 ## Known Issues
 
-### 🔴 HIGH: secrets-store.ts Performance
+### ✅ MEDIUM: secrets-store.ts Performance (mitigated)
 **File:** `canvas/src/stores/secrets-store.ts`
-**Issue:** `getGrouped()` selector creates new objects every call (Object.fromEntries + arrays). Not memoized.
-**Impact:** Causes unnecessary re-renders on frequent selector access.
-**Fix needed:** Memoize the selector or use a proper Zustand selector pattern.
+**Issue:** `getGrouped()` selector creates new objects every call. Not memoized.
+**Impact:** Mitigated — `SecretsTab.tsx` wraps the call in `useMemo`, so no active re-render issues in the single consumer. The store-level fix (memoizing `getGrouped` itself) is optional but low priority now.
 
 ### 🟡 MEDIUM: Pre-commit Hook Verification
 **Issue:** Pre-commit hook checks 'use client' on hook-using components but unclear if it actually fails on violations.
