Module parse 

Parser for git diff-tree -r -U0 --no-renames patch output.

Count-driven: the @@ -a,b +c,d @@ header states exactly how many removed and added lines follow, so hunk bodies are consumed by count, never by prefix sniffing. (Prefix sniffing silently drops deleted lines that start with --: deleting a line --help emits ---help, which a startswith("---") header guard eats. That was a real latent bug in the validated prototype.)

Unknown lines are hard errors, not skips — a parser that guesses is how hunks get lost silently.
