## Problem

Werkator runs the builds and the review gate of all werk repositories, with their secrets.
Since PR#153 the Codex review only advises on Werkator.
On werkrevisor the gate works since werkrevisor PR#105:
an open Codex finding held the merge, and after the fix the automerge followed without a human.
The user chose Werkator as the second repository with `gate`.

## Non-Goals

- No change of the code of Werkator.

## Solution

- `.werkrevisor.toml`: `[codex] mode = "gate"`.
- AGENTS.md: the branch protection also requires `ai-review/codex`.
- Werkbaum: the node of the Codex review below `#process` holds the merge.
- Version v1.42.2, internal.

The runner reads the mode at the head of `main`, so this PR itself is not held by `ai-review/codex`.
After the merge the human adds `ai-review/codex` to the required status checks of `main`,
e.g. with `tools/branch-protection` of werkrevisor, first with `--dry-run`.
With the workstation off, a Werkator PR waits with the status `pending`.
