Statement
This English-language foundation review found no public evidence of an integrated human habitat demonstrating multigenerational material closure and recovery from severe ecological faults; the search was not systematic.
Evidence dimensions
- Basis
- observed
- Readiness
- no known path
- Confidence
- strong
Assessment rationale
The bounded English-language review found high water recovery, regenerative compartments, enclosed-facility experiments, and a 370-day four-person Lunar Palace experiment with maintenance and recorded failures. None demonstrates an inhabited ecology across generations with complete material accounting and recovery from severe coupled faults; because the search was not systematic, the conclusion is explicitly limited to the reviewed public record.

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 systematic multilingual review finding a public multigenerational demonstration—or an independently observed habitat that accounts for every essential element and recovers from representative ecological, hardware, microbial, and governance faults—would reverse this finding.
