If the check is aborted, it re-raises the abort instead of silently treating it as a failed check, and a cleanup step now always runs afterward to clear its timer.\n\n**Why**\n\nThis distinguishes a genuinely cancelled lookup from a failed one, and prevents leftover timers from lingering after the check finishes or is cancelled.\n\n- Area: Sandbox Network\n- Tier: Under the hood\n- Useful: 1\/5\n- Signal: 1\/5"}
