VAULT v1.1 — A Bounded, Route-Certified Architecture for Safe, Reusable Space Travel

VAULT v1.1 is a closed, operational architecture for space travel that replaces vehicle-centric survivability with route certification inside bounded kinematic regimes. The system introduces an operational “envelope” defining safe coherence domains, mandatory early-exit (rollback) authority to prevent runaway failure, and a transport layer based on certified travel corridors (“shuttleways”). This work demonstrates that dominant spaceflight hazards—particularly dust, cumulative wear, and navigation instability—can be rendered bounded and therefore engineerable. Under VAULT v1.1, aborts are treated as safety successes, reuse becomes a reliability multiplier, and mission success moves from exploratory (~4–5) to infrastructure-grade (~8.5–9+, with operational mode). The framework is intended as a foundational reference for safe, repeatable, high-reliability space transport and is presented as a complete, non-exploratory architecture. Execution-layer details, partner interfaces, and deployment artifacts are intentionally excluded.
