    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

    Use one of these ordinary profiles:

    • Shared-space profile. SearchSpaceRef and OutcomeSpaceRef both resolve to the same declared CharacteristicSpace, and SpaceRefRelationKind = sameDeclaredSpaceAs.
    • Cross-space profile. SearchSpaceRef and OutcomeSpaceRef resolve to two distinct declared CharacteristicSpace declarations, and SpaceRefRelationKind = distinctDeclaredSpaceFrom.
    • Derived-source supplement. If the visible source set is one derived tradition, front, or palette view, keep DerivedViewKind and BasePaletteRef explicit so the derived view does not silently become the default meaning of the base palette or source set.
