 - Ensure tests cover the new functionality and avoid sensitive data in tests.
 
 Next steps
+- Extend the DSL with richer constraints (VaR, VaR-CVaR, liquidity, latency) and ExecutionPolicy primitives.
+- Integrate the GoC registry and build a canonical EquiIR representation with per-message metadata for replay/verification.
+- Add a lightweight delta-sync coordinator and starter adapters for data feeds and brokers.
+- Expand the test suite to exercise the new backtester and Graph-of-Contracts scaffolds.
+- Improve packaging and docs to support publishing to a Python package index.
+- Implement a more expressive DSL and a richer IR (EquiIR) representation.
+- Add more tests for edge cases and simple integration tests for the CLI.
+- Expand packaging metadata and README with a longer developer and user guide.
+- Add a first-pass Graph-of-Contracts registry scaffold (GoC) and a minimal adapter registry.
+- Documentation: GoC overview and how to plug in new adapters.
+
+Extensibility notes
+- The repository now includes a small GoC registry module (equicompiler_algebraic_portfolio_dsl_to_/goc_registry.py) and a registry-aware GoC skeleton integrated into the IR formation flow. This provides a stable extension point for future adapters (data feeds, brokers) and verifiable contract graphs.
+- You can register adapters via the GoCRegistry class and view a digest that helps ensure reproducible builds and auditability.
