POSIX sh helper (pkexec target) that mounts/unmounts CIFS shares with strict validation of the unprivileged caller's arguments: mountpoint confined to $HOME or /run/media/<user>, //host/share source, credfile under the caller's runtime dir at mode 0600, whitelisted SMB version/options/modes. Polkit action authorizes it with auth_admin_keep. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
