Ideal complexity
Architecture should be sufficient—never merely larger.
Ideal complexity is the least architecture sufficient for the required purpose, obligations, authority, representation, and responsibility at the selected cut. Too little architecture leaves necessary commitments or responsibility unconstituted. Too much architecture invents integration, central authority, or collective purpose that the setting does not require.
The practical discipline is therefore diagnostic before it is interventionist: identify the actors, classify the relation, reconstruct represented action, localize responsibility, and alter only the architecture whose absence or excess has been demonstrated.
