Concurrency Coordination Reports
Abort Flag Coordination Report
Stop processing a fixed batch once a scalar abort threshold is reached and report the final state.
abort flag
This report models cancellation as a scalar abort flag rather than a live signal object, so the stopping point traces deterministically.
