When a session is resumed after this, Claude Code checks that the saved conversation fits together. These checks used to give only a yes or no about whether something started behind the compaction. They now name what it was: one of your prompts, or a hidden message. They also count command entries that were left out. When a remote switch is on, saved messages that are only partly missing are treated as acceptable.\n\n**Why**\n\nThis changes how sessions resumed after compaction are checked.\n\n- Area: Compaction\n- Tier: Under the hood\n- Useful: 1\/5\n- Signal: 2\/5\n- Scope: individual\n- Heads-up: no"}
