 == Patch Testing Report ==

 Patch Tested: https://github.com/WordPress/wordpress-develop/pull/9887

 === Environment
 - WordPress: 7.0-alpha-61215-src
 - PHP: 8.2.30
 - Server: nginx/1.29.4
 - Database: mysqli (Server: 9.5.0 / Client: mysqlnd 8.2.30)
 - Browser: Chrome 143.0.0.0
 - OS: macOS
 - Theme: Twenty Eleven 5.0
 - MU Plugins: None activated
 - Plugins:
   * Classic Widgets 0.3
   * Test Reports 1.2.1

 === Steps taken
 1. Applied PR patch locally.
 2. Navigated to Appearance → Widgets → Video Widget.
 3. Clicked "Add Video" → "Insert from URL".
 4. Tested multiple URLs:
    - Valid public YouTube video
    - Private YouTube video
    - Invalid YouTube URL (wrong ID)
    - Invalid Vimeo URL
    - Non-video direct file URL
 5. Compared behavior before and after applying the patch.
 6. ❌ No visible change


 === Expected behavior based on PR
 Specific, contextual error messages should display depending on the
 failure:
 * Invalid URL → show validation message
 * Private/restricted YouTube → show YouTube-specific message
 * Missing file → show file not found message
 * Network issue → show network error message

 Instead, the widget always falls back to the same generic unsupported file
 type message.

 === Additional Notes
 The same generic error message appears both before and after the patch:

 **"Sorry, the video at the supplied URL cannot be loaded. Please check
 that the URL is for a supported video file (.mp4, .m4v, .webm, .ogv, .flv)
 or stream (e.g. YouTube and Vimeo)."**

 ''The newly introduced error messages (invalid_url, youtube_error,
 vimeo_error, network_error, file_not_found) are not triggered or displayed
 in any tested scenarios.''
