CVE-2026-41523: Python Assert Prefix Validation Bypass

Using `assert` for string validation before usage is vulnerable to a bypass because Python strips assert statements from bytecode when executed with optimizations (`-O`). Attackers can supply inputs that bypass string-prefix boundaries, potentially leading to arbitrary code execution, unintended module loading, or path traversal. Replace the `assert` stateme
