Enum Outcome 

pub enum Outcome {
    Ok,
    Status(u16),
    Skip,
    Halt,
}

What a call tells the engine. v3’s TaskOutcome, unchanged.

Exhaustive on purpose: a host matching on it handles every case, and a fifth would be a new contract, not a minor addition.

Variants

Ok

Normal completion: the audit trail records status 200, and the workflow continues.

Status(u16)

Completion with an HTTP-like status, recorded on the audit trail. A 4xx is a rejection and a 5xx a failure, handled by the task’s on_rejection and on_failure.

Skip

No audit entry is recorded, and the workflow continues.

Halt

The audit trail records status 299, and the rest of the workflow does not run. Later workflows still see the message.
