test_disk_usage_persisted opened a second session.begin() after interleaved
SELECTs, which autobegin a transaction → "A transaction is already begun".
Roll back the read transaction before the re-report write. Restores the
integration lane green for the /system/df slice (a840d6f).

Backend for the image/disk panel (milestone 77 #942). Agent gains
collect_disk_usage() — one /system/df call (gated on containers existing, so
Docker-less hosts pay nothing), surfacing reclaimable bytes (image size held by
unreferenced images), layers/containers/volumes/build-cache sizes, and the top
50 images by size. Emitted as sample["docker_disk"]; host_agent ingest tracks
the newest sample's copy and hands it to the docker capability as a 5th arg.
New current-state tables docker_disk_usage (one row/host) + docker_images
(per-host image rows), docker_007 migration; ingest upserts the summary and
replaces the image set per host (stale images pruned). Unit tests for the df
parsing/reclaimable math + build_sample gating; integration test for
persistence + image-set replacement.

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.

Wires the agent's enriched + swarm payloads through the docker.persist_host_
samples capability:
* Swarm topology — persist sample["swarm"] into docker_swarm_services /
docker_swarm_nodes (upsert + prune stale, host-scoped so two managers don't
clobber). Migration docker_005 adds services.placement_json for the
task→node placement the agent now reports.
* Lifecycle events — _derive_events (pure, unit-tested) diffs the newest
snapshot against stored per-container state: start / stop / die (non-zero
exit) / oom / health_change → docker_events rows. Skipped on a host's first
snapshot so the baseline doesn't emit a start per existing container.
* Alerts — record restart_count (always) and is_healthy (1.0/0.0, only when a
HEALTHCHECK exists) alongside cpu/mem, under host-scoped resource names;
METRIC_CATALOG[docker] gains restart_count + is_healthy so they're alertable.
host_agent ingest captures the newest sample's swarm object and threads it to
the capability (now persist_host_docker(session, host, snapshots, swarm=None));
invoked when containers OR swarm are present, under the same SAVEPOINT. Unit
tests cover the event-diff matrix; integration tests cover event derivation
across two snapshots and swarm topology round-trip (incl. placement).

Adds the milestone-77 storage that doesn't fit on the per-container row:
* docker_events — lifecycle (start/stop/die/oom/health_change), to be
derived by diffing consecutive host snapshots; host-scoped, indexed for
timeline lookups (host_id, container_name, at) and retention pruning (at).
* docker_swarm_services / docker_swarm_nodes — manager-reported Swarm
topology (desired-vs-running replicas, node role/availability/status).
Migration docker_004 extends the docker branch (down_revision docker_003);
purely additive, no DROP+recreate. event/mode/role are plain strings (no
CHECK whitelist), matching how docker_containers models status. Integration
guard asserts the three new host-scoped tables exist.

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).

Collapse the three former check types into a single core `Monitor` entity
with one management surface (/monitors), one result table (monitor_results),
and a single scheduled task. Every type can now watch a free-standing custom
destination (optional host_id) — not just a registered Host.
- models: Monitor + MonitorResult replace PingResult/DnsResult; Host loses its
ping/dns facet columns (now Monitor rows linked by host_id).
- checks: monitors/{ping,dns,http}.py pure probes + runner.run_monitor
dispatcher; one monitor_check scheduler with a per-monitor due-filter.
- status: single monitor_status_source replaces the three sources.
- UI: /monitors blueprint (type-aware add/edit/list/widget); host hub shows a
host's linked monitors + "add monitor for this host"; nav + widget registry
+ alert metric catalog rewired. http plugin folded into core and removed.
- migration 0022 merges the http branch, data-migrates host facets +
http_monitors + all three result histories, drops the old tables/columns.
Resolves the per-host ping/dns auto-attach issue (#275): monitors are now
explicit, never auto-added to every host.

create_app is synchronous (returns Quart) and runs its own internal
asyncio.run for settings/migrations. _make_app wrapped it in asyncio.run,
which nested event loops and raised "a coroutine is required" — the other
integration tests already call create_app() directly. This test was added
in an unpushed commit, so CI never exercised it until now.

