Orbit architecture

Applying ρ to the non-ω generators produces exactly four generated rays O_α, O_π, O_γ, O_η together with the singleton/fixed boundary ω. K5 supplies the diagonal discipline: no finite iteration on a non-ω generator reaches ω. The result is a linear-symbolic universe with four finite-directional channels and one boundary absorber: enough generated directionality to avoid under-generation, but enough diagonal discipline to prevent unrestricted self-collapse. The diagonal discipline maps structurally onto Girard’s !-free linear logic.
