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

77 * least a final ChannelMonitorUpdate::ChannelForceClosed which must be delivered to at
78 * least one ChannelMonitor copy. Revocation secret MUST NOT be released and offchain channel

4643 * way you would handle a `chain::Filter` call using ChannelMonitor::get_outputs_to_watch() and
