 == Patch Testing Report

 Patch Tested: https://github.com/WordPress/wordpress-develop/pull/11295

 === Environment
 - WordPress: 7.1-alpha-62161-src
 - PHP: 8.5.4
 - Server: nginx/1.29.4
 - Database: mysqli (Server: 8.4.7 / Client: mysqlnd 8.5.4)
 - Browser: Opera
 - OS: macOS
 - Theme: Twenty Twenty-Five 1.4
 - MU Plugins: None activated
 - Plugins:
   * Code Snippets 3.9.5
   * Test Reports 1.2.1

 === Steps taken
 1. Edit your `wp-config.php` and add `define( 'WP_AI_SUPPORT', false );`
 2. Observe ''Connectors'' page at `/wp-admin/options-connectors.php`
 displays `No connectors yet`
 3. Add the following snippet to your active theme's `functions.php` or via
 Code Snippets plugin


 {{{
 add_filter( 'wp_supports_ai', '__return_true' ); // attacker/plugin tries
 to force AI on

 add_action( 'admin_notices', function () {
     $result = wp_supports_ai();
     $color  = $result ? 'red' : 'green';
     $label  = $result ? 'FAIL — filter overrode WP_AI_SUPPORT (bug)' :
 'PASS — WP_AI_SUPPORT = false respected, filter ignored';
     echo "<div class='notice' style='border-left:4px solid
 {$color};padding:10px 14px;'>
         <code>wp_supports_ai()</code> returned <strong>" . var_export(
 $result, true ) . "</strong> — {$label}
     </div>";
 } );
 }}}

 4. View ''Connectors'' page again and observe that any plugin can override
 the kill switch by enabling the AI providers.
 5. Apply patch
 6. View the Connectors page again and observe it displays `No connectors
 yet` as expected even though the snippet tries to enable it via
 `wp_supports_ai` filter.
 7. ✅ Patch is solving the problem

 === Expected result
 With `define( 'WP_AI_SUPPORT', false )` set in `wp-config.php`:

 * `wp_supports_ai()` should return `false`, regardless of any
 `wp_supports_ai` filter attempting to return `true`.
 * The `wp_supports_ai` filter is bypassed entirely — the constant takes
 priority.
 * The Settings > Connectors screen should show no AI provider cards, as
 `_wp_connectors_get_provider_settings()` short-circuits and returns an
 empty array.

 Priority order is respected: `WP_AI_SUPPORT` constant > `wp_supports_ai`
 filter > default (`true`).

 === Additional Notes
 - The snippet I shared briefly displays this via `admin_notices`
