  1. """Sanctions list collectors: UN consolidated, OFAC SDN, SECO (via OpenSanctions mirror), EU (probed/blocked).
  3. - UN: https://scsanctions.un.org/resources/xml/en/consolidated.xml (302 → follow)
  4. - OFAC: https://www.treasury.gov/ofac/downloads/sdn.csv (bonus, US Treasury SDN)
  5. - SECO: SECO publishes no stable anonymous bulk CSV/XML URL we could find
  6. (seco.admin.ch is JS-rendered; verified 2026-09-24). OpenSanctions
  7. mirrors the SECO list and republishes the *original* `source.xml`
  8. plus normalized exports daily; data CC BY-SA 4.0 (OpenSanctions) /
  9. public Swiss federal data. We store `source.xml` as-is with a
  10. provenance sidecar naming the mirror.
  11. - EU: https://webgate.ec.europa.eu/fsd/resources/trade-sanctions/consolidated-list/
  12. sanctions_conso.csv now redirects to EU Login even with
  13. `?anonymous=true` (verified 2026-09-24, with cookie jar) →
  14. recorded BLOCKED-needs-login; probe status file kept.
  16. All XML/CSV parsed at clean time; raw files streamed (UN consolidated.xml
  17. is tens of MB — stream to .part then rename).
