+# Evidence: single-react-rag-log-projections
+
+## Static verification
+
+- `git diff --check`: passed.
+- Existing legacy files were checked and have no diff: `LookupKnowledgeTool`, `QueryLogsTools`, `ChatService`, `AiOpsService`, and `ToolInvocationRecorder`.
+- OpenSpec strict validation: passed for `single-react-rag-log-projections`.
+
+## Script/build verification
+
+- `mvn -q -DskipTests compile`: passed.
+- Focused projection tests: passed (`RagResultProjectorTest`, `QueryLogsResultProjectorTest`).
+- Adapter tests: passed (`ToolAdapterTest`).
+- Stage regression suite: passed (`CanonicalInvocationStoreTest`, `ToolBoundaryTest`, ACI/Core/retry/key/config/ChatController tests plus the new projection tests).
+
+## Coverage
+
+- RAG: bounded exact excerpts, duplicate document IDs, internal field exclusion, `NO_EVIDENCE`, truncation and framework ID.
+- Logs: logical scope, Mock provenance, pattern aggregation, timeline sampling, sensitive value redaction, empty result and bounded output.
+- Boundary: adapters use the existing canonical lifecycle and do not return raw payloads.
+
+## Not verified in this stage
+
+- Real Redis connectivity and live CLS/MCP integration.
+- Diagnosis Agent/application cutover and end-to-end Maven runtime flow.
