This points at sessions started ahead of time and handed out when needed. Nothing in this build shows spare-session creation being reachable by default, so whether any are made is decided elsewhere.\n\n**Details**\n\n- The related lock that keeps one session's work from another now records whether it is bound to this specific machine.\n- A dedicated error type was added for two resume attempts racing each other.\n\n**Evidence**\n\n`boundToThisMachine`\n\n- Area: Cloud Sessions\n- Tier: Under the hood\n- Useful: 2\/5\n- Signal: 4\/5\n- Present in the build but not switched on"}
