What is the meaning of the error :malli.core/potentially-recursive-seqex?

I believe it's documented on README &/ source code.

I looked through both and it’s not readily apparent to me.

I'll try: it's a design choice to keep the parsing fast and simpler: You can't recur from a sequence itself, but you can recur from a element in the sequence. http://malli.io has an example how hiccup works.

e.g. wrap the :ref inside a :schema forcing it out of the secuence to it's own schema.

That’s extremely helpful. Thanks!

I am struggling to define a schema as defn metadata, which accepts any values as inpu (as I only one to validate output) How could this look like ?

assuming your function is 1-arity, you could do:

(defn my-func {:malli/schema [:=> [:cat :any] output-schema]}
  ... ; body goes here)
