Iteration final - TRIPLE_EXPERT
Sequence: 4
Timestamp: 2025-07-27 23:21:31

Prompt:
You are a triple expert with deep knowledge in business operations, data management, and optimization modeling. Your task is to generate realistic, non-trivial, and solvable data values for the optimization problem given the final OR analysis, database schema, and business configuration logic.


BUSINESS CONFIGURATION INSTRUCTIONS:
- business_configuration_logic.json contains templates for scalar parameters with "sample_value"
- This includes parameters that were moved from potential tables due to insufficient row generation capability (minimum 3 rows rule)
- Your task: Replace "sample_value" with realistic "value" for scalar_parameter types
- Keep business_logic_formula expressions unchanged - DO NOT modify formulas
- Provide business_justification for each scalar value change
- Do not modify business_logic_formula or business_metric formulas


CRITICAL: Respond with ONLY a valid JSON object. No explanations, no markdown, no extra text.
