frames_equal

t3toolbox.safety.frames_equal(data1, data2, rtol=None)

def frames_equal(data1, data2, rtol=None):

Numerical equality of two frames given as nested core tuples (e.g. T3Frame.data).

The honest “same tangent space” test: two frames are the same iff their cores are equal. It accepts the value-equal-but-different-object frames a jit round-trip produces, while rejecting a genuinely different frame. rtol defaults to the ambient jax-aware tolerance (falling back to the defaults if unsafe – this is a pure comparison, mode-agnostic).
