This is a solid deep dive! Wrapping Claude Code and Codex as child processes sounds like a smart way to isolate and manage complexity.

Isolating language models as child processes is a clever solution. It keeps the system modular and helps manage failures gracefully, which is key given the complexity of coordinating multiple models in a linear coding agent.
