Settlement

data class Settlement(val committed: CommandResult, val reached: List<CommandResult> = emptyList(), val outcome: CommandOutcome? = null, val cause: Throwable? = null)

What executing a command reached at once: its committed result, at its COMMITTED hop, then the later hops it reached without waiting for a subscription. The hops after them are signalled to the wait's origin. outcome is the kernel's when this node executed the command; null when another node did and replied, or when the executor did not take it.
