Generation time budget (minutes) Generation iterates until this deadline instead of a fixed number of rounds. Run the full pipeline After the challenge builds with placed flags and each flag is checked, automatically run a solvability check: an agent given the exploit guide must capture every flag against the live app. Calibrate difficulty Run a baseline tool against the finished challenge with no writeup to measure how much it can solve unaided, and gate on it. Adds a full baseline solve (roughly 15 to 20 minutes and extra cost).
