 - Service source surfaces now use semantic `WorkflowService` in the implementation, local factory, presentation layer, runtime probe scripts, and active tests; the temporary `KapiService` export has been removed after migrating the large remaining test clusters.
 - Presentation registration/UI action helpers now use semantic workflow names (`registerWorkflowExtension`, `registerWorkflowCommandsAndTools`, `registerWorkflowTools`, `WorkflowUiActionContext`, `installWorkflowAutocomplete`, `toggleWorkflowWidgetExpanded`) while leaving public `kapi_*` tool names and `/kapi-*` contracts intact.
 - Adapter/domain private helper names now use semantic state/workflow naming for symlink guards, managed autoresearch symlinks, worker branch validation, and prompt rule rendering while preserving user-facing Kapi contract text.
+- Review gate helper exports now use semantic review-gate names (`ReviewGateInput`, `ReviewGateResult`, `buildReviewGate`, `runReviewGateCli`, `parseReviewGateArgs`, `REVIEW_GATE_MAX_CHANGED_LINES`) while preserving the `kapi-review` CLI and `kapi-agent` review contract text.
