Both fall back to off when the server sends nothing. Code picks one or the other depending on conditions it checks, and a readiness check now also depends on one of them.\n\n**Why**\n\nNothing changes for you unless the server turns one of these switches on.\n\n- Flag `tengu_violin_willow`: Not enough to say (read for one account on one subscription tier against v2.1.290; this account: no value returned, anonymous baseline: no value returned, 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- Flag `tengu_violin_wood`: Off in both readings (read for one account on one subscription tier against v2.1.290; 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: Internals\n- Tier: Nothing to try yet\n- Useful: 1\/5\n- Signal: 3\/5\n- Scope: individual\n- Heads-up: no\n- Present in the build but not switched on"}
