[Bug] Persistent login prompts despite repeated auth logout/login cycles

Bug Description

I'm intermittently and repeatedly prompted to /login again mid-session, even though I've fully run claude auth logout and claude auth login and confirmed the login succeeded. This started right after I was added to a Team organization — my account now has both a Personal Pro account and a Team account under the same email, and I explicitly selected the Team account during login.

The prompt reappears at unpredictable points during an active session (not just at the start of a new terminal/session), which suggests the session's auth/token state is being invalidated or is flip-flopping between the two accounts rather than a normal expiry.

Steps to Reproduce

1. Have an email with both a Personal Pro subscription and a Team org membership.
2. Run claude auth logout, then claude auth login and select the Team account.
3. Use Claude Code normally in a session.
4. At a random point mid-session (no fixed time interval observed), Claude Code prompts to /login again, even though auth was never explicitly invalidated.

Expected Behavior
Once logged into the Team account, the session should remain authenticated as Team until an explicit logout, token expiry, or org-side revocation — it should not spontaneously fall back to re-prompting for login mid-session.

Actual Behavior
Repeated, unpredictable re-prompts to log in again, despite claude auth logout + claude auth login cycles completing successfully each time.

Suspected Cause
Possible auth-state confusion/race between the Personal Pro and Team credentials for the same email — e.g. the client may be caching or overwriting the wrong account's token, or a background refresh is picking the wrong account.

Environment / Debug Info

• Platform: win32 (Windows 11)
• Terminal: windows-terminal
• Claude Code version: 2.1.259 (commit 9b549c8d1c72)
• Install method: native (C:\Users\holmes0527\.local\bin\claude.exe)
• Auto-updates: enabled, channel latest
• Feedback ID: 6246ebf2-b285-4889-adc0-28a86ba83cad
• claude auth status output when the session is (currently) working correctly:

``json
{
"loggedIn": true,
"authMethod": "claude.ai",
"apiProvider": "firstParty",
"analyticsDisabled": false,
"projectsDirectory": "C:\\Users\\<user>\\.claude\\projects",
"email": "<redacted>",
"orgId": "<redacted>",
"orgName": "<redacted>",
"subscriptionType": "team"
}
``
(Note: this looks correct when checked right after logging in — the problem is that mid-session, Claude Code still prompts to log in again despite this reporting a healthy Team-authenticated state.)

• Account setup: one email with two subscriptions — Personal Pro and Team — Team was selected explicitly at login.
• claude doctor reports no installation issues; Remote Control is disabled by org policy (unrelated).
