 - Run tests with: ./test.sh
 - Extend: implement real ADMM solver, richer DP, and additional adapters.
 - Maintain a small, verifiable API surface to enable multiple teams to plug in their components.

+New Extensions (Proposed):
+- Adapters: Added two starter toy adapters (InverterControllerAdapter, NeighborhoodBatteryAdapter) to bootstrap interop with local controllers. They are exported from the package for quick experimentation.
+- DSL Sketch: Added idea165_commonsgrid_community_managed/dsl.py as a lightweight DSL sketch for LocalProblemDSL, SharedSignals DSL, PlanDelta DSL, and PrivacyBudget DSL to bootstrap community policy and problem representations.
+- Publishing Mark: READY_TO_PUBLISH marker file to signal readiness after CI/tests pass.

+"""DSL Sketches for CommonsGrid core primitives.
+
+This module provides lightweight dataclass-backed DSL primitives that sketch
+the intended canonical representations used for CommunityPolicy, LocalProblem,
+SharedSignals, PlanDelta, PrivacyBudget, and AuditLog blocks.
+
+These are intentionally small and opinionated scaffolds to bootstrap a DSL
+without pulling in heavy dependencies. They can be extended to integrate with the
+GovernanceLedger and EnergiBridge as the project matures.
