+# Agent Work Orders: SSE + Zustand State Management Standards
+
+## Purpose
+
+This document defines the **complete architecture, patterns, and standards** for implementing Zustand state management with Server-Sent Events (SSE) in the Agent Work Orders feature. It serves as the authoritative reference for:
+
+- State management boundaries (what goes in Zustand vs TanStack Query vs local useState)
+- SSE integration patterns and connection management
+- Zustand slice organization and naming conventions
+- Anti-patterns to avoid
+- Migration strategy and implementation plan
+
+**This is a pilot feature** - patterns established here will be applied to other features (Knowledge Base, Projects, Settings).
+
+---
+
+## Current State Analysis
+
+### Component Structure
+- **Total Lines:** ~4,400 lines
+- **Components:** 10 (RepositoryCard, WorkOrderTable, modals, etc.)
+- **Views:** 2 (AgentWorkOrdersView, AgentWorkOrderDetailView)
+- **Hooks:** 4 (useAgentWorkOrderQueries, useRepositoryQueries, useWorkOrderLogs, useLogStats)
+- **Services:** 2 (agentWorkOrdersService, repositoryService)
+
+### Current State Management (42 useState calls)
+
+**AgentWorkOrdersView (8 state variables):**
+```typescript
+const [layoutMode, setLayoutMode] = useState<LayoutMode>(getInitialLayoutMode);
+const [sidebarExpanded, setSidebarExpanded] = useState(true);
+const [showAddRepoModal, setShowAddRepoModal] = useState(false);
+const [showEditRepoModal, setShowEditRepoModal] = useState(false);
+const [editingRepository, setEditingRepository] = useState<ConfiguredRepository | null>(null);
+const [showNewWorkOrderModal, setShowNewWorkOrderModal] = useState(false);
+const [searchQuery, setSearchQuery] = useState("");
+const selectedRepositoryId = searchParams.get("repo") || undefined;
+```
+
+**Problems:**
+- Manual localStorage management (layoutMode)
+- Prop drilling for modal controls
+- No persistence for searchQuery or sidebarExpanded
+- Scattered state across multiple useState calls
+
+---
+
+## SSE Architecture (Already Implemented!)
+
+### Backend SSE Streams
+
+**1. Log Stream (✅ Complete)**
+```
+GET /api/agent-work-orders/{id}/logs/stream
+```
+
+**What it provides:**
+- Real-time structured logs from workflow execution
+- Event types: `workflow_started`, `step_started`, `step_completed`, `workflow_completed`, `workflow_failed`
+- Rich metadata in each log: `step`, `step_number`, `total_steps`, `progress`, `progress_pct`, `elapsed_seconds`
+- Filters: level, step, since timestamp
+- Heartbeat every 15 seconds
+
+**Frontend Integration:**
+- ✅ `useWorkOrderLogs` hook - EventSource connection with auto-reconnect
+- ✅ `useLogStats` hook - Parses logs to extract progress metrics
+- ✅ `RealTimeStats` component - Now uses real SSE data (was mock)
+- ✅ `ExecutionLogs` component - Now displays real logs (was mock)
+
+**Key Insight:** SSE logs contain ALL progress information including:
+- Current step and progress percentage
+- Elapsed time
+- Step completion status
+- Git stats (from log events)
+- Workflow lifecycle events
+
+---
+
+### Current Polling (Should Be Replaced)
+
+**useWorkOrders() - Polls every 3s:**
+```typescript
+refetchInterval: (query) => {
+  const hasActiveWorkOrders = data?.some((wo) => wo.status === "running" || wo.status === "pending");
+  return hasActiveWorkOrders ? 3000 : false;
+}
+```
+
+**useWorkOrder(id) - Polls every 3s:**
+```typescript
+refetchInterval: (query) => {
+  if (data?.status === "running" || data?.status === "pending") {
+    return 3000;
+  }
+  return false;
+}
+```
+
+**useStepHistory(id) - Polls every 3s:**
+```typescript
+refetchInterval: (query) => {
+  const lastStep = history?.steps[history.steps.length - 1];
+  if (lastStep?.step === "create-pr" && lastStep?.success) {
+    return false;
+  }
+  return 3000;
+}
+```
+
+**Network Impact:**
+- 3 active work orders = ~140 HTTP requests/minute
+- With ETags: ~50-100KB/minute bandwidth
+- Up to 3 second delay for updates
+
+---
+
+## Zustand State Management Standards
+
+### Core Principles
+
+**1. State Categorization:**
+- **UI Preferences** → Zustand (persisted)
+- **Modal State** → Zustand (NOT persisted)
+- **Filter State** → Zustand (persisted)
+- **SSE Connections** → Zustand (NOT persisted)
+- **Server Data** → TanStack Query (cached)
+- **Form State** → Zustand slices OR local useState (depends on complexity)
+- **Ephemeral UI** → Local useState (component-specific)
+
+**2. Selective Subscriptions:**
+```typescript
+// ✅ GOOD - Only re-renders when layoutMode changes
+const layoutMode = useAgentWorkOrdersStore((s) => s.layoutMode);
+const setLayoutMode = useAgentWorkOrdersStore((s) => s.setLayoutMode);
+
+// ❌ BAD - Re-renders on ANY state change
+const { layoutMode, searchQuery, selectedRepositoryId } = useAgentWorkOrdersStore();
+```
+
+**3. Server State Boundary:**
+```typescript
+// ✅ GOOD - TanStack Query for initial load, mutations, caching
+const { data: repositories } = useRepositories();
+
+// ✅ GOOD - Zustand for real-time SSE updates
+const liveWorkOrder = useAgentWorkOrdersStore((s) => s.liveWorkOrders[id]);
+
+// ✅ GOOD - Combine them
+const workOrder = liveWorkOrder || cachedWorkOrder; // SSE overrides cache
+
+// ❌ BAD - Duplicating server state in Zustand
+const repositories = useAgentWorkOrdersStore((s) => s.repositories); // DON'T DO THIS
+```
+
+**4. Slice Organization:**
+- One slice per concern (modals, UI prefs, filters, SSE)
+- Each slice is independently testable
+- Slices can reference each other via get()
+- Use TypeScript for all slice types
+
+---
+
+## Zustand Store Structure

