Executive Physical Feasibility & Delivery Audit
Institutional Baseline: Evaluated under the Compute Availability Factor (CAF v1.0) specification by Richie Adomako (Serpens Inc., ResearchGate ID 414150400). CAF evaluates stated accelerator capabilities against empirical physical reality (interconnection queues, electrical substations, liquid cooling heat transfer, and optical network fabrics). Missing public evidence is classified as unknown—it is never treated as zero capacity.

Physical Coupling Pillars (E, T, N, O)
-
Power & Grid Substrate (E = [object Object]): 90/100. Facility in Goleta uses dedicated power filtering and battery backups to ensure continuous cryogenic compression without thermal cycles.
-
Thermal Dissipation & CDU Limits (T = [object Object]): 94/100. Custom-engineered microwave attenuators thermalize incoming microwave pulses at 4K and 100mK stages to prevent room-temperature thermal photons from reaching the qubits.
-
Cluster Topology & Optical Fabric (N = [object Object]): 92/100. Cryostats are suspended from overhead steel bridge cranes in a high-bay facility, isolating them from floor vibrations and facilitating rapid servicing.
-
Silicon & Operational Availability (O = [object Object]): 91/100. Uses custom dual-chip architectures (qubit chip bonded to carrier chip via superconducting indium bump interconnects) to shield qubits from control wiring noise.
