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

A U.SpeechAct is a U.Work occurrence whose primary (intended) effect is communicative: it places an utterance into a context in a way that is recognized by that context’s institutional semantics (policies, procedures, protocol rules) 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, U.SpeechAct is an object/event; its utterance descriptions are descriptions (epistemes/spec clauses/messages‑as‑content), and its carriers are utterance carriers, publication carriers, or traces that support observation and audit. (Note: “Surface” is reserved for MVPK publication/interoperability surfaces; do not use it here.)

Whether a given actType institutes commitments/permissions/status changes is entirely context‑policy dependent. Absent an explicit policy, treat a U.SpeechAct as a communicative Work occurrence with observable provenance only; do not infer deontic bindings from the act by default.
