In `@app/shared/src/transcript/edgeEventMappersArtifacts.test.ts`:
- Around line 113-127: Add a URI-only artifact.created test case to the fallback
coverage in edgeEventMappersArtifacts.test.ts, invoking artifactCreatedBlock
with a payload containing uri but no title or kind, and assert that the
resulting title uses the URI value.

In `@app/shared/src/transcript/edgeEventMappersPermission.test.ts`:
- Around line 23-27: Update the fixture scope construction in
app/shared/src/transcript/edgeEventMappersPermission.test.ts lines 23-27 and
app/shared/src/transcript/edgeEventMappersTools.test.ts lines 23-27 to
conditionally spread runId only when payload.runId is a string, rather than
assigning runId: undefined; leave the existing threadId and scopeOverrides
behavior unchanged.
