Your loop design
Describe your goal, repeated action, evidence, and exit. The rubric checks ten signals; “missing” means it wasn’t stated clearly.

What a solid loop states
A loop that scores 8+ answers four questions: what is it trying to accomplish, how will it know the latest attempt worked, what does it do with what it learned, and when does it finish or ask for help. Stop conditions are enumerated, not implied: success with evidence, no measurable progress, budget exhausted, blocker, or an approval boundary.
