* [Fixed a data race](https://github.com/lightningnetwork/lnd/pull/11019) in the
legacy cooperative close state machine, which was advanced from both the link
goroutine and the peer goroutine with nothing synchronizing the two. The link
now reports a flushed channel to the peer's channel manager instead of driving
the closer itself, so every step of a close runs on a single goroutine. The
same change has the RBF closer validate the remote party's delivery script in
all cases, rather than only when an upfront shutdown script was on record for
that peer, and rejects an absent script instead of treating it as nothing to
check.
