[api-Hypernova]

Description:

The V1 Forking Probability Matrix highlights group membership updates as the significant leading cause of forks, more so than other commit operations.

Using the data gathered from previous and ongoing fork matrix testing, work on a MINIMAL repro case. Recommended starting point:

• Single node
• Group size = 1
• ONLY adding new members
• No network chaos or other operations
