Described Twice? A finite audit of a possible gravity–measurement seam

A finite, exact audit of a possible gravity–measurement interface. The manuscript distinguishes algebraic consistency within a declared model from the additional premises needed for physical interpretation. It compares two conditional source rules using a common local tomography instrument and identifies an exact threshold under independent local dephasing. Version 0.5: reconciles the manuscript with CANON records through INT97R (e2503b3d), interpreted with DRIFT K16; corrects the partial-transpose determinant and dephasing threshold; clarifies history currents, event counting versus billing, normalization inputs, conditional transfer and repeated pointer updates. It improves the graduate-level exposition, verifies and corrects references, and adds two TikZ diagrams. The deposit includes the revised PDF and LaTeX/BibTeX sources, both unchanged earlier certificate archives, a new CANON supplement with 278 verified source files and SHA-256 manifests, and independent SymPy checks of the manuscript calculations. The supplement preserves evidence and frozen source snapshots; it is not a complete historical Git environment, and the editorial review did not replay every certificate. The results do not select a universal billing law, absolute normalization, physical clock, continuum limit, or completed gravity–measurement unification. The INT96R parent ruling at 4ecb7327 contributes no new result credit.
