@U02E9K53C9L repro welcome. could this be a caching issue? delete .shadow-cljs in doubt. also, are you perhaps using a user.clj?

https://github.com/babashka/sci#troubleshooting

I saw that, but am not using user.clj. So it seems deleting .shadow.cljs does resolve the issue – the build compiles every time after I delete it. But the next build (without delete) reproduces the issue.

I’m using shadow with sci in several projects but never saw this. Is your project public ?

in case it's not public, is it possible to make a repro?

I think I've got it.

It was user.clj, just through Calva's https://calva.io/connect-sequences/#settings-for-adding-custom-sequences. I must have been requiring nses that depend on the nses that use sci.core.

Adding the guidance from the troubleshooting section resolves it.

Thanks!
