## Current State: MinIO File Upload Implementation

### Completed Work

#### 1. Docker Compose - MinIO Service Added
- File: `deployments/docker-compose.yaml`
- Added MinIO service with versioning enabled
- Configured healthcheck and environment variables
- Note: Using `minio/minio:RELEASE.2024-01-16T16-07-38Z` for CPU compatibility

#### 2. API Endpoints - File Upload/Download
- File: `internal/api/handlers.go`

| Endpoint | Method | Description |
|----------|--------|-------------|
| `/api/items/{partNumber}/file` | POST | Upload file and create revision |
| `/api/items/{partNumber}/file` | GET | Download latest revision file |
| `/api/items/{partNumber}/file/{revision}` | GET | Download specific revision file |
| `/api/items/{partNumber}/revisions` | POST | Create revision without file |

#### 3. Routes Added
- File: `internal/api/routes.go`
- All new endpoints wired up

#### 4. FreeCAD Client Updated
- File: `pkg/freecad/silo_commands.py`
- Added `_upload_file()` method for multipart form upload
- Updated `create_revision()` to optionally upload files
- Updated `Silo_Commit` command to save document and upload to MinIO

#### 5. Build Status
- **Go code compiles successfully** - `go build ./...` passes

## Where We Left Off

### Problem
MinIO container failing to start due to CPU architecture:
```
Fatal glibc error: CPU does not support x86-64-v2
```

### Solution in Progress
- VM being rebooted to newer architecture
- Already configured older MinIO image as fallback

---

## Next Steps After VM Reboot

### 1. Start Services
```bash
cd /home/forbes/projects/silo-0062/deployments
sudo docker compose up -d
```

### 2. Verify Services
```bash
# Check all services
sudo docker compose ps

# Check MinIO health
curl http://localhost:9000/minio/health/live

# Check Silo API with storage
curl http://localhost:8080/ready
```

### 3. Test File Upload
```bash
# Create test file
echo "Test content" > /tmp/test.FCStd

# Upload to existing item
curl -X POST \
  -F "file=@/tmp/test.FCStd" \
  -F "comment=Test upload" \
  -F 'properties={"test": true}' \
  http://localhost:8080/api/items/3DX15-A01-0002/file
```

### 4. Test File Download
```bash
# Download latest revision
curl http://localhost:8080/api/items/3DX15-A01-0002/file -o downloaded.FCStd

# Download specific revision
curl http://localhost:8080/api/items/3DX15-A01-0002/file/2 -o rev2.FCStd
```

### 5. Test from FreeCAD
1. Open FreeCAD with Silo workbench
2. Open an existing item: `Silo_Open` command
3. Make changes
4. Commit with file upload: `Silo_Commit` command
5. Verify file appears in MinIO console at http://localhost:9001
