 ### Known Limitations
-The HTML body is truncated at 256 KB per record. Very long pages (e.g., full-text articles with inline images as data URIs) may be incomplete. The `html_length` field always reflects the true size. If you need complete HTML for specific pages, use the `warc_record_id` and `warc_filename` to retrieve the original from Common Crawl.
 Metadata extraction scans only the `<head>` section for performance. Pages that place `<meta>` or `<title>` tags in the `<body>` will have missing metadata.
