    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

    FPF uses source traditions for particular answers and states the adopted contribution in the subject pattern. The following connections explain why several families work together. The direct bodies retain the precise source editions, stronger technical conditions and refresh triggers.

    Constructional ontology contributes a demand to explain constituents, construction and identity. A.1 adapts Florio and Linnebo's construction-sensitive account and the applied choices discussed by Borgo and Righetti; it keeps part relations and whole recognition explicit instead of importing an external category system wholesale. B.1.5 carries the corresponding question into Method composition and also adapts scoped-effect and protocol work: usable joins depend on preconditions, order, boundary interactions and failure routes. This combination helps a reader test a proposed whole while keeping its diagram and description separately inspectable.

    Measurement and assurance supply different parts of an evidence-based answer. C.16 adopts the JCGM VIM result boundary and adapts GUM measurement-model discipline so that the reported value, relevant information, assumptions and uncertainty can be recovered. B.3 adapts the claim-argument-evidence structure of ISO/IEC/IEEE 15026-2 and GSN to the particular reliance question. Its dependence-sensitive calculation also rejects a universal weakest-link arithmetic. Together they let the report-review team ask both what a time value means and how far the trial supports the proposed use. The measurement source supplies no release authority; that question has its own participant and governing rule.

    Open-ended search and sequential decision research explain why exploration is kept beside assurance. C.18 uses quality-diversity research to distinguish retained alternatives, current fronts and generation of further possibilities; its source account states the limits of inferring useful exploration from archive occupancy. C.19 draws on bandit and Bayesian-optimization work for explicit cost, uncertainty and policy-change pressures. FPF keeps those contributions while leaving the actual algorithm and domain evaluator to their justified use. An attractive archive or one high novelty value does not establish the usefulness of the next experiment.

    The synthesis is use-specific: construction explains what whole is proposed, measurement makes a relevant observation interpretable, assurance qualifies reliance, and search preserves alternatives or asks for another result. A successor source matters when it changes one of those answers. G.11 returns the affected use to that source; E.19 and E.23 support preservation and improvement of the resulting pattern content. This lets stronger knowledge change the framework without requiring every unaffected practitioner result to be obtained again.
