Required inputs
Named uncertainty components
Common output unit
Dependence assumptions
Coverage policy
Ordered execution
Work the protocol
- 1
Convert components to one unit.
- 2
Separate bounded bias from standard uncertainty.
- 3
State whether components are independent.
- 4
Use root-sum-square only for independent standard components.
- 5
Compare the result with every relevant decision boundary.
Outputs
- Component table
- Combined uncertainty
- Boundary-stability decisions
Done only when
- Every component has provenance.
- Combination assumptions are stated.
- Unstable categorical outputs are withheld.
Fail closed
Refusal conditions
- Unlike units are combined.
- Correlated terms are treated as independent.
- Unknown uncertainty is entered as zero.

Uncertainty: The receipt demonstrates the declared combination rule; correlated, bounded, or unknown components require a different model.
