The bundle contains the canonical record plus signed events. A mirror can host it anywhere and recompute the same current state with the deterministic merge algorithm.

Claims

C1strongest claim

We mathematically prove the consistency of the Rankzzy for any admissible configuration selected by stakeholders. The evaluation conducted indicates a reduced computational cost in large-scale value-based decision-making problems and a strong rank performance regarding existing approaches when employing the aggregation via Pythagorean means.

C2weakest assumption

That the fuzzy domain of decision variables together with the score function can faithfully encode both quantitative and qualitative criteria without loss of information or introduction of new bias that would invalidate the unweighted generalization.

C3one line summary

FUW-VBDM reframes value-based decision making as unweighted optimization over a fuzzy score domain, solved via the Rankzzy method whose consistency is proven for any admissible stakeholder configuration, with lower computational cost than weighted baselines.
