Fix: TestGetAssignedStatus - Missing rootCtx initialization

Failure Type: Real
Root Cause: Test was not initializing the global rootCtx variable that getAssignedStatus depends on, causing it to return nil
Fix Applied: Added rootCtx initialization with proper cleanup using defer, matching the pattern used in other tests
Verification: All tests now pass (go test ./...)

Fixes bd-9f86-baseline-test
