/codex:setup returns 401 "OAuth token has expired" despite fresh ChatGPT login

[landonvivian]

Codex CLI works fine from terminal (v0.117.0, auth mode: chatgpt).
Auth.json at ~/.codex/auth.json is populated with valid tokens.
codex launches and runs normally from terminal.

But all plugin commands inside Claude Code (v2.1.88) return:
API Error: 401 - authentication_error - "OAuth token has expired"

This happens even after:

• Fresh codex login from terminal
• /reload-plugins in Claude Code
• pkill -f codex to clear background processes
• Starting a new Claude Code session

macOS, Apple Silicon, Node v25.6.1
