The URL is declared in robots.txt but does not return a successful response.

Consequence. Crawlers find nothing at the address they were pointed to, so no URLs are submitted. This is worse than declaring no sitemap, because the declaration suggests discovery is covered when it is not.

If that is not intended. Publish the sitemap at the declared URL, or correct the URL to where it lives.

The page answered HTTP 403, so its meta robots tags and X-Robots-Tag headers were not read.

Consequence. Nothing is known about whether this page asks to be kept out of search results. Its absence of directives here proves nothing either way.

If that is not intended. Analyse the page again once it answers normally to our bot.

Every line parses as a directive crawlers understand.

Comfortably within the 500 KB that crawlers will read.
