Obviously it doesn't, how even could it? Read the issue description, it wouldn't make sense if something like that was possible, considering how it was implemented...
Obviously, I wasn't claiming that it would WORK for cross-model subagents, but that this would be a limiting behavior requiring use of the Codex harness to operate if this was paired with model-level limitations on using specific tools to spawn sub-agents.
Or maybe not so obvious to you.
It literally cannot.

I know, but you were questioning (before investigating) if maybe it did, which I'm saying should have been obvious it wouldn't, if you had understand how this was encrypted.

Yes, if you want to use Sol + Ultra + sub-agents, you'd need to use the endpoints provided by OpenAI, as (again), the content is encrypted on OpenAI's side, it's not technically possible for other platforms to implement OpenAI's encryption.
And of course this doesn't impact anyone else not using Codex + Sol + Ultra + launching subagents, it's the specific combination that is "protected", not the individual pieces.
I think you don’t really understand how this works if you think the open source harness is all that’s manipulated to determine system behavior.
