The Mother Equation of the Quantum Blueprint Formalism contains a diffusion term Dₛ∇²ρₛ whose Laplacian ∇² requires a Riemannian metric on the configuration space Xσ of distinction values. This paper shows that the Hessian of the tension functional Φext is not positive definite at pointer states (demonstrated by an explicit three-distinction example with eigenvalues −1, −1, +2) and therefore cannot serve as the metric. Instead, the metric on Xσ is the background ℓ² inner product provided by the structural choice (SC) of implementing the formalism on a smooth Hilbert manifold. The tension functional Φ plays the role of the potential—determining masses and interactions via the spectrum of the Fokker-Planck operator—not the role of the metric. This parallels the standard QFT architecture where the kinetic term (metric) and the potential are independent structures. The paper makes four further contributions. (A2) provides the metric on the re-entry fiber Xf via the decomposition of the circulation field Ωₛ under the filtration ℱ₀ ⊂ ℱ₁ ⊂ ℱ₂ (Theorem 4.1). (A3) constrains the spectrum of the Fokker-Planck operator (Proposition 5.1). The circulation parameter λ is derived without circularity as a curve integral along flow lines (Theorem 6.1). An inconsistency in the existing corpus—the Hamiltonian vector field XΦ vanishes at pointer states, conflicting with |Ωₛ| ≥ Ωmin > 0—is identified and resolved by proposing the decomposition Ωₛ = XΦ + Ωvac with a vacuum circulation component. Physical time tΘ = ∫|πΘ*Ωₛ| dλ is determined by all three content types of D: distinction values σ control the classical circulation speed, incompatibilities ω control whether time exists, and the re-entry pattern f controls its qualitative character. Mₛ is pre-spacetime, not pre-metric.
