Yes. Your previous query was "write tests for todo.py", and it's done: test_todo.py has six tests covering `add_todo` (append with `done: False`, ordering) and `complete_todo` (marks done, leaves others alone, raises on missing, first-match-only on duplicates). All six pass under pytest.

The earlier queries were handled too: `add_todo` written, `complete_todo` added (with the dict-based `{"text", "done"}` representation), and the state-storage explanation delivered. Nothing is pending on my side; let me know if any of those answers didn't reach you and I'll resend the details.
