int_ks4_with_lineage.sql unions stg_ees_ks4 and stg_legacy_ks4 via `select *`, which PostgreSQL aligns positionally. stg_legacy_ks4 listed sen_support_pct before sen_ehcp_pct while stg_ees_ks4 lists sen_ehcp_pct before sen_support_pct, swapping the two values for legacy-sourced rows in marts.fact_ks4_performance. Reordered stg_legacy_ks4's final select to match. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_0146VHeLAWjDVE2B5uU67jCB
