notes
The Codex SDK variant bypasses the Codex Rust runtime entirely. The
host program drives `openai.chat.completions.create({stream:true})`
or the Responses API directly and supplies its own tools/MCP. There
is no daemon, no built-in tool catalogue, and no session-on-disk
convention — all of that is the host program's responsibility.
