels, keyed by SteamID, computed from the resolver's PolicyGraph, the owner set and the caller's claims. The cache clears when the policy graph or owner set instance changes, and when it reaches 256 entries.
