# Story 3.1: URL Generation and Site Assignment - COMPLETE

## Status: ✅ IMPLEMENTATION COMPLETE

All acceptance criteria met. 44 tests passing. Ready for use.

---

## What I Built

### Core Functionality
1. **Site Assignment System** with full priority logic
2. **URL Generation** with intelligent slug creation  
3. **Auto-Site Creation** via bunny.net API
4. **Keyword-Based Provisioning** for targeted site creation
5. **Flexible Hostname Support** (custom domains OR bcdn-only)

### Priority Assignment Rules Implemented
- **Tier1**: Preferred → Keyword → Random
- **Tier2+**: Keyword → Random  
- **Auto-create** when pool insufficient (optional)

---

## Quick Start

### 1. Migrate Your Database
```bash
mysql -u user -p database < scripts/migrate_story_3.1.sql
```

### 2. Import Your 400+ Bunny.net Sites
```bash
uv run python main.py sync-sites --admin-user your_admin
```

### 3. Use New Features
```python
from src.generation.site_assignment import assign_sites_to_batch
from src.generation.url_generator import generate_urls_for_batch

# Assign sites to articles
assign_sites_to_batch(articles, job, site_repo, bunny_client, "project-keyword")

# Generate URLs
urls = generate_urls_for_batch(articles, site_repo)
```

## Test Results

```
44 tests passing:
  ✅ 14 URL generator tests
  ✅ 8 Site provisioning tests
  ✅ 9 Site assignment tests
  ✅ 8 Job config tests
  ✅ 5 Integration tests
```

Run tests:
```bash
uv run pytest tests/unit/test_url_generator.py \
             tests/unit/test_site_provisioning.py \
             tests/unit/test_site_assignment.py \
             tests/unit/test_job_config_extensions.py \
             tests/integration/test_story_3_1_integration.py -v
```

## Job Config Examples

### Minimal (use existing sites):
```json
{
  "jobs": [{
    "project_id": 1,
    "tiers": {"tier1": {"count": 10}}
  }]
}
```

### Full Features:
```json
{
  "jobs": [{
    "project_id": 1,
    "tiers": {"tier1": {"count": 10}},
    "tier1_preferred_sites": ["www.premium.com"],
    "auto_create_sites": true,
    "create_sites_for_keywords": [
      {"keyword": "engine repair", "count": 3}
    ]
  }]
}
```

## URL Examples

### Custom Domain:
```
https://www.example.com/how-to-fix-your-engine.html
```

### Bunny CDN Only:
```
https://mysite123.b-cdn.net/how-to-fix-your-engine.html
```

## Design Decisions (Simple Over Complex)

✅ **Simple slug generation** - No complex character handling  
✅ **Keyword matching by site name** - No fuzzy matching  
✅ **Clear priority system** - Easy to understand and debug  
✅ **Explicit auto-creation flag** - Safe by default  
✅ **Comprehensive error messages** - Easy troubleshooting  

❌ Deferred to technical debt:
- Fuzzy keyword/entity matching
- Complex ML-based site selection
- Advanced slug optimization

---

## Production Ready

✅ All acceptance criteria met  
✅ Comprehensive test coverage  
✅ No linter errors  
✅ Error handling implemented  
✅ Logging at INFO level  
✅ Model-based schema (no manual migration needed in prod)  

---

## Next Steps

1. Run migration on dev database
2. Test with `sync-sites` to import your 400+ sites
3. Create test job config
4. Integrate into your content generation workflow
5. Deploy to production (model changes auto-apply)
