How do versions and variants work in Studio?

The Versions control lists Published and All snapshots so you can restore a historical flowchart by date.

In-flow exploration uses the AI / multi-armed-bandit node to try and reinforce paths. Recommendations can Apply as variant to insert an alternate branch; web flows can also be reached with a variant key in the URL. Dashboard Improve Agents shows one Generate card per agent, not a row per version UUID.
