    # Parses the WebhookEvent payload every Strike webhook POST carries —
    # {id, eventType, webhookVersion, data: {entityId, changes}, created,
    # deliverySuccess}. Deliberately does NOT carry the changed values
    # themselves — Strike's own docs are explicit that the event never
    # contains the actual data changes, only that something changed on
    # `entity_id`. A real value only comes from calling the matching
    # fetch endpoint (e.g. Invoices#find for an invoice.* event) —
    # trusting anything else here would mean trusting an unauthenticated
    # claim about money having moved.
