Track changes in Markdown, for humans and AI

Two quick questions/thoughts:

1) Reading the changes, as a human, is not easy, having a document with a bunch editing marks in it, especially at the rate AI can make edits to things, would be very hard to keep track of, atleast that's how I feel.

2) Since you are tracking the context change forever, as a project developed over time, wouldn't the size of the context grow over time, with no upper bound. Would this cause memory pressure issues once we are talking about a huge codebase and a huge Changedown context?
