[self-care:open-source-failures] Open-source workflow failure digest for 2026-09-04 snapshot

Snapshot 2026-09-04T20:59:41.884Z over the last 168 hours across 7 public projects found 1101 failed runs clustered into 14 recurring P1 defects and 19 P2/insufficient-evidence defects. No existing `[self-care:open-source-failures]` tracking issues are open for the recurring clusters in this snapshot. The highest-value fixes are repeated live-mode admission failures in `githubnext/gh-aw-cao` where workflows cannot find valid target authority, and repeated token-generation failures in the AI credit optimizer workflow.

**Action:** CAO maintainers should triage the two remediation issues below and accept when the affected workflows complete successfully in new runs without the same signatures.

Critical recurring findings:
- `githubnext/gh-aw-cao`: repeated live-mode pre-activation failures with `Target authority missing...` or invalid `target-authority` declarations across AW Doctor and Dependabot workflows.
- `githubnext/gh-aw-cao`: repeated `Generate GitHub App token` failures in `optimization-ai-credit-optimizer.lock.yml`.
- Additional recurring but lower-priority failures include repeated `Process Safe Outputs` failures in `software-development-practices-github-well-architected.lock.yml`, repeated lock-file check failures, and a short GitHub API admission-limit burst affecting five SelfCare workflows.

Prioritized remediation list

1. `githubnext/gh-aw-cao` — live-mode target authority misconfiguration across AW Doctor and Dependabot workflows (P1, 20 evidenced runs across 4 workflows plus corroborating conclusion-only recurrences).
2. `githubnext/gh-aw-cao` — `Optimization / AI Credit Savings` cannot generate a GitHub App token (P1, 5 enriched runs plus 5 conclusion-only recurrences).

Cluster summary

- P1 clusters: 14
- P2 / insufficient-evidence clusters: 19
- Existing coverage matches found: 0
- Evidence scope: bounded activity snapshot only
- Snapshot truncation: only the newest 100 failed runs were available

Representative recurring clusters:
- `githubnext/gh-aw-cao` / `aw-maintenance-upgrade.lock.yml` / `Target authority missing: add .github/workflows/cao.json to the target default branch for live mode` — 5 runs
- `githubnext/gh-aw-cao` / `aw-maintenance-compiler-security.lock.yml` / same signature — 5 runs
- `githubnext/gh-aw-cao` / `aw-failures-investigator.lock.yml` / same signature — 4 runs
- `githubnext/gh-aw-cao` / `dependabot-release-train-updater.lock.yml` / same signature — 4 runs
- `githubnext/gh-aw-cao` / `optimization-ai-credit-optimizer.lock.yml` / `Generate GitHub App token` — 5 runs
- `githubnext/gh-aw-cao` / `software-development-practices-github-well-architected.lock.yml` / `Process Safe Outputs` — 5 runs
- `githubnext/gh-aw-cao` / multiple SelfCare workflows / `CAO admission blocked: GitHub API limited until 2026-09-04T19:32:43.000Z` — 5 single-workflow recurrences in one burst

Start by inspecting the affected workflows: aw-maintenance-upgrade.lock.yml, aw-maintenance-compiler-security.lock.yml, aw-failures-investigator.lock.yml, dependabot-release-train-updater.lock.yml, optimization-ai-credit-optimizer.lock.yml, and software-development-practices-github-well-architected.lock.yml. Check the cited failed runs and whether .github/workflows/cao.json exists on the target default branch. Done means new runs complete successfully without the reported target-authority or GitHub App token signatures.
