Design Blueprint: Fifth-Coordinate Transit Pod: Timing and Energy Budget for an Earth-Moon Crossing Under the Transit Law

Design blueprint derived from the source paper (DOI 10.5281/zenodo.24123501): The device is a crewed transit pod of one to five tonnes that crosses between Earth and Moon not by thrust along the ordinary path but by a brief excursion through a fifth coordinate, entering and leaving ordinary space at powered gate structures at each end. Status: DESIGN BLUEPRINT — SIMULATED, NOT MEASURED — NOT BUILT. All numbers are simulated values from the source paper's computation, deposited with this blueprint as compute.py and results.json. Computed verdict: impractical as specified — a 1,000 kg pod requires 2,440,482.665 TJ for a single crossing at the stated coupling efficiency.
