Architecture Coverage ​

This report maps the ignored extracted PDF pages into topic chapters. Every corpus page is either mapped to a topic or listed as uncovered. Low confidence means the page was in a partial extraction chunk, had too little text, or did not match topic keywords strongly enough.
