The widget-dedup test imported plugins.docker.routes, which re-imports
plugins.docker.models after the app already loaded the docker plugin —
"Table 'docker_containers' is already defined". Same plugin-loader gotcha the
host_agent query helpers avoid.
Extract dedup_by_container_id into plugins/docker/dedup.py (imports no ORM
models, so it's safe to import in either environment); routes.py imports it
from there and the test targets the model-free module.

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.

SNMP devices are config-defined by IP/hostname, not Steward Host records, so
they had no presence on a host's page. Map them by address and embed a fragment
(mirrors the Docker per-host fragment).
- _devices_for_host(devices_cfg, address, name): case-insensitive match of a
device's configured host to the Steward host's address or name (tolerates
non-dict / host-less entries).
- Route /plugins/snmp/host/<id>: renders the matched device(s) + latest readings,
or nothing when none map (so hosts without SNMP carry no empty card).
- snmp/host_panel.html: per-device card (name · address · reachability) with a
readings grid (K/M scaling) and a History link to the full device page.
- hosts/detail.html embeds it after the Docker fragment, gated on snmp enabled.
- Unit test for the matching helper (by address, by name, no-match, blank).

plugin_metrics grows by (sources × resources × ~30s cadence); keeping 90d of raw
is a large table. Add a raw→hourly rollup (mirroring the Docker plugin) so only a
short raw window is kept at full resolution, with hourly averages archived longer.
- PluginMetricHourly model + core migration 0024 (plugin_metrics_hourly: avg/max/
count per source/resource/metric/hour, unique bucket constraint + lookup index).
- steward/core/metrics_retention.rollup_plugin_metrics: date_trunc('hour') agg of
raw older than the hour-aligned raw window, idempotent pg upsert into hourly,
delete the rolled raw, prune hourly beyond the rollup window.
- cleanup.py: plugin_metrics is no longer blanket-deleted at data.retention_days;
_run_metrics_retention drives the rollup with windows read live from settings.
- Settings: metrics.retention.raw_days (7) + rollup_days (90), tunable on the
Thresholds & Retention page (new "Host metrics retention" card).
- Chart read: _history_for_host merges the hourly rollup (older part of the range)
with raw date_bin (recent part, capped ≤1h), so 30d charts keep working —
recent at full resolution, older at hourly. Route passes raw_days from settings.
- Tests: unit (cutoff helpers) + integration (rollup aggregates/prunes; history
merges hourly + raw) against Postgres.
Speed was already handled by the indexes + SQL aggregation; this is the storage
lever (raw window ~10x smaller).

The full-metrics page rendered once server-side with the history query inline,
so the charts blocked first paint and nothing refreshed without a reload (it
reads the latest snapshot the server holds — the agent pushes ~every 30s).
Split it into a shell + two HTMX fragments:
- Shell (host_detail.html): header + shared time-range toggle + two containers;
paints instantly.
- Current state (/<id>/metrics → _host_metrics.html): identity + gauges +
per-core + filesystems + interfaces/disks + temps, from the DISTINCT ON latest
query. hx-trigger "load, every 15s" → live numbers at ~the agent cadence.
- History charts (/<id>/charts → _host_charts.html): the 3 charts + Chart.js,
from the date_bin history query. hx-trigger "load, every 60s, rangeChange" so
they lazy-load (never block paint), refresh slowly, and follow the range
selector. Leak-safe: previous Chart instances are destroyed before re-render.
- Range toggle switched from full-reload links to the shared _time_range.html
(setTimeRange + rangeChange), so only the fragments refetch.
- routes: host_detail (shell) + host_detail_metrics + host_detail_charts, with a
_split_host_metrics helper.
- tests/test_templates_parse.py now also parses plugin templates (these
fragments aren't rendered in the unit lane).

The previous commit's integration test failed at collection-time import:
importing plugins.host_agent.routes (which imports the host_agent ORM models at
top level) double-registers host_agent_registrations against the app-loaded
plugin's metadata ("Table already defined").
Move the two pure read helpers (_latest_metrics_for_host, _history_for_host)
plus SOURCE_MODULE / HISTORY_METRICS into plugins/host_agent/metrics_query.py,
which imports only the core PluginMetric model — no plugin models. routes.py
imports them back. The integration test now imports from metrics_query and no
longer trips the loader's registration guard. No behavior change.

