# CMS Marketplace Quality PUF: current read surface (one CMS artifact per plan year)

`medicare_semantic.vw_quality_puf_current` · Insurer negotiated rates · status live · 35,752 rows

The read surface over medicare_silver.fact_quality_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/quality_puf_current.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: 35,752 rows PY2017-2026, one CMS artifact per business_year (830 / 553 / 768 / 3,511 / 3,885 / 5,407 / 6,378 / 5,395 / 4,723 / 4,302; Athena 7678a908, 2026-10-13).
