Measured on dev (385a579), agent posts cut to five samples still dropped:
flush=8.8s for 990 rows, 6.6s for 680, 8.4s for 1000 — about 110 rows/s,
~9 ms a row, with rules and evaluation near zero. One random read per
row fits a random uuid4 primary key whose index no longer fits in memory:
every new row lands on a random page of it. (Inferred from the rate; the
table and index sizes have not been read.)
- steward.core.ids.time_ordered_id: a UUIDv7-layout string (48-bit ms
timestamp, then random), same 36-char shape as the stored uuid4 ids, so
no migration. Python's uuid7() arrives in 3.14; the image runs 3.13.
- Used for plugin_metrics and its hourly rollup, monitor_results,
audit_events, the docker metrics/hourly/events/logs tables, and the
traefik and unifi time series.
- MAX_SAMPLES_PER_INGEST 5 → 2 (~400 rows) for now: it fits the agent's
10 s even at the old rate, so hosts land data whichever way the new rate
comes out. Raise it once the new rate is measured.

The dispatcher ticked once per MONITORS_POLL_INTERVAL and stamped
last_checked_at when the whole batch finished. With a 60 s tick and a 60 s
monitor the next tick saw 59.x s elapsed and skipped, so the monitor ran
every 120 s; a 30 s monitor could never run faster than the tick.
- The dispatcher ticks every 5 s (DISPATCH_TICK_SECONDS) and reads the
monitors and intervals fresh each tick, so a changed interval applies at
the next one.
- Due is measured from the scheduled start, stamped before the check runs,
with half a tick of slack so tick jitter never costs a whole tick. A
long-overdue monitor runs once.
- Each check runs in its own task and records its own result, so a slow
probe holds up nobody; a monitor still being checked is not started
again, and it is freed in a finally.
- A check past CHECK_DEADLINE_SECONDS (120) is recorded down with "Check did
not finish within 120 s" rather than holding its monitor forever.

Traefik: routers are graded from their latest scrape (router_state: crit on
any real 5xx share, warn on p95 past the latency critical cutoff or a high
4xx share). Failing and slow routers lead as cards that say why; healthy
ones fold into one table that stays open or shut across polls. Proxy
counts are stat tiles; certificates are graded by Settings -> Thresholds
(tls_days).
UniFi: WAN health is a stat strip (latency graded by the thresholds),
devices carry status dots, event categories and firewall actions are
badges, the alarm count reuses .count-badge (renamed from .nav-count).
SNMP: each device wears a status badge and its readings are stat tiles.
Agent fleet: the table comes first, with a Status column (Reporting /
Silent / Never reported, by the host page's stale_after_seconds), silent
agents first, hosts linked, last seen as |ago.
Audit: entries name their entity (one query per type, steward/audit/
service.py) and link it; something deleted since keeps the name its entry
recorded and says "(deleted)".
Tokens: charts read colours through chart-colors.js (stewardColor resolves
a token to the rgb the browser computed; Chart.js defaults take the page's
text and border colours), so host, history, Traefik and SNMP charts drop
their hex. Template hex colours reach 0 (HEX_CEILING = 0), the last rgba
pills go, and heavy weights (600/700/bold, 60 of them) become 500, the
house pair being 400/500; a guard keeps templates there.

Runs read "update.yml on web-1" (run_title over the scope label, beside
describe_scope) on the runs list, the run page's title and breadcrumb, and
the run-started panel. The list shows started |ago (full time on hover),
|duration (counting "so far" while a run is going) and a dry-run tag.
Run statuses join STATES, so the list and the run page use status_badge:
queued dim, running info (blue, so work in progress doesn't read as a
problem), success ok "Succeeded", failed crit, interrupted warn, cancelled
dim. run_started.html leaves its hard-coded colours for tokens; the run
page's facts move to the .kv list and its failures to var(--red). Template
hex colours: 54 -> 47.
Also fixes#5124's sidebar count, which CI run 8389 failed on: the stylesheet
guard allows no weight above 500, and .nav-count asked for 600.

The Alerts page's active list now says each alert in one line around the
resource it watches, e.g. "cpu_pct on web-1 is 94% (> 90%), firing for 12m",
with web-1 linking to its host, monitor or container page (or the plugin's
page for Traefik, UniFi and SNMP). Values take their unit from the metric
name through formatting.metric_value. A silent series reads "No cpu_pct from
web-1 for 20m"; an up/down metric says the word.
Actions follow the routes' roles: acknowledge, edit, toggle and New rule for
operators and admins, Delete for admins only, nothing for viewers.
The sidebar shows how many alerts need attention beside Alerts, from an
async context processor that skips htmx fragments, logged-out pages and the
database-down page, and renders without the count if the query fails.

