Boundary-Belief

Canonical definition

A Boundary-Belief is a maintained Belief whose function is to separate one Belief-domain from an adjacent one, rather than to make a claim about the state of affairs inside a domain. It is the Belief that a region of Belief is distinct, that valuations, evidence, and authority proper to one field do not automatically carry into another. A Boundary-Belief is held in the Belief Register like any other Belief and persists only while actively maintained; it carries no exogenous Referent of its own, so it neither decoheres against reality nor self-corrects. Its strength sets the Coupling Strength across the membrane it forms between two domains in the Bubble-and-Foam Model: a strongly-held Boundary-Belief keeps that coupling low and contains a collapse within its domain, while a decohering Boundary-Belief raises coupling and lets a collapse in one domain relocate its Content-Beliefs into the neighbour. Distinguished from the Content-Belief, which makes claims within a domain rather than separating domains.
