Astrosynthesis Vol. III — The ICHTB Model — Inverse Heisenberg Cartesian Tensor BoxVolume III of the Astrosynthesis series. The ICHTB (Inverse Heisenberg Cartesian Tensor Box — also referred to as the Heisenberg Inverse Cartesian Tensor Box, both terms are fully fungible) is the complete working model of recursive field emergence. The cube whose six faces are labeled not by coordinates but by recursive collapse operators. Space is not pre-given — it emerges from tension resolution. The center is the imaginary scalar anchor i₀ ∈ ℂ, a recursion seed with no location, only potential.The six zones: Δ₁ (+Y Forward Tension ∇Φ) · Δ₂ (−Y Memory Plane ∇×F) · Δ₃ (+X Expansion +∇²Φ) · Δ₄ (−X Compression −∇²Φ) · Δ₅ (+Z Apex ∂Φ/∂t) · Δ₆ (−Z Core Φ=i₀).Master equation: ∂Φ/∂t = D∇ᵢ(Mⁱʲ∇ⱼΦ) − ΛMⁱʲ∇ᵢΦ∇ⱼΦ + γΦ³ − κΦHat-counting address system: every point in the box has a unique address (k, u, v, h) where k=face/zone, u,v=face grid coordinates, h=depth toward i₀, ℋₖ(u,v)=hat count.Part of the Astrosynthesis: Excitations and Expressions of Emergence series.Vol. I — Excitations and Expressions of Emergence: https://doi.org/10.5281/zenodo.19328544Vol. II — The ICHTB Geometry of Pre-Emergence: https://doi.org/10.5281/zenodo.19363000Repository: https://gitlab.com/intent-tensor-theory.com-group/git_0.0_astrosynthesis_excitations_and_expressions_of_emergenceWebsite: https://intent-tensor-theory.com · Model: https://intent-tensor-theory.com/astrosynthesis/vol-II/
