	// Given a wallet end user A, an edge node B, an asset rate of 100 milli-
	// satoshi per asset unit and a flat 0.1% routing fee (to simplify the
	// scenario), the following invoice based receive events can occur:
	// 1. Success case: User A creates an invoice over 5,000 units (500,000 milli-
	// satoshis) that is paid by the network. An HTLC over 500,500 milli-
	// satoshis arrives at B. B converts the HTLC to 5,000 units and sends
	// 354,000 milli-satoshis to A.
	// A receives a total "worth" of 854,000 milli-satoshis, which is already
	// more than the invoice amount. But at least the forwarding rule in `lnd`
	// for B is not violated (outgoing amount mSat < incoming amount mSat).
	// 2. Failure case: User A creates an invoice over 3,530 units (353,000 milli-
	// satoshis) that is paid by the network. An HTLC over 353,530 milli-
	// satoshis arrives at B. B converts the HTLC to 3,530 units and sends
	// 354,000 milli-satoshis to A.
	// This fails in the `lnd` forwarding logic, because the outgoing amount
	// (354,000 milli-satoshis) is greater than the incoming amount (353,530
	// milli-satoshis).
