Members discuss the Windows gateway adding an in-tree venv with a mismatched ABI to the import shim or sys.path, tied to a reported pydantic_core import error and Group Chat worker exits. One member also mentions Kanban card turns and an off-loop heartbeat write, which look like an additional adjacent change.
