Agent offline is an ordinary rule now. The host_agent scheduler records
host_agent/<host>/seconds_since_seen every minute (from last_seen_at, or
registration time for an agent that never reported), replacing the task
that only logged stale agents. The catalog offers the metric, and picking
it on a new rule fills "> 180".
No data: each rule's state tracks its last sample and its usual gap,
smoothed so that an outage counts as at most three gaps. A core task,
alert_silence_check, runs every 60s and marks a rule no_data_since once its
series has had no sample for three usual gaps (at least 5 minutes; an hour
while the cadence is unknown). A never-sampled rule counts from when it
started watching. The mark sits beside the state, so a firing alert that
goes silent stays firing. Each silence records one event and sends one
notification (rule option notify_no_data, default on; muted in maintenance
windows). The next sample clears it with a "data resumed" event and
notification. Creating, changing, disabling or re-enabling a rule restarts
its watch.
Migration 0029 adds the columns and seeds each existing rule's last sample
and gap from its last day of data, so an upgrade does not flag every rule.
Shown on the Alerts page (a NO DATA badge with its start time), in MCP
list_alerts, list_alert_rules and get_host (state "no_data", no_data_since),
in get_overview findings (alert_no_data, or a firing alert marked silent)
and in the weekly report. The rule form has the notify option, and its
metric reference now matches what traefik records and lists host_agent.
Emails say "no data" and carry the event's note.
The metric-catalog guard also reads positional MetricBatch.add arguments.

#5059 "Alert state machine: acknowledgement holds until resolve; N
consecutive OK to resolve; editing, disabling or deleting a rule resets it".
- The state machine is now next_step(), a pure function of one sample. An
acknowledged alert stays acknowledged while breached; before, the next
breaching sample re-fired it. Firing and acknowledged alerts resolve after
consecutive_ok_required OK checks in a row (new rule column, default 1;
rule form, rules list and MCP create/update_alert_rule clear_after_checks).
- Changing what a rule watches (source, resource, metric, operator,
threshold) or disabling it resets its alert to inactive; a firing or
acknowledged one records a resolved event whose new note says why, and
nobody is notified. Web and MCP edits share alerts.service.apply_rule_change.
- Migration 0028: consecutive_ok_required, consecutive_ok_count,
alert_events.note, and metric_value nullable (a reset has no sample).

#5036 "SSO and LDAP: users keep their auth source, no merging into local
accounts, is_active checked, LDAP TLS real and filter escaped".
- users gain auth_source (local/ldap/oidc) and external_id (migration 0027).
A provider account is found by (source, subject) only: the LDAP entry DN
or the OIDC sub. A first sign-in whose username or email another account
holds is refused with a message naming why; a disabled user stays out.
- Local passwords sign in local accounts only.
- LDAP: port 636 is LDAPS, otherwise StartTLS before any bind; the server
certificate is checked against the system CAs or a CA pasted in
Settings -> Auth. The login name is escaped into the filter (RFC 4515),
and an empty password is refused before the directory sees it.
- OIDC: the ID token must carry this sign-in's nonce and the userinfo sub.

First step of milestone 461 (MCP server). A token is the credential an
MCP client presents as `Authorization: Bearer stw_…` to act as its user.
- api_tokens table (0026): sha256 hash only, display prefix, role
ceiling, expiry, revocation, throttled last_used_at.
- steward/core/api_tokens.py: mint, list, revoke, resolve. Resolution
re-reads the user's current role and acts with the lower of that and
the token's ceiling, so demoting or disabling a user weakens or kills
their tokens with nothing to revoke by hand.
- /ai-access/ (sidebar → Automation → AI access): every user manages
their own tokens, can't grant above their own role, sees the token
once. Session-only: a share-link viewer is refused. Create and revoke
are audited.
- Integration tests drive the routes against real Postgres so their
transactions run for real (#884 escaped CI behind a mocked session).
Task #4965 "MCP-1 — Personal API tokens".