+ */
+export const useAgentWorkOrdersStore = create<AgentWorkOrdersStore>()(
+  devtools(

+
+### UI Preferences Slice
+
+```typescript

+    }),
+});
+```
+
+**Replaces:**
+- Manual localStorage get/set (~20 lines eliminated)
+- getInitialLayoutMode, saveLayoutMode functions
+- useState for layoutMode and sidebarExpanded
+

+
+### Modals Slice (With Optional Form State)
+
+```typescript
+// src/features/agent-work-orders/state/slices/modalsSlice.ts
+
+import { StateCreator } from 'zustand';
+import type { ConfiguredRepository } from '../../types/repository';
+import type { WorkflowStep } from '../../types';

+/**

+ *
+ * Manages modal visibility and context (which repository is being edited, etc.).
+ * Enables opening modals from anywhere without prop drilling.
+ *
+ * Persisted: NO (modals should not persist across page reloads)
+ *
+ * Note: Form state (repositoryUrl, selectedSteps, etc.) can be added to this slice
+ * if centralized validation/submission logic is desired. For simple forms that
+ * reset on close, local useState in the modal component is cleaner.
+ */
+export const createModalsSlice: StateCreator<
+  ModalsSlice,
+  [],
+  [],
+  ModalsSlice
+> = (set) => ({
+  // Initial state
+  showAddRepoModal: false,

+      editingRepository: null,
+      preselectedRepositoryId: undefined,
+    }),
+});
+```
+
+**Replaces:**
+- Multiple useState calls for modal visibility (~5 states)
+- handleEditRepository, handleCreateWorkOrder helper functions
+- Prop drilling for modal open/close callbacks

+### Filters Slice
+
+```typescript
+// src/features/agent-work-orders/state/slices/filtersSlice.ts
+

+  },
+
+  clearFilters: () =>
+    set({
+      searchQuery: '',

+```
+
+**Replaces:**
+- useState for searchQuery
+- Manual selectRepository function

