- Build BridgePolicy/AdmissionContext and PeerMeshConfig once, not per frame.
Dropped on reload, and on the _SERVER_IDS swap an alias refresh does.
- Carry the DMRE timestamp on MeshIngress: the trailer was parsed twice.
- Let the engine be the only one vetting the source; it already answers None.
- Resolve the session and its peer once per datagram instead of 3-5 times.
- Dispatch effects most-frequent-first.
47.1us -> 28.6us per frame on the v5 path. Recorded effects corpus unchanged.
