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

Snapshot 2026-09-06T14:07:57Z covers the last 168 hours across 7 public projects and 561 failed runs. The bounded snapshot is truncated to the newest 100 failed runs, so this digest prioritizes the highest-confidence recurring failures visible in that slice. Within the visible evidence, 9 clusters are recurring P1 failures, 22 are isolated or insufficiently evidenced P2 failures, and no P0 cluster is evidenced.

**Action:** Workflow maintainers should first restore the recurring `Generate GitHub App token` failure in `githubnext/gh-aw-cao` `AW Optimization / AI Credit Savings`; accept when a fresh run completes that step successfully and no new runs with the same signature appear in the next scheduled cycle.

Critical findings:
- `githubnext/gh-aw-cao` dominates the visible failures, including repeated clusters in `AW Optimization / AI Credit Savings`, `Dependabot / Release Trains`, `Dev Practices / Well-Architected`, and `AW Optimization / AI Credit Audit`.
- The two highest-priority untracked recurring clusters with actionable evidence are `Generate GitHub App token` (5 runs) and `Target authority missing: add .github/workflows/cao.json to the target default branch for live mode` (5 runs).
- The snapshot also shows a separate recurring `Process Safe Outputs` failure in `Dev Practices / Well-Architected` (5 runs), but it is lower priority than the two clusters above because the bounded evidence does not yet show the underlying payload fault.
- Existing issue coverage could not be verified from GitHub reads in this run because `gh issue list` failed with host-side errors/timeouts, so duplicate avoidance is incomplete.

Prioritized remediation list

1. `githubnext/gh-aw-cao` — `AW Optimization / AI Credit Savings` — `Generate GitHub App token` — P1 — 5 runs — representative run: https://github.com/githubnext/gh-aw-cao/actions/runs/34036014331
2. `githubnext/gh-aw-cao` — `Dependabot / Release Trains` — `Target authority missing: add .github/workflows/cao.json to the target default branch for live mode` — P1 — 5 runs — representative run: https://github.com/githubnext/gh-aw-cao/actions/runs/34035911897
3. `githubnext/gh-aw-cao` — `Dev Practices / Well-Architected` — `Process Safe Outputs` — P1 — 5 runs — representative run: https://github.com/githubnext/gh-aw-cao/actions/runs/34036249743
4. `githubnext/gh-aw-cao` — `AW Optimization / AI Credit Audit` — `Download agentic workflow logs` — P1 — 4 runs — representative run: https://github.com/githubnext/gh-aw-cao/actions/runs/34024661196
5. `githubnext/gh-aw-cao` — `EU CRA / Supply Chain` — `Check workflow lock file` — P1 — 2 runs — representative run: https://github.com/githubnext/gh-aw-cao/actions/runs/34034545297
6. `githubnext/gh-aw-cao` — `EU CRA / Scope` — `Check workflow lock file` — P1 — 2 runs — representative run: https://github.com/githubnext/gh-aw-cao/actions/runs/34034487100

Coverage and evidence notes

- Public projects scanned: 7 (`github/gh-aw`, `github/gh-aw-actions`, `github/gh-aw-firewall`, `github/gh-aw-mcpg`, `github/gh-aw-threat-detection`, `githubnext/gh-aw-cao`, `githubnext/gh-aw-workshop`)
- Failed runs in snapshot: 561
- Visible failures analyzed from bounded snapshot: newest 100 only (`truncated: true`)
- Cluster counts in visible slice: P0 0, P1 9, P2 22
- Existing coverage status: not fully verified because GitHub issue listing failed with `malformed version`, timeout, and `HTTP 502: resource labeling failed`
- Confidence model: clusters use repository + workflow + strongest available evidence in order `failureMessage`, `failureStep`, `failureJob`, then conclusion-only recurrence.

Start with the representative AW Optimization / AI Credit Savings run and inspect the recurring “Generate GitHub App token” failure, then review the referenced .github/workflows/cao.json configuration and related workflow context. Done means a fresh run completes that step successfully and the same failure signature does not appear in the next scheduled cycle.
