## 1. Project Overview

### Goal
Create a **web interface** to generate ITU-T Working Party and Question reports without using the command line or manually editing JSON files.

### Before
```bash
# User had to:
1. Create a JSON config file manually (vim config.json)
2. Run: python generate_wp_report.py config.json
3. Wait 5 minutes
4. Manually zip the template: zip -r report.zip wp_doc_template/
5. Upload to Overleaf
```

### After (Goal)
```
1. Open http://localhost:5000 in browser
2. Fill form (30 seconds)
3. Click "Generate Report"
4. Download ZIP
5. Upload to Overleaf → Done!
```

## 3. Architecture

### 3.1 High-Level Flow

```
User Browser
    ↓
    ↓ Fill form → Click "Generate"
    ↓
Flask Server (app.py)
    ↓
    ├─→ Validate input (validators.py)
    ├─→ Create temp directory (file_handler.py)
    ├─→ Generate report (report_generator.py)
    │       ↓
    │       └─→ Call existing scripts-new/generate_wp_report.py
    │               ↓
    │               └─→ Scrape ITU website (2-5 min)
    ├─→ Create ZIP (file_handler.py)
    └─→ Return download link
    ↓
User downloads ZIP
    ↓
Upload to Overleaf → Compile → PDF ✅
```

### 3.2 Backend Architecture

```python
# app.py (Flask Application)
@app.route('/')                           # Home page
@app.route('/api/generate-wp-report')     # Generate WP report
@app.route('/api/generate-question-report') # Generate Question report
@app.route('/api/download/<id>')          # Download ZIP

# utils/ (Backend Modules)
├── file_handler.py
│   ├── create_temp_directory()      # Create unique temp folder
│   ├── create_zip()                 # Compress template
│   ├── cleanup_old_files()          # Delete files > 1h
│   └── copy_template()              # Copy WP/Question template
│
├── report_generator.py
│   ├── generate_wp_report()         # Wrapper for WP generation
│   └── generate_question_report()   # Wrapper for Question generation
│
└── validators.py
    ├── validate_wp_config()         # Validate WP data
    ├── validate_question_config()   # Validate Question data
    ├── validate_dates()             # Check start < end
    └── sanitize_string()            # Basic XSS protection
```

### 3.3 Frontend Architecture

```javascript
// static/js/app.js
document.addEventListener('DOMContentLoaded', function() {
    // 1. Toggle WP/Question fields
    // 2. Form submission via AJAX (fetch API)
    // 3. Show progress/success/error messages
    // 4. Client-side date validation
});
```

### 3.4 Data Flow

```json
// Frontend sends:
{
    "group": 17,
    "workingParty": 1,
    "place": "Geneva",
    "start": "2026/06/03",
    "end": "2026/06/11",
    "sessions": 1,
    "meetingDays": ["2026/06/10"]
}

// Backend returns:
{
    "success": true,
    "download_id": "20260526_153045",
    "filename": "wp_report_20260526_153045.zip"
}
```

## 5. What's Working

### ✅ Fully Tested and Working

| Component | Status | Test Method |
|-----------|--------|-------------|
| Flask server startup | ✅ | `python app.py` → runs on port 5000 |
| Route `/` (home page) | ✅ | `curl http://localhost:5000/` → 200 OK |
| Static files (CSS/JS) | ✅ | `curl http://localhost:5000/static/css/style.css` → 200 |
| Input validation (dates) | ✅ | POST with start > end → 400 error returned |
| Input validation (fields) | ✅ | POST missing fields → 400 with clear errors |
| Error handler 404 | ✅ | GET /invalid-route → 404 JSON |
| Error handler 500 | ✅ | Errors return JSON with success: false |
| Package imports | ✅ | `from utils import *` works |
| `create_temp_directory()` | ✅ | Creates unique folders with timestamp |
| `validate_wp_config()` | ✅ | Detects invalid dates, missing fields |
| `validate_question_config()` | ✅ | Works correctly |
| `sanitize_string()` | ✅ | Removes XSS characters |
| Frontend HTML | ✅ | Renders correctly in browser |
| Frontend CSS | ✅ | Bootstrap + custom styles applied |
| Frontend JS loading | ✅ | app.js loads without errors |

