- the yfinance cache check names the suite's directory, which may sit under the home on Windows
- POSIX file modes and shell upgrade commands are checked only off Windows

- chatgpt_auth signs in through OpenAI's flow for open-source apps (PKCE, loopback or pasted redirect, verified ID token, plan scope) and keeps the sign-in in ~/.tradingagents/chatgpt-auth.json, readable only by its owner
- access tokens renew under a lock shared across threads and processes, from the refresh token on disk
- `tradingagents login chatgpt` and `tradingagents logout chatgpt`; logout revokes the sign-in at OpenAI
