Claude Code v2.1.238 ·

The tengu_ethereal_nova gate's built-in default is now on

A feature switch that used to default off now defaults on when the server says nothing.

What

Separately visible in the bundle, the fallback value for this feature switch changed from false to true, so with no server-side answer it now resolves on for accounts that also pass the capability check it is combined with. The bundle only shows the fallback; the live value still comes from remote config.

Details
  • The check reads return rQ() && it("tengu_ethereal_nova", !0);, so the capability check in front of it still has to pass.
Evidence

return rQ() && it("tengu_ethereal_nova", !0);

Strings lifted out of the shipped bundle, so the claim above can be checked against them.

Feature flag
tengu_ethereal_nova On for this account, and not off by default

The flag server returned on for the one account this site reads, and nothing in this release compiles it off by default. The compiled default is shown below, and says which it is when we cannot read one: a fifth of gates compile in a string or a number rather than on or off, and most published releases have no gate table behind them at all. No client can see what the server returns for your account.

Flag reading moved The flag server now returns off for tengu_ethereal_nova, read as this account. A reading is one sample. Claude Code evaluates its flags remotely, so no client sees the targeting rule behind a value and this says nothing about your account.
