[self-care:open-source-failures] Shared safe-output processing failures are recurring across multiple workflows

Multiple `githubnext/gh-aw-cao` workflows are reaching `Process Safe Outputs` and then failing repeatedly, which suggests a shared publishing-path defect after analysis completes. In the bounded snapshot, 10 failures across 3 workflows share this exact step-level signature.

**Action:** CAO maintainers should inspect the shared safe-output publishing path used by the affected workflows and ship the smallest fix that lets those runs complete; accept when reruns of the affected workflows no longer fail in `Process Safe Outputs`.

Agent prompt
Investigate the repeated `Process Safe Outputs` failures affecting `Dev Practices / Well-Architected`, `SelfCare / Data Acquisition Audit`, and `SelfCare / Dashboard Performance`. Trace the common safe-output path, identify the first shared defect that can explain these post-analysis failures, implement the narrowest fix, add regression coverage if the repo has a suitable test seam, and document how a rerun proves the fix.

Critical findings:
- Repository: `githubnext/gh-aw-cao`
- Cluster severity: P1
- Normalized signature: `Process Safe Outputs`
- Affected workflows: `Dev Practices / Well-Architected`, `SelfCare / Data Acquisition Audit`, `SelfCare / Dashboard Performance`
- Run count in bounded snapshot: 10
- Representative run: https://github.com/githubnext/gh-aw-cao/actions/runs/33963403527
- Confidence: medium
- Probable cause: more evidence is required for the exact defect, but the recurrence across multiple workflows indicates a likely shared problem in safe-output processing rather than a single workflow-specific analysis failure.

Representative evidence

- `Dev Practices / Well-Architected`: https://github.com/githubnext/gh-aw-cao/actions/runs/33963403527
- `SelfCare / Data Acquisition Audit`: https://github.com/githubnext/gh-aw-cao/actions/runs/33963457581
- `SelfCare / Dashboard Performance`: https://github.com/githubnext/gh-aw-cao/actions/runs/33963453396

Each enriched run failed in job `safe_outputs`, step `Process Safe Outputs`. The bounded snapshot did not include deeper logs or an error message for the underlying cause.

Start with the safe_outputs job and its Process Safe Outputs step in the affected workflows: Dev Practices / Well-Architected, SelfCare / Data Acquisition Audit, and SelfCare / Dashboard Performance. Inspect the representative run logs and trace the shared safe-output publishing path; done means reruns of the affected workflows complete without failing at that step.
