## Data Source Labeling

When extracting numerical values, always indicate the source and reliability:

```markdown
## Replication Targets

### Figure 3: Training Loss

| Data Point | Value | Source | Reliability |
|------------|-------|--------|-------------|
| Initial loss | ~2.5 | Image extraction | REFERENCE ONLY |
| Final loss | ~0.12 | Image extraction | REFERENCE ONLY |
| Learning rate | 1e-4 | Paper text, Section 4.1 | HIGH |
| Batch size | 32 | Paper text, Section 4.1 | HIGH |
```

**Reliability Levels**:
- **HIGH**: Explicitly stated in paper text
- **MEDIUM**: Inferred from context or appendix
- **REFERENCE ONLY**: Extracted from figures - use for comparison, not as test targets

## Important: Reference Values Are Not Ground Truth

Values extracted from `image_understanding.md` (especially from plots) are approximate and should:
- Be used for **comparison** in the final report
- **NOT** be hardcoded as expected test outputs
- **NOT** cause test failures if code produces different values

The replicated code's output is authoritative. If our training produces loss=0.15 instead of the paper's ~0.12, this is documented and explained, not treated as a bug.

## Analysis Methodology

When analyzing a paper:

1. **First pass**: Extract basic info (title, authors, abstract)
2. **Method pass**: Understand architecture and algorithms
3. **Experiment pass**: Identify what needs to be reproduced
4. **Integration pass**: Combine with image_understanding.md
5. **Planning pass**: Create actionable replication plan
6. **Labeling pass**: Mark data sources and reliability levels

## Quality Checklist

Before completing:
- [ ] All sections of paper_structure.md filled
- [ ] Image descriptions integrated from image_understanding.md
- [ ] **Data sources labeled with reliability levels**
- [ ] Replication plan has clear module boundaries
- [ ] Each module has testable acceptance criteria (shape, gradient, sanity - NOT exact values)
- [ ] Dependencies between modules identified
- [ ] **Reference values marked as comparison targets, not test assertions**
