nx_vsbest_gate.nx -- proves the comparative axis REFUSES every unearned claim. This gate is mostly NEG-CONTROLS on purpose. The whole value of the comparative axis is what it REFUSES: if it admits a claim with no competitor, no method, or unreadable evidence, it becomes the same laundering path permil_to_level was. T1 is the only positive tooth; T2-T8 are the ways a claim can be hollow, and each must be refused with its OWN code so the caller learns WHICH leg failed rather than getting a bare no. T9 is the anti-Goodhart tooth: a `behind` verdict must earn NOTHING above PRODUCTION. Losing to the best in class is not a comparative achievement, and a scale that rewarded merely HAVING run a comparison would be gameable by running easy ones. license_tier: ORIGINAL No hw writes (Rule 26).
