It now passes only for `claude-opus-4-5`, `claude-opus-4-6` and `claude-opus-4-7`. Before, any other model could still pass through a second, fallback check. That fallback has been removed.\n\n**Why**\n\nModels outside those three may no longer get whatever this check switches on.\n\n- Area: Models\n- Tier: Under the hood\n- Useful: 2\/5\n- Signal: 2\/5\n- Scope: individual\n- Heads-up: no"}
