[self-care:open-source-failures] Repair repeated safe-output processing failures in Dev Practices / Well-Architected

`githubnext/gh-aw-cao` is repeatedly failing during safe-output processing for `Dev Practices / Well-Architected`. The bounded seven-day snapshot shows 5 runs failing at the same `safe_outputs` step, so downstream write handling is unstable even after agent work completes.

**Action:** the workflow owner should inspect the safe-output payload and processor logs for `Dev Practices / Well-Architected`; accept when at least one new run completes the `Process Safe Outputs` step successfully and the repeated failure pattern stops.

Critical findings:
- Representative run: https://github.com/githubnext/gh-aw-cao/actions/runs/33939650717
- Affected workflow: `.github/workflows/software-development-practices-github-well-architected.lock.yml`
- Repeated signature: job `safe_outputs`, step `Process Safe Outputs`
- Probable cause: more evidence is required. The bounded snapshot confirms repeated processor-stage failure but does not include the processor error needed to distinguish invalid payloads from sink-side processing faults.
- Confidence: medium.

Agent prompt
Inspect recent runs of `.github/workflows/software-development-practices-github-well-architected.lock.yml` that failed in `safe_outputs` at `Process Safe Outputs`. Identify the concrete processor error, trace it to the workflow's emitted safe-output payload or routing configuration, make the smallest fix that restores successful processing, and summarize the root cause plus the verification run.

Start with .github/workflows/software-development-practices-github-well-architected.lock.yml and the Process Safe Outputs step in representative run 33939650717. Inspect the safe-output payload, processor logs, and routing configuration to identify the concrete failure. Done means a new run completes Process Safe Outputs successfully and the repeated failure pattern stops.
