Save Developer Session Progress

Problem/Feature Description

You have been helping Priya, a backend engineer, debug a performance regression in her team's e-commerce API. After several hours of investigation together, the two of you have traced the slowdown to an N+1 query problem inside ProductController#index (file: app/controllers/product_controller.rb, line 47). The culprit is a Product.all call followed by individual product.reviews.count calls inside a render loop. The fix is to add eager loading via includes(:reviews) and update the associated controller test in spec/controllers/product_controller_spec.rb.

Priya has to leave for the day before the fix is applied. She asks: "Can you save where we are? I want to be able to pick up exactly where we left off tomorrow morning without losing the thread."
