↳ CAF WATCHER // CONTINUOUS PHYSICAL AUDIT LEDGER

Naver (HyperCLOVA X & GAK Sejong) Grade A

South Korea's sovereign AI champion: HyperCLOVA X foundation models anchored to the LEED Platinum GAK Sejong mega-datacenter · Category: Asian AI Frontier

Executive Physical Feasibility & Delivery Audit

Institutional Baseline: CAF Watcher 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. Operator telemetry strengthens assessments, but participation is never mandatory.

Physical Coupling Pillars

Power & Grid Substrate (E): 86/100. GAK Sejong secured dedicated 154kV underground transmission feeds directly from KEPCO, bypassing metropolitan Seoul's acute grid congestion.
Thermal Dissipation & CDU Limits (T): 90/100. Naver is a global pioneer in natural wind economization, using the natural mountain microclimate of Chuncheon and Sejong to cool servers without mechanical compressors for over 7 months each year.
Cluster Topology & Optical Fabric (N): 88/100. Custom-built campus featuring seismic isolation bearings capable of withstanding magnitude 7.0 earthquakes, with massive floor loading capacity for liquid-cooled AI racks.
Silicon & Advanced Packaging (O): 82/100. Benefits from direct proximity to South Korean semiconductor titans (Samsung Electronics and SK Hynix), co-developing next-gen memory-efficient AI accelerators.

Attributable Public Evidence Ledger
