FUURAA thesis
A capability claim is only meaningful inside the conditions in which it was repeatedly measured.
Engineering map
Turn the title into engineering objects that can be observed, measured and reviewed.
Each layer states the boundary to establish and the evidence needed for the next decision.
Task envelope
Bound objects, loads, tools, timing and quality.
Human envelope
State training, proximity, intervention and bystanders.
Verification questions
Write the questions first, then decide whether a demo, test, pilot or operating record can answer them.
Each question needs an object, conditions, denominator, threshold and accountable decision owner.
- 01
Which conditions were varied?
- 02
Which limits trigger stop or assistance?
- 03
Was the complete machine tested?
- 04
What invalidates transfer to a new site?
Evidence to preserve
Enable the next reader to reconstruct conditions, results, failures and the decision.
A conclusion alone loses reviewability; raw records, configuration and exclusions matter too.

Scope boundary
State what this evidence still cannot be generalised to.
- 01
Passing a locomotion test does not validate safety or every application.
- 02
This is an engineering reading and decision framework; it does not replace application-specific risk assessment, conformity work, procurement acceptance or professional advice.
