65 * ChannelMonitorUpdate on disk without updating the monitor itself, replaying the journal at

87 * update to ensure you can claim from it in case of a duplicate copy of this ChannelMonitor

90 * In case of distributed watchtowers deployment, the new version must be written to disk, as
91 * state may have been stored but rejected due to a block forcing a commitment broadcast. This
