+ * 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.

* [`Score`] implementation using channel success probability distributions.
*
- * Based on *Optimally Reliable & Cheap Payment Flows on the Lightning Network* by Rene Pickhardt
- * and Stefan Richter [[1]]. Given the uncertainty of channel liquidity balances, probability
- * distributions are defined based on knowledge learned from successful and unsuccessful attempts.
- * Then the negative `log10` of the success probability is used to determine the cost of routing a
- * specific HTLC amount through a channel.
+ * 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.
*
- * Knowledge about channel liquidity balances takes the form of upper and lower bounds on the
- * possible liquidity. Certainty of the bounds is decreased over time using a decay function. See
- * [`ProbabilisticScoringParameters`] for details.
+ * 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)`).
*
- * Since the scorer aims to learn the current channel liquidity balances, it works best for nodes
- * with high payment volume or that actively probe the [`NetworkGraph`]. Nodes with low payment
- * volume are more likely to experience failed payment paths, which would need to be retried.
+ * 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.

- * 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

- *
- * 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

+ * Events are processed by passing an [`EventHandler`] to [`process_pending_events`].
+ *
+ * # Requirements
+ *
+ * When using this trait, [`process_pending_events`] will call [`handle_event`] for each pending
+ * event since the last invocation.
+ *
+ * In order to ensure no [`Event`]s are lost, implementors of this trait will persist [`Event`]s
+ * and replay any unhandled events on startup. An [`Event`] is considered handled when
+ * [`process_pending_events`] returns, thus handlers MUST fully handle [`Event`]s and persist any
+ * relevant changes to disk *before* returning.
+ *
+ * Further, because an application may crash between an [`Event`] being handled and the
+ * implementor of this trait being re-serialized, [`Event`] handling must be idempotent - in
+ * effect, [`Event`]s may be replayed.
+ *
+ * Note, handlers may call back into the provider and thus deadlocking must be avoided. Be sure to
+ * consult the provider's documentation on the implication of processing events and how a handler
+ * may safely use the provider (e.g., see [`ChannelManager::process_pending_events`] and
+ * [`ChainMonitor::process_pending_events`]).
+ *
+ * (C-not implementable) As there is likely no reason for a user to implement this trait on their
+ * own type(s).

+ * At a high-level, the process for deserializing a ChannelManager and resuming normal operation

+ * 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

- * A trait indicating an object may generate events.

- * Events are processed by passing an [`EventHandler`] to [`process_pending_events`].
- *
- * # Requirements
- *
- * See [`process_pending_events`] for requirements around event processing.
+ * A PeerManager manages a set of peers, described by their [`SocketDescriptor`] and marshalls
+ * socket events into messages which it passes on to its [`MessageHandler`].
*
- * When using this trait, [`process_pending_events`] will call [`handle_event`] for each pending
- * event since the last invocation. The handler must either act upon the event immediately
- * or preserve it for later handling.
+ * Locks are taken internally, so you must never assume that reentrancy from a
+ * [`SocketDescriptor`] call back into [`PeerManager`] methods will not deadlock.
*
- * Note, handlers may call back into the provider and thus deadlocking must be avoided. Be sure to
- * consult the provider's documentation on the implication of processing events and how a handler
- * may safely use the provider (e.g., see [`ChannelManager::process_pending_events`] and
- * [`ChainMonitor::process_pending_events`]).
+ * Calls to [`read_event`] will decode relevant messages and pass them to the
+ * [`ChannelMessageHandler`], likely doing message processing in-line. Thus, the primary form of
+ * parallelism in Rust-Lightning is in calls to [`read_event`]. Note, however, that calls to any
+ * [`PeerManager`] functions related to the same connection must occur only in serial, making new
+ * calls only after previous ones have returned.
*
- * (C-not implementable) As there is likely no reason for a user to implement this trait on their
- * own type(s).
+ * Rather than using a plain PeerManager, it is preferable to use either a SimpleArcPeerManager
+ * a SimpleRefPeerManager, for conciseness. See their documentation for more details, but
+ * essentially you should default to using a SimpleRefPeerManager, and use a
+ * SimpleArcPeerManager when you require a PeerManager with a static lifetime, such as when
+ * you're using lightning-net-tokio.

+ * * Processing [`Event`]s with a user-provided [`EventHandler`].
+ * * Monitoring whether the [`ChannelManager`] needs to be re-persisted to disk, and if so,
+ * writing it to disk/backups by invoking the callback given to it at startup.
+ * [`ChannelManager`] persistence should be done in the background.
+ * * Calling [`ChannelManager::timer_tick_occurred`] and [`PeerManager::timer_tick_occurred`]
+ * at the appropriate intervals.
+ * * Calling [`NetworkGraph::remove_stale_channels_and_tracking`] (if a [`GossipSync`] with a
+ * [`NetworkGraph`] is provided to [`BackgroundProcessor::start`]).
*
- * A phantom node payment is a payment made to a phantom invoice, which is an invoice that can be
- * paid to one of multiple nodes. This works because we encode the invoice route hints such that
- * LDK will recognize an incoming payment as destined for a phantom node, and collect the payment
- * itself without ever needing to forward to this fake node.
+ * It will also call [`PeerManager::process_events`] periodically though this shouldn't be relied
+ * upon as doing so may result in high latency.
*
- * Phantom node payments are useful for load balancing between multiple LDK nodes. They also
- * provide some fault tolerance, because payers will automatically retry paying other provided
- * nodes in the case that one node goes down.
+ * # Note
*
- * Note that multi-path payments are not supported in phantom invoices for security reasons.
- * Switching between this struct and [`KeysManager`] will invalidate any previously issued
- * invoices and attempts to pay previous invoices will fail.
+ * If [`ChannelManager`] persistence fails and the persisted manager becomes out-of-date, then
+ * there is a risk of channels force-closing on startup when the manager realizes it's outdated.
+ * However, as long as [`ChannelMonitor`] backups are sound, no funds besides those used for
+ * unilateral chain closure fees are at risk.

- * 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
