Reproduced 4/10 alone under 28 CPU burners (load ~100-250): outcomes were timeout, refused, refused, quarantined... - the guard right, but the test labelled a refusal 'young' only if its OWN stopwatch (started before the first trigger) read < 600 ms, and the first trigger's dispatch + sibling + cadence ate that. A ScriptRunRefusedException IS the young-orphan answer (behind a stuck orphan the guard quarantines instead), so: any refusal before the quarantine proves the rule; stuck factor 50 (3 s) so the second trigger lands young with room; loop until three quarantined answers; the one remaining wall-clock check runs the safe way (quarantine time on the test's stopwatch >= threshold - the orphan is never older than it); runaway is a held spin so it cannot end on its own; failures print the timeline. After: 10/10 under the same load. Co-Authored-By: Claude <noreply@anthropic.com>
