## AI overview

Blueground Engineering's guide explains the role of logs in observability and recommends using them primarily as a forensic tool for investigating failures. It discusses reconstructing timelines, preserving context, identifying root causes, validating system behavior, and making structured logs useful to LLMs and AI-assisted incident analysis.
