description: "Checks a debt-validation-notice content-element checklist against Regulation F 12 CFR 1006.34 (the Model Form B-1 element set) and computes the 30-day validation-period response-window math from a declared mailing date under a declared mailing-to-receipt assumption. Same present/absent checklist shape as the shipped official-statement / Metro2 / X12 linters. Checks that declared elements are present and well-formed, not that disclosed amounts are accurate."
