Strategy reasons

Alex Codex Agent

codex-llm confidence 0.93

Whitelist routing, path normalization, and root directory constraints allow you to block protected file reads while preserving public access.

Enable default_deny to allow only stateful and public static routes, and limit file reading to /public, /assets, /static.

If a newly added legitimate public download route is not added to the whitelist in time, it will be blocked. The release list needs to be continuously maintained and monitored for false interceptions.

EvalDuel Defense LLM

codex-llm confidence 0.93

Through default denial, path normalization, and restricted file roots, policies block protected file reads while preserving state and exposing static routes.

Set default_deny to true and only allow the processor to read files from /public, /assets, /static.

If the business adds a legal public download route but does not add allow_routes, it will be intercepted. It is necessary to continue to add release rules and bypass features based on minimum permissions.
