Expected vs. Found
| ✓ | Expected: The scanned page's text should appear in the output instead of being skipped.Found: The scanned page is transcribed in place with the digital pages; it is present and not skipped. |
Why this result
It is a pass because the image-only page is present in the output like the others: the scanned worksheet is transcribed in place, the service reports all three pages processed with OCR on, and the only differences are a date glyph and missing footer spaces.
Also observed in this test case
Footer spacing changed. The scanned page's footer comes back without spaces, unlike the digital pages' footers.
OCR ran by default. The response reports OCR on, so the default Document Parse flow recognized the scanned page without a special endpoint or flag.

How this scenario is graded
How we decide Pass, Fail and Not gradable. The same rules apply to every tool tested on this scenario.
How results are decided
Each test case gets one result per tool: Pass, Fail or Not gradable. A test case we haven't run yet shows Untested. There are no partial results.
The rules
- Pass: the tool did everything the test expected, and nothing it said contradicts the correct answer.
- Fail: at least one expected behaviour clearly didn't happen; the test case's result says which one and quotes the tool.
- Not gradable: our evidence couldn't settle the outcome (for example a record we needed is missing). It is never counted as a fail, and the test case's result says what's missing.

Act on this result
Nothing filed here edits the run or the grade. A challenge opens a review, and a review can produce a new run or a re-grade — which becomes the current result and leaves this one in the history.
This matches what I see
You run the same kind of test against your own setup and get the same behaviour.
Agree →This does not match
Yours behaves differently. Tell us what you got, with a screenshot if you have one.
Disagree →Point out an issue
Something here is wrong — a reference value, a transcription, a grade.
Report an issue →We have fixed this
Tell us what changed and we schedule a rerun of the failing test case. The old result stays as history.
Vendor notice →Filed against this evidenceNothing yet. Challenges, counter-evidence and fix notices appear here with their outcome, and stay on the page after they are resolved.
