Terrain
Bound slopes, steps, gaps, grating, loose media, friction and structural stability.

FUURAA thesis
Legged capability is always conditional on an operational envelope.
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.
Environment
Bound light, rain, dust, temperature, gas and radio conditions.
Task
Attach speed, payload pose, sensing distance and contact demand to each route segment.
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
What conditions are explicitly in scope?
- 02
What forces slow, stop or abort?
- 03
How is surface change detected?
- 04
Which evidence must be repeated after change?
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.

Go/no-go and change-control record
Scope boundary
State what this evidence still cannot be generalised to.
- 01
Evidence from a prepared course, dry day or unloaded robot does not silently transfer to another envelope.
- 02
This is an engineering reading and decision framework; it does not replace application-specific risk assessment, conformity work, procurement acceptance or professional advice.
