So I see your OS as a seL4 + semantic layer?
And, yes, in re: semantic layer, I have't talked bout that part much, yet, but given my experience at Stardog(.com), I've implemented a lakehouse+documents layer that extends convention agentic memory tiers (working, semantic, episodic, procedural) with what I call "institutional" memory, i.e., what an invoice reconciliation agent, say, needs to know from C360 data sources, etc.
But I still miss BEAM's supervision trees and hot code loading. That was a bit clunky in Rust.
