Comment:

 == Reproduction Report
 === Description
 This report validates whether the reported issue can be reproduced.

 === Environment

 WordPress: 6.9.4-src
 PHP: 8.3.30
 Server: nginx/1.29.5
 Database: mysqli (Server: 8.4.8 / Client: mysqlnd 8.3.30)
 Browser: Chrome 146.0.0.0
 OS: macOS
 Theme: Twenty Twenty-Five 1.4
 MU Plugins: None activated
 Plugins:
 Test Reports 1.2.0

 === Actual Results

 ❌ Error condition does not occur (not reproduced).
 Successfully created a post via POST /wp-json/wp/v2/posts.
 No PHP warnings were observed in logs during or after the request.

 === Additional Notes

 The environment was explicitly switched to the 6.9.4 tag from wordpress-
 develop and rebuilt before testing.
 Debug logging was enabled, but no warnings related to stdClass::$id or
 stdClass::$post_parent were generated.
 This suggests the issue may be environment-specific, dependent on
 additional factors (e.g., plugins, configuration), or not reproducible in
 a clean setup.
