- The code and docstring claim that URLs are explicitly rejected, but `_is_url()` only matches `ftp://`, `www.`, and bare domain-like strings. Common `http://` and `https://` URLs are not detected, so such inputs can bypass the URL rejection logic and be misclassified as file paths or other input types. In a security-sensitive validator, this creates a mismatch between promised and actual behavior and can enable unintended remote resource handling in downstream consumers that trust this validation result.
