name: CI

# 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 rather than all branches so that a branch pushed as part of a
# pull request is not checked twice.
#
# No actions/checkout, deliberately -- same as the letsvisit and charts workflows. The
# runner image is ubuntu:22.04 whose `nodejs` package is Node 12, and actions/checkout@v4
# is built with ES2022 static initialiser blocks, so it dies with
# `SyntaxError: Unexpected token '{'` before running. Cloning with git directly avoids JS
# actions entirely. This repo is public, so the clone needs no credential at all.
#
# `${{ }}` values are passed through `env:` and referenced as quoted shell variables: a
# ref name is attacker-influenced by anyone who can push a branch or open a PR, and
# expanding one straight into `run:` is a shell-injection vector.
