# Evidence Trace Hardening Evidence
|
|
|
|
## Evidence
|
|
|
|
| Source | Evidence | Conclusion | Reported |
|
|
|---|---|---|---|
|
|
| `ToolInvocationRecorder` | Provides a common persistence seam for evidence tools | Contract hardening should build on the existing recorder instead of introducing a new store path | Yes |
|
|
| `LookupKnowledgeTool` | Still constructs `ToolInvocation` rows through a local helper | Retrieval-aware evidence persistence is not yet unified with the recorder contract | Yes |
|
|
| `QueryLogsTools` / `QueryMetricsTools` | Already record evidence invocations through `recordEvidenceTool(...)` | Current gap is semantic alignment, not missing persistence | Yes |
|
|
| `ToolTraceSummaryService` | Merges rows by tool and topic domain and infers evidence level heuristically | Summary rules need explicit handling for failure, no-hit, and dedup cases | Yes |
|
|
| `ChatService` | Falls back to `LOW_CONFID` when verifier output is missing or invalid | These degraded paths exist and should now be covered by focused offline tests | Yes |
