Bug

In the featured_article_snapshot_id view, the field featured_article_snapshot_id is taken as if it was unique by row, but it is not.

This can be easily checked with this query :

SELECT * FROM (
    SELECT featured_article_snapshot_id, json_group_array(snapshot_id), COUNT(*) as count
    FROM snapshot_apparitions
    WHERE is_main -- Not required
    GROUP BY featured_article_snapshot_id
)
WHERE count > 1

Among other things it leads to "deadends" while browsing the UI, likely because the timestamp search and time diff relies on this false assumption.
