The source identity, schema, quality thresholds, selected fields, output publication, and overlap policy must all be explicit and testable before anyone relies on...
At Level 5 Operator, a successful calculation is not enough. You must preserve the source, code, checks, comparison, decision, and published value so another operator can reproduce the claim after its builder has left. This book supplies one deliberately small, standard-library implementation for both a Lab figure...
