# One job, because the flake is the build.

# This used to be a kaniko pipeline whose only purpose was to publish the
# container image buck2's remote executor pulled; nothing about it ran the
# build. `nix flake check` runs fmt, clippy, the test suite and all three
# shared objects, and it pins what it runs with.