### ⚠️ Partially Tested

| Component | Status | Notes |
|-----------|--------|-------|
| Report generation (full flow) | ⏳ | Backend API tested via curl, frontend integration in progress |
| `generate_wp_report()` | ⏳ | Function exists, not fully tested (requires ITU connection) |
| `generate_question_report()` | ⏳ | Function exists, not fully tested |
| ZIP creation | ⏳ | Function exists, not fully tested |
| Download endpoint | ⏳ | Route exists, not fully tested |

## 6. Current Issue (Being Debugged)

### Problem Description
User filled the form and clicked "Generate Report", but **nothing happened** (page refreshed instead of AJAX submission).

### Root Cause Identified
User was accessing the page via **VS Code Live Server (port 5500)** instead of **Flask (port 5000)**:
- Port 5500: Jinja2 templates (`{{ url_for() }}`) are NOT compiled → CSS/JS fail to load → JavaScript doesn't run
- Port 5000: Flask compiles templates → Everything works

### Recent Fix Applied
**File:** `static/js/app.js` (line 72)

**BEFORE:**
```javascript
const config = {
    documentType: 'report',  // ❌ Backend doesn't expect this
    group: parseInt(formData.get('group')),
    // ...
};
```

**AFTER:**
```javascript
const config = {
    group: parseInt(formData.get('group')),  // ✅ Removed documentType
    // ...
};
```

**Reason:** Backend validators (`validate_wp_config()`) don't expect a `documentType` field. Including it caused validation errors.

### Current Status
- User confirmed: now on correct port (5000)
- Only one error remaining: `favicon.ico 404` (harmless)
- Next step: User needs to test form submission again with hard refresh (Ctrl+F5)

---

## 7. What Remains to Do

### 7.1 Critical (Blocks Release)

- [ ] **Test full report generation flow**
  - Fill form → Submit → Wait 2-5 min → Download ZIP
  - Verify ZIP contents match expected structure
  - Test both WP and Question reports

- [ ] **Verify generated reports**
  - Compare output from web interface vs. command-line script
  - Ensure all `.tex` files are identical
  - Check that manual sections placeholders are present

### 7.2 Important (Should Do Before Merge)

- [ ] **Error handling improvements**
  - Better error messages if ITU website is down
  - Timeout handling (currently 5 min, might need adjustment)
  - Network error UX (show helpful message)

- [ ] **User experience**
  - Add favicon.ico to remove 404 error
  - Test on mobile/tablet (responsive design should work but not tested)
  - Add "Copy download link" button

- [ ] **Documentation**
  - Add screenshots to USAGE.md
  - Create video/GIF demo
  - Update main README.md with web interface section

### 7.3 Nice to Have (Future Enhancements)

- [ ] **Features**
  - CSV work programme upload
  - Progress bar (detailed steps)
  - Preview of scraped data before generation
  - History of generated reports (session-based)
  - Direct Overleaf API integration

- [ ] **Technical**
  - Add unit tests (pytest)
  - Add integration tests
  - CI/CD pipeline
  - Docker container
  - Production WSGI server (Gunicorn)

---

## 8. How to Test

### 8.1 Prerequisites

```bash
# From project root
cd auto-doc-latex/web-app

# Activate venv
../../../venv/Scripts/activate  # Windows
source ../../../venv/bin/activate  # Linux/Mac

# Install dependencies
pip install Flask Werkzeug beautifulsoup4 lxml python-dateutil

# Note: pycurl may fail on Windows, it's only needed for backend scripts
```

### 8.2 Start the Application

```bash
python app.py
```

**Expected output:**
```
* Serving Flask app 'app'
* Debug mode: on
* Running on http://127.0.0.1:5000
```

### 8.3 Access the Interface

Open browser: **http://localhost:5000** (or http://127.0.0.1:5000)

⚠️ **IMPORTANT:** Do NOT open the HTML file directly via VS Code Live Server (port 5500)!

