E.18.NET:4.4 - Keep valuation and design/run state leaf-local

Each positionBindingRef cites an E.18 position/valuation binding or a declaration-local binding whose pattern defines the needed participant meanings, value kind, and reference mode. A network introduces no universal cross-flow value kind.

DesignRunTag belongs to one exact position binding inside one exact leaf TFS. A network has no network-level FlowValuation, global design/run ladder, or automatic crossing that changes the carried entity’s kind. If the same episteme fills local positions in different members—for example one position concerned with design work and another with production, verification, or later operation—record each leaf-local binding and the exact relation that obtains between them. Those ordinary member descriptions create no fixed TFS taxonomy or lifecycle phase.
