Research direction
Start by running the PHP reproducer with strict_types enabled and scalar_implicit_cast true, then trace the argument-type diagnostic logic. Compare the analyzer's result for 'aaa', '111', and 111 with PHP's runtime behavior. Done means the diagnostic consistently accounts for the strict_types condition without regressing other argument checks.
