Uniqueness score is an ML-derived text measure, standardised; mapped to taxonomy multimodal_embedding (closest H leaf; text-only) - flag for review. Table 4 columns 1 and 5 and Table 5 column 1 repeat Table 3 estimates and were not duplicated; Table 5 column 5 (listing-sale price spread) excluded; Table 7 (year FE index) excluded. Stars: *** p<0.01, ** p<0.05, * p<0.1."
