#A.6.P:10 — Rationale

Preface node heading:a-6-p-10-rationale:12902

#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

Upper/foundational ontologies optimise for broad applicability via sparse commitments. FPF’s recurring, high-cost failures are often elsewhere: under‑specified relations in prose, where ambiguity hides in arity, kind selection, viewpoint, and change semantics.

A.6.P is orthogonal to “add a global taxonomy”:

• It provides a repeatable method to restore relational precision without requiring any external formalism or auxiliary authoring apparatus.
• It operationalises A.6’s boundary discipline by ensuring relation talk can be cleanly separated into signature invariants, admissibility, deontics, and evidence/work (A.6.B), rather than becoming one undifferentiated boundary claim.
