#A.2.9:10 — Rationale

Preface node heading:a-2-9-10-rationale:7680

#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 uses communicative acts both for ordinary receiving uses and as operationally meaningful events such as approvals, notices, and overrides. A.2.9 begins with who should understand or do what and the evidence needed for that use, then admits U.SpeechAct through the independent A.13/A.15.1 route when exact occurrence identity is current. F.6 follows only for a separate precise assignment-bound attribution. It treats each actual act as a temporally bounded Work individual enacting an exact Method and uses SpeechActRecord only for claim-bearing representation. This keeps performer, local agential kind and criterion, declared assignment species and occurrence, scope, working situation, window, conditional profile, recognition taxonomy, effective scheme, receiving claim scope, optional MethodDescription and channel, act interval, utterance descriptions, carriers, and separately governed effect intervals and deontic relations inspectable without mutual admission dependencies or letting a record stand in for actuality.

This also improves modularity:

• F.18 can remain a lexical entry point for naming (why “SpeechAct” and “utterance” are useful labels),
• while A.2.9 carries the ontology and conformance discipline for the kind, its actual occurrences, their optional records, and their connections to commitments, granted permissions, and evidence.
