    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

    When declaring one interpretive view, proceed in this order:

    1. Entry test. Confirm that one already-declared substrate exists and that the current inspection question can cite it either directly or through one declared source-set entry point or set-result entry point that keeps it recoverable, rather than drifting into substrate repair, publication, or policy.
    2. Name the active interpretive head. Use ordinary DeclaredSubstrateInterpretiveView unless the current reading genuinely needs the fuller atlas form.
    3. Cite the base line. Name the already-declared substrate the view is reading, or cite the source-set entry point or set-result entry point together with the recoverable substrate it depends on.
    4. State the inspection question directly. Say what the view helps the reader see that the substrate alone leaves hard to inspect.
    5. Keep the base source/result recoverable. Name the active source set, and if the view is over one declared front, archive, shortlist, palette, or other set result drawn from that source, keep that active set result recoverable too.
    6. Recover derived-view and palette structure when it matters. If the view depends on one derived tradition or palette reading, state DerivedViewKind and BasePaletteRef.
    7. Add the actual qualifiers. Add TypedSetViews, cited spaces, declared map refs, metrics, transition qualifiers, or distortion notes only when the current reading truly depends on them.
    8. Run the preservation check. If the interpretive prose would materially change the base source-to-outcome relation or the base distortion/uncertainty/error posture, stop and reopen the substrate declaration.
    9. Run the boundary check. If the prose starts changing the EntityOfConcern, minting new generic view law, publishing selected sets, shipping outputs, or deciding policy, apply the pattern that governs that question.

    Fail-closed rule. Do not treat the line as a interpretive view if steps 2-7 cannot be completed honestly. Missing base-line recovery or hidden posture change is a real defect here.
