WHY IT NEEDS A POLICY

Why extract_coredump needs a policy

This tool writes/exports a core dump to a file on the filesystem. It creates new file content but is reversible (the file can be deleted). It does not delete the original coredump, execute code, or perform financial operations. The main risk is that core dumps may contain sensitive memory contents (secrets, credentials, PII) being written to potentially accessible locations.
