T3Tangent.has_minimal_ranks =========================== .. py:method:: t3toolbox.manifold.T3Tangent.has_minimal_ranks() .. code-block:: python def has_minimal_ranks(self) -> bool: True if this tangent's frame has **structurally** minimal ranks. See :py:attr:`T3Frame.has_minimal_ranks`. Minimal rank is *not* a correctness precondition for the verified tangent ops (see :py:meth:`T3Frame.has_minimal_ranks` / the contract catalog); for the numerical check see :py:meth:`has_numerically_minimal_ranks`. Not enforced at construction.
