+### Restart the host

+The image rebuild does not reload the **host**. Codex's host contribution
+(`src/providers/codex.ts`) registers the `/home/node/.codex` bind mount + env

+first Codex turn fails with `EACCES` writing `/home/node/.codex/config.toml` —
+with no mount, Docker auto-creates the dir root-owned and the non-root container
+user can't write to it.

Do **not** run it through Claude Code's `!` prefix or an agent's Bash tool (no interactive TTY there — the prompts stall and nothing completes).
