 287/-! ## Bridge Lemmas: CPM Constants from RS Invariants
 288
 289These lemmas explicitly connect CPM constants to Recognition Science
 290invariants, providing the formal bridge between the abstract CPM
 291framework and the RS derivations. -/

 295/-- C_proj = 2 follows from the J-cost second derivative normalization.
 296
 297The Hermitian rank-one bound ‖Pψ‖² ≤ C_proj · ‖ψ‖² has optimal constant
 298C_proj = 2 when the projection is normalized so that J''(1) = 1 in
 299log-coordinates. This is the content of `RS.Jcost_log_second_deriv_normalized`. -/
