CropMath Error Taxonomy Protocol

Annotate at least 200 incorrect core-model predictions sampled across model, condition, family, and mode.

Allowed primary/secondary error types:

• formula_selection_error
• parameter_substitution_error
• arithmetic_computation_error
• branch_condition_error
• sensitivity_change_handling_error
• unit_precision_rounding_error
• final_answer_extraction_format_error
• hallucinated_or_ignored_formula

Set parser_extraction_correct to yes, no, or unclear after comparing the raw response with the parsed prediction.
