Causality Engine v2.1

Verify that major turns arise rather than merely happen. A plot that moves is not the same as a plot that moves because of what came before.

Chain model

For each major turn, model in order:

1. Prior conditions — the established state that made the turn possible.
2. Trigger — the immediate event that set it off.
