Linked contracts are a floor, not a census. Coverage is bounded by how distinctively a program is named and, for performer links, to RDT&E and Procurement — O&M and military construction publish no performers. Budget figures are FY2027 request dollars; contract figures are obligations. The two measure different things and must never be summed together.
