The Fixture and the low-level model backbone deserve a distinct namespace on their own. Since it's built by the Builder from the Session contents, and also used by the frame dispatch, we can expect dependence on some types from Steam-Layer, and thus this namespace needs to reside in Steam-Layer rather, while the actual low-level Model might become part of Vault-Layer, creating a hierarchy of data structures. (Remark: likely also the session related namespaces will need a reorganisation)
