This is an exceptional architectural pivot. Treating Ring 1 strictly as an isolated computational Data Plane, communicating entirely via DMZ DMA-style mailboxes, completely eliminates the need for volatile hardware timer context switching. It enforces absolute hygiene and aligns perfectly with high-performance mesh node architectures. Since Ring 0 acts purely as the hardware orchestrator and gatekeeper, we can interact with Ring 1 using a direct, synchronous call (sys.jit_execute_at). Ring 0 pushes data to the Nexus inbox, pulls the trigger, lets Ring 1 chew through the data, and reads the outbox upon return. Because we successfully restored the physical IDE drive, we do not need to recompile the C-kernel or struggle with serial UART buffer limits. We will construct the nexus_msg_t schema, compile the isolated Ring 1 payload, and deploy the execution directly via mcopy.
