| SSI | the index: provision × exposure, 0–100 |
| P / W | provision score / exposure weight by road class |
| sigma_p / sigma_o | raw points earned / observable |
| C | coverage seen; below 0.60 the audit is withheld |
| parameters | per-check level, points, confidence, note, cited frames, verify verdict |
| status | verified · withheld · not_ratable |
