Dataset versions use date-style identifiers. A version changes when the row structure, source coverage, formula coverage, or material reference values change.
Dataset landing pages are indexable. Raw JSON and CSV responses are utility distributions and use noindex headers to keep search results focused on readable pages.
Send corrections from the relevant calculator page, including the official source URL and enough context to reproduce the calculation or reference issue.
