jared	515ab3b019	docs: survey_weight is col 28 under schema v6 (was col 26 in v5) ... Rebase onto the v6 main (bd53230) shifted survey_weight from col 26 to col 28: v5→v6 inserted cog_legacy_state/cog_legacy_county at positions 10-11 (26→28 cols). Position confirmed against the regenerated v6 fixture and both corpus docs (reader-specification.md §3 'Long parquet schema (28 columns)' row 28; data_dictionary.md '28-column schema v6' row 28).	2026-07-23 12:22:25 -04:00
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

Internal session layer with lazy cog_open(), manifest fetch+validate+cache, view registration placeholder. Depends on DuckDB >=1.0, httr2, jsonlite. inst/schemas/provenance-v1.json ships the structured provenance JSON Schema.	2026-04-23 09:05:54 -04:00
