# m12p5 T4 overlay — SINGLE replication group (no `shards:`).
#
# T4 is REPLICA elasticity + idle-readiness (scale the voter set 3→5→3), NOT
# sharding (that is m12p4/T5). A single group RF=all is the faithful T4 shape:
# it mirrors the in-process exit gate `mp_scale_3_5_3_under_load_zero_loss` and
# uses the well-proven m11p5 seed-join path (the sharded-cluster *replica*
# scale-up — 5 replicas per group — is an untested path outside m12p5's scope).
#
# Strategic-merge replaces the base ConfigMap's `cluster-topology.yaml` value:
# identical to k8s/cluster/topology-configmap.yaml MINUS the `shards:` block, so
# every pod runs ONE group binding gRPC 9601 (the extra 9602/9603 containerPorts
# in the StatefulSet are simply unbound — harmless).
