Given an FDA-assigned recall_number, returns recall metadata plus Medicare Part D and Medicaid SDUD federal spend on the recalled drug during the recall window (initiation -> termination), summed SERVER-SIDE with per-year Part D rows and per-NDC Medicaid rows riding the answer. The recall source carries NO NDC (openfda_product_ndc_first is NULL on all 17,830 current rows), so the Medicaid leg reaches NDCs through dim_drug on the openFDA product name and says so. Each leg reports its own published-year coverage, so 'no spend', 'not published yet' and 'no join key' are three different answers instead of one null.

Medicaid totals EXCLUDE the SDUD national roll-up, which CMS publishes under state 'XX' beside the 50 state rows and which would otherwise roughly double every Medicaid figure.

Reference demo: recall_number D-1489-2019 (Fresenius Kabi fluorouracil, Class I, window 2019-2022) exercises both legs and the NDC bridge. This description quotes NO dollar figure on purpose: the answer is the only place a number lives, so a change to the computation can never leave a stale figure in the documentation. It did once -- the demo totals here were the pre-2026-08-10 national-roll-up double count and stood six weeks after the fix.
