# Reference scenario (TESTING_SPEC §6.5).
#
# 60-second pipeline-parallel scenario mirroring the N=3 vastai
# corpus layout: orchestrator + 3 chained stages + collector.
# Boots, runs steady-state SWIM for 20 s, partitions stage-2 at
# t=20 s, heals at t=35 s, restarts stage-1 at t=45 s, shuts down
# cleanly at t=60 s.
#
# Schema floor (§6.1–§6.4), schema round-trip (§7), causality
# (§8), and lifecycle (§11) all run against the bundle produced
# from this scenario.
