The port tables were wrong in both directions: inter-node traffic is QUIC over
UDP rather than TCP, and the shard range 9991-9993 no longer exists. Ports are
unique within a host rather than across the cluster, so every machine uses the
same three, and a single-node install opens only the S3 port because colocated
nodes talk over an in-process pipe.
The reference architectures scripted a move of node data out of a directory
layout that no longer exists, which would have broken any install following
them. The update guide now says object storage has no migration path.
