    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

    OutcomeMapRef, SpaceMetricRef, TransitionRelationRef, and BridgeDistortionNote are admitted here only as interpretive qualifiers.

    They are declared first on the substrate side. This pattern may foreground or organize them for the reader, but it may not silently widen, narrow, or otherwise change the base substrate posture.

    Use them when the current interpretive view genuinely needs them:

    • OutcomeMapRef when the current reading must show how one declared source or set result bears on one outcome-side declared space/ref;
    • SpaceMetricRef when neighborhood, spread, reachability, or crowding claims are load-bearing in the current reading;
    • TransitionRelationRef when the current reading depends on explicit transition or cross-scale state-change qualifier;
    • BridgeDistortionNote when the reader must keep one declared loss or distortion visible near the current reading.

    If the interpretive view would newly introduce lossy-bridge, uncertainty-bearing, transition-dependent, learned/adaptive, or another materially different posture that the substrate did not already declare, reopen the substrate declaration instead of treating that posture change as view-only convenience.
