The step declares its scope up front: human mapping only, with each
Hermes profile bringing its own AI peer. A note explains aliases as
the join between platform accounts and named peers. Each shape now
says when it fits. Fresh configs default the choice to [1] single
peer — the common personal setup — instead of [3], which silently
fragmented a solo operator's gateway account away from their
peerName history. Configured setups keep their detected shape as
the default.
