about

nx_nettier_gate.nx -- gate for the access-wall network-tier layer (nx_cidr + nx_nettier). Proves CIDR masks, match (pos + neg), LONGEST-PREFIX wins, peer-IP -> tier classification, the DENY-BY-DEFAULT (unknown -> PUBLIC/least-trust) fail-closed default, nt_meets, and the nx_ipaddr reuse (string parse == integer form). Positive AND negative controls. Appends "ACCESSGATE row=nx_nettier net-tier ... verdict=PASS" to knowledge/status/access_gate.log on all-pass. Exit 0 iff all pass. license_tier: ORIGINAL
