[self-care:open-source-failures] Open-source failures digest: repeated target-authority and token-generation breakages

The 2026-09-04T23:59:01.279Z snapshot captured 736 failed runs across 7 public projects in the last 168 hours; the newest 100 failed runs were available, so findings are bounded and likely undercount older recurrence. The highest-priority untracked defects are repeated target-authority pre-activation failures blocking four `githubnext/gh-aw-cao` workflows and repeated GitHub App token generation failures blocking the AI credit optimizer.

**Action:** `githubnext/gh-aw-cao` maintainers should triage the two remediation issues below first; accept when the cited workflows complete successfully on new runs without the same signatures.

- Public projects scanned: 7
- Failed runs in window: 736
- Snapshot bound: newest 100 failed runs only (`truncated: true`)
- Clusters found in bounded evidence: 16
- Severity mix: P0 0, P1 16, P2 0 in tracked output set from repeated signatures; lower-confidence singletons were excluded from remediation
- Existing open coverage in `githubnext/gh-aw-cao`: 0 matching `[self-care:open-source-failures]` issues
- Prioritized remediation list:
1. Fix missing or invalid target-authority declarations affecting AW Doctor and Dependabot release-train workflows.
2. Restore GitHub App token generation for `optimization-ai-credit-optimizer.lock.yml`.

Critical findings

1. **Shared control-plane authority defect**
Repository: `githubnext/gh-aw-cao`
Workflows: `.github/workflows/aw-failures-investigator.lock.yml`, `.github/workflows/aw-maintenance-compiler-security.lock.yml`, `.github/workflows/aw-maintenance-upgrade.lock.yml`, `.github/workflows/dependabot-release-train-updater.lock.yml`
Severity: P1
Runs in bounded snapshot: 23 total corroborating runs, including 20 with explicit target-authority messages.
Representative run: https://github.com/githubnext/gh-aw-cao/actions/runs/33930893795
Evidence-supported cause: live-mode pre-activation rejects execution because target authority is missing or does not declare the required package authority fields.

2. **Optimizer credential bootstrap defect**
Repository: `githubnext/gh-aw-cao`
Workflow: `.github/workflows/optimization-ai-credit-optimizer.lock.yml`
Severity: P1
Runs in bounded snapshot: 5
Representative run: https://github.com/githubnext/gh-aw-cao/actions/runs/33929404817
Evidence-supported cause: the agent job repeatedly fails at `Generate GitHub App token`; the bounded evidence does not show why token generation failed.

3. **Additional repeated but lower-priority bounded clusters**
Repeated conclusion-only failures also appear in `github/gh-aw`, `github/gh-aw-firewall`, `github/gh-aw-mcpg`, and `githubnext/gh-aw-workshop`, but the newest-100-run snapshot does not provide enough enriched evidence to support focused remediation issues without inventing cause.

Inspect the four cited workflow files and the representative runs for target-authority failures, then inspect .github/workflows/optimization-ai-credit-optimizer.lock.yml and its token-generation run. Start by comparing the workflow declarations with the pre-activation and token-generation errors. Done means new runs complete successfully without the reported failure signatures.
