 # Internode transport baseline runner.
 # Reuses scripts/run_object_batch_bench.sh and exports reproducible artifacts:
+# - run manifest with scenario/tool metadata and git revision
 # - object benchmark summaries per scenario/workload/concurrency
 # - optional internode operation metric deltas from a Prometheus text endpoint

 Notes:
   - This baseline covers S3 PUT/GET workloads and records internode metric deltas when --metrics-url is set.
+  - The run manifest intentionally omits access keys, secret keys, and extra args to avoid writing credentials to artifacts.
   - Healing/replication-specific workloads should be run separately and appended to the same artifact directory.
