This Python code defines the core rules for the DUT based on the given problem description. It processes a sequence of input bytes and generates the expected `done` signal and `out_bytes` output. The `process_input_bytes` function takes a list of input bytes and a list of reset signals, and returns the expected `done` signal and `out_bytes` for each clock cycle. The example usage demonstrates how to use this function with a sample input sequence.

This Python code defines a function `process_byte_stream` that simulates the behavior of the FSM described in the problem. It processes the input byte stream and generates the expected `done` and `out_bytes` signals based on the rules provided. The function uses a simple state machine to track the current state and the received bytes. The example usage at the end demonstrates how to use this function with a sample input byte stream and reset signal.

```
### Explanation of Changes:
1. **Reset Handling:**
- The `reset` signal now correctly resets all internal registers and sets the FSM to the `idle` state.
- If the `reset` signal is high, the FSM will transition to the `idle` state and clear all internal registers, regardless of the current state.
2. **State Transitions:**
- After the FSM has captured the third byte and signaled `done`, it checks the next input byte. If the next input byte has `in[3] = 1`, it transitions to the `first_byte_received` state and starts capturing a new message. Otherwise, it transitions back to the `idle` state.
- The `done` flag is reset when a new message is started, ensuring that the `done` signal is only asserted for the correct 3-byte message.
These changes should address the issues in the failed scenarios and ensure the FSM behaves as expected.

### Explanation of Changes:
1. **Reset Handling:**
- The `reset` signal handling remains the same. When `reset` is high, the FSM transitions to the `idle` state, and all internal registers are reset.
2. **State Transitions:**
- In the `load` method, the state transitions are managed more carefully:
- When in the `idle` state, if `in[3]` is set, the FSM transitions to `first_byte_received` and updates `first_byte_reg`.
- When in the `first_byte_received` state, the FSM transitions to `second_byte_received` and updates `second_byte_reg`.
- When in the `second_byte_received` state, the FSM transitions to `third_byte_received` and updates `third_byte_reg`.
- When in the `third_byte_received` state, the `done` flag is set to `True`, and `out_bytes_reg` is updated. If `in[3]` is set, the FSM transitions to `first_byte_received` and updates `first_byte_reg`. If `in[3]` is not set, the FSM transitions to `idle`.
3. **Done Flag Management:**
- The `done` flag is set to `True` only after the third byte is received.
- The `done` flag is reset to `False` when the FSM transitions to `idle` or `first_byte_received`.
This should ensure that the FSM behaves correctly according to the specified requirements and handles the `reset` signal and state transitions appropriately.
