Statement
Demonstrate navigation and archive recovery without current experts, cloud services, vendor activation, or a single surviving medium.
Evidence dimensions
- Basis
- normative
- Readiness
- operational
- Confidence
- supported
Assessment rationale
This is an evidence-admission and resilience test rather than a prediction. Current navigation software archives, autonomous flight demonstrations, systems-engineering verification practice, and archival standards make the test implementable, while no cited program demonstrates its full duration and independence boundary.

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 stronger independently reviewed recovery standard that preserves state uncertainty, calibration, provenance, secure control, media diversity, succession, and offline rebuildability could replace this gate; vendor continuity alone would not satisfy it.
