[self-care:open-source-failures] Open-source failures digest for 2026-09-06 snapshot

Snapshot 2026-09-06T04:05:46.218Z covered the latest 7 days across 7 public projects and found 672 failed runs in the bounded activity snapshot. The newest 100 failed runs available here cluster into two recurring P1 defects in `githubnext/gh-aw-cao`, both currently unverified against existing issue coverage because repository issue listing failed in this run.

**Action:** CAO maintainers should review the two remediation issues from this snapshot, decide whether either supersedes an existing tracker, and accept when duplicate coverage is closed or linked and an owner is assigned for the active defect.

Critical findings:
- 2 actionable P1 clusters were evidenced in the bounded snapshot; 0 P0 clusters were evidenced.
- Cluster 1: repeated live-mode pre-activation failures reporting missing target authority across AW Doctor and Dependabot workflows in `githubnext/gh-aw-cao`.
- Cluster 2: repeated `safe_outputs` job failures during `Process Safe Outputs` in `Dev Practices / Well-Architected` in `githubnext/gh-aw-cao`.
- The snapshot is truncated, so older failures outside the newest 100 failed runs were not available for clustering.
- Existing issue coverage could not be verified because `gh issue list` failed with platform errors during this run.

Prioritized remediation list

1. `githubnext/gh-aw-cao` — live-mode workflows blocked by missing target authority (`Run CAO control precompute` / `Target authority missing: add .github/workflows/cao.json to the target default branch for live mode`) — P1, recurring across multiple workflows.
2. `githubnext/gh-aw-cao` — `Dev Practices / Well-Architected` fails in `safe_outputs` / `Process Safe Outputs` — P1, recurring across multiple runs.

Cluster summary

- P0: 0
- P1: 2
- P2: not exhaustively summarized because the evidence window was truncated to the newest 100 failed runs and many remaining failures were insufficiently evidenced.
- Existing coverage confirmed: unknown
- Existing coverage blocked by: `gh issue list` failed (`malformed version`, timeout, then `HTTP 502: resource labeling failed`)

Start by reviewing the representative AW Doctor, Dependabot, and Dev Practices / Well-Architected runs linked in the issue, along with the target repository's .github/workflows/cao.json coverage. Confirm whether the missing target authority and safe_outputs failures duplicate existing issues; done means duplicate coverage is linked or closed and an owner is assigned for any active defect.
