## 📋 Pre-Deployment Steps

### 1. Local Testing (Optional but Recommended)

```powershell
cd huggingface-space-v2
pip install -r requirements.txt
python app.py
```

**Test:**
- [ ] App launches without errors
- [ ] UI loads correctly
- [ ] Can enter prompt
- [ ] Can select quality
- [ ] Generate button works

### 2. Create New HF Space

Go to: https://huggingface.co/new-space

**Settings:**
- [ ] Space name: `game-asset-generator-pro-v2` (or your choice)
- [ ] License: MIT
- [ ] SDK: Gradio
- [ ] SDK Version: 4.44.0
- [ ] Hardware: L4 GPU (24GB VRAM)
- [ ] Visibility: Public or Private

### 3. Clone Space Repository

```powershell
git clone https://huggingface.co/spaces/YOUR_USERNAME/SPACE_NAME
cd SPACE_NAME
```

### 4. Copy Files

**Option A: Manual Copy**
```powershell
Copy-Item -Recurse D:\KIRO\Projects\XStudios\huggingface-space-v2\* .
```

**Option B: Use Script**
```powershell
cd D:\KIRO\Projects\XStudios\huggingface-space-v2
.\QUICK_DEPLOY.ps1 -SpaceURL "https://huggingface.co/spaces/YOUR_USERNAME/SPACE_NAME"
```

### 5. Verify Files

```powershell
Get-ChildItem -Recurse
```

**Should see:**
- [ ] app.py
- [ ] requirements.txt
- [ ] Dockerfile
- [ ] .gitignore
- [ ] README.md (with HF metadata header)
- [ ] core/ directory
- [ ] generators/ directory
- [ ] processors/ directory
- [ ] utils/ directory
- [ ] scripts/ directory

### 6. Update README Header

Ensure `README.md` starts with:
```yaml
---
title: 3D Asset Generator Pro V2
emoji: 🎮
colorFrom: blue
colorTo: purple
sdk: gradio
sdk_version: 4.44.0
app_file: app.py
pinned: false
license: mit
hardware: l4
---
```

### 7. Push to HF Space

```powershell
git add .
git commit -m "Initial deployment - Streamlined architecture"
git push
```

### 8. Monitor Build

1. Go to Space URL
2. Watch build logs
3. Wait for "Running" status (~5-10 minutes)

**Build should:**
- [ ] Install dependencies
- [ ] Install Blender
- [ ] Start Gradio app
- [ ] Show "Running" status

## 🧪 Post-Deployment Testing

### Basic Functionality

1. **Open Space URL**
   - [ ] UI loads correctly
   - [ ] No console errors

2. **Test Generation (Fast)**
   - [ ] Prompt: "medieval knight"
   - [ ] Quality: Fast
   - [ ] Click Generate
   - [ ] Wait ~45 seconds
   - [ ] 3D model appears
   - [ ] Status shows success

3. **Test Caching**
   - [ ] Same prompt again
   - [ ] Should be instant
   - [ ] Status: "Loaded from cache"

4. **Test Quality Presets**
   - [ ] Fast (~45s)
   - [ ] Balanced (~60s)
   - [ ] High (~90s)
   - [ ] Ultra (~120s)

### Error Handling

5. **Test Invalid Inputs**
   - [ ] Empty prompt → Error message
   - [ ] Very long prompt → Error message
   - [ ] Forbidden chars `<script>` → Error message

6. **Test Rate Limiting**
   - [ ] Make 11 requests quickly
   - [ ] 11th should be rate limited

### Advanced Features

7. **Test Blender Optimization**
   - [ ] Check logs for "Blender found"
   - [ ] Verify optimization runs
   - [ ] Check output file size

8. **Test Examples**
   - [ ] Click example prompts
   - [ ] Verify they work

## 📊 Performance Metrics

After 1 hour of testing:

- [ ] Generation success rate: >95%
- [ ] Average generation time: <90s (High quality)
- [ ] Cache hit rate: >50%
- [ ] Error rate: <5%
- [ ] GPU memory usage: <20GB
- [ ] No OOM errors

## 🐛 Troubleshooting

### Build Fails

**Check:**
- [ ] requirements.txt has all dependencies
- [ ] Dockerfile syntax is correct
- [ ] No import errors in code

**Fix:**
```powershell
# Test locally first
pip install -r requirements.txt
python app.py
```

### Runtime Errors

**Check Space logs:**
- [ ] Click "Logs" tab
- [ ] Look for error messages
- [ ] Check GPU memory usage

**Common issues:**
- OOM → Reduce quality presets
- Timeout → Increase GPU duration
- API errors → Check Hunyuan3D status

### Blender Not Working

**Check:**
- [ ] Dockerfile installs Blender
- [ ] BLENDER_PATH is set correctly
- [ ] Blender script is executable

**Fallback:**
- Space will work without Blender
- Just skips optimization step

## ✨ Success Criteria

**Space is successful if:**
- ✅ Builds without errors
- ✅ UI loads correctly
- ✅ Generates assets successfully
- ✅ Caching works
- ✅ No OOM errors
- ✅ Performance is good
- ✅ Error messages are clear

## 📈 Next Steps

After successful deployment:

1. **Share Space**
   - [ ] Share URL with team
   - [ ] Add to project documentation

2. **Monitor Performance**
   - [ ] Check daily for 1 week
   - [ ] Review error logs
   - [ ] Collect user feedback

3. **Optimize**
   - [ ] Adjust quality presets if needed
   - [ ] Tune cache settings
   - [ ] Add features based on feedback

4. **Consider Migration**
   - [ ] If all goes well for 1 week
   - [ ] Migrate old Space to new architecture
   - [ ] Or keep both running

## 🎉 Deployment Complete!

Once all checkboxes are ✅, your new Space is ready!

**Space URL:** `https://huggingface.co/spaces/YOUR_USERNAME/SPACE_NAME`

**Key Features:**
- 61% less code (2,481 → 960 lines)
- Modern architecture (async/await, type hints)
- Clean structure (modular, testable)
- Same features (FLUX, Hunyuan3D, Blender, caching)
- Better maintainability

**Enjoy your streamlined 3D asset generator! 🎮**
