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

`Dev Practices / Well-Architected` in `githubnext/gh-aw-cao` failed 5 times in the bounded snapshot at the `Process Safe Outputs` step, indicating a recurring post-agent output handling break rather than a one-off run blip. The evidence supports a workflow-level safe-output processing fault, but not the deeper root cause from this snapshot alone.

**Action:** The workflow maintainer should assign this issue to Copilot to inspect the safe-output contract for `.github/workflows/software-development-practices-github-well-architected.lock.yml` and its editable source, then accept when a fresh run completes past `Process Safe Outputs` and the next snapshot shows no new failures with the same signature.

Critical findings:
- 5 recurrent failures shared the same strongest signature: `Process Safe Outputs`.
- Representative run: https://github.com/githubnext/gh-aw-cao/actions/runs/34036249743
- Additional corroborating runs: https://github.com/githubnext/gh-aw-cao/actions/runs/34036239338, https://github.com/githubnext/gh-aw-cao/actions/runs/34036229335, https://github.com/githubnext/gh-aw-cao/actions/runs/34036220174, https://github.com/githubnext/gh-aw-cao/actions/runs/34036210648
- Confidence: medium for the cluster; bounded snapshot does not reveal the underlying payload or validation error.

Agent prompt
Inspect the editable workflow source and generated lock for the Dev Practices / Well-Architected workflow, trace every declared safe-output emitted by the run, and fix the smallest contract or payload mismatch that can cause the `Process Safe Outputs` step to fail. Preserve fail-closed behavior, do not widen authority or mode, recompile lock files from Markdown sources if needed, and validate with the narrowest relevant tests plus `npm run compile`.

Evidence

- Workflow: `.github/workflows/software-development-practices-github-well-architected.lock.yml`
- Cluster signature: `Process Safe Outputs`
- Run count in bounded snapshot: 5
- Representative run URL: https://github.com/githubnext/gh-aw-cao/actions/runs/34036249743
- Probable cause: safe-output processing failure in this workflow path; more detailed root-cause evidence requires inspecting the run logs outside this bounded snapshot.

Start by inspecting the five linked workflow runs and the safe-output contract in .github/workflows/software-development-practices-github-well-architected.lock.yml and its editable source. Trace each declared safe output, run the narrowest relevant tests, and run npm run compile. Done means a fresh run passes Process Safe Outputs and the next snapshot has no failures with the same signature.
