t3toolbox.backend.geometry.ManifoldGeometryOps.inner(a, b)

def inner(self, a, b):

The coordinate <.,.> on tangents (Hilbert-Schmidt on an orthonormal, gauged frame), per-element over the leading stacks (K+C) – shape = stack, a 0-d scalar unstacked, matching the uniform twin and the frontend MANIFOLD.inner (review H3-5).
