GRSC Reconstruction Paper: The Quantized Real Domain and a Finitely Readable Background

This standalone reconstruction paper follows the completed arithmetic-closure judgement summarized in GRSC Papers16-62. It introduces the quantized real domain as a finitely readable background carrying a minimal reading unit, finite windows, error and boundary ledgers, obstruction ledgers, certificate levels, and an algebraic-compatibility interface. The paper develops the significance of this background for modern arithmetic and gives renewed interface meanings to Gaussian integers, quadratic forms, residue and reciprocity, and periodicity.
