+# Golden Set for Patch Validation (in BinaryIndex)
+
+## Module
+BinaryIndex
+
+## Status
+IMPLEMENTED
+
+## Description
+Golden set analysis pipeline and API controller for curated binary patch validation test cases.
+
+## Implementation Details
+- **Modules**: `src/BinaryIndex/__Libraries/StellaOps.BinaryIndex.Analysis/`, `src/BinaryIndex/StellaOps.BinaryIndex.WebService/Controllers/`
+- **Key Classes**:
+  - `GoldenSetAnalysisPipeline` (`src/BinaryIndex/__Libraries/StellaOps.BinaryIndex.Analysis/GoldenSetAnalysisPipeline.cs`) - runs validation analysis against golden set definitions
+  - `GoldenSetController` (`src/BinaryIndex/StellaOps.BinaryIndex.WebService/Controllers/GoldenSetController.cs`) - REST API for golden set CRUD operations with filtering, pagination, and ordering
+    - `POST /api/v1/golden-sets` - create golden set definitions
+    - `GET /api/v1/golden-sets` - list with status/component/tag filters
+    - `GET /api/v1/golden-sets/{id}` - get by ID
+  - `GoldenSetValidator` (`src/BinaryIndex/__Libraries/StellaOps.BinaryIndex.GoldenSet/Validation/GoldenSetValidator.cs`) - validates golden set definitions
+- **Interfaces**: `IGoldenSetStore`, `IGoldenSetValidator`
+- **Models**: `GoldenSetDefinition`, `GoldenSetListQuery`, `GoldenSetListResponse`, `GoldenSetCreateRequest/Response`
+- **Enums**: `GoldenSetStatus` (Draft, Active, etc.), `GoldenSetOrderBy`
+
+## E2E Test Plan
+- [ ] Create a golden set via `POST /api/v1/golden-sets` and verify it is stored with Draft status
+- [ ] List golden sets with component filter and verify only matching sets are returned
+- [ ] Get golden set by ID and verify all fields including metadata are returned
+- [ ] Run golden set analysis pipeline against a known binary pair and verify patch validation result
+- [ ] Verify golden set validation rejects definitions with invalid CVE references
+- [ ] Verify pagination and ordering work correctly with multiple golden sets
