But the if the shard runs its sharder\nbefore then, currently it will fetch and updates its own range from the\nroot, giving it the first piece of information but not the second.\n\nInterestingly, the response from the root will include *both* shards,\nsince both overlap the range the shard is responsible for. There\u0027s an\nopportunity for an optimization: when our own shard (as retrieved from\nthe root) is shrinking or sharded, we can save all of the shards we\nreceived and get to work immediately, without waiting for the root to\npush to us.\n\nAlso, only expand the acceptor\u0027s shard range if the donor transitioned\nto sharding -- if it was already there, leave it alone.\n\nBetween the two, we can now recover from a sharding split-brain.
