Source: The Truth in Lending Act and Regulation Z (12 CFR Part 1026) govern billing-error resolution for credit accounts in the United States. §1026.13 requires a creditor to acknowledge a billing-error notice, investigate, correct the account or send a written explanation of why no error occurred, and refrain from adverse action while the dispute is pending. KYE Protocol™ governs whether a correction / credit / billing-error determination in the dispute flow may PROCEED — under a named owner's recorded authority, with the transaction evidence captured as evidence events at transaction time, with a signed Evidence Pack™, and a recorded contestable determination. KYE™ does not adjudicate whether a billing error in fact occurred, decide whether to fight a dispute, or do fraud scoring. · License: Regulation Z (12 CFR Part 1026) is a US government work in the public domain; the KYE™ registry paraphrases each requirement's intent and cites the official section identifier for mapping purposes only.
