Where the reading begins.
Digna Legi starts with trusted publications, but nothing enters the index on reputation alone. Every article still has to clear the same editorial threshold.
Article cards identify the publisher separately from the newsletter or reading list that led us to it. Explore’s Publisher filter follows the publication, not the import archive.
