Three machines ran timesyncd and one ran ntpd. The module declares timesyncd running with a 50-mesh.conf drop-in (European pool) and ntp absent (hq ADR 0180). A run-once step of its Go binary stops and disables ntpd first and takes out only dangling wants-links, so removing the package leaves no enabled unit pointing at nothing. A provider's drop-in sorting after the mesh's still wins and is reported, not removed. Tools: time_sync_status, _servers, _sync_now (to-be 42 Phase 1).
