ExecutionDoes it actually run? How much of the promise is real?	20%
UsefulnessWould a real person use this? Is the problem worth solving?	15%
Technical QualitySound architecture and sensible tradeoffs for a 30-minute build.	12%
Design & UXClarity, polish, and accessibility of the interface.	12%
Effective Use of AIIs AI load-bearing here, or decorative?	13%
Completion in TimeHow much shipped inside the clock, per the disclosure fields.	8%
Demo & PresentationDid the live demo land? Was the process explained well?	5%
