Snapshot ladder for one simulated day
The forecast
Sets the requirement curve in capture 1. The roster does not move with it.
Event size
Planned into capture 2, so its size also shapes the published schedule.
What the day actually did. No capture moved for it. The tidy edit is what moves.
Five captures of the same day

Every change between adjacent captures
Each row is one change, the pair of captures it sits between, where it came from, and what it did to on-queue coverage at day grain.
Benign drift against signal drift
Both kinds move real hours. Only one of them is safe to summarize by its net.

What the edit does to the number
The number can still be tidied. It just can no longer lie.
