[Bug] Anthropic API Error: Out of extra usage despite available quota balance

Bug Description
Claude Code throws "out of extra usage" error despite having available plan quota and extra usage balance.

Environment

• Claude Code version: 2.0.76
• OS: macOS (Ghostty terminal)
• Install method: pnpm
• Login method: Claude Max Account
• Plan: Max 5x

Error
API Error: 400 {"type":"error","error":{"type":"invalid_request_error","message":"You're out of extra usage. Add more at claude.ai/settings/usage and keep going."}}

Sample request IDs: req_011CZrRExfXMEuxkfvEHuHfA, req_011CZrSMb83ePo3dZFt1YiNo

Account state at time of error

• Session usage: 3% used, ~3 hours until reset
• Weekly usage (all models): 4% used
• Weekly usage (Sonnet only): 3% used
• Extra usage: enabled, CA$139.55 balance, 2% of monthly cap used

Troubleshooting already attempted

• Removed duplicate Claude Code install (had both pnpm and nvm versions)
• Ran claude logout and claude login
• Confirmed no ANTHROPIC_API_KEY environment variable set
• Confirmed authenticated to Max plan organization

Error persists after all of the above. Dashboard state clearly does not match the error being returned.
