Solution Details

class Tracker:
    def __init__(self):
        # Initialize self.context to hold state data. 
        # It should include tokens for token tracking logic.
        self.context = {"tokens": []}

    def process_token_input(self, user_id, is_system_message, delta_tokens):
        """
        Processes new token input and updates the context state.
        Handles potential KeyErrors if 'tokens' is missing in self.context.
        """
        # FIX: Use .get() to safely retrieve "tokens", providing an empty list [] 
        # as a default value if the key does not exist, preventing KeyError.
        current_tokens = self.context.get("tokens", [])
        new_context = {"tokens": current_tokens + delta_tokens}
        self.context.update(new_context)
        return new_context

    def get_context(self):
        return self.context

# Example usage structure (assuming this is the context of temp_verification.py)
if __name__ == "__main__":
    tracker = Tracker()
    
    # Simulate first call (where KeyError might have occurred if not fixed)
    print("--- First Call ---")
    event1 = tracker.process_token_input(5, False, ["token_a", "token_b"])
    print(f"New Context: {event1}")

    # Simulate subsequent call
    print("\n--- Second Call ---")
    event2 = tracker.process_token_input(5, True, ["token_c"])
    print(f"New Context: {event2}")
