#5209 "Docker views: readable names, CPU/memory in cores and bytes, failures
listed with since-time" (milestone 477 "UI problems first").
- A swarm task reads as its service and slot ("codex_db · 1", or the node
for a global service), with the raw name in the title: Docker page, host
panel, busiest widget, container detail.
- CPU reads in cores (Docker's 100% = one core), toned by its share of the
host's CPUs from the agent's per-core series. Memory reads in bytes, against
a limit only when one is really set (Docker reports host RAM otherwise).
- Exit 137/143 without an OOM kill is a stop, not a failure: no
exited_nonzero, no crash-loop death, no "failed (24h)", dim exit code.
- "Failed (24h)" is a list (Docker page #failures, linked from the widget
and the tile): plain containers by their deaths, swarm services by Swarm's
failed tasks; a second manager's copy of a task death counts once.
- Failing swarm services lead Needs attention; services sort problems first
with since-times on the page, the widget and the Swarm page; nodes that
are down or drained sort first.
- Busiest widget orders by a 5-minute CPU average so the list holds still.
- Host panel: a table, problems first with what is wrong and since when;
replaced swarm tasks hidden and counted.
- Container detail: node hostname, I/O labelled "since start", Restarts
hidden for swarm tasks with a note on where task failures are.
- Widget names: "Docker — Services & failures", "Docker — Busiest containers".

Traefik: routers are graded from their latest scrape (router_state: crit on
any real 5xx share, warn on p95 past the latency critical cutoff or a high
4xx share). Failing and slow routers lead as cards that say why; healthy
ones fold into one table that stays open or shut across polls. Proxy
counts are stat tiles; certificates are graded by Settings -> Thresholds
(tls_days).
UniFi: WAN health is a stat strip (latency graded by the thresholds),
devices carry status dots, event categories and firewall actions are
badges, the alarm count reuses .count-badge (renamed from .nav-count).
SNMP: each device wears a status badge and its readings are stat tiles.
Agent fleet: the table comes first, with a Status column (Reporting /
Silent / Never reported, by the host page's stale_after_seconds), silent
agents first, hosts linked, last seen as |ago.
Audit: entries name their entity (one query per type, steward/audit/
service.py) and link it; something deleted since keeps the name its entry
recorded and says "(deleted)".
Tokens: charts read colours through chart-colors.js (stewardColor resolves
a token to the rgb the browser computed; Chart.js defaults take the page's
text and border colours), so host, history, Traefik and SNMP charts drop
their hex. Template hex colours reach 0 (HEX_CEILING = 0), the last rgba
pills go, and heavy weights (600/700/bold, 60 of them) become 500, the
house pair being 400/500; a guard keeps templates there.

Milestone 465 "Swarm task awareness". Fixes three defects from the live MCP
review #4973:
- #5008 "Swarm task history read as live state"
- #5009 "Crash-loop detection is blind to Swarm services"
- #5011 "Swarm task errors are not captured"
Agent and ingest (agent 1.8.0):
- A manager's agent now reports each service's newest tasks: slot, node,
desired and current state, Swarm's Err/Message, exit code and time.
- They are stored in docker_swarm_services.tasks_json (migration
docker_010_swarm_tasks).
Swarm view (pure):
- A task container is "replaced" when Swarm set its task's desired state off
`running`. Without the task on record, a newer or running task in the same
slot decides.
- Replaced containers are no longer replicas or crashes.
- Each service gets, from the task records:
- failures_1h and failures_24h (failed or rejected tasks);
- crash_looping (Settings → Thresholds count);
- last_error, in Swarm's own words.
MCP:
- New findings: swarm_service_crash_looping (critical) and swarm_task_failed
(warning, on a healthy service with a failure in 24h).
- Down and degraded findings name the last task error.
- list_swarm_services carries the failure fields.
- Container rows mark swarm_replaced and give a replaced task no problems.
Web:
- The containers page swarm cards and the Swarm topology page show crash
loops, recent failures and the last task error.
- The dashboard widget flags a crash loop, and its "failed (24h)" count no
longer counts a rolling update's killed task.

Swarm services/nodes are cluster-global (every manager's API returns the same
list), but each manager reports them independently (rows keyed by host_id) and
the Swarm page grouped by reporting manager — so two managers in one cluster
listed every service and node twice.
Group the reporting managers into swarms in the swarm() view (managers sharing
any node_id are the same cluster, via union-find over node-set intersection),
then dedup within each: one service per name and one node per node_id, keeping
the freshest. Render one section per swarm ("reported by N managers · names").
node_id is globally unique so node dedup is always safe; grouping by node
overlap also keeps it correct if two separate swarms are ever monitored.
View-layer only — no schema/agent change. The main per-host container page is
unaffected (those are genuinely distinct per-node tasks).

The page-top chrome was inconsistent: most nested views used the breadcrumb
kicker + page-title pattern, but plugin sub-pages used ad-hoc "← back" links,
~11 pages stacked a breadcrumb AND a redundant ancestor back button, and two
(monitors/edit, hosts/uptime) had a back button but no breadcrumb. The
settings/plugin_detail page stacked all of it at once.
Unify on the breadcrumb-led model:
- settings/_tabs.html: drop the hardcoded "Settings" h1; the breadcrumb
("Settings › …") plus the tab strip is the header.
- settings/plugin_detail: drop the "← Plugins" back button.
- docker container_detail/swarm/disk + snmp/device: replace ad-hoc back links
with the standard crumbs() breadcrumb.
- host_agent, ansible/*, alerts/maintenance: remove redundant ancestor back
buttons (the breadcrumb's parent crumbs already link there); keep lateral
shortcuts (Inventory/Schedules/Browse/Targets/Groups/New).
- monitors/edit, hosts/uptime: add the missing breadcrumb, drop the back link.

Two new read-only sub-pages, linked from the Docker index header only when the
data exists (non-swarm / Docker-less installs aren't offered empty pages):
- /plugins/docker/swarm — services with replica health (running/desired,
colour-coded green/amber/red), Swarm nodes (role/availability/status, leader
badge), and task→node placement with node ids resolved to hostnames. Grouped
by reporting manager host. Empty state explains manager-only collection.
- /plugins/docker/disk — per-host reclaimable space, image/layer/container/
volume/build-cache sizes, stopped-container count, and a per-image table
(size, shared, ref count, reclaimable badge). Notes prune actions are deferred.
