Adding CLAUDE.md with task information for AI processing. This file will be removed when the task is complete. Issue: #1171
- Downloaded and preserved original log (13,956 lines) from Gist - Created comprehensive timeline reconstruction of termination events - Identified root cause: SIGTERM signal received from external source - Documented exit code 144 was from bun test subprocess, not solve.mjs - Added recommendations for improved signal handling and logging - Included signal reference table and related resources Key finding: The solve.mjs process was gracefully terminated by SIGTERM after ~36 minutes of execution while the AI was actively working on fixing issue #131 (Agent CLI stderr/stdout issue).

Summary
Case study analysis for understanding why the solve.mjs process was terminated unexpectedly.
Key Findings
Root Cause: The solve.mjs process received a SIGTERM signal (signal 15) from an external source after ~36 minutes of execution.
Exit Code Clarification: The exit code 144 mentioned in the log came from the
bun testsubprocess (128 + 16 = signal 16), not from solve.mjs itself.Termination Sequence:
20:06:14.681Z- Cleanup function triggered (SIGTERM received)20:06:14.875Z- Last TaskOutput result received (exit code 144 from bun test)20:06:14.976Z- "Terminated" message logged, process exitsWork in Progress: At termination time, the AI was actively running tests to verify fixes for issue When hive.mjs executes solve.mjs actual commands with
./solve.mjs ...should be logged #131 (Agent CLI stderr/stdout output issue).Files Added
docs/case-studies/issue-1171/analysis.md- Comprehensive analysis document with timeline, root cause, and recommendationsdocs/case-studies/issue-1171/original-log.txt- Complete original log (13,956 lines) preserved from GistRecommendations