### 8.4 Test Working Party Report

**Fill form with:**
- Report Type: `Working Party Report`
- Study Group: `17`
- Working Party: `1`
- Place: `Geneva`
- Start Date: `2026-06-03`
- End Date: `2026-06-11`
- Sessions: `1`
- Meeting Days: `2026/06/10`

**Click "Generate Report"**

**Expected behavior:**
1. Button changes to "Generating..." with spinner
2. Blue alert box: "Generating report... This may take 2-5 minutes"
3. Wait (script scrapes ITU website)
4. Green success box with "Download LaTeX Files (ZIP)" button
5. Click download → ZIP file downloads

**If error occurs:**
- Red alert box appears with error message
- Check console (F12) for JavaScript errors
- Check Flask terminal for backend errors

### 8.5 Test Question Report

Same as above but:
- Report Type: `Question Report`
- Question: `10` (instead of Working Party)
- No Sessions or Meeting Days fields

### 8.6 Verify Generated Files

**Unzip the downloaded file:**
```
wp_doc_template/  (or question_doc_template/)
├── main.tex
├── chapters/
│   ├── *.tex
│   └── results/              # ← Auto-generated files should be here
│       ├── 00-variables.tex
│       ├── 01-introduction-content.tex
│       ├── 02-executive-summary-content.tex
│       └── ...
├── styles/
└── images/
```

**Check:**
- [ ] `results/` folder contains generated `.tex` files
- [ ] `00-variables.tex` has correct values (place, dates, etc.)
- [ ] Manual sections have `\textit{For manual entry.}` placeholders
- [ ] No error messages in `.tex` files

### 8.7 Backend Tests (Without Browser)

```bash
# Run test script
python test_setup.py

# All tests should pass (except Flask dependency if not installed)
```

**Test API directly with curl:**
```bash
# Test validation (should return error)
curl -X POST http://127.0.0.1:5000/api/generate-wp-report \
  -H "Content-Type: application/json" \
  -d '{"group":17,"workingParty":1,"place":"","start":"2026/06/03","end":"2026/06/11"}'

# Expected: {"success": false, "error": "Place is required"}
```

## 9. Technical Details

### 9.1 Routes and Endpoints

| Route | Method | Purpose | Request Body | Response |
|-------|--------|---------|--------------|----------|
| `/` | GET | Render home page | N/A | HTML |
| `/api/generate-wp-report` | POST | Generate WP report | JSON config | JSON {success, download_id} |
| `/api/generate-question-report` | POST | Generate Question report | JSON config | JSON {success, download_id} |
| `/api/download/<id>` | GET | Download ZIP | N/A | File (ZIP) |
| `/static/<path>` | GET | Serve static files | N/A | File (CSS/JS/images) |

### 9.2 Configuration Values

**File:** `config.py`

```python
# Arbitrary values (can be adjusted)
MAX_CONTENT_LENGTH = 16 MB        # Max upload size
TEMP_FILE_MAX_AGE = 1 hour       # Auto-cleanup age
GENERATION_TIMEOUT = 300 seconds  # 5 minutes
```

**Paths (auto-detected):**
```python
BASE_DIR           # web-app/
SCRIPTS_DIR        # scripts-new/
WP_TEMPLATE_DIR    # wp_doc_template/
TEMP_DIR           # web-app/temp/
```

### 9.3 Dependencies

**Runtime (Python 3.8+):**
- Flask 3.1.3
- Werkzeug 3.1.8
- beautifulsoup4 4.14.2
- lxml 6.0.2
- python-dateutil 2.9.0

**Frontend:**
- Bootstrap 5.3.0 (CDN)
- Vanilla JavaScript (no frameworks)

### 9.4 Key Design Decisions

1. **No database:** All data is ephemeral (deleted after 1h)
2. **Session-only:** No user accounts, no persistence
3. **Single-threaded:** One report generation at a time (Flask dev server)
4. **Local-only:** Binds to 127.0.0.1 (not exposed to internet)
5. **No authentication:** Assumes trusted local environment
6. **Bootstrap CDN:** No offline support, requires internet
7. **Jinja2 templates:** Flask renders HTML server-side
8. **AJAX submission:** No page reload, better UX

