# Test Report: Minimum Nodes Per Plan Setting
**Date:** 2026-03-04
**Tester:** Principal QA Engineer
**Test Type:** Code Review + Manual Testing Protocol
**Severity:** CRITICAL ISSUE FOUND

---

## Executive Summary

**CRITICAL BUG DETECTED: Settings sync not triggered on save**

The feature implementation is 95% complete with excellent code quality, but contains a **critical integration bug** that prevents the minimum nodes validation from working when users change settings in the UI. Settings sync only occurs on WebSocket connection, NOT when users click "Save Changes" in the Settings modal.

**Status:** FAIL - Feature non-functional due to missing event handler

---

## Environment
- UI URL: http://localhost:3031
- WebSocket: ws://localhost:3030
- Servers: RUNNING (verified via lsof)
- Test Method: Code review (Playwright MCP unavailable)

---

## Code Review Results

### Files Analyzed

#### 1. UI Settings Store (/packages/ui/src/stores/settings-store.ts)
**Status:** PASS
**Quality:** Excellent

Strengths:
- Clean Zustand store with localStorage persistence
- Proper value clamping (1-20 range)
- Exported constants for range validation
- Partialize prevents storing unnecessary state

Code snippet (lines 30-34):
```typescript
setMinNodesPerPlan: (value: number) => {
  // Clamp value to valid range
  const clampedValue = Math.min(Math.max(value, MIN_NODES_MIN), MIN_NODES_MAX);
  set({ minNodesPerPlan: clampedValue });
},
```

#### 2. Settings Modal (/packages/ui/src/components/Modals/SettingsModal.tsx)
**Status:** PASS (UI implementation)
**Critical Issue:** Missing syncSettings call

Strengths:
- Excellent UX with local state management for cancel functionality
- Proper animations (Framer Motion)
- Increment/decrement with boundary checks
- Clean UI matching app design system

**BUG LOCATION (line 29-32):**
```typescript
const handleSave = () => {
  setMinNodesPerPlan(localMinNodes);  // Updates Zustand store
  onClose();                          // Closes modal
  // MISSING: syncSettings() call to notify server!
};
```

#### 3. Header Component (/packages/ui/src/components/Layout/Header.tsx)
**Status:** PASS
**Quality:** Good

- Settings button properly placed (line 160-168)
- Modal state management correct
- Gear icon visible and accessible

#### 4. Server Settings Store (/packages/mcp-server/src/store/settings-store.ts)
**Status:** PASS
**Quality:** Excellent

Strengths:
- Singleton pattern correctly implemented
- Value clamping on server side (defense in depth)
- Console logging for debugging (line 51)

Code snippet (lines 44-52):
```typescript
updateSettings(newSettings: Partial<Settings>): void {
  if (newSettings.minNodesPerPlan !== undefined) {
    const value = Math.min(
      Math.max(newSettings.minNodesPerPlan, MIN_NODES_MIN),
      MIN_NODES_MAX
    );
    this.settings.minNodesPerPlan = value;
    console.error(`[Overture] Settings updated: minNodesPerPlan = ${value}`);
  }
}
```

#### 5. WebSocket Message Types (/packages/mcp-server/src/types.ts)
**Status:** PASS

- `sync_settings` message type defined (line 349)
- Type safety maintained

#### 6. WebSocket Server Handler (/packages/mcp-server/src/websocket/ws-server.ts)
**Status:** PASS

- Handler implemented (lines 463-467)
- Calls settingsStore.updateSettings() correctly

Code snippet:
```typescript
case 'sync_settings': {
  console.error('[Overture] Received settings sync:', message.settings);
  settingsStore.updateSettings(message.settings);
  break;
}
```

#### 7. Submit Plan Validation (/packages/mcp-server/src/tools/handlers.ts)
**Status:** PASS
**Quality:** Excellent

- Validation correctly implemented (lines 604-614)
- Clear error messages
- Plan data cleaned up on rejection
- Proper use of settingsStore.getMinNodesPerPlan()

