        "Current Mixture-of-Experts (MoE) architectures and autoregressive world models suffer from three structural "
        "pathologies: limit-cycle router thrashing across non-consecutive tokens, static over-allocation of compute budget "
        "regardless of prompt entropy, and compounding epistemic drift over long rollouts. In this work, we present "
        "<b>SCE-Fiber</b>, an energy-conserving control substrate for massive sparse models (demonstrated on 35B parameter scales "
        "with 128 physical experts). By restructuring flat expert topographies into eight semantic domain fibers and applying a "
        "critically damped Hamiltonian update (&zeta; = 1.0), our framework eliminates oscillatory domain switching while "
        "reducing active parameters via dynamic Upper Confidence Bound (UCB) dead-work pruning. Furthermore, we formulate an "
        "invariant world manifold that bounds simulated transitions via LaSalle-Lyapunov invariance (V(x) = x<sup>T</sup> P x). "
        "Backed by a sub-microsecond CPython native kernel (0.76 - 1.46 &mu;s latency), empirical benchmarks on an NVIDIA GeForce "
        "RTX 3090 demonstrate a 37.5% - 75% reduction in active FLOPs while preserving foundational baseline accuracy and providing "
        "instant zero-waste state caching."

        "tokens oscillate across uncoordinated experts without inertia; (2) <i>Static Compute Over-Allocation</i>, which expends identical "
