It can send these from a recorded copy.\n\nWhen a particular mode is on, Claude Code now skips that step unless a remote switch, tengu_copper_ledger, is turned on. The switch is off unless it is turned on remotely.\n\n**Why**\n\nIn that mode the recorded copy is no longer used for this unless the switch is on. Outside that mode nothing changes.\n\n- Flag `tengu_copper_ledger`: Off in both readings (read for one account on one subscription tier against v2.1.317; this account: off, anonymous baseline: off, compiled default: off) 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: Tools\n- Tier: Under the hood\n- Useful: 1\/5\n- Signal: 2\/5\n- Scope: individual\n- Heads-up: no"}
