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 show that incorporating publicly available Census data into assessment models - a feasible reform in most counties - would significantly improve both accuracy and fairness relative to status quo assessments.

C2weakest assumption

That the simulated assessment models and domain-relevant fairness metrics accurately reflect real-world implementation effects and capture the intended notions of fairness in tax burdens.

C3one line summary

In U.S. property tax assessments, accuracy and fairness improve together with better models and data, rather than trading off against each other.
