Exact reverse-engineering
Local triad: I=(1−cos θ)/2, O=(1+cos θ)/2, ℛ=sin θ
Whole triad: IH=(1−cos φ)/2, OH=(1+cos φ)/2, ℛH=sin φ
T(XL,XH)=((A+a(OL−IL))(OH−IH), (A+a(OL−IL))ℛH, aℛL)
Implicit check: (√(x²+y²)−A)²+z²=a²
Under the displayed chart assumptions, each ring-torus address is exactly decodable into a local normalized triadic coordinate and a whole-level normalized triadic coordinate. The selected N layers are delayed instances of the candidate local operator; their weighted circular closure supplies Θ, while φ carries the relation of that closure to the whole.
The torus is a many-to-one two-phase projection of a larger state containing N phases, N+1 residue states, parameter values, and delayed system history. A return to the same torus coordinates does not imply return to the same complete model-state.
