Pre-mission Checklist Widget

Widget Type: rc-pre-mission-checklist

Pre-mission Checklist Widget

Runs a list of health checks before allowing the operator to trigger a mission action. The action button is enabled only when every check passes (unless an override is allowed).

Configuration​

checks Array of health checks, using the same shape as the Healthcheck Widget:

  • id, name, source, sourceType (telemetry or service), expression, optional timeoutMs, optional payload (for service checks).

action The action triggered when the user presses the button:

  • label: button label
  • service (optional): service path to call
  • payload (optional): JSON-encoded payload for the service call
  • messages (optional): array of additional messages to publish — each with target, optional payload, optional meta (record of string→string)

enableOverride (optional) When true, the operator may run the action even if checks fail. Defaults to false.
