# ScentEngine — Universal Training Annotations

Two-stage Gemma 4 labels (E4B primary, 31B verifier for conf ∈ [0.4, 0.7])
over public game screenshots. Each row maps an image to 6 PWM values
(0–100) in locked channel order: **Flora · Aqua · Earth · Pyric · Ozone · Civic**.

## Files

| File | Purpose |
|---|---|
| `public_games_final.jsonl` | All accepted labels (quarantine excluded) |
| `universal_train.jsonl` | 90% split for training the universal head |
| `universal_val.jsonl` | 10% split for validation / MAE eval |
