nx_semruler_gate.nx

nx_semruler_gate.nx -- GATE for nx_semruler_lib (the semantic ruler's decision core, /compare/mediaingest). license_tier: ORIGINAL In-process, no fixtures, no network, no filesystem: every subject is arithmetic on planted numbers, so this gate cannot be poisoned by a shared fixture and has nothing to clean up. The subject is the one predicate that did not already exist in the estate -- admissibility -- plus the abstention and the partition, which are the two places a ruler like this normally starts lying. THE TWO TEETH THAT CARRY THE FILE, both written as neg-controls because a green from a subject that could never go red is decoration: neg-control-mirrored-duplicate-is-inadmissible the obvious one-line predicate tests only the copy distance. A mirrored re-upload has a LARGE copy distance and a TINY orient distance, so that version admits every mirrored duplicate and re-measures tier 1 while claiming to measure semantics. This tooth plants exactly that pair (copy 60, orient 2) and requires refusal. It is the tooth that fails if anyone "simplifies" sr_pair_admissible back to a single argument. neg-control-empty-admitted-set-abstains a rate over zero subjects must be UNOBSERVABLE, never 0 and never 1000. A tooth that passes on the empty set is not a tooth, and this is the direction that flatters.
