Representation decoupling operates at two architectural scales through the same principle: within modules, input representations are separated from storage representations (dataclasses vs dicts, coordinator writes vs raw replicas); across the architecture, logical semantics are separated from physical state (offsets survive partition trimming, hash positions decouple from topology, delete markers decouple from data removal) — both enabling independent evolution of interfaces and implementations at their respective granularities.
Representation decoupling at module scale and architecture scale are the same principle at different granularities
