This page is the foundation of the series: the complete axiomatic content, stated once, so that everything else can be defended as consequence. Three postulates suffice. P1 (the Algebra): all that exists is quaternion-valued — octonion-valued behind the colour door, time enters on the real axis as W = iτ, and what is observed is the three-dimensional projection of quaternionic motion. P2 (the Geometry): there is no force, only curvature — gravity, weak, and strong are one spacetime’s curvature at three winding radii; each world, of constant curvature, is bounded by two limits, a horizon and a drain; matter is condensed space, and curvature is carried at every scale by winding, each winding radius R constituting a living space with door ħc/R and seal e^(−r/R). P3 (Eternity): the universe is static and eternal. From these follow, as theorems: the Lorentz signature; the weak gauge group and its handedness; the existence of fermions; quantization as winding closure; the family law T·R = ħc/2πk_B binding every scale; the conservation ledgers; the temperature history T(z) = T₀(1+z); and the unique line element of the cosmology. The final section asks whether this is yet a general field theory — answering the honest not yet — and names the engine still owed: the Clausius relation δQ = T dS imposed on every seal of every rung, from which the field equations must follow.