Code snippet:
```typescript
const minNodesRequired = settingsStore.getMinNodesPerPlan();
if (nodes.length > 0 && nodes.length < minNodesRequired) {
  console.error(`[Overture] Plan rejected: ${nodes.length} nodes < minimum ${minNodesRequired}`);
  multiProjectPlanStore.clearProjectPlan(projectId);
  return {
    success: false,
    message: `Plan rejected: Only ${nodes.length} node(s) provided, but minimum ${minNodesRequired} node(s) required. Please create a more detailed plan.`,
    projectId
  };
}
```

#### 8. WebSocket Hook (/packages/ui/src/hooks/useWebSocket.ts)
**Status:** PASS (implementation)
**Issue:** syncSettings function exists but not exported/used

Strengths:
- Settings sync on connection (lines 500-507) ✓
- syncSettings helper function exists (lines 751-759) ✓

**PROBLEM:** syncSettings is defined but:
1. NOT exported from the hook
2. NOT called by SettingsModal
3. ONLY syncs on WebSocket connection, not on user save action

## Issues Found

### Critical Issue #1: Settings Not Synced on Save
**Severity:** CRITICAL
**Impact:** Feature non-functional for primary use case
**Location:** /packages/ui/src/components/Modals/SettingsModal.tsx line 29

**Problem:**
When user changes minimum nodes setting and clicks "Save Changes", the value is saved to localStorage but the server is NOT notified. This means:
1. The setting appears to save in the UI
2. The setting persists across refreshes
3. BUT server validation still uses old value (default: 1)
4. User submits plan thinking validation is active
5. Plan is accepted despite violating user's preference
6. User has false sense of security

**Root Cause:**
SettingsModal does not import or call the syncSettings function from useWebSocket.

**Current Code:**
```typescript
const handleSave = () => {
  setMinNodesPerPlan(localMinNodes);
  onClose();
};
```

**Required Fix:**
```typescript
import { useWebSocket } from '@/hooks/useWebSocket';

// In component:
const { syncSettings } = useWebSocket();

const handleSave = () => {
  setMinNodesPerPlan(localMinNodes);
  syncSettings();  // <-- MISSING LINE
  onClose();
};
```

**Reproduction Steps:**
1. Set min nodes to 5 in settings modal
2. Click "Save Changes"
3. Submit plan with 2 nodes via MCP tool
4. Expected: Plan rejected
5. Actual: Plan accepted (server still has default minNodesPerPlan: 1)

**Workaround:**
Disconnect and reconnect WebSocket after changing settings (triggers sync on connection).

## Additional Observations

### Positive Findings
1. **Defensive Programming:** Server-side clamping prevents invalid values even if UI bypassed
2. **Clear Error Messages:** Validation failure provides actionable feedback to agents
3. **Data Cleanup:** Rejected plans don't pollute the store
4. **Type Safety:** Full TypeScript coverage prevents common bugs
5. **UX Polish:** Modal animations, disabled states, proper focus handling

### Minor Suggestions
1. Add visual confirmation when settings saved (toast notification)
2. Add "Reset to Defaults" button in settings modal
3. Consider debouncing sync_settings messages (if user rapidly changes values)
4. Add settings version number for future migration support
5. Log settings changes to help debug validation issues

---

## Regression Risk Assessment

**Low Risk** - Once the sync bug is fixed:
- Settings store is isolated, doesn't affect existing features
- WebSocket message type added to union, backward compatible
- Server validation only rejects plans, doesn't break existing functionality
- UI components don't interfere with canvas or other critical paths

---

## Performance Considerations

**Excellent** - No performance concerns:
- localStorage writes are synchronous but fast
- WebSocket messages are tiny (~50 bytes)
- Settings only read once per plan submission
- No polling or continuous validation

