Statement
A worldship would combine a pressure vessel, rotating machine, city, hospital, school, farm, factory, and refuge; this bounded standards survey did not identify one standard covering that combination.

Assessment rationale
The bounded standards survey found NASA and ECSS documents that separately govern human factors, pressure and fracture control, materials, fire, atmosphere, operations, and pressurized hardware. Their documented scopes, exclusions, and interfaces do not establish one qualified standard for a rotating, self-maintaining civil settlement that also functions as housing, healthcare, education, agriculture, industry, and refuge. This is a dated search conclusion, not proof of universal absence.

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?
An independently maintained standard that explicitly integrates rotating pressure structures, diverse civil habitability, healthcare, agriculture, industry, refuge, inspection, repair, and multidecade lifecycle assurance would narrow or supersede this claim; a collection of separately applicable crew standards would not.
