A fixed, non-adaptive Tensor P2 quantum kernel was executed continuously on two microcontroller platforms—a Raspberry Pi Pico (QCC Echo-Origin) and an ESP32-S3 (EchoLift Harmony; radiation-hardened adaptation)—to assess runtime stability and entropy behavior under ordinary conditions. Devices ran openly on a dining-room table at room temperature, unshielded and unenclosed. Each platform completed 2-, 30-, and 60-minute soaks. For all runs on both devices, outputs matched their reference simulations with no drift or corruption: 0.00% measured entropy leakage and continuous coherence lock. Long soaks were visually traced on a live plotter to confirm uninterrupted loop progression. All sessions were video-recorded and SHA-256 hashed. An independent quantum-security reviewer (Francisco Javier "JJ" Jimenez, CEO, QuantumThreat Labs) directly observed the Qiskit kernel trace, the live hardware runs, and a perturbation check, and signed a validation statement. These results provide an empirical baseline for Tensor P2 behavior across heterogeneous controllers at room temperature.