NOW is fixed when the module is imported; by the time the detail page
rendered in CI seven seconds had passed, and |ago rightly said "12m 7s

The Monitors list now opens with a count strip (down, up with how many
degraded, pending, paused) and sorts down, degraded, pending, up, paused,
by name within each. Degraded is up but worth a look: uptime at or below
its warning floor, or the latest response past its critical cutoff, both
from Settings → Thresholds; a slow-but-tolerable reply is coloured, not
sorted.
A monitor had no page of its own: every link went to the list. Now
/monitors/<id> shows its state and since when, latency, uptime for 24h/7d/
30d, TLS days, the last checks, recent failures with their errors, and its
settings (HTTP header names, never their values). Status links to it, and
adding or editing returns to it.
Adding is its own page (/monitors/new, form.html shared with edit) behind
an "Add monitor" button; a refused add re-renders the form with the error
and what was typed instead of a bare 400 text. Row actions are labelled
icon buttons, type names read Ping/TCP/DNS/HTTP (|monitor_type), and the
heartbeat uses pill-up/pill-down, so HEX_CEILING drops to 56.

#5120 "Status page: what is wrong first".
- A "Needs attention" card heads the Status board: each down monitor with
how long it has been down, and each active alert (firing, acknowledged,
pending, no data) with its condition and how long, linking to its history.
- StatusEntry.since / since_at_least: when the current up/down run began,
from the recent checks (streak_start); "for at least" when every check we
have agrees.
- Counts as stat tiles (Down, Active alerts, Pending, Up); names wrap
instead of being cut off; dots carry their label.
- Uptime and TLS are coloured by status_class against Settings → Thresholds
instead of literal cutoffs; heartbeat pills and DOWN/UP use tokens and
status_badge rather than hex and bold.
- tests/core/test_status_page.py: streak_start cases, and the rows render
with the problem card before the list, each since-time, threshold tones
and no hex colour.

#5094 "Status and layout macros, and form classes".
- formatting.STATES: one state -> (tone, label) map for up, down, stale,
firing, pending, acknowledged, no_data, ok, warn, crit, resolved and
inactive; status_info() reads it (an unmapped state is drawn dim under its
own name). required() lets a macro refuse a missing argument.
- _macros.html: status_badge and status_dot (a dot always carries its label,
sr-only unless shown), stat_tile, empty_state, page_header (actions via a
call block) and icon_button, which raises without a label.
- steward.css: tone classes (badge-/dot-/stat- ok, warn, crit, info, dim),
.sr-only, .page-header, .stat-tile, .empty-state, .btn-icon and the form
classes .field, .field-label, .field-hint and .input. Info text is a 40%
mix (--blue): the house --fs-info-fg falls to 4.18:1 on its tint over a
hovered row, 40% holds 5.09:1.
- First users: the Alerts list, history and maintenance pages (headers,
state badges, empty states) and the alert forms' hints; the inline inp/lbl
style sets on the monitor and host forms become .input / .field-label.
- tests/core/test_macros.py renders each macro through the app environment.

#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.

#5093 "Shared format filters and status_class driven by Settings → Thresholds".
- steward/core/formatting.py: human_bytes (binary units), human_rate,
human_duration (two largest units), ago (a <time> titled with the absolute
UTC time) and status_class(value, kind, thresholds) -> ok/warn/crit/unknown,
which raises on a kind the thresholds don't name.
- app.py registers them as the bytes, rate, duration and ago filters and the
status_class global; threshold_style is now graded by status_class (and caps
its weight at 500).
- Replaces the copies: docker's _human_bytes/_human_uptime, core alerts'
_duration, the host-agent fmt_bps/fmt_bytes macros, the Traefik and UniFi
byte-rate arithmetic, the swarm-failures ago macro and two uptime spans.
- Tests: a table per helper, and every template compiled against the app's
filters, so an unknown filter fails CI rather than a page.

#5066 "Alert history page". /alerts/history lists every alert transition
in a range (1h–30d, the shared range picker), newest first, all rules or
one (?rule=). Each row: from → to, the value against the rule's condition
("no data" for a silent one), email and webhook sent or failed with the
error, "muted · <window>" (and "notified when the window ended") taken out
of the event note, other notes, and a link to the Ansible run an action
started. Range and rule changes swap only the rows (HTMX). Viewer role.
The Alerts page links each rule's history and the whole history. The query
moves to alert_svc.history, which MCP get_alert_history now uses too.

