1// nx_critic_kernel.nx -- the SOVEREIGN, DOMAIN-AGNOSTIC, self-growing CRITIC KERNEL (operator 2026-07-04: 2// "the critic needs to intelligently grow with your tutoring so this whole thing becomes state of the art not 3// just for [photoreal] but audio and industrial design and all kinds of projects"). ONE kernel; every domain 4// plugs in AXES; every axis is held under the epistemic Nishi Critic ([[nx_critic]]) and -- crucially -- CANNOT 5// be trusted (LAW) until it SURVIVES A RED-TEAM: the tutor supplies a GOOD sample AND an ADVERSARY the axis 6// must reject. The kernel RUNS the red-team and only marks the axis red-teamed if it DISCRIMINATES; a gameable 7// axis (adversary not rejected) is caught and queued for the tutor -- so the critic grows intelligently, never 8// self-flatters, and generalizes to visuals + audio + design + anything. 9// 10// PROOF: 3 real domains (VISUAL structure / AUDIO periodicity / DESIGN symmetry), each with a real measurement 11// + a real adversary, all graded by the SAME kernel; PLUS one deliberately WEAK axis (design "detail=variance", 12// which noise games) that the kernel CATCHES and refuses to bless. license_tier: ORIGINAL expect_exit: 0 13import "nx_syscalls.nx" 14import "nx_critic.nx" 15import "nx_itrig.nx" 16import "nx_sdfrender.nx" 17const K_MAGIC_4096: i64 = 4096 18const K_MAGIC_20000: i64 = 20000 19const K_MAGIC_1024: i64 = 1024 20const K_MAGIC_2654435761: i64 = 2654435761 21const K_MAGIC_40503: i64 = 40503 22const K_MAGIC_8191: i64 = 8191 23 24func hw(s: *u8) -> i64 { var n: i64 = 0;
