'on':
  schedule:
    # Daily at 03:17 UTC. These lanes are useful portability signals, but they
    # mostly duplicate adjacent PR lanes. Running them daily keeps visibility
    # for distro drift and less common portability failures without making every
    # pull request wait for the full duplicate runtime matrix.
    #
    # Daily lanes intentionally run the full configured test set for their
    # distro. They must not use PR relevance pruning: any code may have changed
    # since the last scheduled run, and failures must create or update the
    # tracking issue below so they do not go unnoticed.
