PARAM: rule_id (from the index) or omit to list every published rule. Returns the machine-readable rule: cells, effective dates, issuer document, required qualifiers, what the table does not establish, sha256. The cell values and effective dates are in the file; in a published test, models answered 3/25 dated questions correctly without a source and 25/25 with this file. NOT FOR: rules not in the index, or anything before the effective date.
