#5768 "A maintenance cadence: a group's updates and reboots, one host at a
time, on a schedule". A plan names an inventory group, a weekday and time
in a time zone, a window and a reboot policy (only when required by
default). At its slot a run takes the group's hosts in order and gives each
a #5767 maintenance job. The next host starts only when the last is back in
service: its agent is posting and, for a swarm node, the node is active and
every replicated service is at its replicas. A failure stops the run, and
no host is started once the window has passed. A host's latest failure
shows as host_agent/<host>/maintenance_failed, for an ordinary alert rule.
The page is Hosts → Maintenance.

#5767 "Steward hands a host a maintenance job and follows it to the end,
through its own restarts", milestone 514.
A host_maintenance_jobs row per job: queued → updating → [draining →]
rebooting → [undraining →] done, or failed / timed_out. Steward's answer to
an ingest post carries the step that host's agent should carry out now; the
agent (1.18.0) leaves each step id for the root helper once, and the helper
refuses an id it already ran, so repeats are harmless. Results come back as
the #5766 maintenance events, matched by step id; the reboot completes when
the host's `started` event has a boot_at after the reboot was handed out.
The job reboots only when the update says one is needed (or never, if asked).
A swarm node is drained first by itself if it's a manager or by a manager
with the helper, and made active after; with no manager to drain it the job
is refused. A minute tick times out a job past its state's deadline. A
maintenance window over host_agent/<host> lasts the rest of the job.
Everything is on the row, so a Steward restart, or the reboot of the host
Steward runs on, resumes from the next post. Ingest runs it in its own
savepoint so a job going wrong never costs the samples.
The Agent panel leads with a running job and says what a finished one did;
Manage agent has Update now (with "never reboot"), or says why a job can't
start. Integration test: hand off, Steward restarts, the post-boot events
close the job.

#5766 "A root helper the agent can start, for a fixed set of maintenance
actions and nothing else", milestone 514.
The agent runs unprivileged under NoNewPrivileges, so it can't update or
reboot its host. It now leaves a request in /var/lib/steward-agent/requests,
the one path its unit lets it write; steward-maint.path starts maint.py as
root, which reads it without following links, accepts only update, reboot,
drain or undrain, deletes it, and writes the outcome to
/var/lib/steward-maint/results. The agent (1.17.0) reports each new result
state once as a `maintenance` event, re-checks pending updates when an update
finishes, and says in its metadata whether the helper is installed.
The units and the helper are served from one copy at
/plugins/host_agent/files/<name> (a fixed list), and install.sh plus the
install, provision and update playbooks all fetch them, replacing three
inline copies of the unit. Update agent installs the helper on existing
hosts; the Agent panel says under Manage agent whether it is there.
Steward handing out jobs is #5767; the cadence is #5768.

Step 1 of milestone 514 "Updates and reboots on a cadence, carried out by
each host's agent…": #5765 "The agent reports pending updates and whether
a reboot is required".
- Agent 1.16.0: an hourly background check (apt-check, apt list, or dnf -C
with updateinfo and needs-restarting), each command bounded at 120 s, no
root and no network. Debian's reboot-required marker and its packages
are read every sample.
- Ingest records updates_pending, updates_security and reboot_required for
rules, and keeps the newest on the registration (host_agent_005_updates).
- The Agent card leads with "Reboot required since …", then the updates
waiting or "Up to date", with when the check ran. list_agents carries
them too.

#5756 "The agent says when its host rebooted and when it lost contact, so
downtime is recorded as what it was". Agent 1.14.0 posts events with the
next post that gets through: started (with the host's boot time), stopping
(on SIGTERM, with whether systemd says the host is going down) and
lost_contact (from its first unanswered post to the one carrying it).
Steward keeps them as the host's downtime (host_downtime): reboot,
agent_stop, unclean (a boot after the agent was last heard that nobody
announced) or lost_contact. Retried posts apply once.
An announced stop explains the silence for reboot_grace_seconds (Settings
-> Plugins -> host_agent, 10 minutes): seconds_since_seen reads 0 until
then, and the host's other rules go quiet with it (agents_away beside
#5721's registry). Past the grace, agent offline fires.
The host's Agent card lists the last 7 days of downtime. Rows are pruned
at data.retention_days.

