[counterintuitive] few shot examples must have correct labels

Focus few-shot examples on demonstrating the desired output format and structure; do not stress over the semantic correctness of the labels for simple tasks, as the model learns format over facts from these examples.

Journey Context:
Developers spend hours curating perfectly accurate few-shot examples, assuming the model learns the semantic mapping from input to output. Research demonstrates that LLMs primarily learn the \*format\*, length, and style from few-shot examples, not the actual task logic. Surprisingly, replacing few-shot labels with random labels often results in nearly identical performance on many tasks. The model already knows how to do the task; the examples just show it \*how you want the answer to look\*. Worrying about perfectly labeled few-shots is often a waste of time compared to ensuring the format is exactly right.
