## First-Run Network Requirement

Vestige downloads the **Nomic Embed Text v1.5** model (~130MB) from Hugging Face on first use.

**All subsequent runs are fully offline.**

### Model Cache Location

The embedding model is cached in platform-specific directories:

| Platform | Cache Location |
|----------|----------------|
| macOS | `~/Library/Caches/com.vestige.core/fastembed` |
| Linux | `~/.cache/vestige/fastembed` |
| Windows | `%LOCALAPPDATA%\vestige\cache\fastembed` |

Override with environment variable:
```bash
export FASTEMBED_CACHE_PATH="/custom/path"
```

---

## Environment Variables

| Variable | Default | Description |
|----------|---------|-------------|
| `VESTIGE_DATA_DIR` | Platform default | Custom database location |
| `VESTIGE_LOG_LEVEL` | `info` | Logging verbosity |
| `RUST_LOG` | - | Detailed tracing output |
| `FASTEMBED_CACHE_PATH` | `./.fastembed_cache` | Embedding model cache location |

---

## Command-Line Options

```bash
vestige-mcp --data-dir /custom/path   # Custom storage location
vestige-mcp --help                     # Show all options
```

---

## CLI Commands (v1.1+)

Stats and maintenance were moved from MCP to CLI to minimize context window usage:

```bash
vestige stats              # Memory statistics
vestige stats --tagging    # Retention distribution
vestige stats --states     # Cognitive state distribution
vestige health             # System health check
vestige consolidate        # Run memory maintenance
vestige restore <file>     # Restore from backup
```
