#A.2.9:10 — Rationale

Preface node heading:a-2-9-10-rationale:5672

#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

FPF already relies on communicative acts (approvals, notices, overrides) as operationally meaningful events, but without a kernel object they blur into examples, naming choices, or prose. A.2.9 anchors speech acts where they belong: as a Work-kind with explicit performer, scope, and time, and with disciplined links to utterance surfaces, carriers, and deontic bindings (U.Commitment).

This also improves modularity:

• F.18 can remain a lexical anchor for naming (why “SpeechAct/utterance” as a label family is useful),
• while A.2.9 carries the ontology and conformance discipline for how speech acts behave as objects and how they connect to commitments and evidence.
