Struct CeremonyTransitionRecord 

pub struct CeremonyTransitionRecord { /* private fields */ }

One move a session made, and who made it.

A session used to keep only the state it was in, which answers where it is and never how it got there. Nothing could be said about a move — not that it happened, not who fired it, and above all not why — because there was nothing to point at.

The author is optional and that is not a gap. A transition fired by a seat has one; a transition the engine took because its guards came true does not, and naming someone would be inventing them.
