Read a couple more papers over breakfast!

The Nucleus of a Multiprogramming System is an interesting insight into how to design an early operating system, especially as relates to building a hierarichal set of processes.

Policy/Mechanism Separation in Hydra describes what must have been one of the first microkernel concepts I’ve seen so far. While the paper is very outdated in terms of the implementation, the approach of only providing mechanisms in the OS kernel and leaving everything else to a hierarchy of processes still resonates strongly.
