When it takes over one of these, it now records two timings: how long it waited for a token file, and how long it took to apply the session's setup.\n\n**Why**\n\nNothing changes on screen. The timings measure how fast these pre-started processes get going.\n\n- Area: Startup\n- Tier: Under the hood\n- Useful: 1\/5\n- Signal: 2\/5"}