Operator saw the `http` plugin -- deleted when ping/dns/http were unified into
the Monitor entity -- still reported as enabled, with no way to clear it.
It was never an orphaned row. `plugin.http` was hardcoded in core DEFAULTS, so
deleting the app_settings row did nothing: the default reasserted it on the
next settings load. That is precisely why no cleanup UI could have fixed it.
Rule 22 says the removed subsystem should have taken its setting with it.
Purged the surviving references -- the DEFAULTS key, "http" in
CAPABILITY_PLUGINS, the stale plugin_manager docstring example, and the
capabilities blurb still advertising HTTP/uptime as a bundled capability --
plus a migration dropping any stored plugin.http row. Untouched: `http` as a
MONITOR TYPE (icmp/tcp/dns/http) everywhere it appears, and http_001_initial,
which is kept deliberately so existing DBs resolve the revision graph.
For the general case, cleanup splits by provenance rather than being uniformly
automatic or uniformly manual:
Bundled plugins ship in the image and version atomically with core, so they
cannot be transiently missing -- a plugin.* default with no bundled directory
is unambiguously a bug. Guarded by a unit test that fails CI, which is the
only part safe to automate.
External plugins live in operator-mounted /data/plugins, where absence is
ambiguous: unmounted volume, failed install, mid-upgrade. Auto-deleting their
config would silently destroy unrecoverable credentials on a transient
condition, so Settings now lists them under "Configured but not installed"
with an explicit, confirmed, audit-logged Remove. The section hides entirely
when empty, and the remove route refuses if the plugin is actually installed.
Orphan detection reads STORED rows, never the DEFAULTS-merged view -- offering
to remove a default-only key would be a lie -- and returns names only, since
plugin config can hold credentials and listing orphans never needs their values.

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).

plugin_metrics had only a PK on id, so every host-detail, full-metrics, and
dashboard-widget load sequentially scanned the entire time-series table — which
grows by (sources × resources × sample cadence), so the host views got slower
over time (operator-reported "blocked/slow" loads). monitor_results was already
indexed, so the uptime aggregation wasn't the bottleneck.
Add two composite indexes matching the hot query shapes:
- (source_module, resource_name, recorded_at) — history range scans, fleet/
widget queries, and the 'host:%' sub-resource prefix.
- (source_module, resource_name, metric_name, recorded_at) — the latest-value-
per-metric group-by/self-join.
Model __table_args__ + core migration 0023. Integration lane validates the
migration via `alembic upgrade head`.

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.

Milestone 72 phase B — Grafana-style drag-resize grid for dashboard widgets:
- DashboardWidget: replace `position` with a 12-col grid placement
(grid_x/grid_y/grid_w/grid_h). Migration 0021 backfills the old position
order into a 3-up grid (4 cols x 4 cells each) and drops position.
- View + share render a static CSS grid from x/y/w/h: fixed cell height
(h * 70px) with the body scrolling, so the arranged layout is what's shown;
collapses to a single column under 820px.
- Edit view: Gridstack.js 12.6.0 (vanilla, CDN, pinned) — drag the title bar
to move, drag a corner/edge to resize; every change autosaves to a new
/d/<id>/edit/layout endpoint. Replaces the SortableJS position reorder.
- add_widget appends at the bottom-left; remove no longer renumbers.
_get_widgets now orders by grid position (drives DOM + mobile fallback order).
Note: Gridstack drag-resize is browser-only, so CI can't exercise it — needs an
operator visual check of the edit experience.

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 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).

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.

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.

Renames the Python package directory, CLI command, env var prefix,
docker-compose service/container/image, Postgres role/db, and all
visible branding. Marketing form is "Fabled Steward".
Clean break from the previous rebrand: drops the fabledscryer→roundtable
import shim in __init__.py and the FABLEDSCRYER_* env var fallback in
config.py and migrations/env.py. Env vars are now STEWARD_* only.
Heads-up for existing deployments:
- Postgres user/db renamed fabledscryer → steward in docker-compose.yml.
Existing volumes need the role/db renamed inside Postgres, or override
POSTGRES_USER/POSTGRES_DB to keep the old names.
- Host-agent systemd unit is now steward-agent.service. Existing agents
keep running under the old name; reinstall to switch.
