# The release workflow gates a tag, which is late: a broken commit sits green
# until somebody decides to publish. This runs the same checks on the way in.

# push is scoped to main so that a branch pushed as part of a pull request is
# not checked twice.

# A rapid series of pushes only needs the last one checked.
