+## Remote-Safe Worker Mode
+
+Keep the desktop Codex App and ChatGPT mobile remote-control pinned to the main
+`~/.codex/auth.json` account. For quota-heavy work on another stored account,
+run Codex through an isolated worker home instead of switching the shared auth:
+
+```bash
+codex-worker --email worker@example.com -- login status
+codex-worker --email worker@example.com -- exec -C "$PWD" "summarize this repo"
+```
+
+`codex-worker` materializes `~/.jnslayer2/codex-homes/<email>/auth.json` from
+the stored account file and sets `CODEX_HOME` only for that process. It does not
+modify `~/.codex/auth.json`, restart Codex.app, or affect ChatGPT mobile
+remote-control presence.
+
+To protect the mobile remote-control account from accidental shared-auth
+switches, run the guard with the ChatGPT account used on the phone:
+
+```bash
+CODEX_REMOTE_MAIN_EMAIL=main@example.com ./Scripts/codex-remote-main-guard
+```
+
+If `~/.codex/auth.json` no longer matches that account, the guard restores the
+stored auth from `~/.jnslayer2/accounts/<email>/auth.json` and re-enables the
+Codex app-server remote-control daemon. Run it from launchd or another scheduler
+if you want continuous protection.