The rule name goes into the Subject header, and EmailMessage refuses a
header holding a line break, so the whole email failed. The web form can't
enter one but MCP takes any string. The subject now folds whitespace.

#5064 "Notifications that arrive":
- render_webhook: alert.* is escaped to sit inside a JSON string (a quote
or newline in a rule name no longer breaks the body); raw.* is the plain
value for |tojson; a missing value reads "no data"; the template runs
sandboxed and the body is checked to be JSON before it is sent.
- SMTP: 15s timeout; port 465 connects with implicit TLS, otherwise the
box means STARTTLS; a From address setting (falls back to the username).
- A webhook error no longer carries the URL, which is a secret.
- Settings → Notifications: "Send a test email" / "Send a test webhook"
send a sample alert with the form's values (unsaved) and show the result
and the body that went out; template help names alert.* and raw.*.
- Notification audits go through audit_request; the test send is audited
as settings.notification.tested, with the channel and outcome only.

Notifications and alert actions now start only once the evaluating
transaction commits, and never for one that rolls back. record_metrics
queues them on the session (_after_commit), and after_commit/after_rollback
listeners on the sync session spawn or drop them. Spawned tasks are held in a
module set so they cannot be garbage-collected before they run.
A maintenance window no longer skips evaluation. Alerts in its scope still
change state, but their notifications and actions are held, and each event
says so ("notification muted: maintenance window <name>"; also on no-data
and resume events). notify_after_maintenance, run every minute with the
silence check as the new core task alert_reconcile, sends one notification
for an alert still firing after its window ends and runs its action. The
event's note records the release.
Alert actions go through runner.trigger_run like every other run path, so
the playbook and the inventory must be ones the source lists (#5034 guards).
The firing event links to the run, or its note says why the action did not
start. The maintenance page and form wording now say what a window does.
Tests:
- integration: a rolled-back evaluation notifies nobody, and dispatch waits
for the commit; maintenance mutes while the state moves and notifies once
when the window ends; an action whose playbook is outside its source is
refused, with the note set;
- the alert-action test uses a listed inventory name and waits, with a
deadline, for the run the action starts;
- unit: _muted_by.

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.

#5061 "Metric catalog belongs to what emits: plugins register their
metrics; names match what is recorded".
- The static METRIC_CATALOG is gone. metric_catalog() is core's own sources
(the four monitor types and "steward", the app's open_fds/open_fds_pct,
which were recorded but never offered) plus each loaded plugin's
get_alert_metrics() export. A disabled plugin's sources leave the picker.
- traefik offers what it records: error_rate_4xx_pct and error_rate_5xx_pct.
The old "error_rate" was never recorded, so a rule on it could not fire.
- tests/core/test_metric_catalog.py walks every MetricBatch.add /
record_metric call (traefik's tuple loop included) and fails on a recorded
metric the catalog lacks; it shows on a synthetic writer that it can fail.

#5060 "One evaluation path: record_metrics batch API; host-agent ingest
evaluates rules".
- record_metrics(session, rows) writes metric rows and evaluates the rules
that watch them, reading rules, states and maintenance windows once per
batch. Each rule sees its key's samples oldest first, so an agent catching
up after an outage counts consecutive checks as they happened.
- Host-agent ingest now goes through it. Before, it wrote plugin_metrics
directly and no host_agent rule could ever fire. The catalog gains the
per-mount disk_used_pct ("<host>:<mount>").
- MetricBatch gathers a transaction's samples; the docker ingest, traefik,
unifi, snmp, monitor and self-monitor writers record one batch each instead
of a rule query per sample.

#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).

#5037 "Secrets at rest and in run output: webhook URL and git token
encrypted, askpass via env, secret values scrubbed from logs".
- webhook.url joins SECRET_KEYS; existing values are sealed at startup by
migrate_plaintext_secrets. Settings -> Notifications no longer echoes the
URL: it names the saved host, keeps it when left blank, and has a Remove
box.
- Git source http_token is sealed inside ansible.sources on save and at
startup, opened in get_sources, and counted by the undecryptable-secrets
scan as ansible.sources[<name>].http_token.
- The askpass script holds no token: git runs it with STEWARD_GIT_TOKEN in
its environment and printf prints it as data.
- The executor masks every secret the run is handed (become/vault
passwords, bootstrap passwords, sensitive run vars, and the per-host agent
tokens the host_agent plugin now passes as redact) in each line before it
is broadcast, logged or stored.
- Bundled "Write agent config" tasks are no_log; a test fails if any bundled
task templating steward_token lacks it.

