Credits desync: CLI blocked with "usage limit hit" while UI showed 312 credits, web ui dropped to 0 with no usage recorded. #18083

What version of Codex CLI is running?

What issue are you seeing?

I was actively using Codex CLI and had ~312 credits remaining (confirmed in the UI shortly before the issue).

I then attempted to submit a message and received:

■ You've hit your usage limit. Visit https://chatgpt.com/codex/settings/usage to purchase more credits or try again at Apr 17th, 2026 6:10 AM.

At the same time:

CLI blocked further usage entirely
Codex cloud usage page suddenly showed 0 credits remaining
No new usage entries were logged for today
Credits appeared to drop from ~312 → 0 instantly
No visible consumption in usage history explaining the drop

This looks like a state desync between billing/credits and enforcement, or a backend accounting issue.

What steps can reproduce the bug?

Use Codex CLI normally with remaining credits (~312 in my case)
Submit a prompt
CLI responds with usage limit error
Check usage UI:
Credits now show 0
No corresponding usage logged for the drop

Thread ID:

019d6d0a-82da-7560-a51f-35dabdd0a229

What is the expected behavior?

Credits should decrement transparently and consistently
CLI enforcement should match UI-reported credit balance
Usage history should reflect any credit consumption
Users should not be blocked if credits are available

Additional information

This appears to be a critical billing/state consistency issue rather than a simple quota limit.
