Statement
Require full-scale human-in-the-loop mockups, diverse-body accessibility review, fire/refuge tests, and long-duration rotating-environment evidence.
Evidence dimensions
- Basis
- normative
- Readiness
- early research
- Confidence
- supported
Assessment rationale
Current human-system, artificial-gravity, fire-safety, accessibility, and rights evidence supports representative human-in-the-loop testing before exposing a diverse civil population to an irreversible habitat. No cited program validates the complete gate at full scale, across disabilities and life stages, in a rotating long-duration environment.

Assumptions and limits
The assessment applies to this bounded statement and the cited source scopes. A source can support one relationship without validating a generation ship, and an editorial grade does not substitute for independent review or representative demonstration.
What would change this conclusion?
A disabled-led, independently reviewed acceptance framework with stronger predictive validity, or full-scale demonstrations covering diverse bodies, refuge and fire faults, rotating exposure, maintenance, evacuation, and long-duration outcomes, could revise this gate.
