author-first formulation for Perrone

Based on your clarification, I would not write that Perrone says abolition itself did “more than” legal termination.

I would formulate her point as:

Giuliana Perrone (2023) argues that the formal abolition of slavery did not automatically eliminate the social and institutional legacies of slavery; these legacies continued to shape the lives and freedom of formerly enslaved African Americans after emancipation.

The logical structure is:

Perrone's claim:

formal abolition occurred.

But:

its social consequences were not automatically erased.

So you're not saying:

abolition legally did X + socially did Y.

You're saying:

abolition legally did X, but legal abolition did not automatically eliminate what slavery had already produced socially and institutionally.

That distinction is essential.
