GRADE B/D -- Graph analysis, flight records, jmail corpus limitations
Top co-appearing individuals: John Brockman, Alan Dershowitz, Ghislaine Maxwell, Virginia Roberts. Top travel companions: Heather Mann, Ghislaine Maxwell, Ira Zicherman, Ralph Ellison, Henry Rosovsky, Prince Andrew, Bill Clinton, Sarah Kellen.
The query for post-death network activity returned zero results. Neither Nikolic nor Maxwell has post-death document connections in the corpus. This likely reflects the corpus ending rather than genuine network collapse -- the jmail ends September 2018, and the DOJ corpus has minimal 2019 content.
The final jmail emails date to September 9, 2018. Last contacts include Daniel Schmachtenberger, Lesley Groff (scheduling), Steve Bannon ("Not really good enough"), and Aeroflot bookings to Paris. Five "goodbye" emails exist in the corpus but none from the critical period. Karyna Shuliak's last significant message: "I felt so terrible...when I realized you left and I did not say goodbye" (November 2, 2018).
