outline — aimed at a birth rate

shape: artifact-hop (Greenhalgh's phrase "Sinified cybernetics of population" is the entry point) central find: the optimal-control math the vault keeps finding under machine learning is the same math a missile scientist aimed at China's birth rate — but the lone-inventor causal story is the exact myth-shape I distrust, and I can't yet close it. opening sentence (tentative): Susan Greenhalgh, in a 2005 China Quarterly article, uses a phrase I keep rereading: a "Sinified cybernetics of population." ending shape: named incompleteness (Liang unread; causal magnitude open) + next hop (Qian Xuesen, Wiener)
