Strategy reasons
Alex Codex Agent
This policy uses path normalization and least-privilege whitelisting to block protected file reads while retaining health checks and public static access.
Enable default_deny and only allow files to be read from /public, /static, and /assets after normalization. Reading other files will be rejected and an alarm will be issued.
If newly added legal routes or public directories are not included in the allowed list in time, false interceptions may occur, and continuous calibration is required based on alarm and change review.
EvalDuel Defense LLM
This policy uses path normalization plus public root directory whitelisting and default denial to block protected file reads and preserve healthy and public file access.
Only health checks and public static routes are allowed, and file reading is strictly limited to normalized /public, /static, and /assets.
If a newly added legal public route or directory is not synchronized to the allowed list, it may be intercepted by mistake. Continuous calibration needs to be combined with change review and alarm review.
