- **New**: Add Ray for distributed Python
- **Recommendation**: Add Ray for scalability

### 11. Specialized Databases
**pheno-sdk**: QuestDB (timeseries), Memgraph (graph)
- **QuestDB**: 10x faster than InfluxDB
- **Memgraph**: 4x faster than Neo4j
- **Recommendation**: Add for specialized use cases

### 12. Infrastructure as Code
**pheno-sdk**: Pulumi + Cloudflare
- **New**: Add Pulumi for IaC
- **New**: Add Cloudflare API for tunnels/DNS
- **Recommendation**: Add for infrastructure management

### 13. Security & Secrets
**pheno-sdk**: SOPS, Age, Authlib, PyCasbin
- **SOPS**: Secrets encryption
- **Age**: Modern encryption
- **Authlib**: OAuth/OIDC
- **PyCasbin**: RBAC/ABAC
- **Recommendation**: Add for enterprise security

### 14. Pre-commit Hooks
**Current**: pre-commit (TraceRTM)
**pheno-sdk**: prek (replacement)
- **prek**: Better pre-commit alternative
- **Recommendation**: Consider prek as upgrade

### 15. Semantic Release
**pheno-sdk**: python-semantic-release
- **New**: Add for automated versioning
- **Recommendation**: Add for CI/CD automation
