nx_lang_h2h.nx

nx_lang_h2h.nx -- THE HEAD-TO-HEAD COMPILER BENCHMARK, SOVEREIGN AND RECEIPTED (2026-09-01). Operator: "nishi lang to get to sota and best of breed and to meet and exceed gcc and rust ... independently verified with evidence documented and our /compare properly storing and making the evidence reproducible". This retires bench/nx_lang_h2h.sh -- shell that built, timed, parsed and judged, the forbidden shape. It builds every arm from source, runs each arm N times, requires every arm to print the SAME checksum, and writes ONE receipt (<out>, the <dom>.bench data class) carrying: host, CPU and kernel; every toolchain's version; every source and binary sha256; min and median microseconds; the checksum; the exact repro command; and a verdict derived by nx_bench_receipt_lib -- the SAME classifier the /compare page and the gate run. Nothing is judged here: an arm whose toolchain is absent is UNMEASURABLE (declared), never dropped; an arm whose checksum differs is VOID (its time is never ranked); a build or run failure names its exit code. The child runner is deliberately NOT tr_run_capture: that primitive merges stderr into the capture (a compiler warning would land inside an emitted .s) and fixes envp to PATH alone (the rustup shim needs HOME, go needs a writable GOCACHE). Same fork/pipe/drain shape, stdout only, envp from the conf -- a different contract, named. usage: nx_lang_h2h <conf> conf keys (line-anchored, nx_lineconf_lib, a missing required key REFUSES): dom= title= workload= home= runs= workdir= srcdir= ref= out= nxcc= nxasm= nxsrc= [gcc=] [clang=] [rustc=] [go=] exit: 0 VALID . 1 VOID (an arm disagrees on the checksum) . 2 usage or conf refusal . 3 UNMEASURABLE (the reference arm or the NishiLang arm could not be measured -- no ratio exists) license_tier: ORIGINAL No hw writes (Rule 26).
