Marks everything after it as experimental: downstream failures stop the run gracefully instead of failing it. Use it when adding a probe branch to a flow that runs against live data and can’t be re-run by hand. Anything reached after this node may crash, error, abort, or dead-end without an End node — the run stops there and finishes as if it had completed, with the failure recorded in the run’s log and error list rather than turned into a red run.

Configuration

  • Label — optional name for the experiment, included in the log lines the shield writes.

Notes

  • The shield covers the rest of the run, not just the branch it sits on. Place it after everything that has to happen for real.
  • Failures that occurred before the shield engaged still count: the run ends Partial, not OK.
  • Cancelling the run still cancels it.
