    What this page is

    This is generated FPF reference text from the specification preface or supporting sections. It helps interpret FPF; it is not FPF Reference product documentation.

    Methodology

    Use it to understand how the specification wants to be read, then return to a route, pattern, or work packet for active work. Cite generated IDs only when the wording changes the task decision.

    Content

    • Situation and question. A description, view, dashboard, explanation, model, report, or publication is to be created, compared, transformed, or relied on. Ask which unresolved EntityOfConcern, viewpoint, representation change, lost structure, source set, or architecture use blocks the current use.
    • Template A. E.17.0 Solution -> DescriptionContext. Select for the generic describing case: name EntityOfConcernRef, BoundedContextRef, ViewpointRef, resulting view or view family, and any correspondence relation needed for the current comparison.
    • Template B. A.6.3.RT Solution -> RepresentationSchemeTransitionRelation@Context. Select when the same EntityOfConcern is being re-represented and a named receiving use relies on recovering the source representation, receiving representation, preserved claim or commitment, source-relation chain, representation-scheme delta, loss or recoverability, admissible use, and non-admissible downstream use. The relation records the concrete case; RepresentationSchemeTransition remains the method-pattern name.
    • Template C. C.33 Solution -> StructuralInformationAdequacyNote@Context. Select when the current question concerns what structure a description or view captured, lost, hid, and which wider source structure receives return for the declared architecture use.
    • Template D. E.17.ID.CR Solution -> ComparativeReviewUnit. Select only for bounded comparison over already available source epistemes or publications. It is not the generic description result.
    • Template E. C.30.AD Solution -> ArchitectureDescriptionUseCard@Project. Select when the subject is specifically an architecture description or view and its admissible architecture-use boundary is current.
    • Boundaries. Stop at the smallest result answering the current description-use question. Return when EntityOfConcern, context, viewpoint, representation scheme, captured structure, source edition, comparison basis, or intended use changes. A publication carrier does not become its subject, and a readable view does not become evidence, assurance, permission, decision, architecture, or work without the corresponding governed relation.
    • Public coarsening. "Description use" restores to DescriptionContext, RepresentationSchemeTransitionRelation@Context, StructuralInformationAdequacyNote@Context, ComparativeReviewUnit, or ArchitectureDescriptionUseCard@Project under the stated condition.
