This PR fixes the only argument.unresolvableType error and deletes tests/phpstan/baselines/argument.unresolvableType.neon. There is no runtime change.

The error

src/wp-includes/post.php:4726
Parameter #1 $maybeint of function absint contains unresolvable type.

wp_get_recent_posts() still accepts an integer number of posts, which has been deprecated since 3.1.0:

if ( is_numeric( $args ) ) {
	_deprecated_argument( __FUNCTION__, '3.1.0', ... );
	$args = array( 'numberposts' => absint( $args ) );
}

The @param tag documented $args as array only. PHPStan trusts the docblock, so it concluded that is_numeric( $args ) can never be true. Inside that branch, $args has no possible type, and the absint() call receives an unresolvable type.

This error is not a false positive. The docblock was incomplete, because it left out a form that the function still accepts.

The fix

This PR documents $args as array|int and states the deprecation in the description. It does not change the code, because plugins can still pass an integer. No caller in core passes one.

Testing

• composer phpstan reports no errors.
• php -l passes on src/wp-includes/post.php.
• PHPCS reports the same warnings on src/wp-includes/post.php as on trunk.
