nx_toolhealth_gate.nx -- THE BITE PROOF FOR THE HALF-CAPABLE DETECTOR (lane D, 2026-08-20). nx_toolhealth accuses a registered tool of declaring a verb it does not implement. An accusation organ that has only ever been seen agreeing with its author is unverified, and one with false positives is worse than none -- so this gate plants the known-bad, sees RED, restores, sees GREEN, and separately proves that each ABSTENTION abstains instead of accusing. EVERY FIXTURE IS ASSEMBLED AT RUNTIME under /tmp/<gate>/ and nothing here is a production path. Two reasons, both measured elsewhere in this estate and both load-bearing here: * a gate that shares a fixture with a production beat reports on the FIXTURE, not the code; * THIS subject is a SOURCE SCANNER -- a fixture written as a literal in a production tree would become a subject of the very census under test. nx_toolhealth_gate [subject-elf] -> per-tooth PASS/FAIL then verdict=GREEN|RED (exit carries it) license_tier: ORIGINAL No hw writes (Rule 26). expect_exit: 0
