Quantum Darwinism as Syndrome Broadcast: A Finite-QEC Reconstruction of Objective Records

Abstract

Why does the everyday world look objective — the same for every observer? Quantum Darwinism already answers that classical facts are information about einselected pointer states copied redundantly into many fragments of the environment; this note reconstructs that mechanism from the single premise of stable local records. Repeatable records force orthogonal sectors; finite noise forces an error-correcting code; syndrome extraction selects the pointer basis; syndrome fan-out supplies the redundant environmental copies; and finite, reusable registers make the irreversible part of measurement a Landauer reset. In the ideal syndrome-broadcast limit the characteristic Darwinist plateau is immediate — any non-empty proper fragment of the environment carries the full classical syndrome entropy, while the extra quantum phase information lives only in the whole. Deliberately modest: it does not replace decoherence theory, derive the Born rule, or solve the measurement problem; it closes by mapping the programme's older geometry-first language (cells, strain, defects) onto the finite-QEC vocabulary (code, syndrome, ledger).
