Three script runs passed with the same baseline/failure/repair outcomes. The final run used exact endpoint-count and abnormal-exit checks; sample-output.txt records that run.
Each failing subscriber had a 15-second observation window. Exact timing, node IDs, and GIDs vary.
These results do not measure packet loss, network latency, or hardware performance.
