## 🏃 Autonomous 18-Meter Obstacle Traversal Demonstration
Inside an American Ninja Warrior MuJoCo humanoid simulation, without dense Transformer attention or sample-inefficient deep RL, the PCEI agent autonomously accelerates down the high-momentum Sprint Runway (Stage 0), bounds across the angled 45° Quad Steps (Stage 1), and touches down cleanly at **18.00 meters** on the Stage 2 Balance Beam platform:

## 🧠 Architectural Foundation
Standard monolithic Transformer architectures fail at high-frequency continuous control due to quadratic latency scaling ($\\mathcal{O}(L^2)$) and unbounded memory buffers. The PCEI robotic controller unifies three core principles:
1. **Selective State-Space Recurrence (Mamba SSM)**: Linear $\\mathcal{O}(L)$ compute with constant $\\mathcal{O}(1)$ memory buffer, updating continuous proprioceptive and LiDAR representations at 40 FPS without latency spikes.
2. **FastKAN Cubic B-Spline Torque Manifolds**: Non-linear spline basis functions (`FastKANMixer`) placed in residual branches enable smooth, biologically plausible motor activations that prevent actuator jerk and joint instability.
3. **Discrete 1.58-Bit Ternary Synaptic Gating**: Weight quantization constrained to `{-1, 0, +1}`, providing homeostatic metabolic efficiency and biological zero-inhibition.
