#### Methodology
- **Semantic validation**: LLM-as-judge validates responses semantically (not exact string matching).
- **Token counting**: Using `gpt-tokenizer` with `o200k_base` encoding.
- **Question types**: ~160 questions across field retrieval, aggregation, and filtering tasks.
- **Datasets**: Faker.js-generated datasets (seeded) + GitHub repositories.
