# Codex Crash Debug Report

**Generated**: $(date -Iseconds)
**Event ID**: $(echo "$meta" | jq -r '.eventId')
**Severity**: $(echo "$meta" | jq -r '.severity')

## Event Details

\`\`\`json
$meta
\`\`\`

---

## Files Collected

$(ls -lh "$debug_dir" | tail -n +2)

---

## System Information

- **OS**: $(uname -s)
- **Version**: $(uname -r)
- **Architecture**: $(uname -m)
- **Hostname**: $(hostname)
- **User**: $(whoami)

---

## Git Information

- **Branch**: $(git branch --show-current 2>/dev/null || echo "N/A")
- **Commit**: $(git rev-parse HEAD 2>/dev/null || echo "N/A")
- **Worktree**: $(git worktree list --porcelain 2>/dev/null | grep '^worktree' | head -1 | cut -d' ' -f2 || echo "none")

## Next Steps

1. Review logs in this directory
2. Check \`git-diff.txt\` for uncommitted changes
3. Examine \`stdout-tail-200.log\` and \`stderr-tail-200.log\` for error patterns
4. Verify system resources in \`memory-usage.txt\` and \`disk-usage.txt\`
