A handoff is the point where a conversation is passed on in a shortened form after compaction, which means summarising older messages to free up space. If those added messages are refused, the handoff is marked invalid and the reason is given.\n\n**Why**\n\nThis is a safeguard on the compaction handoff, so that a handoff with unacceptable added messages is caught rather than used.\n\n- Area: Compaction\n- Tier: Under the hood\n- Useful: 1\/5\n- Signal: 2\/5\n- Scope: individual\n- Heads-up: no"}
