Validation gate: all checks passed (see data-raw/refresh_summary.md). - zip_code_db: 41,877 -> 42,725 rows; 0 removed. Every 2020 Census ZCTA now present (fixes #25 97003 and the territory ZCTAs behind #19), 787 Military ZIPs added (new zipcode_type value), curated USPS-only ZIPs incl. 91230 (#26). Coordinates/areas refreshed from the Census 2024 Gazetteer, demographics from ACS 5-year vintage 2023. - zcta_crosswalk: rebuilt on the 2020 ZCTA/tract vintage (168,212 rows). - zip_to_cd: rebuilt on the 119th-Congress relationship file (#29), following the method of PR #30 by @awallender. Tests updated where they pinned exact 2-decimal legacy coordinates, and extended with schema-contract and regression-ZIP checks.
