A part without a known datasheet comes back 'queued' while we look for its PDF; check_extraction_status shows it as 'resolving' until the search ends. Only then is 'no_source' final: check the part number, or use request_datasheet_upload + confirm_datasheet_upload to attach your own PDF (org-private).

Do NOT pass bare values ('100nF', '10K'), descriptions, BOM reference designators, test points, or board/module names — see the server instructions for the full rule set. When a BOM has values-only rows, use search_parts first to resolve each to an MPN.
