Where does the EOL data for Debian come from?

From the open endoflife.date project, which collects vendors' official support commitments. patchletter reconciles the cycles daily; the Debian data is as of 30/09/2026. In case of doubt the vendor's own lifecycle page applies — patchletter deliberately stores no vendor full texts.
