# CMS QHP Enrollee Survey PUF: current read surface (one CMS artifact per plan year)

`medicare_semantic.vw_enrollee_survey_puf_current_v1` · Insurer negotiated rates · status live · 1,586 rows

The read surface over medicare_silver.fact_enrollee_survey_puf_history (append-only): for each business_year it keeps one CMS data unit (cms_vintage_sequence DESC, then asserted_at DESC, then archive member as tie-breakers) and returns its publisher rows unchanged (raw_values_json keyed by ordered_header_json). Defined in pipelines/medicare/semantic/enrollee_survey_puf_current_v1.sql (#3583). A later CMS repost of a plan year replaces the earlier artifact here and stays in the history table.

**Grain.** One publisher row of the selected data unit per business_year: 1,586 rows PY2022-2026, one CMS artifact per business_year (266 / 298 / 325 / 343 / 354; Athena bccf9835, 2026-10-13).