From a host's edit page, an operator can run a playbook against just that host
via an ephemeral one-host inventory — no need for the host to exist in a source
inventory.
- ansible/sources.py: pure host_inventory_content(host) -> '<name> ansible_host=<addr>'
- executor.start_run: optional inventory_content written to the temp dir and used
as -i (overrides inventory_path); cleaned up with the creds dir
- hosts/routes.py: POST /hosts/<id>/run-playbook (operator) — validates source +
playbook, builds the ephemeral inventory, starts a user-triggered run, redirects
to the live run detail; edit page gets the ansible source list
- hosts/form.html: 'Run Ansible playbook against this host' panel (shown when
editing an existing host and sources exist) — source + playbook + extra-vars/
tags/dry-run (no --limit; single host)
- tests: unit host_inventory_content; integration runs a hosts:all/connection:local
playbook against the ephemeral inventory and asserts inventory_hostname

Global Ansible credentials, applied to every run (manual + alert-triggered):
- core/settings.py: ansible.ssh_private_key / become_password / vault_password
(plaintext at rest, masked in UI — encryption tracked in #580) + host_key_checking
(default off); surfaced via to_ansible_cfg into app.config[ANSIBLE]
- executor.py: pure build_credentials() materializes creds into a 0600 temp dir
(--private-key, --vault-password-file, become via -e @vars-file so the password
never hits argv) cleaned up in finally; pure ansible_env() sets
ANSIBLE_HOST_KEY_CHECKING. build_ansible_command stays param-only
- settings/routes.py + ansible.html: admin-only Credentials section, masked-update
(blank keeps current, explicit Clear checkbox), reload app config on save
- tests: unit (build_credentials per cred + none; ansible_env toggle); integration
vault round-trip (ansible-vault encrypt a vars file, run via executor with the
vault password, assert it decrypted)

Rebuilds the deleted NUT/UPS automation as a general alert action: any metric
can drive a playbook run on transition-to-firing.
- models/alerts.py + migration 0014: AlertRule.ansible_action (JSON, admin-only,
reuses the #546 param shape); AlertEvent.ansible_run_id links a firing event to
the run it triggered
- core/alerts.py: pure alert_extra_vars() injects steward_alert_* context; on
('firing', event) with an action set, schedule _run_ansible_action (deferred
after commit, same pattern as notifications) — fires once per transition,
consecutive_failures_required is the debounce; system-triggered AnsibleRun
- alerts/routes.py: admin-only parse/validate of the action (source must be
configured, playbook must exist); operators keep editing rules, action preserved
- rules_form.html: admin-only 'On firing -> run a playbook' section
- tests: unit for alert_extra_vars; integration drives record_metric to firing
and asserts a system AnsibleRun ran the playbook with the injected var and the
event linked to it

Run form + executor now support optional params, passed as argv (never
shell-interpolated):
- extra_vars: one key=value per line -> repeated -e
- limit -> --limit; tags -> --tags
- dry-run checkbox -> --check --diff
- executor.py: pure build_ansible_command(playbook, inventory, params); start_run
gains an optional params arg (backward-compatible)
- models/ansible.py + migration 0013: nullable params JSON column
- routes.py: create_run parses + validates (extra-var lines need '='), stores
params on the run, passes to the executor
- browse.html run form: Extra vars / Limit / Tags / Dry-run fields
- run_detail.html: shows the params used
- tests/test_ansible_command.py: unit coverage of the builder; integration test
runs a real playbook with extra-var + limit + check and asserts substitution

Foundation for the Ansible automation milestone (#37) — makes the existing
manual playbook runner actually executable and the schema automation-ready.
- pyproject: [ansible] extra (full ansible package, batteries-included, pinned)
- Dockerfile: pip install .[ansible]; add openssh-client for remote runs
- models/ansible.py + migration 0012: AnsibleRun.triggered_by now nullable so
automated (alert/schedule) runs need no human actor
- ansible/routes.py + run_detail.html: show 'Triggered by' (username or 'system')
- CI: integration lane installs .[dev,ansible]; new tests/integration/
test_ansible_foundation.py runs a real connection:local playbook end-to-end,
asserts success+output, and round-trips a NULL-triggered run
No extra-vars/limit/credentials/scheduling here — those are their own #37 tasks.

Single-repo CI now that plugins are bundled in-tree. Three lanes on push to
dev/main, modeled on FabledCurator's canonical ci.yml (minus frontend/Redis):
- lint: ruff check steward/ plugins/ tests/ (no dep install)
- unit: pytest -m 'not integration' — whole current suite (testing=True mocks DB)
- integration: postgres:16-alpine service via socket-discovered bridge IP; a
boot-and-migrate test creates the real app, running core + all bundled-plugin
migrations, then round-trips the DB — guards the folded-in migration graph.
Registers the 'integration' pytest marker; adds tests/integration/test_boot.py.
