Server-provided instructions

Untrusted server output shown for inspection. It is not Koskamo guidance and is excluded from knowledge search.

Plumbline screens a person or company name against the US Treasury OFAC SDN list and its aliases in seconds, returning each match with its score, entry number and programs and the list's publication date; a match is a lead for review, not a determination. Its company checks (LEI and SEC registration, SEC-reported XBRL figures and federal contract awards) answer from the public registries where they are running, and every answer names the record it came from. Use list_propositions to see Plumbline's services, describe_proposition for one of them, then submit_request or an operation tool.
