// Emit a simple event
emit invoice_processed {
    invoice_id = result.invoice_id
    vendor = result.vendor
    total = result.total
    processed_at = now()
}

// Emit conditionally
if escalated {
    emit escalation_triggered {
        customer_id = customer.id
        reason = escalation_reason
        severity = :high
    }
}

Properties:

• Fire-and-forget (no return value, no delivery confirmation)
• At-least-once delivery (events may be delivered more than once)
• Per-source ordering (events from same Core arrive in order)
• Transport handled by Host's EventBus implementation
