A Bound for the Boundary: The Cosmic Entropy Count Paper #54 Owes, Stated as a Bounding Statement with Its Premises in Full

Discharges item D-041-080-23 (paper #54, The Arrow Census, Entry 2) at its priced shape: a bounding statement for the cosmic entropy count with its premise set stated in full (seven labelled premises: CMB temperature 2.7255 K and comoving radius 46.5 Glyr as literature inputs, the blackbody entropy per photon 3.6016 gated from constants, the neutrino share 0.954545, adiabatic conservation with a stated factor-10 headroom, the Egan-Lineweaver-class present-day interval 1e104-1e105 as a literature premise, and an early-slice baryon allowance). Gate first reproduces paper #54's exhibits from the recovered copies (Entry 2's price line verbatim in original and build; 9 entries; 4 separable; 3 boundary postulates; 4 degenerate pairs; 4.8e8 GeV three times per version; GRW values; 11 of 11; producing-count 0) and paper #216 sec.4's ledger digit-for-digit (5.88237e9 and 1.14998e10 against printed 5.9e9 and 11.5e9). Derived bounds: early-slice entropy S_early < 1.1e91 k_B in today's comoving observable volume; S_early/S_max < 1e-32 against S_max = 2.32748e123; entropy growth since the slice > 9e12. The #216 ledger is spent only as a cross-check (agreement 1.03136e90 vs 1.03113e90); the total count, early-slice bound, maximum ratio, and growth factor are absent from #216, answering CREM13 ground (ii), and the printed premise set answers ground (i) on the Wave 19 recovery ruling's admissible form; the struck absence ground is not re-spent. Disposition: item closed in full at its bounding scope. Grade EXTENSION (components are world prior art spent as premises; no FIRST claimed). Quantum gravity NOT SOLVED; vacuum catastrophe NOT SOLVED.
