test-github-action.yml

name: Test github-action/ Composite Action

# Runs on every PR touching github-action/ (the cloud-API variant) and on
# the same paths landing on main. The Rafter API is NOT exercised — these
# are pure-bash unit tests of the threshold-eval and PR-comment logic
# plus a drift detector on action.yml's load-bearing defaults.
#
# An end-to-end test against the real Rafter API is a future addition
# (would require an injectable RAFTER_API_KEY secret and a fixture repo).
