Summary

The Clarity PCU is simple. The control board is an Infineon (Cypress) ARM MCU, controlled components (so far identified) are

QTY16 ROHM BM60051 gate drivers (see ./BM60051FV-C.PDF)
a pre-charge relay
some temperature sensors
a battery bus current sensor

Connections

Control Unit <=> Power Module

Control -> Power board is QTY1 32-pin cable (probably QTY2 wires per driver), QTY1 12-pin cable.

Control Unit <=> Outside world

There's a 30-pin connector wired to the other side of the control board.

Cooling

Almost all the internal space is dry, except for a cooling pipe squashed in the center. I know coolant is one-way, I just don't know which has to be cooler (the copper core or the gates?).

For prototyping, all of the components can be briefly run without coolant.
