Concepts
Understand the design decisions and mental models behind WorkSpec.
Timeline versus simulator
Understand predetermined timeline effects and causal state-driven simulation as different modeling tools.
A valid file is not necessarily a valid world
Understand the difference between structural correctness and domain truth.
Why one authoritative run matters
Understand why snapshots, Constraints, playback, and rendering must share one resolved history.
The jigsaw model
Understand WorkSpec as sparse known facts completed and challenged by domain Constraints.
WorkSpec as inspectable world modelling
Understand how objects, state, time, execution, Constraints, and presentation form an inspectable model.
