+# Batch Exception Loading for Policy Evaluation
+
+## Module
+Policy
+
+## Status
+VERIFIED
+
+## Description
+Efficient batch loading of policy exceptions for large-scale evaluation, avoiding N+1 queries when evaluating many findings against exception records.
+
+## Implementation Details
+- **Batch Exception Loader**: `src/Policy/StellaOps.Policy.Engine/BatchEvaluation/BatchExceptionLoader.cs` -- bulk exception loading
+  - `BatchEvaluationModels.cs` -- batch evaluation request/response models
+- **Batch Evaluation Endpoint**: `src/Policy/StellaOps.Policy.Engine/Endpoints/BatchEvaluationEndpoint.cs` -- API for batch evaluation
+- **Batch Context**: `src/Policy/StellaOps.Policy.Engine/BatchContext/BatchContextService.cs` -- batch context management
+  - `BatchContextModels.cs` -- batch context models
+- **Batch Context Endpoint**: `src/Policy/StellaOps.Policy.Engine/Endpoints/BatchContextEndpoint.cs` -- API for batch contexts
+
+## E2E Test Plan
+- [ ] Submit a batch evaluation request with 100+ findings and verify all exceptions loaded efficiently
+- [ ] Verify batch context is created and reused across evaluations in the same batch
+- [ ] Measure evaluation latency for batch vs. individual exception loading
+- [ ] Verify batch evaluation API returns results for all submitted findings
+- [ ] Test batch context cleanup after evaluation completes
