## 🎯 The Four TRACE Metrics (Quick Recap)

| Metric | Measures | Formula | Range |
|--------|----------|---------|-------|
| **R (Relevance)** | % of docs relevant to query | `\|relevant\| / 20` | [0,1] |
| **T (Utilization)** | % of relevant docs used | `\|used\| / \|relevant\|` | [0,1] |
| **C (Completeness)** | % of relevant info covered | `\|R∩T\| / \|R\|` | [0,1] |
| **A (Adherence)** | No hallucinations (boolean) | All fully_supported? | {0,1} |

---

## 📊 Data Sources for Metrics

All metrics are calculated from the GPT Labeling Response JSON:

```
all_relevant_sentence_keys      → Used for R, T, C metrics
all_utilized_sentence_keys      → Used for T, C metrics
sentence_support_information[]  → Used for A metric (fully_supported flags)
overall_supported              → Metadata
```
