Here’s the complete, end-to-end plan before we touch a single line of code.

────────────────────────────────────────
Goal (the outcome we want)
────────────────────────────────────────
One user click on “Refresh Holdings” does exactly this:

1. UI immediately logs the click and disables the button/spins.  
2. Cache for the currently-selected portfolio is cleared.  
3. Fresh holdings + prices are fetched from Plaid / backend.  
4. Returned portfolio object is up-serted into `PortfolioRepository`, producing a stable new `id`.  
5. That `id` is marked current in `portfolioStore`.  
6. React-Query queries that depend on that portfolio (`portfolioSummary`, `riskScore`, `portfolioAnalysis`, etc.) are cancelled & invalidated so they refetch once with the new content.  
7. When those queries finish, components re-render with fresh data and the button is re-enabled.  
8. Log stream shows:  
   • user-action → cache-clear → Plaid GET → repo add → React-Query refetch – no premature “cache hit” lines.

────────────────────────────────────────
Files & Responsibilities
────────────────────────────────────────
Hook layer (owns ALL side-effects)  
• `hooks/usePlaid.ts` – contains one mutation function `refreshHoldingsMutation`.

UI wrapper layer (pure routing/presentation)  
• `DashboardApp.tsx`  
• `DashboardContainer.tsx`  
Each defines a tiny `handleRefreshHoldings` that only logs the click and calls `refreshHoldings()` from the hook.

Service layer (already exists)  
• `PortfolioManager.refreshHoldings()` – does the backend call.  
• `PortfolioCacheService.clearPortfolio(id)` – clears cache.

Repository layer  
• `PortfolioRepository.add(portfolio)` / `setCurrent(id)` – upsert & select.

────────────────────────────────────────
Implementation Steps
────────────────────────────────────────
1. In `usePlaid.ts`
   a. Import `useQueryClient`, `usePortfolioStore`, `PortfolioRepository`.  
   b. Create `refreshHoldingsMutation` with this exact flow:  
      i.  Read `prevId = usePortfolioStore.getState().currentPortfolioId`.  
      ii. `cache.clearPortfolio(prevId)` (if any).  
      iii.`const result = await manager.refreshHoldings()`; validate.  
      iv. `const newId = PortfolioRepository.add(result.portfolio);`  
      v.  `PortfolioRepository.setCurrent(newId);`  
      vi. Cancel & invalidate query keys that include `newId`.  
   c. Expose only `refreshHoldings` (wrapper to `mutateAsync`) and optionally `isRefreshing`.

2. In **both** dashboard wrappers:  
   ```tsx
   const { refreshHoldings } = usePlaid();
   const handleRefreshHoldings = () => {
     frontendLogger.user.action('refreshHoldings', 'DashboardContainer');
     refreshHoldings();
   };
   ```  
   No other logic. Remove any leftover async stubs, `setViewLoading`, or manual `refetch`.

3. Remove all `setTimeout` debug stubs and any direct `portfolioSummaryHook.refetch()` related to refresh.

4. Testing / verification  
   • Run the app, click Refresh.  
   • Confirm log order matches the desired sequence.  
   • Ensure no stale cache-hit lines appear before the Plaid GET.  
   • Make sure only one mutation runs even if the button is clicked rapidly (React-Query handles de-dupe).

5. (Optional) expose `isRefreshingHoldings` from the hook and disable the button in the UI; that’s purely cosmetic.

────────────────────────────────────────
What will NOT change
────────────────────────────────────────
• No new constants or props unless strictly necessary.  
• No architecture changes outside the hook.  
• No alterations to unrelated files.

If you approve this exact plan, I’ll implement steps 1-2 in one commit, then we’ll run the UI and inspect the logs together to confirm it behaves exactly as specified.

ok so does this make sense - /**
