\begin{tablenotes}\footnotesize\item Lot area, storeys, physical link and building genre are complete for more than 90\% of headline sales in every year (results/profile/completeness\_by\_year.csv). The provider's building style (12\% present in January 2021, 87\% in January 2025) is excluded from every model. New constructions (sold in the roll's construction year) fall to zero in 2025--2026 because the roll vintage lags construction.\end{tablenotes}
