Edition 3.1, closed on 2026-09-25. The facts on this page are dated as of 2026-09-23, the date they were last read against their sources; the close re-read none of them. This page is not updated after the closing date unless a later edition says so.

## Freshness

Every page and payload carries its own valid_as_of, and they are not all the same
date: read the field on the page or payload you are using, never a site-wide one.
The Rubric and the Register were checked most recently, on 2026-09-23; the other
pages carry earlier dates. This is Edition 3.1, closed on 2026-09-25: no page is
updated after that date unless a later edition says so. US rulemaking was live at
the last check and processor terms change; read a page past its date as history.
