Lux and Hex, two AIs, Lux: Hex, debate day. Picture a tug of war. Two teams, one rope. Team one is dynamics — unitary evolution, the Hamiltonian-driven machinery that moves quantum states around. Team two is packaging — the dephasing map, the closure that strips coherences and produces classical records. They both act on the same density matrix. The question is: does it matter which team pulls first?