+  },
+});
+```

+
+## Component Integration Patterns
+
+### Pattern 1: RealTimeStats (SSE + Zustand)
+
+**Current (just fixed):**
+```typescript
+export function RealTimeStats({ workOrderId }: RealTimeStatsProps) {
+  const { logs } = useWorkOrderLogs({ workOrderId }); // Direct SSE hook
+  const stats = useLogStats(logs); // Parse logs
+
+  // Display stats.currentStep, stats.progressPct, etc.
+}
+```
+
+**With Zustand SSE Slice:**
+```typescript
+export function RealTimeStats({ workOrderId }: RealTimeStatsProps) {
+  // Connect to SSE (Zustand manages connection)
+  const connectToLogs = useAgentWorkOrdersStore((s) => s.connectToLogs);
+  const disconnectFromLogs = useAgentWorkOrdersStore((s) => s.disconnectFromLogs);
+
+  useEffect(() => {
+    connectToLogs(workOrderId);
+    return () => disconnectFromLogs(workOrderId);
+  }, [workOrderId]);
+
+  // Subscribe to parsed progress (Zustand parses logs automatically)
+  const progress = useAgentWorkOrdersStore((s) => s.liveProgress[workOrderId]);
+
+  // Display progress.currentStep, progress.progressPct, etc.
+  // No need for useLogStats - Zustand already parsed it!
+}
+```
+
+**Benefits:**
+- Zustand handles connection lifecycle
+- Multiple components can display progress without multiple connections
+- Automatic cleanup when all subscribers unmount
+
+---
+
+### Pattern 2: WorkOrderRow (Hybrid TanStack + Zustand)
+
+**Current:**
+```typescript
+const { data: workOrder } = useWorkOrder(id); // Polls every 3s
+```
+
+**With Zustand:**
+```typescript
+// Initial load from TanStack Query (cached, no polling)
+const { data: cachedWorkOrder } = useWorkOrder(id, {
+  refetchInterval: false, // NO MORE POLLING!
+});
+
+// Live updates from SSE (via Zustand)
+const liveProgress = useAgentWorkOrdersStore((s) => s.liveProgress[id]);
+
+// Merge: SSE overrides cached data
+const workOrder = {
+  ...cachedWorkOrder,
+  ...liveProgress, // status, git_commit_count, etc. from SSE
+};
+```
+
+**Benefits:**
+- No polling (0 HTTP requests while connected)
+- Instant updates from SSE
+- TanStack Query still handles initial load, mutations, caching
+
+---
+
+### Pattern 3: Modal Management (No Prop Drilling)
+
+**Current:**
+```typescript
+// AgentWorkOrdersView
+const [showEditRepoModal, setShowEditRepoModal] = useState(false);
+const [editingRepository, setEditingRepository] = useState<ConfiguredRepository | null>(null);
+
+const handleEditRepository = (repository: ConfiguredRepository) => {
+  setEditingRepository(repository);
+  setShowEditRepoModal(true);
+};
+
+// Pass down to child
+<RepositoryCard onEdit={() => handleEditRepository(repository)} />
+```
+
+**With Zustand:**
+```typescript
+// RepositoryCard (no props needed)
+const openEditRepoModal = useAgentWorkOrdersStore((s) => s.openEditRepoModal);
+<Button onClick={() => openEditRepoModal(repository)}>Edit</Button>
+
+// AgentWorkOrdersView (just renders modal)
+const showEditRepoModal = useAgentWorkOrdersStore((s) => s.showEditRepoModal);
+const closeEditRepoModal = useAgentWorkOrdersStore((s) => s.closeEditRepoModal);
+const editingRepository = useAgentWorkOrdersStore((s) => s.editingRepository);
+
+<EditRepositoryModal
+  open={showEditRepoModal}
+  onOpenChange={closeEditRepoModal}
+  repository={editingRepository}
+/>
+```
+
+**Benefits:**
+- Can open modal from anywhere (breadcrumb, keyboard shortcut, etc.)
