# The third-party oracles' Python packages.
#
# These are what stop the QR writer and the PDF writer being checked only
# against themselves. zxing-cpp decodes the symbols we drew; python-qrcode
# draws the same payload independently so the two matrices can be compared
# module by module — which is how the reversed format-information bits were
# found, a fault a decode-only check would have reported as "does not scan"
# and left us guessing. PyMuPDF and pypdf read the two documents back.
#
# Pinned, because an oracle that drifts is an oracle that stops meaning what
# it said last week. Install with `make oracles`.
