    Preface node heading:a-6-b-6-2-canonical-cross-quadrant-dependency-patterns:11327

    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

    These patterns are valid (and common). The square becomes operational when these links are used systematically.

    (D → A) Prescription-or-duty-to-gate linkage

    When governance says that a gate must be satisfied or enforced:

    • generic D-*: “Policy-P requires covered subjects to satisfy or enforce A-*”; or
    • individual D-*: “Actual bearer S has commitment C to satisfy or enforce A-*.”

    This separates what is admissible (A) from generic normative content and any separately instituted individual duty (D). If responsibility is also claimed, state its admitted direct domain predicate or exact missing governor rather than inferring it from the duty.

    (E → A) Evidence-for-gate linkage

    When gate decisions must be observable:

    • E-*: “On rejection or acceptance due to A-*, carrier C is produced or observable under conditions …”

    This separates gate semantics (A) from evidence semantics (E).

    (D → E) Prescription-or-duty-to-evidence linkage

    When governance prescribes evidence production, retention, exposure, or a measured property:

    • generic D-*: “Policy-P requires covered subjects to retain or expose carrier class C used by E-* …”; or
    • individual D-*: “Actual bearer S has commitment CMT to meet E-* under exclusions …”

    This separates a generic prescription or individual duty (D) from its adjudication (E).

    (A/E → L) Semantic grounding linkage

    When a gate predicate or measurement relies on definitions or invariants:

    • A-* / E-* references L-* that define terms or metrics.

    This prevents “metric drift” and “definition drift” across views.

    (D → L) Governance-to-definition linkage

    When a generic prescription or individual obligation relies on precise term or metric meanings:

    • D-* references L-* that define the terms or metrics it uses.

    This keeps governance text from accidentally redefining semantics in prose.
