Chapter 56: The Complete Constants Ledger and the G–α Bridge

Two books, 180 chapters, and one master constant. This chapter assembles every physical constant derived from ι_τ = 2/(π + e) across Books IV and V into a single ledger, demonstrates the unique G–α bridge that connects gravity to electromagnetism without free parameters, and presents the four-layer SI calibration cascade by which one algebraic constant and one measurement determine all of physics. Zero free parameters, zero retroactive fits, and zero scope inflation.
