The Quantum Blueprint Formalism (QBF) and Karl Friston’s Free Energy Principle (FEP) both derive Fokker-Planck dynamics from structural conditions. This paper performs the first explicit term-by-term mapping between the two frameworks. The QBF’s Mother Equation and the FEP’s Langevin dynamics are shown to be the same equation with different decompositions, different constraints, and different interpretations. The reversible sectors are identical: the QBF’s tension functional Φ equals the FEP’s surprisal (up to a factor Dₛ), and the equilibrium distributions coincide. The irreversible sectors differ in one structural point: the QBF constrains the solenoidal (divergence-free) flow via the symplectic form ωI (from non-commutativity), while the FEP leaves the solenoidal component as a free antisymmetric matrix Q. This difference produces a testable prediction: in the QBF, the solenoidal flow is Hamiltonian (generated by a symplectic form applied to the gradient of the potential); in the FEP, it can be any divergence-free field. Measuring whether biological solenoidal flows are consistently Hamiltonian would discriminate between the two frameworks at the biological level, without requiring the QBF’s full derivation of spacetime. Five points of agreement and three points of disagreement are identified. The frameworks are nested: the FEP is the restriction of the Mother Equation to systems that already possess spacetime and a Markov blanket.
