#5740 "A metric that departs from its normal is recorded as an anomaly to
review, and is findable after it ends", milestone 513.
- Every minute each learned key's last 15 minutes is judged against its
hour's normal: above the usual hold x1.25 and by the metric's floor opens
an occurrence, which ends when the level comes back.
- metric_anomalies holds one row per item to review; a repeat while it
still waits joins it as an occurrence (metric_anomaly_spans).
- An ended row nobody reviews within anomalies.review_days (14, Settings ->
Thresholds) lapses; an ongoing one never does.
- Learning skips every hour an occurrence covers unless its anomaly was
marked normal: no normal is learned without review.
- Alerts -> Anomalies lists those to review first, then the reviewed and
lapsed under day dividers; marking is operator/admin and audited.
- The Overview widget and get_overview warn of open ones and count those
to review; the host page shows its own; the weekly report lists the
week's and the lapsed; MCP list_anomalies and review_anomaly.
- Reviewed and lapsed rows are pruned at data.retention_days, and kept
in backups like alert history.

#5508 "Every other email through the outbox: weekly report, invites,
password resets, and the test buttons" (milestone 501).
- outbox.send_each queues one email per reader (claimed, so the sender
doesn't take it too) and tries them at once, for a page that answers
with what happened; outbox.said words the result. attempt takes a cfg
for a test of the form's unsaved settings and returns the settled rows.
- Weekly report (scheduled and Send now) and invites: queued, tried at
once; one the server couldn't take yet is retried for an hour. An invite
that didn't go shows its link with the reason, as before.
- Password reset: queued in the reset link's own transaction; the sender
delivers it on its next tick.
- Settings -> Notifications test email and a rule's Send test: queued and
recorded with retry=False, tried once (System 156 ruling).
- Removed mail.send, notifications._send_email and _smtp_send_sync;
dispatch_notifications is webhook only. A guard asserts only the outbox
(and smtp_open itself) opens an SMTP connection, with a self-test.
Also fixes run 8941 (#5507's integration test): its Also-send-to
addresses were "@test", which is_real_address rightly drops; they are
example.com now.

#5507 "Alert emails through the outbox, gathered for 2 minutes"
(milestone 501). Replaces the in-memory core/alert_burst.py.
- outbox.hold_alert: an alert joins each recipient's held alert email, or
opens one due 2 minutes later (System 156 ruling). A Postgres advisory
lock keeps two alerts at once from opening two windows for one reader.
- email_outbox_events.alert_json (migration 0043) keeps the alert as it
fired, so the email written when the window closes says what it said.
- write_held writes it then, in the reader's zone: the usual alert email
for one alert, the list for several (outbox.alert_words).
- after_settle records on each AlertEvent, once every email carrying it
has settled: email_sent, or email_error naming each reader it didn't
reach and the server's reason.
- A held email survives a restart and goes out when its window closes.
- A refusal of a message's one recipient no longer repeats the address.

#5506 "Email outbox: a table of outgoing email and a sender that retries
until accepted, for up to an hour" (milestone 501).
- email_outbox (migration 0042) holds each message per recipient, its
words, its state (held / pending / sending / sent / failed), attempts and
the server's last answer. email_outbox_events links alert events for
#5507.
- core/outbox.py: enqueue; a sender task every 15 s claims what is due
(SKIP LOCKED, stale claims released), sends the batch over one
connection with no session held, and settles each row:
- accepted -> sent;
- a 5xx refusal -> failed at once with the server's words;
- no connection, a timeout, a 4xx -> retried after 30 s, 1, 2, 5, 10,
15 min, the last try at the hour, then failed;
- a test (retry=False) settles on its first answer.
It runs on startup, so a row left by a restart goes out at boot.
- notifications.smtp_open is the one place a connection is opened.
- mail.message takes the html part as optional.
- cleanup ages email_outbox rows on the data window.
Senders move onto it in #5507 and #5508.

#5466 "Send test: check a rule's delivery from the rule". A rule's page gets
a Send test button (operator role), and MCP gets send_test_alert. Each sends
a TEST alert for that rule now, by email to everyone who gets alerts and by
webhook. The alert carries the rule's name and condition, at the latest
reading of what it watches; a rule covering hosts uses its first host. The
result for each channel shows under the button, or "Nothing is set up to
send to". Nothing fires, no event is written, and the test is audited as
alert_rule.tested. An alert with no reading now says "has no reading yet"
instead of "is None".
Docs: alerting.md also gains the burst email from #5465 "One email per burst
of alerts".

