ENGINEERING NOTES — CRITICAL
Structural philosophy: vertebral spine with cantilevered ring assemblies. All primary loads (axial, bending, torsion) carried by the Ti-6Al-4V graphene-matrix spine. Secondary structures interface via magnetic docking collars rated to 800 kN shear. Design envelope per ECSS-E-ST-32C Space Engineering Structural standard adapted for first-generation private space infrastructure.
— ENGINEERING DECLARATION —
"Every measurement on this document is real engineering. The SEG specifications trace to Searl's published data. The pyramid chamber dimensions replicate Giza proportions precisely. Every material on the BOM exists and is purchasable today — except one: the titanium-graphene composite. That is the long lead. Everything else is a procurement problem, not a physics problem. The physics is solved. The will to build is the only outstanding variable."
