# Boundary **Domain:** Systems / Philosophy / Design **Doc Type:** Concept Node **Maturity:** Developed ## Definition A **boundary** is a distinction that identifies where a system, form, category, or jurisdiction is treated as ending and another begins. Boundaries separate, but they also create interfaces through which exchange, translation, control, and relation become possible. Boundaries may be physical, conceptual, institutional, computational, or perceptual. Their placement is consequential: changing the boundary changes what belongs to the system, what is treated as environment, and which interactions become visible. ## Corpus Context The corpus uses boundaries to connect [[wiki/Cybernetics|Cybernetics]], identity, governance, and representation. A boundary is therefore both a limit and a relationship. ## See Also [[wiki/Form|Form]] · [[wiki/Agency|Agency]] · [[wiki/Perceptual Sovereignty|Perceptual Sovereignty]] · [[wiki/Model-Based Governance|Model-Based Governance]]
