- New installs start from widgets.RECOMMENDED, packed row by row for the
enabled plugins; the edit drawer can reset a dashboard to it.
- Host Agent — Resources folds into Hosts — Overview (which gains load 1m),
UniFi — Devices into UniFi — Overview; migration 0032 moves existing
dashboards onto the survivors.
- The Overview labels what it counts (hosts, monitors up/down/pending,
alerts firing) and lists firing alerts and down monitors with since-times.
- Uptime polls every 5 minutes (poll_seconds) instead of every cycle.

The dashboard's host widgets took 18-60 s. Every "latest reading" query
(hosts overview, host-agent fleet, host page, vitals, SNMP, MCP get_host)
searched plugin_metrics for the newest row per metric. Postgres has no skip
scan, so each one read every raw sample in the 7-day window.
- plugin_metric_latest: one row per (source, resource, metric).
record_metrics upserts it in the same transaction, moving forward only and
in sorted key order. Migration 0030 seeds it by stepping the existing index.
- Retention drops a latest row once its sample leaves the raw window, so a
resource that stopped reporting disappears when its history does, as before.
Renames carry it along.
- A quiet host keeps its last values, marked stale. A time-bounded query
would have shown it as missing.
- Vitals sparklines span the 6 h they claim, averaged in SQL to ~120 points,
instead of fetching 6 h raw and drawing the last 120 samples.
- Dashboard and share-view cells: "Loading…" until the first answer; a 20 s
deadline per fetch; "Couldn't load (why)" with Retry now and an automatic
retry for cells that don't poll; "as of HH:MM" in the header, and
"couldn't refresh · as of" when a refresh fails over shown data.

- One run per host: start_run claims every host it touches (addresses read
from the inventory Steward wrote; a source's own inventory file is claimed
as that file) before it takes a run slot. The claim is all-or-nothing. A run
waiting on a host shows queued and names the run it waits for, honours a
cancel, and fails after HOST_WAIT_SECONDS (1 h) with which host and run.
- A due schedule whose previous run is still queued or running skips the
firing: last_run_at moves on, last_run_id still names the run going, and
last_error says "Skipped: the previous run was still going". The Schedules
page shows that beside the run (muted), and a launch error in red.
- An alert rule that fires while the action run from an earlier firing is
still going starts no new run; the event says so and names the run. An
in-process set closes the gap between the check and the run being linked.
- docs/core/ansible.md: queued/cancelled statuses and the overlap rules.
Tests: tests/core/test_ansible_overlap.py (claim keys, waiting, all-or-nothing,
cancel, deadline) and tests/integration/test_ansible_overlap.py (two real
runs on one host take turns; schedule skip then fire; alert action skip then
start).

- git ships in the image; checkouts live under /data/ansible/sources
(STEWARD_ANSIBLE_SOURCE_DIR), on the persistent volume.
- One task, ansible_git_pulls, reads the sources every 30 s and pulls each
as its interval passes: a source added in Settings is pulled without a
restart, a removed one is forgotten.
- git_pull: a 120 s timeout ending the process group, GIT_TERMINAL_PROMPT=0,
pull --ff-only, a failed clone removed; it raises GitPullError with git's
message, so the Sync button stops saying Synced after a failure (and the
message is now escaped).
- An alert action's vars and the firing's steward_alert_* vars reach
ansible-playbook as one JSON extra-vars file, not -e key=value, which
Ansible split on whitespace (a rule named 'High CPU on web').

MCP-8 #4972 "Connect card, docs, and end-to-end integration test".
- AI access page: a "Connect a client" card with the /mcp URL (from
Settings → General → Public base URL, else the request host) and recipes
for Claude Code, Claude Desktop (mcp-remote) and other Streamable HTTP
clients, plus the reverse-proxy note. The token-created page shows the
same recipes with the new token filled in, ready to paste.
- docs/core/mcp.md: connecting, the reverse-proxy requirements, the
security model (token ceiling, default deny, check-mode default, secrets,
audit), tools by role, response conventions, adding tools.
docs/architecture.md describes the /mcp dispatch outside the blueprint
pipeline; docs/reference/code-map.md gains an MCP section.
- tests/integration/test_mcp.py: over HTTP, a viewer token lists no write
tools and is refused one by name; an operator token reads get_overview
and its maintenance-window create/end land in the audit log as
"<user> via MCP" with the token id. (Revoked → 401 was already covered.)

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.

