Information-Based Dark Sector Model: A Consistent Effective-Field-Theory Formulation and Cosmological Consistency Conditions

Version 2.0 contains a substantial reformulation of the model. The canonical scalar field is separated from the conformal factor to ensure dimensional consistency; the local entanglement-entropy density is replaced by a covariantly defined effective information-sector operator; the early-dark-energy scale is recalculated using the Hubble rate at the transition redshift; and the matter-like oscillatory phase is analysed explicitly. The revised manuscript also identifies a consistency limitation of the minimal one-field construction: the EDE remnant alone cannot reproduce the full present dark-matter abundance without an additional energy-transfer or production mechanism. Microscopic claims concerning the Weyl-anomaly coefficient are correspondingly reformulated as open matching questions rather than first-principles derivations.
