How updates will be handled
Monthly source monitoring will identify changes and their effective dates. Any change to a calculation rule must be implemented, tested against independently verified examples and reviewed before release. Earlier rulesets will be retained for reproducible historical reports. A scheduled source review does not itself update this application.
