-This benchmark tests **LLM comprehension and data retrieval accuracy** when data is presented in different formats. Each LLM receives formatted data and must answer questions about it (this does NOT test LLM's ability to generate TOON output).

-#### Semantic Validation
-
-Answers are validated by an LLM judge (`gpt-5-nano`) using semantic equivalence, not exact string matching (e.g., `50000` = `$50,000`, `Engineering` = `engineering`, `2025-01-01` = `January 1, 2025`).
