+Với Codex, `doctor` đọc trạng thái hiệu lực bằng API `hooks/list` của chính
+`codex app-server`. Nếu toàn bộ CASAN hook của project đang `trusted`, kết quả
+là `READY` và không yêu cầu Allow lại. Action `/hooks` chỉ xuất hiện khi hook
+thực sự `untrusted`/`modified`, bị tắt, hoặc máy hiện tại không thể xác minh
+trust state. Hash toàn file `.codex/hooks.json` trong `init-manifest.json` là
+checksum ownership phục vụ uninstall an toàn; nó không phải per-hook
+`trusted_hash` mà Codex dùng để quyết định trust.
