Distributed Debugging Debug Trace

This one's for when you need to set up proper observability across multiple services and actually understand what's happening in production. It walks you through configuring distributed tracing, standardizing your logging with correlation IDs, and establishing debugging workflows that work for both local dev and live systems. The focus is on trace boundaries, span coverage, and making sure you're not dumping sensitive data into your logs. It's overkill if you're debugging a single process app, but if you're dealing with microservices or need to track requests across service boundaries, it gives you a solid framework for getting trace instrumentation right without shooting yourself in the foot with verbose production logging.
