 5. **Human-Readable**: YAML as primary format for git-friendliness
 
+## DAL Technology
+- **Primary**: EF Core v10 DbContext (`EfCore/Context/GoldenSetDbContext.cs`) with 3 entities (definitions, targets, audit_log) in `golden_sets` schema.
+- **Compiled model**: `EfCore/CompiledModels/GoldenSetDbContextModel` generated for runtime performance.
+- **Legacy**: `PostgresGoldenSetStore` still uses NpgsqlDataSource directly (deferred from EF Core conversion). Mixed DAL acceptable per cutover strategy.
+- **SQL migrations remain authoritative**: EF models are scaffolded FROM the SQL schema, never the reverse.
