Dan reported that am/shazam cherry-pick was failing with a particular
CXL series.[1]

Specified msgid is not present in the series, cannot cherrypick
The reason is series processing failed to detect that a non reply follow
on message containing a patch was not a replacement for the original.
The way this patch was submitted (without a 'Re:' subject prefix) is
actually a good thing. This is because a reply would have implied a v2
to the original patch rather than a follow on patch as intended.
Teach b4 to interpret a thread like this by adding the additional patch
to the series with a warning. The series can then be applied as normal
or with a cherry-pick as was necessary in this case.
A run after the fix looks like this:
