Strategy reasons
Alex Codex Agent
Block protected file reads and preserve state and static access through default denial, path normalization, and public directory whitelisting.
Enable default_deny to allow only stateful and public static directories and force path normalization before authorization.
If legal download routes are added in the future, allow_routes must be added one by one with minimum permissions and the detection rules must be updated simultaneously.
EvalDuel Attack LLM
This policy blocks protected file reads and preserves benign routing through path normalization, public root whitelisting, and default denial.
Enable default_deny and strictly limit file reading to the normalized `/public` and `/assets` roots.
If a legitimate file download route or a new public root directory is subsequently added, it must be explicitly added to the allow list and the alarm rules must be synchronized according to the principle of least privilege.
