MCP-4 of milestone 461 "MCP server: Steward as an LLM-inspectable,
LLM-operable hub". Twelve read-only viewer tools:
- get_overview: what is wrong now, ranked critical-then-oldest. Failing
monitors with their error and when the run of failures began, firing,
pending and still-breaching acknowledged alerts, TLS certificates expiring
within 14 days, agents that stopped reporting, hosts over the configured
CPU/memory/disk thresholds (Settings > Thresholds), failed Ansible runs in
the last 24h, and findings from enabled plugins through a new optional
`mcp_overview(db)` plugin hook. Each finding names the call that shows
its evidence.
- list_hosts, get_host, get_host_metrics
- list_monitors, get_monitor (HTTP header values and URL passwords are
redacted)
- list_alerts, get_alert_history, list_alert_rules, list_maintenance_windows
- query_metrics: the whole metric store, narrowed one argument at a time
(sources > resources > latest values > a series summary)
- list_audit_events
Shared shaping in steward/mcp/tools/_shape.py: UTC ISO times with age_s,
bounded lists that say when and how they were cut, series as
min/avg/max/p95/last plus a ≤60-point series, lookup by id or
case-insensitive name with a did-you-mean, and a range argument that
refuses an unknown key instead of reading it as 24h.
New core reads in steward/core/metric_series.py (sources and resources
via loose index scans, latest values via DISTINCT ON, series across the
raw/hourly-rollup seam). monitors/service.py gains monitor_states,
down_since and recent_failures; agent_overview_by_host now carries the
fullest disk and the last sample time.

MCP-3 of milestone 461 "MCP server: Steward as an LLM-inspectable,
LLM-operable hub". The /mcp tools run outside Quart's request pipeline, so
the queries they share with the pages now live in plain functions that take
an open session:
- steward/hosts/service.py: uptime, status, monitors, agent metrics,
agent overview (stale threshold passed in, not read from current_app),
CPU sparks.
- plugins/docker/service.py: bucket, container_history, host_map,
list_containers, container_events, query_logs.
- steward/alerts/service.py: active_alerts (also used by core/reports),
list_rules, list_maintenance_windows.
- steward/monitors/service.py: monitor_rows (was routes._rows_data).
Routes are repointed and render the same data. One behavior fix rides
along: the container-log search now escapes % and _ so they match
literally instead of acting as LIKE wildcards.

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 C — bring the host-view graphs onto the dashboard:
- host_resource_history widget reworked into a real host-view chart: epoch-ms
linear axis (no Chart.js date adapter), themed like the host-detail charts,
maintainAspectRatio:false so it fills the resized panel, unique canvas per
widget instance (wid), and empty states ("pick a host" / "no metrics yet").
Was previously unusable — it had a broken time axis and no way to choose a host.
- Add a "host" param type: the edit form renders a live dropdown of hosts
(dashboard routes now pass the host list to the editor); the chosen host_id is
stored in config and fed to the widget.
- Hosts-overview widget gains a per-row CPU sparkline (last hour) via the shared
sparkline_svg helper — the host-view at-a-glance trend, on the main widget.
Charts/sparklines render only in the browser, so CI can't exercise them — needs
an operator visual check.

- Host agent panel (reporting state) gains a "Re-provision" collapsible (admin +
linked target + managed key): bootstrap user/password → provision.yml, which
reinstalls the steward account + managed key + agent. This is the missing path
after regenerating the managed key — Update alone can't fix a broken key.
- Remove the Ansible sections (run-playbook + target link) from the host EDIT
page — they were the stale free-text version and the wrong place. They live on
the host detail hub (dropdown + discovered variables). Edit page now links to
the host page; edit_host route simplified (no ansible fetch).

Bring the dashboard in line with the unified host IA + improved displays.
- New core "Hosts — Overview" widget (/hosts/overview/widget): one row per host
combining monitor status (ping dot + latency, uptime 24h) with the agent
glance (CPU / memory / disk root + stale flag), each row linking to the host
hub. Reads agent data from the generic PluginMetric table via a core-safe
_agent_overview_by_host helper (no host_agent import); freshness vs the
plugin's stale window. The granular Ping/DNS/Uptime/Agent widgets stay.
- Group the add-widget picker into Core monitors / Monitoring capabilities /
Integrations (a `group` field on every WIDGET_REGISTRY entry + section
headings in _edit_panels.html), matching the Settings → Plugins taxonomy.
- Fix the agent fleet widget rows to link to the host hub (/hosts/<id>) instead
of the old /plugins/host_agent/<id>/ page.
Scribe #903.

Stop making operators type playbook paths and guess extra-var names.
- Reusable infra: shared ansible/_playbook_vars.html (the discovered-variable
fields) + ansible/_playbook_options.html; two HTMX endpoints —
/ansible/playbook-options (a source's playbooks, optional ?selected for edit)
and /ansible/playbook-vars (a playbook's vars:/vars_prompt: as fill-in
fields). browse _run_form.html refactored to include the shared partial.
- Host "Run a playbook against this host": source dropdown → playbook dropdown
→ variable fields, all chained via HTMX. Handler reuses _parse_run_params so
var__/secret__ fields flow through extra_vars_map + the unpersisted
secret_vars channel.
- Schedules: playbook free-text+datalist → source-dependent dropdown; fixed the
extra-vars edit pre-fill to read extra_vars_map (stale list key after the
earlier JSON-extra-vars change).
Scribe #895.

- Hosts list: new Agent column (latest CPU/mem read from the generic
PluginMetric table — no host_agent import) + an admin "Agent fleet" button.
- /plugins/host_agent/ (old fleet page) now redirects to /hosts/ (folded into
the hub; kept as a redirect so widgets/links don't 404).
- Agent management moved off the "settings" URL: the management page is now
/plugins/host_agent/fleet/ ("Agent fleet" — bulk provision/install/update +
registrations + curl install), reachable from the Hosts list. Old
/plugins/host_agent/settings/ redirects there. Per-host management lives on
the host detail page; this page is now explicitly the bulk/fleet view.
Milestone 70 phases 2-3. Phase 4 (plugins capability/integration split + nav
cleanup) next.

Make Hosts the front-and-center hub. A host now has a real detail page at
/hosts/<id> that pulls its facets into one view, instead of management being
scattered across a nav-less Host-Agents area and the edit form.
- hosts: new GET /hosts/<id> detail route + hosts/detail.html. Shows the
monitors summary (ping/DNS status + latency + uptime 24h/7d/30d), an Ansible
section (linked target, link/create, run-playbook), and an embedded Agent
panel. Hosts list name links here; ansible-link redirects here.
- host_agent: GET /plugins/host_agent/panel/<host_id> — a self-contained HTMX
fragment embedded into the core hub across the plugin boundary (core never
imports plugin models). Shows live agent metrics + Update/Rotate/Remove when
installed, or the provisioning path when not: inline "generate managed key"
warning, a prompt to link an Ansible target first, then Provision (bootstrap
password) / Install (managed key) tied to the host's target scope.
Part of milestone 70 (Hosts hub). Phase 2+ will enrich the list, redirect the
old fleet/settings pages, and re-taxonomize plugins into capabilities vs
integrations.

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

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.
