nx_rvc_gate.nx

nx_rvc_gate.nx -- THE VERDICT GATE for nishios NO3 (nx_rvc_run_suite, watch symbol rvc_run_suite). SUBJECT: the nx_rvc_run_suite ELF, forked for real (argv[1] overrides; default the serving-root _offc copy). It runs the organ's SELF-CONTAINED `selftest`, which builds a synthetic RV64 program in memory (no third-party corpus, so this gate is non-vacuous on the NAS where there is no gcc): the program stores two known words to a signature region, writes tohost, then loops. The runner's OWN compare core (the same rvc_run_img the real suite uses) is then exercised three ways: good a correct reference -> verdict PASS (T1) corrupt a WRONG reference word -> verdict FAIL (T2, THE KNOWN-FAILING CONTROL: a comparator that always PASSed -- a vacuous suite -- fails HERE, so no pass count can be quoted from a blind ruler) illegal a bad instruction word -> verdict UNSUPPORTED, not a silent PASS/FAIL (T3) empty a nonexistent pin -> zero runs, RED at the caller (T4, neg-control-empty-corpus) T5 requires the runner's own aggregate self-verdict GREEN and exit 0 (partition + all four held). The full per-group compliance numbers (I/M/C/privilege/Zifencei against the pinned repo references) are the LOCAL WITNESS (bench/riscv-arch-test/nishios_NO3_local_witness.txt) -- the third-party gcc assembler and the 12 MB corpus are laptop-only by the estate's no-gcc-on-NAS design; this gate proves the RUNNER MECHANISM everywhere, which is what makes that witness trustworthy. license_tier: ORIGINAL No hw writes (Rule 26). expect_exit: 0
