Patterns by kind of event
Playbooks differ. In-person student events, online open-source events and agency data challenges reward different things, so read each kind on its own and mind the sample size.
Small samples, not causal. 35 confirmed winners and finalists in total; mechanism tags are mostly curator inference.
