When the server sends nothing, or the lookup fails, Claude Code treats it as on.\n\nIt is used by the checklist screen shown while a cloud session (a session running on Anthropic's servers) is being created. When the switch is on and another condition is also met, the screen runs one action, and only once.\n\n**Why**\n\nBecause the built-in fallback is on, this step runs unless the server turns it off.\n\n- Flag `tengu_velvety_mango`: Not enough to say (read for one account on one subscription tier against v2.1.309; this account: no value returned, anonymous baseline: no value returned, compiled default: on) These values were read against a different version of Claude Code, so treat them as the nearest reading available instead of one taken on this release.\n- Area: Cloud Sessions\n- Tier: Under the hood\n- Useful: 1\/5\n- Signal: 2\/5\n- Scope: individual\n- Heads-up: no"}
