nx_syscalls_gate.nx

nx_syscalls_gate.nx -- THE BASE CONTRACT GATE (arch-board w22 queue row #1: nx_syscalls = 13,307 importers, ZERO direct gate until now; also the mom-3 "never break userspace" hard version). Every sworn wrapper is proven with a REAL KERNEL ROUND-TRIP -- not presence, BEHAVIOR: bytes written are bytes read, forked children are reaped with their exact code, shared pages cross fork, dirents list planted files, negatives FAIL (a gate that cannot fail is not a gate). Composes (fork+exec, fail- closed) nx_syscall_sanity_kat.elf -- the syscall-NUMBER translation KAT from the RV64/x86 collision fix -- so number-mistranslation and behavior regressions are both caught here. Any edit to nx_syscalls.nx must leave this GREEN; the arch board counts it as the base's paired validator. nx_syscalls_gate -- run the battery; exit 0 GREEN / 1 RED license_tier: ORIGINAL module: nishi-core.examiner.syscalls_gate No hw writes (rule 26).
