    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

    If you are about to write one line that says what is being searched, what is being judged, and whether those two relations sit in one declared space or in two declared spaces, stop and fill this pattern before you write any more umbrella prose such as space, projection, portfolio, or front.

    Do this in the first minute:

    1. Name the active source set.
    2. Point SearchSpaceRef and OutcomeSpaceRef to declared CharacteristicSpace.
    3. Choose sameDeclaredSpaceAs or distinctDeclaredSpaceFrom.
    4. State the source-to-outcome relation in direction, mode, and carrier.
    5. State the governing posture token.

    If one of those five cells cannot yet be filled honestly, do not improvise around it. Either you are still in A.19, or you have really moved into interpretive-view work, publication, or policy, or the current line is still missing one declared basis.

    If the question under repair sounds like...Use nowWhy
    "Which space are we searching in and which space are we judging in?"A.19.SOURCE-SET-SPACE-SUBSTRATEThis pattern governs the dual-ref substrate stack.
    "How should I help the reader inspect that already-declared line?"A.19.DECLARED-SUBSTRATE-INTERPRETIVE-VIEWThat is one interpretive reading over the substrate, not the substrate declaration itself.
    "What do we publish, ship, keep live, or plan next?"G.5, G.10, C.19, or C.24Those are downstream output or policy questions.
    "I only need one space declaration."A.19No source-to-outcome substrate stack is in play yet.

    Common confusion to kill early: DescriptorMapRef, distance definitions, and OutcomeMapRef values may discipline the line, but they do not answer the first-minute substrate question unless the five cells above are already filled.
