A.2.9:4.1 — Normative definition

U.SpeechAct <: U.Work is a kind declaration. An actual Work individual is admitted as SA : U.SpeechAct when its primary effect is communicative: it places an utterance through an optional channel in a way classified by an exact speech-act recognition taxonomy under an effective reference scheme and, when institutional force is claimed, by a current policy, procedure, or protocol rule as potentially:

asserting/informing,
requesting/directing,
promising/committing (as an instituting act),
declaring/authorizing/revoking (status-changing acts),
notifying (event announcement relevant for downstream work).

Per A.7 and A.15.1, the actual speech-act occurrence is a Work individual; its SpeechActRecord and utterance descriptions are epistemes, while its carriers are utterance carriers, publication carriers, or traces that allow observation and audit.

Occurrence identity specializes A.15.1. Admit a candidate as actual communicative Work from one exact communicative performance history, every actual performer’s A.13 core, an enacted Method, temporal extent, and containing-System relation; do not use an F.6 conclusion as an admission premise. Several satisfied act types classify that one Work occurrence. Identify more than one occurrence only when distinct performance history, enacted Methods, institutional actions, or another admitted discriminator establishes distinct Work. A shared utterance, carrier, assignment, or interval decides neither sameness nor difference. If a named use still admits more than one defensible segmentation, cite its continuity or segmentation rule or leave the occurrence boundary unresolved. Check any precise assignment-bound attribution through F.6 only after admission.

Whether a given act type institutes commitments, permissions, publication relations, or status changes depends on an exact current policy or procedure and on the direct obtaining conditions of the claimed effect. Absent that basis, treat SA : U.SpeechAct only as actual communicative Work.
