`onFreezeChanged(refId: ID!)` - `onPolicyUpdated(token: String!)` ## Package Manager ✅ **pnpm** is now the default package manager: - ✅ Workspace configuration (`pnpm-workspace.yaml`) - ✅ All documentation updated to use pnpm - ✅ All scripts updated to use pnpm - ✅ Dockerfiles updated to use pnpm - ✅ Makefiles updated to use pnpm ## Next Steps 1. **Database Integration**: Replace in-memory stores with database (PostgreSQL/MongoDB) 2. **Event Indexing**: Implement blockchain event indexing for off-chain state 3. **Enhanced Error Handling**: Map Solidity reason codes to HTTP status codes 4. **Rate Limiting**: Implement rate limiting middleware 5. **Request Logging**: Add comprehensive request/response logging 6. **Metrics & Observability**: Add OpenTelemetry integration 7. **Testing**: Expand integration and unit tests 8. **Production Deployment**: Configure for production environments ## Notes - In-memory stores are used for development/testing. Production should use persistent databases. - Blockchain client requires contract addresses via environment variables. - Some services have placeholder implementations that should be enhanced with actual business logic. - GraphQL resolvers delegate to REST service layer for consistency.