Hosts list:
- CPU and Memory are their own labelled columns (#5279); a silent
agent's last readings are greyed, and Status says "agent silent for 7m".
- One uptime figure, 30 days, with 24h and 7d on hover. The SLA tab
(/hosts/uptime) repeated it and is removed (#5280; one home per fact).
- Status is a word with how long ("Down for 12m"); host_status now carries
down_since. Edit and Delete live on the host's page only (#5281).
- Figures are right-aligned with tabular digits (.table .num), not a
monospace face.
Agent fleet (#5282): its add-host form is gone, so hosts are added only on
Hosts -> Add host. That form was also the only way to get a token for a
manual curl install, so that moves to the host's Agent card as "Install
manually" (POST /fleet/<host_id>/register), shown on the fleet page as
before. "Delete" there reads "Unregister".
Add host (#5283): laid out like the add-monitor form; a name clash comes
back inline with what was typed instead of a bare text 400; the address
is optional, as the host page already allowed.

Docker panel (#5276): problems first, then the 8 busiest running
containers by CPU; the other running and the stopped fold behind one
"+N more running · M stopped" line. Containers that are not swarm tasks
read the way the Docker page reads them: CI jobs as "CI: workflow · job",
buildx builders as "BuildKit builder · name".
Monitors card (#5277): the edit/delete icon buttons and the inline add
form are gone. Each row links to its monitor's page; "Add monitor" opens
the add form filed under this host, starting from its address, with the
host in its breadcrumbs and Cancel back to it.
Agent card (#5278): Full metrics stays in view; Update, Rotate token,
Unregister agent (was "Remove") and Re-provision sit under "Manage agent".

#5210 "Problems first, with since-time, across every list" (milestone 477),
second batch.
- Host page: an "Alerts on this host" strip first (rules on its agent
series, its containers or its monitors: alert_svc.watches_host); its
monitors problems first with "Down 12m · reason"; Docker above Ansible.
- Uptime page and widget: worst 24h uptime first, then 7d and 30d; hosts
with no uptime yet last.
- Agent panel and fleet widget: last seen as "3m ago", not a clock time.
- SNMP: a device is "Reachable" only while it answered within the last 3
polls; older readings say "No answer" with their age, and every device
says when it was last read (was: reachable whenever any reading existed).
- Traefik: a router missing from 3 scrapes in a row is listed apart as no
longer reported, by when it was last seen, instead of keeping its last
state (a removed router stayed Failing).

#5099 "A name containing a quote runs script when an admin clicks Delete".
Inline handlers like onclick="return confirm('Delete {{ rule.name }}?')" are
HTML-decoded before the JavaScript is parsed, so autoescaping did not stop a
name such as x');fetch(…);// from running.
- Every prompt (22 handlers, plus the docker prune and token revoke ones)
is now data-confirm="…", read through dataset by one submit listener in
base.html; nothing rendered is parsed as JavaScript.
- The remaining inline handlers take integers only (|int), and the time
range buttons pass this.dataset.range.
- tests/test_inline_handlers.py fails on any {{ }} in an inline handler that
is not |int, with a self-test; tests/_templates.py is the one template
walker the template guards now share.

#5031 "Forged-request protection: SameSite cookie, per-session CSRF token
on every non-GET, HTMX header". A page on another site could make a
logged-in browser POST to Steward with the session cookie attached.
- steward/auth/csrf.py: a per-session token, checked in one before_request
for every POST/PUT/PATCH/DELETE (header X-CSRF-Token or form field
csrf_token, constant-time compare). The bearer-authenticated host-agent
ingest is exempt; /mcp never reaches Quart.
- Every POST form renders {{ csrf_field() }}; base.html carries the token
in a meta tag and adds it to every HTMX request; the dashboard's fetch()
calls send it.
- The session cookie is SameSite=Lax; login issues a fresh token.
- PUBLIC_BASE_URL is now loaded from Settings at startup (it was only set
when Settings → General was saved).
- tests/test_csrf.py: refusal, acceptance, rotation, the ingest exemption,
and a guard that every POST form in the templates carries the field.

