- [x] All data files in `data/` or `support/` directories
- [x] Verification script passes: `python scripts/final_production_verification.py`

**Verification Command**:
```bash
python scripts/final_production_verification.py
```
**Expected**: ✅ PRODUCTION READY - ALL CHECKS PASSED

---

### 2. Documentation Accuracy ✅

- [x] Virtual environment instructions included
- [x] Standalone verification step added
- [x] All code references verified against actual codebase
- [x] File paths documented correctly
- [x] DEPLOYMENT_GUIDE.md created

**Key Updates**:
- Column count: 83 → 79 (after cleanup)
- Added venv setup instructions
- Added verification step in installation
- Updated Quick Reference section

---

### 3. Code Evidence Verification ✅
- [x] All code snippets match actual codebase
- [x] Line numbers accurate
- [x] File paths verified
- [x] Function signatures correct

**Verified Files**:
- `main.py` - All references accurate
- `services/data_loader.py` - Paths relative
- `services/simulator.py` - Code evidence verified
- `scripts/prepare_data.py` - Paths relative
- `run_complete_pipeline.py` - Paths relative

---

### 4. File Structure ✅
- [x] All required files present
- [x] Support files in `support/` folder
- [x] Data files in `data/` folder
- [x] Scripts in `scripts/` folder
- [x] Services in `services/` folder

**Required Files**:
- ✅ `data/AllQuestions.xlsx`
- ✅ `data/merged_personas.xlsx` (generated)
- ✅ `support/3000-students.xlsx`
- ✅ `support/3000_students_output.xlsx`
- ✅ `support/fixed_3k_personas.xlsx`

---

### 5. Virtual Environment Compatibility ✅
- [x] Works with `python -m venv venv`
- [x] Activation instructions for Windows/macOS/Linux
- [x] Dependencies clearly listed
- [x] No system-level dependencies

**Test Command**:
```bash
python -m venv venv
venv\Scripts\activate  # Windows
pip install pandas anthropic openpyxl python-dotenv
python check_api.py
```

---

### 6. Cross-Platform Compatibility ✅
- [x] Windows: Tested and verified
- [x] macOS/Linux: Compatible (uses pathlib)
- [x] Path separators: Handled automatically
- [x] Encoding: UTF-8 with Windows console fix

---

## Production Deployment Steps

### Step 1: Copy Project
```bash
# Copy entire Simulated_Assessment_Engine folder to target location
cp -r Simulated_Assessment_Engine /target/location/
```

### Step 2: Set Up Environment
```bash
cd Simulated_Assessment_Engine
python -m venv venv
venv\Scripts\activate  # Windows
source venv/bin/activate  # macOS/Linux
pip install pandas anthropic openpyxl python-dotenv
```

### Step 3: Configure API Key
```bash
# Create .env file
echo "ANTHROPIC_API_KEY=sk-ant-api03-..." > .env
```

### Step 4: Verify Standalone Status
```bash
python scripts/final_production_verification.py
# Expected: ✅ PRODUCTION READY - ALL CHECKS PASSED
```

### Step 5: Prepare Data
```bash
# Ensure support files exist, then:
python scripts/prepare_data.py
# Creates: data/merged_personas.xlsx (79 columns, 3000 rows)
```

### Step 6: Run Pipeline
```bash
# Option A: Complete pipeline
python run_complete_pipeline.py --all

# Option B: Individual steps
python main.py --full
python scripts/comprehensive_post_processor.py
```
