left some comments, nice job.

We should get some docs, its fine in a follow up.

It would be good to do some testing after the merge on leadership rotation latency and what would be the expected time that a block may not be produced while a new leader is being found.

come of the comments from claude look realistic, should have tests for them at least

nit: this can be deleted, this isn't used. (TestGenesisInitialization should be reverted to what's in main)

Integration tests are still failing because TestGenesisInitialization was modified compared to main.
