Route141 Section 7 kernel Frattini closers

This sidecar leaves the routed/public files untouched. It targets the Route141 kernel Route81 least/Frattini atoms by rebuilding the same Section 7 kernel provider from smaller Route141-owned packets.

The new packets keep the manuscript tower:

• choose the least K over the first non-scalar chief factor;
• set R = Phi(K);
• prove the internal nonidentity, centralizer, fourth-power, and elementary Frattini facts through smaller field-level packets;
• reuse the existing literal raw R,M,T,C tower and same-tower simple-head projections downstream.
