failure.outcome_unknown_arm

Outcome arm names a failure the call cannot produce.

Area 3, Logic; not declinable; the next step is usually the agent's.

example
type LookupTimedOut = Failure {    kind: FailureKind.rejected}function unknown_failure(key: LookupKey) -> LookupResult {    return match lookup(key) {        success(value) -> value        LookupMissing -> "missing"        LookupRefused -> "refused"        LookupTimedOut -> "timed out"    }}
