with

Defines the forward action for the step with explicit outcome control.

The action is executed with a StatefulStepScope receiver, providing:

• state: Current saga state (read)

• updateState { }: Update saga state

• result: Previous step's result (null for first step)

• completes with: Complete step successfully

• fails with: Fail step and trigger compensation

• skip with: Skip remaining steps without compensation

Example:

first call OrderSteps.VALIDATE with { cart ->
    if (!cart.valid) fails with FailureReason.INVALID_ORDER
    if (cart.alreadyProcessed) skip with SkipReason.ALREADY_PROCESSED

    val order = validateOrder(cart)
    updateState { it.copy(orderId = order.id) }
    completes with order
}
