# The vectors are generated in autonomous-code by apps/esp32-circle/scripts/gen_cable_vectors.py — a
# third implementation written from the format description, so neither the firmware's decoder nor this
# repository's blesses its own misreading. That only holds while the copy here is current: a stale copy
# lets both suites pass while the real cable disagrees.
#
# The source repository is private and most people cloning this one will not have it. Its absence is
# therefore NOT an error — the copy is checked in and works on its own; this script exists for whoever
# changes the format.
