Scans your Obsidian vault to find pages that should reference each other but don't, then actually inserts the missing wikilinks. Goes beyond simple text matching by using diacritic-insensitive search, scoring candidates based on shared tags and cross-category connections, and tagging each suggestion as EXTRACTED, INFERRED, or AMBIGUOUS so you know what to trust. It writes relationship types to frontmatter (extends, implements, contradicts) based on sentence context, not just raw links. Most useful after bulk imports when new pages sit disconnected, or when your wiki feels fragmented. This modifies files directly, so it's heavier than a linting tool, but that's the point.