Follow-on to the plugin_metrics indexes. plugin_metrics is already retention-
bounded (core cleanup prunes > data.retention_days, default 90d) and charts top
out at 30d, so the cost wasn't growth — it was the read path shipping raw rows
to Python.
- _history_for_host: bucket + average in SQL via date_bin (epoch-aligned, ~120
buckets) instead of fetching every raw sample (a 30d range was hundreds of
thousands of rows) and downsampling in Python. Uses the new
(source_module, resource_name, recorded_at) index.
- _latest_metrics_for_host: DISTINCT ON (resource_name, metric_name) ORDER BY
recorded_at DESC — newest row per group in one index-ordered pass, replacing
the GROUP-BY-max subquery self-joined back to the whole history.
- Integration test validates both against Postgres.
Deliberately not a materialized raw→hourly rollup: these query-side changes
deliver the speed; a rollup would additionally cut storage and remains a future
option if scale demands it.

docker_metrics.mem_usage_bytes and docker_containers.mem_usage_bytes /
mem_limit_bytes were int4 (max 2,147,483,647). A container using >2.1 GB of RAM
(e.g. 8.18 GB) overflowed the column, so asyncpg raised "value out of int32
range" and the entire docker ingest batch failed — no metrics stored for any
host with a large container.
The I/O counters and the milestone-77 rollup/disk tables already used
BigInteger; this trio (docker_001-era) was missed.
- models.py: DockerMetric.mem_usage_bytes, DockerContainer.mem_usage_bytes,
DockerContainer.mem_limit_bytes → BigInteger.
- migration docker_008_bigint_mem: ALTER COLUMN ... TYPE BIGINT (safe in-place
int4→int8 promotion).

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).

The flat top bar was a set of ungrouped peers and gave plugin data no home.
Move to a persistent left sidebar with grouped sections, per the navigation
redesign (operator-chosen shell).
- base.html: top <nav> → left <aside class="sidebar"> + content column.
Groups: Overview (Dashboard, Status), Infrastructure (Hosts; plugin links
arrive in slice 2), Monitoring (Monitors, Alerts), Automation (Ansible),
Admin (Settings, Audit; admin-only). Brand on top, user/logout at the bottom.
- Active link highlighted by request.path prefix (aria-current).
- Responsive: sidebar slides off-canvas under 900px via a ☰ toggle + scrim
(inline class toggle, no new JS deps). Candle-glow preserved.
- Logged-out pages (login/setup) render without the sidebar (gated on
session.user_id), content area full-width and centered as before.
- Add tests/test_templates_parse.py: syntax-parses every steward template so a
broken tag fails the unit lane (only the login page renders there today).
Plugin nav links (Docker/SNMP/UniFi/Traefik) come next in slice 2 via a get_nav
hook. UI-only; no behavior/route changes.

Follow-up to the incident where an unwritable /data made Steward silently mint a
fresh ephemeral secret key on every boot, orphaning all encrypted secrets — only
discovered when an Ansible run failed. Make both failure modes loud and visible.
- config._resolve_secret_key: if a new key must be generated but can't be
persisted (no STEWARD_SECRET_KEY, unwritable /data), raise RuntimeError and
refuse to start, with an actionable fix (set STEWARD_SECRET_KEY, or make /data
writable by uid 1000). Also raises a clear error if an existing key file can't
be read. First-run on a writable volume still generates + persists normally.
- core.settings: detect secrets stored as ciphertext that won't decrypt with the
current key (scan_undecryptable_secrets at startup; _is_undecryptable helper).
Cached in memory; set_setting discards a key on a fresh write so the banner
clears without a restart.
- app.py: run the scan after migrate_plaintext_secrets, log a warning, and inject
undecryptable_secrets into the template context.
- base.html: admin banner naming which secrets to re-enter, each linked to its
settings tab.
- compose.deploy.yml: document the uid-1000 /data write requirement and the
STEWARD_SECRET_KEY option for multi-node Swarm.

when unpersistable) and the undecryptable-secret detection helper.

