Problem Statement
When would you prefer Template Method over Strategy for request validation pipelines?
Explanation
Choose Template Method when the high-level algorithm is stable and you need fixed steps with small overridable hooks. Subclasses change only the hook points while the skeleton stays in the base.
Choose Strategy when entire algorithm variants need swapping at runtime, not just small differences. Strategy keeps composition flexible, while Template Method relies on inheritance.
