nx_gatekit_lib.nx

nx_gatekit_lib.nx -- build fixtures and DRIVE OTHER ORGANS, entirely through syscalls. WHY THIS UNBLOCKS THE LAST SOVEREIGNTY DEBT ------------------------------------------- Every end-to-end gate for the memory plane was a `sh` script run by WSL from PowerShell: Linux shell + Windows host + third-party runtime on the program path, in an estate whose doctrine is bits-up sovereignty and whose own gates are ELF organs. The blocker was real, not laziness: an in-process gate can test a LIB, but an END-TO-END gate must RUN the organ -- create fixtures, invoke the binary with arguments, inspect exit code and resulting files -- and nothing in the plane could spawn a process. Shell was the only tool that could. nx_syscalls has had fork/execve/wait4 the whole time; the gates simply never used them. ★ THE REASON A THIRD-PARTY RUNTIME PERSISTS IS USUALLY ONE MISSING PRIMITIVE, NOT A REAL DEPENDENCY. The shell dependency also CORRUPTED WORK repeatedly in one session, which is the argument made concrete rather than aesthetic: * a generated .sh written with CRLF made `2>&1` a syntax error in dash; * a PowerShell single-quoted Replace put a LITERAL backtick-n into an organ's source, producing "UNRESOLVED identifier 'n'" -- source and deployed binary silently diverged; * a fixture built with `cp` from another test's OUTPUT measured that test instead of its own. None of those failure modes exist when the fixture is written and the child is spawned by syscall. Sovereign: imports only nx_syscalls. license_tier: ORIGINAL
