E.18:15c - E.18.3 Constraint-Governed Unfolding Relation

Open E.18.3 when one A.22-selected CGUS is being qualified by its use of an independently identified E.18 substrate. Name selectedCGUSRef separately from the mutually exclusive one-TFS, parent-relative internal-SubflowRef, or E.18.NET substrate branch; then recover the transformed concern, exact substrate positions and bindings, already-obtaining transfer or dependency occurrences, paths or slices, crossings, applied-condition claims, any E.18 GuardFail events with their gate-assignment facts, any independently defined guard-relation occurrences, optional valuation, preserved and lost transformation structure, non-admissible overreads, and the ordinary stop or reconsideration question.

This relation is deliberately narrow. E.18.3 can organize a transformation-flow slice inside P2W, P2S, work-control, architecture-feedback, evidence, narrative-publication, or refresh situations, but every stronger neighboring claim needs its independently identified value, exact supporting relation, applicable predicate-definition content, and current facts. A path card, graph expression, route prose, workflow diagram, or demonstrative slice remains a description or teaching slice until both the A.22-selected CGUS and its independent E.18 substrate use are recoverable; the pattern reference adds no connection relation.
