The file contains no "Sitemap:" line.

Consequence. Crawlers have to discover every URL by following links. Pages that are deep, newly published, or poorly linked internally take longer to be found, and some may never be. A sitemap is the most direct way to hand a crawler the full list.

If that is not intended. Publish an XML sitemap and declare it with an absolute URL, e.g. "Sitemap: https://example.com/sitemap.xml". The line is global — it belongs outside any User-agent group and applies to every crawler.

A broader rule of the same type already covers these paths.

Consequence. These lines change nothing. They are harmless, but they add length to a file that has a size limit, and they make the real policy harder to read.

If that is not intended. Remove the redundant rules, or narrow the broader rule if it is catching more than intended.

• disallow: /reference-library/L90Already covered by "disallow: /reference-library" on line 89
• disallow: /class/L92Already covered by "disallow: /class" on line 91

The same directive and path appear repeatedly within one group.

Consequence. Duplicates have no effect on crawling, but they inflate the file toward the 500 KB limit and usually signal that the file is generated without dedup.

If that is not intended. Remove the repeats.
