Description

Signal's ML-KEM Braid protocol needs a variant of ML-KEM where encapsulation is split in two steps.

Would this "incremental ML-KEM" be within the scope of this crate?

Apparently Signal has implemented this protocol using libcrux which supports incremental ML-KEM. https://github.com/signalapp/SparsePostQuantumRatchet/blob/main/src/incremental_mlkem768.rs

Research direction

Read Signal's ML-KEM Braid specification and compare it with the incremental implementation in src/incremental_mlkem768.rs from SparsePostQuantumRatchet. Determine whether an incremental ML-KEM variant fits this crate's scope; the issue is done when that scope question has a documented decision and an actionable implementation plan.
