## 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. |
