What's Wrong?

Title: Active Pro subscription not recognized — /login ends with "Claude Max or Pro is required to connect to Claude Code" (server-side entitlement, status shows Pro)

What's wrong:
I have an active, paid Claude Pro subscription that works normally on claude.ai. The same account has been in continuous use with Claude Code for 12+ months with no change on my end. Claude Code now blocks access despite /status showing the Pro plan.

/status output:

• Login method: Claude Pro account
• Email: brittobj@mail.uc.edu
• Organization: brittobj@mail.uc.edu's Organization

Steps to reproduce:

1. Run /login
2. Select "1. Claude account with subscription"
3. Browser OAuth flow completes successfully
4. Result: "Claude Max or Pro is required to connect to Claude Code" with an "Upgrade to Max or Pro" button

Troubleshooting already done (none resolved it):

• /logout, /login repeatedly
• claude update to latest version
• Full terminal restart
• Confirmed no ANTHROPIC_API_KEY set in shell profile or environment
• Subscription confirmed active on claude.ai under the same email

This matches the pattern in several open issues where the entitlement/access-control layer doesn't sync with an active subscription. The block occurs server-side during OAuth, before any client-side change can affect it. Happy to provide claude doctor output, session IDs, HAR files, or a screen recording.

Environment:

• Claude Code version: [run claude --version and paste]
• OS: [your OS]
• Login method per /status: Claude Pro account

What Should Happen?

Claude Code should recognize my active Pro subscription and let me send messages normally, as it has for the past 12+ months.

Error Messages/Logs

On /login, OAuth completes in browser, then returns: "Claude Max or Pro is required to connect to Claude Code" with an "Upgrade to Max or Pro" button. No local error logs are generated — the block happens server-side during the OAuth entitlement check.

Steps to Reproduce

1. Open Claude Code
2. Run /login
3. Select "1. Claude account with subscription"
4. Complete OAuth flow in browser
5. Result: "Claude Max or Pro is required to connect to Claude Code" — despite active Pro subscription
