[BUG] Claude Code Pro API Error: Rate limit reached on brand new Pro account with 0-2% usage

What's Wrong?

Every request returns API Error: Rate limit reached immediately on a brand new Claude Pro account that has never been meaningfully used. Usage dashboard shows 2% session and 0% weekly — yet every prompt is blocked.
This appears to be the same server-side bug documented in #29579 and #39581, where the rate limiter incorrectly locks out accounts that have not exceeded any quota.

What Should Happen?

Expected Behavior
Requests should succeed normally. The account has barely any usage and is well within Pro plan limits.

Actual Behavior
Every single request is immediately rejected with API Error: Rate limit reached, regardless of prompt length or complexity. The error appeared from the very first use of this account.

Environment

Claude Code version: 2.1.87
OS: Ubuntu (Linux)
Login method: Claude Pro Account
Plan: Claude Pro ($20/month)
Account created: today (March 29, 2026)
ANTHROPIC_API_KEY env var: not set

Evidence (screenshots attached)

Screenshot 1 — Status: Shows active Claude Pro Account login
Screenshot 2 — Usage: Shows 2% session usage, 0% weekly usage
Screenshot 3 — Error: Shows API Error: Rate limit reached on a normal prompt, same session

The three screenshots together demonstrate the contradiction: active Pro plan + near-zero usage + rate limit error on every request.

Additional Context
I also have access to a separate Team plan account through my employer (different email, different organization). I am using this Pro account exclusively for personal projects. There is no ANTHROPIC_API_KEY environment variable set. Logging out and back in did not resolve the issue.
A server-side reset of the rate limit state for my account would be appreciated.
