suggestion (non-blocking)

We should probably eventually use a sync.Once pattern to initialize the UUID once since we don't mutate bundles after initialization

[TymKh]

Yeah, I thought in a little bit different direction, I believe we'll eventually move to propagating this uuid as a field of bundle structure, but it'd be better be done once we have some module with shared models. But I anyway understand your concern, I hope we'll address it in future

looks great!

Could you update your PR description with output successfully showing bundles inserted into database with the new schema and UUID?

Otherwise lgtm, good stuff
