# RC Smoke — post-publish validation against the npm RC artifact
# =============================================================================
#
# Stage: RC-SMOKE in the RC pipeline.
#
# Fires automatically after release.yml ("Release" RC path) completes
# with conclusion: success. Synthesizes example_rc_smoke/ from the demo app
# with react-native-appsflyer pinned to the RC version from npm, runs
# SMOKE-001/002/003 via af-scenario-runner.sh on both platforms, and posts a
# check_run named rc-smoke/npm on the release branch head SHA. That check_run
# is what promote-release.yml verifies before stripping -rcN.
#
# Manual dispatch is supported for reruns (rc_version input).
#
# When the parent RC-release run was dry_run=true, this workflow still fires
# but short-circuits and posts a skipped check-run so promotion can
# distinguish "not applicable" from "failing".
