That sandwich, and the apparatus that makes the two sides talk to each other, is the actual contribution.\n\nWhat is new is not the individual tools. Linear DPO track spans, maximal stable subobjects, Yoneda/Kan reification obstructions, quotient-norm duality, Kronecker–Weyl, Abel means, and Weil/Deligne point counts are standard and cited. The paper’s work is the packaging: a realization–error datum that keeps occurrence structure until after error extraction; pathwise intact domains composed with ordered-monoid certificates; discrete and fibrational quantitative reflection; compact-group interpolation with dual formula; and Abel/Mellin/generating-function transfers that feed the lower endpoint, including a clean finite-field curve application that separates the coefficient lower bound from the exact limsup of the trigonometric realization.\n\nThe core categorical lemmas look solid on a read-through—maximal transportable region, path track composition, track pseudofunctor on independence diamonds, discrete Ran = fiber inf, fibrational reduction, quotient and compact-group duals. Circularity is low: U and Q are built from different data. The analytic guards are stated honestly (interior agreement for boundary poles; soundness on actual domains; fibration for the strict-fiber formula).\n\nSoft spots, in proportion: the manuscript is long and synthetic rather than paradigm-shifting; several analytic steps are compressed; and the author declares ChatGPT generated parts of the proofs. That is real verification debt for a pure-math paper with no formalization. Significance is moderate—useful inside categorical rewriting and quantitative error analysis, not a field-wide reset.\n\nThis is for people who already care about adhesive rewriting, proof identity, or tail bounds from coefficients. A serious editor should send it to referees rather than desk-reject; the contribution is accept-shaped if the proofs hold under independent check. I would bring selected sections to reading group and might cite the sandwich and the compact-orbit transfer if I needed that language.

This paper argues that those distinctions matter for error bounds, so error must be extracted from the chosen realization before collapsing to behavior. The magnitude of that error is then sandwiched: an upper certificate built from guarded local estimates along the realization’s path, and a lower bound forced solely by what is observed. For linear double-pushout rewriting the paper identifies the greatest subobject carried intact through a step or path, so certificates compose only where occurrences survive. For linear observations the lower bound becomes a quotient norm, and via compact-group interpolation and Abel transfer it yields concrete tail lower bounds for Mellin data, generating functions, and normalized point-count errors of curves over finite fields.","feed_headline":"Error sits between path certificates and behavior-only floors","feed_subtitle":"Extract error before collapsing to behavior;
