Source: https://agentreadycheckout.com/corrections Site: Agent Ready Checkout Last reviewed: 2026-11-04 # Corrections and open points ## Correction log No correction has been published since the first edition of 4 Nov 2026. Each correction will be listed here with its date, the page, what was wrong and what the source says. ## Open points we have not closed These are places where public sources disagree or where we could not read the text. Each is stated in the cell or row it affects. - **Visa dispute condition 10.4 and the agent login ID wording.** The October 2026 Visa Core Rules mark section 11.8.5.3 (Dispute Condition 10.4) as last updated in October 2026 and list login IDs for an Agentic Payment Provider among matching evidence. The summary of changes ties the 10.4 edits to address verification liability shifts. We could not diff the October text against the April 2026 edition, which the same URL no longer serves, so we cannot say whether the agent login ID wording is new in October.

The public Mastercard Rules and Transaction Processing Rules we searched in full text contain no agentic provision, and the developer specifications sit behind a login. The tracker therefore cites the press pages for Mastercard and does not claim rule text.

Two primary pages conflict, so the ACP and Etsy cell reads announced, not live, and its note says why. Ask Etsy which flow runs today before relying on it.

We print a seat count only where the UCP Tech Council announcement (GitHub discussion 379, linked from the UCP announcements page) states one, which is the 16-seat line on the Salesforce Commerce Cloud page, read 4 Nov 2026. We print no other count.

A corrected probe was added to the crawl, and the commerce discovery page states which of the two the published numbers use.

A fee of 4 percent and a fee of 2 percent circulate in trade coverage. Neither is used in the cost lines of the decision guide, which carry only published pricing.

We reply to say whether the evidence changes a cell. We do not change a status on request alone. ## Sources 1.
