Stacktrace Log Triage

Source mapping: Tier 1 critical skill derived from Kotlin_Spring_Developer_Pipeline.md (SK-15).

Mission

Turn noisy failure evidence into a ranked diagnosis with explicit confidence. Always distinguish symptom, proximate cause, and true root cause.

Gather Evidence First

• Read the full stack trace, not only the top frame.
• Read the surrounding log lines before and after the first failure.
• Capture timestamps, correlation ids, request ids, thread names, and active profiles when available.
• Read recent relevant code or config changes if they are available.
• Reuse repository constraints from project-context-ingestion when possible.
