The backup engine already drops to the backup user (sudo -E -u $docker_install_user) and backupLocationOwner == $docker_install_user, which is exactly what runFileOp/runFileWrite resolve to in both modes. So convert the raw-sudo data ops (mkdir/chmod/rm/find/cat/grep/mv/chown/tee on backup repos, location configs, keys, manifests) to runFileOp/runFileWrite — creating files as the owner directly, no root chown. backup_verify creates its scratch as the backup user (runFileOp mktemp) instead of chown-after. Binary installs (kopia tar/install, borg dnf) -> runSystem. The 44 sudo -u engine drops stay (already least-privilege; the scoped sudoers will grant them).
