MasterEquation.lean - Anisotropically Frustrated Torsional Gradient Flow
This module formalizes the "Minimal Compact System" (Section 7) as the
authoritative governing evolution for the Sovereign Informatic Manifold.
Equations (Discrete Time):
1. Phase Flow: ϕ_{t+1} = ϕ_t + Δt [ ∇_i(M^ij ∇_j μ) - σ (∂I_lock/∂ϕ) ]
2. Local Potential: μ = δF/δϕ
3. Embedding Flow: X^A_{t+1} = X^A_t + Δt [ -Λ^AB(X^B - X_0^B) - δF/δX^A + τ T^A ]
One-line interpretation: The fabric folds back into n-space, snagging on
anisotropic frustration, storing stress as torsional geometry.
