Description

Implement the recommendations from research-current-openai. Read that task's log via wg show research-current-openai for the verified codex model strings + tier mapping.

Goal: a user running wg init --route codex-cli (or wg init -m codex:<something>) gets a working all-codex setup — including agency meta-tasks (.evaluate-*, .flip-*, .assign-*) running on codex, not silently falling back to claude:haiku.

Scope

Update the codex-cli route in wg init to write:
- [agent].model and [dispatcher].model set to the balanced/sonnet-equivalent codex tier
- [models.evaluator], [models.flip], [models.assigner] set to the cheap/haiku-equivalent codex tier
- Any other per-role overrides that today default to claude:haiku
If the current codex:o1-pro default is stale, replace it with the current top-tier model name from research.
Add a deprecation/migration path: existing configs with the old defaults should warn (via wg config lint) and wg migrate config should rewrite them.
Document the change: update the codex-cli section of the relevant docs (probably docs/config-ux-design.md or a setup guide) with the new defaults.

Validation

Failing test written first: wg init --route codex-cli --dry-run output contains the new [models.*] sections AND the updated [agent]/[dispatcher].model strings
Live smoke: in a fresh tmpdir, run wg init --route codex-cli then wg config show — confirm all four model strings are codex-prefixed (no claude: anywhere unless explicitly chosen)
Live smoke: run a tiny task end-to-end on this fresh project and confirm the spawned agent uses codex (check wg agents for executor=codex, OR check WG_EXECUTOR_TYPE in the spawned process env)
Live smoke: confirm the agency pipeline (.evaluate-* / .flip-*) also runs on codex on this project — not claude:haiku. Inspect the spawned meta-agent's executor.
wg config lint flags old codex configs and wg migrate config rewrites them
cargo build + cargo test pass with no regressions
Permanent smoke scenario added under tests/smoke/scenarios/ with this task id in owners
cargo install --path . was run before claiming done

## Description
Implement the recommendations from research-current-openai. Read that task's log via `wg show research-current-openai` for the verified codex model strings + tier mapping.

Goal: a user running `wg init --route codex-cli` (or `wg init -m codex:<something>`) gets a working all-codex setup — including agency meta-tasks (`.evaluate-*`, `.flip-*`, `.assign-*`) running on codex, not silently falling back to claude:haiku.

## Scope
1. Update the `codex-cli` route in wg init to write:
   - `[agent].model` and `[dispatcher].model` set to the balanced/sonnet-equivalent codex tier
   - `[models.evaluator]`, `[models.flip]`, `[models.assigner]` set to the cheap/haiku-equivalent codex tier
   - Any other per-role overrides that today default to claude:haiku
2. If the current `codex:o1-pro` default is stale, replace it with the current top-tier model name from research.
3. Add a deprecation/migration path: existing configs with the old defaults should warn (via `wg config lint`) and `wg migrate config` should rewrite them.
4. Document the change: update the codex-cli section of the relevant docs (probably docs/config-ux-design.md or a setup guide) with the new defaults.

## Validation
- [ ] Failing test written first: `wg init --route codex-cli --dry-run` output contains the new [models.*] sections AND the updated [agent]/[dispatcher].model strings
- [ ] Live smoke: in a fresh tmpdir, run `wg init --route codex-cli` then `wg config show` — confirm all four model strings are codex-prefixed (no `claude:` anywhere unless explicitly chosen)
- [ ] Live smoke: run a tiny task end-to-end on this fresh project and confirm the spawned agent uses codex (check `wg agents` for executor=codex, OR check WG_EXECUTOR_TYPE in the spawned process env)
- [ ] Live smoke: confirm the agency pipeline (`.evaluate-*` / `.flip-*`) also runs on codex on this project — not claude:haiku. Inspect the spawned meta-agent's executor.
- [ ] `wg config lint` flags old codex configs and `wg migrate config` rewrites them
- [ ] cargo build + cargo test pass with no regressions
