Finite Information Throughput and Effective Density Saturation: An Interpretive Note on the Conceptual Vocabulary of the Effective Saturation Papers

This preprint presents an interpretive note for the effective saturation program. It does not derive the effective closures used in the companion papers and does not claim a completed theory of quantum gravity. Instead, it proposes a conceptual vocabulary in which effective density saturation may be read as a local finite-throughput or finite-compression principle, formulated through a bound of the form dI/(dt dV) ≤ ρ_sat c²/ħ. The note maps this interpretive language onto three narrower effective studies: an analytical black-hole interior model, a numerical collapse companion, and a minimal bounce cosmology. It distinguishes explicitly between heuristic postulates, effective-level readings, and conjectural interpretations, and should be read as a conceptual prelude rather than as a source of new physical results.
