Comment:

 == Reproduction Report
 === Description
 This report validates whether the issue can be reproduced. Since the only
 current officially supported version is the last major release of
 WordPress, I tested it on trunk.

 === Environment
 - WordPress: 6.9-alpha-60093-src
 - PHP: 8.2.28
 - Server: nginx/1.27.5
 - Database: mysqli (Server: 8.4.5 / Client: mysqlnd 8.2.28)
 - Browser: Chrome 140.0.0.0
 - OS: macOS
 - Theme: Twenty Twenty-Five 1.3
 - MU Plugins: None activated
 - Plugins:
   * Simple CPT 1.1.0
   * Test Reports 1.2.0
   * WP Dummy Content Generator 4.0.0

 === Actual Results
 1.  ❌ Error condition does not occur (not-reproduced).
 I can see the CPT and its posts in the sitemap.

 === Additional Notes
 - Verified custom post type registration arguments (public, has_archive,
 show_in_rest) in relation to sitemap inclusion.
 - Debugged WP_Sitemaps_Posts::get_object_subtypes to see why CPT is being
 excluded.
 - Tested permalink‑rewrite flush to ensure CPT routing correct for sitemap
 - Reviewed hooks/filters (e.g. wp_sitemaps_posts_query_args) for
 unintended exclusion of CPT posts
 - Checked sitemap pagination logic to see if missing posts fall into pages
 not being generated properly.
 - Test multiple CPT configurations: with and without archive,
 hierarchical, REST support, etc., verifying sitemap inclusion..

 All in all, **make sure that the `public` argument is true** while you
 register the custom pot-type.
