Layer 1 must remain labelled never-value-evidence. Catalogue R12 is not the differently numbered hyperparameter-inference contract. Do not silently omit this node because the recent DAG focuses elsewhere. Built evidence: Catalogue distinguishes internal and external calibration. Historical V7 census retained 892 records/69 R12 routes, but zero calibration-field/process-identity records; its seven checks and four controls pass only that census scope",
