Detailed Description

One key exchange's derivation inputs, passed by reference.

Every value here is fixed for the whole of a KEX and read by each of the six derivations, so it travels as one pointer: an argument list this wide spills past the register window and pays for it on every call, at the deepest call depth in the library.
