State-Space Map
AT-0059 → AT-0072. Two states can pass the same identity test and still have no allowed route between them. This lab maps the valid regions, the islands, the corridors and the barriers — and gates every candidate before it is allowed to mean anything.
x₁ ≡ x₂ ⟺ ‖Q(x₁) − Q(x₂)‖ / ‖Q₀‖ ≤ tol, Q = (x̄, σ², ‖x‖)
