Codex CLI cannot use Luna Reserve after standard usage limit is exhausted

Summary

Codex CLI appears unable to use the Luna Reserve entitlement after the standard usage limit is exhausted, even though the same ChatGPT account has Luna Reserve available in Codex App.

Reproduction

1. Use the same ChatGPT Plus account in Codex App and Codex CLI.
2. In Codex CLI 0.149.1, select model gpt-5.6-luna.
3. Exhaust the standard 5-hour limit.
4. Run /status.
5. Send a minimal prompt such as: Reply only with: OK.

Observed behavior

Codex CLI reports:

5h limit: 0% left
Weekly limit: 73% left

The minimal prompt fails with:

You've hit your usage limit.

At the same time, Codex App, using the same account, shows:

Luna Reserve: 100% remaining

Expected behavior

If Luna Reserve is intended to be available across Codex clients, the CLI should automatically use the reserve after the standard allowance is exhausted, or clearly explain that the entitlement is App-only.

Environment

• Codex CLI: 0.149.1
• Plan: ChatGPT Plus
• Model: gpt-5.6-luna
• Authentication: ChatGPT account

The CLI already appears to support multiple rate-limit snapshots generically, so this may be an entitlement/request-context parity issue rather than only a /status display issue.

Could you clarify whether Luna Reserve is intentionally limited to Codex App, or whether ChatGPT-authenticated Codex CLI sessions should be able to use the same reserve entitlement?

Start with the Codex CLI 0.149.1 reproduction using ChatGPT authentication: exhaust the standard limit for gpt-5.6-luna, check /status, and send the minimal prompt. Compare the CLI's reported limits and failure with Codex App's Luna Reserve; done when the intended entitlement behavior is established and the CLI either uses the reserve or clearly reports that it is App-only.
