  const deleteHandlerLinkId = await deep.id(
    "@deep-foundation/logger",
    "DeleteHandler"
  );
  
  const myTypeLinkId = await deep.id(deep.linkId, "MyType");
  const containerLinkId = deep.linkId;
  
  const reservedLinkIds = await deep.reserve(1);
  
  const handleLinkId = reservedLinkIds.pop();
  
  await deep.serial({
    operations: [
      {
        type: "insert",
        table: "links",
        objects: {
          id: handleLinkId,
          type_id:
            handleInsertTypeLinkId /* handleUpdateTypeLinkId, handleDeleteTypeLinkId */,
          from_id: myTypeLinkId,
          to_id:
            insertHandlerLinkId /* updateHandlerLinkId, deleteHandlerLinkId */,
        },
      },
      {
