    A.6.C:4.3 — “Guarantee” disambiguation

    Preface node heading:a-6-c-4-3-guarantee-disambiguation:13280

    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 “guarantee” leaves a consequential ambiguity, use the applicable distinction below:

    • Semantic guarantee → L (“by definition or invariant”).
    • Runtime-entry guarantee → A (“the mechanism admits this application iff …”).
    • Governance guarantee → D (“provider commits or implementer must”).
    • Operational result → E (the exact Work, evaluation, or observation and its measured or evaluated result; add an A.10 evidence path and exact carrier when the receiving decision relies on that support).

    If none of these fits, the statement is likely rhetorical and should be rewritten or explicitly marked as aspirational or informative.
