It takes markdown from Roam or Obsidian, identifies asset links based on file references, uses stored SuperBase asset URLs, and replaces the original links in the markdown. A key subtlety is that Roam link patterns depend on asset type partly determined by MIME type, so a MIME type library was added (about 23k right now) as a first approximation. If the source is Obsidian, it uses a single link pattern and detects the type of file to decide the correct Roam markdown output, with testing also mentioned.
