## 1. Development Overview
|
|
|
|

|
|
|
|
- ✅ V11 UI pixel-perfect implementation (Gemini-style design)
|
|
- ✅ Multi-task support (multiple analyses in single session)
|
|
- ✅ Single-page scrolling workspace layout
|
|
- ✅ Input box overlay bug fix (scroll spacer solution)
|
|
- ✅ Word document export functionality
|
|
- ✅ Full end-to-end integration testing passed
|
|
|

|
|
|
|
## 2. Completed Features
|
|
|
|
### 2.1 V11 UI Implementation
|
|
|
|
| Component | Description | Status |
|
|
|-----------|-------------|--------|
|
|
| `SSAWorkspace.tsx` | Main workspace container | ✅ |
|
|
| `SSASidebar.tsx` | Left collapsible sidebar | ✅ |
|
|
| `SSAChatPane.tsx` | Central chat area | ✅ |
|
|
| `SSAWorkspacePane.tsx` | Right dynamic workspace | ✅ |
|
|
| `SSACodeModal.tsx` | R code viewer modal | ✅ |
|
|
| `SSAToast.tsx` | Global toast notifications | ✅ |
|
|
| `TypeWriter.tsx` | Typewriter effect for AI responses | ✅ |
|
|
|
|
### 2.2 Multi-Task Support
|
|
|
|
- **Store Extension**: Added `analysisHistory: AnalysisRecord[]` and `currentRecordId`
|
|
- **Record Management**: `addAnalysisRecord`, `updateAnalysisRecord`, `selectAnalysisRecord`
|
|
- **Card Linking**: Chat cards carry `recordId` for task switching
|
|
- **State Sync**: Phase state correctly syncs when switching records
|
|
|
|
### 2.3 Single-Page Scrolling Layout
|
|
|
|
- Replaced tab-based switching with single-page scrolling
|
|
- Step progress bar: `Analysis Plan → Executing → Results`
|
|
- Section dividers between SAP, execution log, and results
|
|
- Auto-scroll to relevant section during execution
|
|
|
|
### 2.4 Input Box Overlay Fix
|
|
|
|
**Root Cause**: Flexbox layout ignores child element's `padding-bottom` for scroll calculation
|
|
|
|
**Solution**: Physical scroll spacer element
|
|
|
|
```tsx
|
|
<div ref={chatEndRef} className="scroll-spacer" />
|
|
```
|
|
|
|
```css
|
|
.scroll-spacer {
|
|
height: 220px;
|
|
width: 100%;
|
|
flex-shrink: 0;
|
|
}
|
|
```
|
|
|
|
### 2.5 Word Document Export
|
|
|
|
- Implemented using `docx` library
|
|
- Report structure: Data description → Method → Prerequisites → Descriptive stats → Results → Chart → Conclusion
|
|
- Dynamic filename: `统计分析报告_{dataFileName}_{datetime}.docx`
|
|
- Embedded chart images
|
|

## 3. Backend Changes
|
|
|
|
### 3.1 Plan Message Persistence
|
|
|
|
Added plan message saving in `/plan` route:
|
|
|
|
```typescript
|
|
await prisma.ssaMessage.create({
|
|
data: {
|
|
sessionId: id,
|
|
role: 'assistant',
|
|
contentType: 'plan',
|
|
content: { ...mockPlan, query }
|
|
}
|
|
});
|
|
```
|
|
|
|
### 3.2 Dynamic Filename in R Code
|
|
|
|
- `RClientService.ts`: Extract original filename from session
|
|
- `t_test_ind.R`: Use `input$original_filename` in generated code
|
|
|
|
### 3.3 Data Format Transformation
|
|
|
|
- Backend converts snake_case to camelCase for frontend
|
|
- Plots array transformation (raw base64 → structured objects)
|
|

## 4. Bug Fixes
|
|
|
|
| Issue | Root Cause | Solution |
|
|
|-------|------------|----------|
|
|
| Input box overlay | Flexbox padding-bottom ignored | Scroll spacer element |
|
|
| Multi-task state confusion | Phase state not reset on switch | useEffect on currentRecordId |
|
|
| Variable names hardcoded | Not reading from plan parameters | Dynamic extraction with fallback |
|
|
| P-value not displaying | snake_case/camelCase mismatch | Backend transformation |
|
|
| Image loading failure | Raw base64 string format | Frontend/backend transformation |
|
|
| R code wrong filename | Hardcoded "your_data.csv" | Pass original_filename to R service |
|

## 7. Next Steps (Recommendations)
|
|
|
|
1. **Additional Statistical Methods**: Extend beyond T-test to ANOVA, Chi-square, etc.
|
|
2. **SSE Streaming**: Real-time execution log streaming
|
|
3. **History Persistence**: Save analysis history to database
|
|
4. **Error Boundary**: Better error handling and recovery
|
|
5. **Accessibility**: Keyboard navigation improvements
|

## 8. Technical Notes
|
|
|
|
### Pointer Events Solution
|
|
|
|
```css
|
|
.chat-input-wrapper {
|
|
pointer-events: none; /* Gradient overlay passes through */
|
|
}
|
|
.chat-input-container {
|
|
pointer-events: auto; /* Container restores click */
|
|
}
|
|
.input-box {
|
|
pointer-events: auto; /* Input box clickable */
|
|
}
|
|
```
|
|
|
|
### Scroll Spacer Solution
|
|
|
|
Physical DOM element replaces CSS padding-bottom which is ignored in Flexbox:
|
|
|
|
```tsx
|
|
<div ref={chatEndRef} className="scroll-spacer" />
|
|
```
|
|
|
|
This ensures bottom content is always scrollable above the floating input box.
