Public-reader artifact gate moved to a wrapper and now keys on the asset token alone

Not switched on
Useful2 Signal3
Artifacts

Reading an artifact as a public non-member reader still refuses; the switch stays off in this build.

Public artifact reading sits behind the tengu_cobalt_plinth_sedge gate, which falls back to false, so the refusal message always shows.

Feature flag
tengu_cobalt_plinth_sedge Not enough to say

Nothing here resolved what this flag was doing on this version, so nothing here should be read as on or off.

This account: no value returned · anonymous baseline: no value returned · compiled default in v2.1.225: on

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 v2.1.225. It isn't a statement about your account. What a flag value here can and cannot tell you

What

The refusal shown when an artifact is served to a public, non-member reader moved out of the boot-response parser into a wrapper around it, and now fires whenever no asset token comes back.

Details
  • The error text is unchanged: "artifact read failed: this artifact is served to you as a public (non-member) reader, and reading public artifacts that way is not enabled yet".
  • Public reading remains behind the remote-config gate tengu_cobalt_plinth_sedge, whose in-source fallback is false, so it is off in this build.
Evidence

tengu_cobalt_plinth_sedge

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