Key result
CDN-221 produces 27 forbidden-promotion rows and multiple candidate labels, lacking TTY or biosignature allowances.
Evaluates a new firewall for public claims, suggesting improved validation protocols.
CDN-221 places a hard language boundary on top of the CDN-220 intake harness. Each validator verdict maps to exactly one allowed public claim label. The current fixture set produces seven candidate labels, 27 forbidden-promotion rows, zero observed TTY allowances, and zero entropy or biosignature allowances. Fitted c/f evidence remains fitted-null diagnostic only; GO-6456 remains an external forecast check with no c/f opener; clean future c/f rows remain admissible templates only until populated by observed evidence.
