 223  /-- Map RS complexity to Clay's Turing model -/
 224  to_clay : RecognitionComplete → (ℕ → ℕ)
 225  /-- Clay sees only Tc, missing Tr -/
 226  projection : ∀ RC, to_clay RC = RC.Tc
 227  /-- This makes P vs NP ill-posed in Clay's framework -/
 228  ill_posed : ∀ RC, RC.Tc ≠ RC.Tr →
 229    -- Clay cannot distinguish the full complexity
 230    to_clay RC = RC.Tc
