    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

    A boundary description is evolvable iff its claims are separated across the signature stack and each statement is classified by the boundary discipline matrix to its proper layer (Laws, Admissibility, Deontics and commitments, Effects and evidence), while preserving EntityOfConcern and Description-episteme / publication-carrier separation.
