- * 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

+ * 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

+ * No updates to the channel will be made which could invalidate other [`ChannelMonitor`]s

+ * 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

+ * 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.
+ *
+ * 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.
*
- * 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.
+ * The liquidity bounds are decayed by halving them every [`liquidity_offset_half_life`].
*
- * 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.
+ * 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.

*
* # Order
*

- * - Transactions confirmed in a block must be given before transactions confirmed in a later
- * block.
+ * - Transactions which are confirmed in a particular block must be given before transactions
+ * confirmed in a later block.
* - Dependent transactions within the same block must be given in topological order, possibly in

- * reconfirmation.
+ * - All unconfirmed transactions must be given after the original confirmations and before *any*

+ * # Avoiding Duplicate Payments
+ *
+ * If a pending payment is currently in-flight with the same [`PaymentId`] provided, this
+ * method will error with an [`APIError::InvalidRoute`]. Note, however, that once a payment
+ * is no longer pending (either via [`ChannelManager::abandon_payment`], or handling of an
+ * [`Event::PaymentSent`] or [`Event::PaymentFailed`]) LDK will not stop you from sending a
+ * second payment with the same [`PaymentId`].
+ *
+ * Thus, in order to ensure duplicate payments are not sent, you should implement your own
+ * tracking of payments, including state to indicate once a payment has completed. Because you
+ * should also ensure that [`PaymentHash`]es are not re-used, for simplicity, you should
+ * consider using the [`PaymentHash`] as the key for tracking payments. In that case, the
+ * [`PaymentId`] should be a copy of the [`PaymentHash`] bytes.
+ *
+ * Additionally, in the scenario where we begin the process of sending a payment, but crash
+ * before `send_payment` returns (or prior to [`ChannelMonitorUpdate`] persistence if you're
+ * using [`ChannelMonitorUpdateStatus::InProgress`]), the payment may be lost on restart. See
+ * [`ChannelManager::list_recent_payments`] for more information.

- * May generate SendHTLCs message(s) event on success, which should be relayed.

*
* In general, a path may raise:
- * * APIError::RouteError when an invalid route or forwarding parameter (cltv_delta, fee,
+ * * [`APIError::InvalidRoute`] when an invalid route or forwarding parameter (cltv_delta, fee,
* node public key) is specified.
- * * APIError::ChannelUnavailable if the next-hop channel is not available for updates
+ * * [`APIError::ChannelUnavailable`] if the next-hop channel is not available for updates
* (including due to previous monitor update failure or new permanent monitor update
* failure).
- * * APIError::MonitorUpdateFailed if a new monitor update failure prevented sending the
