The modified test above adds expect(getModeBySlug).toHaveBeenCalledWith("code", []) to catch a mode-source mutation, but this test does not have the equivalent. getModeBySlug is mocked to return undefined for any input, so passing state.mode ("code") instead of taskMode ("missing") would still produce toBeUndefined() passing. Worth adding expect(getModeBySlug).toHaveBeenCalledWith("missing", []) here?

The three happy-path tests (lines 155, 179, 297) use this getTaskMode default alongside mockGetState → { mode: "code" }, so both sources return the same value. A mutation that reads state.mode instead of task.getTaskMode() for the "from" label would still produce "Successfully switched from Code mode…" and pass — only the test at line 330 (architect case) catches it. Would it help to set mockGetState to { mode: "orchestrator" } in those three tests?
