What a Sprint is.
One sealed challenge, a fixed window to build something, and then you answer for it out loud while another team tries to break it.
A chapter can run for a whole year without entering one. Sprints exist for students who want to find out how their work holds up in front of people who did not build it.
NO SPRINT HAS A CONFIRMED DATE. ONE GETS SCHEDULED WHEN THERE ARE JUDGES, NAMED SUPERVISING ADULTS, AND ENOUGH CHAPTERS TO FILL A ROOM. IT WILL BE ANNOUNCED HERE WITH A DATE, NOT BEFORE.
Sealed until the start, then published to everyone at the same moment. A real deliverable, not a puzzle.
Build it. Any tool is allowed, and every use of one goes in your build log.
You receive another team's work. You file what held and what broke, and you sign it.
Live questions from judges and from the team that audited you. "I don't know, but here is how we checked that part" is a good answer.
Another team tries to break your work in front of you, within bounds published alongside the challenge. You respond in real time.
Artifact, audit accuracy, defense, explanation, honesty. A claim that collapses under questioning costs more than an uncertainty admitted up front.

What it takes to enter.
| What it costs | Nothing. Open Sprints carry no entry fee. |
| What you need | Nothing. No chapter, no school, no advisor, no special software. |
| Who competes | You alone, or a small team. Either way the work is scored per person rather than per team, so nobody hides inside a group. |
| How many | Capped by how many defenses fit in one room in one day. The cap gets published with the date. |
Worst case, you find out what a red-team round feels like before it ever counts for anything.
Hear when one is scheduled.
One email when a Sprint has a date, judges, and adults confirmed. Nothing until then.
AN EMAIL ADDRESS IS ALL THIS COLLECTS. IT IS NEVER SOLD, AND VENDORS NEVER SEE IT.
Judging one instead.
A Sprint needs people willing to ask the next question: teachers, engineers, researchers, anyone who has had to defend their own work to someone who was not already impressed by it. Judging takes an afternoon and no preparation beyond reading the challenge.
If that sounds like you, use the form above and say you want to judge. The judges for any Sprint get published with the date, by name.
