## TL;DR

Correlation IDs and trace context let agents connect logs, traces, requests, jobs, and downstream failures into one incident timeline.

## Core Explanation

Agents investigating production behavior need stable join keys. Request IDs, trace IDs, span IDs, job IDs, and deployment IDs let the agent move from a user-visible error to the relevant log lines, spans, retries, queue messages, and downstream calls.

Trace context is especially important across services. If the context is dropped at an HTTP boundary, queue boundary, or background job handoff, the agent may see separate fragments instead of a single causal path. The useful diagnostic question is not only "what failed" but also "which correlated request path proves it failed".
