+# Isolated test-relay backing stack — GUI read-model overhaul harness (Dawn).
+#
+# A SEPARATE Compose project (`buzz-harness`) so the shared :3000 relay and the
+# default `buzz-*` dev stack are never touched. No fixed container_names (they
+# collide across projects) and alternate host ports. Mirrors Eva's evaperf-*
+# isolation pattern.
+#
+#   Bring up:  docker compose -p buzz-harness -f docker-compose.harness.yml up -d
+#   Ports:     postgres 5471 · redis 6471 · minio 9471/9472
+#   Relay (run separately by scripts/start-isolated-test-relay.sh):
+#              main 3030 · health 8088 · metrics 9202
