thanks for this @goofylfg, all changes to comet specific logic should be pushed upstream to https://github.com/cometbft/cometbft so that all forks (including this one) can benefit 🙂

also, in general I think adding CI to fix this issue permanently instead of having one off fixes every now and again

thanks!

agree!,but have tow points want to discuss:

1. some of repetitive words is not in upstream repo, maybe we can revert cometbft related file,
2. then add CI tools to check duplicate word in other repo
   wanna hear your advices~ @evan-forbes

similar to celestiaorg/celestia-node#3360
I will add golanglint dupword CI && then add some //nolint:dupword, but first I will fix cometbft repo
