One is a new state for a \"lean rewrite\" mode. The other is a new category for background commands that are kept, where a background command is one that keeps running while Claude does other work.\n\n**Why**\n\nNeither is something you can switch on or see directly. They relate to how Claude Code handles background commands across a turn.\n\n- Area: Background Shells\n- Tier: Under the hood\n- Useful: 2\/5\n- Signal: 4\/5\n- Scope: individual\n- Heads-up: no"}