#5034 "Playbook runs: path and inventory checks in trigger_run, connection
vars admin-only, confirm enforced server-side, web actions audited".
Ansible runs inside the Steward container, so an operator who could name
any playbook path, set ansible_connection=local or ProxyCommand ssh args,
or put {{ lookup('pipe', …) }} in a value could run commands on Steward.
- steward/ansible/guards.py: check_playbook (the source must list it),
check_inventory_scope (steward:* or an inventory file the source has),
check_vars_for_role (ansible_* beyond host/port/user/password/become,
and any Jinja in a value, are admin-only), changed_vars (an edit is
held to the role only for what it changes).
- trigger_run applies the path checks, so every run path — web, MCP,
alerts, schedules, plugins — gets them.
- Variables are checked by role on the web run form, host-page runs,
schedule create/update, inventory group/target create/update, and MCP
run_playbook / create_schedule / update_schedule.
- A steward:confirm playbook needs the confirmation ticked on the server
side for a real (non-check) web run, as MCP already required.
- Audited: runs, cancel, schedule create/update/enable/disable/delete/
run-now, playbook create/update/delete, inventory group and target
create/update/delete (variable names only, never values). One
audit_request helper serves the web routes.

on a synthetic broken input (rule: a guard must be able to fail).

#5032 "Plugin install takes its URL and checksum from the catalog, requires
the checksum, and extracts only inside the plugin folder". The install form
carried the download URL and checksum as hidden fields, so any admin POST

member like ../x.py was written wherever it pointed.
- The route takes only the plugin name and reads download_url and
checksum_sha256 from the configured catalogs; a name no repository lists
is refused. Installs are audited (plugin.install / plugin.install_failed).
- The checksum is required; the name must be a plain identifier.
- extract_plugin refuses any member that resolves outside the plugin
folder, caps the download at 50 MB and the unpacked size at 200 MB.
- The zip unpacks into a staging folder and is swapped in whole: a refused
or failed install leaves the installed copy untouched, and an update no
longer leaves the old version's deleted files behind.
- The catalog shows "Can't install: the catalog lists no checksum" in place
of the button for an entry without one.

MCP-7 #4971 "Monitoring-config write tools: monitors, alert rules, acks,

The validation the forms did inline (or not at all) moves to the services,

- alerts/service: METRIC_CATALOG and SOURCE_MODULES, resources_for,
metrics_for, rule_fields (source, resource and metric from the same
choices the rule form offers), add_rule, acknowledge, window_fields.
Tools: create_monitor, update_monitor (config merged over the stored one;
a rename warns about rules still watching the old name),
set_monitor_enabled, create_alert_rule, update_alert_rule,
acknowledge_alert, create_maintenance_window (duration or end),
end_maintenance_window (ends one in progress, cancels an upcoming one) —

The admin banner counts every plugin load failure, but settings/plugins.html
only rendered failure reasons inside the plugin card macro -- which iterates
discovered plugins. A plugin that failed BECAUSE it has no directory was
therefore counted in the banner and shown nowhere on the page the banner links
to. That dead end is what the operator hit: "1 plugin failed to load" on the
dashboard, nothing wrong on the details page, and no way to clean it up.
Folds the reason into the "Configured but not installed" rows rather than
adding a competing section, and drives that list from the UNION of stored
plugin.* settings and recorded load failures instead of stored settings alone.
A failure with no stored row -- a plugin enabled by a DEFAULTS entry, which is
exactly what plugin.http was -- would otherwise still be counted and still be
invisible.
Rows carry `removable`: only a plugin with a real stored row can be cleaned up,
so a default-declared one shows the reason and an explanation instead of a
Remove button that would delete nothing while the default reasserts it. Rows
with a reason read as an error (red, "Failed to load"); rows that merely have
leftover config stay a warning. A discovered plugin that failed is excluded --
its own card already shows the reason.
Replaces find_orphaned_plugin_names outright rather than adding a second
overlapping helper; it had one caller.

