  "security_notes": "Static-review-only skill: it reads and greps component source but never executes, builds, or runs application code. Flag effects that perform authenticated writes (mutations) without idempotency/cancellation guards — a race condition here can cause duplicate financial or state-changing operations, not just a UI bug — as a HIGH-severity finding requiring immediate escalation, not a style note.",
