Kink-Safe ρ Bridge, Normalized Slope Gate, and Component Taylor Remainder: Rejecting the Raw Hausdorff Bridge, Correcting the C² Curvature Assumption, and Reducing the Remaining Tube Closure to an Envelope/Topology Remainder

Withdraws the C² curvature bridge of MCC-OE-18; records the raw ρ-Hausdorff bridge as REJECTED (0 of 10,485,760 pass); replaces them by a normalized Q = (A − A0)/ρ² Lipschitz gate (L_Q↓ < 63,932.77) plus a component Taylor remainder (≤ 18.3136 ρ³).
