#5303 "Swarm page laid out by node: role, resources and the tasks placed on each" A verdict line first, then the nodes that are down or drained and the services short of replicas, then one card per node. A node with a Steward agent shows what its swarm tasks use against the machine's cores and memory, service by service. A node without one lists Swarm's placement, by count. The services table moved to the Docker overview, where it can be filtered. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
