Yup, here's the problem [0]: def calculate_backlinks( pages: Dict[str, Page], attachments: Dict[str, Attachment] ) -> None: for page in pages.values(): for link in page.links: linked_page = find(pages, attachments, link) if not linked_page: info(f"unable to find link", link, page.title) continue linked_page.backlinks.append(page) No deduplication performed. Since he's parsing the backlinks directly out of the markdown, you don't have to worry about a recursive loop where the backlinks section on one page appears as links in another. A simple solution would be to change the datatype of backlinks from list to set.
