Plugin UIs had no nav home (only dashboard widgets / typed URLs). Add an
optional get_nav() plugin export and surface it in the sidebar.
- plugin_manager: _PLUGIN_NAV registry + get_plugin_nav() getter + a tolerant
_collect_plugin_nav() (missing hook = fine; raising/malformed = logged &
skipped; idempotent per plugin so hot-reload re-runs cleanly). Collected in
both the startup load path and the hot-reload path.
- app.py: inject plugin_nav into the template context, filtered to enabled
plugins so a hot-disabled plugin's link can't linger before restart.
- base.html: render plugin links under the Infrastructure group, with the same
request.path active-state treatment as core links.
- docker/snmp/unifi/traefik: each exports get_nav() → its /plugins/<name>/ view.
- Tests: collector behavior (collect, missing hook, reload-replace, malformed
item, raising hook, sorted output).
With docker enabled, "Docker" now appears under Infrastructure → its fleet view.

Bounds Docker time-series growth (the main scaling concern). New
docker_metrics_hourly table + docker_006 migration; a plugin retention module
(docker.run_retention capability) rolls raw docker_metrics older than the raw
window into hourly averages (idempotent upsert), deletes the rolled raw rows,
then prunes stale rollups + lifecycle events. Core cleanup.py drives it each
hourly run via the capability (no plugin-model import), reading the three
retention windows fresh from settings so changes apply without restart (rule 25).
Settings → "Thresholds & Retention" gains a Docker retention card (raw /
rolled-up / events windows, working defaults 7/90/30 days). Unit tests cover the
hour-aligned cutoff/bucketing helpers; integration test exercises the real
rollup-average + prune across both windows.
Milestone 77 task #941.

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).

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
