```

### Feature Flag Rollback (Instant)

**When to use:** Quick revert during testing

```toml
# In Cargo.toml
[features]
default = ["marketplace-v1"]  # Revert from v2
```

- Scaling event

---

## 🛠️ Troubleshooting

### Common Issues

**1. Slow Search Queries**
- Check cache hit rate

- Increase cache size
- Review RDF query performance

**2. High Memory Usage**
- Reduce cache sizes
- Clear old entries
- Check for memory leaks

**3. Ed25519 Signature Failures**

- Validate PEM encoding

**4. RDF Store Errors**
- Verify disk space
- Check file permissions
- Validate RDF format
- Rebuild database if corrupted
