    lgtm: Minimal cov and ft increase:

    https://cirrus-ci.com/task/4855101825744896?logs=ci#L6891 (master):

    0mocked_descriptor_parse                  [#2760](/bitcoin-core-qa-assets/2760/)	DONE   cov: 16901 ft: 97969 corp: 2102/3231Kb lim: 974476 exec/s: 2 rss: 663Mb
    

    However, the fuzz target was recently changed in https://github.com/bitcoin/bitcoin/commit/262260ce1e919613ba60194a5861b0b0a51dfe01, so it may have rediscovered fuzz inputs that previously achieved the same coverage in real code, but were invalidated by the recently added checks (I haven’t checked that).

    Looks good to merge in either case. Thanks!
