Case-II raw rounded transport without the outer-endpoint Claim 14.6(i) interface #
The three variants below replace the overstrong quotient Claim-14.6(i) premise on the outer source interval by the only consequence used by the rounded assembly: coordinate-wise transport of the quotient error envelope.
Double-rounded sharp Case-II endpoint transport.
The natural cutoffs are y = ceil(D^(1/3)) and z = ceil(D^(1/s)).
Dimension-one transport and the logarithmic ratio are carried out only at the
exact real roots. The two Euler products are then returned exactly to their
natural-ceiling cutoffs; no equality between a cast natural cutoff and a real
root is assumed.
Direct double-rounded concrete relative Case-II theorem.
The Case-I induction/source packet is consumed by the sharp natural-ceiling
endpoint theorem. The resulting transport remainder is absorbed by the fixed
positive-Δ packet, and the packet is then contracted to the concrete relative
coefficient. In particular, the public interface exposes neither a raw
endpoint inequality nor an abstract endpoint-error premise.
