Detailed Analysis

Warning

No sitemap is declared

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.

Notice

1 rule can never take effect

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.
