The ramp comparison is not a fifth closure

If an enlarged ramp comparison admitted the excluded edge vector and all its real multiples while preserving the old response, its tested discrepancy would have an affine real-surjective orbit. The same elementary orbit proof would apply to that new comparison. It would not identify its edge integral with $c_{\epsilon }$, nor change the frozen ramp algebra.

An already invariant real ramp coefficient, if supplied as input, can be encoded and read with equal outputs on equal invariant values. That preserves an upstream identity; it does not prove the ramp theorem, acquire the coefficient, or repair the convolution.

Retaining the cited X-A-ST through X-H-ST interfaces adds no operation changing the frozen convolution contract. Their tree, free-BRST, relative-BV, and supplied-report statements are not a new covariance proof for $w^{\mu }$ XAST,STRecords,XGST,XHST. This is a prescription-level non-identification, not a claim to have scanned every possible manuscript or excluded every future changed model.
