+ * have been successfully applied, a [`MonitorEvent::Completed`] can be used to restore the
+ * channel to an operational state.
*
- * Even when a channel has been \"frozen\" updates to the ChannelMonitor can continue to occur
- * (eg if an inbound HTLC which we forwarded was claimed upstream resulting in us attempting
- * to claim it on this channel) and those updates must be applied wherever they can be. At
- * least one such updated ChannelMonitor must be persisted otherwise PermanentFailure should
- * be returned to get things on-chain ASAP using only the in-memory copy. Obviously updates to
- * the channel which would invalidate previous ChannelMonitors are not made when a channel has
- * been \"frozen\".
+ * Note that a given [`ChannelManager`] will *never* re-generate a [`ChannelMonitorUpdate`].
+ * If you return this error you must ensure that it is written to disk safely before writing
+ * the latest [`ChannelManager`] state, or you should return [`PermanentFailure`] instead.
*
- * Note that even if updates made after TemporaryFailure succeed you must still provide a
- * [`MonitorEvent::UpdateCompleted`] to ensure you have the latest monitor and re-enable
- * normal channel operation. Note that this is normally generated through a call to
- * [`ChainMonitor::channel_monitor_updated`].
+ * Even when a channel has been \"frozen\", updates to the [`ChannelMonitor`] can continue to
+ * occur (e.g. if an inbound HTLC which we forwarded was claimed upstream, resulting in us
+ * attempting to claim it on this channel) and those updates must still be persisted.
*
- * Note that the update being processed here will not be replayed for you when you return a
- * [`MonitorEvent::UpdateCompleted`] event via [`Watch::release_pending_monitor_events`], so
- * you must store the update itself on your own local disk prior to returning a
- * TemporaryFailure. You may, of course, employ a journaling approach, storing only the
- * ChannelMonitorUpdate on disk without updating the monitor itself, replaying the journal at
- * reload-time.
+ * No updates to the channel will be made which could invalidate other [`ChannelMonitor`]s
+ * until a [`MonitorEvent::Completed`] is provided, even if you return no error on a later
+ * monitor update for the same channel.
*
* For deployments where a copy of ChannelMonitors and other local state are backed up in a
* remote location (with local copies persisted immediately), it is anticipated that all
- * updates will return TemporaryFailure until the remote copies could be updated.

+ * Used to indicate no further channel monitor updates will be allowed (likely a disk failure
+ * or a remote copy of this [`ChannelMonitor`] is no longer reachable and thus not updatable).
+ *
+ * When this is returned, [`ChannelManager`] will force-close the channel but *not* broadcast
+ * our current commitment transaction. This avoids a dangerous case where a local disk failure
+ * (e.g. the Linux-default remounting of the disk as read-only) causes [`PermanentFailure`]s
+ * for all monitor updates. If we were to broadcast our latest commitment transaction and then
+ * restart, we could end up reading a previous [`ChannelMonitor`] and [`ChannelManager`],
+ * revoking our now-broadcasted state before seeing it confirm and losing all our funds.
*
- * At reception of this error, ChannelManager will force-close the channel and return at
- * least a final ChannelMonitorUpdate::ChannelForceClosed which must be delivered to at
- * least one ChannelMonitor copy. Revocation secret MUST NOT be released and offchain channel
- * update must be rejected.
+ * Note that this is somewhat of a tradeoff - if the disk is really gone and we may have lost
+ * the data permanently, we really should broadcast immediately. If the data can be recovered
+ * with manual intervention, we'd rather close the channel, rejecting future updates to it,
+ * and broadcast the latest state only if we have HTLCs to claim which are timing out (which
+ * we do as long as blocks are connected).
*
- * This failure may also signal a failure to update the local persisted copy of one of
- * the channel monitor instance.
+ * In order to broadcast the latest local commitment transaction, you'll need to call
+ * [`ChannelMonitor::get_latest_holder_commitment_txn`] and broadcast the resulting
+ * transactions once you've safely ensured no further channel updates can be generated by your
+ * [`ChannelManager`].
*
- * Note that even when you fail a holder commitment transaction update, you must store the
- * update to ensure you can claim from it in case of a duplicate copy of this ChannelMonitor
- * broadcasts it (e.g distributed channel-monitor deployment)
+ * Note that at least one final [`ChannelMonitorUpdate`] may still be provided, which must
+ * still be processed by a running [`ChannelMonitor`]. This final update will mark the
+ * [`ChannelMonitor`] as finalized, ensuring no further updates (e.g. revocation of the latest
+ * commitment transaction) are allowed.
+ *
+ * Note that even if you return a [`PermanentFailure`] due to unavailability of secondary
+ * [`ChannelMonitor`] copies, you should still make an attempt to store the update where
+ * possible to ensure you can claim HTLC outputs on the latest commitment transaction
+ * broadcasted later.
*
* In case of distributed watchtowers deployment, the new version must be written to disk, as
* state may have been stored but rejected due to a block forcing a commitment broadcast. This
* storage is used to claim outputs of rejected state confirmed onchain by another watchtower,
* lagging behind on block processing.

