## 🏷️ Fine-Grained Component Taxonomy (`taxonomy.yaml`)
| Class ID | Class Name | Description |
| :--- | :--- | :--- |
| `0` | `cpu_socket` | LGA, PGA, or ZIF processor socket footprints |
| `1` | `gold_finger` | Gold-plated edge connector contacts (PCIe, RAM contacts) |
| `2` | `ic_chip` | Packaged ICs and BGA microchips |
| `3` | `tantalum_capacitor` | SMD tantalum capacitors (molded yellow/black/orange) |
| `4` | `forcibly_desoldered_pad` | Exposed pads with jagged solder, blowtorch marks, torn traces, burnt flux (**fraud signal**) |
| `5` | `factory_unpopulated_pad` | Clean silkscreen outline with smooth solder dots left empty from factory (**NOT fraud**) |
| `6` | `occluded_region` | Footprints obscured by heatsinks, metal shielding, or heavy dust |

## ⚡ Next Steps & Usage Guide
1. **Upload to Google Drive**: Upload this entire `google_drive_export` folder (or `ewaste_purity_index_drive_package.zip`) to your Google Drive.
2. **Annotation Review**: Import `dataset_annotated/data.yaml` and `dataset_annotated/labels/` alongside your images into **CVAT**, **Label Studio**, or **Roboflow** for annotation review.
3. **YOLO Model Fine-Tuning**: Pass `dataset_annotated/data.yaml` to `ultralytics` to train your baseline YOLOv8 model:
```python
from ultralytics import YOLO
model = YOLO("yolov8n.pt")
model.train(data="dataset_annotated/data.yaml", epochs=50, imgsz=960)
```
