| Drupal application only | Users who only need to know whether it is Drupal | Drupal traces, module or path fingerprints, DNS or CNAME patterns, and deployment behavior | It cannot directly answer the hosting platform or brand | Low | Best as the application layer |
| Drupal hosting model | Users who need to judge self-hosted, managed-platform, and shared or cloud environments | Separate self-hosted Drupal, managed Drupal platforms, and shared or cloud-hosted environments | It needs more context and cannot be settled from application traces alone | Low-medium | Best as the main decision layer |
| Brand and provider final pass | Users who need the final platform and responsibility boundary | The Drupal stack does not automatically equal Pantheon, Acquia, or any one raw provider | Public evidence may not always reach 100% certainty | Medium | Best as the final judgment layer |
