This paper develops a finite readout and matching protocol for the compact fiber F = Z₄^m₁ × Z₄^m₂ × Z₈ᵉ. The first part formalizes the compact fiber as a finite character/readout object by passing to its character group F̂ = Hom (F, U (1) ). The two Z₄ factors define finite magnetic character sectors, while the Z₈ factor defines the finite electric character sector. The degree-two cover Z₈ → Z₄ identifies direct magnetic-base compatibility with even electric characters and gives odd electric characters a deck-parity interpretation. The main finite-layer result is the Character-Readout Classification Theorem. It shows that recurring compact-fiber factors such as 1/8, 1/4, 7/8, 1/32, and 128 arise as projections, complements, product-sector resolutions, or full character counts. The cover-mediated factor 1/16 is fixed once a readout is assigned to the degree-two electric cover class. The paper also proves a finite character conservation rule for closed internal finite-sector couplings and recasts the radiation-paper OAM parity rule as a cover-compatibility statement. The second part applies the same status discipline to an elementary natural-unit mass-to-energy bridge. The bridge is represented as a single source-to-target traversal from a completed two-dimensional secondary-mass source to an energy/readout target. This fixes the typed package s = m + e_∂. Using the Larson–Nehru interregional and secondary-mass bridge-layer rules, the electric boundary contribution is reconstructed as e_∂ = e = (1/|F̂|) (1/9) (2/3) = 1/1728, so the admissible elementary matching package is s = m + e. The result is a no-retuning audit framework: a proposed factor must be a defined finite-character operation, a cover-conditional readout, a theorem-grade bridge result under stated premises, or an open term. Competing packages such as m, m + 2e + C, e − c, and e − C are rejected by readout class rather than by numerical fit.