+- No callback props
+- Cleaner component tree
+
+---
+
+## Anti-Patterns (DO NOT DO)
+
+### ❌ Anti-Pattern 1: Subscribing to Full Store
+```typescript
+// BAD - Component re-renders on ANY state change
+const store = useAgentWorkOrdersStore();
+const { layoutMode, searchQuery, selectedRepositoryId } = store;
+```
+
+**Why bad:**
+- Component re-renders even if only unrelated state changes
+- Defeats the purpose of Zustand's selective subscriptions
+
+**Fix:**
+```typescript
+// GOOD - Only re-renders when layoutMode changes
+const layoutMode = useAgentWorkOrdersStore((s) => s.layoutMode);
+```
+
+---
+
+### ❌ Anti-Pattern 2: Duplicating Server State
+```typescript
+// BAD - Storing server data in Zustand
+type BadSlice = {
+  repositories: ConfiguredRepository[];
+  workOrders: AgentWorkOrder[];
+  isLoadingRepos: boolean;
+  fetchRepositories: () => Promise<void>;
+};
+```
+
+**Why bad:**
+- Reimplements TanStack Query (caching, invalidation, optimistic updates)
+- Loses Query features (background refetch, deduplication, etc.)
+- Increases complexity
+
+**Fix:**
+```typescript
+// GOOD - TanStack Query for server data
+const { data: repositories } = useRepositories();
+
+// GOOD - Zustand ONLY for SSE overlays
+const liveUpdates = useAgentWorkOrdersStore((s) => s.liveWorkOrders);
+```
+
+---
+
+### ❌ Anti-Pattern 3: Putting Everything in Global State
+```typescript
+// BAD - Form state in Zustand when it shouldn't be
+type BadSlice = {
+  addRepoForm: {
+    repositoryUrl: string;
+    error: string;
+    isSubmitting: boolean;
+  };
+  expandedWorkOrderRows: Set<string>; // Per-row state in global store!
+};
+```
+
+**Why bad:**
+- Clutters global state with component-local concerns
+- Forms that reset on close don't need global state
+- Row expansion is per-instance, not global
+
+**Fix:**
+```typescript
+// GOOD - Local useState for simple forms
+export function AddRepositoryModal() {
+  const [repositoryUrl, setRepositoryUrl] = useState("");
+  const [error, setError] = useState("");
+  // Resets on modal close - perfect for local state
+}
+
+// GOOD - Local useState for per-component UI
+export function WorkOrderRow() {
+  const [isExpanded, setIsExpanded] = useState(false);
+  // Each row has its own expansion state
+}
+```
+
+---
+
+### ❌ Anti-Pattern 4: Using getState() in Render Logic
+```typescript
+// BAD - Doesn't subscribe to changes
+function MyComponent() {
+  const layoutMode = useAgentWorkOrdersStore.getState().layoutMode;
+  // Component won't re-render when layoutMode changes!
+}
+```
+
+**Why bad:**
+- getState() doesn't create a subscription
+- Component won't re-render on state changes
+- Silent bugs
+
+**Fix:**
+```typescript
+// GOOD - Proper subscription
+const layoutMode = useAgentWorkOrdersStore((s) => s.layoutMode);
+```
+
+---
+
+### ❌ Anti-Pattern 5: Not Cleaning Up SSE Connections
+```typescript
+// BAD - Connection leaks
+useEffect(() => {
+  connectToLogs(workOrderId);
+  // Missing cleanup!
+}, [workOrderId]);
+```
+
+**Why bad:**
+- EventSource connections stay open forever
+- Memory leaks
+- Browser connection limit (6 per domain)
+
+**Fix:**
+```typescript
+// GOOD - Cleanup on unmount
+useEffect(() => {
+  connectToLogs(workOrderId);
+  return () => disconnectFromLogs(workOrderId);
+}, [workOrderId]);
+```
+

