Expand description

An event emitted when the database state changes.

Covers all mutation types for event sourcing. New variants can be added without breaking old readers thanks to #[serde(other)] on the Unknown fallback.

Externally tagged (default) for bincode compatibility. JSON uses {"EpisodeCreated": {...}} style.
