Read the compatibility matrix
Synthetic data revision D4 requires config C2. Available configs C1 and C3 are explicitly not compatible with D4 in the supplied matrix. No adaptation is approved. Configs contain references only; no credentials appear in the worksheet.
| Data/config pair | Compatible | Config available |
|---|---|---|
| D4/C1 | No | Yes |
| D4/C2 | Yes | No |
| D4/C3 | No | Yes |

A higher config number cannot override an explicit incompatibility entry.
How many available compatible configurations exist?
Show the worked answer
Zero. C2 alone is compatible but absent; C3 being newer does not make D4/C3 eligible.
Record the missing configuration
| Case | Decision | Reason |
|---|---|---|
| Use C3 because newer | Reject | Matrix says incompatible |
| Locate C2 | Eligible material candidate | Matches D4 |
Retain the required config revision with the backup manifest, then test the restored task. This drill does not infer compatibility for unlisted versions.
