**Issue Evaluation** Category: `bug` | Status: **Confirmed** This is a valid race condition bug. The Proxy page uses React loading state for UI feedback but lacks a synchronous mutation guard. Two rapid clicks before React commits the loading state will both call `addProxyAddress`, and add/remove operations can overlap. **Root Cause:** React state (`loading`) is asynchronous — it cannot serve as a synchronous mutex for mutation dispatch. Request IDs only suppress stale UI updates but cannot prevent the duplicate backend write. **Impact:** Duplicate proxy address mutations sent to the backend; potential data inconsistency if add and remove overlap. **Severity:** Medium — affects data integrity under rapid interaction. **Suggested fix:** Introduce a synchronous in-flight guard (e.g., `useRef` Set of pending mutation keys) that is checked and updated synchronously before dispatching the API call. An automated fix proposal can be generated. Reply `/approve` to proceed with PR generation. --- *Automated evaluation by github-manager* -- This is an automated message from the Apache Git Service.
