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

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 → Deontics & Commitments layer: atomic governance claims that state an accountable duty, recommendation-as-duty, prohibition, or commitment. When permission wording is live, §8.4.1 decides whether its claim also belongs here.
- E → Work-Effects & Evidence layer: truth-conditional claims whose satisfaction requires actual work, evaluation, observation, or produced carriers.
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.
