def has_minimal_ranks(self) -> NDArray: # bool array, shape = stack_shape (per element; uniform ranks vary)
True (per stack element) if the frame has structurally minimal ranks:
left==right,up==down, and up/left equal the minimal ranks for the shape (reduced over the mode axis). Non-enforcing; not a correctness precondition (docs/numerical_contracts.md).- Return type:
