Remark. Prompt breadth is not a total order [ftip-00AN]

The records in Definition [ftip-00AM] change several coordinates together. The prompt-pool size, domain mixture, and repetition frequency differ. Across the paper's Qwen and OLMo studies, the starting artifact and evaluated tasks also differ.

We therefore use ``narrow'' and ``broad'' as names for the source cells. They do not define a total order on prompt laws, and their comparison does not identify a causal effect of breadth alone. A breadth theorem would need a declared statistic and matched configurations that differ only in that statistic.