+ *
+ * Channels are tracked with upper and lower liquidity bounds - when an HTLC fails at a channel,
+ * we learn that the upper-bound on the available liquidity is lower than the amount of the HTLC.
+ * When a payment is forwarded through a channel (but fails later in the route), we learn the
+ * lower-bound on the channel's available liquidity must be at least the value of the HTLC.
+ *
+ * These bounds are then used to determine a success probability using the formula from
+ * *Optimally Reliable & Cheap Payment Flows on the Lightning Network* by Rene Pickhardt
+ * and Stefan Richter [[1]] (i.e. `(upper_bound - payment_amount) / (upper_bound - lower_bound)`).
+ *
+ * This probability is combined with the [`liquidity_penalty_multiplier_msat`] and
+ * [`liquidity_penalty_amount_multiplier_msat`] parameters to calculate a concrete penalty in
+ * milli-satoshis. The penalties, when added across all hops, have the property of being linear in
+ * terms of the entire path's success probability. This allows the router to directly compare
+ * penalties for different paths. See the documentation of those parameters for the exact formulas.
+ *
+ * The liquidity bounds are decayed by halving them every [`liquidity_offset_half_life`].
+ *
+ * Further, we track the history of our upper and lower liquidity bounds for each channel,
+ * allowing us to assign a second penalty (using [`historical_liquidity_penalty_multiplier_msat`]
+ * and [`historical_liquidity_penalty_amount_multiplier_msat`]) based on the same probability
+ * formula, but using the history of a channel rather than our latest estimates for the liquidity
+ * bounds.

- *
- * Implements ChannelMessageHandler, handling the multi-channel parts and passing things through
- * to individual Channels.
- *
- * Implements Writeable to write out all channel state to disk. Implies peer_disconnected() for
- * all peers during write/read (though does not modify this instance, only the instance being
- * serialized). This will result in any channels which have not yet exchanged funding_created (ie
- * called funding_transaction_generated for outbound channels).
- *
- * Note that you can be a bit lazier about writing out ChannelManager than you can be with
- * ChannelMonitors. With ChannelMonitors you MUST write each monitor update out to disk before
- * returning from chain::Watch::watch_/update_channel, with ChannelManagers, writing updates
- * happens out-of-band (and will prevent any other ChannelManager operations from occurring during
- * the serialization process). If the deserialized version is out-of-date compared to the
- * ChannelMonitors passed by reference to read(), those channels will be force-closed based on the
- * ChannelMonitor state and no funds will be lost (mod on-chain transaction fees).
- *
- * Note that the deserializer is only implemented for (BlockHash, ChannelManager), which
- * tells you the last block hash which was block_connect()ed. You MUST rescan any blocks along
- * the \"reorg path\" (ie call block_disconnected() until you get to a common block and then call
- * block_connected() to step towards your best block) upon deserialization before using the
- * object!
- *
- * Note that ChannelManager is responsible for tracking liveness of its channels and generating
- * ChannelUpdate messages informing peers that the channel is temporarily disabled. To avoid
- * spam due to quick disconnection/reconnection, updates are not sent until the channel has been
- * offline for a full minute. In order to track this, you must call
- * timer_tick_occurred roughly once per minute, though it doesn't have to be perfect.
- *
- * Rather than using a plain ChannelManager, it is preferable to use either a SimpleArcChannelManager
- * a SimpleRefChannelManager, for conciseness. See their documentation for more details, but
- * essentially you should default to using a SimpleRefChannelManager, and use a
- * SimpleArcChannelManager when you require a ChannelManager with a static lifetime, such as when

- * The description can be at most 639 __bytes__ long
+ * Implements ChannelMessageHandler, handling the multi-channel parts and passing things through
+ * to individual Channels.
+ *
+ * Implements Writeable to write out all channel state to disk. Implies peer_disconnected() for
+ * all peers during write/read (though does not modify this instance, only the instance being
+ * serialized). This will result in any channels which have not yet exchanged funding_created (ie
+ * called funding_transaction_generated for outbound channels).
+ *
+ * Note that you can be a bit lazier about writing out ChannelManager than you can be with
+ * ChannelMonitors. With ChannelMonitors you MUST write each monitor update out to disk before
+ * returning from chain::Watch::watch_/update_channel, with ChannelManagers, writing updates
+ * happens out-of-band (and will prevent any other ChannelManager operations from occurring during
+ * the serialization process). If the deserialized version is out-of-date compared to the
+ * ChannelMonitors passed by reference to read(), those channels will be force-closed based on the
+ * ChannelMonitor state and no funds will be lost (mod on-chain transaction fees).
+ *
+ * Note that the deserializer is only implemented for (BlockHash, ChannelManager), which
+ * tells you the last block hash which was block_connect()ed. You MUST rescan any blocks along
+ * the \"reorg path\" (ie call block_disconnected() until you get to a common block and then call
+ * block_connected() to step towards your best block) upon deserialization before using the
+ * object!
+ *
+ * Note that ChannelManager is responsible for tracking liveness of its channels and generating
+ * ChannelUpdate messages informing peers that the channel is temporarily disabled. To avoid
+ * spam due to quick disconnection/reconnection, updates are not sent until the channel has been
+ * offline for a full minute. In order to track this, you must call
+ * timer_tick_occurred roughly once per minute, though it doesn't have to be perfect.
+ *
+ * Rather than using a plain ChannelManager, it is preferable to use either a SimpleArcChannelManager
+ * a SimpleRefChannelManager, for conciseness. See their documentation for more details, but
+ * essentially you should default to using a SimpleRefChannelManager, and use a
+ * SimpleArcChannelManager when you require a ChannelManager with a static lifetime, such as when

