Statement
Century-scale process equipment must itself be repaired using locally available processes and knowledge.
Evidence dimensions
- Basis
- normative
- Readiness
- breakthrough dependent
- Confidence
- supported
Assessment rationale
Current maintainability practice requires access, fault isolation, restoration, test equipment, documentation, skills, and logistics. Permanent loss of an external supply chain extends those requirements to the process equipment, software, metrology, and knowledge that sustain production; the cited portfolio does not demonstrate that recursion.

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 factory-reproduction matrix plus repeated demonstrations that repair machine tools, furnaces, joining systems, controls, process sensors, and metrology from declared local processes across expert turnover would raise readiness; irreproducible equipment would define a finite mission bound.
