Refactoring Rails
summary
Implements nested through associations in Rails 3 by turning association reflections into linear chains (recursing to leaf reflections) and generating identical SQL joins for different association shapes; splits the collection proxy from the association (avoiding method_missing recursion), replaces a tangled preload module with an object hierarchy using polymorphism and single-responsibility, fixes many Lighthouse-reported bugs and adds tests. Patch complexity drops from +342 lines to +94 lines and the feature merges after ~6 months.
