Address security review: reverting to root removed the user:1000 boundary, so add security_opt no-new-privileges:true to block SUID-based escalation. Full cap_drop is intentionally NOT applied — the images' root-init needs CHOWN/SETUID/SETGID to set up /config and /metadata (dropping them reproduces the crash we hit at user:1000).
