    A.6.B:4.3 — Canonical placements in the Signature Stack

    Preface node heading:a-6-b-4-3-canonical-placements-in-the-signature-stack:8829

    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

    The quadrants have canonical placements in the boundary stack:

    • L → Signature layer: U.Signature.Laws (and mechanism‑local semantic laws if present).
    • A → Mechanism layer: U.Mechanism.AdmissibilityConditions (entry gates / runtime admissibility predicates).
    • D → Norms & commitments layer: role-bound duties, commitments, publication and accountability duties (often rendered inside MVPK TechCard).
    • E → Evidence bindings layer: work‑adjudicated effects tied to carriers and measurement conditions (authored canonically in an Evidence-and-carriers section; commonly rendered inside MVPK AssuranceLane as a projection).

    A published view MUST NOT introduce new semantic claims outside this L/A/D/E-classified claim set. E.17 (MVPK) is a specialization that enforces this rule for a fixed set of publication face kinds.
