formal statement (Lean)

  75structure RefinementConverges (sys : DirectedRefinement C) : Prop where
  76  eventually_separates : ∀ c₁ c₂ : C,
  77    (∀ i, Indistinguishable (sys.recognizer i) c₁ c₂) → c₁ = c₂

  81/-- U3: Dimension invariance under refinement choice.
  82Two directed refinement systems that both converge and both admit
  83a common separation count produce the same dimension.
  84(The full statement requires chart-atlas infrastructure; here we
  85record it as a property of the separating-recognizer count.) -/
