Struct StartOutcome 

pub struct StartOutcome {
    pub handle: WorkflowHandle,
    pub display_name_not_applied: Option<DisplayNameNotApplied>,
}

What Client::start returns: the started (or idempotently replayed) run, plus the note that a requested display name was NOT applied.

The note exists because display_name is deliberately outside [StartFingerprint]: the fingerprint answers “is this the same act?”, and a label carries no identity, so two starts differing only in name are the same act and dedupe to one run. That leaves a second, different name with nowhere to go — and dropping it silently would hand the caller a run wearing a name they did not ask for while saying nothing. So the drop is REPORTED here instead. The replayed run keeps its EXISTING name; nothing is renamed behind the caller’s back.

Fields

handle: WorkflowHandle

Handle to the started run, or to the existing run an idempotent replay matched.

display_name_not_applied: Option<DisplayNameNotApplied>

Present ONLY when this call REQUESTED a display name, an idempotency-key replay matched an existing run, and that run does not already wear the requested name — whether it wears a different one or none at all.

None on every other path: a first start (which applies the name it asked for), a replay that requested the same name, and — the rule this field’s absence states — any call that requested NO name. A caller who asked for nothing had nothing dropped, so there is nothing to report, even when the standing run wears a name of its own.
