Fluent Refactoring
summary
Refactors a messy 50-line Rails controller method by actually changing code not theory: extracts a method object (replace method with method object), uses a temporary method_missing hack to keep tests green, applies flatten nested conditionals to expose a guard clause, extracts five private helpers, moves HTTP concerns into a responder pattern, then splits that into Ajax and HTML responders (replace conditional with polymorphism) and eliminates duplicated xhr checks; tests run green throughout and the refactor reduces noise and duplication.
