The container list and dashboard widget listed each swarm task as its own cryptic
row (svc.1.<taskid>) and could only show tasks on nodes that run a Steward agent.
Make both views service-centric and cluster-complete.
- swarm_view.build_swarm_services(): model-free builder that merges real container
rows (collected local-per-node, so host_id = the node a task runs on) with the
managers' placement (DockerSwarmService.placement_json). Where placement counts
exceed the local rows on a node — i.e. nodes with no agent — it synthesizes
"ghost" replicas so the replica list matches the cluster. Non-swarm containers
pass through grouped by host.
- /rows + rows.html: a Swarm-services panel collapses each service to one block,
every replica a host chip (status + cpu); ghosts render dashed "N · no agent".
Non-swarm/compose containers keep the per-host table below. New Services stat.
- /widget + widget.html: same service collapse with host chips; standalone
containers stay grouped by host.
- Unit tests for the builder (real+ghost merge, full coverage, partial agent-less,
synthesized service, down state).
No migration — node_id, placement_json and swarm-node hostnames are already stored.

The running count was inflated: swarm-aware agents on every manager list
cluster-wide tasks, so the same container (identical container_id) was reported
once per manager and the dashboard widgets summed them. The earlier swarm dedup
only covered the Swarm topology page — the widgets read raw rows.
- _dedup_by_container_id(): collapse rows sharing a non-empty container_id
(globally unique, so only true duplicates merge); first occurrence wins under
the running-first ordering. Applied in both the containers and resources
widgets before counting/limiting. Rows without a container_id (older agents)
are kept as-is.
- Replaced the static "stopped" tally — not actionable — with "failed (24h)":
distinct containers with a die/oom event in the last 24h (DISTINCT so the
managers' duplicate events don't double it), rendered red when non-zero.
- widget.html empty-state now keys off total_count.
- Regression test: same container_id from two managers counts once; id-less rows
all kept.

The container persister upserted current state keyed (host_id, name) but — unlike
the image/swarm/disk persisters — never deleted containers that vanished from the
host's latest listing. Every removed one-shot container (CI job runners, buildkit
builders, codex jobs) left a permanent "stopped" row, so the dashboard counts
ballooned (e.g. 856 stopped) and read as "not dedup'd". It wasn't dedup — it was
a missing reaper.
- ingest.py: after the upsert loop, delete this host's containers whose name is
notin the newest snapshot (the listing is authoritative — event derivation
already treats absence as removal). Mirrors images/swarm/disk. The existing
`if not snapshots: return` keeps swarm/disk-only samples from touching
containers; an empty container snapshot legitimately means none exist.
- widget_resources.html: this widget shows the busiest running containers by CPU.
Replaced the two unlabeled hairline bars with labeled CPU/MEM bars (label · bar ·
% value, warn/crit colors) so it's self-explanatory.
- Regression test: a container present then absent across snapshots is reaped.

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.

Container list now sub-groups each host's containers by compose project (or
swarm service) with a small subheading, preserving the running-first order;
hosts with no such labels render flat as before. The dashboard status widget
links each container to its detail page and surfaces enriched state inline —
health dot (healthy/unhealthy), restart count, and last non-zero exit code for
stopped containers. Completes the #942 UI surface.

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.

New /plugins/docker/container/<host_id>/<name> detail page (v1 quality):
status/health badge, uptime, CPU/mem, restart count, last exit code (+OOM),
net + block I/O (humanised), image/compose/swarm-service/node/ports, a
range-toggled CPU/mem history graph (HTMX fragment reusing the time-range
selector), and a lifecycle timeline rendered from docker_events (glyph+colour
per event kind). Not-found and empty-history/empty-timeline states included.
Container names in the main list and the per-host hub panel now link to it.

First slice of milestone 77 (Docker monitoring depth). Surfaces real per-container
stats beyond basic state, all read-only on the existing push model.
- agent (→1.4.0): collect_docker now inspects each container (health, restart
count, exit code, OOM) and reads net + block I/O from the stats payload; pulls
compose project + swarm service/task/node from container labels. Per-container
inspect+stats calls run over a small bounded ThreadPool so the ~1s-per-stats
blocking doesn't stretch the sample on a busy host.
- schema (docker_003): additive columns on docker_containers — health, exit_code,
oom_killed, compose_project, service_name, task_id, node_id, and BigInteger
net/blk byte counters.
- ingest: persists the enrichment + restart_count (.get keeps older agents working).
- ui: Docker page rows now show health badge, uptime ("up 3d 4h"), restart count,
exit code (+OOM) for stopped containers, and compose/service grouping label.
- tests: agent helpers (grouping, inspect fields, net/IO sum) + collect_docker
assembly incl. inspect; integration asserts enrichment round-trips.

