[self-care:open-source-failures] Open source failures digest for 2026-09-05 snapshot

Snapshot 2026-09-05T07:00:02Z covering the last 168 hours found 1,222 failed runs across 7 public projects. The highest-confidence untracked problems are repeated live-mode target-authority failures in `githubnext/gh-aw-cao`, repeated activation artifact upload failures in `githubnext/gh-aw-workshop`, and repeated safe-output processing failures in `githubnext/gh-aw-cao`; the bounded snapshot was truncated to the newest 100 failed runs, so older failures may exist outside this digest.

**Action:** CAO maintainers should triage the two remediation issues below first and confirm whether the remaining recurring clusters already have active owners; accept when the target-authority and activation-artifact clusters each have a confirmed fix owner or existing tracked issue.

Critical findings:
- Public projects scanned: 7
- Failed runs in snapshot: 1,222
- Snapshot scope available to this worker: newest 100 failed runs only (`truncated: true`)
- Cluster counts in bounded evidence: P0 2, P1 6, P2 32
- Existing coverage search could not be completed because GitHub issue reads returned HTTP 502 from the sandbox, so duplicate avoidance is best-effort within this run
- Prioritized remediations: `githubnext/gh-aw-cao` live-mode target authority misconfiguration; `githubnext/gh-aw-workshop` activation artifact upload failures

Prioritized remediation list

1. `githubnext/gh-aw-cao` — repeated pre-activation failures: `Target authority missing: add .github/workflows/cao.json to the target default branch for live mode` across AW Doctor and Dependabot workflows (16 runs in the bounded snapshot, plus 3 runs with a closely related invalid authority declaration message).
2. `githubnext/gh-aw-workshop` — repeated activation failures at `Upload activation artifact` across 5 workflows (5 runs in the bounded snapshot).
3. `githubnext/gh-aw-cao` — repeated safe-output processing failures across SelfCare and Dev Practices / Well-Architected (6 runs in the bounded snapshot); cause is not evidenced beyond the failing step.
4. `github/gh-aw` — repeated agent failures at `Execute Codex CLI` across 8 workflows (8 runs in the bounded snapshot); cause is not evidenced beyond the failing step.
5. `githubnext/gh-aw-cao` — repeated `Generate GitHub App token` failures in AW Optimization / AI Credit Savings (5 runs in the bounded snapshot).

Cluster summary from bounded snapshot

- P0
- `githubnext/gh-aw-workshop` — `Upload activation artifact` across 5 workflows, 5 runs, representative run: https://github.com/githubnext/gh-aw-workshop/actions/runs/33950420537, probable cause: activation artifact publication path or permission failure, confidence: medium.
- `githubnext/gh-aw-cao` — `Process Safe Outputs` across 2 workflows, 6 runs, representative run: https://github.com/githubnext/gh-aw-cao/actions/runs/33950881216, probable cause: safe-output processing failure after agent completion, confidence: low.
- P1
- `githubnext/gh-aw-cao` — target authority missing for live mode across 4 workflows, 16 runs, representative run: https://github.com/githubnext/gh-aw-cao/actions/runs/33951091943, probable cause: target default-branch authority declaration absent for packages requesting live mode, confidence: high.
- `githubnext/gh-aw-cao` — invalid target authority declaration for aw-doctor across 3 workflows, 3 runs, representative run: https://github.com/githubnext/gh-aw-cao/actions/runs/33951036598, probable cause: malformed `target-authority` entry for `aw-doctor`, confidence: high.
- `githubnext/gh-aw-cao` — `Generate GitHub App token` in AW Optimization / AI Credit Savings, 5 runs, representative run: https://github.com/githubnext/gh-aw-cao/actions/runs/33950293180, probable cause: token generation path failure, confidence: low.
- `github/gh-aw` — `Execute Codex CLI` across 8 workflows, 8 runs, representative run: https://github.com/github/gh-aw/actions/runs/33950434728, probable cause: agent invocation failure, confidence: low.
- P2
- 32 additional isolated or insufficient-evidence clusters, mostly conclusion-only failures where the bounded snapshot does not support a cause.

Start with the representative GitHub Actions runs linked in the prioritized remediation list, especially the target-authority and activation-artifact failures. Confirm whether each recurring cluster already has an owner or tracked issue; done means both prioritized clusters have confirmed fix owners or existing tracked issues.
