The CAD Agent tools write straight to the document store, while the 3D scene and the BOM only sync on the manual path. After cad_place_profile or cad_build_frame reports success, the viewport still shows the old scene, the PNG export captures that stale view, and the BOM is not refreshed. The agent's parts appear only after some unrelated manual action triggers a sync.
