# CI Performance Analysis
#
# Analyses the most recent successful runs of the main build-and-test
# workflow (pull-request-checks.yaml) and publishes a Markdown summary
# of the slowest jobs, test suites, and individual tests.
#
# Results are visible in the GitHub Actions UI:
#   1. Go to the "Actions" tab of the repository.
#   2. Select the "CI Performance Analysis" workflow on the left.
#   3. Click the most recent run, then the "analyse" job.
#   4. Expand the "Summary" section at the top of the job page.
#
# The underlying script is scripts/ci_analysis.py.  Run it locally with
# --help for additional options (e.g. --runs, --top, --log-dir).