The SNMP plugin ships in the image but logged "pysnmp not installed — SNMP
polling disabled" on every poll, so polling never worked. Two coupled defects:
1. The Dockerfile installed only `.[ansible]`, so the `snmp` extra (pysnmp)
was never bundled even though the plugin is first-party and shipped.
2. poller.py used the synchronous pysnmp HLAPI (`next(getCmd(...))`), which
pysnmp-lextudio 6.x removed — it's asyncio-only now — so even with the dep
present, polling would have thrown and silently returned nothing. The 5.x
line that still has the sync API isn't safe on the image's Python 3.13.
Fix:
- Dockerfile: install `.[ansible,snmp]`.
- poller.py: `poll_device_sync` → `async def poll_device` on the asyncio HLAPI,
with a dual-version import (pysnmp 7.x `pysnmp.hlapi.v3arch.asyncio`/`get_cmd`
+ async `UdpTransportTarget.create`; pysnmp-lextudio 6.2.x
`pysnmp.hlapi.asyncio`/`getCmd` + direct `UdpTransportTarget`) so a dependency
bump can't silently re-break it.
- scheduler.py: await poll_device directly; drop the run_in_executor wrapper
and the now-unused asyncio import.
- Add tests/plugins/snmp/test_poller.py covering the version→mpModel mapping,
that the poller is a coroutine, and the graceful no-pysnmp path.
Note: CI confirms import/load and the no-pysnmp path, but has no SNMP target —
live polling against real devices is verified after deploy.

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.

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 collect_swarm(socket_path) to the host agent. Self-detects a Swarm
manager via /info (Swarm.ControlAvailable) — workers and non-swarm daemons
return None and never touch the manager-only endpoints (one cheap /info call,
no 503s). On a manager it queries /services, /tasks, /nodes and emits
sample["swarm"] = {services, nodes}:
* services roll desired-vs-running replicas up from the task list (replica
health isn't on the service object), handle replicated + global mode, strip
the @sha256 image digest, and carry cross-node task→node placement.
* nodes normalise role / availability / status + the manager leader flag.
build_sample omits the swarm key entirely off managers, same silent contract
as collect_docker. Unit tests cover manager detection, replica roll-up +
placement (replicated & global), node normalisation, worker silent-skip, and
build_sample wiring.

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).

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.

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.

Extend the playbook metadata convention with a namespaced `# steward:<key>:`
comment block:
- steward:category — free-text grouping label, shown as a badge in the browse
list and on the run form.
- steward:confirm — true/yes/1/on marks a playbook destructive; the run form
then requires a confirmation tick (required checkbox in the shared vars
fragment) before it can launch.
sources.discover_playbook_meta() parses description + category + confirm (first
match per key; `# description:` still primary, `# steward:description:` alias).
discover_playbook_description() now delegates to it. The browse list reads
per-playbook meta to show category badges + descriptions; the run-form and
playbook-vars fragments render the badge + confirm gate.

LIST, vars under _meta) — valid only as an executable inventory script's
stdout. We were writing it to a static file and passing -i, so Ansible's yaml
plugin rejected it ("Invalid 'hosts' entry for 'all' group, requires a
dictionary, found ...list...") and fell back to implicit localhost → "no hosts
matched". Affected every steward:* scope run; surfaced on the first real
provision.
- New inventory_to_yaml(inv): convert the --list dict → a valid static YAML
inventory (all.hosts dict keyed by host, groups under all.children, group
vars preserved, injected per-host vars like steward_token retained).
- Wire it into runner.trigger_run, host_agent deploy + provision.
- executor writes the file as inventory.yml so the yaml plugin's extension
check reliably claims it.
- generate_inventory unchanged (still the --list dict); conversion happens at
write time. Unit tests added.
Scribe issue #885.

