For stonewall, in desperation I was even looking for an anagram (new) of allowances!
COD suspender.
Is it just my printer that leaves no white space between lower case r and m? In both 11ac and 19dn I read ‘corn’ as ‘com’ and wondered for a while what the hell was going on.
Nevertheless, an excellent puzzle with 12d being one of the best hidden words I’ve seen.

A tough 9’ for me.
The hiding of STONEWALL was brilliant, but it didn’t hold me up because of a piece of wisdom given to me by this blog – “if you can’t break the clue down look for a hidden”!
Couldn’t parse BARBITURATE, thanks for the explanation Chris
COD CRESTFALLEN

Like others, I enjoyed SUSPENDER and STONEWALL, and there was much else to admire.
Thanks Joker and Chris

18a was my COD and 23a LOI.
like others, a great tip, if all else fails, it’s a hidden and it solved 12d quickly!
many thanks to Chris and Joker.

I was another distracted by Earliest. Another 2 minutes saw me over the line.
I do enjoy Joker’s puzzles. COD to 18a. Thanks to setter and blogger. David
