Containment

Boundary condition

Containment is the boundary condition of the system. It defines the finite limits within which energy, actors, and constraints must operate.

Containment Diagram

A system is contained when

• energy cannot escape
• actors cannot expand the field
• constraints are fixed
• optionality is finite

Containment produces

• energy concentration
• volatility localisation
• directional narrowing
• collapse inevitability

Does not

• interpret behaviour
• describe intention
• predict actions

Signals

fixed boundaries · finite optionality · non‑expanding field · structural inevitability
