    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

    • Exactly one governing definition per DefaultId.
    • Any other mention in G.x MUST be a citation/delegation to the governing definition, not a competing statement.
    • A default may be conditional (default-rule) with explicit applicability conditions.
    • The Default Governing Definition Index SHALL NOT be used to “smuggle” mandatory invariants as defaults. Invariants remain invariants (typically cited through CC‑GCORE‑… and their canonical governing definitions).
