Wiki Lint

This runs a health check on your Obsidian vault, catching the structural rot that builds up over time. It finds orphaned pages no one links to, broken wikilinks, missing frontmatter fields, and pages whose sources have been updated since you last touched them. The provenance drift check is the interesting one: it flags pages where your ratio of extracted-to-inferred claims doesn't match what the frontmatter says, which matters if you're trying to keep speculation separate from facts. Also catches fragmented tag clusters where pages share a tag but don't actually reference each other. Built for the llm-wiki framework, so it knows to grep frontmatter instead of reading every page. Run this when your vault feels messy or before doing any serious synthesis work.