Second step of milestone 461. An MCP client (Claude Code, Claude Desktop
via mcp-remote, Open WebUI) connects to /mcp with a personal API token.
- mcp>=2.2 (SDK v2 MCPServer). Mounted by wrapping app.asgi_app, so /mcp
never enters Quart's pipeline; stateless streamable HTTP so a redeploy
never strands a client on a session id the new process didn't issue.
- Auth: Authorization: Bearer stw_… resolves to a Caller (user +
effective role) in a ContextVar; 401 with WWW-Authenticate otherwise.
The web pipeline's database gate runs first, so a DB restart answers
503 instead of failing inside a tool.
- Registry, default-deny: register_tool(fn, role=, read_only=) is the only
door; role and read_only are required. Tools above the caller's role,
or from a disabled plugin, are neither listed nor callable. Undeclared
arguments are refused (not silently dropped); a tool's ValueError
reaches the agent as its reason; a DB failure mid-tool says so.
- Plugins contribute tools via an optional register_mcp_tools(register)
export, all-or-nothing, replaced on hot-reload. Documented in
docs/plugins/writing-a-plugin.md.
- First tool: whoami.
- Tests drive app.asgi_app directly (Quart's test client never reaches
/mcp); the integration test mints a real token against Postgres and
runs initialize → tools/list → whoami → revoke → 401.
Task #4966 "MCP-2 — /mcp transport".

Design-spec updates for m79: the docker_logs_enabled / docker_log_exclude config
keys, the collect_docker_logs collector + the drop-logs-on-backoff note in the
agent internals, and a wire-format design point on docker_logs riding in the same
push (with server-side toggle/exclude enforcement + the per-container ring).
The end-to-end chain (store → rotate → query + ingest enforcement) is already
covered by the integration tests added across steps 2–5, so no capstone test is
added. AGENT_VERSION bump (1.7.0) landed in step 1.

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.
Bundled playbooks tagged: docker_prune → category maintenance + confirm true;
provision/install/update → category host-agent.
Docs: docs/reference/playbook-authoring.md updated (keys now implemented) and a
quick reference added next to the code at steward/ansible/PLAYBOOK_CONVENTIONS.md.
Tests added for category/confirm/alias parsing.

A self-contained guide (docs/reference/playbook-authoring.md) to the contract
between a playbook and Steward's run UI — the `# description:` comment,
vars/vars_prompt → fill-in fields, secret naming, hosts: all targeting,
managed credentials, and idempotency. Includes a "what Steward reads" summary
table, the metadata/extensibility note (only `# description:` today; reserved
`# steward:<key>:` namespace for future keys), and an annotated example.
Meant to be fed to another session authoring Steward-friendly playbooks.

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.

Records the mid-execution pivot: test harness uses testing=True which
mocks the DB, so plugin tests stick to pure-Python unit tests (agent +
metric expander). Server routes are verified manually.

Design for a push-based Python agent that collects CPU/memory/storage/
load/uptime from remote Linux hosts and POSTs to a new host_agent
plugin. Uses per-host bearer tokens, systemd install via curl|sh,
in-memory ring buffer with exponential backoff, and writes to the
existing PluginMetric bus plus a plugin-private registrations table.
No core schema changes — plugin stays strictly isolated.

The UPS plugin's default driver was snmp-ups, so NUT was just translating
network SNMP back into its own protocol — no value over polling the UPS
directly through the existing snmp plugin. The managed-NUT entrypoint path
also broke container startup when config was incomplete.
Deletes nut_setup.py, the NUT block from entrypoint.sh, NUT packages from
the Dockerfile, the ups entry from the plugin catalog example, and the
ups wiring in alerts METRIC_CATALOG, widgets, settings routes, and the
rules form. The plugins/ups source tree (untracked) is also removed from
the working copy. Existing ups_* DB tables are orphaned but harmless in
dev; a drop migration isn't needed.
Follow-up: rebuild "on battery → Ansible shutdown" automation on top of
the alerts system as a new action type that runs a playbook.

Sweeps README, docs/, example configs, code docstrings, report and
notification subject lines, plugin catalog URL default, and stray
comments in Dockerfile/entrypoint.sh/.gitignore. Adds a legacy note
to docs/core/configuration.md explaining the FABLEDSCRYER_* fallback.
docker-compose DB credentials intentionally left as fabledscryer to
preserve the existing pgdata volume.
- Replace up/down arrow reorder buttons on dashboard edit page with
SortableJS drag handles; add POST /d/<id>/edit/reorder endpoint
accepting ordered widget ID array
- Add {% block extra_scripts %} hook to base.html for page-specific JS
- Add dynamic alert rule field loading via HTMX partial (_rule_fields)
so metric/threshold fields update when source is changed
- Add docs/plugins/index.yaml.example showing catalog index format
