Overview

Rack Middleware: Final safety net for uncaught errors This catches errors that somehow escape controller error handling Positioned at the Rack layer (outermost layer of Rails)

Middleware stack order (outer to inner):

  1. ErrorCatcher (this file) ← Catches everything

  2. ActionDispatch middleware

  3. Rails routing

  4. Controllers (with ErrorHandler concern)

This ensures NO error goes unreported
