SIE.10:9 - Consequences
Defects are localized to source, semantic, identity, composition, mapping, realization, interface, quality, or receiving-use layers. A bounded useful result can proceed without hiding excluded branches, and later changes can trigger focused replay through explicit dependencies.
The cost is several kinds of evidence and collaboration with domain and receiving practitioners. Some integrations that appear technically complete remain unresolved or stop because their identity, authority, or representative-use premises are missing.
