Artifact comments could be fetched server-side instead of through the frame host, but that switch is off.

What probably matters to youSection of the release

The server-side comment path sits behind tengu_onyx_sluice, default off, with fallback to the existing flow.

What

Fetching comments on an artifact can go through a new server-side path, falling back to the existing frame-host URL flow if the server call errors. The switch is tengu_onyx_sluice and its built-in default is off, so unless a remote configuration value turns it on, nothing changes for you.

Details
  • A fallback after a failed server call is recorded as server_primary_fell_back.

Feature flag
tengu_onyx_sluice Off by default, switched on for this account

The shipped code defaults this off, and the flag server returned on for the one account this site reads on this version. That is the reading that makes the entry above worth a second look, and it still says nothing about your account.

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.

Read once, for one account on one subscription tier, against v2.1.228. It isn't a statement about your account. What a flag value here can and cannot tell you

What has happened since
Flag reading moved The flag server now returns on for tengu_onyx_sluice, 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.
