#836 added the model and proofs for the partial authorization algorithm and #725 added proofs for batched evaluation.
The Rust library also has has a batched authorization algorithm which is not modeled or proven correct.

We should add a Lean model of this algorithm and prove that it is correct. Correctness theorem will be the same as for evaluation but showing that the authorization decision is the same rather than the result of evaluation.
