The node restarted once on the kept datadir at 11:17:54Z to add build-1's two hands as peers (the three hubs gave it one peer); the harness's sync seconds count from that restart; 1 h 25 min wall from the fresh start. Node RSS peaked 6.0 GB against the container's 31 GB cgroup limit (guard idle). The hub evidence (lp-05) is the network watch's line."