Docker collection moves off the central single-socket scrape onto the host
agent, giving Docker a real per-host dimension. The Steward host now reports
its own containers like any other host, and same-named containers on different
hosts no longer collide.
- agent: stdlib UDS Docker client (AF_UNIX HTTP/1.1, Connection: close,
chunked-aware), collect_docker() ports the cpu%/mem math; sample["docker"]
added best-effort (silent-skip on absent/unreadable socket). AGENT_VERSION
1.2.0 → 1.3.0; optional docker_socket config key.
- ingest: host_agent ingest hands per-host container snapshots to the docker
plugin via a new "docker.persist_host_samples" capability (no hard import,
no-op when docker disabled), inside a SAVEPOINT so a docker failure never
sinks the host metrics. Resource names are host-scoped ("<host>/<name>").
- schema: docker_containers re-keyed (host_id, name); docker_metrics gains
host_id; docker_002 migration DROP+recreates (dev-only, rule 122).
- ui: Docker page + widgets grouped by host with host links; new per-host
Docker panel embedded on the Hosts hub (gated on docker enabled via a new
enabled_plugins template context). Replaces the SQLite-only strftime
bucketing with DB-agnostic Python bucketing.
- provisioning: install/provision playbooks add steward-agent to the docker
group (best-effort) so the agent can read the socket.
- removed central scrape: docker scheduler.py + scraper.py deleted; plugin.yaml
socket_path/scrape_interval_seconds/include_stopped dropped (plugin 2.0.0).
- tests: agent docker collector units (math, chunked decode, silent-skip,
sample shape, config) + integration (host-scoped schema + persistence).

Run UX: when start_run throws before/around launch (e.g. ENOSPC creating the
temp dir — the box is out of disk), the run was marked "failed" with empty
output. Now the exception is broadcast + written to the run output/results so
the run view shows e.g. "[run error] OSError: [Errno 28] No space left on
device" instead of a blank failure.
Widget audit follow-ups (no broken links were found; these are consistency):
- host_resource_history widget now charts root (/) disk, consistent with the
host panel (was the opaque "disk worst").
- host_resources widget: tooltip on the health dot explaining it warns on the
worst mount while the number shows root.
- status_overview widget detail_url /status → /status/ (avoid redirect).
- Normalize ad-hoc widget empty-states to the shared .empty style (wording,
which distinguishes "configured" vs "data yet", preserved).

The fabledscryer->steward rename had only ever reached host_agent. The other
five bundled plugins (http, snmp, traefik, unifi, docker) still imported
`from fabledscryer.*` (package no longer exists) and read FABLEDSCRYER_* env
vars — so every one of them was broken at import since the original rebrand.
CI stayed green only because none are enabled by default and migrations don't
import plugin modules. Now that they version in-tree, complete the rename:
- fabledscryer.* -> steward.* imports across all five plugins
- FABLEDSCRYER_* -> STEWARD_* in plugin migration env.py files
- author/repository/homepage + user-facing 'Fabled Scryer' strings -> Steward
- snmp/scheduler.py: also drop dead `now`/datetime; record_metric from steward
Adds tests/test_no_legacy_names.py — fails if 'scryer'/'roundtable' ever
reappear in shipped code (the drift bit twice; this stops a third time).
Also clears pre-existing ruff lint debt (unused imports, semicolon statements,
mid-file import) surfaced by the new lint lane.

First-party plugins (host_agent, http, snmp, traefik, unifi, docker) are now
tracked under plugins/ and baked into the image, so they version atomically
with core — ending the cross-repo import drift the roundtable->steward rename
exposed. History for these files is preserved in the archived Roundtable-plugins
repo.
Plugin discovery becomes multi-root: PLUGIN_DIR (single) -> PLUGIN_DIRS
(bundled first, then external) + PLUGIN_INSTALL_DIR. Bundled ships in the image;
third-party plugins still mount at runtime into the external root
(STEWARD_PLUGIN_DIR, default /data/plugins) and downloads/installs land there.
Bundled shadows external on a name collision.
- config.py: load_bootstrap returns plugin_dirs + plugin_install_dir
- app.py: iterate PLUGIN_DIRS at the migration + load sites
- migration_runner.py: discover_all_in() unions every plugin root
- plugin_manager.py: resolve_plugin_path() (pure, first-root-wins); load /
install / hot-reload span all roots; installs target the external root
- settings/routes.py: _discover_plugins scans all roots, dedup bundled-first
- Dockerfile: COPY plugins/ ; docker-compose: drop host bind, document external
- tests/test_plugin_dirs.py: resolution, multi-root discovery, bootstrap split
