**What was implemented**  
The original project used a special *reflect* node to retry answer generation.  
In this version the retry logic is replaced by a plain `try/except` loop inside  
`get_answer_with_retry`. The function now attempts to call a generator up to
`max_retries` times, sleeping a short back‑off between attempts, and raises a
`GenerationError` only after all attempts fail.

**Why the main parts satisfy the assignment**  
* The retry mechanism is implemented without any external node – it is a
  self‑contained loop that catches any exception from the generator and
  retries.  
* The number of attempts and back‑off are configurable, matching the
  behaviour that the original *reflect* node provided.  
* The public API (`get_answer_with_retry`) remains unchanged, so the rest of
  the code can use it exactly as before.

**Key code excerpts**

*`src/index.py` – retry loop*  
```python
while attempt < max_retries:
    try:
        answer = generator()
        return answer
    except Exception as exc:
        attempt += 1
        if attempt >= max_retries:
            raise GenerationError(
                f"Answer generation failed after {max_retries} attempts"
            ) from exc
        wait_time = backoff_factor * attempt
        time.sleep(wait_time)
```

*`src/index.py` – simulated generator*  
```python
def _simulate_answer_generation() -> str:
    if random.random() < 0.3:
        raise RuntimeError("Simulated generation failure")
    time.sleep(0.1)
    return "Generated answer content"
```

*`src/index.py` – entry point*  
```python
def main() -> None:
    try:
        answer = get_answer_with_retry()
        print("Answer generated successfully:")
        print(answer)
    except GenerationError as err:
        print(f"Error: {err}")
```

**Limitations**  
* The generator is a simple simulation; in a real system it would be replaced
  by the actual answer‑generation logic.  
* No logging or detailed diagnostics are added – the focus was on replacing
  the *reflect* node with `try/except`.  
* The back‑off is linear; exponential back‑off could be added if needed.

Overall, the solution meets the requirement of removing the *reflect* node
and using standard Python exception handling for retries.
