jared	e53aeb9643	docs: warn raw-parquet readers that survey_weight is not an aggregation weight ... The v5 schema passes the legacy IndFin Weight column through verbatim as survey_weight. Census documents it as informational-only, and its encoding is inconsistent across vintages (reciprocal scale most years, direct in 2003, placeholder 1 in 1967-2001 gap years, all-0 in 2007-2012, NA modern), so weighting amt by it produces silently wrong totals. No uscogdata function reads the column; this warning is for direct DuckDB/arrow consumers. Evidence: cog_pipeline/.superpowers/sdd/weight-semantics-findings.md.	2026-07-23 12:22:24 -04:00
