## 🔄 GitHub Actions Workflows

### CI/CD Pipelines ✅

| Workflow | Purpose | Trigger |
|----------|---------|---------|
| **ci.yml** | Continuous integration | Push, PR |
| **test.yml** | Comprehensive testing | Push, PR, Manual |
| **publish-pypi.yml** | PyPI publishing | Tag push, Release |

### Publishing Process

**PyPI**:
- Tag format: `2.0.0` (no 'v' prefix)
- Trigger: `git tag 2.0.0 && git push origin 2.0.0`
- Result: `pip install gbcms==2.0.0`

**Docker**:
- Same tag trigger
- Result: `docker pull ghcr.io/msk-access/gbcms:2.0.0`

## ✅ Package Validation

### Import Test

```python
# Should work after installation
import gbcms
from gbcms.cli import app
from gbcms.config import Config
```

### Entry Point Test

```bash
# Should work after installation
gbcms --help
gbcms version
```

### Package Metadata

```python
import gbcms
print(gbcms.__version__)  # Should show 2.0.0
print(gbcms.__author__)   # Should show MSK-ACCESS
```

## 🎯 Project Naming Convention

### Repository vs Package

| Aspect | Repository | Package | Status |
|--------|------------|---------|--------|
| **Name** | `windsurf-project` | `gbcms` | ✅ Correct |
| **GitHub URL** | `msk-access/windsurf-project` | N/A | ✅ Fine |
| **Package URL** | N/A | `msk-access/gbcms` | ✅ Correct |
| **Install Command** | N/A | `pip install gbcms` | ✅ Correct |

**This is the correct structure!** ✅

### Why This Works

1. **Repository name** can be descriptive (`windsurf-project`)
2. **Package name** is what users install (`gbcms`)
3. **URLs** point to correct GitHub repository
4. **No conflicts** with existing packages
