## Problem

Since PR#88 the runner can review PRs with the Codex CLI, but no repository has chosen it yet.
The user chose werkrevisor and werkator to start with `advise`.

The systemd unit of PR#88 puts Node v22.17.1 on the `PATH`.
The Codex CLI there is 0.149.0, too old for `gpt-6-astra`; the update to 0.162.1 went to the default Node of nvm, v24.21.0.

## Non-Goals

- No `gate`: the Codex review only advises.
- werkator gets its own PR in its repository.

## Solution

- `.werkrevisor.toml`: `[codex] mode = "advise"`.
- The systemd unit loads nvm and takes its default Node, so it starts the CLI that `npm install -g` updated last.
- Werkbaum: `#model.codex.on`; `#model.codex.eval` and `#model.codex.gate` are deployed.
- Version 0.34.1.
