Given an NPI (10-digit), returns OIG LEIE exclusion status and — if excluded — any Open Payments received OR Part D prescribing activity recorded AFTER the exclusion date (and before any reinstatement). The textbook qui-tam / False Claims Act screening query. Bridges three substrate sources: dim_oig_leie (LEIE), fact_drug_payment_to_prescriber (Open Payments), fact_part_d_prescriber (Part D Prescriber-by-Drug).

Returns: total post-exclusion payment dollars + Part D drug-cost exposure, broken down by year + top 5 manufacturers. Every answer carries an explicit exclusion_status (not_in_leie, excluded, or excluded_then_reinstated) beside the dollars, so a $0 result is never ambiguous: a not-in-LEIE NPI returns zero ANCHORED to the LEIE snapshot date it was checked against (leie_asserted_at), which is a different thing from an excluded prescriber who drew no post-exclusion payments.

KNOWN GAPS: open_payments_publication_lag_one_year (current PY publishes June+1); part_d_puf_annual_grain_only (Part D PUF is annual not monthly — finer-grain timing requires claims data). LEIE refreshes monthly per the M-6 schedule (cycle 2).
