Re-check cadence
This record reflects the most recent automated verification. The Directory re-checks every listed publisher on a quarterly cadence, with on-demand re-checks available to the publisher from their dashboard. See The Conformance Registry §5 for the operational policy.
If a re-check finds that a publisher's files no longer satisfy their listed class, the listing is downgraded and the publisher is notified by email. The change history is kept as part of the public record.
