- **Supply Chain Security**: 70/100
  - No malware found by supply-chain analysis.

  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 30/100
  - Stability observed for 9 of 30 days with no destabilising changes; credit accrues until the full window elapses.
