Public, non-member reads of artifact content are now gated and flagged separately from relay reads

What

When someone without membership access (a "public" or tokenless reader) tries to read an artifact's content or files, Claude Code now checks a permission gate before allowing it. If the check fails, it returns a "tokenless" error; if it passes, the result is now marked with a publicRead flag, separate from the existing relay flag.

Why

This adds a controllable checkpoint for public, non-member artifact reads, so this kind of access can be turned on or off independently of other read paths.

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 v2.1.274. 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_cobalt_plinth_sedge, 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.
