You are a Lead Developer tasked with refactoring a 10-year-old monolithic Java application (The 'Legacy Beast') characterized by 'God Objects' and tight coupling. Outline a 6-month refactoring roadmap. Your plan must prioritize the 'Strangler Fig' pattern. For each phase (Months 1-2, 3-4, 5-6), specify exactly which components you would extract first (e.g., authentication, reporting) and justify your choice based on risk minimization and business value. Additionally, explain how you would maintain continuous integration and delivery during this transition.