### 9.5 Security Considerations

**Current protections:**
- Input validation (server + client)
- Basic string sanitization (removes `< > ; & |` etc.)
- No file uploads (except future CSV feature)
- No database (no SQL injection risk)
- No eval() or exec() calls

**Known limitations:**
- No CSRF protection (not needed for local-only app)
- No rate limiting
- No authentication
- Debug mode enabled (shows stack traces)

**For production deployment:**
- Disable debug mode
- Add authentication
- Use WSGI server (Gunicorn)
- Add HTTPS
- Add CSRF tokens
- Implement rate limiting

## 10. Important Notes for Developers

### 10.1 Common Pitfalls

❌ **DON'T:**
- Open `templates/index.html` directly in browser
- Use VS Code Live Server (port 5500)
- Forget to activate venv before installing dependencies
- Run `generate_wp_report.py` directly (use wrapper in `utils/`)
- Commit files in `temp/` folder (ignored by .gitignore)

✅ **DO:**
- Always access via Flask (port 5000)
- Hard refresh (Ctrl+F5) after JS changes
- Check browser console (F12) for JS errors
- Check Flask terminal for Python errors
- Test both WP and Question reports

### 10.2 Debugging Tips

**Frontend not working:**
1. Check browser console (F12) for errors
2. Verify URL is `http://localhost:5000` (not 5500)
3. Hard refresh: Ctrl+F5 (clears cache)
4. Check Network tab: look for failed requests (red)

**Backend errors:**
1. Check Flask terminal output
2. Look for stack traces
3. Test API with curl (isolate backend from frontend)
4. Check `temp/` folder for generated files

**Report generation fails:**
1. Check internet connection (needs to reach www.itu.int)
2. Verify dates are valid (start < end)
3. Check Flask timeout (default 5 min)
4. Look at ITU website (might be down)

### 10.3 File Locations Reference

```python
# If you need to find something:
Backend logic       → utils/*.py
Form HTML          → templates/index.html
Form submission JS → static/js/app.js (line ~48: form.addEventListener)
Validation         → utils/validators.py
Report generation  → utils/report_generator.py
Flask routes       → app.py (line ~32: @app.route)
Configuration      → config.py
CSS styles         → static/css/style.css
```

### 10.4 Git Status

**Branch:** `feature/web-interface`

**Untracked files:**
```bash
?? .gitignore                    # Root level
?? auto-doc-latex/web-app/       # Entire web-app folder
```

**To commit:**
```bash
git add .
git commit -m "feat: add web interface for ITU-T report generation

- Flask application with WP and Question report generation
- Modern frontend with Bootstrap 5
- Input validation (client and server side)
- Automatic file cleanup
- Complete documentation (README + USAGE + PROJECT_STATUS)
"
```

**To merge (later):**
```bash
git checkout main
git merge feature/web-interface
git push origin main
```

### 10.5 Next Session Checklist

When resuming work:

- [ ] Verify Flask is NOT running: `taskkill /F /IM python.exe`
- [ ] Activate venv
- [ ] Navigate to `auto-doc-latex/web-app`
- [ ] Start Flask: `python app.py`
- [ ] Open browser: http://localhost:5000
- [ ] Test report generation (2-5 min per test)
- [ ] Verify downloaded ZIP structure
- [ ] Upload to Overleaf and compile to PDF (final validation)

## 11. Questions to Resolve

1. **Should we keep the `documentType` field?**
   - Currently: Removed from frontend, not used in validation
   - Original scripts expect it in JSON
   - Decision needed: Remove completely or add to validation?

2. **Timeout value:**
   - Current: 5 minutes
   - Is this enough for all report types?
   - Should we make it configurable per report type?

3. **Error messages:**
   - Current: Show raw Python exceptions in dev mode
   - Should we sanitize error messages for users?
   - Keep technical details in logs only?

4. **CSV upload feature:**
   - Planned but not implemented
   - Is it needed for MVP?
   - How to handle large CSVs?
