The Aggregated Ledger: Many-Body Statistical Mechanics and the Emergence of Bulk Thermodynamics (Paper 12 Cheat Sheet, from the Departure From the Photon Baseline series)

A 14-page simplified companion guide to Paper 12 (The Aggregated Ledger) in the Departure From the Photon Baseline series by Dervis Kadunic. Designed to be read before the main paper, it presents the core argument in plain language with visual diagrams, covering single-ledger crowd accounting, declared-window frequency counting, population temperature as an exact counted fraction, the counting-based thermodynamic arrow, equilibrium criteria, the named open gap between \tau and \Omega, falsification conditions (C23–C33), and the paper's 19-script verification and Crucible trial record.