When you click Run, Steward now parses the playbook and renders a field
for each declared variable instead of a blank extra-vars textarea. The
form loads on demand via HTMX (/ansible/run-form/<source>/<playbook>).
- sources.discover_playbook_variables: parse vars: defaults + vars_prompt:
(vars_prompt wins on name collision; non-scalar vars skipped; role/include
vars not traversed). Flags secret-looking names + vars_prompt private.
- Run-time values flow through a JSON extra-vars file (-e @file), which is
space/quote-safe — fixes a latent shlex-split bug in the old -e key=value
textarea path. executor.build_extra_vars_file (pure) + start_run merge.
- Secret-flagged fields are masked AND routed through an unpersisted
secret_vars channel (runner.trigger_run → start_run), so passwords entered
at run time never land in the DB / run history.
- Defaults shown as placeholders (not prefilled): an untouched field falls
through to the inventory/play default instead of overriding it.
- routes: run_form HTMX endpoint; _parse_run_params now returns
(params, secret_vars, err) and reads var__/secret__ fields. Schedules drop
secret vars (can't prompt unattended).
- templates: ansible/_run_form.html fragment; browse.html rewired to HTMX,
static JS run-form removed. Advanced section keeps limit/tags/check + a
free-form extra-vars escape hatch.
- tests: test_playbook_variables.py (discovery + extra-vars file).

Turn the agent-install playbook into a full provisioning + maintenance
path. Solves the bootstrap chicken-and-egg: first contact uses an
operator-supplied password (one run, never stored), which creates a
dedicated `steward` login account with NOPASSWD sudo + Steward's managed
public key. Every run thereafter connects as `steward` with the managed
key — fully unattended (scheduled prune, agent updates).
- core/crypto: generate_ssh_keypair() — ed25519, OpenSSH formats.
- settings: ansible.ssh_public_key (non-secret, displayed) + ansible.ssh_user
(default steward); to_ansible_cfg extended.
- settings UI + route: "Generate managed key" (private encrypted, public
shown to copy) + SSH-user field.
- executor: build_bootstrap() writes a 0600 vars file (-e @file) for the
per-run user/password — never argv, never DB, never logged; drops the
managed key when a bootstrap password is given; --user floor from the
global ssh_user when no override.
- runner.trigger_run: pass-through `connection` kwarg, deliberately NOT
persisted on AnsibleRun.params (password stays out of the DB).
- bundled/host_agent/provision.yml: create steward user + authorized_keys
+ /etc/sudoers.d/steward (visudo-validated) + agent install.
- host_agent: /provision route + "Provision a fresh host" card (bootstrap
user/password; injects pubkey + user + token as space-safe JSON hostvars).
- Dockerfile: add sshpass (Ansible shells out to it for password SSH).
- tests: keypair generation + build_bootstrap (secret stays off argv).

Closes#550 (all four):
- Cancellation: track live subprocesses; POST /ansible/runs/<id>/cancel
(operator) SIGTERMs then SIGKILLs after a grace; new 'cancelled' status
(+ migration 0019, ALTER TYPE in autocommit). Queued runs cancel cleanly
before launch. Cancel button on run detail.
- Concurrency: global semaphore (ansible.max_concurrent_runs, default 3,
Settings→Ansible) caps simultaneous runs; excess show 'queued' (new status)
until a slot frees. Semaphore bound lazily per running loop.
- Structured results: parse PLAY RECAP into per-host ok/changed/unreachable/
failed/skipped + capture failed-task lines, stored in new results JSON
column (migration 0020); rendered as a host-summary table on run detail.
Keeps live streaming (no json-callback swap).
- Retention: full output written to a persistent log artifact
(/data/ansible/runs/<id>.log, env-overridable) beyond the 1 MB DB cap and
across restarts; in-memory replay buffer bounded + GC'd after completion;
Download-log route. Boot reconciliation now also sweeps stale 'queued'.
Unit tests for recap parsing + cancel flagging. Status colors updated across
run list / detail / schedules.

Adds create/edit/delete of playbooks from the UI (admin only), so a homelab
user without a git workflow can author automation in-app. A new always-present
writable local source "steward-local" (/data/ansible/playbooks, env-overridable,
created on first save) is editable alongside operator local-dir sources; the
bundled and git sources stay read-only (git is GitOps, clobbered on pull).
sources.py: write_playbook / delete_playbook (traversal-guarded, .yml/.yaml
only) + validate_playbook_yaml (YAML + play-list check) + is_editable_source.
routes.py: /playbooks/new, /edit, /save, /delete (admin). Browse gains a
"New playbook" button and per-playbook + view-page Edit/Delete for editable
sources. Plain textarea editor with save-time YAML validation. Unit tests for
write/delete/guard/validate.
Task #579 — completes milestone #37 (Ansible automation).
Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
Implements #253's framework: a small core capability registry
(steward/core/capabilities.py) where a module/plugin publishes a named,
role-gated action and a consumer discovers it via has_capability() and runs it
via invoke_capability() — no hard import, graceful degradation, permission
propagation (actor role checked against the capability's required_role).
Core publishes "ansible.run_playbook" (operator) wrapping ansible.runner.
trigger_run (extended to accept a caller-built inventory). First consumer: the
host_agent plugin gains "Deploy via Ansible" on its settings page — pick an
inventory target/group and it installs/updates the agent via the bundled
host_agent/install.yml, minting a fresh token per host and injecting it as an
inventory hostvar (turning per-host curl|sh into one run). Exposed role
ordering as middleware.role_meets. Unit tests for the registry + role checks.
Task #253 (milestone #37).

