What we index: The public URL of the file, the text of the link pointing to it, the page title and description of the hosting page, and a snippet of surrounding text. We do not download, store, or mirror the file itself.

Source verification: Files are periodically re-checked to confirm they are still accessible. Pages marked "Active" were reachable at last check. A "Removed" badge means the source URL returned a 404 or similar error.

AI enrichment: For files where the surrounding context is sparse, we use an AI language model to generate a plain-English description of what the file likely contains, based on its filename, extension, and the page content we indexed.
