Let x0 of type ι → ο be given.

Let x1 of type ι → ι → ι → ο be given.

Let x2 of type ι → ι be given.

Let x3 of type ι → ι → ι → ι → ι → ι be given.

Let x4 of type ι → ι → ι → ι → ι → ι be given.

Let x5 of type ι → ι → ι → ι → ι → ι be given.

Let x6 of type ι → ι → ι → ι → ι → ι be given.

Let x7 of type ι → ι → ι → ι → ι → ι → ι → ι → ι be given.

Assume H0: MetaCat_pullback_buggy_struct_p x0 x1 x2 x3 x4 x5 x6 x7.

The subproof is completed by applying H0.
