-- **The 24 lithium-ion scenarios** are not covered by that sample. As a supplementary check:
-  - two LLM raters from different model families rated them under the same rubric;
-  - the checkable ground truths were recomputed from the processed NASA PCoE data;
-  - the scenario author reviewed the AI ratings.