Realizes the chosen host-summary layout: a thin live vitals bar at the very top,
separate from the agent management panel (no more duplicated CPU/MEM/DISK/LOAD).
- New fragment _host_vitals.html + route /plugins/host_agent/vitals/<id>: compact
CPU / Memory / Disk(/) / Load-per-core (threshold-coloured + sparkline) +
Pressure + live/stale·version·last-seen. Polled every 15s; renders nothing
until the agent reports.
- The metric computation (latest snapshot + 6h sparkline query + load/core + PSI)
moves from host_panel into host_vitals. host_panel slims to management only
(reg/target/reporting/stale/ansible) and no longer queries metrics; panel.html
drops the gauge row + pressure block, keeping status + lifecycle actions.
- hosts/detail.html: vitals strip on top (full width, live), then a 2-col
[Monitors | Agent] grid, Ansible full width below, docker fragment last.
UI only. Templates parse; plugin-template parse test covers the new fragment.

Move the hardcoded warn/crit cutoffs into Settings -> Thresholds (DB-backed,
live, no restart). New thresholds.* keys + to_thresholds_cfg() + a
threshold_style(value, kind) jinja global that reads them; latency reuses the
existing ping good/warn keys, uptime is direction-aware (floors).
Replace the _macros metric_style/uptime_style macros (now removed) with the
global across Hosts-Overview, host_agent fleet + panel, Uptime/SLA widget, and
the ping page uptime column — all now honor the configured cutoffs. Uptime keeps
its green 'good' look when not degraded.
Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
Milestone 72 phase A (clarity wins, no schema change):
- Add shared metric_style() macro in _macros.html: colours a numeric metric
amber (>=warn) / red (>=crit) on the value ITSELF, not just the status dot.
Defaults 80/90 for percentage gauges; load /core uses warn 80 / crit 100.
Applied to CPU/mem/disk across host_agent panel + fleet widget + the unified
hosts-overview widget.
- Link every host reference to the host hub (/hosts/<id>) in ping, dns,
hosts-overview, host_agent fleet, and uptime widgets; status widget entries
link to their own detail_url. All guarded on session.user_id so the public
share view degrades to plain text (the bare href carries no share token).
- Fix truncation: title= tooltips on all names that ellipsis, plus a hover
underline affordance on the now-clickable ping-name links.

- 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).

- Each at-a-glance metric (CPU, Memory, Disk /, Load) now shows a 6h sparkline
(reused core.status.sparkline_svg + a recent-series query; disk uses the root
mount sub-resource) so trend/consistency is visible, not just the instant.
- Load is now normalized: "Load /core" = 1m load ÷ CPU cores as % (100% = run
queue matches capacity), comparable across different hardware. Cores derived
from the per-core CPU metrics already collected — no agent change. Raw load
in the tooltip.
- Added a "Pressure 10s" line: PSI cpu/mem/io (some, avg10), the
hardware-independent saturation signal already collected by the agent.
Scribe #898.

The "Disk (worst)" number was opaque at a glance. Show the root filesystem (/)
usage instead — what people actually care about — on the host panel and the
dashboard widget. "Worst" is kept only for the widget's health dot (so a full
/var or /data still warns) and on the full-metrics page (per-mount + worst
trend). Added hover tooltips defining CPU / Memory / Disk / Load.

A failed provision looked successful in two ways:
1. The host panel showed the agent as deployed (metrics + Update/Rotate/Remove)
because provision/deploy mint the registration row BEFORE the playbook runs
and the panel keyed "installed" on that row. Now gated on the agent actually
checking in (reg.last_seen_at). Three states: reporting (metrics + lifecycle),
pending (token minted but no check-in → "no metrics yet, deploy may be
running/failed" banner + retry + Clear pending registration), and none
(install path).
2. The run reported success though nothing ran — ansible-playbook exits 0 on
"no hosts matched"/empty inventory. The executor now treats an empty PLAY
RECAP (returncode 0 but no hosts executed) as failed, with a clear failure
note. Non-zero exits and recap failed/unreachable were already caught.
Scribe issue #887.

Dev-only instance, no bookmarks — per family rule 22, fully remove old paths
instead of shimming them.
- Delete the /plugins/host_agent/ (index) and /plugins/host_agent/settings/
redirect routes; delete the now-dead host_list.html fleet template.
- Move the remaining management POST routes off /settings/ to /fleet/
(add-host, rotate-token, delete) — single canonical prefix.
- Repoint real callers to canonical URLs: dashboard widgets (host resources →
/hosts/, history → /plugins/host_agent/fleet/), the full-metrics page
breadcrumb + back link (→ the host hub), Settings→Ansible link, and the
agent panel's curl-install link.

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.