+
+## Implementation Checklist
+
+### Phase 1: Zustand Foundation (Frontend Only)
+- [ ] Create `agentWorkOrdersStore.ts` with slice pattern
+- [ ] Create `uiPreferencesSlice.ts` (layoutMode, sidebarExpanded)
+- [ ] Create `modalsSlice.ts` (modal visibility, editing context)
+- [ ] Create `filtersSlice.ts` (searchQuery, selectedRepositoryId)
+- [ ] Add persist middleware (only UI prefs and filters)
+- [ ] Add devtools middleware
+- [ ] Write store tests
+
+**Expected Changes:**
+- +350 lines (store + slices)
+- -50 lines (remove localStorage boilerplate, helper functions)
+- Net: +300 lines
+
+---
+
+### Phase 2: Migrate AgentWorkOrdersView (Frontend Only)
+- [ ] Replace useState with Zustand selectors
+- [ ] Remove localStorage helper functions (getInitialLayoutMode, saveLayoutMode)
+- [ ] Remove modal helper functions (handleEditRepository, etc.)
+- [ ] Update modal open/close to use Zustand actions

+- [ ] Test thoroughly (layouts, modals, navigation)
+
+**Expected Changes:**
+- AgentWorkOrdersView: -40 lines (400 → 360)
+- Eliminate prop drilling for modal callbacks
+
+---
+
+### Phase 3: SSE Integration (Frontend Only)
+- [ ] Already done! RealTimeStats now uses real SSE data
+- [ ] Already done! ExecutionLogs now displays real logs
+- [ ] Verify SSE connection works in browser
+- [ ] Check Network tab for `/logs/stream` connection
+- [ ] Verify logs appear in real-time
+
+**Expected Changes:**
+- None needed - just fixed mock data usage
+
+---
+
+### Phase 4: Remove Polling (Frontend Only)
+- [ ] Create `sseSlice.ts` for connection management

+- [ ] Test that status/progress updates appear instantly
+
+**Expected Changes:**
+- +150 lines (SSE slice)
+- -40 lines (remove polling logic)
+- Net: +110 lines
+
+---

+
+## Testing Standards
+
+### Store Testing
+```typescript
+// agentWorkOrdersStore.test.ts
+import { useAgentWorkOrdersStore } from './agentWorkOrdersStore';
+

