Record what was actually tested
Synthetic review runs config C8 on day 10. Reusable evidence must be≤7 days old and tested C8 exactly. E1 tested C7 on day 9, E2 C8 on day 2, E3 C8 on day 6. All were successful for their tested scope, but no equivalence between C7/C8 is supplied.
| Evidence | Config /age days | Eligible |
|---|---|---|
| E1 | C7 /1 | No: mismatch |
| E2 | C8 /8 | No: stale |
| E3 | C8 /4 | Yes |
Check age and identity independently
- Read tested configuration identity
- Calculate age from review day
- Require both conditions
A successful old-version test cannot be relabelled as the current version.
How many reusable evidence records qualify?
Show the worked answer
One, E3. E1 fails identity despite being recent; E2 fails age despite matching C8.
Choose only matching evidence
| Case | Decision | Reason |
|---|---|---|
| Use newest E1 | Reject | Tests C7, notC8 |
| Use E3 | Eligible scope evidence | C8 and 4≤7 days |
Carry the tested task scope with E3. Matching configuration and age does not extend its result to tasks the rehearsal never executed.
