Without this check, it's possible to send a probe HTLC w/ a valid payment address but invalid payment hash that gets settled. Because there was no assertion that the HTLC's payment hash matches the invoice, the link would fail when it receives an invalid preimage for the HTLC on its commitment.
channeldb
The channeldb implements the persistent storage engine for lnd and
generically a data storage layer for the required state within the Lightning
Network. The backing storage engine is
boltdb, an embedded pure-go key-value store
based off of LMDB.
The package implements an object-oriented storage model with queries and mutations flowing through a particular object instance rather than the database itself. The storage implemented by the objects includes: open channels, past commitment revocation states, the channel graph which includes authenticated node and channel announcements, outgoing payments, and invoices