- * Arguments for the creation of a ChannelManager that are not deserialized.
- *
- * At a high-level, the process for deserializing a ChannelManager and resuming normal operation
- * is:
- * 1) Deserialize all stored [`ChannelMonitor`]s.
- * 2) Deserialize the [`ChannelManager`] by filling in this struct and calling:
- * `<(BlockHash, ChannelManager)>::read(reader, args)`
- * This may result in closing some channels if the [`ChannelMonitor`] is newer than the stored
- * [`ChannelManager`] state to ensure no loss of funds. Thus, transactions may be broadcasted.
- * 3) If you are not fetching full blocks, register all relevant [`ChannelMonitor`] outpoints the
- * same way you would handle a [`chain::Filter`] call using
- * [`ChannelMonitor::get_outputs_to_watch`] and [`ChannelMonitor::get_funding_txo`].
- * 4) Reconnect blocks on your [`ChannelMonitor`]s.
- * 5) Disconnect/connect blocks on the [`ChannelManager`].
- * 6) Re-persist the [`ChannelMonitor`]s to ensure the latest state is on disk.
- * Note that if you're using a [`ChainMonitor`] for your [`chain::Watch`] implementation, you
- * will likely accomplish this as a side-effect of calling [`chain::Watch::watch_channel`] in
- * the next step.
- * 7) Move the [`ChannelMonitor`]s into your local [`chain::Watch`]. If you're using a
- * [`ChainMonitor`], this is done by calling [`chain::Watch::watch_channel`].
- *
- * Note that the ordering of #4-7 is not of importance, however all four must occur before you
- * call any other methods on the newly-deserialized [`ChannelManager`].
- *
- * Note that because some channels may be closed during deserialization, it is critical that you
- * always deserialize only the latest version of a ChannelManager and ChannelMonitors available to
- * you. If you deserialize an old ChannelManager (during which force-closure transactions may be
- * broadcast), and then later deserialize a newer version of the same ChannelManager (which will
- * not force-close the same channels but consider them live), you may end up revoking a state for
- * which you've already broadcasted the transaction.

+ * 2) Deserialize the [`ChannelManager`] by filling in this struct and calling:
+ * `<(BlockHash, ChannelManager)>::read(reader, args)`
+ * This may result in closing some channels if the [`ChannelMonitor`] is newer than the stored
+ * [`ChannelManager`] state to ensure no loss of funds. Thus, transactions may be broadcasted.
+ * 3) If you are not fetching full blocks, register all relevant [`ChannelMonitor`] outpoints the
+ * same way you would handle a [`chain::Filter`] call using
+ * [`ChannelMonitor::get_outputs_to_watch`] and [`ChannelMonitor::get_funding_txo`].
+ * 4) Reconnect blocks on your [`ChannelMonitor`]s.
+ * 5) Disconnect/connect blocks on the [`ChannelManager`].
+ * 6) Re-persist the [`ChannelMonitor`]s to ensure the latest state is on disk.
+ * Note that if you're using a [`ChainMonitor`] for your [`chain::Watch`] implementation, you
+ * will likely accomplish this as a side-effect of calling [`chain::Watch::watch_channel`] in
+ * the next step.
+ * 7) Move the [`ChannelMonitor`]s into your local [`chain::Watch`]. If you're using a
+ * [`ChainMonitor`], this is done by calling [`chain::Watch::watch_channel`].
+ *
+ * Note that the ordering of #4-7 is not of importance, however all four must occur before you
+ * call any other methods on the newly-deserialized [`ChannelManager`].
+ *
+ * Note that because some channels may be closed during deserialization, it is critical that you
+ * always deserialize only the latest version of a ChannelManager and ChannelMonitors available to
+ * you. If you deserialize an old ChannelManager (during which force-closure transactions may be
+ * broadcast), and then later deserialize a newer version of the same ChannelManager (which will

+ *
+ * When we are the funder, because we have to pay the channel closing fee, we bound the
+ * acceptable fee by our [`Background`] and [`Normal`] fees, with the upper bound increased by
+ * this value. Because the on-chain fee we'd pay to force-close the channel is kept near our
+ * [`Normal`] feerate during normal operation, this value represents the additional fee we're
+ * willing to pay in order to avoid waiting for our counterparty's to_self_delay to reclaim our
+ * funds.
+ *
+ * When we are not the funder, we require the closing transaction fee pay at least our
