The Group Form of Law: The Construction Form of the Minimal Sedimentation Field

How can a system’s history become part of what generates its subsequent behavior? Rather than deriving its definition from an existing neural-network architecture, this paper explicitly constructs a minimal runnable sedimentation field whose later dynamics can be altered by its own history. External action must enter the system and produce a trace-response; that response must persist across time and contribute to relational organization; and the resulting historical structure must genuinely participate in subsequent generation. If a load-bearing sedimentary structure is removed or severed while present re-entry conditions are held fixed, later flow must change detectably. The paper gives an explicit Canonical F* together with four core operators—Trace, Sediment, Decay, and Continuation—and closes the required offices of entry, persistence, relational organization, historical participation, decay, and present flow.
