The ActiveThorns directive in parameter files accepts a “secret” thorn “Cactus” that corresponds to the flesh and its Cactus:: parameters.

The testsuite system is however not aware of this and will not run tests with that pseudo-thorn activated and claims that there are missing thorns. Eg test NRPyEllipticET_test_conformally_flat_BBH on https://einsteintoolkit.github.io/tests/
