How does this actually work in practice?

I suppose altering instruction count or size still dooms the executable to become non-functional?

Or do all absolute & relative code & data references all get magically updated?

elf and pe have relocation info so u can patch things effectively. binary blobs might be problematic but project targets elf/pe from what i can tell.

there is no magic in computer -_-

Generally binary rewriters will add a new section for the rewritten code/other stuff that needs regeneration (relocations, exception info, the like)
