 - **Preview Blob Lifecycle.** Character-library and Rehearser local voice previews now revoke replaced or completed
   object URLs, reducing retained browser memory during repeated auditioning.
+- **Character Library Smoke Coverage.** Added deterministic browser coverage for opening Characters / Cast, profile

 - **Security Regression Coverage.** Added a Python test gate for character metadata validation, private-download URL
   rejection and oversized JSON request rejection.
 - **Navigation Reliability.** Rehearser phase requests now survive the feature-module initialization boundary.
