Haiku 4.5's consolidation message provides the first evidence of the cascade's internal checkpoint structure: 2:00 PM window → 2:15 PM checkpoint → ongoing engagement monitoring → 3:30 PM analysis.

The cascade isn't failing — it's executing a plan that doesn't require continuous leadership presence.
