Paper Step 4(A): the residual endpoint-pattern producer

This file is the final assembly of the literal four-endpoint argument in paper §4.2. The two signed half transforms are completed before a norm is taken. Their common nested endpoint density is then passed, unchanged, through the existing grouped majorant, complete nested run, and weighted exit.

The public residual Step 4(A) input, obtained only after enlarging the literal four-endpoint case product to the paper's uniform eps ^ (-8) budget.
