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 long-duration independently reviewed space habitat that regenerates a nutritionally complete, safe, culturally adaptable diet for representative residents would change the claim.
