Energy Bookkeeping of a Transit in the Aldred Frame: What a Passage Costs and Where the Energy Goes

Energy accounting of one transit event in Einstein-Cartan spin-torsion gravity in the frame of the Aldred Limit (rho_A = 9.72e54 g/cm^3). For a throat of radius r_t held at density f*rho_A: the energy density is exactly the fraction f of rho_A c^2 = 8.74e74 J/m^3; the formation energy of a one-metre throat at f = 0.99 is 3.62e75 J (2.03e28 solar masses equivalent; 3.00e41 years of solar output); on closure the total energy is returned in full (the torsion term is not a sink) via bounce re-expansion, but the partition between re-expansion, radiation, and any remnant is not fixed by the frame and is printed as an open term, as is the holding power, for which the frame's algebraic torsion contains no term. Cost scales as E ~ f r_t^3 and linearly in payload mass at 8.65e71 J/kg (f = 0.99, payload at water density). All figures are model calculations within the stated frame: SIMULATED, NOT MEASURED; no hardware exists.
