Duplicate ZIP×district relationships use MAX(area_ratio), never SUM(area_ratio). Split ZIPs are preserved. Additive ZIP values are allocated by area_ratio and summed; district ratios are recomputed from the corrected components. ZIP/ZCTA desert classification is direct Texas-compatible evidence. House district ratios are legislative context estimates.
