Route production meshes and attached particles from the exact retained PView frame ranges, while keeping the former WorldEntity partition only for standalone tests and explicit diagnostic/oracle probes. Copy retained source/count facts before arena release so world diagnostics no longer require the old partition. Record the accepted G4 visual gate and open the exact G5 production matrix.

Derive attached particle owners from the exact retained PView route stream with a zero-allocation warm path. Correct G4 gate provenance, record the current production-only RDP sample, and keep G5 old-route deletion explicitly blocked until the reapplied retained cutover passes its connected visual gate.
