SSIP is flexible: it is capable of performing both external surgery, that is surgery between two codeblocks, and internal surgery, that is surgery within the same codeblock. Under the hood, it performs linear algebra over $\\mathbb{F}_2$ governed by universal constructions in the category of chain complexes.
