Approved: The guard prevents malformed AJAX actions from crashing while preserving existing string behavior.

PHP 8.3 execution verified every asserted action shape and the security review found no changed trust-boundary risk.

Validation details

• PHP 8.3 executed the extracted method. Arrays returned true, wpmdb returned false, and other supported inputs returned true.
• The base method threw the reported strpos() TypeError for an array.
• Source inspection found no authorization, capability, nonce, database, file, or outbound-access effect.
• PHP 8.3 syntax checks passed for both changed files.

Untested areas

• The WordPress PHPUnit class was not run because its runtime and Composer dependencies were absent.
