Reporting broken links and ladder healing
What to do when a source link stops working.
Sources come and go, so occasionally a link will break. If a title's link is dead, use Report broken link on that entry. Your report flags the link so it can be repaired.
Weave also uses ladder healing: when one source stops working, it promotes the next working source for that title so resume still gets you to the content. Reporting broken links helps everyone, because a healthier link ladder means fewer dead ends across the whole catalog.
