Concepts

Events are the record

Every business action is captured as an immutable event with full context. State is derived from events, not the other way around.

Two pure functions

decide turns commands into events. evolve folds events into queryable state. That's the programming model.

Bi-temporal by default

Every event carries transaction time and effective time. "What did we know, and when did we know it?" is a query, not an investigation.
