Description
During [a recent incident in CC](https://cockroachlabs.atlassian.net/wiki/spaces/IM/pages/3064889507/2023-06-13+multiple+nodes+crashing+on+mr+host+cluster) a multi-region host cluster had a set of 3 crash looping nodes due to a bad range split.
The fix was to patch the bad nodes with a custom binary that would prevent the nodes from crashing on startup so that our tooling could merge the range back together. This issue is intended to have the KV team explore how to use some of our LoQ tools in an offline capacity where we are unable to restart a node due to the issue being investigated.
