    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: A team has physical, mathematical and programming knowledge, but cannot connect the contributions needed to produce a physical result.
    • Question: Which missing contribution prevents the next engineering move?
    • First useful result or blocker: An interpreted calculation, proposed realization or located failure in the physical account, computation or execution.
    • Mantra: State the physical change sought. Construct the state and continuation needed to reason about it. Formulate the mathematical question and interpret its variables and operations. Obtain a result or computational procedure. Connect input preparation, system actions and output reading. Return to the physical question and repair the failed contribution.
    • Start with: B.5.MPC to connect available contributions and select the missing one. C.29 constructs mathematical correspondence; C.29.1 tests result transfer; C.29.2 constructs computation; C.29.3 connects it to an executing system. Subject engineering supplies physical laws and mechanisms.
    • Stop or return: Reuse ready contributions. Stop when the result suffices for the present decision. Reopen the contribution whose changed condition invalidates its use.

    Expansion for PHYSICAL-RESULT

    Divide the work. Give the next participant the result, what it denotes and the assumptions needed to use it. For the robot in B.5.MPC:5.1, the physical contribution supplies the motion model; the mathematical contribution relates distance to motor increments; the computational contribution produces an integer command and its rounding bound; the realization contribution checks what that command makes the controller do. People and AI agents can take these contributions according to their capabilities.

    Use A.3.3 to construct a missing state account and C.16 for a needed measurement relation. These are dependencies between results. A ready model or computation can be reused at its point of need. Slip can reopen the motion model, overflow the command representation, and changed timing the execution arrangement. A calculated displacement remains conditional on the model until actual motion is established.
