nx_honesty_grade_lib.nx -- the CYNICAL BAR, shared. Operator directive 2026-07-24: "our graders and judges and census are way too positive about our capabilities ... I want them almost cynical ... to correct the optimism that bleeds in on your side ... or at least incredibly accurate." Root cause: an instrument's author (me) is optimistic about the author's own work, and every grader re-invents its own generous PRESENT bar ("a gate passed on SYNTHETIC data" => "capability PRESENT"). This library is the ONE skeptical bar all graders import so the optimism cannot be re-introduced per-instrument. THE DISCIPLINE (import and call hg_grade instead of awarding a level directly): * DEFAULT SKEPTICAL: the unproven/unknown level is HG_ABSENT(0), never PRESENT. Burden of proof is on the optimistic claim, not on the doubter. * A claim is HONORED ONLY UP TO WHAT ITS EVIDENCE SUPPORTS. hg_grade(claimed, evidence) DOWNGRADES a claim whose evidence carries a stub-tell -- so wording can never lift a toy to REAL/PARTIAL. * levels: 0 ABSENT (nothing real) | 1 STUB (a gate passes on synthetic data; unusable at scale) | 2 PARTIAL (real + usable, sub-incumbent scale) | 3 REAL (production-grade AND live vs non-synthetic reality). "gate passes on synthetic" is capped at STUB, PERIOD. No main, no syscalls -> any grader/census/judge imports it. license_tier: ORIGINAL
