Nevertheless an interesting idea. Unix pipes are basically concatenative, I've often thought how much mileage you could get out of going more in this direction.
Having said that. This has a lot of forth in it. (Dup, over, rot) I'm not sure the forth way, of passing options in the stack would necessarily work so well in a shell.
You could easily make CUNIX by starting with a log containing the state of a PDP11 at boot and a pure function which appends ignore previous input and the next PDP11 state to it.
I wish I were half as productive as Devine Lu Linvega. Perhaps I should get a sailboat and spend my time hacking without distraction, but I am not a fan of the seas.
It's more than just a grammar. But specifically on that note, I'm assuming you know a POSIX Shell language. Spend some time with Forth and ask yourself if these are experientially the same thing.
Is this not more of a shell than an os?

You might enjoy the "Shell Has a Forth-like Quality" article. It's changed my shell scripting a lot.

It kind of asks "What if we built an OS, but with all data sourced from immutable, append-only logs processed by pure functios?"
Probably not literally realizable right now, but IMHO, the closer we can get, the better

Does this name come from reversing "CP/M"?
It does :) It's CP/M commands(era, ren, etc..) except they work in postfix instead of infix.
Great work as usual.

They've been putting interesting update screenshots on fediverse recently: https://merveilles.town/@neauoire/116823589548151098
maybe I am dumb, but I don't really get how this is different to just piping between commands?

Equifinality is extremely misleading.
Looks like the hardware this runs on has only 64 KB RAM.
Not to be confused with MPC, apparently: https://en.wikipedia.org/wiki/Multimedia_PC
