Constraint-First Geometry: a GUT / Theory-of-Everything candidate series

A constraint-first derivation program in fundamental physics: one frozen thirteen-dimensional internal geometry, fed four measured anchors, used to read the gauge sector and nineteen-plus flavor observables off the geometry - including the count of three chiral families as a topological integer that cannot be continuously tuned. Includes five manuscripts (TOE capstone, GUT, Forces, Quantum, Particles), a reproducibility script bundle, supporting method/defense documents, a completeness audit, and eight worked-example notes that reduce the geometry to four dimensions and reproduce known physics (gravitational light-bending, the hydrogen spectrum, the muon-decay law, and more). NOT peer-reviewed; in submission to Physical Review D and Foundations of Physics. A front door for external review: every open gap is marked with a named falsifier, and the one place the deepest idea failed (the cosmological constant) is published as a failure.
