Matter–Antimatter Asymmetry as the Unique Admissible Reconstruction of Persistent Cosmological Identity

Overview

This paper develops an AASC account of matter–antimatter asymmetry as a structural reconstruction theorem rather than a new baryogenesis mechanism. It does not alter Standard Model dynamics, derive the baryon-to-photon ratio, compute CP-sector numerical values, or select a specific physical mechanism such as leptogenesis or electroweak baryogenesis.

The central question is prior to mechanism-building: under what conditions can a cosmological history support persistent material reference after irreversible loss of the correlations needed to transport exact matter–antimatter exchangeability?

Central Result

The paper proves that, on a fixed cosmological material-reference scope, exact matter–antimatter exchangeability cannot serve as a late same-history identity symmetry on the burden-realizing support once genuine retrieval-irreversibility has removed the exchangeability preservation certificate.

The resulting structural object is a boundary-fixed admissible surplus reconstruction class, carried by persistent anchor witnesses in the post-irreversible anchor quotient.

Main Contributions

• Defines the fixed reconstruction category for persistent material-reference histories.

• Separates global exchange-totalization failure, burden-restricted obstruction, and burden-wide lower-bound support.

• Shows that burden-restricted exchange obstruction gives nonempty burden-relevant witness support.

• Shows that, under burden-wide exchange non-transportability, the witness rank is bounded below by the declared material-reference burden (\rho_S).

• Establishes sign fixation on sign-coherent material-standing scopes.

• Distinguishes the structural surplus reconstruction class from numerical baryon abundance.

• Reinterprets baryogenesis mechanisms as downstream physical realizations of a prior admissibility constraint.

Relation to Standard Baryogenesis

The paper is compatible with standard baryogenesis programs. Freeze-out, electroweak baryogenesis, leptogenesis, sphaleron conversion, inflationary dilution, reheating, and entropy-producing dispersal may generate, transfer, protect, dilute, or convert projected particle-number asymmetry inside declared physical models.

Their AASC status is that they occupy or witness the already-forced admissible surplus reconstruction class. They do not generate the admissibility of that class by later redescription.

Scope and Nonclaims

The paper does not claim to derive:

• the baryon-to-photon ratio;

• the observed numerical baryon abundance;

• CP phase values;

• CKM or PMNS coordinates;

• a specific baryogenesis model;

• a privileged quark sector;

• a violation of microscopic CPT symmetry.

Its result is a fixed-domain structural theorem concerning exchangeability non-transportability, persistent material-reference reconstruction, and boundary-fixed surplus-class admissibility.
