In a perfect world, every system and external API would expose a standardized interface for versioning its own immutable state, so you'd be able to rollback and time travel across multiple such systems.
Not sure what else we can do in this world other than tightly control outbound requests and provide enough visibility into those requests for a human|agent to try and undo changes.
Happy to hear your thoughts - what would you like to see us take this?
Yeah tbh I think this might be close to impossible to do as it probably 1) requires alignment that every stateful system needs a rollback capablity 2) it needs to be standardized which will probably take a minimum of 2 years after consensus (and that's probably conservative).
I'd love to learn more on how egress can be handled securely in sandboxes, and in general also ingress as this has some security impact - as soon as you allow reading from an external system you open up a new threat vector. Curious to understand whether you have any strategy for network access?
