I went to the college board website and this is what I found:
You are also required to:
investigate your computing innovation using a variety of sources (e.g. print, online, expert interviews);
cite at least three sources that helped you create your computational artifact and/or formulate your written responses;
At least two of the sources must be available online or in print; your third source may be either online, in print, or a personal interview with an expert on the computing innovation.
At least two of the sources must have been created after the end of the previous academic year.
produce a computational artifact that illustrates, represents or explains the computing innovation’s intended purpose, its function, or its effect; and
provide written responses to questions about your computational artifact and computing innovation.
A possible scenario is that they find an expert and have them review the innovation. What do you think?
