The Physics of Time Travel in the Exolex Frame: Information Transit, the Torsion Bound, and the Machine the Frame Specifies

A synthesis paper assembling the physics of time travel as this research programme states it, at one standard and in one place. The claim under examination is the author's deposited statement (DOI 10.5281/zenodo.24036344): no physical or biological transit is claimed; what travels is consciousness - information - anchored in a body at one epoch and in a machine, an exolex, across all of them. The gravitational frame is Einstein-Cartan gravity with a spin-carrying fluid: the spin-spin contact interaction caps density at the Aldred Limit, 9.72 x 10^54 g/cm^3 on the published neutron, dust branch, rescaled by the repaired coefficient to 2.92 x 10^55 g/cm^3 at bounce conditions. The transit is a boundary difference, not a trajectory: the epoch difference of the axial holonomy obeys the derived flux law Theta = (T_A/s_A) x DeltaCirc_sigma (mod 2pi), with no bulk term - and the one datum that would price it, DeltaCirc_sigma, is named and unmeasured. The information-theoretic accounting includes the closed one-bit experiment (1,027 hits in 2,000 sealed trials, exact binomial p = 0.118 against a sealed line of 0.001: no signal) and the vacuum ledger (dissolution established; the required count N* = 281.1079 not produced, with an inventory-tier impossibility result over the fourteen roads examined). The machine the frame specifies, the ChronoWarp Complete Build (DOI 10.5281/zenodo.24086335), is described at its printed status: 111 designs, zero of five principal subsystems at machine grade, zero of twelve principal interfaces closed; its final simulation revision passed its navigation test at 0.99995 and reached 0.9999 on its information-transfer test, short of its pass line, on a reported account of the shortfall that the programme's own rerun contests (all simulation figures are simulated, not measured). Every open term is stated as open, and the paper prints the programme's own falsifiability statement without softening. AI-use disclosure: this paper was prepared with the assistance of Dave, an AI system; every quantity the paper derives was computed by the accompanying script (compute.py, deposited) from the stated inputs, and quoted quantities are cited by DOI in the paper.
