Systemcheck: add file permissions audit

How to check if all files in Debian are installed with the correct permissions? For example, consider a case where a command was accidentally run, such as:

sudo chmod -x /usr/libexec/package-name/script-name

Tools like dpkg --audit, debsums, dpkg --verify do not detect this kind of issue.

Which tool can verify file permissions against the expected values from the package?
