@@ -40,6 +40,8 @@ Minimal DSL seeds for interoperability (low surface area)
 - PolicyBlock { safety, exposure_rules }
 - GoC registry entry schema (adapter_id, supported_domains, contract_version)
 
+- Enhancements (seeded DSL primitives): We extended the DSL seeds to include PrivacyBudget, AuditLog, and PolicyBlock seeds to bootstrap governance and privacy features in tests and adapters. See dsl_seed.py for concrete dataclass definitions and helper functions (PrivacyBudgetSeed, AuditLogSeed, PolicyBlockSeed, and extended seed_end_to_catopt_full).

 How to run and contribute
 - Run tests and packaging checks: bash test.sh
 - Build the package for distribution: python3 -m build
