 `js_repl` exposes these globals:
 
-- `codex.state`: mutable object persisted for the current kernel session.
 - `codex.tmpDir`: per-session scratch directory path.
 - `codex.tool(name, args?)`: executes a normal Codex tool call from inside `js_repl` (including shell tools like `shell` / `shell_command` when available).
 - To share generated images with the model, write a file under `codex.tmpDir`, call `await codex.tool("view_image", { path: "/absolute/path" })`, then delete the file.
