Codex App Remote SSH fails against a (DevPod) devcontainer with:

SSH codex app - server websocket closed

Local app:

Codex App 26.513.20950
Embedded CLI: codex-cli 0.131.0-alpha.9

Remote devcontainer:

codex-cli 0.131.0-alpha.19
Linux 6.12.76-linuxkit aarch64
SSH host: <devpod-host>.devpod

Direct SSH can find Codex:

ssh <devpod-host>.devpod 'command -v codex && codex --version'
/usr/local/bin/codex
codex-cli 0.131.0-alpha.19

But daemon startup fails:

ssh <devpod-host>.devpod 'codex app-server daemon start'

Error: app server did not become ready on /home/vscode/.codex/app-server-control/app-server-control.sock
Caused by:
  No such file or directory (os error 2)

What steps can reproduce the bug?

Codex App -> Settings -> Connections -> SSH -> DevContainer

What is the expected behavior?
