#A.6.B:6.2 — Canonical cross‑quadrant dependency patterns

Preface node heading:a-6-b-6-2-canonical-cross-quadrant-dependency-patterns:8955

#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) Duty-to-gate linkage

When governance requires someone to comply with a gate:

• D-*: “Role MUST satisfy or enforce A-*.”

This separates what is admissible (A) from who is responsible (D).

#(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) Duty-to-evidence linkage

When governance requires evidence production, retention, or exposure or commits to measured properties:

• D-*: “Role MUST retain or expose carrier class C used by E-* …”
• D-*: “Provider SHALL meet E-* under exclusions …”

This separates obligation or commitment (D) from 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 an obligation or commitment 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.
