    Research direction

    Start by reviewing the referenced slots_gc.patch and the issue's Interpreter Core context. Trace how objects with empty slots are classified for garbage collection, then identify the relevant tests or add coverage for the requested behavior. Done means such objects are treated as GC types without regressing existing object-layout behavior.
