Practice shelf / fictional task
Catalog cards
A fictional practice exercise: a little library keeps handwritten titles in order. Two people disagree about which card should come first.
Describe the rule
Before comparing implementations, write down what “in order” means. Include a few cases that distinguish plausible interpretations.
Record the disagreement
Keep the original inputs and both proposed outputs. Describe the earliest point where the two rules diverge.
This is an original fictional example, unrelated to a live evaluation.