The operator's 500 was NOT the startup gap I attributed it to. They found it by
logging in and getting Steward's own error page -- which means create_app had
completed and the app was serving, so the gaierror came from a request handler
acquiring a connection, not from boot. Neither prior fix covers that: the
startup retry never runs, and pool_pre_ping only helps once the database is
back, since its replacement connect fails too while the container is gone.
Adds a before_request gate that acquires a pooled connection with a short
bounded retry (~1.75s over 4 tries) so a database restart is ridden out
invisibly, and renders a distinct 503 "database unavailable" page when the
budget is exhausted. The request budget is deliberately far shorter than the
startup one: nobody watches a container boot, but somebody is watching this
page load, and a page that hangs is worse than one that says what is wrong.
/health and static are exempt -- a liveness probe must stay answerable while
the database is down, or a dependency outage triggers a restart loop.
Credential and missing-database errors still propagate rather than being
reported as "unavailable", which would send the operator chasing the wrong
problem entirely.

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.

Two connection-recovery gaps, both surfaced by a Postgres restart that left
the app throwing tracebacks while the DB itself was healthy.
pool_pre_ping + pool_recycle on the app engine [#2626]: when the database
restarts, every connection already in the pool is dead at the socket level.
SQLAlchemy only discovered that by failing a real query, so the first
operation after a restart errored out on whatever triggered it. pre_ping
checks liveness on checkout and swaps the dead connection transparently;
pool_recycle caps connection age so a socket stranded by a NAT/conntrack
timeout or a Docker network rebuild is retired on a timer instead.
wait_for_database() gate at startup [#2627]: create_app touches the DB
synchronously (migrations, secret re-encryption, settings load) and assumed
it was both resolvable and accepting connections on the first try. Neither
holds after a host reboot (Docker DNS not yet serving `db` -> gaierror -2)
or an unclean shutdown (Postgres still replaying WAL -> "not yet accepting
connections"). Both are transient, so retry with capped backoff behind one
gate ahead of the first DB touch. Credential and missing-database errors
are classified by SQLSTATE and still fail immediately -- waiting cannot fix
those. Budget is bootstrap-configurable (STEWARD_DB_CONNECT_TIMEOUT /
database.connect_timeout, default 60s) since it governs reaching the DB and
so cannot live in the DB-backed settings.
Tests drive the retry loop off a fake clock, so backoff and timeout
behaviour are deterministic rather than wall-clock dependent.

M78 step 1. The bundled maintenance/docker_prune.yml was a single
`docker system prune -f`; the upcoming per-host prune buttons need a
granular split. Add a `prune_target` extra-var:
- containers → docker container prune -f
- images → docker image prune -f (+ -a when prune_all_images)
- system → docker system prune -f (+ -a / --volumes) — the DEFAULT,
so existing manual/scheduled callers (which set no var)
keep today's behavior.
Reuses the existing bundled playbook rather than adding parallel files;
keeps the description/category/confirm meta so it still self-describes as
a confirm-gated maintenance run. Adds unit coverage: the playbook stays
valid YAML, its meta still discovers, and all three targets are guarded.

Guardrails so the fd-leak class of bug (Errno 24 lockup; recent SNMP + UniFi
fixes) surfaces early or can't compound, instead of silently killing the app.
- Self-fd watchdog (steward/core/self_monitor.py): records open_fds and
open_fds_pct (% of soft RLIMIT_NOFILE) as "steward"/"process" metrics each
minute through the normal alert pipeline, so the operator can alert on them
via the existing alert-rules UI. Built-in WARNING floor at 80% gives a
zero-config early signal. Stdlib-only (/proc + resource); degrades to a no-op
off Linux. Registered as a core ScheduledTask in app.py.
- Poll-overlap guard (steward/core/scheduler.py): extract a pure _DueTracker
that skips a tick while a task's prior run is still in flight, so a hung poll
can't stack overlapping runs (which amplify per-poll resource/fd use). A
skipped task isn't penalised — it retries the next tick after it completes.
- fd-stability tests (tests/core/): _DueTracker overlap policy, the watchdog
metric/warning/degradation paths, and a real-fd canary that hammers tcp_check
and asserts /proc/self/fd doesn't grow.

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 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).
With docker enabled, "Docker" now appears under Infrastructure → its fleet view.

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.
- Tests: secret-key resolver (reuse existing file, generate when writable, raise
when unpersistable) and the undecryptable-secret detection helper.

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.

generate_inventory() emits Ansible's dynamic --list shape (all.hosts is a
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.

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).

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 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).

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.

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.
