Unclear Which feature these switches control is not shown.
What
Claude Code has two new switches whose value comes from Anthropic's servers: tengu_violin_willow and tengu_violin_wood. 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.
Why
Nothing changes for you unless the server turns one of these switches on.

This account: no value returned · anonymous baseline: no value returned · compiled default in v2.1.290: 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.
tengu_violin_woodOff in both readings
The flag server returned off for the account this site reads and for the anonymous baseline. A reading of off cannot rule out a rollout these two readings sit outside of.