Ships a read-only "steward-builtin" source (steward/ansible/bundled/) that
always appears alongside operator-configured sources, with two playbooks:
- maintenance/docker_prune.yml — docker system prune for swarm/standalone
nodes (safe by default; prune_all_images / prune_volumes extra-vars to
widen). Schedule it against a swarm-node group for recurring cleanup (#869).
- host_agent/install.yml — installs/updates the host agent (mirrors
install.sh: user, agent.py, config, hardened systemd unit), parameterised
with steward_url + steward_token extra-vars.
get_sources() now prepends the builtin source. Tests updated to find the
configured git source by name; added coverage that the bundled playbooks are
discoverable.
Tasks #869 + agent-install (milestone #37).

Adds cron-like recurring runs (the engine the maintenance-automation work
needs). New AnsibleSchedule model + migration 0018; a core ScheduledTask
(ansible_scheduled_runs, 60s) fires due schedules, each creating a
system-triggered AnsibleRun (triggered_by=None). Centralises the
resolve-inventory → create-run → launch flow in ansible/runner.trigger_run,
shared by the manual route (refactored to use it) and the scheduler.
Schedules UI under /ansible/schedules: create/edit/pause/delete/run-now,
with interval presets, scope targeting (all / group / target), extra-vars /
limit / tags / dry-run, and last-run status (resolved via last_run_id) +
next-run. Unit test for the due-check.
Task #549 (milestone #37).

collect_cpu now returns (aggregate, [per_core]) and build_sample takes a
rate-state dict, so the pre-existing tests that asserted the old float
return / no-state signature needed updating. Mocks the new collectors
(temps/psi/net/diskio) for determinism.

Extends the push agent (v1.2.0) with the Netdata-style signals the operator
wants: per-core CPU, per-interface network throughput and per-disk I/O
(rates derived in-agent from monotonic /proc counter deltas, with
counter-reset clamping), hardware temperatures (/sys/class/hwmon),
memory-pressure PSI (/proc/pressure), and cached/buffers memory breakdown.
All stdlib-only.
Server side needs no migration — these land as additional rows in the shared
PluginMetric table via _expand_sample_to_metrics. Per-resource series use a
':' in resource_name (host:net:eth0, host:core0, host:temp:Package) so the
existing fleet widget's ':' filter ignores them; host-level totals/max are
emitted at the bare host resource. New sample keys are optional, so older
agents keep ingesting unchanged.
Unit tests for the new parsers, rate/reset logic, and the expander contract.
Data foundation for the Netdata-style host view (task #867).

Adds a Kuma-style "is everything up?" surface that aggregates heterogeneous
monitor types via a status-source registry (steward/core/status.py): each
type registers an async source(db) -> [StatusEntry]. Core registers ping/DNS;
the http plugin registers its own from setup() so core never imports plugin
tables. Per entry: current up/down, last-30 heartbeat bar, uptime %
(24h/7d/30d), latest latency + response sparkline, and TLS expiry countdown
(HTTP). New /status page (live htmx refresh) + a status_overview dashboard
widget + nav link. Pure-function unit tests for registry + sparkline.
First deliverable of milestone #68 (task #866).

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.

A fresh install enabled zero plugins — settings.py DEFAULTS had no plugin.*
keys, so to_plugins_cfg returned {} and every plugin had to be flipped on
by hand. Seed docker, host_agent, http, snmp as default-on (generic, non-
vendor-specific); traefik and unifi stay opt-in. Stored choices override
the default, so disabling persists.

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.
