# Contract — Alert Event Types (workspace alerts)

## Overview

This add-on introduces a single new event type used for *test deliveries*.

## Event Type

- `alerts.test`
  - Purpose: user-triggered “Send test message” action on an alert target.
  - Storage: `alert_deliveries.event_type`
  - Delivery: sent via the existing alert delivery pipeline (`DeliverAlertsJob` + `AlertSender`).

## Notes

- This is an internal event type string; it is not a Microsoft Graph contract.
- No secrets are stored in payload/error text.
