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

 === Environment
 - WordPress: 6.9
 - PHP: 8.3.29
 - Server: PHP.wasm
 - Database: WP_SQLite_Driver (Server: 8.0.38 / Client: 3.51.0)
 - Browser: Firefox 147.0
 - OS: Windows 10/11
 - Theme: Twenty Twenty-Five 1.4
 - MU Plugins: None activated
 - Plugins:
   * Test Reports 1.2.1

 === Actual Results
 1.  ✅ Unable to reproduce — The reported issue does not occur in this
 environment.

 === Additional Notes

 When creating posts with empty titles:

 - Permalink structure `/%postname%/`: WordPress automatically appends a -2
 suffix to the slug (ie: https://example.com/6-2/). Permalink functions
 correctly.
 - Permalink structure `/blog/%postname%/`: WordPress does not append a -2
 suffix to the slug (ie: https://example.com/blog/6/). Permalink still
 functions correctly.

 Both permalink configurations handle empty post titles without errors.
