I'm just wondering: you know what architecture you want to go to now and you have the tests... can't you just let Claude refactor it to the better architecture?

Also 1600 lines... didn't any agent reviewing the diffs point that out?

You're also adding a lot to claude.md, I dunno how much that file has grown but a big claude.md file with many instructions, I don't think the ai will be able to remember all those rules