+```
+
+---
+
+## Performance Expectations
+
+### Current (With Polling)
+- **HTTP Requests:** 140/min (3 active work orders)
+- **Bandwidth:** 50-100KB/min (with ETags)
+- **Latency:** Up to 3 second delay for updates
+- **Client CPU:** Moderate (constant polling, re-renders)
+
+### After (With SSE + Zustand)
+- **HTTP Requests:** ~14/min (only for mutations and initial loads)
+- **SSE Connections:** 1-5 persistent connections
+- **Bandwidth:** 5-10KB/min (events only, no 304 overhead)
+- **Latency:** <100ms (instant SSE delivery)
+- **Client CPU:** Lower (event-driven, selective re-renders)
+
+**Savings: 90% bandwidth reduction, 95% request reduction, instant updates**
+
+---
+
+## Migration Risk Assessment
+
+### Low Risk
+- ✅ UI Preferences slice (localStorage → Zustand persist)
+- ✅ Modals slice (no external dependencies)
+- ✅ SSE logs integration (already built, just use it)
+
+### Medium Risk
+- ⚠️ URL sync with Zustand (needs careful testing)
+- ⚠️ SSE connection management (need proper cleanup)
+- ⚠️ Selective subscriptions (team must learn pattern)
+
+### High Risk (Don't Do)
+- ❌ Replacing TanStack Query with Zustand (don't do this!)
+- ❌ Global state for all forms (overkill)
+- ❌ Putting row expansion in global state (terrible idea)
+
+---
+
+## Decision Matrix: What Goes Where?
+
+| State Type | Current | Should Be | Reason |
+|------------|---------|-----------|--------|
+| layoutMode | useState + localStorage | Zustand (persisted) | Automatic persistence, global access |
+| sidebarExpanded | useState | Zustand (persisted) | Should persist across reloads |
+| showAddRepoModal | useState | Zustand (not persisted) | Enable opening from anywhere |
+| editingRepository | useState | Zustand (not persisted) | Context for edit modal |
+| searchQuery | useState | Zustand (persisted) | Persist search across navigation |
+| selectedRepositoryId | URL params | Zustand + URL sync (persisted) | Dual source: Zustand cache + URL truth |
+| repositories (server) | TanStack Query | TanStack Query | Perfect for server state |
+| workOrders (server) | TanStack Query | TanStack Query + SSE overlay | Initial load (Query), updates (SSE) |
+| repositoryUrl (form) | useState in modal | useState in modal | Simple, resets on close |
+| selectedSteps (form) | useState in modal | useState in modal | Simple, resets on close |
+| isExpanded (row) | useState per row | useState per row | Component-specific |
+| SSE connections | useWorkOrderLogs hook | Zustand SSE slice | Centralized management |
+| logs (from SSE) | useWorkOrderLogs hook | Zustand SSE slice | Share across components |
+| progress (parsed logs) | useLogStats hook | Zustand SSE slice | Auto-parse on event |
+
+---
+
+## Code Examples
+
+### Before: AgentWorkOrdersView (Current)
+```typescript
+export function AgentWorkOrdersView() {
+  // 8 separate useState calls
+  const [layoutMode, setLayoutMode] = useState<LayoutMode>(getInitialLayoutMode);
+  const [sidebarExpanded, setSidebarExpanded] = useState(true);
+  const [showAddRepoModal, setShowAddRepoModal] = useState(false);
+  const [showEditRepoModal, setShowEditRepoModal] = useState(false);
+  const [editingRepository, setEditingRepository] = useState<ConfiguredRepository | null>(null);
+  const [showNewWorkOrderModal, setShowNewWorkOrderModal] = useState(false);
+  const [searchQuery, setSearchQuery] = useState("");
+  const selectedRepositoryId = searchParams.get("repo") || undefined;
+
+  // Helper functions (20+ lines)
+  const updateLayoutMode = (mode: LayoutMode) => {
+    setLayoutMode(mode);
+    saveLayoutMode(mode); // Manual localStorage
+  };
+
+  const handleEditRepository = (repository: ConfiguredRepository) => {
+    setEditingRepository(repository);
+    setShowEditRepoModal(true);
+  };
+
+  // Server data (polls every 3s)
+  const { data: repositories = [] } = useRepositories();
+  const { data: workOrders = [] } = useWorkOrders(); // Polling!
+
+  // ... 400 lines total
+}
+```
+
+---
+
+### After: AgentWorkOrdersView (With Zustand)
+```typescript
+export function AgentWorkOrdersView() {
+  const [searchParams, setSearchParams] = useSearchParams();
+
+  // Zustand UI Preferences
+  const layoutMode = useAgentWorkOrdersStore((s) => s.layoutMode);
+  const sidebarExpanded = useAgentWorkOrdersStore((s) => s.sidebarExpanded);
+  const setLayoutMode = useAgentWorkOrdersStore((s) => s.setLayoutMode);
+  const toggleSidebar = useAgentWorkOrdersStore((s) => s.toggleSidebar);
+
+  // Zustand Modals
+  const showAddRepoModal = useAgentWorkOrdersStore((s) => s.showAddRepoModal);
+  const showEditRepoModal = useAgentWorkOrdersStore((s) => s.showEditRepoModal);
+  const showCreateWorkOrderModal = useAgentWorkOrdersStore((s) => s.showCreateWorkOrderModal);
+  const editingRepository = useAgentWorkOrdersStore((s) => s.editingRepository);
+  const openAddRepoModal = useAgentWorkOrdersStore((s) => s.openAddRepoModal);
+  const openEditRepoModal = useAgentWorkOrdersStore((s) => s.openEditRepoModal);
+  const closeEditRepoModal = useAgentWorkOrdersStore((s) => s.closeEditRepoModal);
+  const openCreateWorkOrderModal = useAgentWorkOrdersStore((s) => s.openCreateWorkOrderModal);
+  const closeCreateWorkOrderModal = useAgentWorkOrdersStore((s) => s.closeCreateWorkOrderModal);
+
+  // Zustand Filters
+  const searchQuery = useAgentWorkOrdersStore((s) => s.searchQuery);
+  const selectedRepositoryId = useAgentWorkOrdersStore((s) => s.selectedRepositoryId);
+  const setSearchQuery = useAgentWorkOrdersStore((s) => s.setSearchQuery);
+  const selectRepository = useAgentWorkOrdersStore((s) => s.selectRepository);
+
+  // Sync Zustand with URL params (bidirectional)
+  useEffect(() => {
+    const urlRepoId = searchParams.get("repo") || undefined;
+    if (urlRepoId !== selectedRepositoryId) {
+      selectRepository(urlRepoId, setSearchParams);
+    }
+  }, [searchParams]);
+
+  // Server data (TanStack Query - NO POLLING after Phase 4)
+  const { data: repositories = [] } = useRepositories();
+  const { data: cachedWorkOrders = [] } = useWorkOrders({ refetchInterval: false });
+
+  // Live updates from SSE (Phase 4)
+  const liveWorkOrders = useAgentWorkOrdersStore((s) => s.liveWorkOrders);
+  const workOrders = cachedWorkOrders.map((wo) => ({
+    ...wo,
+    ...(liveWorkOrders[wo.agent_work_order_id] || {}), // SSE overrides
+  }));
+
+  // ... ~360 lines total (-40 lines)
+}
+```
+
+**Changes:**
+- ✅ No manual localStorage (automatic via persist)
+- ✅ No helper functions (actions are in store)
+- ✅ Can open modals from anywhere
+- ✅ No polling (SSE provides updates)
+- ❌ More verbose selectors (but clearer intent)

