It already dropped memory context attached from a laptop in cowork sessions. It now also removes system messages that are marked `persist: false`, meaning they are not meant to be kept.\n\n**Why**\n\nShort-lived system notices no longer carry over into whatever this filter prepares, which may be a hand-off of the session or a saved transcript.\n\n- Area: Elsewhere\n- Tier: Under the hood\n- Useful: 1\/5\n- Signal: 2\/5"}
