Artifact live-subscribe now checks agent-peer and sync-live eligibility before connecting, and it is off by default.

The boot-time artifact live-subscribe call now computes agentPeer and syncLive flags before treating a connection as agent-peer/sync-live capable. Both flags come from a helper that requires a gate to be on plus two other conditions, et(e)===null and !rnr(e). This capability is off by default.

tengu_slate_lantern 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 v2.1.257. It isn't a statement about your account. What a flag value here can and cannot tell you
