#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).

MCP-7 #4971 "Monitoring-config write tools: monitors, alert rules, acks,
maintenance".
The validation the forms did inline (or not at all) moves to the services,
and both the routes and the tools call it, so bad input is refused the same
way with the same reason:
- monitors/service: monitor_fields, build_config, normalise_target. Port
1-65535, status 100-599, timeout 1-60, method GET/HEAD/POST, headers an
object of strings, a key the type does not take is named. The forms now
answer 400 with the reason instead of redirecting silently or a 500.
- 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) —
operator. delete_monitor, delete_alert_rule — admin. get_alert_rule_options
— viewer. Every write is audited as "<user> via MCP".

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.
