A fallback is the value Claude Code uses when Anthropic's servers send nothing for that switch. The server can still set a different value for each account.\n\n- Flag `tengu_marble_heron`: Not enough to say (read for one account on one subscription tier against v2.1.307; this account: no value returned, anonymous baseline: no value returned, compiled default: not a boolean we can read) 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: Internals\n- Tier: Under the hood\n- Useful: 1\/5\n- Signal: 2\/5\n- Scope: individual\n- Heads-up: no"}