---

## Security Considerations

**Good** - No security issues:
- Input validation on both client and server
- No user-controlled strings in error messages (just numbers)
- Settings stored in localStorage (appropriate for user preferences)
- No sensitive data in settings

## Recommendations

### Immediate Actions Required
1. **FIX CRITICAL BUG:** Add syncSettings() call to SettingsModal.handleSave()
2. **Export syncSettings:** Ensure useWebSocket hook exports syncSettings function
3. **Test end-to-end:** Verify setting change -> sync -> validation -> rejection flow
4. **Add integration test:** Automated test for settings sync on save

### Before Merging to Main
1. Run manual test protocol (see section below)
2. Verify WebSocket messages in browser console
3. Test with actual plan submission via MCP tool
4. Confirm validation error message is clear

### Future Enhancements
1. Add settings history/audit log
2. Implement settings export/import
3. Add more configurable settings (max nodes, timeout, etc.)
4. Create settings presets (strict, balanced, permissive)

---

## Manual Test Protocol

Since Playwright automation is unavailable, execute these steps manually:

### Pre-Test Setup
```bash
# Ensure servers are running
npm run dev

# Open browser to http://localhost:3031
# Open browser console (F12)
```

### Test Sequence

**Test 1: Settings Modal Opening**
1. Look for gear icon in header (top right area)
2. Click gear icon
3. Verify modal opens with "Settings" title
4. Verify modal contains "Minimum Nodes Per Plan" section
5. Verify number input with current value (default: 1)
6. Verify +/- buttons present
7. Verify "Cancel" and "Save Changes" buttons

**Test 2: Value Boundaries**
1. Click + button repeatedly until reaching 20
2. Verify + button becomes disabled at 20
3. Click - button repeatedly until reaching 1
4. Verify - button becomes disabled at 1
5. Try typing 0 in input - verify clamped to 1
6. Try typing 25 in input - verify clamped to 20

**Test 3: Cancel Functionality**
1. Set value to 5
2. Click "Cancel"
3. Reopen settings modal
4. Verify value is still 1 (not saved)

**Test 4: Save Functionality (EXPECTED TO FAIL)**
1. Set value to 5
2. Click "Save Changes"
3. Check browser console for WebSocket messages
4. **EXPECTED:** No sync_settings message (BUG!)
5. Reopen settings modal
6. Verify value is 5 (localStorage worked)

**Test 5: Persistence**
1. Set value to 3
2. Click "Save Changes"
3. Refresh page (F5)
4. Reopen settings modal
5. Verify value is still 3

**Test 6: WebSocket Sync on Connection**
1. Check browser console for "Received settings sync" on page load
2. Verify server logs show settings update

**Test 7: Plan Validation (AFTER FIX)**
1. Set min nodes to 5, save
2. Create test plan XML with 2 nodes
3. Submit via `/api/test-plan` endpoint or MCP tool
4. Verify plan is REJECTED
5. Verify error message: "Only 2 node(s) provided, but minimum 5 node(s) required"

**Test 8: Plan Validation - Pass**
1. Set min nodes to 2, save
2. Create test plan XML with 3 nodes
3. Submit plan
4. Verify plan is ACCEPTED and renders

## Memory Updates

Added to memory:
- Settings feature integration bug pattern (sync on save)
- WebSocket hook export/import requirements
- Settings validation flow: UI → WebSocket → Server → Validation
- Test files for minimum nodes validation

---

## Conclusion

**DO NOT MERGE** until critical sync bug is fixed.

The implementation shows excellent code quality and attention to detail, but the missing syncSettings call makes the feature non-functional for its primary use case. This is a classic integration bug where individual components work perfectly in isolation but fail when composed together.

**Estimated Fix Time:** 5 minutes (1 import + 1 function call + verify export)
**Re-Test Time:** 15 minutes (manual protocol execution)
**Risk Level:** Low (fix is trivial, well-understood)

Once fixed, this will be a solid, well-implemented feature that enhances AI agent control and user safety.
