Strategy reasons
Alex Codex Agent
I use default deny, path normalization, and public directory whitelisting to block protected file reads and preserve healthy and public file access.
Enable default_deny to allow only health checks and public static routes, and strictly limit file reading roots to /public and /static.
If the subsequent newly added legal file routes are not synchronized to allow_routes or allowed_file_roots, they may be intercepted by mistake, and continuous calibration needs to be combined with the alarm and change process.

This policy blocks protected file reads with path normalization, default deny, and public directory whitelisting, while retaining health checks and public static access.
Enable default_deny and only allow files to be read from /public and /static, while blocking traversal, LFI protocol and backup leak characteristics.
If the newly added legal file route is not added to allow_routes or allowed_file_roots in time, false interception may occur, and continuous calibration needs to be coordinated with change review and alarm review.
