# The repository uses the sha256 git object format. Git < 2.42 cannot speak
# the sha256 wire protocol, and actions/checkout@v4 does `git init` without
# --object-format=sha256, which produces `fatal: mismatched algorithms:
# client sha1; server sha256`. We therefore skip actions/checkout entirely
# and clone manually from a trixie-based container (git 2.47+).
