STACK MIL04 is the four-building Vellezzo Bellini campus in Pavia. Building cards total 64 MW, while current campus prose and the independent register describe 60 MW. Cartis publishes the location, four-building plan and infrastructure context but withholds the headline until STACK reconciles the campus total. The capacity or identity headline remains held until the named conflict is resolved; no automatic merge is authorized.
