OpenClaw 2026.4.26 (be8c246)

After updating to .26, isolated cron jobs using `openai-codex/gpt-5.4-mini` started failing.

`openclaw models list --provider openai-codex` shows:

- openai-codex/gpt-5.4
- openai-codex/gpt-5.5

- openai-codex/gpt-5.4-mini

`gpt-5.4-mini` is shown as configured/authenticated, but the cron run fails with:

{"detail":"The 'openai-codex/gpt-5.4-mini' model is not supported when using Codex with a ChatGPT account."}

Example cron job:

- id: 2c72759b-e54a-43a2-bad6-73cbf1deaae3
- name: Polymarket Weather Scan
- session: isolated
- model: openai-codex/gpt-5.4-mini

Expected:
Either the model should work, or `models list` / cron validation should not present it as usable for Codex ChatGPT OAuth.

Actual:
Cron resolves the configured model, starts the run, then fails at runtime with upstream unsupported-model error.
