The agent (1.9.0) said nothing when Docker could not be asked and nothing when Docker had no containers, so Steward could tell neither apart from the other, and kept a host's last containers on screen as running either way. - Agent: collect_docker returns (status, detail, containers). "ok" sends docker: [] when there are none; "unavailable" (no socket, nothing listening) and "error" (permission, timeout, bad answer) say why. collect_swarm says whether /info answered, and a node that is not a manager sends swarm_manager: false. A failed /info says nothing. - Ingest: an empty docker list is a snapshot; the newest sample's status goes to the Docker plugin with the rest. - docker_host_status (docker_011): per host, status, detail, since and last report. A host that never had Docker gets no row. - An "ok" empty snapshot reaps the host's containers; an error keeps them. swarm_manager: false drops the host's swarm services and nodes. - Docker page: a "Docker not answering" card names each such host, why, and since when; its containers read as stale. Duplicate header comment in rows.html removed. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

Adds docker_host_status: per host, whether Docker answered at the agent's
|
|
last report (ok / unavailable / error) and why not. Lets Steward show a host
|
|
whose Docker went away as such, instead of its last containers as running
