- The 36-hour qualifier is followed by a required writeup-and-evidence submission before ten finalists are confirmed.
Field notes
The schedule makes the qualification process unusually explicit: teams have a 36-hour online window, then must upload writeups and evidence before organizers validate results. The page says finalist selection includes an audit of solutions, evidence, and logs, and describes a mandatory online technical meeting with account distribution and a platform-access test.
