Thanks for the feedback (both of you!) - when writing this, I envisioned a use case where the secret was static within the application, so it is easy enough for the developer to check their secret is 32 characters and not have to bother with checking that particular error. I didn't use panic because although a non 32 character secret puts my library in an unrecoverable state, it doesn't mean the application implementing the library is also in an unrecoverable state, hence why it returns an error instead of panicing.

Also, in terms of the top comment in this chain, the work server (master) never gets work from the workers, the workers push completed work back to the server, maybe this isn't clear within the current docs. All communication between the worker and server has to be coordinated by the application implementing the library.
