Review the provided Java code snippet for the LegacyOrderProcessor module, which is a critical part of a legacy system with no existing tests. Identify at least 5 distinct code smells. For each identified smell, you must:

1. Clearly name and describe the code smell.
2. Explain its negative implications on the system (e.g., maintainability, testability, extensibility, understandability, refactoring difficulty, debugging complexity).
3. Reference specific lines or sections of the provided code that exemplify the smell.

Based on your analysis of the LegacyOrderProcessor and considering the critical nature of the module with no existing tests, propose a comprehensive, step-by-step refactoring strategy. Your strategy must explicitly address the following:

• Risk Mitigation: How will you safely refactor a critical module without existing unit tests? Discuss specific techniques (e.g., characterization tests, micro-commits, IDE refactoring tools).
• Incremental Nature: Outline a logical sequence of refactoring steps, emphasizing an incremental approach rather than a 'big bang' rewrite.
• Prioritization: How would you prioritize the refactoring steps based on impact, safety, and enabling further changes?
• Design Pattern Application: Propose the application of at least two relevant Gang of Four (GoF) design patterns to improve the module's design, maintainability, and testability. For each chosen pattern:
  • Explain why it is suitable for this specific context.
  • Describe how it addresses one or more of the code smells you identified in Part 1.

Using the refactoring strategy and design patterns you proposed, write pseudo-code (or high-level Java-like code) for a significantly refactored, more modular, and highly testable version of the LegacyOrderProcessor.processOrder logic.

Your pseudo-code should clearly demonstrate:

1. The application of your proposed refactoring steps and design patterns.
2. How the new structure inherently supports unit testing and mockability.

Finally, provide a brief conceptual example (not full code, but highlighting key aspects) of how a unit test for one of your refactored components would look, emphasizing its simplicity and isolation compared to attempting to test the original monolithic code.
