I've been really enjoying claude design but my biggest critique of it (and frankly how vanilla claude handles files in general) is that it has no native conception of git-like version control. In code land you can work around this with harnesses so there's only so much harm claude code/opencode can do, but to your point in small biz land when it's putzing around with a system of record without rewindability, things could get really messy really fast.

A couple more thoughts here - the hard part is not just the data side of it, it's replaying/unplaying actions. Many actions are non-reversible. Code is clean in the same way that google docs is clean. But for many business processes, some actions just can't be unwound once started. If claude initiates a wire that it shouldn't, no amount of git technology will undo that wire.

Realistically, git for business is hourly backups. Though, so much of business software has moved to SaaS, so that's difficult to do yourself and instead you need to rely on every individual service having revisions and rollbacks.

ZFS?
