Architectural Prevention & Performance Tuning Checklist
- Always specify `--wait-for-output` in automated pipelines to prevent race conditions.
- Extract job metadata via `--response-format-json` and parse with `jq` for robust error handling.
- Archive spool outputs as build artifacts in GitHub Actions / GitLab for post-mortem analysis.
