When an uptime check opens an incident, every member of the Organization who wants uptime email gets "api is down in shop / production". It says visitors can't reach api, since when, and that another email follows when it's back. When the incident closes they get "api is back up in shop / production" with how long it was down. Members who set uptime to None in Account → Notifications get nothing. An alert the control plane wrote more than an hour ago never sends.

Down	Recovered

What changes

send-uptime-alerts is a new Inngest cron, once a minute, concurrency 1. It reads the uptime_alert outbox the control plane already writes on each incident transition.
Each run first marks pending and sending rows older than one hour expired, then claims up to 100 rows with FOR UPDATE SKIP LOCKED and moves them to sending. A row left in sending by a run that died is claimable again after five minutes, up to five attempts.
A claimed row becomes mail through E2's queueOrganizationMail with type uptime and key uptime:<incident>:<opened|resolved>, so the per-recipient idempotency key is stable across retries.
A recovered alert waits while its opened alert is still pending, and expires without mail if the opened one expired or failed. Nobody gets "back up" for a "down" they never got.
"View incident" opens the Service's Monitoring tab zoomed on the incident with the same range the tab uses. Times are UTC, because there is no per-user timezone.
Templates are MailContent builders in src/modules/uptime/alert-mail.ts, on E1's renderMail.

For maintainers

Shared change: scripts/mail-preview.ts now renders every sample (sample, uptime-down, uptime-recovered) and refuses MAIL_TO other than nick@ployz.dev. Pass sample names to send only those. E5 and E6 add their samples to the same map.
Project and environment names come from config_environment and config_project by SQL, as uptime-sync.server.ts already does. The Store SDK has no server-side lookup by id.
uptime_alert.state values used: pending, sending, sent, expired, failed (incident row gone).

How it was proved

vitest run --project postgres src/modules/uptime/alert-mail.postgres.test.ts: 5 passed. The tests write incidents and alerts with the control plane's own controlPlaneStatements, then assert: an opened incident mails Ada once across two runs and skips Bob (uptime set to None); a closed incident mails down then back up with "It was down for 12 minutes."; an alert written over an hour ago expires and its recovery never mails; two concurrent runs over three incidents queue exactly six distinct mails; the cron function sends what is pending.
pnpm typecheck and oxlint --type-aware on the changed files are clean.
Real sends of an earlier wording to nick@ployz.dev through PostShiba with pnpm mail:preview uptime-down uptime-recovered: down returned sent, message id ef43dd03-9de5-4edb-89fd-346b580b3c2f@ployz.dev; recovered returned sent, message id 35db116b-bae3-47ee-a89b-d572daf7d1cb@ployz.dev.

📝 Summary

Summary by CodeRabbit

New Features
- Added email notifications when a monitored service goes down and when it recovers, with incident details and links to the relevant monitoring view.
- Uptime alerts are sent to members whose notification preferences allow them. Pending alerts are delivered automatically, and sample outage and recovery emails are available for previewing and testing.
Documentation
- Clarified that uptime incident emails may be skipped if they cannot be sent within an hour. Preferences for other email types take effect when those emails are sent.

The change adds opened and resolved uptime alert emails, a server-side sender for pending alerts, and a one-minute Inngest schedule. It adds integration tests, updates notification documentation, and extends the mail preview script to render and send named samples.

Changes: Uptime alert emails

Layer / File(s)	Summary
Alert email content and samples `dashboard/src/modules/uptime/alert-mail.ts`, `dashboard/scripts/mail-preview.ts`	The email builder formats opened and resolved incident details, including failure information, outage duration, UTC times, and Monitoring links. The preview script renders the existing and uptime alert samples as HTML and text. When sending, it accepts selected sample names and restricts the recipient to `nick@ployz.dev`.
Alert claiming and delivery `dashboard/src/modules/uptime/alert-mail.server.ts`	The sender expires alerts older than one hour and claims eligible alerts with a five-minute lease. It queues opened alerts, defers resolved alerts while their opened alert is pending or sending, and updates alert state after processing.
Scheduled execution and validation `dashboard/src/modules/uptime/alert-mail.inngest.ts`, `dashboard/src/modules/inngest/index.ts`, `dashboard/src/modules/uptime/alert-mail.postgres.test.ts`, `docs/user/account/notifications.md`, `docs/user/production-checklist.md`	An Inngest function runs the sender every minute with three retries and concurrency limited to one. Integration tests cover recipient preferences, recovery emails, expiry, concurrent claims, and scheduled execution. The documentation describes uptime alert emails and their delivery timing.

_{_{P1 Badge}} Track cancellation for claimed alert rows

When an operator cancels this Inngest run after its step has claimed rows, the rows retain sending without the owning runId or a cancellation handler; the next cron can reclaim them after the lease and send mail despite the cancellation. This durable workflow should use attemptLifecycle to associate claimed rows with the run and move them to a terminal state on inngest/function.cancelled.

AGENTS.md reference: dashboard/AGENTS.md:L24-L24

Useful? React with 👍 / 👎.

NNick29d ago

Not taking this. This cron doesn't create the rows; the control plane writes uptime_alert, and the cron is a sweep. A row it leaves in sending never stays active: the next run reclaims it after the 5 minute lease, and any pending or sending row older than an hour becomes expired. Cancelling one sweep run isn't a request to drop the alert, so sending it on a later run is the intended outcome.

_{_{P1 Badge}} Enforce the expiry cutoff in the mail consumer

When the shared send-mail function receives more than 100 events in an hour, its global throttle in mail.inngest.ts:47-56 defers the excess. This code checks age only before queueing and then marks the alert sent as soon as the events are emitted, so a deferred uptime event has no deadline and can be delivered hours later even though the user documentation promises that alerts unable to go out within one hour are skipped. Carry the alert deadline into the event and reject stale mail at the actual send boundary.

AGENTS.md reference: AGENTS.md:L6-L6

Useful? React with 👍 / 👎.

NNick28d ago

Declining here. The deferral needs one Cloud to queue more than 100 emails in an hour, which is PostShiba's cluster cap, so late delivery only happens when the cap is already saturated. A deadline in the shared send-mail consumer would change every email's send path, and this PR is about the uptime trigger. Noted as a follow-up for the mail consumer.

5	Learning: For uptime notifications in Ployz, the control plane writes an `uptime_alert` row when the check goes down or recovers. The one-hour expiration uses `uptime_alert.created_at`. In `docs/user/account/notifications.md`, describing this window as starting when the check goes down or recovers is appropriate.
