-- [Bitcoin Core #26567][] Wallet: estimate the size of signed inputs using descriptors FIXME:Murchandamus
+- [Bitcoin Core #26567][] updates the wallet to estimate the weight of a
+  signed input from the [descriptor][topic descriptors] instead of doing a signing dry-run.
+  This approach will succeed even for more complex [miniscript][topic miniscript]
+  descriptors, where the dry-run approach was insufficient.
