nx_zeroprint_gate.nx

nx_zeroprint_gate.nx -- teeth for nx_zeroprint (the zero-prints-as-NUL detector/repairer). The subject's whole job is to tell four look-alike shapes apart, so the fixture carries ALL FOUR and the gate asserts each bucket by name. Three of them MUST come back SAFE; a detector that flagged them would be a false-positive generator, and the estate's own first census of this defect (written in Python) did exactly that -- it could not see the else-form and over-counted by six. EVERY FIXTURE IS ASSEMBLED AT RUNTIME under /tmp/nx_zeroprint_gate/, never shared with a beat and never committed as a file: a detector that scans source WILL find its own test fixture, and a fixture written into the tree would make this gate flag itself forever. T1 is the anti-vacuity tooth: if the planted defect is NOT detected, nothing below proves anything. license_tier: ORIGINAL expect_exit: 0
