What's Wrong?

All previously archived sessions in the Claude Code web interface have become active again. Sessions that were intentionally archived (after merging branches/completing work) are now showing in the active sessions list.

All archived sessions have become active again, appearing in the main sessions list alongside genuinely active sessions.

What Should Happen?

Archived sessions should remain archived and not appear in the active sessions list.
