+
+## Classification
+
+standard-light
+
+## Task Status
+
+| Task | Status | Notes |
+| --- | --- | --- |
+| Issue and OpenSpec setup | Done | `ISS-005` and the initial OpenSpec artifacts were created. |
+| Implementation | Done | Recorder contract, lookup persistence path, evidence summary semantics, and degraded-path tests were implemented. |
+| Verification | Done | Targeted offline tests and compile verification passed. |
+
+## Verification
+
+### Script Verification
+
+- Command: `mvn -q "-Dtest=ToolInvocationRecorderTest,ToolTraceSummaryServiceTest,ChatServiceSequentialAgentTest,LookupKnowledgeToolTest" test`
+- Result: passed
+- Notes: Covers recorder contract, summary semantics for success/failure/no-evidence, and `ChatService` fallback / degraded paths.
+
+### Static Verification
+
+- Command: `mvn -q -DskipTests compile`
+- Result: passed
+
+## Open Questions
+
+| Question | Current position |
+| --- | --- |
+| Should deduped retrievals be counted separately from generic no-hit events in future evaluation metrics? | Deferred to P1-B; this change preserves enough structure to decide later. |
