### `zero_loss_test` - Drop the redundant type hint in the definition of `a`. ### `tangent_test_three_spheres` - Get the dimension from the expected basis, rather than putting it in by hand. ### `tangent_test_kaleidocycle` - Factor out the realization code, in the same style as `realize_irisawa_hexlet`. - Rename the `irisawa` submodule to `examples`. ### `frozen_entry_test` - Move up into the section for simpler tests, between `zero_loss_test` and `irisawa_hexlet_test`.
