Vibecoding idea I don't have time for: Take SQLite's version control system Fossil (where all the code history and issue tracking and a bunch of other stuff live in one sqlite file) and figure out how to make it work really well with agents.

Maybe it does already - it's old and there is probably a good amount of training data on it, and I'm sure it's amazing if the SQLite guys built.