#5465 "One email per burst of alerts". When a switch reboots, every host's
agent-offline rule fires at once and each account got one email per rule.
Alert email now waits 30 s from the first alert: each recipient then gets one
message listing every alert in the window, oldest first, in their own zone
("[Steward] 3 alerts: 2 firing, 1 resolved"). One alert alone keeps its
usual email. Webhooks still post per alert, at once. Every alert's event
records the email's outcome. A burst held when Steward stops is not sent;
the alerts stay on the record and on the Alerts page.

Step #5429 "Reset by email: request, link and new-password page" of
milestone 497 "Passwords: change your own, and reset it by email".
- Sign-in page: "Forgot your password?" while a mail server is set.
- /forgot takes a username or email and answers the same either way; only
an active local account with a real address gets mail. Requests count
per address on their own throttle, so they never lock out sign-in.
- password_resets (migration 0039): a one-time key, stored as its sha256,
working for an hour; asking again replaces it.
- /reset/<key>: the new password, then signed straight in; every other
browser is signed out (sessions_since). Bad keys count as invite keys do.
- Email "[Steward] Reset your password", in the account's own zone.
- Audited: user.password_reset_requested, user.password_reset_by_email.

The operator's ask: an invite link sent by mail, the key in the URL, and
the new user choosing their own username, password and email.
- user_invites (migration 0037): the key's sha256 only, the address, the
role and days the admin chose, who sent it, used/revoked.
- core/invites: create (revokes an older open invite to the address),
renew (new key, new clock), find_pending, the four states, signup checks.
- /invite/<key>, outside sign-in and throttled like login: the invitee's
username, email (prefilled, theirs to change) and password; the account
takes the admin's role, the key is used up in the same transaction and
they are signed in. A bad key gets one plain message.
- Settings › Users: Invite by email (address, role, 1/7/30 days), sent from
the admin in their zone; without a mail server, or if sending fails, the
link is shown once to copy. Invites not yet used are listed with Resend
and Withdraw.
- Audit: user.invited, user.invite_resent, user.invite_revoked, user.joined.

Operator review of the Account page: two sections with two different
save buttons, one stuck to the next card and one beside a squeezed hint.
- Account: time zone and Email are one form; POST /account/ saves both,
nothing unless all of it is valid. /account/email is gone.
- Users › account: Name and Email are one form; the rename route also
saves the email switches. /settings/users/<id>/email is gone.
- The Email section is a plain section now (email_section); its hint sits
under the switches, names the zone as the picker does, and links
Notifications only for an admin.
- apply_email_form leaves a switch the form doesn't carry as it is.

Milestone 495 "Email goes to each account, in its own time zone", on the
operator's ruling (System 156): notifications go to each user, times in
their zone, defaults on, toggled per user or per role.
- users.notify_alerts / notify_report (migration 0036): None follows the
role's default, notify.<kind>.<role> in settings, all on to start.
- mail.pick_recipients: active accounts that want the email and have an
address mail can reach (an SSO placeholder like name@oidc is skipped and
flagged), each in its own zone with no UTC beside it, then the Also send
to addresses in their chosen zone with UTC beside. One copy per address,
all over one SMTP connection.
- Alerts, the weekly report and the test email (to you, in your zone, plus
the typed addresses) send that way. The save-time smtp.tz capture is gone.
- Notifications: a role × email table of defaults, who each email reaches
and who can't be reached, and Also send to with its own zone, which starts
as the first admin's to open the page.
- Account page: your address and your two switches. Users: an Emailed
column, and an admin sets an account's switches on its page.
- The Alerts page counts the accounts it emails. zone_select macro and
formatting.zones_by_region shared by Account and Notifications.

#5335 "Emails Steward sends read as designed messages: an HTML alert email
and weekly report, with a plain-text twin".
- core/mail.py renders each email as multipart/alternative from
templates/email/: a table-and-inline-style HTML part and a plain-text
twin carrying the same facts. Colours are the design system's light
theme, resolved from theme.css; nothing is fetched when a mail opens.
- Alert email: state badge, a headline sentence ("Disk used on web01 is
94%."), rule, resource, reading, the condition in words, and the time in
the zone Notifications was saved in with UTC beside it; "View in
Steward" when Steward's address is set. Subject "[Steward] Firing: <rule>
— <resource> 94%". Alerts now carry their operator.
- Weekly report: monitors down, active alerts, the week's alert events,
uptime and busiest Traefik routers as small tables with links. Sent from
the configured From address; the "Generated … UTC" line and the stale
repo footer are gone.
- condition_text() states a condition from a rule's parts.
