[uk-ai-resilience] Untracked code-scanning alert #564 in README.md (Tier B)

### Tier: B — Open With Conditions

**Finding:** CodeQL alert `workflow-security-finding-1` (#564, warning severity) in `README.md`, currently open with **no existing tracking issue** — the only untracked finding identified in this recent-changes review.

### Risk-scoring breakdown
| Dimension | Rating |
|---|---|
| Exposure amplification | Low |
| Patchability | High |
| Detectability | Low (no issue currently tracks it, so it isn't visible in remediation queues) |
| Operational fragility | Low |
| Ownership confidence | Low — no `CODEOWNERS` file assigns an owner |

### Remediation action
Review the flagged content in `README.md` against alert #564, confirm whether it is a false positive or needs edits, and dismiss or fix accordingly. Assign an owner for follow-up (repo currently has no `CODEOWNERS` file, which is a related governance gap).

**SLA urgency:** medium (14 days)

Start with the CodeQL alert #564 and the flagged content in README.md. Compare the alert details with the current README, determine whether it is a false positive or requires an edit, and check the repository's ownership setup, including the absence of CODEOWNERS. Done means the alert is fixed or dismissed with the follow-up owner recorded.
