  // ---------------------------------------------------------------------------
  // COMPLETE CASE
  //
  // Every IXApplication interface (e.g. IAutoBeRealizeCollectorWriteApplication,
  // IAutoBeInterfaceEndpointWriteApplication, IAutoBeDatabaseSchemaApplication,
  // etc.) exposes a single `process()` whose `request` parameter is a
  // discriminated union:
  //
  //   request: IWrite                        — submit generated artifacts
  //          | IAutoBePreliminaryGet*         — incremental RAG data loading
  //          | IAutoBePreliminaryComplete     — finalize the loop
  //
  // The LLM sends `{ type: "complete" }` when it believes the cyclinic
  // write → validate → correct loop is finished. However, LLMs frequently
  // attempt to call complete() prematurely — before ever submitting a write —
  // especially when the context window is thin or when exhausted preliminary
  // types are removed from the union, leaving only `complete` as a seemingly
  // valid choice.
  //
  // To guard against this, we check `controller.getPreviousWrite()`:
  //
  //   - Prior write EXISTS  → validate the `IAutoBePreliminaryComplete`
  //     structure via typia and allow finalization.
  //   - NO prior write      → reject with an explicit error instructing the
  //     LLM to submit its write first before requesting completion.
  //
  // @see IAutoBePreliminaryComplete       — shared completion request structure
  // @see AutoBePreliminaryController      — orchestrate() loop that consumes
  //                                         the completed flag
  // @see orchestratePreliminary           — sets completed.value when
  //                                         confirm === true
