known_gaps:
  - Crash evidence depends on runtime, signal, exit code, core-dump policy, container restart policy, log retention, symbol availability, and whether the process died before flushing telemetry.
  - Diagnostic reports can contain environment variables, command-line arguments, file paths, loaded modules, and request context, so they require redaction before broad sharing.

## TL;DR

Crash evidence lets agents distinguish application exceptions, runtime faults, out-of-memory kills, signal exits, container restarts, and missing log retention.

## Core Explanation

An agent investigating a crash should not rely only on the final error message. The useful evidence is the process exit code, signal, runtime diagnostic report, previous container logs, stack trace, loaded modules, memory limits, restart count, and deployment version.

Diagnostic reports and fault handlers preserve context that ordinary logs may miss. They can show runtime version, thread state, stack frames, resource usage, and process arguments. In container platforms, previous logs and restart metadata are often the only evidence after a container has been replaced.

Agents should treat diagnostic artifacts as sensitive operational data. They should summarize the crash signature, redact secrets, and link the exact artifact or log window used for the conclusion.
