Claude Authorize Issue

# Claude OAuth credentials repeatedly disappear after successful authentication ## Environment - CodexBar: 0.50.0 (121) - macOS: 27 Public Beta - Claude Code: Latest - Apple Silicon Mac ## Summary Claude authentication succeeds and usage appears correctly. After several minutes, CodexBar loses the OAuth credentials and displays: > Claude OAuth credentials not found. Run `claude` to authenticate. Running the authentication flow again fixes it temporarily, but the problem always returns. ## Steps to reproduce 1. Open CodexBar. 2. Authenticate Claude when prompted. 3. Confirm Claude usage is displayed correctly. 4. Wait several minutes. 5. Claude usage disappears. 6. The message "Claude OAuth credentials not found. Run `claude` to authenticate." appears again. ## Expected Claude should remain authenticated until the OAuth token actually expires. ## Actual CodexBar repeatedly loses the Claude OAuth credentials and requires re-authentication even though Claude Code itself is still logged in. ## Additional notes - Claude Code continues to function normally. - Re-authentication only fixes the issue temporarily. - This appears similar to issues #1970 and #1844, but authentication initially succeeds before failing again.
