FUURAA thesis
A deployment claim is credible only when its measurement boundary, denominator and failure record are visible.
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.
Failure taxonomy
Separate robot, tool, perception, material, upstream, downstream, safety and operator causes without double counting.
Traceability
Link software, recipe, tool, calibration, product lot, operator and environmental state to every material result.
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
Is the denominator cycles, attempted parts or accepted parts?
- 02
Are manual resets and discarded trials included?
- 03
Can another team reproduce the measurement procedure?
- 04
What changed between the best demonstration and the reported average?
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.

Evidence package 1
Versioned test protocol and raw event log
- 02
Evidence package 2
Failure taxonomy with time, cause, owner and disposition
- 03
Evidence package 3
Calibration, software and configuration evidence for every run
Scope boundary
State what this evidence still cannot be generalised to.
- 01
A clean video, best-case cycle or unversioned spreadsheet cannot establish repeatable production performance.
- 02
This is an engineering reading and decision framework; it does not replace application-specific risk assessment, conformity work, procurement acceptance or professional advice.
