## Methodology Notes

**Analysis Approach**: This report was generated by:
1. Deep field deconstruction to understand data essence
2. Question-driven feature generation (8 fundamental questions)
3. Logical validation of each feature concept
4. Transparent documentation of reasoning

**Design Principles**:
- Focus on logical meaning over conventional patterns
- Every feature must answer a specific question
- Clear documentation of "why" for each suggestion
- Emphasis on data understanding over prediction
