# Shared freshness gate used by the Docs Deployment workflow
# (superset-docs-deploy.yml) both up front (check-freshness) and again right
# before the deploy step (recheck-freshness). Writes an output declaring
# whether BUILD_SHA is still master's current tip, so a superseded run can
# skip cleanly instead of racing (and clobbering, or being force-cancelled
# by) a fresher run.
#
# Required env vars:
# BUILD_SHA - the commit SHA this run is building
# REPO - "owner/repo" to query, e.g. github.repository
# OUTPUT_NAME - the GITHUB_OUTPUT key to write, e.g. "is-current"
# GITHUB_OUTPUT - path to append outputs to (set by the Actions runner)
# Optional env vars:
# EVENT_NAME - if "workflow_dispatch", bypasses the check and always
# reports current, since a manual dispatch is a deliberate,
# one-off action rather than something racing other triggers
# GH_TOKEN - passed through to `gh`, needed to call the GitHub API
