scriptOutcome method
Queues an outcome for the next deliver, applied synchronously before the handle is returned.
This models core rejecting a trigger outright — an unknown campaign key,
an invalid config, a frequency gate that answers immediately. The plugin
gets back an already-settled presentation, which is the whole point of
deliver being total: one caller code path either way.
For an outcome that arrives later (a dismissal, a deferred verdict), don't script it — deliver normally and call settle when the scenario says so.
Implementation
void scriptOutcome(PresentationOutcome outcome) => _scripted.add(outcome);
