-### Scope
-
-Implement:
-- `spoken_word` module package.
-- Spoken-word prompt builder ported from Python.
-- Spoken-word structured response model.
-- Spoken-word replacement policy.
-- Spoken-word confidence threshold handling.
-- Spoken-word validator chain.
-- Strong semantic guardrails using LLM-backed validators.
-- Prompt/response diagnostics.
-- CLI support for `--modules spoken_word`.
-- Fake LLM tests.
-- Tests for rejection of meaning-changing cleanup.
-
-Do not implement:
-- Prompt redesign beyond faithful porting.
-- New stylistic rewriting behavior not present in the Python implementation.
-
-### Expected behavior at end of phase
-
-Running `audita process ... --modules spoken_word` should perform real conservative dysfluency cleanup, with guardrails against semantic changes.
-
-### Definition of done
-
-- Spoken-word module runs in the production runner.
-- Spoken-word proposals are generated through structured LLM calls.
-- Semantic validators reject meaning-changing proposals.
-- Applied/skipped spoken-word changes appear in reports.
-- Prompt/response diagnostics are written.
-- `go test ./...` passes without requiring external LLM credentials.
+Not implemented in Phase 15 (by design):
+- Full default module sequence execution as a feature-complete claim.
