+# JetStream Go Suite Map
+
+This map tracks the Go suite families included by `scripts/run-go-jetstream-parity.sh`.
+
+- `TestJetStream`: core stream/consumer API and data-path behavior.
+- `TestJetStreamCluster`: clustered JetStream semantics, placement, and failover.
+- `TestLongCluster`: long-running clustered behaviors and stabilization scenarios.
+- `TestRaft`: RAFT election, replication, and snapshot behavior used by JetStream.
+
+Runner command:
+
+```bash
+go test -v -run 'TestJetStream|TestJetStreamCluster|TestLongCluster|TestRaft' ./server -count=1 -timeout=180m
