Distinguish file time from content boundary
Synthetic export generated 10:10 includes complete sequence 1–120 through 10:00. Requested cutoff 10:05 includes sequence 1–135. Records 121–135 are not in the file. Sequence increments are one record each and there are no deletions in this drill.
| Property | Observed | Required |
|---|---|---|
| File generation | 10:10 | Not content cutoff |
| Content boundary | 10:00 /120 | 10:05 /135 |
| Missing range | 121–135 | 15 records |
Compare required and included ranges
- Read the content boundary metadata
- Subtract included identities from required
- Report the incomplete scope
A newer file timestamp cannot change its stated content cutoff.
How many requested records are covered and missing?
Show the worked answer
120 of 135 covered, about 88.89%;15 missing. Generation after 10:05 does not establish inclusion through 10:05.
Label a partial output accurately
| Case | Decision | Reason |
|---|---|---|
| Use generation 10:10 as completeness | Reject | Content ends 10:00 |
| Label partial 1–120 | Accurate scope | Missing 15 remain explicit |
Obtain an output with the required boundary or an explicit changed request. Preserve the original partial file identity for comparison.
