This project breaks the OS impossible triangle. Same-privilege-level isolation via statically-split address spaces. Cross-domain IPC is call + bt + jmp. No kernel code executes during communication. The same security model is theoretically downgradable to systems without an MMU — on an 8086, segment descriptors replace page tables with identical invariants. Full architecture docs and instruction sequences are in the repo.
