Followup prompt:

Actually, I do have a question: If I provided an update, could you pull all the info you could, plus identify for each listing, where else I should look, based on the nature of the listing?

and the response (ignore the fact that Claude and I already have a relationship):

Yes – and it would layer naturally on top of your existing reformatting workflow rather than replace it.

For each listing you pass along, I’d do two separate things. First, pull whatever’s publicly findable on it – press releases, prior designation history, news coverage, anything that adds context beyond the bare SDN entry. Second, and this is the part you’re actually asking about, tell you specifically where to go dig further, chosen by what kind of listing it is rather than handing you the same generic list every time.

That second part is where the nature of the listing matters. A few examples pulled straight from the pattern in your own recent updates:

• A vessel or shipping entity tied to an Iran designation (HormuzSafe, the shadow fleet tankers) – I’d point you to Equasis for registered owner, manager, and flag history, plus Windward or Lloyd’s List Intelligence and UANI or C4ADS for the network picture.
• A crypto exchange entity like the Shelbit network – blockchain analytics platforms (Chainalysis, TRM Labs, Elliptic) and on-chain explorers matter more here than corporate registries, since the trail runs through wallets as much as paperwork.
• A Cuba military-industrial entity tied to GAESA or MINFAR (Tecnoimport, UIM) – ASCE and Cuba Study Group research tend to go deeper than general corporate databases, since a lot of that structure never shows up in any commercial registry.
• A Russia entity – OpenSanctions or OCCRP Aleph first, since they’ve already scraped a good deal of EGRUL, then the Ukrainian NSDC list and the KSE tracker for anything more recent than what’s been indexed.
• A plain corporate or individual addition with no obvious sector hook – OpenCorporates and the registry of wherever it’s domiciled, plus a check of whether OFAC’s own AKA or Linked To fields already answer the question.

One caveat, consistent with what I said earlier: the first half I can actually run myself. The second half means I’m handing you the right door, not opening it – I still can’t get past the paywalls on Orbis, Sayari, or Kontur/SPARK, so for anything that needs those, that’s where you’d take it from there.
