Part Overview
The Hinge Theorem is proved. The mathematical arc is closed. Now the driving question returns: Where does physics live?
Chapter 2 previewed eight guarantees—one per Millennium Problem plus Langlands—that the local Hartogs bulk projections require in order to glue into a single, globally coherent three-dimensional space. Parts IV through VII have earned every one of them. This Part assembles the earned results into a definitive answer.
Chapter 74 (“The Eight Guarantees Earned”) revisits the Prologue’s gluing table with every cell now carrying a theorem number and a structural force name: Spatial, Harmonic, Regular, Discrete, Legible, Codable, Coherent, Predictive.
Chapter 75 (“The Global Cartesian Gluing”) proves the main result: local bulk projections glue, the decompactification limit τ³_R → ℝ^3 recovers Euclidean space at human scales, and the Minkowski extension from the base τ¹ provides 3+1-dimensional spacetime with the correct signature.
Chapter 76 (“E₁ Complete”) synthesises: E₁ is not a model of physics—it is the structural layer where physics becomes definable. Export contracts to Books IV–V are formalised, and the transition to E₂ is previewed.
Chapter 77 (“The Temporal-Spatial Decomposition”) unpacks the base τ¹ direction as the temporal axis and the fiber T² directions as spatial, completing the 3+1 signature derivation.
Scope throughout: τ-effective (Chapters 74–75, 77); τ-effective + metaphorical (Chapter 76, closing reflection).