+**Data Flow:**
+1. **Initial Load:** TanStack Query → REST API → Cache
+2. **Real-Time Updates:** SSE Stream → Zustand SSE Slice → Components
+3. **User Actions:** Component → Zustand Action → TanStack Query Mutation → REST API
+4. **UI State:** Component → Zustand Selector → Render
+
+---
+
+## Summary
+
+### Use Zustand For:
+1. ✅ **UI Preferences** (layoutMode, sidebarExpanded) - Persisted
+2. ✅ **Modal State** (visibility, editing context) - NOT persisted
+3. ✅ **Filter State** (search, selected repo) - Persisted
+4. ✅ **SSE Management** (connections, live data parsing) - NOT persisted
+
+### Use Zustand Slices For:
+1. ✅ **Modals** - Clean separation, no prop drilling
+2. ✅ **UI Preferences** - Persistence with minimal code
+3. ✅ **SSE** - Connection lifecycle management
+4. ⚠️ **Forms** - Only if complex validation or "save draft" needed
+5. ❌ **Ephemeral UI** - Keep local useState for row expansion, etc.
+
+### Keep TanStack Query For:
+1. ✅ **Server Data** - Initial loads, caching, mutations
+2. ✅ **Optimistic Updates** - TanStack Query handles this perfectly
+3. ✅ **Request Deduplication** - Built-in
+4. ✅ **Background Refetch** - For completed work orders (no SSE needed)
+
+### Keep Local useState For:
+1. ✅ **Simple Forms** - Reset on close, no sharing needed
+2. ✅ **Ephemeral UI** - Row expansion, animation triggers
+3. ✅ **Component-Specific** - showLogs toggle in RealTimeStats

+- **Bandwidth:** 50-100KB/min → 5-10KB/min (-90%)
+- **Update Latency:** 3 seconds → <100ms (-97%)
+- **Client Re-renders:** Reduced (selective subscriptions)
+
+### Developer Experience
+- ✅ No manual localStorage management
+- ✅ No prop drilling for modals
+- ✅ Truly real-time updates (SSE)
+- ✅ Better debugging (Zustand DevTools)
+- ⚠️ Slightly more verbose (selective subscriptions)
+- ⚠️ Learning curve (Zustand patterns, SSE lifecycle)
+
+**Verdict: Net positive - real-time architecture is worth the 11% code increase**
+
+---
+
+## Next Steps
+
+**DO NOT IMPLEMENT YET - This document is the reference for creating a PRP.**
+
+When creating the PRP:
+1. Reference this document for architecture decisions
+2. Follow the 5-phase implementation plan
+3. Include all anti-patterns as validation gates
+4. Add comprehensive test requirements
+5. Document Zustand + SSE patterns for other features to follow
+
+This is a **pilot feature** - success here validates the pattern for Knowledge Base, Projects, and Settings.
